Removes the lstat/write race, replaces (never follows) a pre-existing symlink, and tightens permissions on an existing world-readable report. Full-write semantics via writeFileSync on the descriptor; temp file removed on any failure. - scope: normalize the git toplevel and cwd with path.resolve before realpath (git reports forward slashes on Windows) and display file paths git-style with forward slashes. - tests: build fixture roots with path.resolve/path.join so containment checks hold on Windows; skip POSIX permission and symlink assertions where the platform cannot support them.

Sep 2026 01:02:36 -0400 Subject: [PATCH 019/269] feat(gateguard): improve first-touch signal quality and session efficiency - Ask class-specific first-touch questions (instruction, test, prose, config, code); code questions are unchanged. - Credit a completed Glob/Grep/LS or shell search from the current human turn that covered the target; Read and exclusion globs never count. - Collapse same-class new-file creations in one directory within a turn. - Add opt-in GATEGUARD_FACT_FORCE_MAX_DENIALS session cap (from #2755). - Always gate sensitive targets, judged on lexical and real paths. - Canonicalize checked-path keys.

A transcript with no + turn start at all gives no credit. +- **Completed, unambiguous result:** the search needs a `tool_result` in the + turn that is not an error (`is_error` of `true` or `"true"`, or content + starting with ``). A tool-use id that appears more than once + never counts. +- **Not the same batch:** searches sent in the gated call's own assistant + message never count, since their results were not seen when the edit was + decided. If the payload's `tool_use_id` is missing or not in the + transcript, the newest assistant message in the turn is excluded instead. A + search without a message id never counts. +- **Stem match:** the target's stem (basename minus its last extension, + lowercased, at least 4 characters) must appear as a whole word — bounded by + non-alphanumeric characters or the ends of the text — in the Glob pattern, + the Grep pattern or glob, or the shell segment. `payment.py` is credited by + a search for `payment` or `payment_service`, but not by one for + `payments`. Exclusions are never a stem source. Generic stems (`index`, `main`, `init`, `__init__`, + `utils`, `util`, `types`, `readme`, `test`, `tests`, `config`, `mod`, + `lib`, `setup`, `app`, `spec`, `helpers`, `common`) never match. +- **Exclusions never credit:** a Grep `glob` is split on top-level commas; + entries starting with `!` are exclusions. In shell segments, `rg -g`/ + `--glob`/`--iglob` values starting with `!`, `grep --exclude`/ + `--exclude-dir`, `fd -E`/`--exclude`, `ls -I`/`--ignore`/`--hide`, + `tree -I`, `git ls-files -x`, git `:!x`/`:^x`/`:(exclude)x` pathspecs, + `find -name`/`-path`/… under `-not` or `!` or followed by `-prune`, and + PowerShell `-Exclude` are exclusions. If an exclusion covers the target + (its glob matches the file name or any directory on its path, or it names + the stem), that search cannot credit the target at all: `rg -g '!widget.py' + TODO .` never credits `widget.py`, while `rg -g '!*.md' widget .` still + does. `--exclude-from`, `--ignore-file`, and `git ls-files -X` hide names + the hook cannot see, so such a segment never credits. File-name globs that + restrict a search (Grep `glob: '*.py'`, `rg -g '*.py'`, `grep --include`, + `find -name`, `tree -P`, `-Include`/`-Filter`) must match the target's file + name for its stem to count. +- **Scope:** `Glob`, `Grep`, and `LS` only credit a target strictly inside the + directory they searched (their `path`, else the tool `cwd`, plus a Glob + pattern's literal leading directories). A Glob without glob characters is a + one-file lookup: it names no directory and credits only files directly in + its directory, never the looked-up file itself. A search whose path is the target is not a search. +- **Shell segments:** a segment without a path operand counts only when it is + recursive (`rg`, `git grep`, `git ls-files`, `find`, `fd`, and `tree` by + default; `grep -r`/`-R`/`--recursive`, `ls -R`, `Get-ChildItem -Recurse`) + and not fed by a pipe; otherwise it reads stdin, not the tree. A segment + whose path operands all resolve to the target only reads the target and + does not count (`ls src/a.py` never credits `src/a.py`). Commands containing + `$( )`, backticks, `<( )`, `>( )`, or heredocs, or longer than 8192 + characters, never credit. +- **Shell scope:** a shell segment only credits a target equal to or inside + one of its path operands (resolved against the tool `cwd`; a glob operand + counts as its literal directory), or inside the `cwd` when it has none: + `rg payment docs` or `grep -rn payment /usr/share/doc` never credit + `src/payment.py`. An input redirection before any operand + (`rg payment < file`) or a `<` inside a word reads stdin and never counts. + After `cd ` in the same command, relative operands resolve against that + directory; after any other directory change, or one in another call of the + turn, only absolute operands count. +- **Directory match (new files only):** a **Write that creates a file that + does not exist yet** may also match when the search named exactly the + target's directory: a Glob `path` plus the pattern's literal prefix (a + pattern that starts with a glob character and has no `path` names no + directory), a Grep or LS `path`, or a shell path operand. For shell + operands, the pattern argument of grep-style tools is skipped (unless + `-e`/`-f`/`--regexp`/`--file`/`-Pattern` supplied the pattern), values of + value-taking flags (`-g`, `--include`, `-name`, `-Filter`, …) are skipped, + trailing `/`, `/*`, and `/**` are dropped, `.`, `~`/`$` paths, and globs + name no directory, and the operand must be an existing directory at the + time of the check. If any Bash/PowerShell call in the turn changes directory + (`cd`, `pushd`, `popd`, `chdir`, `Set-Location`, `sl`, `Push-Location`, + `Pop-Location`), shell directory matching is off for the whole turn; stem + matching still applies. **Edit, MultiEdit, and a Write that overwrites an + existing file match by stem only.** +- **Paths:** relative targets and search paths resolve against the tool's + `cwd`, then `CLAUDE_PROJECT_DIR`, then the process directory. Comparison is + case-insensitive for Windows paths only. Shell commands are read with bash + quoting rules, so on Windows an operand credits when spelled `C:/x/src`; + backslash spellings (`C:\x\src`, quoted or not) and MSYS spellings + (`/c/x/src`) do not credit and the write is denied as usual. +- **Note, not denial:** the credited file is marked checked and + `fact_force_credited` is incremented; the denial count and ordinal are not + touched. MultiEdit credits per entry and denies the first uncredited entry + as before. +- **Falls back to deny:** a missing, unreadable, or non-file transcript, + garbage records, or any internal error mean no credit. + +### Same-turn sibling creation collapse + +When several new files are created in one directory, the answers for each +would be identical, so only the first is denied: + +- Applies to a **Write of a file that does not exist yet** whose class is + `code`, `test`, or `prose`.

The cap is best effort when hooks run concurrently: a lost count update can add a denial, but never lets a new path through early. Opt-in: unset, or any value that is not a whole non-negative integer (surrounding spaces allowed), keeps the deny-every-new-path behaviour; a malformed value is reported once on stderr (`ignoring malformed GATEGUARD_FACT_FORCE_MAX_DENIALS=…; the denial cap is not active.`).

keep +headings stable, since they are the anchors. + +## Module layout + +- `scripts/hooks/gateguard-fact-force.js`: the hook. Owns the shell parser + (`quoteAwareSegments`, `commandBasename`, `SHELL_SEGMENT_SEPARATORS`) that the + destructive Bash/PowerShell detector uses, the state file I/O, the gate + messages, and `run()`. +- `scripts/lib/gateguard-target-class.js`: target identity and classification + for first-touch Edit/Write/MultiEdit targets: canonical path keys, target + classes and their questions, sensitive-target detection and sibling-collapse + eligibility. Stateless; filesystem access is limited to worktree `.git` + checks and realpath/lstat of the target's parent chain. +- `scripts/lib/gateguard-turn-scan.js`: one bounded tail read of the Claude Code + JSONL transcript, walked back to the start of the current turn. Yields the + turn id, the turn's completed non-error search calls (newest first), their + batch ids and the turn's shell commands. +- `scripts/lib/gateguard-search-evidence.js`: decides whether a search in the + current turn covers a target (prior-search credit). Its shell-dependent part + is built by `createSearchEvidence()` from the hook's shell parser, so the + parser the destructive detector relies on is shared, not copied or moved. +- `scripts/lib/gateguard-state.js`: pure helpers for the session-state fields + (counters, per-class counts, sibling dir gates). Reading and writing the + state file, and the one-write event helpers built on it, stay in the hook. + +## Fail to deny + +Every allowance other than a retry of an already-gated target (prior-search +credit, sibling collapse, the denial cap) is an exception to the first-touch +denial, so each one falls back to the denial on any doubt: an unreadable +transcript, a parse failure, an unresolvable path, or an exception. The lib +exports that feed those decisions never throw (they catch and return a +fallback that denies, or no scan at all), so an error cannot escape into credit or +sibling logic. Allowances are never an `allow` permission decision: credit and +sibling passes return `additionalContext`, and the cap pass returns the input +unchanged. + +## Read is not evidence + +`Read` never earns prior-search credit. Claude Code already requires a Read of +a file before an Edit of it, so crediting Read would switch the Edit gate off. +Only `Glob`, `Grep`, `LS` and shell search commands count. + +## Sensitive targets + +Secrets, keys, auth/payment code, migrations and CI workflows always draw the +first-touch denial: prior-search credit, sibling collapse and the denial cap do +not apply to them, and the denial says so. + +- Basename, extension and segment rules are exact, never substrings. +- `.github/workflows/` is also matched below an ancestor (an unverified + worktree, or a target outside the project root). +- A target is sensitive on its lexical path or on its real (symlink-resolved) + location, so `src/tools -> ../auth` cannot launder `src/tools/login.py`. +- A real location that cannot be resolved (dangling symlink, `ENOTDIR`, + `EACCES`, loops), a non-string path, or any error counts as sensitive. + +## Target resolution + +Relative targets resolve against the tool's `cwd` first, then +`CLAUDE_PROJECT_DIR`, then the process cwd. This deliberately differs from +`GATEGUARD_EXEMPT_GLOBS`, whose globs are project-relative (`CLAUDE_PROJECT_DIR` +first). The canonical checked-state key folds `a.py`, `./a.py` and the absolute +path to one gate; Windows-style paths also fold separators and case. + +A target is classified by its project-relative path, so an ancestor such as +`/home/me/tests/proj` never leaks into the class; targets outside the root keep +their absolute path. A Windows-style path has no real location on a POSIX host +(and vice versa), so real-path checks are skipped for it. + +## Target classes + +The first matching class wins: instruction, test, prose, config, code (the +fallback). Cursor `.mdc` rule files are instructions wherever they live. A +basename starting with `.env` is config unless it has a code extension +(`.env.example.ts` is source). Code targets keep the original four questions; +other classes get class-specific questions and a class-specific condensed hint. + +## Worktree prefix + +A `.claude/worktrees//` prefix is stripped only when that worktree is real +(its `.git` exists). Otherwise the path stays under `.claude`, which is an +instruction directory and blocks sibling collapse. + +## Windows name normalization + +Windows ignores trailing dots and spaces in a name and treats `name:stream` as +`name`, so segments are normalized the same way before classification: +`CLAUDE.md.` and `CLAUDE.md::$DATA` both name `CLAUDE.md`. + +## Turn boundaries + +The scan walks the transcript tail backwards to the latest human message or +compaction. Only a user record whose content is a non-empty array of +`tool_result` blocks is a tool result; any other user record is a turn +boundary, which can only shrink the credit window. A compaction summary or +`compact_boundary` record discards the earlier turn and starts a new one. The +tail read is bounded (bytes and lines) to keep the hook fast. + +## Turn identity + +Claude Code stamps every user record of a turn with the same `promptId`, so it +identifies the turn even after the boundary has scrolled out of the tail +window; without one, the boundary record's `uuid` (or a hash of its line) is +used. When no boundary is found, a clipped window is the current turn only if +its `promptId`s agree; two or more mean an unrecognised turn start, and an +unclipped file has no turn at all. + +## Tool result pairing + +A search counts only when it completed without error. A tool-use id that occurs +more than once in the window cannot be tied to one result, so it never counts. + +## Same-batch searches + +Searches in the pending call's own assistant message never count: their results +were not seen when the edit was decided. The batch is located by the pending +`tool_use_id`, or else taken to be the newest assistant message. + +## Ambiguous shell is not evidence + +Command substitution, process substitution, heredocs and PowerShell backtick +escapes make the searched text ambiguous, so a shell command containing any of +them yields no evidence. Commands over 8192 characters yield none either. + +## Directory changes + +A `cd` (or its PowerShell equivalents) in any other shell call of the turn +leaves the cwd of every shell search unknown: shell searches then give no +directory evidence, and their relative operands scope nothing. Within one command, a plain literal `cd ` rebases +later relative operands; any other directory change makes them unresolvable. +Operands that are variables, `~`, or relative to an unknown cwd scope nothing. + +## Stdin is not a tree search + +A search segment that reads stdin (input redirection, a pipe into it, or no +path operand without recursion) searched piped text, not the tree, so it gives +no evidence. A quoted `<` cannot be told from a redirection and is treated as +one. `||` also marks the next segment as piped, which only ever removes +evidence. + +## Search scope + +Each search offers stem texts, candidate directories, the scope the target must +lie in, and path operands. The target must lie inside the scope. A search whose +operands are all the target itself read the target rather than searched for it, +and gives nothing. A `Glob` without glob characters is a single-file lookup: it +names no directory. A `Glob` with an empty literal prefix and no explicit path +names only the implicit cwd, so it gives no directory credit. Directory +evidence from shell operands must name a directory that exists now. +PowerShell `-Path`/`-LiteralPath` values count as operands but never as +directory evidence. + +## Stem matching + +A target's stem (basename without extension) credits it only when it has at +least four characters and is not generic (`index`, `utils`, `config`, ...). +Matching is a word-boundary `indexOf` scan; a `RegExp` is never built from +transcript text. + +## Search filters + +A search that excluded the target never saw it: + +- exclusion values, and the flags that introduce them, are never a stem source; +- an exclusion that names the stem, or matches the file or any directory above + it, blocks credit; +- unreadable exclusion lists (`--exclude-from`, `--ignore-file`, + `git ls-files -X`) and more than 32 exclusions block credit; +- an exclusion glob past the matching bounds, or malformed, counts as covering + the target. + +find: a negated or pruned name test is an exclusion; a plain `-name`/`-iname` is +an include. `--ignore`/`--hide` exclude names only for `ls` (rg's `--ignore` is +a switch). + +## Include filters + +Basename include globs (`--include`, `-g`, `--glob`, `-name`, PowerShell +`-Filter`/`-Include`) that all miss the target stop its stem from crediting. An +include glob past the matching bounds admits the target (the stem, scope and +exclusion checks still apply); a malformed one does not. + +## Glob matching without RegExp + +Filter globs are matched by dynamic programming over glob tokens, never by a +`RegExp`, so a hostile glob cannot cause regex backtracking. Globs are bounded +to 256 characters and 32 brace alternatives. Bracket classes support members, +ranges, `!`/`^` negation and a leading literal `]`; an unclosed class is +malformed. An unbalanced `{` is literal. + +## Flag parsing + +Only path operands can scope a search: + +- flags that consume a value are skipped with it; single-dash clusters + (`-rne PAT`) are read letter by letter, and a value flag ends the cluster; +- for grep-family tools, `rg`, `git grep`, `Select-String` and `fd`, the first + positional is the pattern unless `-e`/`-f` (grep family, `rg`, `git grep` + only; fd's `-e` is an extension) supplied it; +- fd's `-E/--exclude` takes a value; rg's `-r/--replace` takes a value. + +## PowerShell parameter binding + +PowerShell binds a parameter by any unambiguous prefix, by `-Name:value`, and by +comma lists across arguments, so `-Exclude` has many spellings. A parameter that +cannot be resolved may be an exclusion in disguise: neither it nor a value it +may carry is a stem source. + +## New-file detection + +A Write target is new only when `lstat` reports `ENOENT`; any other error counts +as an existing file. Only a new file may earn directory credit or sibling +collapse. + +## Sibling collapse + +A new file whose directory had a sibling gated moments ago passes with a note +instead of a repeat denial. + +- Only code, test and prose targets collapse. Harness and tooling directories + are dot-directories, so any dot segment blocks collapse, as do 8.3 short names + (`CLAUDE~1`), which can alias any directory. +- The gate is keyed by the real directory. A symlinked directory must keep the + class and pass the same screen, and must not be sensitive, so + `src/tools -> .claude/hooks` never collapses. +- A gate opens for the same turn id; without a turn id on either side, for 120 s. + The 120 s rule applies only when there is no transcript at all; an unusable + transcript never collapses. +- A gate stamped in the future, or not created by a denial, is ignored. + +## Denial cap + +`GATEGUARD_FACT_FORCE_MAX_DENIALS` is validated whole (digits only, a safe +integer), not with `parseInt`: a prefix parse would turn `3oops` into a cap. A +malformed value leaves the gate uncapped and says so once on stderr. Once the +session's denials reach the cap, a first touch passes with the input unchanged +and is counted in `cap_allows`. The cap check reads the state the same write +persists, so a lost concurrent update can add a denial but never passes a +target early. Sensitive targets are never capped. + +## State file is untrusted + +The session state file can be edited or corrupted, so every field is validated +on read: counters clamp to non-negative integers, maps are null-prototype and +reject `__proto__`, `constructor` and `prototype` keys, and malformed or +old-shape entries are dropped. `dir_gates` maps `\u0000` to +`{ turn, at, first, ordinal }` and keeps the 50 newest entries. Concurrent +writers are merged on save (checked keys by union, counts by maximum, gates by +newest `at`). Marking a target checked and recording its event happen in one +state write, so an event is never half-recorded. diff --git a/scripts/hooks/gateguard-fact-force.js b/scripts/hooks/gateguard-fact-force.js index 3bf5361a8..1608ccfff 100644 --- a/scripts/hooks/gateguard-fact-force.js +++ b/scripts/hooks/gateguard-fact-force.js @@ -9,17 +9,10 @@ * The act of investigation creates awareness that self-evaluation never did. * * Gates: - * - Edit/Write/MultiEdit (first touch of each file): questions chosen by - * target class (code: list importers, affected API, verify data schemas, - * quote instruction) + * - Edit/Write/MultiEdit (first touch): questions chosen by target class * - Bash/PowerShell (destructive): list targets, rollback plan, quote instruction * - Bash/PowerShell (routine): quote current instruction (once per session) * - * A first touch already covered by a completed search in the current turn, - * or a new sibling of a file just gated, passes with an additionalContext - * note (never an "allow" decision).

It is pure string analysis: no file or transcript +reads, no `RegExp` built from input, and every loop is a single linear pass. + +The profile only ever removes questions, so anything uncertain yields the +unknown profile (every question asked, never trivial): an unsupported +extension, a non-string side, no entries or more than 64, a side over 64 KiB +(UTF-8), more than 256 KiB in total, or any exception. Supported languages, by +extension: JS/TS (`.js .mjs .cjs .jsx .ts .tsx .mts .cts`), Python +(`.py .pyi`), Go, Rust, Java, Kotlin (`.kt .kts`), C# and C/C++ (`.c .h .cc +.cpp .cxx .hpp .hh .hxx`). Shell, Ruby, Makefiles, Swift and everything else +are unknown. + +## Public surface + +A Write always touches the public surface (a new or rewritten module's +surface is all new). For an Edit, any line on either side that declares or +exposes a public name counts, whether it changed or is only context: context +around a public declaration means the edit is inside that symbol. + +- JS/TS: a line starting with the word `export`, `public` or `declare`, or + containing the word `exports` (`module.exports`, `exports.x`). `.d.ts`, + `.d.mts` and `.d.cts` files are all surface. +- Python: `def`, `async def` or `class` whose name does not start with `_` + (dunders such as `__init__` are public), any `__all__`, and a column-0 + assignment or annotation of a public name on a line after the first (the + first line of a snippet may start mid-line). `__init__.py` is all surface. +- Go: `func` (after an optional receiver), `type`, `var` or `const` with a + capitalised name, a `package` line, and any line that starts with a + capital letter (exported fields, interface methods, grouped declarations). +- Rust: lines starting with `pub` (any `pub(...)`), `impl`, `trait`, or + `#[macro_export`. +- Java, Kotlin, C#, C and C++ always touch the surface: package-private Java, + Kotlin's public default, C# partial classes and C linkage make a lexical + answer unreliable. + +An Edit that changes a function body without its declaration line in the +snippet reads as not touching the surface; the local question still asks for +the call sites that rely on the behaviour. + +## Data handling + +`touchesData` looks at every side (both sides of an Edit) as words: identifiers +are split on non-alphanumerics, `_` and camelCase boundaries and lowercased, +so `validate` and `updated` never match `date`. It is true for a data word +(formats such as `json`, `csv`, `yaml`, `parquet`; serialisation; `schema`; +SQL and database words; date/time words such as `date`, `datetime`, +`timestamp`, `strftime`, `utc`; file I/O such as `fs`, `fopen`, `pathlib`), +for `open(`, for adjacent pairs such as `read file`, +`write text`, `read to`, and for SQL keyword pairs anywhere in the text +(`select`+`from`, `insert`+`into`, `create`+`table`, ...). Over-matching only +keeps the data question. + +## Trivial edits + +An Edit is trivial when, for every entry, old and new have the same code once +comments are removed, blank and comment-only lines are dropped, and runs of +whitespace between tokens are folded to one space. Line structure, whitespace +inside strings, and the presence of whitespace between tokens stay code +(`a+b` to `a + b` is not trivial). For Python, leading whitespace of each code +line is code; comment-only lines carry no indentation. + +Comments are `//` and non-nesting `/* */` in the C family and `#` in Python; +C preprocessor lines are code. Strings are single-line `"..."` and `'...'` +(Rust: `"..."` only, with `'x'` char literals told apart from lifetimes). +Anything the lexer cannot read with confidence makes the entry non-trivial: + +- any multi-line string form: JS/Go backticks, Python/Java/Kotlin/C# triple + quotes, Rust raw strings (`r"`, `r#"`), C++ raw strings (`R"`), C# verbatim + and interpolated strings (`@"`, `$"`), Kotlin strings containing `$`, Python + f-strings, and any string that runs to the end of a line; +- in JS/TS, any `/` outside a comment (division and regex literals cannot be + told apart), JSX-like ``, ``; +- a line comment ending in `\` (it continues onto the next line in C and + Make), the trigraph `??/`, whitespace after a line-continuation `\`, a `/*` + inside a block comment, and an unterminated block comment or string. + +Write is never trivial. The profile sees only the snippet, so a comment-looking +line inside a multi-line string that opens and closes outside the snippet +reads as a comment; the trivial pass never marks the target checked and never +applies to sensitive, instruction or config targets, so the next non-trivial +change still meets the full gate. diff --git a/scripts/lib/gateguard-change-profile.js b/scripts/lib/gateguard-change-profile.js new file mode 100644 index 000000000..6396d13ae --- /dev/null +++ b/scripts/lib/gateguard-change-profile.js @@ -0,0 +1,450 @@ +'use strict';

等）、test、prose（`.md` 等）、config（`.json`、`.yaml`、`.env` / `.env.*` 等，`.env.example.ts` 仍属 code）或 code，并提出相应的问题。 +* **按变更内容提问：** 对 code 类目标还会读取变更内容：未触及公开声明的编辑改问"本文件或其模块中依赖所改行为的调用点"，不涉及数据的变更省略数据格式问题；无法可靠判断（不支持的扩展名、超过 64 KiB 等）以及敏感目标时仍问原来的四个问题。 * **事先搜索抵免：** 若当前人类回合内已有成功完成（非错误结果）的 `Glob`、`Grep`、`LS` 或 `rg`/`grep`/`find` 等搜索命中该文件，则以附注代替拒绝。`Read` 从不计入；与被门控调用同批次的搜索、重复的 tool_use id、压缩（compaction）之前的搜索均不计入。文件名词干须按单词边界匹配，且目标须位于所搜索目录之内（shell 片段按其路径参数或 `cwd` 判定范围；参数前的输入重定向 `<` 视为读取 stdin）。仅"创建尚不存在的文件"的写入可按目录匹配，且 shell 参数须是真实存在的目录；回合内出现 `cd` 等切换目录命令时不再按 shell 目录匹配。相对路径按工具的 `cwd` 解析。排除规则从不计入：`Grep` 的 `glob` 中以 `!` 开头的项，以及 shell 中 `rg -g '!x'`、`grep --exclude`/`--exclude-dir`、`fd -E`、`ls -I`、`tree -I`、`git ls-files -x`、git `:!x` 路径规格、带 `-not`/`!` 或后接 `-prune` 的 `find -name`/`-path`、PowerShell `-Exclude` 都不作为词干来源；若排除项覆盖目标（文件名、路径上的目录或词干），该搜索完全不能为其抵免（`rg -g '!widget.py' TODO .` 不抵免 `widget.py`，`rg -g '!*.md' widget .` 仍抵免）。含 `--exclude-from`/`--ignore-file` 的片段不抵免；用 `*.py`、`--include`、`find -name` 等文件名 glob 限定的搜索，只有在其匹配目标文件名时词干才计入。 * **同回合同级文件合并：** 同一目录、同一类别（仅 code、test、prose）的新文件在同一回合内（完全没有 transcript 路径时为 120 秒内）只拒绝第一个，其余以附注放行。config、instruction，以及任何以 `.` 开头的路径段（点文件和所有点目录）或 8.3 短文件名下的文件从不合并；目录按解析符号链接后的真实位置判定和记录；有 transcript 路径但文件缺失、无法读取或得不到回合 ID 时不合并；编辑从不合并。 * **拒绝上限（可选）：** 设置 `GATEGUARD_FACT_FORCE_MAX_DENIALS` 后，会话内首次触碰的拒绝次数达到该值后，新路径直接放行（计入 `cap_allows`）。`GATEGUARD_FACT_FORCE_FULL_DENIALS` 只决定消息详略（消息预算），而此变量决定是否拦截（拒绝预算）。事先搜索抵免和同级合并先于上限判定，不消耗上限；格式错误的值视为无上限，并在 stderr 警告一次。

Reason codes, from +closest to farthest (the closest wins, then the newest): + +| Code | Meaning | +|---|---| +| `same-batch` | it would have credited, but was sent in the pending call's own batch | +| `excluded` | an exclusion covers the target, or include globs miss it | +| `out-of-scope` | its path or operands do not contain the target | +| `stdin-only` | a search segment that read piped input or had no tree operand | +| `not-a-search` | a `Read` of the target, or a non-search shell segment naming it | +| `generic-stem` | the target's name is too generic or short to match any search | + +`previous-turn` is not reported: the scan stops at the turn boundary, and +reading past it would cost a second, larger scan. Ambiguous shell commands +(substitutions, heredocs, over 8192 characters) give no line. The tool name +comes from a fixed set; the detail is the tool input, sanitized like a path, +whitespace-folded and cut to 60 characters.

等搜索命中该文件，则以附注代替拒绝。`Read` 从不计入；与被门控调用同批次的搜索、重复的 tool_use id、压缩（compaction）之前的搜索均不计入。文件名词干须按单词边界匹配，且目标须位于所搜索目录之内（shell 片段按其路径参数或 `cwd` 判定范围；参数前的输入重定向 `<` 视为读取 stdin）。仅"创建尚不存在的文件"的写入可按目录匹配，且 shell 参数须是真实存在的目录；回合内出现 `cd` 等切换目录命令时不再按 shell 目录匹配。相对路径按工具的 `cwd` 解析。排除规则从不计入：`Grep` 的 `glob` 中以 `!` 开头的项，以及 shell 中 `rg -g '!x'`、`grep --exclude`/`--exclude-dir`、`fd -E`、`ls -I`、`tree -I`、`git ls-files

Any allow is a bypass. | +| `redundant` | A denial here would repeat investigation the session already did (a scoped search that names the file, a same-turn sibling, a comment-only edit, a read-only first command). | +| `relevantQuestions` | For code targets, the question ids the change genuinely warrants (see the question table in [design-notes.md](design-notes.md#questions-from-the-change-profile)). | + +Metrics per hook: + +- **Denials**: every denial costs the agent a round trip and context. +- **Redundant denials**: denials on steps labelled `redundant`. +- **Must-deny bypasses**: allows on steps labelled `mustDeny`.

Must be 0 + for the working tree; for a baseline they are the behaviour the branch + changes. +- **Irrelevant questions asked**: for denials of code targets, asked question + ids that are not in `relevantQuestions`. Questions are read from the + numbered list of a full denial, or from the phrases of a condensed one-line + denial (issued after the first three denials of a session); the condensed + rows count the ones asked in condensed denials only. +- **Warranted questions not asked**: `relevantQuestions` ids a code denial did + not ask.

The condensed hint always mentions "data + schemas if any", and the code-Write hint asks for "affected API" but not + whether an existing file already serves the purpose; full denials in the + corpus ask no irrelevant question. +- A one-line edit of a column-0 Python constant reads as not touching the + public surface (the first line of a snippet may start mid-line), so it asks + for local call sites instead of importers (`python-hash-in-string`). +- A comment-only edit of a file without a change profile (`.sh`) keeps the + full questions (`unknown-extension-comment`). +- Latency roughly doubles against `upstream/main` (p50 about 2 ms, p95 about + 8 ms) with the added transcript scanning and path resolution; both stay far + below the 200 ms budget for blocking hooks. + +## Reproduce + +```bash +git fetch upstream main +node scripts/dev/gateguard-eval.js --markdown +node scripts/dev/gateguard-eval.js --markdown --baseline upstream/main --baseline pr +node scripts/dev/gateguard-eval.js --json > gateguard-eval.json +node tests/hooks/gateguard-scenarios.test.js +``` + +`--baseline ` takes any ref and can be repeated (default +`upstream/main`; `pr` is `58a4a0d0`). `--corpus ` points at another +scenario directory. The script exits non-zero when the working tree has a +mismatch, a must-deny bypass, an explicit `allow` decision or a thrown error. + +## Corpus format + +One JSON file per scenario in `tests/fixtures/gateguard-scenarios/`: + +- `name`, `description`; +- `files` (project-relative path to content), optional `dirs` and `symlinks` + (link path to target, relative to the link), created in a temp project; +- optional `root` (a fixed project path, used for Windows-style paths, where + nothing is created on disk) and `env` (extra environment variables); +- `steps`, in order. Each step has an `id`, an optional `note`, the + `transcript` records appended to the session transcript before the call + (human prompts with `promptId`, assistant `tool_use` records with + `message.id`, `tool_result` records, compaction boundaries, and the pending + call's own `tool_use` record), the hook `payload`, and the labels above. + +`{{root}}` and `{{transcript}}` in any string are replaced with the temp +project and transcript paths. Transcripts are the same for every hook: a +step's call is assumed to succeed eventually, so the next step's records start +with its `tool_result`. + +A scenario with `symlinks` is skipped (and reported) where symlinks cannot be +created, such as Windows without the privilege. + +## Limits + +- The corpus is synthetic. Sessions were written to resemble real ones, not + sampled from them, so the denial counts show the direction and size of a + change, not rates to expect in the field. Opt-in metrics + (`GATEGUARD_METRICS=1` and `scripts/gateguard-report.js`) measure real + sessions. +- The labels are the corpus author's judgement, made with the design in mind. + `redundant` and `relevantQuestions` in particular are opinions: a different + author could call the README or CHANGELOG edits after a docs-wide search + redundant, or the test edit after `rg tokenizer src tests` (the stem of + `tokenizer.test.js` is `tokenizer.test`, so that search does not credit it). + Zero redundant denials means the working tree handles the cases this author + judged redundant, not that it never repeats a question. +- Question relevance is read from denial text.

These rules only remove redundant denials: nothing previously allowed is now denied. See `skills/gateguard/SKILL.md`. +- GateGuard first-touch denials ask questions that fit the target: by class (instruction, test, prose, config, code) on its project-relative path, and for code by what the change touches. An edit that changes no public declaration asks for the in-module call sites instead of importers and public API, and the data-schema question is dropped when the change handles no data. Changes the hook cannot read with confidence keep the original four questions word for word. +- GateGuard credits investigation that already happened: a completed, non-error `Glob`, `Grep`, `LS`, or search-style Bash/PowerShell command in the current human turn that names the target and whose scope contains it passes the first touch with a note. `Read` never counts, nor do searches in the same batch, before a compaction, with error results, or whose filters exclude the target. When a denial follows a search that nearly counted, it names that search and why it did not count. +- GateGuard passes comment and whitespace-only edits of code, test and prose files with a note, without marking the file checked, so the next change that alters code is still gated. +- GateGuard asks once for a batch of new files: after a new file is denied, later new files of the same class in the same real directory within the same human turn pass with a note. +- Read-only shell commands (`ls`, `cat`, `rg`, `git status`/`log`/`diff`, `Get-ChildItem`, …) no longer use up the once-per-session routine shell gate; the first other command is still gated (#2573). +- GateGuard session state keyed by a session id or transcript path now expires after 8 idle hours instead of 30 minutes; the project-directory fallback keeps 30 minutes. +- Add opt-in `GATEGUARD_FACT_FORCE_MAX_DENIALS`, a per-session denial cap: once that many first-touch denials have been issued, further new paths pass through (counted in `cap_allows`).

Code comments point here as +`docs/gateguard/change-profile.md#`; keep headings stable, since they +are the anchors. The other decisions are in [design-notes.md](design-notes.md). +## Change profile + +`scripts/lib/gateguard-change-profile.js` reads the change the hook already +receives (Edit `old_string`/`new_string`, each MultiEdit entry for the target, +Write `content`) and derives three booleans: `touchesPublicSurface`, +`touchesData` and `trivial`. It is string analysis of those texts and, for +`trivial`, of the current file text the hook passes in (see +[File context](#file-context)): no reads of its own, no `RegExp` built from +input, and every loop is a single linear pass. + +The profile only ever removes questions, so anything uncertain yields the +unknown profile (every question asked, never trivial): an unsupported +extension, a non-string side, no entries or more than 64, a side over 64 KiB +(UTF-8), more than 256 KiB in total, or any exception. Supported languages, by +extension: JS/TS (`.js .mjs .cjs .jsx .ts .tsx .mts .cts`), Python +(`.py .pyi`), Go, Rust, Java, Kotlin (`.kt .kts`), C# and C/C++ (`.c .h .cc +.cpp .cxx .hpp .hh .hxx`), and shell scripts: POSIX shells (`.sh .bash .zsh`), +PowerShell (`.ps1 .psm1`) and batch (`.bat .cmd`). Ruby, Makefiles, Swift, +fish, PowerShell data files and everything else are unknown. + +## Public surface + +A Write always touches the public surface (a new or rewritten module's +surface is all new). For an Edit, any line on either side that declares or +exposes a public name counts, whether it changed or is only context: context +around a public declaration means the edit is inside that symbol. + +- JS/TS: a line starting with the word `export`, `public` or `declare`, or + containing the word `exports` (`module.exports`, `exports.x`). `.d.ts`, + `.d.mts` and `.d.cts` files are all surface. +- Python: `def`, `async def` or `class` whose name does not start with `_` + (dunders such as `__init__` are public), any `__all__`, and a column-0 + assignment or annotation of a public name (a module constant or variable + that importers can read). The first line of a snippet may start mid-line + (an Edit's `old_string` can begin after the indentation), so there only an + all-uppercase name counts, the constant convention that function locals + rarely use. `__init__.py` is all surface. +- Go: `func` (after an optional receiver), `type`, `var` or `const` with a + capitalised name, a `package` line, and any line that starts with a + capital letter (exported fields, interface methods, grouped declarations). +- Rust: lines starting with `pub` (any `pub(...)`), `impl`, `trait`, + `extern`, or an ABI or trait attribute (`#[macro_export`, `#[derive`, + `#[repr`, `#[no_mangle`, `#[export_name`, and their `#[unsafe(...)]` + forms). +- POSIX shells: a function definition (`name() {`, `function name`), an + `export`, or `declare -x`/`typeset -x`, at any indentation. A sourced + script's functions and exported variables are what other scripts use. +- PowerShell (case-insensitive): lines starting with `function`, `filter`, + `workflow`, `class`, `enum`, `param` (a script's parameters are its + interface), `Export-ModuleMember`, `[CmdletBinding` or `$global:`. +- Java, Kotlin, C#, C, C++ and batch files always touch the surface: + package-private Java, Kotlin's public default, C# partial classes, C linkage + and batch labels reachable by `call :label` make a lexical answer + unreliable. + +An Edit that changes a function body without its declaration line in the +snippet reads as not touching the surface; the local question still asks for +the call sites that rely on the behaviour. + +A member line can be public surface even though its container's declaration +is not in the snippet: a property of an exported interface, a variant of a +public enum, a name in an export list. So, when the hook passes the file text, +the nearest line above the first occurrence that starts at column 0 (skipping +blank lines, comments and decorators; a closing `}`, `]` or `)` there means +the edit is at top level) is read as the enclosing opener: + +- JS/TS: `module.exports`/`exports` assigned an object, array or call, and + `export` (or `export default`) of an interface, enum, type, namespace, + module, `declare`, `{ ... }` list, or `const`/`let`/`var` that is not a + function or arrow: every line inside is surface. An exported class: lines + at the class's member indentation (the first non-blank line after the + opener) are surface; method bodies are not. An exported `function` or + `async function` is a body, as before. +- Python: `__all__` makes every line surface; a public `class` makes an + assignment or annotation of a public name at member indentation (class + attributes, dataclass fields) surface. +- Rust: a `pub` enum, struct, union, trait or `use` makes lines at member + indentation surface. + +The upward scan stops after 4 MiB in total and then counts as surface. The +opener is found by indentation, not by parsing, so it can over-match (a method +body inside an exported object literal counts), which only keeps the importer +question. + +## Data handling + +`touchesData` looks at every side (both sides of an Edit) as words: identifiers +are split on non-alphanumerics, `_` and camelCase boundaries and lowercased, +so `validate` and `updated` never match `date`. It is true for a data word +(formats such as `json`, `csv`, `yaml`, `parquet`; serialisation; `schema`; +SQL and database words; date/time words such as `date`, `datetime`, +`timestamp`, `strftime`, `utc`, `chrono`, `zoneinfo`; encodings such as +`base64`, `encoding`, `msgpack`; browser storage and cookies; data-store +clients such as `redis`, `prisma`, `sqlalchemy`; file I/O such as `fs`, +`fopen`, `pathlib`), for `open(`, for adjacent pairs such as `read file`, +`time now`, `time parse`, `system time`, +`write text`, `read to`, and for SQL keyword pairs anywhere in the text +(`select`+`from`, `insert`+`into`, `create`+`table`, ...). Over-matching only +keeps the data question. + +Shell scripts also touch data with a file redirection (`>`, `>>`, `>|`, `&>` +or `<` followed by a target other than `/dev/null`, `/dev/stdout`, +`/dev/stderr`, `$null` or `nul`; descriptor duplication such as `2>&1` and +`>&2`, heredocs and process substitution do not count), an HTTP or document +tool (`curl`, `wget`, `jq`, `yq`, `xmllint`, `psql`, `tee`, `iwr`, `irm`), +or a PowerShell file or web cmdlet (`Out-File`, `Get-Content`, +`Set-Content`, `Add-Content`, `Invoke-WebRequest`, `Invoke-RestMethod`, +`*-Clixml`; `Import-Csv` matches `csv`). Redirection is found without +reading quotes, so a `>` inside a string also counts. + +## Trivial edits + +An Edit is trivial when, for every entry, old and new have the same code once +comments are removed, blank and comment-only lines are dropped, and runs of +whitespace between tokens are folded to one space. Line structure, whitespace +inside strings, and the presence of whitespace between tokens stay code +(`a+b` to `a + b` is not trivial). For Python, leading whitespace of each code +line is code; comment-only lines carry no indentation. + +Comments are `//` and non-nesting `/* */` in the C family and `#` in Python; +C preprocessor lines are code. Strings are single-line `"..."` and `'...'` +(Rust: `"..."` only, with `'x'` char literals told apart from lifetimes). +Anything the lexer cannot read with confidence makes the entry non-trivial: + +- any multi-line string form: JS/Go backticks, Python/Java/Kotlin/C# triple + quotes, Rust raw strings (`r"`, `r#"`), C++ raw strings (`R"`), C# verbatim + and interpolated strings (`@"`, `$"`), Kotlin strings containing `$`, Python + f-strings, and any string that runs to the end of a line; +- in JS/TS, any `/` outside a comment (division and regex literals cannot be + told apart), JSX-like ``, ``; +- a line comment ending in `\` (it continues onto the next line in C and + Make), the trigraph `??/`, a `/*` inside a block comment, and an + unterminated block comment or string; +- a code line ending in a line continuation `\` (trailing blanks included): + a C macro, a Python explicit continuation or a string continued onto the + next line joins that line, so adding or removing a comment-only line after + it changes code. + +## Directive comments + +Some comments are read by the language, the build or a tool, so their text is +code. A directive comment is kept in the compared code verbatim: changing, +adding or removing one makes the entry non-trivial, while an unchanged +directive next to an edited ordinary comment does not. + +- A comment whose text starts with `!` (shebangs, Rust inner docs, `/*!`), + `/` (`///` doc comments and TypeScript triple-slash references), `go:`, + `export` or `extern` followed by a blank (cgo), or `line` followed by a + blank (Go line directives), with no blank after the comment marker. +- A comment whose first word, after blanks, `*` and `/`, starts with `@`, `#`, + `<`, `+`, `!`, `type:` or `requires`, or is `global`, `globals` or + `exported` followed by a blank + (JSDoc and TypeScript pragmas, `//# sourceMappingURL`, `// +build`, Python + type comments, ESLint globals, PowerShell `#Requires`). +- A comment containing a tool or encoding marker such as `lint`, `ts-`, + `noqa`, `nosec`, `pragma`, `coding:`, `fmt:`, `istanbul`, `prettier-`, + `webpack`, `__PURE__`, `fallthrough`, `shellcheck`, `suppress`, `sonar`, + `gitleaks`, `allowlist`, `vim:`, `-*-`, `DO NOT EDIT`, `#compdef` or Go's + example `// Output:`, or a JSDoc type + (`@` together with `{`). The list is in `DIRECTIVE_WORDS`; matching is + case-insensitive and substring-based, so it over-matches prose that happens + to contain a marker, which only keeps an edit gated. +- Every Rust doc comment (`///`, `//!`, `/**`, `/*!`): doc tests compile and + run. + +Suppression markers (`nosec`, `NOSONAR`, `gitleaks:allow`, +`pragma: allowlist secret`, `eslint-disable`) matter most: removing a finding +from a security scanner is not a comment edit. + +## Shell scripts + +Shell comments are lexed by their own rules, and the lexer gives up (the entry +is not trivial) wherever a comment could be code: + +- POSIX shells: `#` starts a comment only at the start of a line or after a + space, tab or `;`; after a letter, `$`, `{`, `=` and the like it is a word + character (`a#b`, `$#`, `${#x}`, `${x#y}`). After `(`, `)`, `|`, `&`, `<` or + `>` the entry is not trivial (zsh glob flags such as `(#i)`). Single quotes + are raw and must close on the line; `$'...'` is not trivial; double quotes + may hold `\` escapes and a `${...}` without quotes, but `$(` inside them, + any backtick, any `<<` (heredocs, here-strings, shifts), a + backslash before a line break, and a lone carriage return (bash reads it + as a word character) make the entry not trivial. Only spaces and tabs + between words are folded; `\` escapes stay code. +- PowerShell: `#` and `<# ... #>` are comments only at the start of a line or + after a space, tab or `;`; elsewhere the entry is not trivial. `#Requires` + and `#!` are [directive comments](#directive-comments), as in every + language. Here-strings (`@"`, `@'`), typographic + quotes (PowerShell accepts them as quote marks), `$(` inside a double-quoted + string, a backtick before a line break, and a nested `<#` are not trivial. +- Batch: only `REM` lines (after optional blanks and `@`, followed by a blank + or the end of the line) are comments; `::` labels are code, since they + change the parser's behaviour inside blocks. A `REM` line holding `%`, `^`, + `&`, `|`, `<`, `>`, `(` or `)`, and any line ending in `^`, are not trivial. + Code lines are compared exactly: `echo` keeps its spacing. + +Write is never trivial. In the hook, a trivial Edit (or a MultiEdit whose +entries for that file are all trivial) of an unchecked code, test or prose +target passes with an `additionalContext` note after prior-search credit and +before sibling collapse and the denial cap. It is not marked checked and does +not touch the denial count or ordinal, so the next change that alters code is +gated as a first touch; `trivial_allows` counts the passes (merged by maximum +like the other counters). The trivial pass never marks the target checked and +never applies to sensitive, hard-linked, instruction or config targets or to +a NotebookEdit, so the next +non-trivial change still meets the full gate. + +## File context + +A snippet alone cannot show whether a comment-looking line is a comment: it +may sit inside a template literal, a docstring, a raw string or a heredoc +that opens above it, follow a line that continues onto it, or lose its line +break so the next line joins it. So an Edit is trivial only when checked +against the file it applies to. + +- The hook reads the current target (never a sensitive or hard-linked one) itself: the path + is resolved like every other target, opened read-only and non-blocking, + and used only if `fstat` says it is a regular file of at most 1 MiB; CRLF + is folded to LF, as the Edit tool does. A missing, unreadable, larger or + special file (directory, FIFO, device) gives no file text and the edit is + not trivial. The text is never logged, stored or put in a message. +- Each entry is applied in order, as the tool applies it, to the evolving + text. `old_string` must be non-empty and occur exactly once, or at least + once with `replace_all`; otherwise the tool would fail and the entry is not + trivial. Over 1 MiB of text after an edit, more than 8 MiB of scanning for + one call, or an edit window over 128 KiB is not trivial.

Here-strings (`@"`, `@'`), typographic - quotes (PowerShell accepts them as quote marks), `$(` inside a double-quoted - string, a backtick before a line break, and a nested `<#` are not trivial. -- Batch: only `REM` lines (after optional blanks and `@`, followed by a blank - or the end of the line) are comments; `::` labels are code, since they - change the parser's behaviour inside blocks. A `REM` line holding `%`, `^`, - `&`, `|`, `<`, `>`, `(` or `)`, and any line ending in `^`, are not trivial. - Code lines are compared exactly: `echo` keeps its spacing. - -Write is never trivial. In the hook, a trivial Edit (or a MultiEdit whose -entries for that file are all trivial) of an unchecked code, test or prose -target passes with an `additionalContext` note after prior-search credit and -before sibling collapse and the denial cap.
