Lockfile is `bun.lock` (text) by default in current Bun; older versions used `bun.lockb` (binary). +- **Version baseline**: guidance below targets Bun 1.4.x. Check the actual version with `bun --version` before relying on flag names, since CLI flags can change between releases. +- **Runtime**: Drop-in Node-compatible runtime, built on JavaScriptCore. As of Bun 1.4 the runtime itself is implemented in Rust (migrated from Zig). Not 100% Node-compatible — some native addons, less-common `node:` internal APIs, and packages that depend on Node-specific internals can still fail; verify before depending on it in production. +- **Package manager**: Bun includes a package manager; installation performance depends on the project, network conditions, and cache state. Lockfile is `bun.lock` (text) by default in current Bun; older versions used `bun.lockb` (binary) — Bun still reads that format for migration, but new projects should use `bun.lock`. - **Bundler**: Built-in bundler and transpiler for apps and libraries. -- **Test runner**: Built-in `bun test` with Jest-like API. +- **Test runner**: Built-in `bun test` with a Jest-like API. **Migration from Node**: Replace `node script.js` with `bun run script.js` or `bun script.js`. Run `bun install` in place of `npm install`; most packages work. Use `bun run` for npm scripts; `bun x` for npx-style one-off runs. Node built-ins are supported; prefer Bun APIs where they exist for better performance. -**Vercel**: Set runtime to Bun in project settings. Build: `bun run build` or `bun build ./src/index.ts --outdir=dist`. Install: `bun install --frozen-lockfile` for reproducible deploys. +**Package and workspace commands**: `bun add ` / `bun remove ` / `bun update [pkg]` manage dependencies; `bun outdated` lists stale deps. `bun pm ls` lists project dependencies and resolved versions using the lockfile; `--all` includes transitive dependencies. It is not an integrity check of installed file contents. [`bun audit`](https://bun.com/docs/pm/cli/audit) queries registry advisories using package names and versions from `bun.lock`; it does not modify `package.json`, `bun.lock`, or `node_modules`. Review approved destinations before sending private package metadata. Packages whose scoped registry lacks an advisory endpoint are skipped and do not affect the exit code. `bun audit fix` upgrades and installs dependencies, changing the lockfile and installed packages and sometimes direct version pins; review it as a modifying install operation, including applicable lifecycle scripts. `bun dedupe` collapses duplicate installs, and `bun prune` removes packages no longer referenced. Monorepos use a root `workspaces` array in `package.json` (same convention as npm/yarn); run a script in one workspace with `bun run --filter + `; /* eslint-enable no-useless-escape */ } @@ -831,6 +931,43 @@ function sendHtml(res, statusCode, html) { res.end(html);

Validate Identifiers, Environment Values, and URLs + +Use an allowlist for identifiers that become filenames, keys, selectors, or command arguments. Agent IDs have the issue-defined hard maximum of 64 characters; deployment configuration may choose a stricter positive limit but cannot raise that boundary: + +```python +import re + +SAFE_AGENT_ID_CHARS = re.compile(r"^[A-Za-z0-9_][A-Za-z0-9_-]*$") +HARD_MAX_AGENT_ID_LENGTH = 64 + +def require_agent_id(value: object, *, max_length: int) -> str: + if ( + isinstance(max_length, bool) + or not isinstance(max_length, int) + or not 1 <= max_length <= HARD_MAX_AGENT_ID_LENGTH + ): + raise RuntimeError("configured agent ID limit must be between 1 and 64") + if ( + not isinstance(value, str) + or len(value) > max_length + or not SAFE_AGENT_ID_CHARS.fullmatch(value) + ): + raise ValueError("invalid agent identifier") + return value +``` + +When an identifier becomes a CLI argument, pass it through an argv API and place it after the command's end-of-options marker where supported.

For every outbound connection and redirect hop, pin the connection to a validated public address or verify the connected peer address at connection time so DNS rebinding cannot cross the boundary. A credential-bearing request must use HTTPS with certificate verification before credentials are attached.

Re-run destination, connected-address, and transport validation on every hop. + +This step is complete when tests reject empty, oversized, malformed, traversal-shaped, credential-bearing, and unauthorized-destination values before any side effect, and prove that DNS rebinding and cross-origin redirects cannot carry credentials to an unapproved peer. + +### 3. Contain Filesystem Access + +Reject absolute user-controlled paths and traversal components before joining. Reject Windows-unsafe components on every platform so behavior stays portable: reserved device names (`CON`, `NUL`, `COM1`, `LPT1`, including with an extension such as `nul.txt`), names ending in a dot or space (Win32 strips them), and `:` (drive-relative or NTFS alternate data stream syntax such as `report.txt:ads`).

For sensitive writes, open relative to a trusted directory handle where the platform supports it, reject symlink targets, create files exclusively, and verify ownership and permissions after opening. + +This step is complete when tests cover sibling-prefix paths, nested `..`, absolute paths, symlink escapes, reserved device names, trailing dots or spaces, alternate data stream syntax, and a valid nested workspace path. + +### 4. Protect Temporary Data and Credentials + +- Create sensitive files with owner-only permissions such as `0o600`; create private directories with `0o700`. +- Prefer a user-private runtime directory over a shared temporary directory for credentials or tenant data. +- Create unpredictable names atomically; do not check-then-create. +- Remove temporary data in `finally`, while preserving a redacted error record when cleanup fails. +- Keep secrets out of command arguments, model context, logs, traces, exception text, and tool responses. +- Pass secrets through the platform's secret store or scoped environment injection and rotate exposed credentials. +- Treat zeroization as best effort: mutable byte buffers can be overwritten, but immutable language strings cannot be reliably erased. + +This step is complete when file-mode checks, forced-error cleanup tests, and log-capture tests show that secret values never persist outside the approved boundary. + +### 5. Bound and Sanitize Tool Output + +Read tool output with a byte limit rather than collecting an unbounded stream. Preserve structured fields, remove disallowed control characters, and append an explicit truncation marker with the original byte count. Keep a content hash when later forensic comparison matters. + +Do not silently turn malformed output into an empty success value. Return a typed failure that names the producing tool, boundary, and validation reason without echoing sensitive content. + +This step is complete when oversized output, invalid encoding, terminal-control sequences, malformed structured data, and a normal response all have deterministic tests. + +## Verification Gate + +Before calling the framework hardened, verify all of these behaviors through its real entry point: + +1. Untrusted instructions remain data and cannot trigger a tool or write. +2. An irreversible action without operation-and-resource authorization plus confirmation or scoped pre-approval leaves no side effect. +3. Cross-tenant and cross-workspace identifiers are rejected at the action boundary. +4. Traversal and symlink escape attempts leave the filesystem unchanged. +5. Forced failures leave no credential-bearing temp files or logs. +6. Oversized or malformed tool output returns an explicit bounded error. + +Report the command used, exit status, rejected input, and observed absence of the side effect. Mock-only tests do not prove operating-system permissions, symlink handling, subprocess isolation, or network egress controls. + +## Common Issues + +### Validation exists only in the prompt + +Prompt instructions are advisory. Move the same invariant into deterministic code immediately before the side effect and test a model response that violates it. + +### A normalized path still escapes + +String prefix checks confuse sibling paths such as `/work/app` and `/work/application`.

[`bun audit`](https://bun.com/docs/pm/cli/audit) queries registry advisories using package names and versions from `bun.lock`; it does not modify `package.json`, `bun.lock`, or `node_modules`. Review approved destinations before sending private package metadata. Packages whose scoped registry lacks an advisory endpoint are skipped and do not affect the exit code. `bun audit fix` upgrades and installs dependencies, changing the lockfile and installed packages and sometimes direct version pins; review it as a modifying install operation, including applicable lifecycle scripts. `bun dedupe` collapses duplicate installs, and `bun prune` removes packages no longer referenced. Monorepos use a root `workspaces` array in `package.json` (same convention as npm/yarn); run a script in one workspace with `bun run --filter
