ECC/CHANGELOG.md

Changelog

Unreleased

Changed

• Default MCP connector set reduced to a single connector (chrome-devtools) per the new connector policy (docs/MCP-CONNECTOR-POLICY.md). The six previous defaults (github, context7, exa, memory, playwright, sequential-thinking) were retired after the June 2026 audit: their jobs are covered by skills wrapping CLIs/REST APIs (github-ops, documentation-lookup, exa-search, e2e skills) or by harness-native features (memory, extended thinking, web search). All six remain opt-in via mcp-configs/mcp-servers.json.

Fixed

• ecc memory writes and --body-file reads failed on Windows under Node 22.12-22.16 and 24.0-24.1. libuv resolved path-based stat()/lstat() through GetFileInformationByName without setting the volume serial, while fstat() reported it, so the memory vault's TOCTOU guard rejected every operation. Fixed upstream in libuv 1.51.0; the guard no longer depends on the runtime's patch level. The guard's stat calls now request BigInt values, so Windows file IDs past Number.MAX_SAFE_INTEGER can no longer collapse two distinct files into one identity.

2.0.0 - 2026-06-09

Added

• Discord community launch: server + GitHub PR/issue/release feed, release-announce.yml workflow (announce + pin + Discussions cross-post), and a dependency-free community bot (scripts/discord/ecc-bot.mjs) with /ecc, /help, /skill, /docs, /release.
• orch-* orchestrator skill family and dynamic workflow team orchestration.
• kubernetes-patterns skill, worktree-lifecycle service, MCP inventory (ecc.mcp.v1), codex-worktree and opencode session adapters.

Fixed

• Plugin hooks silently no-oped on Node 21+ (require.main undefined under node -e).
• Windows reliability: CLAUDE_PLUGIN_ROOT normalization, stdin prompt passing, symlink/chmod test guards.
• Session-end $-sequence corruption, project-detect boundary matching, install manifest gaps, corrupted legacy shim truncation.

Changed

• Version graduated to 2.0.0 stable across package, plugin, marketplace, OpenCode, and agent metadata.
• Smaller default OpenCode install surface; rules/zh removed from the always-loaded default install.

2.0.0-rc.1 - 2026-04-28

Highlights

• Adds the public ECC 2.0 release-candidate surface for the Hermes operator story.
• Documents ECC as the reusable cross-harness substrate across Claude Code, Codex, Cursor, OpenCode, and Gemini.
• Adds a sanitized Hermes import skill surface instead of publishing private operator state.

Release Surface

• Updated package, plugin, marketplace, OpenCode, agent, and README metadata to 2.0.0-rc.1.
• Added docs/releases/2.0.0-rc.1/ with release notes, social drafts, launch checklist, handoff notes, and demo prompts.
• Added docs/architecture/cross-harness.md and regression coverage for the ECC/Hermes boundary.
• Kept ecc2/ versioning independent for now; it remains an alpha control-plane scaffold unless release engineering decides otherwise.

Notes

• This is a release candidate, not a GA claim for the full ECC 2.0 control-plane roadmap.
• Prerelease npm publishing should use the next dist-tag unless release engineering explicitly chooses otherwise.

1.10.0 - 2026-04-05

Highlights

• Public release surface synced to the live repo after multiple weeks of OSS growth and backlog merges.
• Operator workflow lane expanded with voice, graph-ranking, billing, workspace, and outbound skills.
• Media generation lane expanded with Manim and Remotion-first launch tooling.
• ECC 2.0 alpha control-plane binary now builds locally from ecc2/ and exposes the first usable CLI/TUI surface.

Release Surface

• Updated plugin, marketplace, Codex, OpenCode, and agent metadata to 1.10.0.
• Synced published counts to the live OSS surface: 38 agents, 156 skills, 72 commands.
• Refreshed top-level install-facing docs and marketplace descriptions to match current repo state.

New Workflow Lanes

• brand-voice — canonical source-derived writing-style system.
• social-graph-ranker — weighted warm-intro graph ranking primitive.
• connections-optimizer — network pruning/addition workflow on top of graph ranking.
• customer-billing-ops, google-workspace-ops, project-flow-ops, workspace-surface-audit.
• manim-video, remotion-video-creation, nestjs-patterns.

ECC 2.0 Alpha

• cargo build --manifest-path ecc2/Cargo.toml passes on the repository baseline.
• ecc-tui currently exposes dashboard, start, sessions, status, stop, resume, and daemon.
• The alpha is real and usable for local experimentation, but the broader control-plane roadmap remains incomplete and should not be treated as GA.

Notes

• The Claude plugin remains limited by platform-level rules distribution constraints; the selective install / OSS path is still the most reliable full install.
• This release is a repo-surface correction and ecosystem sync, not a claim that the full ECC 2.0 roadmap is complete.

1.9.0 - 2026-03-20

Highlights

• Language coverage expanded to 10+ ecosystems with 6 new agents and language-specific rules.
