# .codex-plugin — Codex Native Plugin for ECC This directory contains the **Codex plugin manifest** for ECC. ## Structure ``` .codex-plugin/ └── plugin.json — Codex plugin manifest (name, version, skills ref, MCP ref) .mcp.json — MCP server configurations at plugin root (NOT inside .codex-plugin/) ``` ## What This Provides - **249 skills** from `./skills/` — reusable Codex workflows for TDD, security, code review, architecture, and more - **6 MCP servers** — GitHub, Context7, Exa, Memory, Playwright, Sequential Thinking ## Installation Codex plugin support is marketplace-backed. The repo exposes a repo-scoped marketplace at `.agents/plugins/marketplace.json`; Codex can add and track that marketplace source from the CLI: ```bash # Add the public repo marketplace codex plugin marketplace add affaan-m/ECC # Or add a local checkout while developing codex plugin marketplace add /absolute/path/to/ECC ``` The marketplace entry points at `plugins/ecc/` — Codex does not discover plugins whose local marketplace `source.path` is the marketplace root (`./`), so the entry must target a concrete plugin subdirectory (see [#2128](https://github.com/affaan-m/ECC/issues/2128)). That thin plugin folder references the root `skills/` and `.mcp.json` so content stays single-sourced. After adding or updating the marketplace, restart Codex and install or enable `ecc` from the plugin directory. > **Plugin mode is currently fragile on Codex.** Marketplace discovery and > install work with this layout, but runtime skill loading from local/repo > marketplaces is unreliable upstream > ([openai/codex#26037](https://github.com/openai/codex/issues/26037)) — Codex > copies only the plugin folder into its install cache, so parent-referenced > content may not be exposed in a fresh session. The safer, fully supported > path today is the manual sync flow: > `npm install && bash scripts/sync-ecc-to-codex.sh`. Official Plugin Directory publishing is coming soon. For official OpenAI plugin-directory review, package this repo under the `openai/plugins` repository shape: `plugins/ecc/.codex-plugin/plugin.json`, `plugins/ecc/skills/`, and the supporting README/assets. Until that listing is accepted, treat the public repo marketplace as the supported Codex distribution path and keep release copy framed as repo-marketplace/manual installation. The installed plugin registers under the short slug `ecc` so tool and command names stay below provider length limits. ## MCP Servers Included | Server | Purpose | |---|---| | `chrome-devtools` | Interactive browser debugging via Chrome DevTools (CDP sessions, performance traces, console/network inspection) | The former defaults (`github`, `context7`, `exa`, `memory`, `playwright`, `sequential-thinking`) were retired in the June 2026 connector audit — their jobs are covered by skills wrapping CLIs/REST APIs or by harness-native features. They remain available as opt-in entries in `mcp-configs/mcp-servers.json`. See `docs/MCP-CONNECTOR-POLICY.md` for the policy and the per-connector rationale. ## Notes - The `skills/` directory at the repo root is the source of truth for the Codex plugin package; do not duplicate skill content inside `.codex-plugin/`. - ECC is moving to a skills-first workflow surface. Legacy `commands/` remain for compatibility on harnesses that still expect slash-entry shims. - MCP server credentials are inherited from the launching environment (env vars) - This manifest does **not** override `~/.codex/config.toml` settings
