# .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
