plugins/ecc — Legacy Codex Thin-Plugin Artifact

This directory is retained as a legacy compatibility artifact. The current .agents/plugins/marketplace.json points at the self-contained repository root, which Codex 0.146.0 accepts and copies with all referenced runtime content. Do not point the active marketplace back at this thin directory: its parent-relative references are valid in a checkout but escape the isolated plugin cache after installation.

Single source of truth

Per the repo's no-duplication policy, no skill or MCP content is vendored here. .codex-plugin/plugin.json references the canonical root content with parent-relative paths:

Manifest fieldResolves to
skillsskills/ at the repo root
mcpServers.mcp.json at the repo root
interface.composerIcon / interface.logoassets/ at the repo root

The canonical Codex plugin manifest for the repo-root bundle (used by the official openai/plugins directory shape and other harness tooling) remains at .codex-plugin/plugin.json. Keep name and version in both manifests in sync — tests/plugin-manifest.test.js enforces this and scripts/release.sh bumps both.

Current Codex plugin-mode status

The native marketplace now installs from the repository root. A fresh Codex 0.146.0 cache contains the configure skill, shared skills, MCP configuration, hooks, scripts, and assets, and an authenticated session loads the configure-ecc skill without hook failures.

After install, codex plugin list is not enough to prove the runtime can load the referenced skills and assets. From an ECC checkout, run:

bash
node scripts/codex/check-plugin-cache.js

The check inspects the installed cache under CODEX_HOME (or ~/.codex) and fails if .codex-plugin/plugin.json points at files that were not copied into that cache entry.

The manual sync flow remains available only as a separate legacy compatibility path when copied/merged home configuration is explicitly desired:

bash
npm install && bash scripts/sync-ecc-to-codex.sh
