Codex Ecosystem Setup Skill

This skill handles bootstrap and MCP management for Codex projects.

Bootstrap policy

Do not create or modify .codex/ automatically on plugin activation.

Use this policy:

Check whether .codex/config.toml exists.
If missing, explain what will be created.
Ask for confirmation.
Create files only after confirmation.

Bootstrap actions

When approved by the user:

mkdir -p .codex
cp "${CLAUDE_PLUGIN_ROOT}/.codex/config.template.toml" .codex/config.toml
cp "${CLAUDE_PLUGIN_ROOT}/.codex/recommended-mcps.toml" .codex/recommended-mcps.toml

If plugin-root files are unavailable, create .codex/config.toml with safe defaults:

model = "gpt-5.4"
model_reasoning_effort = "xhigh"
sandbox_mode = "workspace-write"
approval_policy = "on-request"

Curated MCP set

Only the verified set is considered curated here:

context7
playwright
postgres
filesystem
github

All are disabled by default in template config.

MCP enablement workflow

Analyze task requirements.
Suggest relevant MCP(s).
Ask before changing .codex/config.toml.
Enable only requested MCP(s).
Remind about required environment variables.

Notes

Prefer minimal enablement.
Use recommended-mcps.toml for server reference blocks.
For non-curated MCPs, use /codex-mcp-search and manual user confirmation.
