Chris Yau 09efd68228 fix: safe Codex config sync — merge AGENTS.md + add-only MCP servers (#723)
* fix: replace bash TOML surgery with Node add-only MCP merge

The old sync script used awk/sed to remove and re-append MCP server
sections in config.toml, causing credential extraction races, duplicate
TOML tables, and 3 fragile code paths with 9 remove_section_inplace
calls each.

Replace with a Node script (scripts/codex/merge-mcp-config.js) that
uses @iarna/toml to parse the config, then appends only missing ECC
servers — preserving all existing content byte-for-byte. Warns on
config drift, supports legacy aliases (context7 → context7-mcp), and
adds --update-mcp flag for explicit refresh.

* fix: address PR #723 review findings for Codex MCP merge

- Use package-manager abstraction (scripts/lib/package-manager.js)
  instead of hardcoding pnpm — respects CLAUDE_PACKAGE_MANAGER,
  lock files, and project config
- Add Yarn 1.x fallback to npx (yarn dlx unsupported in classic)
- Add missing exa server to match .codex/config.toml baseline
- Wire up findSubSections for --update-mcp nested subtable removal
  (fixes Greptile P1: Object.keys only returned top-level keys)
- Fix resolvedLabel to prefer canonical entry over legacy alias
  when both exist (fixes context7/context7-mcp spurious warning)
- Fix removeSectionFromText to handle inline TOML comments
- Fix dry-run + --update-mcp to show removals before early return
- Update README parity table: 4 → 7 servers, TOML-parser-based
- Add non-npm install variants to README Codex quick start
- Update package-lock.json for @iarna/toml

* fix: address PR #723 review comments (preflight, marker validation)

- Add Node.js and merge-mcp-config.js to preflight checks so the
  script fails fast before partial writes (CodeRabbit)
- Validate marker counts: require exactly 1 BEGIN + 1 END in correct
  order for clean replacement (CodeRabbit)
- Corrupted markers: strip all marker lines and re-append fresh block,
  preserving user content outside markers instead of overwriting
- Move MCP_MERGE_SCRIPT to preflight section, remove duplicate

# ECC for Codex CLI
This supplements the root `AGENTS.md` with Codex-specific guidance.
## Model Recommendations
| Task Type | Recommended Model |
|-----------|------------------|
| Routine coding, tests, formatting | GPT 5.4 |
| Complex features, architecture | GPT 5.4 |
| Debugging, refactoring | GPT 5.4 |
| Security review | GPT 5.4 |
## Skills Discovery
Skills are auto-loaded from `.agents/skills/`. Each skill contains:
- `SKILL.md` — Detailed instructions and workflow

- security-review — Comprehensive security checklist
- coding-standards — Universal coding standards
- frontend-patterns — React/Next.js patterns
- frontend-slides — Viewport-safe HTML presentations and PPTX-to-web conversion
- article-writing — Long-form writing from notes and voice references
- content-engine — Platform-native social content and repurposing
- market-research — Source-attributed market and competitor research
- investor-materials — Decks, memos, models, and one-pagers

- crosspost — Multi-platform content distribution
- fal-ai-media — AI image/video/audio generation via fal.ai
- dmux-workflows — Multi-agent orchestration with dmux
## MCP Servers
Treat the project-local `.codex/config.toml` as the default Codex baseline for ECC. The current ECC baseline enables GitHub, Context7, Exa, Memory, Playwright, and Sequential Thinking; add heavier extras in `~/.codex/config.toml` only when a task actually needs them.
### Automatic config.toml merging
The sync script (`scripts/sync-ecc-to-codex.sh`) uses a Node-based TOML parser to safely merge ECC MCP servers into `~/.codex/config.toml`:
- **Add-only by default** — missing ECC servers are appended; existing servers are never modified or removed.
- **7 managed servers** — Supabase, Playwright, Context7, Exa, GitHub, Memory, Sequential Thinking.
- **Package-manager aware** — uses the project's configured package manager (npm/pnpm/yarn/bun) instead of hardcoding `pnpm`.
- **Drift warnings** — if an existing server's config differs from the ECC recommendation, the script logs a warning.
- **`--update-mcp`** — explicitly replaces all ECC-managed servers with the latest recommended config (safely removes subtables like `[mcp_servers.supabase.env]`).
- **User config is always preserved** — custom servers, args, env vars, and credentials outside ECC-managed sections are never touched.
## Multi-Agent Support
Codex now supports multi-agent workflows behind the experimental `features.multi_agent` flag.
- Enable it in `.codex/config.toml` with `[features] multi_agent = true`
- Define project-local roles under `[agents.<name>]`
- Point each role at a TOML layer under `.codex/agents/`
- Use `/agent` inside Codex CLI to inspect and steer child agents
Sample role configs in this repo:
- `.codex/agents/explorer.toml` — read-only evidence gathering
- `.codex/agents/reviewer.toml` — correctness/security review
- `.codex/agents/docs-researcher.toml` — API and release-note verification
## Key Differences from Claude Code
| Feature | Claude Code | Codex CLI |
|---------|------------|-----------|
| Hooks | 8+ event types | Not yet supported |
| Context file | CLAUDE.md + AGENTS.md | AGENTS.md only |
| Skills | Skills loaded via plugin | `.agents/skills/` directory |
| Commands | `/slash` commands | Instruction-based |
| Agents | Subagent Task tool | Multi-agent via `/agent` and `[agents.<name>]` roles |
| Security | Hook-based enforcement | Instruction + sandbox |
| MCP | Full support | Supported via `config.toml` and `codex mcp add` |
## Security Without Hooks
Since Codex lacks hooks, security enforcement is instruction-based:
1. Always validate inputs at system boundaries
2. Never hardcode secrets — use environment variables
3. Run `npm audit` / `pip audit` before committing
4. Review `git diff` before every push
5. Use `sandbox_mode = "workspace-write"` in config
