New extension workflow:

1. Choose the clients and open formats you support
2. Build the plugin, skill, MCP server, app, or agent tool
3. Validate with plugin-scanner — recommended local preflight
4. Add the HOL scanner GitHub Action — recommended for security, optional for listing
5. Ship or submit with confidence

Quick preflight

pipx run plugin-scanner lint .
pipx run plugin-scanner verify .

Scanner CI (recommended for security)

Scanner CI is optional for listing. HOL still scans listed projects independently. We recommend including it so MCP servers, skills, plugins, and other agent extensions stay continuously checked — that is how this catalog stays safer for everyone who installs from it. Projects that maintain scanner CI receive the full trust score; projects without it remain eligible and receive a 10% trust-score reduction.

See the full guide: SCANNER_GUIDE.md See contributing requirements: CONTRIBUTING.md

The README is the human-readable cross-platform catalog. Machine-readable compatibility exports are available in plugins.json and .agents/plugins/marketplace.json for registry and automation consumers.

• Codex Process Jobs - Run long local builds, tests, benchmarks, and inference jobs as durable detached processes with tracked status, bounded results, and completion delivery across Codex surfaces.
• Codex Reviewer - Second-pass review of Claude-driven plans and implementations.
• Codex rg Guard - Budgeted rg/grep replacement for Codex that narrows broad searches before they waste model context.
• Codex Skin Pack Installer - Codex plugin and skill that stages verified desktop skin packs from GitHub releases, validates files, and keeps restore guidance visible.
• Codex Subagent Playbook - Routes subagent work using model and reasoning-effort defaults tuned through measured comparisons and daily Codex use: stronger models handle judgment-heavy research and review, lower-cost models execute well-specified plans, and Codex uses longer waits to avoid frequent polling, intervenes on stalls, and verifies results.
• Codex Token Watch - Read-only macOS CLI that turns local Codex Desktop task logs into per-turn token, prompt-cache, cache-miss, duration, and API-cost analysis.
• Codex TUI Proof - Visually validate real local terminal UIs in Codex's in-app browser with screenshots and session evidence.
• Codex Usage and Resets - Turns Codex usage into planning facts with linear pace, projected exhaustion, banked-reset expirations, and conservative unexpected-reset detection.
• Codex × Grok Bot Task Bridge - MCP task bridge for queued, read-only research between Codex and Grok Bot, with fenced leases, idempotency, scoped OAuth, evidence-based results, and optional Codex-side continuation.
• codex-autoresearch - Codex plugin that runs measured optimization loops against a benchmark to improve local code.
• codex-profiles - Switch Codex CLI and Desktop accounts with isolated CODEX_HOME profile directories instead of copying token files.
• coffee-paladin - Thermal guard for Apple Silicon: pauses hot jobs before the Mac throttles and gates Claude Code, Codex and Gemini CLI before heavy commands.
• Commit Narrator - Generate semantic commit message from staged diff, including the _why_.
• CommitLore - Keeps const
