claude-plugin-marketplace

Central marketplace for Claude Code and OpenAI Codex CLI plugins by xiaolai.

Two manifest files live in this repo:

• .claude-plugin/marketplace.json — Claude Code entries (read by claude plugin install)
• .agents/plugins/marketplace.json — Codex CLI entries (read by codex plugin install)

Each plugin repo can ship both layouts in parallel: .claude-plugin/ for Claude Code, .codex-plugin/ + codex/ tree for Codex. The two ecosystems coexist in one source repo per plugin.

Installation

For Claude Code:

claude plugin marketplace add xiaolai/claude-plugin-marketplace

For Codex CLI:

codex plugin marketplace add xiaolai/claude-plugin-marketplace

Available Plugins (Claude Code)

Plugin	Description	Version
cc-suite	CC Suite — one plugin to bridge and delegate across Claude Code, Codex CLI, and Gemini CLI: single-source AGENTS.md, shared skills, mirrored hooks and MCP servers, full Claude↔Codex bidirectional delegation (including Codex reading Claude's session history), plus project-scoped advisor agents (value-over-rules personas). Supersedes cc-bridge and codex-toolkit.	0.8.0
tdd-guardian	TDD Guardian — test-first workflow, coverage gates, mutation testing, test quality audits	0.7.2
echo-sleuth	Echo Sleuth — mine past conversations, manage memory lifecycle, extract knowledge	0.4.0
loc-guardian	LOC Guardian — enforce per-file pure LOC limits with automated optimization strategies	0.1.5
grill	Grill — deep codebase interrogation with 6 specialized agents, 5 review styles, and 8 add-on pressure tests	1.3.0
docs-guardian	Docs Guardian — documentation quality and freshness enforcer with staleness detection, accuracy checking, and auto-generation	0.1.8
nlpm	NLPM — score, check, fix, and test NL artifacts across Claude Code, Codex CLI, and Antigravity; tier-aware scoring with per-tool overlays (universal nlpm:conventions floor + conventions-claude, conventions-codex, conventions-antigravity overlays); per-tool Hooks tables (the three event vocabularies aren't 1:1 mappable); standalone Python validator (bin/nlpm-check) remains tool-agnostic for pre-commit hooks and CI; manifest-vs-disk consistency check still the differentiator in the Claude ecosystem	1.1.0
claude-english-buddy	English language coach — auto-corrects prompts, translates non-English, tracks improvement over time	0.5.1
mermaid-preview	Mermaid Preview — auto-preview diagrams in the browser on Write/Edit, offline-safe, dark-mode aware; opens the tab once per file	0.1.4
ui-tokenize	UI Tokenize — block hardcoded UI values; rewrite-first PreToolUse hook corrects literals to design-token references on the way to disk; configurable strict / advisory strictness; per-project surfaces allowlist narrows scanning; /tokenize:review dispatches the token-reviewer agent for semantic mis-pick review	0.4.0
ui-responsive	UI Responsive — advisory responsive-design coach; flags off-catalog breakpoints, bare 100vh, fixed widths without max-width via PostToolUse additionalContext	0.1.0
north-star	North Star — 260-token system prompt overriding three RLHF-inherited presumptions (independence, calibration, first-principles); ambient + slash command + subagent layered delivery	0.1.1
anthropic-docs	Auto-updated Anthropic docs — 8 skills covering claude-code, claude-agent-sdk, anthropic-api, anthropic-platform-features, claude-connectors, claude-cowork, mcp-spec, plus anthropic-pulse (news + research digest); GitHub Actions pipeline refreshes daily from upstream docs + HTML feeds; supersedes the archived single-skill predecessor claude-agent-sdk-skill-autoupdated	1.0.0
eou-foundry	EOU Foundry — recursive governance for Executable Operating Units (EOUs): faceted classification, generating-EOU constraints, ECP-governed change, no-self-approval. 12 skills covering candidate generation, audit, specify, refactor, promote, foundry-wide audit, ECP authoring, init scaffolding, Stage 0 capture, and judgment audit.	0.8.1
bureau	Bureau — turn AI sessions into a maintained, human-reviewed knowledge base: capture → compile → review → query, gated by trust tiers (proposed → verified → canonical), with a BUREAU.md instruction (imported by CLAUDE.md) that makes every session honor them; renders to an offline gazette (built by the bundled press), and enables a crew of specialized agents. Ships an AI-facing guide skill that orients any session to the model, the gate, and the right command, plus a localhost chamber (bureau:serve) for interactive intake + a token-gated review surface. Authors get tabbed content in the gazette. Self-contained.	0.5.2
cc-bridge	DEPRECATED — use cc-suite instead	0.1.0

Available Plugins (Codex CLI)

Codex ports are added incrementally as each plugin is converted. Status table — entries are removed from "pending" and added here once their .codex-plugin/ and codex/skills/ artifacts are committed and smoke-tested.

Plugin	Description	Version	Status
grill	Grill — deep codebase interrogation with 7 specialized analysis skills, 5 review styles, and 8 add-on pressure tests	1.3.0	Layout committed; install-side smoke test pending
eou-foundry	EOU Foundry — turn messy workflows into auditable Executable Operating Units with recursive governance (12 skills: candidate generation, audit, specify, refactor, promote, foundry-wide audit, ECP authoring, init scaffolding, Stage 0 capture, judgment audit). v0.7.0 ships Stage 0 (captured_workflow + per-app domain_values constitutional layer + Rule 96 consumption). v0.8.0 ships agentic judgment (judgment_authorized flag, value_invocations trace, F14–F17 taxonomy, judgment_maturity J0–J4 axis, $audit-judgment skill, Rule 97, counterfactual-swap audit).	0.8.1
nlpm	NLPM — reference-knowledge skills (17): the 50 Rules, the 100-point scoring rubric, per-tool conventions (Claude Code / Codex CLI / Antigravity), anti-patterns, vocabulary discipline, and authoring guides. Knowledge skills, not commands — $nlpm-rules + $nlpm-scoring to score an artifact, $nlpm-conventions-codex for the Codex layout. The interactive /nlpm:* linting commands stay a Claude Code plugin (they orchestrate sub-agents); cross-tool deterministic checks use the standalone bin/nlpm-check.	1.1.0	Reference-knowledge port; the command/agent orchestration stays Claude-only by design

Pending ports: tdd-guardian, loc-guardian, docs-guardian, echo-sleuth, claude-english-buddy. The Claude↔Codex delegation lane is now handled by cc-suite (single plugin, bidirectional). codex-guardian (Codex-artifact auditor) remains a planned future addition for the Codex-only audit niche.

Codex installs

Codex installs plugins from a marketplace via the in-session /plugins TUI, not a shell command. The shell codex plugin subcommand only manages marketplaces (no install verb exists).

One-time setup (shell):

codex plugin marketplace add xiaolai/claude-plugin-marketplace

Codex registers this as marketplace name xiaolai (flattened from the GitHub URL — the name field inside .agents/plugins/marketplace.json is ignored at registration).

Per-plugin install (inside a Codex session):

1. Start a session: codex (in your project directory)
2. Type /plugins — opens the plugin TUI
3. Find grill in the xiaolai marketplace, install/enable it

Invoking a plugin (inside a Codex session):

Codex uses the skill prefix $, not slash commands. Type:

$grill-roast

Or just describe the task in natural language ("do a multi-angle audit of this codebase") and Codex's auto-match will load the skill from its description.

(More entries to come as Codex ports land.)

Managing Plugins

claude plugin list                           # List installed plugins
claude plugin update grill@xiaolai           # Update to latest version
claude plugin disable grill@xiaolai          # Temporarily disable
claude plugin enable grill@xiaolai           # Re-enable
claude plugin uninstall grill@xiaolai        # Remove

Troubleshooting

plugin install says "Plugin not found in marketplace 'xiaolai'"

The marketplace is a local git clone, and claude plugin install does not auto-refresh it before resolving the plugin name. If a plugin was added to the marketplace after your local clone was last updated, install will fail with a misleading "not found" error.

Refresh the marketplace, then retry:

claude plugin marketplace update xiaolai
claude plugin install <plugin-name>@xiaolai --scope user

This is a Claude Code CLI limitation, not a marketplace configuration issue. The plugin is genuinely listed in marketplace.json; your local copy is just stale.
