Claude Night Market

A plugin marketplace for Claude Code. Install only the plugins you need to run git workflows, code review, spec-driven development, and autonomous agents from inside your Claude Code session.

Install

Requires Claude Code 2.1.16+ and Python 3.9+ for hooks.

# Add the marketplace, then install the plugins you want
/plugin marketplace add athola/claude-night-market
/plugin install sanctum@claude-night-market    # Git workflows
/plugin install pensive@claude-night-market    # Code review
/plugin install spec-kit@claude-night-market   # Spec-driven dev

Run claude --init once after installing. Two other paths exist: npx skills pulls the skill files alone into .claude/skills/, without commands, agents, or hooks, and opkg i gh@athola/claude-night-market --plugins sanctum,pensive installs whole plugins from the openpackage.yml each one ships. Full options are in the Installation Guide.

If the Skill tool is unavailable, read skill files directly at plugins/{plugin}/skills/{skill-name}/SKILL.md.

Everyday Use

Night Market is built around the loop you already work in. A typical feature runs end to end on a handful of commands:

1. Start a feature. /attune:mission routes you through brainstorm, specify, plan, and execute phases.
2. Write the code. imbue enforces a failing test first, so implementation follows the test, not the other way around.
3. Review before you push. /full-review runs a multi-discipline pass; /refine-code cleans up duplication and dead code.
4. Ship it. /prepare-pr runs quality gates and drafts a description that says who the change is for, where it lands inside and outside the codebase, and when it is fully integrated.
5. Pick up where you left off. /catchup rebuilds context from recent git history after a break.

The commands you reach for most:

Task	Command
Run the project lifecycle	/attune:mission
Initialize a new project	/attune:arch-init
Review a PR	/full-review
Address review feedback	/fix-pr
Implement an issue	/do-issue
Prepare a pull request	/prepare-pr
Write a spec	/speckit-specify
Catch up on changes	/catchup
Package project knowledge as skills	/attune:skill-library
Clean up the codebase	/unbloat
Pressure-test a decision	/attune:war-room

Full task-by-task walkthroughs are in the Common Workflows Guide.

What's Inside

23 plugins in four layers. Each installs independently, and dependencies pull their shared runtime automatically.

Foundation is the base every other layer builds on: leyline (auth, quotas, error patterns, trust verification), sanctum (git, commits, PR prep, sessions), and imbue (TDD enforcement, proof-of-work, scope guarding).

Utility handles cross-cutting concerns: conserve (context and token optimization), conjure (delegation to seven external model CLIs plus a local runner), hookify (a behavioral rules engine with a security catalog), egregore (autonomous agent orchestration), herald (notifications), and oracle (local ML inference).

Domain is where the day-to-day work happens: pensive (code and architecture review), attune (project lifecycle), spec-kit (spec-driven development), parseltongue (Python), minister (GitHub issues and DORA metrics), memory-palace (knowledge organization), archetypes (architecture paradigms), gauntlet (codebase learning), phantom (computer use), scribe (documentation and slop detection), scry (recordings), tome (research), and cartograph (codebase visualization).

Meta improves the system itself: abstract (skill authoring, hook development, evaluation, and skill-stability tracking).

The full skill, command, and agent inventory is in the Capabilities Reference.

Safety

⚠️ Plugins run inside your Claude Code session and can read or edit your repo, run shell commands, and call external services. Review any plugin before installing it.

Three guards reduce the blast radius, but none replace your own review:

• TDD gates (imbue) block implementation writes that lack a failing test.
• Destructive-command blockers (conserve, hookify) auto-approve safe commands and halt or warn on rm -rf, git push --force, and production-shaped targets.
• Additive-bias audits (leyline) flag unjustified additions before commit.

CONSTITUTION.md holds the immutable rules that override any conflicting skill or hook; STEWARDSHIP.md is the maintenance contract.

Network and data

Three parts of the marketplace reach off your machine. Each can be turned off.

Two hooks use your existing GitHub credentials, and both fail silently when gh is unauthenticated or the network is unavailable.

• Star prompt (leyline, plugins/leyline/hooks/auto-star-repo.sh). On session start it checks whether you have starred athola/claude-night-market, using your gh CLI auth or a GITHUB_TOKEN / GH_TOKEN env var. It only reads star status and asks once per session; it never stars or unstars without your consent. Opt out by setting CLAUDE_NIGHT_MARKET_NO_STAR_PROMPT=1.
• Learnings and insights posting (abstract, plugins/abstract/hooks/post_learnings_stop.py). On session stop, if ~/.claude/skills/LEARNINGS.md has content, it posts a skill-usage summary (and may promote high-severity items to issues) via your authenticated gh CLI. The target is detected at runtime: a target_repo override in ~/.claude/skills/discussions/config.json, otherwise the current repo from gh repo view. Posting defaults to on; opt out by setting auto_post_learnings to false in that config file.

The third sends the contents of your files. Delegation (conjure, also reached by attune missions and egregore pipeline steps) hands execution work to whichever external model CLI answers first, in the order Gemini, Qwen, MiniMax, GLM, Muse, Codex, OpenCode. The prompt and the file contents it carries go to that provider, under the credentials you configured for it. This runs by default. Decline it for one run with CONJURE_DELEGATION=off, or for one machine by setting "enabled": false in ~/.claude/hooks/delegation/config.json. When no provider answers, the work stays on your machine.

Requirements

• Claude Code 2.1.16+ (2.1.32+ for agent teams, 2.1.38+ for security features).
• Python 3.9+ for hooks (macOS ships 3.9.6). Hook code must stay 3.9-compatible; plugin packages may target 3.10+ via virtual environments. Working on this repo itself needs Python 3.12+, which the root pyproject.toml pins. See the Plugin Development Guide for the rules.

What's New

1.9.19 takes conjure from three delegation targets to eight and turns delegation on by default. GLM-5.3, Meta Muse Code, the OpenAI Codex CLI, OpenCode and a locally served Muse Glimmer join Gemini, Qwen and MiniMax. /conjure:provider-setup reports which of them this machine can actually call, installs the missing ones on request, and stores the answer instead of re-probing every call. Setting CONJURE_DELEGATION=off declines for a single run. Every plugin ships a workflows/ script now, so every plugin can fan work across subagents when you ask for it. Each script encodes that plugin's own fan-out: scribe runs its four document reviewers blind to each other, egregore audits each pipeline gate for whether it can return a failing verdict. A workflow only runs when you ask for one. Full history is in the CHANGELOG.

Plugin Development

make validate-all
make lint && make test

A plugin directory holds .claude-plugin/plugin.json (metadata) plus any of commands/, skills/, hooks/, agents/, workflows/, and tests/, with a Makefile and pyproject.toml. A workflows/ script orchestrates several subagents at once and runs only when you ask for one. Copy the layout from an existing plugin such as plugins/abstract, then see the Plugin Development Guide for structure and naming conventions.

Stewardship and Contributing

Every plugin is entrusted to the community: steward rather than own, and think several iterations ahead. Each plugin maintains its own tests and docs; run make test at the repo root to execute every suite, and /stewardship-health to view per-plugin health. Contribution guidelines are in the Plugin Development Guide.

Acknowledgements

Night Market builds on Anthropic Claude Code and integrates with github/spec-kit (v0.5.0), obra/superpowers (v5.0.7, see the integration guide), and three patterns adapted from QAInsights/Quillx. Per-plugin attributions are in each plugin's pyproject.toml.
