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.

Written for a practitioner: someone who already uses Claude Code and
wants to know what these plugins do and whether to install them. If you
are new to Claude Code, start with the
official docs. For the
design rationale behind a plugin, see
the book.

Install

Requires Claude Code 2.1.16+ (2.1.32+ for agent teams, 2.1.38+
for security features) and Python 3.9+ for hooks, which is what
macOS ships.

# 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 before
   the implementation is written.
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:

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, and each can be
turned off. Two hooks use your own gh credentials: a once-per-session
star prompt that only reads your star status
(CLAUDE_NIGHT_MARKET_NO_STAR_PROMPT=1 disables it), and a session-stop
hook that posts a learnings discussion and may open issues
(auto_post_learnings: false in
~/.claude/skills/discussions/config.json disables it). The third,
delegation through conjure, sends prompts and file contents to an
external model CLI under the credentials you configured for it
(CONJURE_DELEGATION=off for one run). What each sends, and every
switch, is in Network and Data.

Plugin Development

make validate-all
make lint && make test   # checks only; rewrites nothing
make fix                 # ruff format + ruff check --fix

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. Working on this repo needs Python 3.12+
and GNU make 3.82+. The guide covers both, including why
Xcode's make 3.81 reports a green build it did not run.

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.
