In plain words

Use it when adding, updating, validating, or documenting plugins, skills, agents, and hooks in the alexmskills project.
Why use it?
It helps coding agents understand how the marketplace is organized and how its plugins should be maintained consistently.

Instructions file for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: reads .claude/ paths; mentions .claude-plugin; mentions CLAUDE.md.

This is alexmond/alexmskills's own configuration. It tells Claude Code how to work on alexmskills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything alexmskills configures →

Runs only inside a plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else, and the catalogue could not identify which plugin ships it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

alexmskills CLAUDE.md scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 16d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

How it starts

The opening of the file, as written. The whole thing — 170 lines — stays where its author put it; the contents beside it link to each section on GitHub.

alexmskills

A public Claude Code plugin marketplace of reusable, self-improving skills and agents. Each skill is an independently versioned plugin. This file is the project's working memory; the README is the public front door.

Layout

.claude-plugin/marketplace.json   # the catalog — every plugin + its source/version
plugins/<name>/                   # one directory per plugin
  .claude-plugin/plugin.json      #   manifest (name, version, author, …)
  skills/<skill>/SKILL.md         #   one or more skills
  agents/<agent>.md               #   subagents (review-agents, dev-crew)
  hooks/hooks.json                #   plugin-shipped hooks (evolving-claude-md)

scripts/validate-marketplace.sh   # jq-based validator (also run in CI)
Makefile                          # validate / list / bump helpers
.claude/                          # per-plugin state (mindmap, prompt-coach, skill-linter)

Catalog (see README for descriptions)

evolving-claude-md, memory-hygiene, dev-crew, brainstorm-panel, learn-on-failure, roles, prompt-coach (self-learning) · implement-issue, maven-quality, security-audit, screenshot-tour, progress-channel, ticket-triage, context-bar, usage-bar (workflow) · review-agents (review) · research-sweep (research) · skill-linter (self-learning). Beta (-beta suffix): tune-repo-beta, systemic-fix-beta.

Conventions

  • One skill = one plugin, unless skills are tightly coupled (then bundle + version them together, like maven-quality). This is what makes per-skill versioning possible at all.
  • Every plugin.json carries the same metadata shape: name, description, version (semver), author (Alex Mondshain / [email protected]), homepage, repository, license: MIT, keywords. The name MUST match its marketplace.json entry.
  • Bump versions with make bump PLUGIN=<n> VERSION=<x.y.z> so plugin.json and marketplace.json never drift. Validate with claude plugin tag --dry-run plugins/<n>.
  • Run make validate before committing. CI runs it too.
  • Skills must be project-agnostic. No hardcoded absolute paths, usernames, or repo names — these are pulled FROM other repos and generalized; keep them that way.
  • Docs are part of "done": a new plugin needs a docs/modules/ROOT/pages/<n>.adoc page, a nav.adoc entry and a row on index.adoc; every version bump gets a CHANGELOG.md entry (grouped by date, tagged with plugin + version). make validate enforces all three — it was a convention until the landing page drifted four plugins behind the catalog.
  • Plugin naming: orchestrators are <scope>-<team-noun>, the team-noun encoding coordination (crew = handoff/deliver, panel = debate/decide, sweep = fan-out/discover); other skills are descriptive kebab-case, verb-first for actions, ≤3 words, no redundant qualifiers.
  • Role naming: a role is named for the persona (a noun — who they are), never the task (a verb — what they do), so it reads right seated solo, in a crew, on a panel, or in a sweep. Coverage roles use <dimension>-scout. Role names are shared across orchestrators (one skeptic, one architect).
  • Never push or cut release tags without explicit user confirmation.
  • Attribution: all plugins are original work by the author (MIT, per plugin.json author); the roles-plugin personas credit @nahidulislam404's prompt thread as inspiration. This is a public-repo provenance note; don't drop it in a cleanup.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
