What is ancplua-claude-plugins CLAUDE.md?

Contributor instructions for a Claude Code plugin marketplace, which is a repository that distributes add-ons through a catalogue file. It explains the repository layout, plugin files, and required path and version conventions.

Use it when adding or changing Claude Code plugins, their commands, agents, skills, hooks, or connected tool servers.

It helps changes pass the repository's checks and ensures newly added or updated plugins are actually recognized by the marketplace.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01140	$0.01140
Opus 5	$0.00570	$0.00570
Sonnet 5	$0.00228	$0.00228
Haiku 4.5	$0.00114	$0.00114

Security

Grade C, and why

ancplua-claude-plugins CLAUDE.md scanned grade C 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 9d 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

How it starts

The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ancplua-claude-plugins

A Claude Code plugin marketplace — a git repo that distributes plugins (commands, agents, skills, hooks, MCP servers) through a marketplace.json manifest. Claude Code only — no other CLI mirrors, no non-Claude models. The plugin inventory and install steps live in README.md; this file is the contributor / dev guide.

Repo structure

.claude-plugin/marketplace.json   # Claude Code marketplace manifest (lists every plugin)
plugins/<name>/                   # one directory per plugin (17 today)
.github/workflows/ci.yml          # JSON + manifest validation — the only gate
automation/                       # cron cleanup runner — IGNORE for dev (see automation/policy.md)
README.md                         # user-facing: what each plugin does + how to install

Plugin layout

Each plugin under plugins/<name>/:

.claude-plugin/plugin.json   # required: name, version, description
commands/  agents/  skills/  hooks/   # all optional
README.md                    # per-plugin docs

Manifest path rule: component/source paths in plugin.json and marketplace.json must start with ./ (agent paths also end in .md). A bare path fails recent CLIs with <field>: Invalid input.

Adding or changing a plugin

Create/edit plugins/<name>/ with a valid .claude-plugin/plugin.json.
Register it in .claude-plugin/marketplace.json. Each entry needs name, source (./plugins/<name>), description.
Bump the plugin's version on any behavioral change (see next section).
Validate, commit, open a PR.

Version bumps reach the cache; edits don't

Installed plugins run from ~/.claude/plugins/cache/<marketplace>/<plugin>/<version>/, pinned to the installed commit — not from this working tree. /plugin update re-syncs the cache only when the version string changes; on an equal version it reports "already at the latest" and keeps running the old code. A fix committed without a version bump never reaches the running plugin.

Changes

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.
