Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add instructions/trtmn/agent-plugins/claude-mdgit clone --depth 1 https://github.com/trtmn/agent-pluginsWhat 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 | $0.00965 | $0.00965 |
| Opus 5 | $0.00483 | $0.00483 |
| Sonnet 5 | $0.00193 | $0.00193 |
| Haiku 4.5 | $0.00097 | $0.00097 |
Grade B, and why
agent-plugins 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 2d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
- `.gitignore` — excludes `**/.claude/settings.local.json`, `**/evals/`, workspace dirs, `.DS_Store` How it starts
The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Overview
A Claude Code plugin marketplace. Plugins live under plugins/; .claude-plugin/marketplace.json at the repo root registers them all.
Install path:
/plugin marketplace add trtmn/agent-plugins
/plugin install <plugin-name>@agent-plugins
Plugin Directory Structure and Conventions
See AGENTS.md — it is the canonical source for the required plugin directory layout, plugin.json/SKILL.md/CHANGELOG.md conventions, the $CLAUDE_PLUGIN_ROOT path convention (and its exceptions), and when a plugin needs a setup command. Read it before creating or modifying any plugin.
PII Prevention — applies to every commit, not just plugin work
This repo mirrors to a public GitHub repo. Before committing anything — plugin code, docs/, root-level files — see AGENTS.md's "PII Prevention" section and run its mandatory pre-commit sweep. It has already happened once (a personal Tailscale hostname, SSH username, and machine names leaked via docs/ and a plugin, requiring a git filter-repo history rewrite across every branch). docs/ is not exempt — everything in this repo gets committed and pushed the same way.
Existing Plugins
cowsay, font-extractor, home-assistant, homebrew-dev, imsg, jellyfin, mastodon-cli, obsidian-cli, preflight-check, pushover, quack, recipe-fetch, self-improvement, side-quest, skills-manager, tailscale-policy-manager, touch_file, unifi-api, video-extract, wp-custom-theme, wp-local, youtube-data-api, yt-dlp.
self-improvement is the full learning loop in one plugin (as of v2.0.0 it absorbed the former standalone learnings plugin). It ships two skills + three agents:
- Capture (
learningsskill + agent) — autonomous. Main Claude delegates to thelearningssubagent in the background on every correction/error/suggestion; it appendsStatus: pendingentries to~/.learnings/. - Review + auto-promote (
self-improvementskill + agent, plus thelearning-investigatoragent) — autonomous and manual. A gatedSessionEndhook spawns a detached headlessclaude -preview;/self-improvementruns the same pipeline foreground. Thelearning-investigatorjudges each entry against a conservative bar and the orchestrator auto-promotes qualifiers (user-scope) intoCLAUDE.md, logging a revertible trail to~/.learnings/CHANGELOG.md. Undo with/self-improvement:revert <PROMO-hex>. Wire it up with/self-improvement:setup.
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.

agent-plugins CLAUDE.md is an instructions file published in the GitHub repository trtmn/agent-plugins (2 stars, last pushed 5d ago), licensed Unlicense. It adds 965 tokens to every session, about $0.0048 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
