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.

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 | $0.00082 | $0.00852 |
| Opus 5 | $0.00041 | $0.00426 |
| Sonnet 5 | $0.00016 | $0.00170 |
| Haiku 4.5 | $0.00008 | $0.00085 |
Grade A, and why
mine-plugins scanned grade A with 0 findings 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 yesterday.
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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Dependencies
This skill requires Python 3.8+ and standard library only. No external packages needed.
To install this skill's dependencies:
pip-compile ./requirements.in
pip install -r ./requirements.txt
See ./requirements.txt for the dependency lockfile (currently empty — standard library only).
Mine Plugins
Run the full analysis pipeline on a plugin or collection of plugins. This is the one-shot command for the virtuous cycle.
What This Command Does
- Inventory — Enumerate and classify every file in the target
- Analyze — Deep structural and content analysis using the
analyze-pluginskill - Extract — Identify all design patterns (known and novel)
- Synthesize — Generate improvement recommendations using the
synthesize-learningsskill - Report — Produce a comprehensive analysis report
Usage
/mine-plugins <path-to-plugin-or-directory>
Examples
# Analyze a single plugin
/mine-plugins claude-knowledgework-plugins/sales
# Analyze an entire collection
/mine-plugins claude-knowledgework-plugins/
# Analyze our own plugins
/mine-plugins plugins/legacy\ system
Execution Steps
Step 1: Determine Scope
Check if $ARGUMENTS points to:
- A single plugin (contains
.claude-plugin/plugin.jsonorskills/directory) → Single Plugin Mode - A directory of plugins (contains multiple subdirectories with plugins) → Comparative Mode
- A single skill (contains
SKILL.md) → Single Skill Mode
Step 2: Run Inventory
For each plugin in scope, run:
python "scripts/inventory_plugin.py" --path "$ARGUMENTS" --format json
Security scanning is enabled by default. The inventory script runs credential detection, network call detection, and environment variable access checks on every script file. Pass
--no-securityonly if you want to suppress the security scan output.
If the script fails, perform manual inventory per the analyze-plugin skill Phase 1.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- yesterday First seen · 116 lines · 82 tokens per session scan A dba0a99f85a0
mine-plugins is a skill published in the GitHub repository richfrem/agent-plugins-skills (6 stars, last pushed yesterday), licensed MIT. It adds 82 tokens to every session and 852 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
