What is agent-plugins copilot-instructions.md?

A repository instruction file for an agent-skills catalogue that collects skills from many provider repositories and publishes generated JSON catalogues.

Use it when maintaining provider definitions, parsing skill files, generating catalogue outputs, or checking the automated daily aggregation.

It explains how the catalogue is aggregated, versioned, and consumed, so changes fit the existing update workflow.

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	$0.03904	$0.03904
Opus 5.5	$0.01562	$0.01562
Sonnet 5.5	$0.00781	$0.00781
Haiku 4.5	$0.00390	$0.00390

Security

Grade A, and why

agent-plugins copilot-instructions.md 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 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.

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.

Agent Skills Directory - AI Agent Instructions

Project Overview

This repository aggregates agent skills from the provider repositories configured in PROVIDERS (Anthropic, OpenAI, GitHub, Vercel, HuggingFace, Stripe, Cloudflare, Supabase, and many community repos) into a unified JSON catalog consumed by MCP servers and AI agents. A GitHub Action runs daily at 06:00 UTC to fetch the latest skills, generating versioned releases with YYYY.MM.DD format.

Current stats: read total_skills and providers in catalog.json (or the README badges); do not hardcode counts in docs.

Key consumers: MCP Mother Skills server.

Architecture

Core Components

scripts/aggregate.py - Main aggregation script
- Fetches skills from GitHub API using tree endpoints
- Parses SKILL.md files with YAML frontmatter
- Generates 2 output formats: catalog.json, catalog.min.json
- Regenerates the README plugin table between the AUTO-GENERATED SKILLS TABLE markers
- Uses GITHUB_TOKEN env var to avoid rate limits
Provider System - Extensible provider configuration (lines 35-207 in aggregate.py)
```
PROVIDERS = {
    "provider-id": {
        "name": "Display Name",
        "repo": "https://github.com/org/repo",
        "api_tree_url": "https://api.github.com/repos/.../git/trees/main?recursive=1",
        "raw_base": "https://raw.githubusercontent.com/.../main",
        "skills_path_prefix": "skills/",  # Can be "" for root-level SKILL.md
    }
}
```
- Add new providers by extending this dict - no other code changes needed
- Supports root-level SKILL.md files (single-skill repos) with skills_path_prefix: ""
- Some repos use master branch instead of main - adjust URLs accordingly
- Provider stats include stars and description fetched from GitHub API
Category System - Keyword-based auto-categorization (lines 67-74)
- Maps skills to categories: documents, development, creative, enterprise, integrations, data, security, cloud, mobile, ml-ai, testing, devops, web, other
- Based on keyword matching in name/description
- To add categories: extend CATEGORY_KEYWORDS dict

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.
