agent-skills AGENTS.md

agent-skills AGENTS.md is an instructions file for Codex, OpenCode from PracticalSwan/agent-skills. It costs 4,068 tokens per session, scanned A, original, MIT.

A set of instructions for AI agents working in a shared skills repository. It defines required startup reading, validation, syncing, and publishing steps.

In plain words
What is it for?
Use it to guide sessions that update the repository, including reading required context, running validation, syncing changes, and publishing satisfactory work.
Why use it?
It gives agents a consistent process for making and completing repository changes. An agent is an AI tool that can inspect or modify files on a user's behalf.

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 A, and why

agent-skills AGENTS.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 today.

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.

The opening of the file, as written. The whole thing — 367 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

This repository contains shared skills for GitHub Copilot, Claude Code, and Codex, and this file defines the workspace-specific rules that should apply to any AI agent operating in C:\Users\LOQ\.copilot\skills.

Required Session Start Rule

  • Every new session in this workspace must begin by reading LESSON.md.
  • Treat LESSON.md as required startup context before analysis, planning, edits, validation, reviews, or advisory work.
  • If LESSON.md is missing or unreadable, stop and report that blocker before continuing.

Required Completion, Sync, And Publish Rule

  • For every user-requested mutation task in this workspace, complete the requested work in C:\Users\LOQ\.copilot\skills first.
  • After the work is complete, run the repo validation, then sync outward to the downstream skill folders every time.
  • If the AI agent judges the result satisfactory, commit and push to GitHub without asking for another confirmation.
  • Treat work as satisfactory only when validation passes, sync completes, the task is complete, no requested step was skipped, no required command was rejected, no unresolved secret/security/privacy issue remains, and the final diff matches the user's request.
  • Elevate to the user before commit or push when there are security concerns, incomplete work, skipped steps, rejected or blocked required commands, validation/sync failures, unexpected unrelated dirty files that make staging unsafe, or any other reason the work is not satisfactory.
  • For read-only or advisory tasks with no file changes, do not create empty sync, commit, or push churn; report that no mutation workflow was needed.

Workspace Role

  • Main branch: C:\Users\LOQ\.copilot\skills
  • New maintained skills must be added or imported here first.
  • Maintained skills live here and are synced outward to downstream targets.
  • Copied official superpowers are tracked here for discovery and cross-client sync, but they are not maintained the same way as the catalog's maintained skills.

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.
