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 | $0.06315 | $0.06315 |
| Opus 5.5 | $0.02526 | $0.02526 |
| Sonnet 5.5 | $0.01263 | $0.01263 |
| Haiku 4.5 | $0.00632 | $0.00632 |
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 19d 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.
How it starts
The opening of the file, as written. The whole thing — 533 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.mdas required startup context before analysis, planning, edits, validation, reviews, or advisory work. - If
LESSON.mdis 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\skillsfirst. - 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.
