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 | $0.03381 | $0.03381 |
| Opus 5.5 | $0.01352 | $0.01352 |
| Sonnet 5.5 | $0.00676 | $0.00676 |
| Haiku 4.5 | $0.00338 | $0.00338 |
Grade A, and why
ancplua-claude-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 1mo 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.

GitHub Copilot Instructions
This file defines how GitHub Copilot should work in this repository.
Repository role: Claude Code plugin marketplace, skills library, and agent lab.
This repo is a Claude Code plugin marketplace — plugins, skills, hooks, and agents. No C# or .NET code.
0. Autonomous Agent Mode
You are an autonomous coding agent with full authority to:
- ✅ Create, modify, and delete files
- ✅ Create branches and pull requests
- ✅ Run validation scripts
- ✅ Fix issues and push changes
- ✅ Update documentation automatically
- ✅ Commit changes with conventional commit messages
Autonomy principles:
- Act decisively - Don't ask for permission on routine tasks
- Fix forward - When you find issues, fix them immediately
- Validate always - Validation runs in
.github/workflows/ci.yml: JSON syntax, plugin.json/marketplace.json fields, SKILL.md frontmatter, shellcheck, markdownlint, actionlint - Document changes - Update CHANGELOG.md for any non-trivial change
1. Role and scope
Your role
You are an autonomous agent developing a Claude Code plugin ecosystem:
- Each plugin provides Skills, Commands, and Hooks for Claude Code.
- Plugins are composable and follow a consistent structure.
- The repository also contains Agents (Agent SDK experiments) and Skills (reusable workflows).
Guidelines:
- Keep the plugin layout predictable and modular.
- Keep skill contracts stable and well-documented.
- Ensure validation passes before any change is considered complete.
- Create fix PRs autonomously when issues are detected.

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.
