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 | $0.00452 | $0.00452 |
| Opus 5 | $0.00226 | $0.00226 |
| Sonnet 5 | $0.00090 | $0.00090 |
| Haiku 4.5 | $0.00045 | $0.00045 |
Grade A, and why
gopilot CLAUDE.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 6d 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.
What it actually says
Development Guidelines
Project Structure
This is a Claude Code skill plugin (not a Go application). Content lives in markdown files:
skills/gopilot/SKILL.md— main skill contentskills/gopilot/reference/*.md— detailed reference docs (security, AIP, etc.)skills/go-tdd-baby-steps/SKILL.md— TDD skill
Workflow
Adding or updating skill content
- Edit the relevant markdown files in
skills/ - If adding a new reference doc, link it from
SKILL.md - Update the coverage table in
README.mdto reflect new topics - Run
make checkto validate skill format - Run
make bumpto increment the patch version - Commit and push
Validation
make check # Runs npx skill-check . to validate skill format
Always run make check before pushing. CI runs the same check on PRs to main.
Versioning
make bump # Increments patch version in plugin.json and marketplace.json
Always run make bump after content changes — never edit version fields by hand. The script asserts all three locations match before bumping, so a manual edit will cause the next bump to fail with a drift error.
Version is tracked in:
.claude-plugin/plugin.json(.version).claude-plugin/marketplace.json(.metadata.versionand.plugins[0].version)
Commit conventions
Follow existing style: imperative mood, short summary line.
Add go-aip guidelines for resource-oriented gRPC APIs
Fix ordering field.Path type in go-aip reference
Bump version to 1.0.17
Skill content guidelines
- Keep patterns concise and actionable — this is a reference, not a tutorial
- Include code examples where they clarify usage
- Reference Go version for version-specific features (e.g., "Go 1.24+")
- Prefer stdlib over external dependencies
- When referencing aip-go or other libraries, verify function signatures exist in the actual package
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.

gopilot CLAUDE.md is an instructions file published in the GitHub repository gonzaloserrano/gopilot (17 stars, last pushed 2mo ago), licensed MIT. It adds 452 tokens to every session, about $0.0023 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 2026-08-30.
