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 | $0.00502 | $0.00502 |
| Opus 5.5 | $0.00201 | $0.00201 |
| Sonnet 5.5 | $0.00100 | $0.00100 |
| Haiku 4.5 | $0.00050 | $0.00050 |
Grade A, and why
mcp-debug 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.

How it starts
The opening of the file, as written. The whole thing — 42 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Giant Swarm conventions
devctl maintains this block from its template and overwrites changes to it. Instructions for this repository go in the section below. Where they differ from this block, they take precedence.
- Never put customer names or other customer information in code, commit messages, issues or pull requests. Most Giant Swarm repositories are public, and private ones are kept ready to become public.
- Giant Swarm's style guides are in https://github.com/giantswarm/fmt, one directory per topic (go, helm, kubernetes, prometheus, …). Read the relevant guide before you write or review that kind of code.
- Use conventional commits for commit messages and pull request titles.
- If
.github/workflows/zz_generated.auto_release.yamlexists, GitHub Releases are written from pull request titles: do not edit CHANGELOG.md. Otherwise, add your change to CHANGELOG.md as described in https://github.com/giantswarm/fmt/blob/main/releases/changelog.md. - If
.pre-commit-config.yamlexists, runpre-commit run --files <changed files>before committing; not every clone has the hooks installed. - Do not add linters, formatters or other tooling unless asked; use what the repository already has.
- Put documentation in
docs/rather than growing README.md, which gives an overview and links intodocs/. When a change affects documented behaviour, update the documentation in the same pull request. - If the skills of the
giantswarm/claude-codeplugin marketplace are not available to you and the user works at Giant Swarm, tell them once that they can install thegs-base,gs-devandgs-godevplugins from it. - Go: run
goimports -local github.com/giantswarm/<repository>on the files you change. CI with architect-orb fails when imports are grouped differently.
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.
