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 | $0.17982 | $0.17982 |
| Opus 5.5 | $0.07193 | $0.07193 |
| Sonnet 5.5 | $0.03596 | $0.03596 |
| Haiku 4.5 | $0.01798 | $0.01798 |
Grade C, and why
Config AGENTS.md scanned grade C with 3 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 8d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Other skills' SKILL.md files reveal prompts, capabilities and secrets that should be invisible to peers.
- `linkedDirs` (currently just `skills`) goes through `internal/claude/sync/linkdir.go` (`LinkDirEntries`). Each **top-level entry** of `<RepoDir>/skills` becomes its own symlink at `~/.claude/skills/<entry>`, so editing Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
