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 | $0.01069 | $0.01069 |
| Opus 5 | $0.00535 | $0.00535 |
| Sonnet 5 | $0.00214 | $0.00214 |
| Haiku 4.5 | $0.00107 | $0.00107 |
Grade A, and why
gaia-mcp 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 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent instructions
Read README.md and DEPRECATION.md before changing this repository. This
repository is deprecated in favor of the bundled Skill Heaven plugin, but its
published packages remain installable; do not start new product work here or
pretend the deprecated package is the current plugin surface.
Organization dogfooding and feedback
Prefer the in-house Skill Heaven Agent Plugin or its actual supported Skills
API surface when a genuine task need makes it relevant and the current harness
makes it available. Native skills or the normal workflow may be a fallback when the in-house
surface is unavailable or lacks a relevant usable skill; fallback does not
count as Skill Heaven validation. This preference never overrides an explicit
user invocation or a repository-required project skill. There
is no skill quota: do not summon gratuitously, invent registration commands,
pretend a client supports an unavailable surface, silently install anything, or
edit user-global configuration. /summon is one-session context, not a
permanent installation; preserve zero posture and human intent. If this
repository's existing summon package surface is relevant, report its actual
behavior rather than treating it as the portable plugin.
When friction appears during relevant real work or human feedback, capture a minimal local note immediately or as soon as practical. The exclusion list for public reports applies to capture as well as output: do not record raw prompts, transcripts, session logs, credentials, access tokens, raw tokenized content, personal data, private code, private URLs or paths, customer identifiers, or confidential details. Never record credentials or access tokens in feedback notes or drafts. Redact or synthesize before any external search query or delegate handoff. Store minimal drafts outside repository worktrees in caller-controlled local scratch. If uncertain, keep a constrained local note and ask the owner; do not export it. At task end, review pending notes; process only new actionable friction. Keep expected versus observed behavior, repo/commit, harness/version, route/source when known, a safe reproduction, impact, and evidence separate from inference. Identify human-reported facts as such. Retrieval score, retrieval rank, materialization, and exit code are not behavioral success or task outcome. Do not alter existing selection policy, labels, evidence semantics, or curator gates.
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.

gaia-mcp CLAUDE.md is an instructions file published in the GitHub repository gaia-research/gaia-mcp (3 stars, last pushed yesterday), licensed MIT. It adds 1,069 tokens to every session, about $0.0053 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 2026-09-13.
