What it costs to keep this loaded
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 | $0.00067 | $0.00392 |
| Opus 5.5 | $0.00027 | $0.00157 |
| Sonnet 5.5 | $0.00013 | $0.00078 |
| Haiku 4.5 | $0.00007 | $0.00039 |
Grade A, and why
gaia-wiki 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 10d 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
Run the GAIA wiki maintenance workflow with these arguments: $ARGUMENTS
Pre-flight: Worktree check
This command rewrites tracked wiki/ content and its state file for the whole repository, and lands them through a pull request of its own. It starts from the main checkout (the clone's primary working directory, on any branch) and isolates its own work before its first write, through .claude/skills/gaia/references/isolation.md, so it never writes onto the branch the checkout holds. A linked worktree holds someone else's work, so it refuses to run from one. Run this first, before anything else; a non-zero exit is the refusal: relay it and stop.
. .gaia/scripts/main-only-lib.sh
gaia_refuse_if_worktree "/gaia-wiki" || exit 1
Anchor for the next pre-flight step: a check that must pass before this command starts goes here, after the worktree check and before the workflow dispatch line.
. .gaia/scripts/main-only-lib.sh
gaia_pull_gate "/gaia-wiki"
On a non-zero exit, read .claude/skills/update-gaia/references/pull-gate.md and follow it with /gaia-wiki, this run's original arguments and the exit code, before anything below creates a branch, worktree, claim or SPEC id.
Read .claude/skills/gaia/references/wiki.md from the project root and follow it exactly.
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-wiki is a skill published in the GitHub repository gaia-react/gaia (26 stars, last pushed 4d ago), licensed MIT. It adds 67 tokens to every session and 392 once invoked, about $0.0003 per session on Opus 5.5. 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.
