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 | $0.00000 | $0.00655 |
| Opus 5.5 | $0.00000 | $0.00262 |
| Sonnet 5.5 | $0.00000 | $0.00131 |
| Haiku 4.5 | $0.00000 | $0.00065 |
Grade A, and why
check scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.
check - verify behavior or explain how to try it
Context reuse: Reuse any required file already loaded in project instructions or the current session. Read it again only if absent, changed, or exact current bytes or line references are needed.
Select the mode before any tool call
/check guideor$check guide: generate a read-only manual walkthrough. Pass remaining arguments such aslatest, a step, a path, route, or command toreference/guide.md. Read and follow that reference only. Do not write activity state, run checks or the app, edit files, update spec status, or produce verification receipts.- A natural-language request for instructions on how the user can manually test or review a change also selects guide mode. If the request mixes a guide with agent verification, clarify which mode to run first before any activity.
/checkor$check, optionally with a verification scope: verify observed behavior against the spec. Follow verification startup below, then read and followreference/verify.mdonly.
Load only the selected reference. Do not read both references preemptively.
Guide generation never satisfies a verification gate. The existing
qualityGates.regular.tryGuide and qualityGates.continuous.tryGuide keys now
select /check guide. manual, always, and when-user-facing retain their
existing behavior. when-testable asks guide mode to classify whether the work
has a safe, meaningful observation path and generate a compact ## Try it now
section only when one exists. The separate check gates continue to select
verification mode.
Verification startup (verification mode only)
First action: Before project inspection, preflight, or any other tool call,
publish running to blueprint/.state/run.json when blueprint/.state/
exists, with command check. From the project root, run the first helper that
exists, node .agents/skills/blueprint-doctor/scripts/run-state.mjs or
node .claude/skills/blueprint-doctor/scripts/run-state.mjs, with start --command <skill> --summary "<truthful summary>" --boundary <read-only|reviewed|local-only>. Use update at milestones, with --status blocked --resume <command> for a blocker, and finish --status ready|completed
at the end; --help lists every option and blueprint/workflow.md has the full
activity contract. A missing or failing helper is a warning, not a blocker. This
precedes reading the verification reference. Guide mode must skip this startup
entirely.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

check is a skill published in the GitHub repository aiblueprinthq/ai-blueprint (493 stars, last pushed 7d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 655 tokens. 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.
