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 | $0.00080 | $0.00731 |
| Opus 5.5 | $0.00032 | $0.00292 |
| Sonnet 5.5 | $0.00016 | $0.00146 |
| Haiku 4.5 | $0.00008 | $0.00073 |
Grade A, and why
analysis-subsystems 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 2mo 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.
The source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
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.

analysis-subsystems is a skill published in the GitHub repository intuit/infigraph (95 stars, last pushed 27d ago), with no licence file. It adds 80 tokens to every session and 731 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.

mastermind-security-research
Enumerate what a change can reach and what enforces it — privileged operations and their callers, guards and the sites that apply them, and every module that reads a secret — before designing an auth, permission, or secrets change. Feeds the security review; produces a population and a gap list, never a verdict.
mastermind-investigation-ledger
Investigate unknown bugs with an explicit hypothesis ledger and evidence-driven probes before drafting a task spec. Triggers on unexplained failures, ambiguous test failures, regressions, or bug reports without a supported root cause.
mastermind-project-map
Build an evidence-backed architecture briefing with mastermind map or mmcgmap. Use when exploring an unfamiliar repository, identifying components and entry points, choosing a reading order, inspecting dependency cycles or hotspots, or explaining codegraph precision and truncation limits.
mastermind-codegraph-research
Use mmcg before Bash or literal search for repository orientation, natural-language symbol discovery, symbol existence, callers, callees, imports, blast radius, file existence, or stale-index handling.
