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 | $0.00154 | $0.03702 |
| Opus 5.5 | $0.00062 | $0.01481 |
| Sonnet 5.5 | $0.00031 | $0.00740 |
| Haiku 4.5 | $0.00015 | $0.00370 |
Grade A, and why
bv-mcp-check-conventions 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 yesterday.
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.

bv-mcp-check-conventions is a skill published in the GitHub repository MadaBurns/bv-mcp (9 stars, last pushed yesterday), with no licence file. It adds 154 tokens to every session and 3,702 once invoked, about $0.0006 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 2026-09-11.
Other skills, from other repositories
code-search
Search a codebase efficiently with ripgrep regular expressions, file globs, and git history search. Use to locate symbols, usages, and definitions instead of reading whole files.
systematic-debugging
Applies a modified Fagan Inspection methodology to resolve persistent bugs and complex issues. Use when several fix or debugging attempts have already failed and a methodical root-cause analysis warranting a Fagan inspection is needed. Do not use for simple troubleshooting.
reframe-voice
Write, rewrite, or review content in the evidence-led reframe voice style. Use when the user explicitly asks to write in "reframe voice" or "reframe style". Do NOT use for general writing tasks.
chimera-carry-the-failure-forward
A retry loop that overwrites its feedback variable shows attempt 3 only the failure of attempt 2 — so it re-derives the patch attempt 1 already tried.
chimera-ground-it-in-the-source
Take the signature from the installed version, not from memory — a plausible API is indistinguishable from a real one until it runs.
chimera-reproduce-before-diagnosing
A diagnosis is a claim about a machine you have not run. Reproduce the failure in one short command first — especially when the diagnosis arrived from someone else.
