Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00157 | $0.04488 |
| Opus 5.5 | $0.00063 | $0.01795 |
| Sonnet 5.5 | $0.00031 | $0.00898 |
| Haiku 4.5 | $0.00016 | $0.00449 |
Grade A, and why
elenchus-build 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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
What ships with it
3 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.

Other skills, from other repositories
code-health
Scans the codebase for dead code, tech debt, outdated dependencies, and code quality issues. Delegates to the Centinela (QA) agent.
review-findings
Addresses and fixes findings from a QA code review. Reads the review report, fixes critical and warning issues, and prepares for re-verification. Delegates to the Forja (Dev) agent.
consult-codex
Dual-AI code analysis pairing OpenAI Codex with Claude code-searcher — the lightest consult variant, two citation-verified perspectives. Use for a quick second opinion on a code question.
mstar-audit
Audit or survey a codebase into an evidence-backed, prioritized review report (read-only): bugs, security, perf, test gaps, tech debt, DX, a PR/branch/diff (pr variant), test-suite audit.
mstar-review-qc
QC orchestration: SDD mandatory plan QC tri-review (qc1…qc3 + consolidated), inline/hotfix single seat, tri identity gate, residual registration. Read before dispatching or consolidating QC.
mstar-pr-loop
Opt-in skill loaded when the user explicitly asks for a review → fix loop on an existing ready PR, or when iteration Phase 1 selects it as that iteration's prmergepolicy: reviewed-auto review path. It never activates for routine review requests or on its own initiative.
