coverage-binding

coverage-binding is a skill for Claude Code, Codex from jstoup111/ai-conductor. It costs 15 tokens per session (941 once invoked), scanned A, original, Apache-2.0.

A narrow checker that decides whether a stated completion condition is explicitly required by the cited checks. It does not inspect the code or infer that related work is enough.

In plain words
What is it for?
Use it to review acceptance criteria, especially when checking whether tests or other Done-when checks actually cover a requested behaviour.
Why use it?
It prevents a task from being marked complete merely because the implementation seems related to the requirement. It distinguishes direct evidence from assumptions.

Token cost

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.

Security

Grade A, and why

coverage-binding 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 24d 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 opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Judgement policy

Each claim is judged independently against its cited task's Done when checks. For each claim, answer this one question: does at least one cited check assert that claim's criterion? No claim's verdict may be inferred from another claim.

Return asserts only when a cited check explicitly requires the criterion's behavior. Topical adjacency, related implementation work, or a plausible inference is does-not-assert when the check does not actually require that behavior.

Judge observable outcomes, not wording. A check that requires the same observable outcome with equal or greater precision asserts it, even when phrased differently: "rejected naming the field" asserts "the rejection names the field", and "byte-identical" asserts "equal". A check with lesser precision does not: "deep-equal" does not assert "byte-identical". A criterion clause that only restates the consequence of an asserted check's failure under an existing gate (for example "fails before the change can land" when the check asserts the integrity suite fails) is asserted by that check. Every other outcome in the criterion, including absence and no-op outcomes, still needs a check that requires it.

A check asserts every outcome its required observable state entails. A check that pins an exact final state asserts the absence of any other change to that state: "the inbox listing equals the seeded listing minus the claimed file" asserts "no other inbox file is renamed", and "ledger.json is byte-identical before and after" asserts "no entry's status, attempts, or timestamps change". Judge entailment from the supplied text alone; do not assume implementation behavior.

Judge only the supplied criterion's own clauses. Never require an outcome the criterion does not state, and never require a check to restate a criterion word whose observable outcome the check already pins. Before returning does-not-assert, name in missingAssertion the exact criterion clause no cited check requires, quoted from the criterion; if you cannot quote one, the verdict is asserts.

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.

coverage-binding is a skill published in the GitHub repository jstoup111/ai-conductor (7 stars, last pushed yesterday), licensed Apache-2.0. It adds 15 tokens to every session and 941 once invoked, about $0.0001 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 2026-09-06.
