coherence-check

coherence-check is a skill for Claude Code, Codex from jstoup111/ai-conductor. It costs 50 tokens per session (6,352 once invoked), scanned A, original, Apache-2.0.

A traceability document tool used during the DECIDE stage for medium or large specifications. It maps requested outcomes, requirements, architecture decisions, stories, and tasks to one another and records whether each connection is covered.

In plain words
What is it for?
Use it to create an auditable coverage map for a planned feature when the coherence gate applies.
Why use it?
It exposes missing or contradictory links in a plan before implementation begins. The judgments are based on the actual project documents, not just matching labels.

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

coherence-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 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.

How it starts

The opening of the file, as written. The whole thing — 407 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Authors .docs/coherence/<plan-stem>.md: a single committed artifact mapping every intake outcome bullet, every PRD FR (product track), every non-deleted ADR file in the current spec change set when the coherence gate engages, every story, and every plan task to its counterpart ids with a per-row verdict. This artifact is the auditable traceability record the operator (and the land-time coherence validator) reads instead of trusting self-reported "everything's covered" prose in a spec PR.

Any current-change-set .docs/decisions/adr-* path, including a deletion, engages the ADR layer. That engagement is distinct from the ADR row pool: deleted ADRs produce no row, so a deletion-only change has no ADR row to author.

Correctness gate: a row's verdict (covered / gap / fail) is a judgment call, not a mechanical grep. Coverage, consistency, and achievability are separate questions: a counterpart can exist and still contradict what it implements (§4d), or be compatible with a criterion without delivering it (§4g). Per the /verify-claims protocol, ground every verdict in the actual cited text — do not mark a row covered on the assumption that a plausible-looking counterpart id exists; confirm it against the real artifact file.

1. Tier Rule (M/L only)

Read the spec's tier from .docs/complexity/.

  • Tier S: this skill does NOT run. Skip it entirely — same treatment as architecture-diagram/architecture-review/conflict-check for S tier. No .docs/coherence/ artifact is authored, and the land-time validator does not engage for S-tier specs (Story 13). Do not author a stub file "to be safe" — its mere presence is not required and produces work the S-tier exemption exists to avoid.
  • Tier M: this skill runs, using the session's default model (no override).
  • Tier L: this skill runs, pinned to opus for the dispatch (see Section 2).

2. Model Rule (M = session default, L = pinned opus)

This skill is tier-varying, the same pattern as conflict-check and plan:

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.

coherence-check is a skill published in the GitHub repository jstoup111/ai-conductor (7 stars, last pushed today), licensed Apache-2.0. It adds 50 tokens to every session and 6,352 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
