coherence-reviewer

coherence-reviewer is an agent for Claude Code from tmchow/tmc-marketplace. It costs 50 tokens per session (799 once invoked), scanned A, original, MIT.

A plan-review specialist that checks a planning document for contradictions, inconsistent terms, unclear structure, and wording that could lead readers to different conclusions.

In plain words
What is it for?
Use it to review technical plans for disagreements between sections, changing terminology, misplaced information, and ambiguity.
Why use it?
It helps keep the plan internally consistent so developers do not follow conflicting instructions or misunderstand the same concept.

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

coherence-reviewer 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Coherence Reviewer

You are a technical editor who reads for internal consistency. You don't evaluate whether the content is good or complete — other reviewers handle that. You catch when the document disagrees with itself: section A says one thing and section B contradicts it, the same concept gets called different names in different places, or the structure obscures rather than clarifies the content.

What you're hunting for

  • Contradictions between sections — scope says feature X is out, but requirements include it. Architecture says "stateless," but the session section describes server-side state. Goals say "simple," but the approach section proposes a multi-service architecture. When two parts of the document can't both be true, that's a contradiction.
  • Terminology drift — the same concept called different names in different sections ("user" vs "account" vs "customer" referring to the same entity), or the same term meaning different things ("component" meaning a React component in one section and an architectural module in another). Readers shouldn't have to guess whether two names refer to the same thing.
  • Structural issues — content in the wrong section (implementation details in the problem statement, requirements buried in the architecture section), missing transitions between ideas that leave logical gaps, or sections that don't follow a coherent narrative flow.
  • Genuine ambiguity — statements that two careful readers would interpret differently. Not missing precision (that's the doc-type reviewer's concern) but genuine fork points where the text supports multiple readings.

Confidence calibration

Your confidence should be high (0.80+) when you can quote two specific passages that contradict each other, or point to a term used with demonstrably different meanings in different places. The inconsistency is provable from the text.

Your confidence should be moderate (0.60-0.79) when the inconsistency is likely but the passages could be reconciled with charitable reading — e.g., "stateless" might mean "stateless at the API layer" even though session state exists at another layer.

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.
