adr-reviewer

adr-reviewer is a skill for Claude Code, Codex from harumiWeb/exstruct. It costs 66 tokens per session (614 once invoked), scanned A, original, BSD-3-Clause.

A review process for checking whether an Architecture Decision Record (ADR) makes a sound design decision and is supported by the project’s code, tests, and specifications.

In plain words
What is it for?
It helps review an ADR after automated lint checks, compare it with related decisions and specifications, verify its claims, and identify design or safety risks.
Why use it?
It catches duplicated or conflicting decisions, weak evidence, missing rollout or compatibility details, and choices that require human ownership before the ADR is merged.

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

adr-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 5d 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.

ADR Reviewer

Review the policy decision, not just the document shape.

Read

  1. dev-docs/agents/adr-governance.md
  2. dev-docs/agents/adr-criteria.md
  3. dev-docs/agents/adr-workflow.md
  4. dev-docs/specs/adr-review.md
  5. The target ADR draft
  6. Related ADRs, relevant public docs under docs/ when public API / CLI / MCP contracts are in scope, internal specs, tests, src paths, and issue / PR context
  7. Existing adr-linter findings for the current draft

Workflow

  1. Confirm the current draft has no unresolved adr-linter high / medium findings. Only proceed with design review after that precondition is met.
  2. Read the ADR draft and identify the single policy question it is trying to resolve.
  3. Check whether the draft overlaps with, contradicts, or should supersede an existing ADR or spec.
  4. Verify that the cited Tests, Code, and Related specs actually support the claims being made, and include relevant public docs/ pages in scope when the ADR touches public API / CLI / MCP contracts.
  5. Review whether compatibility, rollout, fallback, migration, or safety consequences are covered when relevant.
  6. Detect human-owned decisions that AI should not settle, including public API break judgment, security or license calls, major directory reorganization, or unresolved product/spec direction.
  7. Return one verdict:
    • ready
    • revise
    • escalate

Output Contract

Return findings first, ordered by severity, and include:

  • verdict
  • scope
    • draft
    • related ADRs
    • public docs
    • specs
    • src
    • tests
    • issue / PR context
  • findings

Each finding should include:

  • type
    • decision-gap
    • scope-conflict
    • evidence-risk
    • rollout-gap
    • ownership-escalation
  • severity
  • summary
  • why it matters
  • suggested revision
  • evidence
    • draft
    • related sources

Also include top-level:

  • open questions
  • residual risks

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.
