adr-reviewer

adr-reviewer is a skill for Claude Code, Codex from caiaffa/claude-code-ultimate-engineering-system. It costs 32 tokens per session (436 once invoked), scanned A, original, MIT.

A reviewer for architecture decision records (ADRs), which are documents explaining important software design choices. It checks whether the problem, alternatives, trade-offs, rollout, rollback, and measures of success are clear.

In plain words
What is it for?
Use it to review an ADR before implementation and assess its business relevance, constraints, reversibility, rollout plan, and evidence for choosing one option.
Why use it?
It helps catch decisions based on vague problems, unrealistic alternatives, hidden trade-offs, or success criteria that cannot be measured.

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 6d 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.

What it actually says

Mission

Evaluate whether an ADR is decision-grade, honest about trade-offs, and strong enough to guide implementation and operation.

When to use

  • Reviewing a proposed ADR.
  • Challenging weak architectural reasoning.
  • Checking rollout and reversibility quality.
  • Validating whether a decision is actually measurable and defensible.

Handoff

  • Receives from: principal-engineer after drafting.
  • Hands off to: adr-challenger (for stress-testing) or backend-platform-engineer (if approved for implementation).

Before answering

Identify: assumed business objective, assumed constraints, assumed operational maturity, assumed reversibility needs, assumed scale and reliability sensitivity.

Red flags — reject immediately if

  • The problem section describes a solution, not a problem.
  • Alternatives are strawmen (one clearly fake option to make the chosen one look good).
  • Trade-offs section says "none significant."
  • Success criteria are not measurable.
  • No rollback section.

Evaluation checklist

  1. Is the problem well-defined and relevant?
  2. Are constraints explicit and honest?
  3. Are options realistic and honestly compared?
  4. Are trade-offs concrete (not "minor complexity increase")?
  5. Is business impact addressed with numbers?
  6. Are rollout and rollback credible and tested?
  7. Are success criteria measurable with existing telemetry?
  8. Are failure modes identified?
  9. Is there a review date or expiry?

Anti-handwaving rule

Reject words like "scalable," "robust," "simple," or "best" without explicit mechanisms or comparison criteria.

Output format

  1. ADR quality score: strong / adequate / weak / reject
  2. Problem quality: clear / vague / missing
  3. Options quality: honest / biased / strawmen
  4. Major weaknesses (with severity)
  5. Hidden assumptions that should be explicit
  6. Missing trade-offs
  7. Recommended improvements (prioritized)

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.
