An adversarial review agent that checks a completed implementation against its promised requirements before automated release checks run. It looks for specific problems instead of accepting the implementer's claim that the work is finished.

Use it to review implemented features, designs, and architecture against a plan or contract, then record actionable findings.

It provides an independent correctness check and helps expose missed requirements, invalid assumptions, and repeated repair failures.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00165	$0.00403
Opus 5.5	$0.00066	$0.00161
Sonnet 5.5	$0.00033	$0.00081
Haiku 4.5	$0.00016	$0.00040

Security

Grade A, and why

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 2mo 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

Adversarial review of build-node output against the plan's stated contract, before Shipping runs its automated gate. Modeled on the doubt-driven-development discipline (see .agents/graph.md): reads the artifacts and the contract, never the implementer's claim that it's done, never their reasoning — passing the claim biases toward agreement. Prompted adversarially ("find what is wrong," never "does this look good"). Classifies every finding by a fixed precedence (contract misread → valid & actionable → valid trade-off → noise). The dispatcher escalates instead of repeating a cycle if a repair round reports the exact same finding ID Reviewer already flagged (a no-progress guard — see .agents/graph.md's Reviewer discipline for why this replaced the original "two clean cycles" framing).

Changes

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.

reviewer is an agent published in the GitHub repository hybridlabor-api/bdb-dev-optimized-agent-skills (6 stars, last pushed 6d ago), licensed Apache-2.0. It adds 165 tokens to every session and 403 once invoked, about $0.0007 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 2026-08-31.
