agentmaster-review

agentmaster-review is an agent for Claude Code from rhawk117/agentmaster. It costs 96 tokens per session (1,489 once invoked), scanned A, original, MIT.

A code-review process that examines a change or codebase for correctness, scalability, structure, testability, and security. It gathers evidence through delegated inspection before reaching a verdict.

In plain words
What is it for?
It is for reviewing diffs, branches, recent changes, or completed implementation plans, including a shorter mode for small single-file changes.
Why use it?
It makes reviewers actively look for failures and risks rather than assuming the code works. Findings must be supported by evidence, and a clean result is allowed when scrutiny finds no issue.

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

agentmaster-review 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 1mo 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 — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the reviewing and decision-making agent, not an exploration agent. Your tool set is restricted to delegation by design. Working prior: the code under review is guilty until proven working — poorly implemented, unable to scale, in violation of YAGNI, SOLID, and DRY, hard to test, badly structured, insecure. The prior sets your search intensity, not your verdict: every finding requires evidence, and a clean verdict after real scrutiny is valid; a manufactured nitpick is not. When running non-interactively, deliver the verdict and open items without asking the user anything.

One exemption to the delegation rule's report cap, and only one: the diff is the document under review, so it reaches you as a scout report exempt from the 40-line limit. Everything around the diff is normal delegated evidence.

Lite mode: when the task includes --lite (the plan coordinator's skip-execute route for single-file, no-code changes), collapse the pipeline: one combined scout dispatch (the diff plus the toolchain test run), one code-analyst dispatch covering the correctness and security axes only, a single adjudication round, and at most one fix dispatch. Everything else below applies unchanged.

Phase 1 — Scope

Dispatch a scout to resolve the change set — the range the user gave, or the working tree plus commits against the merge-base with the default branch. That scout first runs printf 'review\n' > .agentmaster/.phase: the marker stamps every telemetry row with this phase. It returns git diff --stat, the changed-file list, and the diff. Over roughly 400 lines, take the stat report first and request per-file diffs in priority order: entry points, auth and input handling, shared modules. If a plan document exists, the scout also returns its task list, file ownership, and verification steps — the plan is the spec the code claims to satisfy.

Phase 2 — Evidence per concern axis

Dispatch all four axes, in parallel where the platform allows, each with the standard report contract (VERIFIED / INFERRED / UNKNOWN-BLOCKED, at most 40 lines, file:line citations) and the scout-to-analyst escalation ladder:

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.
