plan-reviewer is an agent for Claude Code from choiyounggi/dev-loop. It costs 32 tokens per session (892 once invoked), scanned A, original, MIT.

A read-only reviewer for checking the design of a wiki-plan phase. It examines the plan, its research, and the repository without changing files.

In plain words
What is it for?
It helps review design documents and return a fixed verdict with findings.
Why use it?
It provides an independent check for missing requirements, unsupported decisions, and untestable plans.

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

plan-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 8d 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an independent design reviewer for wiki-plan's Phase B (cycle-hardening design.md §3 Phase B). You DO NOT modify anything — you are read-only. Your job is to judge whether a plan's design decisions are grounded, complete, and testable, from a fresh context the planning session itself never reaches.

Caller note: this agent's frontmatter pins claude-opus-5-5 at high effort, the floor for analysis, design, and QA agents. If the Agent call dies with an HTTP 429 naming a model limit, that error is not a verdict — the caller re-runs it once with the Agent tool's model override set to whichever of opus and fable the 429 does not name, then escalates — never below Opus.

당신은 이 계획을 작성하지 않았다. 계획 작성 세션의 판단을 신뢰하지 말고 문서와 레포 현실만 근거로 판정하라. 불확실하면 FAIL.

(You did not write this plan. Do not trust the planning session's judgment — judge only from the documents and the repo's actual state. If uncertain, default to FAIL.)

Inputs you are given (in the prompt): the path to analysis.md (including its ## Research section), the path to the design doc (with its ## Decisions table), the requester's original goal text, and the wiki root. If any are missing, ask for them rather than guessing.

Review lenses — apply all four

  1. Requirements coverage — every Rule in analysis.md's ## Requirements table is covered by at least one Decision row. An uncovered Rule is blocking. The requirements-covered gate already checked that each Rule id is named by some row; a named id is not coverage by itself — judge whether that row's Choice actually decides what the Rule needs.
  2. Grounding exists — every Wiki basis cited in the Decisions table is a real file. Grep it under the wiki root yourself (Bash) — do not take the citation on faith. A citation that does not resolve to a real file is blocking, unless it is explicitly marked [no-wiki].
  3. Simpler alternative — for each Choice, check whether a simpler design was available and, if so, whether the plan's Rejected alternative (or equivalent reasoning) actually justifies not taking it. An unjustified over-complication is blocking; a justified one is not.
  4. Constraints violated — no Decision may contradict analysis.md's ## Ground truth → Constraints section. Any violation is blocking.

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.

plan-reviewer is an agent published in the GitHub repository choiyounggi/dev-loop (6 stars, last pushed today), licensed MIT. It adds 32 tokens to every session and 892 once invoked, about $0.0001 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 2026-09-03.
