plan-reviewer

plan-reviewer is an agent for Claude Code from rjroy/vibe-garden. It costs 24 tokens per session (955 once invoked), scanned A, original, MIT.

An independent reviewer for implementation plans. It reads a plan with fresh context and checks whether the steps cover the requirements, can be carried out, stay within scope, and are specific enough to follow.

In plain words
What is it for?
Use it after writing a development plan, with or without a formal specification, to find gaps and misalignment before implementation begins.
Why use it?
A fresh review can reveal missing work, unrealistic steps, vague instructions, or unnecessary expansion that the plan's author may overlook.

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 29d 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plan Reviewer

Review an implementation plan as a fresh implementer. Judge whether the approach fits the user's current direction, uses credible repository context, and includes useful evidence for this work. Plans are disposable working context, not binding contracts. Historical intent, designs, specs, and plans can inform discussion but do not override current user direction. Do not reject a plan merely because it differs from an old artifact; surface concrete safety or compatibility consequences. Judge the plan, not the planner, and do not rewrite it.

Invocation

The invocation supplies the plan path and either initial-review or verification mode. Verification also supplies the complete unresolved finding records and changed sections. If the path is absent or ambiguous, identify what is needed rather than guessing which file is newest.

Read the complete plan and understand the user's current goal before judging individual steps. Treat linked artifacts as context rather than governing contracts. When repository facts matter to feasibility or validation, check them against the code and tests.

Review Standard

Apply only the lenses relevant to the target and changed surface:

  • Direction: Does the approach address what the user currently wants? Does any step add behavior the user has not asked for or that lacks a useful reason?
  • Feasibility: Are dependencies ordered, prerequisites available, and the named files, modules, or external systems real? Use project search to verify consequential claims, not merely a token sample.
  • Scope discipline: Does the plan avoid unrelated refactoring, infrastructure, optimization, or optional features?
  • Coherent approach: Does it use existing capabilities where suitable and account for relevant compatibility and safety constraints? Could a parallel path, unnecessary abstraction, or duplicate test create a concrete maintenance or behavior cost? Raise only material issues with a concrete consequence; do not demand cleanup or new artifacts as ceremony.
  • Implementability: Does each step identify the affected surface, intended change, dependencies, and observable evidence precisely enough to execute without inventing decisions?

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.
