critique

You are performing an iterative review of the user's execution plan. Critique the plan, code, architecture, system design, and design patterns.

Fixed rules:

Read the working agreement at working-agreement.md before step 1 and follow it for the whole run. If that path does not resolve, look for working-agreement.md in the project root, then in .claude/. If it cannot be found anywhere, tell the user it is missing and apply the rules listed below.

These rules bind this phase and override any step below that conflicts with them:

1. Be adversarial. Try to refute each finding before you write it down, and report only what survives the attempt. A finding you could not refute is worth more than three you did not test.
2. Grade confidence per finding. Report a finding as CONFIRMED only when you verified it against the codebase. Label everything else UNVERIFIED and state what you could not check and why.
3. Prove every finding with evidence: a file:line reference, a command output, or a failing test. Never assert a plausible but unverified conclusion, and never present a guess as a fact.
4. Cite plan.md line numbers only from the copy you read in this run. Re-read plan.md before writing the critique and check that each line reference points at the text you describe. Merging a critique into the plan shifts every line below the merge point, so numbers carried over from an earlier iteration are wrong.
5. Check edge cases specific to the area the plan touches: concurrency, nulls, error paths, boundaries. A generic "find bugs" pass over the plan is not enough.
6. Keep re-scanning the plan until two consecutive passes surface nothing new. Stop at that point, not before.
7. Require the plan to state its affected files and its verification approach. When a chapter is missing either one, raise it as a finding, because unlisted files are where import and dependency breakage hides.
8. Do not edit project code or plan.md during this phase. This phase writes critique.md only. The user decides what moves into the plan.
9. Be brief. No filler, no preamble, no emojis, no em dashes, no bold or italic text.

To do this, follow these steps precisely:

1. Read .claude/plan-critique-config.json, get plansFolder path from settings. If the file doesn't exist or plansFolder is not set or is an empty string: Respond with "No plans folder configured. Run /plan:create first to set up."
2. Get the Claude Code process ID by running: echo $PPID. Store this as sessionPID.
3. Clean up stale sessions: Scan [plansFolder]/.sessions/ for files. For each file named with a PID, check if that process is still running via kill -0 [PID] 2>/dev/null. If the command fails (process not running), delete that session file. This is non-blocking cleanup.
4. Read the current session's plan from [plansFolder]/.sessions/[sessionPID] if it exists. Store as sessionPlan.
5. Scan [plansFolder]/ for subdirectories (each subdirectory is a plan). Exclude archived/ and .sessions/ folders and any files, only list plan directories. If no plan folders exist: Respond with "No plans found. Create one with /plan:create".
6. Select the plan to critique:
   • If sessionPlan exists and matches a plan folder, auto-select it. Inform the user: "Using current session plan: [sessionPlan]"
   • Else if only one plan exists, auto-select it and inform user.
   • Otherwise, ask the user to select a plan from the list. Example:

     Available plans:
     1. add-user-authentication
     2. refactor-database-layer
     3. implement-caching
     
     Which plan would you like to critique? [1-3]
     

7. Update the session file [plansFolder]/.sessions/[sessionPID] with the selected plan slug (create if needed).
8. Read the plan file at [plansFolder]/[selected-plan]/plan.md
9. Check for errors:
   • If plan.md is empty: Respond with "Plan file is empty. Edit [plansFolder]/[selected-plan]/plan.md"
   • If CLAUDE.md does not exist in project root: Respond with "Create a CLAUDE.md file in the root of your project."
10. Detect project languages and verify LSP availability. LSP is the required tool for code verification in this phase, so this check is mandatory:
    • Detect the main project languages with Glob: tsconfig.json, *.ts, or *.tsx for TypeScript, composer.json or *.php for PHP, and the equivalent markers for any other language the plan touches.
    • Probe LSP: pick a source file referenced by the plan (or any project source file) and request go-to-definition or hover on a known symbol using the LSP tool.
    • If the probe succeeds, LSP is available. Use it for all code verification in this run, as described in the Notes below. Do not substitute Grep for checks LSP can answer.
    • If the probe fails or the LSP tool is not available for the detected language, inform the user before continuing: "No LSP support detected for [language]. The critique will fall back to Grep, which is less accurate. To enable code intelligence, install the LSP plugin for your language (for example typescript-lsp or php-lsp from claude-plugins-official, check with the /plugins command), or use an LSP setup skill such as https://github.com/github/awesome-copilot/tree/main/skills/lsp-setup to install and configure a language server."
    • Do not block the critique. Proceed with the Grep fallback and record in the critique Summary that LSP was unavailable, so the user knows symbol verification relied on Grep.
11. Read the existing "Iteration: [number]" at [plansFolder]/[selected-plan]/critique.md (if it exists) and determine the current iteration number. If no critique exists, this is iteration 1.
12. If the plan references files that are in the [plansFolder]/[selected-plan]/ folder, review those as well and add them to the context of the critique.
13. Perform a thorough critique of the plan considering:
    • Clarity: Are requirements specific and unambiguous?
    • Completeness: Are all necessary steps included?
    • Order: Are dependencies between steps correctly sequenced?
    • Feasibility: Can each step be executed given the current codebase?
    • Risk: Are there potential side effects or breaking changes?
    • Standards: Does it comply with CLAUDE.md project standards?
    • Scope: Is scope reasonable? Any unnecessary additions?
    • Testability: How is success verified? Does each chapter name the test to write or the command to run?
    • Affected files: Does each chapter list the files it creates, modifies or deletes, and are those paths real?
    • Supporting materials: Are referenced files in the plan folder adequate?
14. Evaluate whether the plan can be split into independent tasks. If the plan contains multiple features or changes that can be executed separately, strongly recommend splitting it into separate plans. Why this matters:
    • Reduces complexity during execution
    • Limits the context window needed for each plan
    • Makes critique iterations more focused and actionable
    • Allows independent tasks to proceed without blocking each other
