Plan ENG Review

When to Use

• After a plan has been written and before coding starts
• When the user wants a tech-lead-style architecture audit
• When the plan may be missing failure modes, edge cases, or rollback strategy

When NOT to Use

• No plan file exists — use writing-plans first
• You want strategic review — use plan-ceo-review
• The code exists and you need diff review — use requesting-code-review

Workflow

Step 1: Resolve the plan path

• If [plan-path] argument provided, use it
• Else scan: docs/claudekit/plans/*.md, docs/plans/*.md (generic fallback), plan.md in cwd
• Newest by mtime wins
• None found → stop and tell user to run /claudekit:writing-plans first

Step 2: Dispatch the eng-reviewer agent

Invoke the Agent tool with subagent_type: "eng-reviewer". Pass:

• The absolute plan path
• The 5 dimensions (data flow, failure modes, edge cases & invariants, test matrix, rollback & migration)
• The required output format

Step 3: Present the scorecard

Show the returned ENG Review markdown verbatim.

Step 4: Single consolidation gate

AskUserQuestion with the Recommended fixes checklist. Skip if empty.

Step 5: Apply selected fixes

For each selected fix, use Edit on the plan file. Each fix is either:

• Replace "<old>" with "<new>" → Edit with old_string=<old>, new_string=<new>
• In section "<heading>", add: <text> → Read the file, locate the heading, use Edit to append <text> under it

If a fix is too vague to apply deterministically (fails the concreteness contract), skip it and report to the user as Unapplied: <reason>.

Step 6: Write the review artifact

Save to docs/claudekit/reviews/<plan-basename>-eng-YYYY-MM-DD.md with Applied fixes and Skipped fixes sections.

Identical structure to plan-ceo-review but with ENG rubric.
