Revise

Revise

You are tasked with updating existing implementation plans based on user feedback. You should be skeptical, thorough, and ensure changes are grounded in actual codebase reality.

Input

$ARGUMENTS accepts two shapes:

1. Workflow form — --plans <plan-path> --reviews <review-path>. The orchestrator wires both upstream artifacts in. The plan path is the file to update; the review path carries the findings that drive the edits. Treat the review's content as the feedback.
2. Manual form — <plan-path> "<feedback>", e.g. .rpiv/artifacts/plans/2025-10-16_09-00-00_feature.md "Split Phase 2 into two phases".

Recognize the workflow form by the --plans / --reviews flag tokens; recognize the manual form by the absence of those flags. When both --plans and --reviews are present, read the review FULLY and synthesize its findings as the feedback set.

Metadata

node "${SKILL_DIR}/../_shared/now.mjs"
echo
echo "### recent (read only in case of empty user input)"
echo "recent plans:"
node "${SKILL_DIR}/../_shared/list-recent.mjs" .rpiv/artifacts/plans 10

Flow

1. Input → 2. Research if needed → 3. Present approach → 4. Update plan → 5. Sync & review → 6. Follow-ups

The revised artifact stays in .rpiv/artifacts/plans/ for /skill:implement to resume.

Steps

Step 1: Input Handling

When this command is invoked:

1. Parse the input to identify:

   • Workflow flags: --plans <path> (the plan to update) and --reviews <path> (review carrying the findings to apply). Both flags may repeat for multi-artifact upstreams.
   • Manual form: positional plan path + free-text feedback.
   • Whether the user accidentally provided a review artifact path as the positional plan in the manual form.

2. Handle different input scenarios:

   If --plans AND --reviews flags are present (workflow form):

   • Take the --plans value as the plan file path.
   • Read the --reviews artifact FULLY (the review findings are the feedback set).
   • Skip directly to substep 3 — no preliminary questions needed.

   If a REVIEW artifact path is provided:

   `revise` updates implementation plans, not review artifacts.
   
   If you want to act on code-review findings, provide the target plan path plus the changes to make.
   
   Example:
   `/skill:revise .rpiv/artifacts/plans/2025-10-16_09-00-00_feature.md "Address the findings from .rpiv/artifacts/reviews/2025-10-16_10-00-00_feature.md by tightening validation in Phase 2 and expanding success criteria."`
   

   Wait for user input.

   If NO plan file provided, branch on the recent plans: listing in the Metadata block:

   • Empty — no plans under .rpiv/artifacts/plans/; tell the user and suggest running /skill:plan first.
   • Exactly one entry — confirm with ask_user_question: "Revise this plan?" with options "Revise <filename> (Recommended)" and "Pick a different path".
   • Two or more entries — present the top 4 filenames as ask_user_question options.

   If the user is coming from /skill:code-review, also ask which findings should change the plan. Wait for user selection, then re-check for feedback.

   If plan file provided but NO feedback:

   I've found the plan at {path}. What changes would you like to make?
   
   For example:
   - "Add a phase for migration handling"
   - "Update the success criteria to include performance tests"
   - "Adjust the scope to exclude feature X"
   - "Split Phase 2 into two separate phases"
   

   Wait for user input.

   If BOTH plan file AND feedback provided:

   • Proceed to substep 3 — no preliminary questions needed.

3. Read the existing plan file COMPLETELY:

   • Use the Read tool WITHOUT limit/offset parameters
   • Understand the current structure, phases, and scope
   • Note the success criteria and implementation approach

4. Understand the requested changes:

   • Parse what the user wants to add/modify/remove
   • Identify if changes require codebase research
   • Determine scope of the update

Step 2: Research If Needed

Only spawn research tasks if the changes require new technical understanding.

If the user's feedback requires understanding new code patterns or validating assumptions:

1. Spawn parallel agents for research using the Agent tool: For code investigation:

   • Use the codebase-locator agent to find relevant files
   • Use the codebase-analyzer agent to understand implementation details
   • Use the codebase-pattern-finder agent to find similar patterns

   For historical context:

   • Use the artifacts-locator agent to find related research or decisions in .rpiv/artifacts/
   • Use the artifacts-analyzer agent to extract insights from documents

   Be EXTREMELY specific about directories:

   • Include full path context in prompts

2. Read any new files identified by research:

   • Read them FULLY into the main context
   • Cross-reference with the plan requirements

3. Wait for ALL agents to complete before proceeding

Step 3: Present Understanding and Approach

Before making changes, confirm your understanding:

Based on your feedback, I understand you want to:
- {Change 1 with specific detail}
- {Change 2 with specific detail}

My research found:
- {Relevant code pattern or constraint}
- {Important discovery that affects the change}

I plan to update the plan by:
1. {Specific modification to make}
2. {Another modification}

Does this align with your intent?

Header is capped at ≤16 characters (MAX_HEADER_LENGTH = 16 — longer values are rejected). Use the ask_user_question tool to confirm before editing. Question: "{Summary of planned modifications}. Proceed with these edits?". Header: "Changes". Options: "Proceed (Recommended)" (Apply the planned changes to the existing plan); "Adjust approach" (Modify what will be changed before editing); "Show me first" (Show the exact text changes before applying).

Step 4: Update the Plan

1. Make focused, precise edits to the existing plan:

   • Use the Edit tool for surgical changes
   • NEVER use Write tool - plan files already exist, use Edit tool only
   • Maintain the existing structure unless explicitly changing it
   • Keep all file:line references accurate
   • Update success criteria if needed

2. Ensure consistency:

   • If adding a new phase, ensure it follows the existing pattern
   • If modifying scope, update "What We're NOT Doing" section
   • If changing approach, update "Implementation Approach" section
   • Maintain the distinction between automated vs manual success criteria
   • Uncheck modified work. When editing the body of a phase that already carries - [x] checkmarks, change - [x] back to - [ ] for every item whose acceptance is no longer guaranteed by the prior implementation (changed steps, changed success criteria, new sub-steps). Leave checkmarks intact only on items whose existing implementation still satisfies the revised criteria. This is load-bearing: /skill:implement trusts checkmarks when resuming a plan, so a stale - [x] on a rewritten phase silently skips the new work whenever the next-step Phase {N} arg is dropped.
   • If the plan has YAML frontmatter, set last_updated to <iso> from the Metadata block; set last_updated_by to your name. Copy the offset verbatim — do not reformat.
   • Rebuild phases: if present. If the frontmatter carries a phases: array, rebuild it from the ## Phase N: headings after your edits — one { n, title } entry per heading, in body order.

3. Preserve quality standards:

   • Include specific file paths and line numbers for new content
   • Write measurable success criteria
   • Use project's build/test commands (make, npm, etc.) for automated verification
   • Keep language clear and actionable

Step 5: Sync and Review

1. Present the changes made:

   Plan updated at `.rpiv/artifacts/plans/{filename}.md`
   
   Changes made:
   - {Specific change 1}
   - {Specific change 2}
   
   The updated plan now:
   - {Key improvement}
   - {Another improvement}
   
   Let me know if you want further adjustments — otherwise chain forward.
   
   ---
   
   💬 Follow-up: describe further plan changes in chat — each `/skill:revise` call appends another timestamped Follow-up section, history is preserved.
   
   **Next step:** `/skill:implement .rpiv/artifacts/plans/{filename}.md Phase {N}` — resume execution at the affected phase (or omit `Phase {N}` to run all phases sequentially).
   
   > 🆕 Tip: start a fresh session with `/new` first — chained skills work best with a clean context window.
   

Step 6: Handle Follow-ups

• Each invocation appends history. Every /skill:revise call adds another timestamped Follow-up section — do not collapse history. Prior phase decisions stay visible.
• Bump frontmatter. Update last_updated + last_updated_by; set last_updated_note: "<one-line summary of revision>".
• Surgical edits only. Make precise edits to specific phases or success criteria — not wholesale rewrites. Preserve good content that doesn't need changing.
• When to re-invoke instead. For deep architectural changes, the upstream design or research is the right place to revise — re-run those rather than expanding revise's scope. The previous block's Next step: stays valid for the existing plan.

Important Guidelines

1. Be Skeptical:

   • Don't blindly accept change requests that seem problematic
   • Question vague feedback - ask for clarification
   • Use AskUserQuestion tool for structured clarification when there are multiple valid approaches
   • Verify technical feasibility with code research
   • Point out potential conflicts with existing plan phases

2. Be Surgical:

   • Make precise edits, not wholesale rewrites
   • Preserve good content that doesn't need changing
   • Only research what's necessary for the specific changes
   • Don't over-engineer the updates

3. Be Thorough:

   • Read the entire existing plan before making changes
   • Research code patterns if changes require new technical understanding
   • Ensure updated sections maintain quality standards
   • Verify success criteria are still measurable

4. Be Interactive:

   • Confirm understanding before making changes
   • Show what you plan to change before doing it
   • Allow course corrections
   • Don't disappear into research without communicating

5. Track Progress:

   • Update todos as you complete research
   • Mark tasks complete when done

6. No Open Questions:

   • If the requested change raises questions, ASK
   • Research or get clarification immediately
   • Do NOT update the plan with unresolved questions
   • Every change must be complete and actionable

Success Criteria Guidelines

When updating success criteria, always maintain the two-category structure:

1. Automated Verification (can be run by execution agents):

   • Commands that can be run: make test, npm run lint, etc.
   • Specific files that should exist
   • Code compilation/type checking

2. Manual Verification (requires human testing):

   • UI/UX functionality
   • Performance under real conditions
   • Edge cases that are hard to automate
   • User acceptance criteria

Subagent Invocation Best Practices

When spawning research agents:

1. Only spawn if truly needed - don't research for simple changes
2. Parallel dispatch — every Agent(...) call in the same assistant message (multiple tool_use blocks in one response), never one per turn. Call shape: Agent({ subagent_type: "<agent-name>", description: "<3-5 word task label>", prompt: "<task>" }).
3. Each agent should be focused on a specific area
4. Provide detailed instructions including:
   • Exactly what to search for
   • Which directories to focus on
   • What information to extract
   • Expected output format
5. Request specific file:line references in responses
6. Wait for all agents to complete before synthesizing
7. Verify agent results - if something seems off, spawn follow-up agents
