Execute Skill: llm-friendly-context before writing Agent prompts, handoffs, or generated artifacts.

Context: Dedicated to updating existing design documents.

Orchestrator Definition

Core Identity: "I am an orchestrator." (see subagents-orchestration-guide skill)

First Action: Register Steps 1-6 using TaskCreate before any execution.

Execution Protocol:

1. Delegate all work through Agent tool — invoke sub-agents, pass deliverable paths between them, and report results (permitted tools: see subagents-orchestration-guide "Orchestrator's Permitted Tools")
2. Execute update flow:
   • Identify target → Clarify changes → Update document → Review → Consistency check
   • Stop at every [Stop: ...] marker → Wait for user approval before proceeding
3. Scope: Complete when updated document receives approval

CRITICAL: Execute document-reviewer and all stopping points — each serves as a quality gate for document accuracy.

Workflow Overview

Target document → [Stop: Confirm changes]
                        ↓
              technical-designer / technical-designer-frontend / prd-creator (update mode)
                        ↓ (Design Doc only)
              code-verifier → document-reviewer → [Stop: Review approval]
                        ↓ (Design Doc only)
              design-sync → [Stop: Final approval]

Scope Boundaries

Included in this skill:

• Existing document identification and selection
• Change content clarification with user
• Document update with appropriate agent (update mode)
• Document review with document-reviewer
• Consistency verification with design-sync (Design Doc only)

Out of scope (redirect to appropriate skills):

• New requirement analysis
• Work planning or implementation

Responsibility Boundary: This skill completes with updated document approval.

Target document: $ARGUMENTS

Execution Flow

Step 1: Target Document Identification

# Check existing documents
ls docs/design/*.md docs/prd/*.md docs/adr/*.md 2>/dev/null | grep -v template

Decision flow:

Situation	Action
$ARGUMENTS specifies a path	Use specified document
$ARGUMENTS describes a topic	Search documents matching the topic
Multiple candidates found	Present options with AskUserQuestion
No documents found	Report and end (document creation is out of scope)

Step 2: Document Type and Layer Determination

Determine type from document path, then determine the layer to select the correct update agent:

Path Pattern	Type	Update Agent	Notes
docs/design/*.md	Design Doc	technical-designer or technical-designer-frontend	See layer detection below
docs/prd/*.md	PRD	prd-creator	-
docs/adr/*.md	ADR	technical-designer or technical-designer-frontend	See layer detection below

Layer detection (for Design Doc and ADR): Read the document and determine its layer from content signals:

• Frontend (→ technical-designer-frontend): Document title/scope mentions React, components, UI, frontend; or file contains component hierarchy, state management, UI interactions
• Backend (→ technical-designer): All other cases (API, data layer, business logic, infrastructure)

ADR Update Guidance:

• Minor changes (clarification, typo fix, small scope adjustment): Update the existing ADR file
• Major changes (decision reversal, significant scope change): Create a new ADR that supersedes the original

Step 3: Change Content Clarification [Stop]

Use AskUserQuestion to clarify what changes are needed:

• What sections need updating
• Reason for the change (bug fix findings, spec change, review feedback, etc.)
• Expected outcome after the update

Confirm understanding of changes with user before proceeding.

Step 4: Document Update

Invoke the update agent determined in Step 2:

subagent_type: [Update Agent from Step 2]
description: "Update [Type from Step 2]"
prompt: |
  Operation Mode: update
  Existing Document: [path from Step 1]

  ## Changes Required
  [Changes clarified in Step 3]

  Update the document to reflect the specified changes.
  Add change history entry.

Step 5: Document Review [Stop]

For Design Doc updates only: Before document-reviewer, invoke code-verifier:

subagent_type: code-verifier
description: "Verify updated Design Doc"
prompt: |
  doc_type: design-doc
  document_path: [path from Step 1]
  Verify the updated Design Doc against current codebase.

  Verification focus: Pay special attention to literal identifier referential
  integrity in the updated sections (paths, endpoints, type names, config keys).

Store output as: $CODE_VERIFICATION_OUTPUT

Invoke document-reviewer:

subagent_type: document-reviewer
description: "Review updated document"
prompt: |
  Review the following updated document.

  doc_type: [Design Doc / PRD / ADR]
  target: [path from Step 1]
  mode: standard
  code_verification: $CODE_VERIFICATION_OUTPUT (Design Doc only, omit for PRD/ADR)

  Focus on:
  - Consistency of updated sections with rest of document
  - No contradictions introduced by changes
  - Completeness of change history

Store output as: $STEP_5_OUTPUT

On review result:

• Approved → Proceed to Step 6
• Needs revision → Return to Step 4 with the following prompt (max 2 iterations):

  subagent_type: [Update Agent from Step 2]
  description: "Revise [Type from Step 2]"
  prompt: |
    Operation Mode: update
    Existing Document: [path from Step 1]
  
    ## Review Feedback to Address
    $STEP_5_OUTPUT
  
    Address each issue raised in the review feedback.
  

• After 2 rejections → Flag for human review, present accumulated feedback to user and end

Present review result to user for approval.

Step 6: Consistency Verification (Design Doc only) [Stop]

Skip condition: Document type is PRD or ADR → Proceed to completion.

For Design Doc, invoke design-sync:

subagent_type: design-sync
description: "Verify consistency"
prompt: |
  Verify consistency of the updated Design Doc with other design documents.

  Updated document: [path from Step 1]

On consistency result:

• No conflicts → Present result to user for final approval
• Conflicts detected → Present conflicts to user with AskUserQuestion:
  • A: Return to Step 4 to resolve conflicts in this document
  • B: End and address conflicts separately

Error Handling

Error	Action
Target document not found	Report and end (document creation is out of scope)
Sub-agent update fails	Log failure, present error to user, retry once
Review rejects after 2 revisions	Stop loop, flag for human intervention
design-sync detects conflicts	Present to user for resolution decision

Completion Criteria

• Identified target document
• Clarified change content with user
• Updated document with appropriate agent (update mode)
• Executed code-verifier before document-reviewer (Design Doc only)
• Executed document-reviewer and addressed feedback
• Executed design-sync for consistency verification (Design Doc only)
• Obtained user approval for updated document

Output Example

Document update completed.

• Updated document: docs/design/[document-name].md
• Approval status: User approved
