Execute Skill: llm-friendly-context before writing Agent prompts, handoffs, or generated artifacts. Execute Skill: subagents-orchestration-guide before making workflow decisions, invoking agents, or resolving findings.

Context: Dedicated to updating existing design documents.

Orchestrator Definition

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

Local authority gate: Make this recipe's workflow decisions and validate each returned result directly; delegate semantic deliverable production to the named specialist.

Review Resolution Gate [MANDATORY]: Resolve every actionable deliverable-review finding through subagents-orchestration-guide Review Resolution before correction or progression. Before the first finding disposition, read references/review-resolution.md from the loaded subagents-orchestration-guide skill.

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

Execution Protocol:

1. Invoke named specialists for deliverable production — pass deliverable paths between them and validate their results (see subagents-orchestration-guide "Orchestrator Execution Boundary")
2. Execute update flow:
   • Identify target → Clarify changes → Update document → Review → Consistency check
   • Stop at the [Stop: Final approval] marker → Wait for user approval before completing
3. Scope: Complete when updated document receives approval

At each Agent invocation below, build the prompt as a mechanical extraction: copy the named source values into the exact fields, apply only the declared serialization, then invoke immediately.

CRITICAL: Execute document-reviewer — it is the quality gate for document accuracy.

Workflow Overview

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

Scope Boundaries

Included in this skill:

• Existing document identification and selection
• Change content clarification
• 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

Discover the existing documents under docs/design/, docs/prd/, and docs/adr/.

Decision flow:

Step 2: Document Type and Layer Determination

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

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

Determine which sections need updating, the reason for the change, and the expected outcome after the update. Derive them from the request and the target document. Use AskUserQuestion only for an item the request and document leave undetermined, and only when a different answer would change which sections are updated or what the update must achieve.

Pass the resulting items, covered sections, and any stated total size budget to update or revision agents. Before the next approval gate, map every diff hunk to an approved item or required consistency update; request a scope decision for unmapped or over-budget changes.

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
  [Step 3 statements for the sections to update, reason, and expected outcome, copied verbatim]

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

Step 5: Document Review

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 with the applicable exact shape:

• Design Doc: doc_type: DesignDoc, target: [path from Step 1], review_context: update, and verification_evidence: $CODE_VERIFICATION_OUTPUT.
• PRD: doc_type: PRD and target: [path from Step 1].
• ADR: doc_type: ADRBatch, targets: [path from Step 1], and review_context: update.

For each type, review consistency of the changed sections and their dependent statements, governing requirements, and change history.

Store output as: $STEP_5_OUTPUT

On review result:

• Approved → Proceed to Step 6
• Needs revision → Apply the Review Resolution Gate. Return to Step 4 when apply findings exist, using the following prompt:

  subagent_type: [Update Agent from Step 2]
  description: "Revise [Type from Step 2]"
  prompt: |
    Operation Mode: update
    Existing Document: [path from Step 1]
  
    ## Adjudicated Review Findings
    [complete reviewer finding objects verbatim, with only their orchestrator dispositions added]
  
    Treat these findings as the complete revision scope and preserve adjacent content.
  

• On re-review pass prior_feedback as [{id, disposition, reason?, evidence}]
• All actionable findings are decline and every user_decision_required item is resolved → Proceed to Step 6

Step 6: Consistency Verification and Final Approval [Stop: Final approval]

For Design Doc only, invoke design-sync first:

subagent_type: design-sync
description: "Verify consistency"
prompt: "source_design: [path from Step 1]"

When conflicts are detected, apply the Review Resolution Gate using design-sync as a fresh verifier. Return apply conflicts to Step 4 for the owning document, rerun design-sync after correction, retain evidenced declines as complete, and request user input for user_decision_required or the Gate's escalation conditions.

For every document type, present the updated document, the review outcome, any resolved declines, and the sync result when one ran. This is the only approval gate in the flow: wait for the user's decision before completing.

Error Handling

Completion Criteria

• Identified target document
• Change content determined from the request, the document, or a question whose answer changed the update
• 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

When findings were declined during review, append their IDs, governing reasons, and evidence to this completion response.
