Recipe Design

Context: Dedicated to the design phase.

Orchestrator Definition

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

Execution Protocol:

1. Delegate all work to sub-agents — your role is to invoke sub-agents, pass data between them, and report results. The one exception is the Step 1 scope bootstrap, a recipe-local orchestrator task limited to locating seed files.
2. Run the design flow below in order:
   • Execute: scope bootstrap → codebase-analyzer → [Stop: Scope confirmation] → technical-designer → code-verifier → document-reviewer → design-sync
   • code-verifier and design-sync apply when the design output is a Design Doc; both are skipped for ADR-only
   • Stop at every [Stop: ...] marker → Wait for user approval before proceeding
3. Scope: Complete when design documents receive approval

subagents-orchestration-guide usage: Reference the guide only for orchestration principles (Delegation Boundary, Decision precedence, permitted tools), the Scale Determination table, and handoff contracts HC-02 onward. This recipe defines its own start order and subagent prompts. The guide's requirement-analyzer-origin flow, First Action Rule, HC-01, and Call Examples do not apply to this recipe.

CRITICAL: Execute document-reviewer, design-sync (for Design Docs), and all stopping points — each serves as a quality gate. Skipping any step risks undetected inconsistencies.

                                                            ↓
                                                    technical-designer
                                                            ↓
                                                    code-verifier → document-reviewer
                                                            ↓
                                                       design-sync → [Stop: Design approval]

Scope Boundaries

Included in this skill:

• Scope bootstrap: locating seed files so codebase-analyzer receives a populated input
• Codebase analysis with codebase-analyzer (entry point of the design phase)
• Scope confirmation with the user, grounded in codebase-analyzer findings
• ADR creation (if architecture changes, new technology, or data flow changes)
• Design Doc creation with technical-designer
• Design Doc verification with code-verifier (before document review)
• Document review with document-reviewer
• Design Doc consistency verification with design-sync

Responsibility Boundary: This skill completes with design document (ADR/Design Doc) approval. Work planning and beyond are outside scope.

Execution Flow

Requirements: $ARGUMENTS

Step 1: Scope Bootstrap

codebase-analyzer requires a populated requirement_analysis.affectedFiles. Build that seed with a lightweight, orchestrator-local pass — locating files only, with no deep reading and no design decisions:

1. Extract candidate keywords from the user requirements (feature names, domain nouns, identifiers).
2. Search the repository with Bash (rg, or grep when rg is unavailable) for files matching those keywords.
3. Collect the matched file paths as the seed affectedFiles.
4. When the search returns no files: ask the user which files or modules the design targets (AskUserQuestion), and use that answer as affectedFiles before invoking codebase-analyzer. If the user confirms no related code exists, report that codebase-grounded design does not apply and confirm with the user how to proceed.
5. When the search returns more than ~20 files: the keywords are too broad for a focused design scope. Present the most relevant candidates to the user (AskUserQuestion) and confirm the seed affectedFiles before invoking codebase-analyzer.

This step locates seed files only. Reading files in full, tracing dependencies, and analysis remain codebase-analyzer's responsibility.

Step 2: Codebase Analysis

Invoke codebase-analyzer with its existing schema. The orchestrator constructs requirement_analysis from the Step 1 seed.

• Invoke codebase-analyzer using Agent tool
  • subagent_type: "dev-workflows-fullstack:codebase-analyzer", description: "Codebase analysis"
  • prompt: include
    • requirements: the user requirements verbatim
    • requirement_analysis: a JSON object with all four fields — affectedFiles (Step 1 seed), purpose (the user requirements), scale (provisional value from the Scale Determination table applied to the seed file count), technicalConsiderations ({ constraints: [], risks: [], dependencies: [] } — the bootstrap performs no analysis, so the object is present with empty lists)
    • Expected action: analyze the seed files and produce design guidance

Step 3: Scope Confirmation

After codebase-analyzer returns, confirm the design scope with the user before any design work. This is a recipe-local confirmation step. Use AskUserQuestion.

Present, sourced from the codebase-analyzer JSON:

• Target files/modules: analysisScope.filesAnalyzed and the modules they belong to
• Affected layers: layers touched, derived from analysisScope.categoriesDetected and focusAreas
• Unknowns/assumptions: limitations plus any assumptions codebase-analyzer recorded
• Questions before design: open points that need a user answer before design proceeds

Ask the user to choose one:

• Proceed to design with this scope — continue to Step 4 (Design Doc)
• Correct the scope and re-run — return to Step 1 with the corrected scope; when the user names the corrected files or modules, use those directly as the Step 1 seed instead of re-deriving them by search
• Hold additional hearing, then proceed — gather the missing answers, then continue to Step 4
• Produce an ADR — when the confirmed scope involves architecture changes, new technology, or data flow changes, continue to Step 4 with technical-designer in ADR mode

After the user confirms the scope, count the confirmed target files and set the scale from the subagents-orchestration-guide Scale Determination table. This confirmed scale supersedes the Step 2 provisional value and determines the design document.

[STOP]: Wait for the user's choice before proceeding.

Step 4: Design Document Creation

Pass the full codebase-analyzer JSON to technical-designer (handoff contract HC-02). technical-designer presents at least two design alternatives with trade-offs for each.

• Invoke technical-designer using Agent tool
  • For Design Doc: subagent_type: "dev-workflows-fullstack:technical-designer", description: "Design Doc creation", prompt: "Create Design Doc based on the requirements. Requirements: [user requirements verbatim]. Codebase analysis: [codebase-analyzer JSON from Step 2]. Confirmed scope: [Step 3 confirmed scope]. Apply the code: prefix to codebase-analyzer fact_ids when filling the Fact Disposition Table. Present at least two architecture alternatives with trade-offs."
  • For ADR: subagent_type: "dev-workflows-fullstack:technical-designer", description: "ADR creation", prompt: "Create ADR for [technical decision]. Requirements: [user requirements verbatim]. Codebase analysis: [codebase-analyzer JSON from Step 2]. Confirmed scope: [Step 3 confirmed scope]. Present at least two alternatives with trade-offs."
• (Design Doc only) Invoke code-verifier to verify the Design Doc against existing code. Skip for ADR.
  • subagent_type: "dev-workflows-fullstack:code-verifier", description: "Design Doc verification", prompt: "doc_type: design-doc document_path: [Design Doc path] Verify Design Doc against existing code."
• Invoke document-reviewer to verify consistency (pass code-verifier results for Design Doc; omit for ADR)
  • subagent_type: "dev-workflows-fullstack:document-reviewer", description: "Document review", prompt: "Review [document path] for consistency and completeness. codebase_analysis: [codebase-analyzer JSON from Step 2]. code_verification: [code-verifier output from this step] (Design Doc only)"
• (Design Doc only) Invoke design-sync to verify consistency across design documents. Skip for ADR-only.
  • subagent_type: "dev-workflows-fullstack:design-sync", description: "Design consistency check", prompt: "Check consistency across all Design Docs in docs/design/. Report conflicts and overlaps."

[STOP]: Present the design document, plus design-sync results for a Design Doc, and obtain user approval.
