Recipe Design Skill for Claude

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 the design phase.

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. The scope bootstrap locates seed files; the named specialists own semantic investigation and artifact authorship.

Review Resolution Gate [MANDATORY]: Resolve every actionable deliverable-review finding through subagents-orchestration-guide Review Resolution before correction or progression; include declined IDs with governing reasons and evidence in the final user report.

Before the first finding disposition, read references/review-resolution.md from the loaded subagents-orchestration-guide skill.

Execution Protocol:

• Invoke named specialists for deliverable production — pass data between them and validate their results. Step 1 is a recipe-local read-only scope bootstrap limited to locating seed files.
• 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
• Scope: Complete when design documents receive approval

subagents-orchestration-guide usage: Use the guide for orchestration principles (Delegation Boundary, Decision precedence, Execution Boundary), the Scale Determination table, and handoff contracts HC-02 onward. This recipe's start order and subagent prompts supersede the guide's requirement-analyzer-origin flow, First Action Rule, HC-01, and Agent-Specific Prompt Content.

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.

Workflow Overview

Requirements → scope bootstrap → codebase-analyzer → [Stop: Scope confirmation]
                                                            ↓
                                                    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:

• Extract candidate keywords from the user requirements (feature names, domain nouns, identifiers).
• Search the repository with Bash (rg, or grep when rg is unavailable) for files matching those keywords.
• Collect the matched file paths as the seed affectedFiles.
• 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.
• 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.

Execute Skill: requirement-convergence before running the hearing protocol.

First run the requirement-convergence hearing protocol, using the codebase-analyzer findings as the facts it presents. In this flow, the orchestrator elicits and judges the fields and records the result as the skill's convergence object (outcome, requirements[] with layer labels, nonGoals[], plus a readiness label per field). Treat cost as already resolved because semantic repository investigation is assigned to codebase-analyzer and entering this recipe decided to design. Carry that object into Step 4 so technical-designer persists it to the Design Doc.

Then present, sourced from the codebase-analyzer JSON, using AskUserQuestion:

• 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). ADRs use alternative comparison; Design Docs use Design Convergence.

• 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 and user answers: [Step 3 confirmed scope and user answers]. Convergence result: [Step 3 convergence object]. Apply the code: prefix to codebase-analyzer fact_ids when filling the Fact Disposition Table."
• 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 and user answers: [Step 3 confirmed scope and user answers]. 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."
• (Design Doc only) Invoke document-reviewer to verify consistency, completeness, and adopted design validity
• Treat the preceding code-verifier result as code_verification evidence; the document-reviewer result controls correction routing.
• subagent_type: "dev-workflows-fullstack:document-reviewer", description: "Design Doc review", prompt: "Review [Design Doc path] for consistency, completeness, and adopted design validity. doc_type: DesignDoc. review_context: creation. requirements_verbatim: [user requirements verbatim]. confirmed_decisions: [Step 3 confirmed scope and user answers]. codebase_analysis: [codebase-analyzer JSON from Step 2]. code_verification: [code-verifier output from this step]"
• Apply the Review Resolution Gate. When apply findings change the Design Doc, invoke technical-designer in update mode, then re-run code-verifier and document-reviewer with prior_feedback.
• (ADR only) Invoke document-reviewer to verify consistency and completeness
• subagent_type: "dev-workflows-fullstack:document-reviewer", description: "ADR review", prompt: "Review [ADR path] for consistency and completeness. doc_type: ADR. codebase_analysis: [codebase-analyzer JSON from Step 2]"
• Apply the Review Resolution Gate. When apply findings change the ADR, invoke technical-designer in update mode and re-run document-reviewer with prior_feedback.
• (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."
• Apply the Review Resolution Gate to every reported conflict.
• One or more apply findings → invoke the named technical designer for each affected Design Doc; re-run code-verifier and document-reviewer for each modified document with the latest verification and prior_feedback, then re-run design-sync
• Every actionable conflict is decline → proceed to the approval stop
• Any unresolved user_decision_required conflict → stop for user input

[STOP]: Present the design document, plus design-sync results for a Design Doc, and obtain user approval. For an approved ADR, invoke technical-designer in update mode to set its status to Accepted and verify the update before completion.
