Core Mission

• Success Criteria:
  • All features have complete spec files (spec.json, requirements.md, design.md, tasks.md)
  • Dependency ordering respected (upstream specs complete before downstream)
  • Independent features processed in parallel via subagent dispatch
  • Cross-spec consistency verified (data models, interfaces, naming)
  • Mixed roadmap context understood without breaking ## Specs (dependency order) parsing
  • Controller context stays lightweight (subagents do the heavy work)

Execution Steps

Step 1: Read Roadmap and Validate

1. Read .kiro/steering/roadmap.md
2. Parse the ## Specs (dependency order) section to extract:
   • Feature names
   • One-line descriptions
   • Dependencies for each feature
   • Completion status ([x] = done, [ ] = pending)
3. If present, also read for context:
   • ## Existing Spec Updates
   • ## Direct Implementation Candidates Do not include these in dependency-wave execution; they are awareness-only inputs for sequencing and consistency review.
4. For each pending feature in ## Specs (dependency order), verify .kiro/specs/<feature>/brief.md exists
5. If any brief.md is missing, stop and report: "Missing brief.md for: [list]. Run /buildpad-discovery to generate briefs first."

Step 2: Build Dependency Waves

Group pending features into waves based on dependencies:

• Wave 1: Features with no dependencies (or all dependencies already completed [x])
• Wave 2: Features whose dependencies are all in Wave 1 or already completed
• Wave N: Features whose dependencies are all in earlier waves or already completed

Display the execution plan:

Spec Batch Plan:
  Wave 1 (parallel): app-foundation
  Wave 2 (parallel): block-editor, page-management
  Wave 3 (parallel): sidebar-navigation, database-views
  Wave 4 (parallel): cli-integration
  Total: 6 specs across 4 waves

If roadmap contains ## Existing Spec Updates or ## Direct Implementation Candidates, mention them separately as non-batch items so the user can see the whole decomposition.

Step 3: Execute Waves

For each wave, dispatch all features in the wave as parallel subagents via the Agent tool.

For each feature in the wave, dispatch a subagent with this prompt:

Create a complete specification for feature "{feature-name}".

1. Read the brief at .kiro/specs/{feature-name}/brief.md for feature context
2. Read the roadmap at .kiro/steering/roadmap.md for project context
3. Execute the full spec pipeline. For each phase, read the corresponding skill's SKILL.md for complete instructions (templates, rules, review gates):
   a. Initialize: Read .claude/skills/buildpad-spec-init/SKILL.md, then create spec.json and requirements.md
   b. Generate requirements: Read .claude/skills/buildpad-spec-requirements/SKILL.md, then follow its steps
   c. Generate design: Read .claude/skills/buildpad-spec-design/SKILL.md, then follow its steps
   d. Generate tasks: Read .claude/skills/buildpad-spec-tasks/SKILL.md, then follow its steps
4. Set all approvals to true in spec.json (auto-approve mode, equivalent of -y flag)
5. Report completion with file list and task count

After all subagents in the wave complete:

1. Verify each feature has: spec.json, requirements.md, design.md, tasks.md
2. If any feature failed, report the error and continue with features that succeeded
3. Display wave completion: "Wave N complete: [features]. Files verified."
4. Proceed to next wave

Step 4: Cross-Spec Review

After all waves complete, dispatch a single subagent for cross-spec consistency review. This is the highest-value quality gate -- it catches issues that per-spec review gates cannot.

Subagent prompt:

You are a cross-spec reviewer. Read ALL generated specs and check for consistency across the entire project.

Read these files for every feature in the roadmap:
- .kiro/specs/*/design.md (primary: contains interfaces, data models, architecture)
- .kiro/specs/*/requirements.md (for scope and acceptance criteria)
- .kiro/specs/*/tasks.md (for boundary annotations only -- read _Boundary:_ lines, skip task descriptions)
- .kiro/steering/roadmap.md

Reading priority: Focus on design.md files (they contain interfaces, data models, architecture). For requirements.md, focus on section headings and acceptance criteria. For tasks.md, focus on _Boundary:_ annotations.

Check the following:

1. **Data model consistency**: Do all specs that reference the same entities (tables, types, interfaces) define them consistently? Are field names, types, and relationships aligned?

2. **Interface alignment**: Where spec A produces output that spec B consumes (APIs, events, shared state), do the contracts match exactly? Are request/response shapes, event payloads, and error codes consistent?

3. **No duplicate functionality**: Is any capability specified in more than one spec? Flag overlaps.

4. **Dependency completeness**: Does every spec's design.md reference the correct upstream specs? Are there implicit dependencies not declared in roadmap.md?

5. **Naming conventions**: Are component names, file paths, API routes, and database table names consistent across all specs?

6. **Shared infrastructure**: Are shared concerns (authentication, error handling, logging, configuration) handled in one spec and correctly referenced by others?

7. **Task boundary alignment**: Do task _Boundary:_ annotations across specs partition the codebase cleanly? Are there files claimed by multiple specs?
8. **Roadmap boundary continuity**: If roadmap includes `Existing Spec Updates` or `Direct Implementation Candidates`, do the generated new specs avoid absorbing that work by accident?
9. **Architecture boundary integrity**: Do the specs preserve clean responsibility seams, avoid shared ownership, keep dependency direction coherent, and include enough revalidation triggers to catch downstream impact?
10. **Change-friendly decomposition**: Has any spec absorbed multiple independent seams that should probably be split instead of kept together?

Output format:
- CONSISTENT: [list areas that are well-aligned]
- ISSUES: [list each issue with: which specs, what's inconsistent, suggested fix]
- If no issues found: "All specs are consistent. Ready for implementation."

After the review subagent returns:

• Critical/important issues found: Dispatch fix subagents for each affected spec to apply the suggested fixes. If the issue is really a decomposition problem (for example boundary overlap or one spec carrying multiple independent seams), stop and return to roadmap/discovery instead of papering over it locally. Re-run cross-spec review after fixes (max 3 remediation rounds).
• Minor issues only: Report them for user awareness, proceed to Step 5.
• No issues: Proceed to Step 5.

Step 5: Finalize

1. Glob .kiro/specs/*/tasks.md to verify all specs exist
2. For each completed spec, read spec.json to confirm phase and approvals
3. Update roadmap.md: mark completed specs as [x]
4. If roadmap.md includes Existing Spec Updates or Direct Implementation Candidates, leave them untouched and mention them as remaining follow-up items unless already explicitly completed elsewhere

Display final summary:

Spec Batch Complete:
  ✓ app-foundation: X requirements, Y design components, Z tasks
  ✓ block-editor: ...
  ✓ page-management: ...
  ...
  Total: N specs created, M tasks generated
  Cross-spec review: PASSED / N issues found (M fixed)
  Existing spec updates pending: <count or none>
  Direct implementation candidates pending: <count or none>

Next: Review generated specs, then start implementation with /buildpad-impl <feature>

Critical Constraints

• Controller stays lightweight: Only read roadmap.md and brief.md existence checks in main context. All spec generation happens in subagents.
• Wave ordering is strict: Never start a wave until all features in previous waves are complete.
• Parallel within waves: All features in the same wave MUST be dispatched in parallel via Agent tool, not sequentially.
• No partial waves: If a feature in a wave fails, still complete the other features in that wave before reporting.
• Skip completed specs: Features with [x] in roadmap.md or existing tasks.md are skipped.
• ## Specs (dependency order) remains authoritative for batch execution: Other roadmap sections are context, not wave inputs.

Safety & Fallback

Subagent failure:

• Log the error, skip the failed feature
• Continue with remaining features in the wave
• Report failed features in the summary
• Suggest: "Run /buildpad-spec-quick <feature> --auto manually for failed features."

Circular dependencies:

• If dependency graph has cycles, report the cycle and stop
• Suggest: "Fix dependency ordering in roadmap.md"

Roadmap not found:

• Stop and report: "No roadmap.md found. Run /buildpad-discovery first."
