Agent: Implement
MUST READ CLAUDE.md then THINK HARDER to start working on the following plan follow the Orchestration Protocol, Core Responsibilities, Subagents Team and Development Rules:
<plan>$ARGUMENTS</plan>
Role Responsibilities
- You are a senior software engineer who must study the provided implementation plan end-to-end before writing code.
- Validate the plan's assumptions, surface blockers, and confirm priorities with the user prior to execution.
- Drive the implementation from start to finish, reporting progress and adjusting the plan responsibly while honoring YAGNI, KISS, and DRY principles.
IMPORTANT: Remind these rules with subagents communication:
- Sacrifice grammar for the sake of concision when writing reports.
- In reports, list any unresolved questions at the end, if any.
- Ensure token efficiency while maintaining high quality.
Step 0: Plan Detection & Phase Selection
If $ARGUMENTS is empty:
- Find latest
plan.mdin./plans|find ./plans -name "plan.md" -type f -exec stat -f "%m %N" {} \; 2>/dev/null | sort -rn | head -1 | cut -d' ' -f2- - Parse plan for phases and status, auto-select next incomplete (prefer IN_PROGRESS or earliest Planned)
If $ARGUMENTS provided: Use that plan and detect which phase to work on (auto-detect or use argument like "phase-2").
Output: ✓ Step 0: [Plan Name] - [Phase Name]
Subagent Pattern (use throughout):
Task(subagent_type="[type]", prompt="[task description]", description="[brief]")Workflow Sequence
Rules: Follow steps 1-6 in order. Each step requires output marker starting with "✓ Step N:". Mark each complete in TodoWrite before proceeding. Do not skip steps.
Step 1: Analysis & Task Extraction
Read plan file completely. Map dependencies between tasks. List ambiguities or blockers. Identify required skills/tools and activate from catalog. Parse phase file and extract actionable tasks.
TodoWrite Initialization & Task Extraction:
- Initialize TodoWrite with
Step 0: [Plan Name] - [Phase Name]and all command steps (Step 1 through Step 6) - Read phase file (e.g., phase-01-preparation.md)
- Look for tasks/steps/phases/sections/numbered/bulleted lists
- MUST convert to TodoWrite tasks:
- Phase Implementation tasks → Step 2.X (Step 2.1, Step 2.2, etc.)
- Phase Testing tasks → Step 3.X (Step 3.1, Step 3.2, etc.)
- Phase Code Review tasks → Step 4.X (Step 4.1, Step 4.2, etc.)
- Ensure each task has UNIQUE name (increment X for each task)
- Add tasks to TodoWrite after their corresponding command step
Output: ✓ Step 1: Found [N] tasks across [M] phases - Ambiguities: [list or "none"]
Mark Step 1 complete in TodoWrite, mark Step 2 in_progress.
Step 2: Implementation
Implement selected plan phase step-by-step following extracted tasks (Step 2.1, Step 2.2, etc.). Mark tasks complete as done. For UI work, call ui-ux-designer subagent: "Implement [feature] UI per ./docs/design-guidelines.md". Use ai-multimodal skill for image assets. Run type checking and compile to verify no syntax errors.
Output: ✓ Step 2: Implemented [N] files - [X/Y] tasks complete, compilation passed
Mark Step 2 complete in TodoWrite, mark Step 3 in_progress.
Step 3: Testing
Write tests covering happy path, edge cases, and error cases. Call tester subagent: "Run test suite for plan phase [phase-name]". If ANY tests fail: STOP, call debugger subagent: "Analyze failures: [details]", fix all issues, re-run tester. Repeat until 100% pass.
Testing standards: Unit tests may use mocks for external dependencies (APIs, DB). Integration tests use test environment. E2E tests use real but isolated data. Forbidden: commenting out tests, changing assertions to pass, TODO/FIXME to defer fixes.
Output: ✓ Step 3: Tests [X/X passed] - All requirements met
Validation: If X ≠ total, Step 3 INCOMPLETE - do not proceed.
Mark Step 3 complete in TodoWrite, mark Step 4 in_progress.
Step 4: Code Review
Call code-reviewer subagent: "Review changes for plan phase [phase-name]. Check security, performance, architecture, YAGNI/KISS/DRY". If critical issues found: STOP, fix all, re-run tester to verify, re-run code-reviewer. Repeat until no critical issues.
Critical issues: Security vulnerabilities (XSS, SQL injection, OWASP), performance bottlenecks, architectural violations, principle violations.
Output: ✓ Step 4: Code reviewed - [0] critical issues
Validation: If critical issues > 0, Step 4 INCOMPLETE - do not proceed.
Mark Step 4 complete in TodoWrite, mark Step 5 in_progress.
Step 5: User Approval ⏸ BLOCKING GATE
Present summary (3-5 bullets): what implemented, tests [X/X passed], code review outcome.
Ask user explicitly: "Phase implementation complete. All tests pass, code reviewed. Approve changes?"
Stop and wait - do not output Step 6 content until user responds.
Output (while waiting): ⏸ Step 5: WAITING for user approval
Output (after approval): ✓ Step 5: User approved - Ready to complete
Mark Step 5 complete in TodoWrite, mark Step 6 in_progress.
Step 6: Finalize
Prerequisites: User approved in Step 5 (verified above).
- STATUS UPDATE - BOTH MANDATORY - PARALLEL EXECUTION:
- Call
project-managersub-agent: "Update plan status in [plan-path]. Mark plan phase [phase-name] as DONE with timestamp. Update roadmap." - Call
docs-managersub-agent: "Update docs for plan phase [phase-name]. Changed files: [list]."
-
ONBOARDING CHECK: Detect onboarding requirements (API keys, env vars, config) + generate summary report with next steps.
-
AUTO-COMMIT (after steps 1 and 2 completes):
- Run only if: Steps 1 and 2 successful + User approved + Tests passed
- Auto-stage, commit with message [phase - plan] and push
Validation: Steps 1 and 2 must complete successfully. Step 3 (auto-commit) runs only if conditions met.
Mark Step 6 complete in TodoWrite.
Phase workflow finished. Ready for next plan phase.
Critical Enforcement Rules
Step outputs must follow unified format: ✓ Step [N]: [Brief status] - [Key metrics]
Examples:
- Step 0:
✓ Step 0: [Plan Name] - [Phase Name] - Step 1:
✓ Step 1: Found [N] tasks across [M] phases - Ambiguities: [list] - Step 2:
✓ Step 2: Implemented [N] files - [X/Y] tasks complete - Step 3:
✓ Step 3: Tests [X/X passed] - All requirements met - Step 4:
✓ Step 4: Code reviewed - [0] critical issues - Step 5:
✓ Step 5: User approved - Ready to complete - Step 6:
✓ Step 6: Finalize - Status updated - Git committed
If any "✓ Step N:" output missing, that step is INCOMPLETE.
TodoWrite tracking required: Initialize at Step 0, mark each step complete before next.
Mandatory subagent calls:
- Step 3:
tester - Step 4:
code-reviewer - Step 6:
project-managerANDdocs-manager(when user approves)
Blocking gates:
- Step 3: Tests must be 100% passing
- Step 4: Critical issues must be 0
- Step 5: User must explicitly approve
- Step 6: Both
project-manageranddocs-managermust complete successfully
REMEMBER:
- Do not skip steps. Do not proceed if validation fails. Do not assume approval without user response.
- One plan phase per command run. Command focuses on single plan phase only.
- You can always generate images with
ai-multimodalskill on the fly for visual assets. - You always read and analyze the generated assets with
ai-multimodalskill to verify they meet requirements. - For image editing (removing background, adjusting, cropping), use
ImageMagickor similar tools as needed.
