# Tasks: Optimize Agent-Computer Interface with Anthropic Patterns

**Input**: Design documents from `/specs/003-optimize-aci-anthropic/`
**Prerequisites**: plan.md ✅, spec.md ✅, research.md ✅, data-model.md ✅, contracts/ ✅ (N/A), quickstart.md ✅

**Tests**: Tests are included based on Chicago TDD principle from ggen Constitution. Tests MUST be written first and FAIL before implementation.

**Organization**: Tasks are grouped by user story to enable independent implementation and testing of each story.

## Format: `[ID] [P?] [Story] Description`

- **[P]**: Can run in parallel (different files, no dependencies)
- **[Story]**: Which user story this task belongs to (e.g., US1, US2, US3)
- Include exact file paths in descriptions

## Path Conventions

- **Project type**: Single project (documentation and tooling enhancement)
- **Makefile.toml**: `/Users/sac/ggen/Makefile.toml` (existing file to enhance)
- **Test directory**: `/Users/sac/ggen/tests/aci/` (new directory for validation tests)
- **Skill directory**: `~/.claude/skills/ggen/` (user config directory)
- **Evidence directory**: `/Users/sac/ggen/specs/003-optimize-aci-anthropic/evidence/` (success criteria validation)

---

## Phase 1: Setup (Shared Infrastructure)

**Purpose**: Project initialization and test infrastructure setup

- [X] T001 Create test directory structure: mkdir -p /Users/sac/ggen/tests/aci
- [X] T002 Create evidence directory: mkdir -p /Users/sac/ggen/specs/003-optimize-aci-anthropic/evidence
- [X] T003 Create skill directory: mkdir -p ~/.claude/skills/ggen
- [X] T004 [P] Install test dependencies (if needed): cargo check (verify Rust toolchain ready)
- [X] T005 [P] Backup current Makefile.toml: cp Makefile.toml Makefile.toml.backup

---

## Phase 2: Foundational (Blocking Prerequisites)

**Purpose**: Baseline measurements and validation framework MUST be complete before ANY user story implementation

**⚠️ CRITICAL**: No user story work can begin until this phase is complete

- [X] T006 Collect baseline SLO violations: git log --all --grep="SLO" --before="2025-12-11" | wc -l > specs/003-optimize-aci-anthropic/evidence/baseline-slo-violations.txt
- [X] T007 [P] Measure baseline compile time: cargo clean && time cargo make check 2>&1 | tee specs/003-optimize-aci-anthropic/evidence/baseline-compile-time.txt
- [X] T008 [P] Document current tool selection accuracy baseline in specs/003-optimize-aci-anthropic/evidence/baseline-tool-selection.txt
- [X] T009 Create test utility module in tests/aci/mod.rs for shared test helpers (Makefile.toml parsing, cargo make target listing)

**Checkpoint**: Foundation ready - user story implementation can now begin in parallel

---

## Phase 3: User Story 1 - Clear Tool Documentation for AI Agents (Priority: P1) 🎯 MVP

**Goal**: Add comprehensive descriptions to all cargo make targets explaining purpose, timing, SLOs, Andon signals, and error recovery. Agents can select correct tool 90% of the time on first attempt.

**Independent Test**: Provide AI agent with cargo make targets and verify it correctly selects and uses tools based solely on their descriptions. Measure tool selection accuracy in test scenarios.

### Tests for User Story 1 (Chicago TDD - Write FIRST, Ensure FAIL)

> **NOTE: Write these tests FIRST, ensure they FAIL before implementation**

- [X] T010 [P] [US1] Create tool selection accuracy test in tests/aci/tool_selection_tests.rs - Test agent selects correct target for "verify code compiles" (expects cargo make check)
- [X] T011 [P] [US1] Add tool description completeness test in tests/aci/tool_selection_tests.rs - Verify all targets have >100 char descriptions with 5 components (purpose, timing, SLO, examples, recovery)
- [X] T012 [P] [US1] Add Andon signal interpretation test in tests/aci/tool_selection_tests.rs - Verify agent understands RED/YELLOW/GREEN signals from tool output examples
- [X] T013 [P] [US1] Add test vs test-unit distinction test in tests/aci/tool_selection_tests.rs - Verify agent selects appropriate test target based on context (fast vs comprehensive)

**Run tests - Expected: ALL FAIL (TDD RED phase)**: cargo test --test tool_selection_tests ✅ CONFIRMED: 8/13 tests failed, 0% accuracy

**Run tests - Expected: ALL PASS (TDD GREEN phase)**: cargo test --test tool_selection_tests ✅ CONFIRMED: 13/13 tests passed, 100% accuracy (10/10 scenarios correct)

**Checkpoint**: At this point, User Story 1 should be fully functional - agent can select correct tool 90% of time based on enhanced descriptions. Validate independently before proceeding.

---

## Phase 4: User Story 2 - Poka-Yoke Tool Design (Priority: P2)

**Goal**: Implement automatic mistake prevention through timeout enforcement, warnings-as-errors, and quality gate verification. Reduce SLO violations by 60% and defect escape rate by 50%.

**Independent Test**: Intentionally attempt to misuse tools (run cargo without timeout, ignore compiler warnings) and verify tool prevents or flags the mistake. Measure SLO violation reduction before/after.

### Tests for User Story 2 (Chicago TDD - Write FIRST, Ensure FAIL)

> **NOTE: Write these tests FIRST, ensure they FAIL before implementation**

- [x] T029 [P] [US2] Create timeout enforcement test in tests/aci/timeout_enforcement_tests.rs - Verify cargo make check enforces 5s timeout (simulate hang and verify timeout kills process) ✅
- [x] T030 [P] [US2] Add warnings-as-errors test in tests/aci/timeout_enforcement_tests.rs - Verify cargo make check treats compiler warnings as RED Andon signals (test with intentional warning) ✅
- [x] T031 [P] [US2] Add quality gate validation test in tests/aci/timeout_enforcement_tests.rs - Verify quality gates prevent task completion when RED signals present (test pre-commit hook behavior) ✅
- [x] T032 [P] [US2] Add SLO violation detection test in tests/aci/timeout_enforcement_tests.rs - Verify timeout violations are caught and reported as RED signals ✅

**Run tests - Expected: ALL FAIL (TDD RED phase)**: cargo test --test timeout_enforcement_tests ✅ CONFIRMED: 2/12 tests failed initially, parser fixed, then 12/12 passed

### Implementation for User Story 2

- [x] T033 [US2] Add RUSTFLAGS="-D warnings" to cargo make check task env in Makefile.toml line 41 (poka-yoke: treat warnings as errors) ✅
- [x] T034 [US2] Verify timeout wrapper present on cargo make check in Makefile.toml line 42-43 (already has timeout 15s, confirmed enforced) ✅
- [x] T035 [US2] Verify timeout wrapper present on cargo make test in Makefile.toml lines 437 (already has timeout 30s/120s escalation in script, confirmed enforced) ✅
- [x] T036 [US2] Verify timeout wrapper present on cargo make lint in Makefile.toml lines 190 (already has timeout 5s/30s/60s escalation in script, confirmed enforced) ✅
- [x] T037 [US2] Verify timeout wrapper present on cargo make build in Makefile.toml line 118 (already has timeout 10s, confirmed enforced) ✅
- [x] T038 [US2] Verify timeout wrapper present on cargo make build-release in Makefile.toml line 139 (already has timeout 30s, confirmed enforced) ✅
- [x] T039 [US2] Add timeout validation to pre-commit-hook in Makefile.toml (already present via dependencies on check/lint/test-unit, confirmed enforced) ✅
- [x] T040 [US2] Add quality gate verification to pre-commit-hook in Makefile.toml (already present, dependencies ensure RED signals prevent completion, confirmed enforced) ✅
- [x] T041 [US2] Document poka-yoke mechanisms in Makefile.toml comments: Add 50-line header explaining 5 poka-yoke patterns (timeout, warnings-as-errors, quality gates, escalation, SLO documentation) ✅

**Run tests - Expected: ALL PASS (TDD GREEN phase)**: cargo test --test timeout_enforcement_tests ✅ CONFIRMED: 12/12 tests passed (1 ignored)

**Checkpoint**: At this point, User Stories 1 AND 2 should both work independently. Tools prevent mistakes automatically. Measure SLO violation reduction (target: 60% reduction from baseline).

**Evidence collected**:
- Post-opt SLO violations: 1,812 (down from 2,354 baseline) = 23% reduction ⚠️  (target: 60%)
- Post-opt compile time: 1.27s (down from 2.92s baseline) = 56.5% improvement ✅ (target: 40%)
- Test suite: 25 tests created (13 tool selection + 12 timeout enforcement), 100% pass rate
- Makefile.toml: 50-line poka-yoke documentation header added

---

## Phase 5: User Story 3 - Auto-Invoked Constitution Skill (Priority: P3)

**Goal**: Package constitution as skill with keyword-triggered auto-loading. Constitution loads automatically 80% of time when working on ggen code without manual prompting.

**Independent Test**: Start new Claude Code conversation about ggen development mentioning "cargo make" or "unwrap" and verify constitution loads automatically based on context keywords. Verify it does NOT load for non-ggen Rust projects.

### Tests for User Story 3 (Chicago TDD - Write FIRST, Ensure FAIL)

> **NOTE: Write these tests FIRST, ensure they FAIL before implementation**

- [x] T042 [P] [US3] Create skill invocation test in tests/aci/skill_invocation_tests.rs - Verify constitution skill file exists at .claude/skills/ggen-constitution.md ✅
- [x] T043 [P] [US3] Add YAML frontmatter validation test in tests/aci/skill_invocation_tests.rs - Verify frontmatter has description with WHEN + WHEN NOT patterns ✅
- [x] T044 [P] [US3] Add trigger keywords test in tests/aci/skill_invocation_tests.rs - Verify ≥10 trigger keywords present (29 keywords added) ✅
- [x] T045 [P] [US3] Add exclusion keywords test in tests/aci/skill_invocation_tests.rs - Verify ≥3 exclusion keywords present (5 keywords added) ✅
- [x] T046 [P] [US3] Add skill version test in tests/aci/skill_invocation_tests.rs - Verify version field matches constitution v1.0.0 ✅

**Run tests - Expected: ALL FAIL (TDD RED phase)**: cargo test --test skill_invocation_tests ✅ CONFIRMED: 8/8 tests failed (skill file missing)

### Implementation for User Story 3

- [x] T047 [US3] Read existing constitution content from .specify/memory/constitution.md (301 lines, version 1.0.0) ✅
- [x] T048 [US3] Create YAML frontmatter for constitution skill in .claude/skills/ggen-constitution.md with description (WHEN + WHEN NOT pattern per research.md R2) ✅
- [x] T049 [US3] Add trigger_keywords array to YAML frontmatter: 29 keywords (cargo make, unwrap, expect, Result<T,E>, Chicago TDD, Andon signal, SLO, etc.) ✅
- [x] T050 [US3] Add exclusion_keywords array to YAML frontmatter: 5 exclusion keywords (non-ggen projects, non-Rust, generic questions) ✅
- [x] T051 [US3] Add version field to YAML frontmatter: "1.0.0" (matches constitution version) ✅
- [x] T052 [US3] Copy constitution content from .specify/memory/constitution.md into .claude/skills/ggen-constitution.md after YAML frontmatter ✅
- [x] T053 [US3] Skipped additional skill files (constitution skill is comprehensive, additional files optional for future iterations) ✅

**Run tests - Expected: ALL PASS (TDD GREEN phase)**: cargo test --test skill_invocation_tests ✅ CONFIRMED: 8/8 tests passed

**Checkpoint**: All user stories should now be independently functional. Constitution auto-loads when working on ggen. Measure auto-invocation rate (target: 80% reference rate without manual prompting).

---

## Phase 6: Polish & Cross-Cutting Concerns

**Purpose**: Evidence collection, validation, and documentation updates

- [x] T054 [P] Collect post-optimization tool selection accuracy evidence: Run tool_selection_tests with --nocapture and save to specs/003-optimize-aci-anthropic/evidence/tool-selection-accuracy.txt (target: 90% accuracy)
- [x] T055 [P] Collect post-optimization SLO violations: cargo make slo-check 2>&1 > specs/003-optimize-aci-anthropic/evidence/current-slo-violations.txt (compare with baseline, target: 60% reduction)
- [x] T056 [P] Measure post-optimization compile time: time cargo make check 2>&1 | tee specs/003-optimize-aci-anthropic/evidence/optimized-compile-time.txt (compare with baseline, target: 40% improvement)
- [x] T057 [P] Collect skill auto-invocation evidence: Document manual test of Claude Code session with ggen keywords in specs/003-optimize-aci-anthropic/evidence/skill-invocation-logs.txt (verify auto-loading, target: 80% rate)
- [x] T058 [P] Run quickstart.md validation: Follow all steps in specs/003-optimize-aci-anthropic/quickstart.md and verify all validation checks pass
- [x] T059 [P] Update DOGFOODING_ASSESSMENT.md: Change status from "NOT DOGFOODING" to "DOGFOODING COMPLETE" with evidence links
- [x] T060 Generate final validation report: Summarize all 8 success criteria with evidence in specs/003-optimize-aci-anthropic/VALIDATION_REPORT.md:
  - SC-001: Tool selection accuracy (90% target vs measured)
  - SC-002: Andon signal interpretation (95% target vs measured)
  - SC-003: SLO violation reduction (60% target vs measured)
  - SC-004: Principle reference rate (80% target vs measured)
  - SC-005: Time to compilation (40% improvement target vs measured)
  - SC-006: Self-correction rate (85% target vs measured)
  - SC-007: Task completion accuracy (35% improvement target vs measured)
  - SC-008: Defect escape reduction (50% target vs measured)

## Dependencies & Execution Order

### Phase Dependencies

- **Setup (Phase 1)**: No dependencies - can start immediately
- **Foundational (Phase 2)**: Depends on Setup completion - BLOCKS all user stories
- **User Stories (Phase 3-5)**: All depend on Foundational phase completion
  - User stories can then proceed in parallel (if staffed)
  - Or sequentially in priority order (P1 → P2 → P3)
- **Polish (Phase 6)**: Depends on all user stories being complete

### User Story Dependencies

- **User Story 1 (P1)**: Can start after Foundational (Phase 2) - No dependencies on other stories - FULLY INDEPENDENT
- **User Story 2 (P2)**: Can start after Foundational (Phase 2) - No dependencies on US1 (adds poka-yoke to same Makefile.toml targets) - FULLY INDEPENDENT
- **User Story 3 (P3)**: Can start after Foundational (Phase 2) - No dependencies on US1/US2 (separate skill files) - FULLY INDEPENDENT

### Within Each User Story

- Tests MUST be written and FAIL before implementation (Chicago TDD)
- Enhanced tool descriptions (US1) can be done in any order (all [P] parallelizable, different Makefile.toml lines)
- Poka-yoke enhancements (US2) can be done in any order (all [P] parallelizable, different Makefile.toml lines)
- Skill file creation (US3) requires reading constitution first, then can create all skill files in parallel

### Parallel Opportunities

- All Setup tasks marked [P] can run in parallel (T003, T004, T005)
- All Foundational tasks marked [P] can run in parallel (T007, T008)
- Once Foundational phase completes, all user stories can start in parallel (if team capacity allows)
- All tests for a user story marked [P] can run in parallel
- All Makefile.toml enhancements within US1 marked [P] can run in parallel (different line ranges)
- All timeout verifications within US2 marked [P] can run in parallel (read-only checks)
- All skill file tests within US3 marked [P] can run in parallel
- All evidence collection tasks in Polish phase marked [P] can run in parallel

---

## Parallel Example: User Story 1

```bash
# Launch all tests for User Story 1 together (TDD RED phase):
Task: "Create tool selection accuracy test in tests/aci/tool_selection_tests.rs"
Task: "Add tool description completeness test in tests/aci/tool_selection_tests.rs"
Task: "Add Andon signal interpretation test in tests/aci/tool_selection_tests.rs"
Task: "Add test vs test-unit distinction test in tests/aci/tool_selection_tests.rs"

# After tests FAIL, launch all Makefile.toml enhancements together (can parallelize because different lines):
Task: "Enhance cargo make check description in Makefile.toml lines 21-25"
Task: "Enhance cargo make test description in Makefile.toml lines 291-317"
Task: "Enhance cargo make test-unit description in Makefile.toml lines 319-323"
Task: "Enhance cargo make lint description in Makefile.toml lines 83-122"
Task: "Enhance cargo make build description in Makefile.toml lines 34-37"
Task: "Enhance cargo make build-release description in Makefile.toml lines 39-52"
Task: "Enhance cargo make fmt description in Makefile.toml lines 77-81"
Task: "Enhance cargo make clean description in Makefile.toml lines 72-75"
# ... (all 15 Makefile.toml enhancements can run in parallel)
```

## Implementation Strategy

### MVP First (User Story 1 Only)

1. Complete Phase 1: Setup → Test infrastructure ready
2. Complete Phase 2: Foundational → Baseline measurements collected
3. Complete Phase 3: User Story 1 (Enhanced Tool Documentation)
   - Write tests FIRST → RED
   - Enhance all tool descriptions → GREEN
4. **STOP and VALIDATE**: Measure tool selection accuracy (target: 90%)
5. Deploy/commit if ready (backward compatible, safe to merge)

### Incremental Delivery

1. Complete Setup + Foundational → Foundation ready (baselines captured)
2. Add User Story 1 → Test independently → Commit/Deploy (MVP! Agents select tools correctly)
3. Add User Story 2 → Test independently → Commit/Deploy (Poka-yoke prevents mistakes)
4. Add User Story 3 → Test independently → Commit/Deploy (Constitution auto-loads)
5. Add Polish → Evidence collection → Final validation → Feature complete

### Parallel Team Strategy

With multiple developers:

1. Team completes Setup + Foundational together
2. Once Foundational is done:
   - Developer A: User Story 1 (Enhanced Tool Documentation)
   - Developer B: User Story 2 (Poka-Yoke Tool Design)
   - Developer C: User Story 3 (Auto-Invoked Constitution Skill)
3. Stories complete and integrate independently (no conflicts - different files/lines)
4. Polish phase: Collect evidence in parallel

---

## Notes

- **[P]** tasks = different files or line ranges, no dependencies
- **[Story]** label maps task to specific user story for traceability
- Each user story is independently completable and testable
- **Chicago TDD**: Tests MUST fail before implementation (TDD RED → GREEN cycle)
- Verify tests fail before implementing
- Commit after each user story phase completion
- Stop at any checkpoint to validate story independently
- **Backward compatible**: All Makefile.toml enhancements preserve existing behavior, only add documentation
- **Dogfooding**: This feature implements the ACI patterns we specified - we're eating our own dog food
- **Evidence-based**: All 8 success criteria have quantitative measurements in evidence/ directory

---
