# Greenfield Workflow

Workflow for new projects built from scratch. Flows linearly: Problem → Research → Plan → UI Design (if applicable) → Test Spec → Decompose → Implement + Product Completeness Gate → Code Testability Revision → Decompose Tests → Implement Tests → Run Tests → Test-Spec Sync → Update Docs → Security Audit (optional) → Performance Test (optional) → Deploy → Retrospective.

## Detection Rules

**Resolution**: when a state file exists, `state.step` + `state.status` drive detection and the conditions below are not consulted. When no state file exists (cold start), walk the rules in order — first folder-probe match wins. Steps without a folder probe are state-driven only; they can only be reached by auto-chain from a prior step.

---

**Step 1 — Problem Gathering**
Condition: `_docs/00_problem/` does not exist, OR any of these are missing/empty:
- `problem.md`
- `restrictions.md`
- `acceptance_criteria.md`
- `input_data/` (must contain at least one file)

Action: Read and execute `.cursor/skills/problem/SKILL.md`

---

**Step 2 — Research (Initial)**
Condition: `_docs/00_problem/` is complete AND `_docs/01_solution/` has no `solution_draft*.md` files

Action: Read and execute `.cursor/skills/research/SKILL.md` (will auto-detect Mode A)

---

**Research Decision** (inline gate between Step 2 and Step 3)
Condition: `_docs/01_solution/` contains `solution_draft*.md` files AND `_docs/01_solution/solution.md` does not exist AND `_docs/02_document/architecture.md` does not exist

Action: Present the current research state to the user:
- How many solution drafts exist
- Whether tech_stack.md and security_analysis.md exist
- One-line summary from the latest draft

Then present using the **Choose format**:

```
══════════════════════════════════════
 DECISION REQUIRED: Research complete — next action?
══════════════════════════════════════
 A) Run another research round (Mode B assessment)
 B) Proceed to planning with current draft
══════════════════════════════════════
 Recommendation: [A or B] — [reason based on draft quality]
══════════════════════════════════════
```

- If user picks A → Read and execute `.cursor/skills/research/SKILL.md` (will auto-detect Mode B)
- If user picks B → auto-chain to Step 3 (Plan)

---

**Step 3 — Plan**
Condition: `_docs/01_solution/` has `solution_draft*.md` files AND `_docs/02_document/architecture.md` does not exist

Action:
1. The plan skill's Prereq 2 will rename the latest draft to `solution.md` — this is handled by the plan skill itself
2. Read and execute `.cursor/skills/plan/SKILL.md`

If `_docs/02_document/` exists but is incomplete (has some artifacts but no `FINAL_report.md`), the plan skill's built-in resumability handles it.

---

**Step 4 — UI Design (conditional)**
Condition (folder fallback): `_docs/02_document/architecture.md` exists AND `_docs/02_document/tests/traceability-matrix.md` does not exist.
State-driven: reached by auto-chain from Step 3.

Action: Read and execute `.cursor/skills/ui-design/SKILL.md`. The skill runs its own **Applicability Check**, which handles UI project detection and the user's A/B choice. It returns one of:

- `outcome: completed` → mark Step 4 as `completed`, auto-chain to Step 5 (Test Spec).
- `outcome: skipped, reason: not-a-ui-project` → mark Step 4 as `skipped`, auto-chain to Step 5.
- `outcome: skipped, reason: user-declined` → mark Step 4 as `skipped`, auto-chain to Step 5.

The autodev no longer inlines UI detection heuristics — they live in `ui-design/SKILL.md` under "Applicability Check".

---

**Step 5 — Test Spec**
Condition (folder fallback): `_docs/02_document/FINAL_report.md` exists AND `_docs/02_document/architecture.md` exists AND `_docs/02_document/tests/traceability-matrix.md` does not exist.
State-driven: reached by auto-chain from Step 4 (completed or skipped).

Action: Read and execute `.cursor/skills/test-spec/SKILL.md`.

This step converts the greenfield problem statement, acceptance criteria, solution, architecture, component docs, and UI design artifacts (if any) into test specifications before implementation begins. The test spec should cover unit, integration, blackbox, and e2e scenarios where those levels are applicable to the project.

---

**Step 6 — Decompose**
Condition: `_docs/02_document/` contains `architecture.md` AND `_docs/02_document/components/` has at least one component AND `_docs/02_document/tests/traceability-matrix.md` exists AND `_docs/02_tasks/todo/` does not exist or has no implementation task files.

Action: Invoke `.cursor/skills/decompose/SKILL.md` for **implementation task decomposition**. The greenfield flow selects the implementation entrypoint before handing off: Bootstrap Structure, Module Layout, Component Task Decomposition, and Cross-Task Verification.

Do not invoke Blackbox Test Task Decomposition from Step 6. Test tasks are intentionally deferred to Step 9 (Decompose Tests) so the first implementation batch stays focused on product functionality and Step 8 can revise testability before test task files exist.

If `_docs/02_tasks/` subfolders have some task files already, the decompose skill's resumability handles it.

---

**Step 7 — Implement**
Condition: `_docs/02_tasks/todo/` contains implementation task files AND `_dependencies_table.md` exists AND `_docs/03_implementation/` does not contain a valid product implementation report.

Action: Invoke `.cursor/skills/implement/SKILL.md` with task selection context **Product implementation**.

The implement skill must run its **Product Implementation Completeness Gate** before it writes any final product implementation report. This gate compares completed product task specs, architecture/component promises, and actual source code so scaffold-only implementations cannot advance to Step 8. A final product implementation report without `_docs/03_implementation/implementation_completeness_cycle[N]_report.md` is incomplete and must not be treated as Step 7 completion.

If `_docs/03_implementation/` has batch reports, the implement skill detects completed tasks and continues. The FINAL report filename is context-dependent — see implement skill documentation for naming convention.

For folder fallback, **implementation task files** means task specs that are not test-only specs: exclude `*_test_infrastructure.md` and task specs whose `**Component**` or `**Epic**` identifies `Blackbox Tests`.

For folder fallback, a **product implementation report** is any `_docs/03_implementation/implementation_report_*.md` file except `_docs/03_implementation/implementation_report_tests.md` and refactor reports. It is valid for greenfield progression only when:
- the matching `_docs/03_implementation/implementation_completeness_cycle[N]_report.md` exists,
- that completeness report does not contain unresolved `FAIL` classifications, and
- `_docs/02_tasks/todo/` contains no pending implementation task files.

If a product report exists but any of those validity checks fail, treat product implementation as incomplete and stay in Step 7.

---

**Step 8 — Code Testability Revision**
Condition (folder fallback): `_docs/03_implementation/` contains a valid product implementation report, `_docs/03_implementation/implementation_completeness_cycle[N]_report.md` exists without unresolved `FAIL` classifications, `_docs/04_refactoring/01-testability-refactoring/testability_assessment.md` does not exist, `_docs/04_refactoring/01-testability-refactoring/testability_changes_summary.md` does not exist, `_docs/03_implementation/implementation_report_tests.md` does not exist, and `_docs/02_tasks/todo/` does not contain test task files.
State-driven: reached by auto-chain from Step 7.

**Purpose**: verify the newly built code can be exercised by the planned tests before writing the test suite. Greenfield code should be testable by design; this step catches accidental hardcoded paths, singletons, direct external service construction, or other implementation choices that would make meaningful tests impossible.

**Scope — MINIMAL, SURGICAL fixes**: this is not a general refactor. It is the smallest set of changes required to make the implemented code runnable under tests.

**Allowed changes** in this phase:
- Replace hardcoded URLs / file paths / credentials / magic numbers with env vars or constructor arguments.
- Extract narrow interfaces for components that need stubbing in tests.
- Add optional constructor parameters for dependency injection; default to the existing behavior so callers do not break.
- Wrap global singletons in thin accessors that tests can override.
- Split a function ONLY when necessary to stub one of its collaborators — do not split for clarity alone.

**NOT allowed** in this phase (defer to a later refactor task):
- Renaming public APIs.
- Moving code between files unless strictly required for isolation.
- Changing algorithms or business logic.
- Restructuring module boundaries or rewriting layers.

Action: Analyze the codebase against the test specs to determine whether the code can be tested as-is.

1. Read `_docs/02_document/tests/traceability-matrix.md` and all test scenario files in `_docs/02_document/tests/`.
2. For each test scenario, check whether the code under test can be exercised in isolation. Look for:
   - Hardcoded file paths or directory references
   - Hardcoded configuration values (URLs, credentials, magic numbers)
   - Global mutable state that cannot be overridden
   - Tight coupling to external services without abstraction
   - Missing dependency injection or non-configurable parameters
   - Direct file system operations without path configurability
   - Inline construction of heavy dependencies (models, clients)
3. If ALL scenarios are testable as-is:
   - Create `_docs/04_refactoring/01-testability-refactoring/`
   - Write `_docs/04_refactoring/01-testability-refactoring/testability_assessment.md` with the scenarios reviewed and outcome "Code is testable — no changes needed"
   - Mark Step 8 as `completed` with outcome "Code is testable — no changes needed"
   - Auto-chain to Step 9 (Decompose Tests)
4. If testability issues are found:
   - Create `_docs/04_refactoring/01-testability-refactoring/`
   - Write `list-of-changes.md` in that directory using the refactor skill template (`.cursor/skills/refactor/templates/list-of-changes.md`), with:
     - **Mode**: `guided`
     - **Source**: `autodev-greenfield-testability-analysis`
     - One change entry per testability issue found (change ID, file paths, problem, proposed change, risk, dependencies). Each entry must fit the allowed-changes list above; reject entries that drift into full refactor territory and log them under "Deferred refactor candidates" instead.
   - Invoke the refactor skill in **guided mode**: read and execute `.cursor/skills/refactor/SKILL.md` with the `list-of-changes.md` as input
   - Phase 3 (Safety Net) is skipped for this testability run because the test suite has not been implemented yet
   - After execution, surface `RUN_DIR/testability_changes_summary.md` to the user via the Choose format (accept / request follow-up) before auto-chaining
   - Copy or save the accepted summary as `_docs/04_refactoring/01-testability-refactoring/testability_changes_summary.md` so folder fallback can detect Step 8 completion
   - Mark Step 8 as `completed`
   - Auto-chain to Step 9 (Decompose Tests)

---

**Step 9 — Decompose Tests**
Condition (folder fallback): `_docs/02_document/tests/traceability-matrix.md` exists AND workspace contains source code files AND `_docs/03_implementation/` contains a valid product implementation report AND `_docs/03_implementation/implementation_completeness_cycle[N]_report.md` exists without unresolved `FAIL` classifications AND (`_docs/04_refactoring/01-testability-refactoring/testability_assessment.md` exists OR `_docs/04_refactoring/01-testability-refactoring/testability_changes_summary.md` exists) AND (`_docs/02_tasks/todo/` does not exist or has no test task files) AND `_docs/03_implementation/implementation_report_tests.md` does not exist.
State-driven: reached by auto-chain from Step 8.

Action: Read and execute `.cursor/skills/decompose/SKILL.md` in **tests-only mode** (pass `_docs/02_document/tests/` as input). The decompose skill will:
1. Run Step 1t (test infrastructure bootstrap)
2. Run Step 3 (blackbox/e2e-capable test task decomposition)
3. Run Step 4 (cross-verification against test coverage)

If `_docs/02_tasks/` subfolders have some task files already, the decompose skill's resumability handles it — it appends test tasks alongside existing completed implementation tasks.

---

**Step 10 — Implement Tests**
Condition (folder fallback): `_docs/02_tasks/todo/` contains test task files AND `_dependencies_table.md` exists AND `_docs/03_implementation/implementation_report_tests.md` does not exist.
State-driven: reached by auto-chain from Step 9.

Action: Invoke `.cursor/skills/implement/SKILL.md` with task selection context **Test implementation**.

The implement skill reads only test tasks from `_docs/02_tasks/todo/` and implements them.

If `_docs/03_implementation/` has batch reports, the implement skill detects completed test tasks and continues.

For folder fallback, **test task files** means `*_test_infrastructure.md` plus task specs whose `**Component**` or `**Epic**` identifies `Blackbox Tests`.

---

**Step 11 — Run Tests**
Condition (folder fallback): `_docs/03_implementation/implementation_report_tests.md` exists.
State-driven: reached by auto-chain from Step 10.

Action: Read and execute `.cursor/skills/test-run/SKILL.md`

Verifies the implemented unit, integration, blackbox, and e2e tests pass before proceeding to spec and documentation sync. This is a hard product gate, not a harness-smoke gate: e2e/blackbox tests must exercise the actual implemented system through public runtime boundaries and compare actual outputs against `_docs/00_problem/input_data/expected_results/results_report.md` or referenced machine-readable expected-result files. Stubs are allowed only for external systems outside the product boundary; missing internal product implementation must fail or block the gate and send the flow back to Implement.

---

**Step 12 — Test-Spec Sync**
State-driven: reached by auto-chain from Step 11. Requires `_docs/02_document/tests/traceability-matrix.md` to exist — if missing, mark Step 12 `skipped` (see Action below).

Action: Read and execute `.cursor/skills/test-spec/SKILL.md` in **cycle-update mode**. Pass the completed implementation task specs, completed test task specs, and implementation reports as inputs.

The skill appends implementation-learned acceptance criteria, scenarios, and NFR updates to the existing test-spec files without rewriting unaffected sections. If `traceability-matrix.md` is missing, mark Step 12 as `skipped` — the next `/test-spec` full run will regenerate it.

After completion, auto-chain to Step 13 (Update Docs).

---

**Step 13 — Update Docs**
State-driven: reached by auto-chain from Step 12 (completed or skipped). Requires `_docs/02_document/` to contain existing documentation — if missing, mark Step 13 `skipped` (see Action below).

Action: Read and execute `.cursor/skills/document/SKILL.md` in **Task mode**. Pass all completed implementation and test task spec files plus the implementation reports.

The document skill in Task mode updates affected module docs, component docs, system-level docs, and test documentation without redoing full discovery, verification, or problem extraction.

If `_docs/02_document/` does not contain existing docs, mark Step 13 as `skipped`.

After completion, auto-chain to Step 14 (Security Audit).

---

**Step 14 — Security Audit (optional)**
State-driven: reached by auto-chain from Step 13 (completed or skipped).

Action: Apply the **Optional Skill Gate** (`protocols.md` → "Optional Skill Gate") with:
- question:        `Run security audit before deploy?`
- option-a-label:  `Run security audit (recommended for production deployments)`
- option-b-label:  `Skip — proceed directly to deploy`
- recommendation:  `A — catches vulnerabilities before production`
- target-skill:    `.cursor/skills/security/SKILL.md`
- next-step:       Step 15 (Performance Test)

---

**Step 15 — Performance Test (optional)**
State-driven: reached by auto-chain from Step 14 (completed or skipped).

Action: Apply the **Optional Skill Gate** (`protocols.md` → "Optional Skill Gate") with:
- question:        `Run performance/load tests before deploy?`
- option-a-label:  `Run performance tests (recommended for latency-sensitive or high-load systems)`
- option-b-label:  `Skip — proceed directly to deploy`
- recommendation:  `A or B — base on whether acceptance criteria include latency, throughput, or load requirements`
- target-skill:    `.cursor/skills/test-run/SKILL.md` in **perf mode** (the skill handles runner detection, threshold comparison, and its own A/B/C gate on threshold failures)
- next-step:       Step 16 (Deploy)

---

**Step 16 — Deploy**
State-driven: reached by auto-chain from Step 15 (after Step 15 is completed or skipped).

Action: Read and execute `.cursor/skills/deploy/SKILL.md`.

After the deploy skill completes successfully, mark Step 16 as `completed` and auto-chain to Step 17 (Retrospective).

---

**Step 17 — Retrospective**
State-driven: reached by auto-chain from Step 16.

Action: Read and execute `.cursor/skills/retrospective/SKILL.md` in **cycle-end mode**. This closes the cycle's feedback loop by folding metrics into `_docs/06_metrics/retro_<date>.md` and appending the top-3 lessons to `_docs/LESSONS.md`.

After retrospective completes, mark Step 17 as `completed` and enter "Done" evaluation.

---

**Done**
State-driven: reached by auto-chain from Step 17. (Sanity check: `_docs/04_deploy/` should contain all expected artifacts — containerization.md, ci_cd_pipeline.md, environment_strategy.md, observability.md, deployment_procedures.md, deploy_scripts.md.)

Action: Report project completion with summary. Then **rewrite the state file** so the next `/autodev` invocation enters the feature-cycle loop in the existing-code flow:

```
flow: existing-code
step: 9
name: New Task
status: not_started
sub_step:
  phase: 0
  name: awaiting-invocation
  detail: ""
retry_count: 0
cycle: 1
```

On the next invocation, Flow Resolution rule 1 reads `flow: existing-code` and re-entry flows directly into existing-code Step 9 (New Task).
