User Input

You MUST consider the user input before proceeding (if not empty).

Output

Code files are written into the project tree. The batch report is written under the provided artifact path.

batch-report.yaml   ← structured result consumed by caller

Workflow

Step 1: Verify Prerequisites (first batch only)

Confirm required artifacts exist: plan.md (with task list and Requirement Mapping table), feature spec.

Step 2: Load Context

Read from the provided artifact path and dependency artifacts. Scan the artifact directory to find these categories:

Category	Required	Purpose	Look for
Task breakdown	✅	Work items with T-IDs to implement	Artifact with task IDs (T001, T002...), may be in `tasks/` subdirectory or main planning artifact
Feature spec	✅	Requirements (REQ-XXX) and acceptance criteria	Artifact with REQ-XXX identifiers and user scenarios
Constitution	✅	Project principles and constraints	Usually named `constitution.md` in artifact root
Implementation plan	✅	Phased plan with architecture decisions	Artifact with phased sections and plan references
Architecture design	✅	API contracts, layering, package structure	Artifact with design decisions
Data model	If exists	Entity definitions, mappings, FK strategy	Artifact with schema/entity details
UX/UI spec	If exists	Screen layouts, user flows, components	Artifact with screen specs
Knowledge graph	If exists	Module dependencies and class relationships	JSON file with nodes/edges in artifact path
Checkpoints	If exists	Upstream traceability	YAML files in `checkpoints/` subdirectory
Guidelines	If exists	Migration rules and transformation patterns	Search `guidelines` skill

Step 3: Checklist Gate (first batch only)

If checklists/ directory exists, scan checklist files. If any incomplete items: display table and ask before proceeding.

Step 4: Project Setup (first batch only)

Create/verify ignore files. See references/ignore-patterns.md for patterns by language/tool.

Step 5: Match Tasks from Breakdown

From the task breakdown artifact, find tasks that match your current assignment:

Read the task breakdown (from dependency artifacts)
Match tasks by role, module/domain, or phase that align with your task description
For each matched task, extract:
- Task ID, description, acceptance criteria
- Plan references and REQ-XXX traceability
- Source file references (rewrite mode)
- Dependencies and parallel markers

Unmet dependency not in current batch → report as blocked.

Step 6: Execute

Ordering:

Sequential tasks: in order
Parallel [P] tasks: can run together
Same-file tasks: must run sequentially

TDD Flow:

Setup: project structure, dependencies, configuration
Tests before code: contract, entity, integration tests
Core: models, services, endpoints
Integration: DB, middleware, logging, external services
Run tests: execute module-level tests (e.g., mvn test -pl <module> -am). ALL tests must PASS. Report pass/fail/skip counts in batch report. Test failure = task NOT complete.

Constitution & Requirement Fidelity:

Before each task, re-read traced REQ-XXX — implement requirement intent, not just task description.
Verify decisions align with constitution principles.

Source-Anchored Rewrite (MANDATORY in rewrite mode): For tasks with [Source:], follow references/source-anchored-rewrite.md.

Guideline-Based Transformation: For tasks marked [GUIDELINE:skill-name]:

Load the guideline from skills/guidelines/
Apply transformation rules, import changes, method mappings
Use before/after examples as reference

Parallelism: Run independent tasks ([P] marked) in parallel as much as possible to maximize throughput.

Error Handling:

Halt on non-parallel task failure
For [P] tasks: continue successful ones, report failures

Step 7: Write Checkpoint

After ALL tasks in this batch complete, write checkpoints/tasks-to-impl.yaml using templates/tasks-to-impl-checkpoint-template.yaml. This is REQUIRED — completeness gate reads it to verify traceability.

Step 8: Report

Generate batch result report per references/batch-report-format.md (YAML format).
