## sdd-init

output: init.md
outputMode: file-only
progress: true

Initialize SDD context for {task} before any planning or implementation. If `openspec/config.yaml` is missing, inspect the project and create it automatically. If it already exists, read it, refresh only safe derived context when appropriate, and report the current SDD/testing configuration without blocking the chain.

## sdd-explore

reads: init.md
output: exploration.md
outputMode: file-only
progress: true

Explore {task}. Identify scope, risks, dependencies, prior art, and whether the change should proceed into proposal.

## sdd-proposal

reads: exploration.md
output: proposal.md
outputMode: file-only
progress: true

Create or update the OpenSpec proposal for {task} using the exploration notes and the previous step output.

## sdd-spec

reads: proposal.md
output: spec.md
outputMode: file-only
progress: true

Write delta specs for {task} from the approved proposal. Preserve RFC 2119 requirements and Given/When/Then scenarios.

## sdd-design

reads: proposal.md+spec.md
output: design.md
outputMode: file-only
progress: true

Design the technical approach for {task} using the proposal, specs, and previous outputs. Call out review and judgment risks.

## sdd-tasks

reads: proposal.md+spec.md+design.md
output: tasks.md
outputMode: file-only
progress: true

Create strict-TDD, reviewable implementation tasks for {task}. Include the required Review Workload Forecast guard lines and PR split recommendation.

## sdd-apply

reads: proposal.md+spec.md+design.md+tasks.md
output: apply-progress.md
outputMode: file-only
progress: true

Implement only approved tasks for {task}; enforce strict TDD when active and stop before writing if workload decisions are unresolved. Update OpenSpec tasks and apply-progress with evidence.

## sdd-verify

reads: proposal.md+spec.md+design.md+tasks.md+apply-progress.md
output: verify-report.md
outputMode: file-only
progress: true

Verify {task} against specs, design, tasks, implementation, apply-progress, strict TDD evidence, assertion quality, and review workload boundaries.

## sdd-sync

reads: proposal.md+spec.md+design.md+tasks.md+apply-progress.md+verify-report.md
output: sync-report.md
outputMode: file-only
progress: true

Sync verified file-backed delta specs for {task} into `openspec/specs/` without archiving. In Engram-only mode, report that canonical sync is not applicable.

## sdd-archive

reads: verify-report.md+sync-report.md
output: archive-report.md
outputMode: file-only
progress: true

Archive {task} only when the verification report passes and file-backed sync is complete or not applicable; otherwise report that archive is blocked and preserve active artifacts.
