ORCHESTRATOR GATE: If you loaded this skill via the skill() tool, you are the ORCHESTRATOR — STOP. Do NOT execute these instructions inline. Delegate to the dedicated sdd-init sub-agent using your platform's delegation primitive (e.g., task(...), sub-agent invocation, etc.). This skill is for EXECUTORS only.

Executor Override

If you ARE the sdd-init sub-agent (NOT the orchestrator), the gate above does NOT apply to you. Continue with the phase work below. Do NOT delegate. Do NOT call the Skill tool. You are the executor — execute.

Activation Contract

Run this phase when the orchestrator/user asks to initialize SDD in a project. You are the phase executor: do the work yourself, do not delegate, and do not behave like the orchestrator.

Hard Rules

• Detect the real stack, conventions, architecture, testing tools, and persistence mode; never guess.
• In engram mode, do not create openspec/.
• In openspec mode, follow ../_shared/openspec-convention.md and write file artifacts.
• In hybrid mode, write both openspec files and Engram observations.
• Always persist testing capabilities separately as sdd/{project}/testing-capabilities or openspec/config.yaml testing:.
• Always build .atl/skill-registry.md; also save skill-registry to Engram when available.
• Use capture_prompt: false for automated SDD/config saves when supported; omit it if the tool schema lacks it.
• If openspec/ already exists, report what exists and ask before updating it.

Decision Gates

Input	Action
mode=engram	Save context and capabilities to Engram only.
mode=openspec	Create/update openspec bootstrap files only.
mode=hybrid	Do both Engram and openspec persistence.
mode=none	Return detected context only; write no SDD artifacts except registry if required.
strict TDD marker/config found	Use that value.
no marker/config but test runner exists	Default strict_tdd: true.
no test runner	Set strict_tdd: false and explain unavailable.

Execution Steps

1. Inspect project files (package.json, go.mod, pyproject.toml, CI, lint/test config) and summarize stack/conventions.
2. Detect test runner, test layers, coverage, linter, type checker, and formatter.
3. Resolve Strict TDD from agent marker, openspec/config.yaml, detected runner fallback, or no-runner fallback.
4. Initialize persistence for the resolved mode.
5. Build .atl/skill-registry.md using the skill-registry scan rules.
6. Persist testing capabilities and project context.
7. Return the structured initialization envelope.

Output Contract

Return status, executive_summary, artifacts, next_recommended, and risks. Include project, stack, persistence mode, Strict TDD status, testing capability table, saved observation IDs/paths, registry path, and next /sdd-explore or /sdd-new step.
