Skill: pipeline-dag-scheduler

Version: 0.1.0

Status: Deprecated

DEPRECATED: This skill has been consolidated into pipeline-toolkit. Use {"operation": "schedule", ...} with the pipeline-toolkit instead.

Trigger

When the agent is asked to implement deterministic pipeline DAG scheduling (Phase 7.0) that composes multiple existing pipelines into a DAG with artifact-only dependencies, resume safety, and fail-closed verification.

Inputs

JSON object:

• dag_spec_path (string, required): Repo-relative path to a DAG spec JSON file.
• runs_root (string, optional): Runs root directory; default "CONTRACTS/_runs".
• project_root (string, optional): Repo root path; default inferred.

Outputs

JSON object:

• ok (boolean)
• code (string)
• details (object)

Side effects:

• Creates or updates deterministic DAG artifacts under <runs_root>/_pipelines/_dags/<dag_id>/ only.
• Does not write artifacts outside allowed roots.

Constraints

• Must be deterministic and idempotent.
• Must not modify CANON or CONTEXT.
• Must not import from CATALYTIC-DPT/LAB/.
• Must fail closed on any schema/validation ambiguity.

Fixtures

• fixtures/basic_ok: a 2-node DAG executes deterministically and is verifiable.
• fixtures/cycle_reject: a cycle is rejected with a stable error code.
