name: graph-sanity description: Runs deterministic sanity checks against the decision graph to ensure outputs conform to MVP rules and DecisionDTO schema.

Graph Sanity Skill

Purpose

Ensures the decision graph produces valid, deterministic DecisionDTO outputs for a set of predefined command fixtures.

Inputs

• Command fixtures in .codex/skills/graph-sanity/fixtures/commands/.
• Decision graph implementation in graphs/core_graph.py.
• Decision JSON Schema in contracts/schemas/decision.schema.json.

Outputs

• Validation report printed to stdout.
• Non-zero exit code on any schema or rule violation.

Checks

• Output DecisionDTO conforms to schema.
• action is limited to MVP enum.
• schema_version matches contracts/VERSION.
• Deterministic decision_version.

Definition of Done (DoD)

• All fixtures pass validation.
• No unexpected actions or payload shapes.
• Script exits with status 0.
