Execute Ideation Specification

Arguments: $ARGUMENTS

Execute a spec file generated by the ideation skill.

Flags:

• --parallel — dispatch subagents for independent components.
• --headless — auto-proceed through every confirmation (no AskUserQuestion). Used by /ideation:autopilot.
• --strict — modifies --headless to fail closed where plain headless fails open. Set by autopilot for express-approved contracts (approvalMode: "express" in contract-data.json), whose artifacts no human reviewed — the fail-open defaults are calibrated for reviewed artifacts.
• Remaining argument: spec file path (optional).

Example: /ideation:execute-spec --parallel or /ideation:execute-spec --headless docs/ideation/foo/spec-phase-1.md

Headless/strict gate semantics — owned by workflows/README.md's gate-behavior table; when prose and engine disagree, the tests are right. Do not restate the matrix here — the original defect (strict specified to fail closed, actually improvising) shipped exactly because divergent prose copies drifted from the engine.
