Chain figure-out --autonomous (when the transcript lacks shared understanding) → define --autonomous → do on a single task. The --autonomous flag on figure-out makes the model self-answer with recommended answers instead of waiting on the user (see figure-out/references/autonomous.md). Surface define's Summary for Approval for visibility, then treat it as approved and proceed to /do.
Task text comes from $ARGUMENTS; if empty, infer from conversation context (summarize the discussed task into a concrete description). Fresh session with no context and no args → halt: No task description provided and no conversation context to infer from. Usage: /auto <task description> | /auto --babysit <pr-url>.
Verification policy. Parse only top-level option uses of --verification and --verifier-model as /auto flags; quoted or topic mentions remain task text. Omitted --verification means per-gate. After resolving that default, load the matching sibling /do reference under ../do/references/ and apply its policy validation before /define; the reference, not /auto, owns mode-specific model support and evidence provenance. Remove parsed flags from the task before /define, and forward them only to /do. Never write either option into the Manifest. Use the reference's required evidence/provenance wording when recording each gate's provenance in the ledger.
Babysit mode (--babysit <pr-url>) skips fresh synthesis. Invoke define with --babysit <pr-url> --autonomous, then /do with the parsed verification options. PR-lifecycle platform auto-detects from PR URL host (github.com → github composition); non-github host → halt. Multi-repo manifest produced by /define → single /do invocation navigates all repos.
Failure handling. /define returns no manifest path → stop, report. /do invokes terminal escalation after useful independent work is exhausted → surface the escalation verbatim to the user with the intervention it names. An earlier blocker notice is progress, not a terminal result.
Continuation. Do not set or print a continuation goal during understanding or definition. When invoking figure-out, keep its full Read bar as the checkpoint before define, without a phase goal. Pass the exact Manifest path define reports to /do; /do owns the completion backstop, including native goal-setting and the manual completion contract. No path → stop and report. Automatic continuation begins at execution; an interrupted earlier phase must be restarted by the caller.
