The warning itself follows the judge's `scope` answer (`unrelated` and `plausible side step` warn at any score), and every off-task notice is trace-only: no setting makes it reach the agent (the steer is off on the 2026-09-30 blind labels, see [guards.md](guards.md#steer-calibration-2026-09-30-blind-labels)).

The steer arrives after the call ran. Blind labels on 140 sampled calls put the score's separation of a differing call at AUROC 0.815, but of the 37 steers that would reach the agent, 36 were calls the plan or the user's latest request had asked for.

User-declared rules keep their declared action in both modes. User file only; project files cannot change it. | | `action.commandRules` | User-defined command rules: `{ id, pattern, severity: "warn" \| "confirm" \| "deny", action?, message?, caseSensitive? }`. `block` is the same as `deny`. A missing `severity` is `warn`; any other value is never downgraded: the rule applies at `confirm` and a config warning names the rule, the value, and the valid values. Patterns match the data-text-stripped command, so heredoc bodies and commit messages do not fire them. `confirm` defaults to `action: "dialog"` (a prompt for you, in every mode); `action: "hold"` restores steer semantics. Patterns are JavaScript regexes matched against full commands, so a pattern with nested quantifiers can be slow on long commands — a pathological one is self-inflicted. User rule ids must not reuse a built-in id (see `EXEMPTABLE_IDS` in `src/guard.ts`); a collision silently drops the user rule.

The blind labels found no off-task call in 427 (the 95% upper bound on the off-task rate is below 1%) and only two calls a careful engineer would ask about: merging two pull requests that no instruction named, and reading a third-party API key from a live deployment for a side experiment. On this corpus the categorical `scope` answer and both score bands mostly name calls the visible instructions cover, so the off-task and should-proceed notices stay trace-only: `offTaskTraceOnly` in `src/guard.ts`, and `action.shouldProceed.steer` stays `false`. The thresholds (`action.offTask.warn`, `action.offTask.steer`, `action.shouldProceed.threshold`) decide only the reason text and the trace counts; no setting makes one of these notes reach the agent from a score alone. One labeller produced the labels — a language model, not a person — and a second, human pass would make the numbers stronger. + +One reworded question is proposed for should-proceed, recorded as `extra` only (never acted on): `should_ask` in `scripts/action-candidates.mjs` asks whether any visible instruction covers the call, where `should_proceed` names every commit, push, merge or deploy as a decision the user should make. That difference matters here: the shipped wording puts 32% of judged calls at or below 0.6 while 2 of 427 labelled calls needed asking. `scripts/steer-ask-probe.mjs` measures the rewording on these same labels, one request per call, next to the shipped question. The measurement cannot run at the moment of writing: the TypeSafe account answers HTTP 402 (no balance).
