Hooks inherit the harness env, so a per-command GSTACK_SESSION_KIND prefix inside a subagent's bash can never reach them. Levers added: a deterministic [conductor][spawned] auto-choose deny for env-level spawned sessions (OPENCLAW_SESSION or session-wide GSTACK_SESSION_KIND), and a spawned escape sentence appended to both hooks' prose directives so a marked subagent that slips and calls AUQ resolves to auto-choose instead of prose-STOP. The sentence lives in one shared constant (hosts/claude/hooks/spawned-directive.ts) so the two paths can never drift; destructive semantics are unified to conservative-continue.

/**
|
|
* Shared spawned-session directive text for the AUQ hooks (#2733).
|
|
*
|
|
* Hook processes inherit the HARNESS env, so a per-command
|
|
* `GSTACK_SESSION_KIND=spawned` prefix inside a subagent's bash call can
|
|
* never reach a hook — the only levers a hook has for the subagent case are
|
|
* (a) env-level markers that ARE session-wide (OPENCLAW_SESSION, or a harness
|
|
* launched with GSTACK_SESSION_KIND in its env) and (b) directive TEXT the
|
|
* model reads. Both AUQ hooks (question-preference PreToolUse deny,
|
|
* auq-error-fallback PostToolUse directive) carry the same escape sentence;
|
|
* it lives here as one constant so the two paths can never drift into
|
|
* contradictory instructions.
|
|
*
|
|
* Destructive semantics are unified across every spawned surface (dispatch
|
|
* prompt, spawned-session block, AUQ prose rule, both hooks):
|
|
* conservative-continue, never prose-STOP — a prose brief with no reader is
|
|
* always wrong in a spawned session, and the conservative choice guarantees
|
|
* nothing irreversible happens.
