Module exit_mode 

Library-level support for --exit interactive mode.

When a session is launched with --exit [<hint>], the user prompt is augmented with instructions telling the agent to call zag ps kill self <result> (or zag ps kill self --file <path>) to terminate the session and submit the final result.

This module owns the prompt template, the typed ExitHint / ExitConstraints state, and the validation logic used by zag ps kill to accept or reject a submitted result.

Structs

ExitConstraints

All exit-mode constraints captured at session launch.

Enums

ExitHint

State of the --exit flag for a single session.

ExitValidationError

Reason a zag ps kill invocation was rejected. The CLI prints the Display impl to stderr; the agent is expected to read the message and self-correct.

Functions

build_exit_suffix

Build the suffix appended to a user prompt when a session is launched with --exit.

exit_template

Exit prompt template (front matter stripped) — {HINT_SECTION}, {JSON_INSTRUCTION}, {SCHEMA_INSTRUCTION} are replaced at run time.

validate_exit_result

Validate a result string against the constraints recorded on a session at launch time. Returns Ok(()) if the kill should proceed.
