What a hook decides to do.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Continue

Continue normally.

Halt

Halt the turn (observer tripwire). The turn exits with ExitReason::ObserverHalt.

Fields

reason: String

Reason for halting.

SkipTool

Skip this tool call (only valid at PreToolUse). The tool is not executed and a synthetic “skipped by policy” result is backfilled.

Fields

reason: String

Reason for skipping.

ModifyToolInput

Modify the tool input before execution (only at PreToolUse). Used for: parameter sanitization, injection of defaults.

Fields

new_input: Value

The replacement tool input.

ModifyToolOutput

Replace the tool output with a modified version (e.g., redacted secrets). Only valid at PostToolUse. v0 scope: PostToolUse only. Future: PostInference for redacting final assistant text before return/logging.

Fields

new_output: Value

The replacement output.
