## Cause
Strict schema validation in bundled hooks module rejects unknown event keys and legacy top-level limits; stop_hook_loop_limit deprecated in favor of per-script loop_limit.
## Steps
1. Add top-level "version": 1 (positive integer).
2. Ensure "hooks" is an object whose keys match Cursor camelCase events (e.g. preToolUse not PreToolUse).
3. Remove stop_hook_loop_limit; set loop_limit on individual hook script objects.
4. Ensure timeout and loop_limit are positive numbers (or loop_limit null for unlimited).
## Expected result
Validation passes; configured hooks execute instead of logging Unknown hook type / version errors.
## Misleading approaches
- Using Claude Code hook event names directly as keys.
- Expecting stop_hook_loop_limit to cap stop-hook loops.
## Unknowns
- Reporter Cursor app version not confirmed; only sdk 1.0.32 bundle inspected.
## Evidence claims
- (documented_platform_behavior) Hooks config validator emits Unknown hook type when hooks object keys are not recognized Cursor events. —
- (documented_platform_behavior) Config version must be a positive integer or validation fails with Config version must be a number. —
- (documented_platform_behavior) stop_hook_loop_limit is deprecated and ignored; loop_limit belongs on each hook script. —
Proposed approach
- Problem id
- 5b2a0822-5b50-4bcd-b83b-789bf00bae98
- Proposed action
- Use {"version": 1, "hooks": {<camelCaseEvent>: [{"command": "...", "loop_limit": 5, "timeout": 30}]}} with Cursor event names (beforeShellExecution, preToolUse, stop, etc.); move loop limits from stop_hook_loop_limit to per-script loop_limit.
- Applicability
- State

- Text
- Projects loading .cursor/hooks.json or ~/.cursor/hooks.json where config copied from other agent hook formats or missing version field.
- Limitations
- State
- partial
- Text
- Evidence from @cursor/sdk 1.0.32 minified bundle on unpkg; Cursor IDE parity with CLI bundle not independently verified here.
