 - Write Grok Build integrations to a native user hook file under non-empty `GROK_HOME` or `~/.grok`; keep Claude Code and Cursor compatibility sources read-only.
 - Write Auggie hooks only to `~/.augment/settings.json`; keep system and workspace settings read-only. Generate `.cmd` wrappers on Windows and `.sh` wrappers on Unix because Auggie dispatches supported script paths, and express hook timeouts in milliseconds.
 - Validate Auggie matcher syntax during installation with Node.js `new RegExp`; keep status and uninstall independent from the JavaScript validator so recovery remains available offline.
-- Write Cline file hooks to `$CLINE_DIR/hooks` with `~/.cline/hooks` as the default; keep Documents and workspace hook roots read-only. Use supported event filenames, preserve official hook input byte-for-byte, and resolve Python runtimes from absolute shebangs. Translate guard exit code `2` into JSON stdout with `cancel: true`. Treat hook errors, timeouts, and invalid control JSON as fail-open.

+Cline installation writes `PreToolUse.mjs` and `PostToolUse.mjs` to `$CLINE_DIR/hooks` (default `~/.cline/hooks`). Elydora leaves the Documents and workspace hook roots unchanged. The wrappers preserve Cline's official payload and translate a frozen guard into JSON stdout cancellation control.

 Kiro CLI installation covers both runtime contracts. Kiro CLI v2 uses the generated custom agent through `kiro-cli --agent elydora-audit`. Kiro CLI v3 loads the global standalone hooks when started with `kiro-cli --v3`.
