Trait Implementations

impl Target for DroidTarget

fn name(&self) -> &'static str

fn display_name(&self) -> &'static str

fn shell_tool_name(&self) -> &'static str

The harness’s SHELL tool — the only tool this hook should decide about. Droid’s is Execute, Gemini’s run_shell_command; most are Bash. Defaults to Bash, the common case.

fn detect_paths(&self, home: &Path) -> Vec<PathBuf>

fn install(&self, home: &Path) -> Result<InstallOutcome, String>

fn hook_format(&self) -> Option<&dyn HookFormat>

fn hook_format_for(&self, _stdin: &str) -> Option<&dyn HookFormat>

The format that answers THIS envelope. Most harnesses send one hook event, so it is hook_format. Codex sends PreToolUse and PermissionRequest to the same command and expects a different answer to each, so it picks by the event the envelope names.

fn hook_formats(&self) -> Vec<&dyn HookFormat>

Every format hook_format_for can return, so the contract guards that need no envelope walk all of them and a second event’s format cannot ship unchecked. The foreign-tool guard is driven by sample_envelope and reaches only the format that envelope routes to; Codex’s PermissionRequest tool filter has its own test in codex.rs.
