Mistral Vibe Hooks

Part of hooks/ — see also src/hooks/ for installation code

Specifics

• Uses the rtk hook vibe Rust binary (not a shell script) -- no jq dependency
• pre_tool hook declared in ~/.vibe/hooks.toml (user-scoped) with match = "bash" and strict = false
• Reads Vibe's stdin JSON payload (tool_name, tool_input.command, hook_event_name, session_id)
• Returns hook_specific_output.tool_input.command for transparent rewrite plus a system_message for UI visibility
• Non-bash tool / empty command / malformed JSON / RTK-unknown command → passthrough (exit 0, empty stdout)
• RTK permission deny → {"decision":"deny","reason":"..."}
• Alongside the hook, a system prompt at ~/.vibe/prompts/rtk.md is installed as a belt-and-suspenders fallback (skip with --hook-only)
• Installed globally via rtk init -g --agent vibe; there is no project-scoped variant

Notes

• This directory intentionally holds only this README — the hook is a subcommand of the RTK binary (rtk hook vibe), not a standalone script or plugin file, so nothing is deployed here
• Vibe hook contract reference: https://docs.mistral.ai/vibe/code/cli/hooks
