| 3 | //! Command safety analysis for shell execution |
| 4 | //! |
| 5 | //! This module provides pre-execution analysis of shell commands to detect |
| 6 | //! potentially dangerous patterns and prevent accidental damage. |
| 7 | //! |
| 8 | //! ## Command prefix classification |
| 9 | //! |
| 10 | //! [`classify_command`] maps a token slice to its canonical command prefix. |
| 11 | //! The prefix is the portion of the command that identifies *what action* is |
| 12 | //! being taken, stripped of flags and extra positional arguments. |
| 13 | //! |
| 14 | //! The arity dictionary [`COMMAND_ARITY`] encodes, for each known prefix, how |
| 15 | //! many *positional* (non-flag) words after the base command word form the |
| 16 | //! prefix. Flags (tokens that start with `-`) never count toward arity. |
| 17 | //! |
| 18 | //! ### Examples |
| 19 | //! |
| 20 | //! | Input tokens | Arity | Canonical prefix | |
| 21 | //! |---------------------------------------|-------|-------------------| |
| 22 | //! | `["git", "status", "-s"]` | 1 | `"git status"` | |
| 23 | //! | `["git", "checkout", "main"]` | 2 | `"git checkout"` | |
| 24 | //! | `["npm", "run", "dev"]` | 2 | `"npm run"` | |
| 25 | //! | `["docker", "compose", "up"]` | 2 | `"docker compose"`| |
| 26 | //! | `["cargo", "check", "--workspace"]` | 1 | `"cargo check"` | |
| 27 | //! |
| 28 | //! Ported from opencode `packages/opencode/src/permission/arity.ts`. |
