release/v1.5.10
release/v1.5.6
release/v1.6.1
| 1 | //! Tool permission policy: which agent tools may run, and when to ask. |
| 2 | //! |
| 3 | //! Every tool call funnels through one decision point before execution |
| 4 | //! (`decision_for`). Tools are classified by risk: *read-only* tools (reading |
| 5 | //! files, searching, listing, fetching a web page) always run, while *mutating* |
| 6 | //! tools (writing files, deleting, shell commands, MCP tools) are governed by |
| 7 | //! policy. The policy layers, first match wins: |
| 8 | //! |
| 9 | //! 1. **Plan mode** — a per-session switch that denies every mutating tool with |
| 10 | //! a message telling the model to present a plan instead. Toggled via |
| 11 | //! `/plan on|off` (TUI and ACP) or the panel Permissions dropdown. |
| 12 | //! 2. **Session grants** — "always allow this session", recorded when the user |
| 13 | //! picks that option in an approval prompt. For `run_command` the grant is |
| 14 | //! scoped to the command's first two whitespace-separated tokens (approving |
| 15 | //! `git push origin main` records `run_command(git push)`); other tools |
| 16 | //! record the bare tool name. "Always deny this session" records a rule |
| 17 | //! scoped the same way, and a session denial is checked before a session |
| 18 | //! grant. |
| 19 | //! 3. **Rule lists** — `[permissions.rules]` in `settings.toml`: ordered |
| 20 | //! `deny` and `allow` lists of rules shaped `tool_name` or |
| 21 | //! `tool_name(argument_pattern)`, e.g. `run_command(git status)`, |
| 22 | //! `run_command(cargo *)`, `edit_file(src/*)`. The pattern matches the |
| 23 | //! command string for `run_command` and the path argument for the |
| 24 | //! file-mutating tools; for tools with no obvious argument (MCP tools, |
| 25 | //! unknown tools) only a bare `tool_name` rule matches. `deny` is checked |
| 26 | //! before `allow`, so a deny always beats an allow matching the same call. |
| 27 | //! 4. **Per-tool override** — `[permissions.tools]` in `settings.toml`, e.g. |
| 28 | //! `run_command = "ask"`, `edit_file = "allow"`, `delete_file = "deny"`. |
| 29 | //! 5. **Session mode (panel dropdown), else the stored default** — the ACP |
| 30 | //! panel's Permissions selector (`Manual`/`Auto`) picks a |
| 31 | //! [`settings::PermissionMode`] for the session, stored beside `plan_mode`; |
| 32 | //! with no session override, `[permissions] default = "ask"|"allow"|"deny"` |
| 33 | //! in `settings.toml` applies (`ask` on a fresh install). |
| 34 | //! |
| 35 | //! Pattern matching (rules and session grants share it): `*` is a glob-style |
| 36 | //! wildcard (the `glob` tool's translator). A pattern ending in `*` matches |
| 37 | //! everything from the wildcard on — `run_command(cargo *)` covers |
| 38 | //! `cargo build src/main.rs`. A pattern without a trailing `*` must be the |
| 39 | //! whole argument or end at a whitespace boundary: `run_command(git status)` |
| 40 | //! matches `git status` and `git status --short` but not `git status-x`. |
| 41 | //! |
| 42 | //! The `SIGIT_PERMISSIONS` env var (`allow`/`ask`/`deny`) overrides the stored |
| 43 | //! default without writing the file — the escape hatch for ACP clients that |
| 44 | //! cannot answer `session/request_permission` and for CI/headless runs. |
| 45 | //! |
| 46 | //! Tools discovered from MCP servers (`mcp__*`) and any unknown tool name are |
| 47 | //! treated as mutating: external tools can have arbitrary side effects, so the |
| 48 | //! safe assumption is to gate them. The exceptions are the query tools of the |
| 49 | //! two baked-in servers — the official sigit.si server and the smbCloud CLI — |
| 50 | //! which are read-only (see [`classify`]). |
| 51 | //! |
| 52 | //! Session state (grants + plan mode) lives in a process-global keyed by |
| 53 | //! session id — the same pattern as `mcp.rs`'s server cache — so the ACP |
| 54 | //! multi-session surface and the single-session TUI share one implementation. |
