+# Agent permissions (Build mode)
+
+MoCode separates **who enforces permissions** from **who invokes shell commands**, aligned with Claude Code harness behavior.
+
+## CLI TUI is the permission gate
+
+Dangerous bash commands are blocked by a **blocklist** in the CLI (`packages/cli/src/lib/bash-approval.ts`, via `requiresApproval()` called from `use-chat.ts`), not by the model asking in chat. When a command matches the blocklist:
+
+1. Execution pauses before the command runs.
+2. A TUI modal appears: **Approve once** / **Reject** / **Allow for this session**.
+3. Keyboard navigation: **↑ / ↓** to move, **Enter** to confirm, **Esc** to reject.
+
+Non-blocklisted commands (e.g. `npm test`, `git status`) run immediately with no dialog.
+
+## Model behavior
+
+In Build mode the model should:
+
+- **Invoke bash directly** for shell work — do not ask in chat whether to run a command first.
+- Treat the **TUI approval dialog as the sole confirmation** for dangerous commands; chat messages are not a permission gate.
+- **Not retry** a rejected command unless the user explicitly asks again. On rejection, acknowledge and suggest alternatives.
+- Use the optional **`description`** field on bash tool calls when the command string alone does not convey intent (shown as a dim line in the transcript).
+
+## Plan mode
+
+Plan mode has no bash tool. Git inspection uses read-only `gitStatus` and `gitDiff` tools instead.
