The active Rust CLI path now keeps users informed during streaming with a waiting spinner,
inline tool call summaries, response token usage, semantic color cues, and an opt-out
switch. The work stays inside the active + renderer path and updates
stale runtime tests that referenced removed permission enums.
Constraint: Must keep changes in the active CLI path rather than refactoring unused app shell
Constraint: Must pass cargo fmt, clippy, and full cargo test without adding dependencies
Rejected: Route the work through | inactive path would expand risk and scope
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep future streaming UX changes wired through renderer color settings so remains end-to-end
Tested: cargo fmt --all; cargo clippy --all-targets --all-features -- -D warnings; cargo test
Not-tested: Interactive manual terminal run against live Anthropic streaming output
The Rust CLI/runtime now models permissions as ordered access levels, derives tool requirements from the shared tool specs, and prompts REPL users before one-off danger-full-access escalations from workspace-write sessions. This also wires explicit --permission-mode parsing and makes /permissions operate on the live session state instead of an implicit env-derived default.
Constraint: Must preserve the existing three user-facing modes read-only, workspace-write, and danger-full-access
Constraint: Must avoid new dependencies and keep enforcement inside the existing runtime/tool plumbing
Rejected: Keep the old Allow/Deny/Prompt policy model | could not represent ordered tool requirements across the CLI surface
Rejected: Continue sourcing live session mode solely from RUSTY_CLAUDE_PERMISSION_MODE | /permissions would not reliably reflect the current session state
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Add required_permission entries for new tools before exposing them to the runtime
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test -q
Not-tested: Manual interactive REPL approval flow in a live Anthropic session
