Add a self-update command to the Rust CLI that checks the latest GitHub release, compares versions, downloads a matching binary plus checksum manifest, verifies SHA-256, and swaps the executable only after validation succeeds. The command reports changelog text from the release body and exits safely when no published release or matching asset exists.\n\nThe workspace verification request also surfaced unrelated stale permission-mode references in runtime tests and a brittle config-count assertion in the CLI tests. Those were updated so the requested fmt/clippy/test pass can complete cleanly in this worktree.\n\nConstraint: GitHub latest release for instructkr/clawd-code currently returns 404, so the updater must degrade safely when no published release exists\nConstraint: Must not replace the current executable before checksum verification succeeds\nRejected: Shell out to an external updater | environment-dependent and does not meet the GitHub API/changelog requirement\nRejected: Add archive extraction support now | no published release assets exist yet to justify broader packaging complexity\nConfidence: medium\nScope-risk: moderate\nReversibility: clean\nDirective: Keep release asset naming and checksum manifest conventions aligned with the eventual GitHub release pipeline before expanding packaging formats\nTested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace --exclude compat-harness; cargo run -q -p claw-cli -- self-update\nNot-tested: Successful live binary replacement against a real published GitHub release asset
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
