Tighten prompt-mode parity for the Rust CLI by enabling native tools in one-shot runs, defaulting fresh sessions to danger-full-access, and documenting the remaining TS-vs-Rust gaps.
The JSON prompt path now runs through the full conversation loop so tool use and tool results are preserved without streaming terminal noise, while the tool-input accumulator keeps the streaming {} placeholder fix without corrupting legitimate non-stream empty objects.
Constraint: Original TypeScript source was treated as read-only for parity analysis
Constraint: No new dependencies; keep the fix localized to the Rust port
Rejected: Leave JSON prompt mode on a direct non-tool API path | preserved the one-shot parity bug
Rejected: Keep workspace-write as the default permission mode | contradicted requested parity target
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep prompt text and prompt JSON paths on the same tool-capable runtime semantics unless upstream behavior proves they must diverge
Tested: cargo build --release; cargo test
Not-tested: live remote prompt run against LayoffLabs endpoint in this session
This adds an end-to-end OAuth PKCE login/logout path to the Rust CLI,
persists OAuth credentials under the Claude config home, and teaches the
API client to use persisted bearer credentials with refresh support when
env-based API credentials are absent.
Constraint: Reuse existing runtime OAuth primitives and keep browser/callback orchestration in the CLI
Constraint: Preserve auth precedence as API key, then auth-token env, then persisted OAuth credentials
Rejected: Put browser launch and token exchange entirely in runtime | caused boundary creep across shared crates
Rejected: Duplicate credential parsing in CLI and api | increased drift and refresh inconsistency
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep logout non-destructive to unrelated credentials.json fields and do not silently fall back to stale expired tokens
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test
Not-tested: Manual live Anthropic OAuth browser flow against real authorize/token endpoints
