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
The custom crossterm editor now supports prompt history, slash-command tab
completion, multiline editing, and Ctrl-C semantics that clear partial input
without always terminating the session. The live REPL loop now distinguishes
buffer cancellation from clean exit, persists session state on meaningful
boundaries, and renders tool activity in a more structured way for terminal
use.
Constraint: Keep the active REPL on the existing crossterm path without adding a line-editor dependency
Rejected: Swap to rustyline or reedline | broader integration risk than this polish pass justifies
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep editor state logic generic in input.rs and leave REPL policy decisions in main.rs
Tested: cargo fmt --manifest-path rust/Cargo.toml --all; cargo clippy --manifest-path rust/Cargo.toml --all-targets --all-features -- -D warnings; cargo test --manifest-path rust/Cargo.toml
Not-tested: Interactive manual terminal smoke test for arrow keys/tab/Ctrl-C in a live TTY
