📝 Walkthrough

Walkthrough

Direct terminal attach preserves complete bracketed pastes as opaque UTF-8 payloads. Prefix bindings support layout-aware generated characters with exact-key precedence. Claude detectors recognize background MCP task activity. The documentation adds macOS Keychain troubleshooting guidance.

Changes

Bracketed Paste Handling

Layer / File(s) Summary
Parse and forward bracketed pastes
src/raw_input.rs, src/client/mod.rs
The parser validates complete bracketed paste sequences. Direct attach forwards paste data without interpreting prefix-like bytes and sends pending prefixes separately.
Route paste input through terminal attach
src/server/headless.rs
The server sends plain paste text when bracketed paste mode is disabled and preserves delimiters when it is enabled. Tests cover both runtime paths.
Validate terminal setup and restoration
src/client/mod.rs, tests/client_mode.rs, docs/next/CHANGELOG.md
Direct attach enables bracketed paste reporting. Tests verify terminal restoration and post-detach output handling. The changelog records multiline paste preservation.

Prefix Binding Resolution

Layer / File(s) Summary
Resolve layout-aware prefix bindings
src/app/input/navigate.rs
Prefix matching checks exact actions, commands, and indexed actions before retrying with a generated single character. Tests cover precedence and multi-character rejection.

Claude Background Task Detection

Layer / File(s) Summary
Detect background MCP task activity
src/detect/manifests/claude.toml, website/agent-detection/claude.toml
The Claude manifests detect multiline running MCP task summaries and exclude confirmation, cancellation, permission, and answer-editing prompts. Version metadata is updated.

macOS Keychain Troubleshooting

Layer / File(s) Summary
Document launch-context diagnosis
docs/next/website/src/content/docs/troubleshooting.mdx, docs/next/website/src/content/docs/ja/troubleshooting.mdx, docs/next/website/src/content/docs/zh-cn/troubleshooting.mdx
The troubleshooting pages explain launch-context checks, GUI-terminal restart steps, and background or SSH limitations for interactive Keychain access.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 81864

The troubleshooting instructions should clearly direct users to run the restart commands from a separate GUI terminal, since using the affected pane can terminate its processes. This is a bounded documentation risk requiring owner awareness before merge.

Poem

A rabbit guards each paste in line,
Exact keys keep their place and shine.
MCP tasks glow while Claude works,
Clean signals hop past hidden quirks.
The terminal rests, restored and bright.

Add regression tests for the new matcher.

Test a wrapped MCP summary that must produce working. Test each excluded prompt and the intended wrapping boundary. Add these cases to the existing manifest test suite in src/detect/manifest/tests.rs.

Superseded by #22.

This PR's head branch is herdrdev:master, so conflict resolutions can't be pushed to it — the merge had to happen on a branch in this fork instead. #22 carries the same 14 upstream commits with all three conflicts resolved and scripts/docker-check.sh green.
