Copies the last rendered assistant message to the system clipboard. Reuses the annotate-last session-log lookup (PPID → CWD slug → ancestor walk for Claude Code; CODEX_THREAD_ID for Codex; session dir for Copilot CLI) but skips the UI and writes straight to the clipboard. - Adds cross-platform clipboard helper (pbcopy / clip.exe / wl-copy, xclip, xsel fallback / clip.exe under WSL) - Adds `plannotator copy-last` and `plannotator copilot-copy-last` subcommands - Registers the /plannotator-copy-last slash command in the Claude Code and Copilot plugins plus all three install scripts and their tests
Registers the Pi command that mirrors /plannotator-copy-last in the Claude Code and Copilot CLI plugins. Pi runs on Node, so the clipboard helper was refactored to drop its Bun.file dependency (inline WSL detection via fs.readFileSync) and vendored into apps/pi-extension/ generated/ via vendor.sh — the same reuse pattern used for other shared server utilities. The Pi handler reads the last assistant message from the session manager (same source as /plannotator-last) and writes it to the system clipboard, surfacing success / failure through ctx.ui.notify.

Summary
This PR adds a new
copy-lastcommand that copies the last rendered assistant message to the system clipboard, complementing the existingannotate-lastfunctionality. The command works across Claude Code, Copilot CLI, and other integrations without opening any UI.Key Changes
New clipboard utility (
packages/server/clipboard.ts): Cross-platform clipboard support for macOS (pbcopy), Windows (clip.exe), WSL, and Linux (wl-copy/xclip/xsel)Two new CLI modes in
apps/hook/server/index.ts:copy-last: Copies the last message from standard Plannotator sessions using the same lookup logic asannotate-lastcopilot-copy-last: Copies the last message from Copilot CLI sessionsNew slash commands:
/plannotator-copy-lastfor Claude Code (in both hook and copilot apps)Updated CLI help and tests: Added
copy-lastto the help text and updated test assertions to verify the new command files are installedImplementation Details
copy-lastcommand reuses the existing message lookup infrastructure (getLastRenderedMessage,getLastCodexMessage,getLastCopilotMessage) to find the target messagehttps://claude.ai/code/session_01J3fNDB7ika2PdUdRMdrmHp
