From 6cb1ce100c76edb9d4b3303ca775c5cf6e9e5f45 Mon Sep 17 00:00:00 2001 From: oratis Date: Thu, 28 May 2026 13:30:21 +0800 Subject: [PATCH] =?UTF-8?q?feat(core,cli):=20M5.2=20=E2=80=94=20plugin=20l?= =?UTF-8?q?ive=20wire-up=20(discover=20=E2=86=92=20spawn=20=E2=86=92=20reg?= =?UTF-8?q?ister)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the "M5.1: 65% — needs live registry wireup" line item. Core (@deepcode/core): · packages/core/src/plugins/wireup.ts (NEW, ~140 lines) - wirePlugins({ home, hooks, capabilities, disabled }) — orchestrates discoverPlugins → spawnAllPlugins → mergeHooks(declared) for each successfully started plugin. - WireResult exposes plugins (with contributed hook events), hash mismatches, spawn failures, and a shutdown() to kill subprocesses. - hasInstalledPlugins() probe helper. · packages/core/src/hooks/dispatcher.ts - HookDispatcher.mergeHooks(extra: Hooks) — appends matchers under each event so plugins can extend dispatch at runtime. - `hooks` field changed from readonly to private mutable. · packages/core/src/plugins/runtime/subprocess.ts - Exposes `get plugin()` and `get isAlive()` accessors so wireup can map subprocess back to its source InstalledPlugin without reaching into private opts. · packages/core/src/agent.ts - ToolContext.sessionDir is now derived from `${sessions.root}/${sessionId}` so TodoWrite persists to the session-scoped dir and /todos can read it back. CLI (deepcode-cli): · apps/cli/src/repl.ts + headless.ts - Both bootstraps now call wirePlugins() after HookDispatcher construction, build a capability bridge from BashTool/ReadTool/WriteTool/ WebFetchTool, and shutdown() the wire on exit. - SessionContext carries wiredPlugins + pluginWarnings so /plugins can render them. · apps/cli/src/commands.ts - NEW /plugins slash command. Lists active plugins with their version and contributed hook events; surfaces hash drift + spawn failure warnings. - /todos rewritten — now actually reads `//todos.json` via readTodos() helper. Tests: core 308 → 317 (+9 wireup tests); cli 43 → 47 (+4 /plugins+/todos); total 360 → 364 passing. (`pnpm -r test`). BEHAVIOR_PARITY: /todos and /plugins move from 🔄 to ✅.
