From b9590661d4e0ec4924e1294a2ef756a0f8fccf07 Mon Sep 17 00:00:00 2001 From: Emanuele Fenocchi Date: Wed, 16 Sep 2026 21:52:49 +0000 Subject: [PATCH 1/2] chore(recall): remove the proactive recall hook The UserPromptSubmit hook that auto-searched team summaries and injected a snippet is gone, together with its shared helpers (gate, query, format, events, deadline), its two test files, the esbuild entry, the hooks.json registration and the per-file coverage thresholds. Embeddings default to off, so the gate short-circuited on every prompt for anyone who had not opted in; reactive recall (the agent grepping the memory mount) and capture are untouched. --- esbuild.config.mjs | 1 - harnesses/claude-code/hooks/hooks.json | 5 - src/hooks/recall.ts | 256 ------------ src/hooks/shared/recall-events.ts | 50 --- src/hooks/shared/recall-format.ts | 174 -------- src/hooks/shared/recall-gate.ts | 137 ------- src/hooks/shared/recall-query.ts | 84 ---- src/hooks/shared/with-deadline.ts | 24 -- tests/claude-code/recall-hook.test.ts | 363 ----------------- tests/shared/recall.test.ts | 527 ------------------------- vitest.config.ts | 37 -- 11 files changed, 1658 deletions(-) delete mode 100644 src/hooks/recall.ts delete mode 100644 src/hooks/shared/recall-events.ts delete mode 100644 src/hooks/shared/recall-format.ts delete mode 100644 src/hooks/shared/recall-gate.ts delete mode 100644 src/hooks/shared/recall-query.ts delete mode 100644 src/hooks/shared/with-deadline.ts delete mode 100644 tests/claude-code/recall-hook.test.ts delete mode 100644 tests/shared/recall.test.ts diff --git a/esbuild.config.mjs b/esbuild.config.mjs index 53a00eb1b..d9238c9fa 100644 --- a/esbuild.config.mjs +++ b/esbuild.config.mjs @@ -80,7 +80,6 @@ const ccHooks = [ { entry: "dist/src/hooks/session-start-setup.js", out: "session-start-setup" }, { entry: "dist/src/hooks/session-notifications.js", out: "session-notifications" }, { entry: "dist/src/hooks/capture.js", out: "capture" }, - { entry: "dist/src/hooks/recall.js", out: "recall" }, { entry: "dist/src/hooks/pre-tool-use.js", out: "pre-tool-use" }, { entry: "dist/src/hooks/session-end.js", out: "session-end" }, { entry: "dist/src/hooks/plugin-cache-gc.js", out: "plugin-cache-gc" }, diff --git a/harnesses/claude-code/hooks/hooks.json b/harnesses/claude-code/hooks/hooks.json index e014fe462..9e2c4403e 100644 --- a/harnesses/claude-code/hooks/hooks.json +++ b/harnesses/claude-code/hooks/hooks.json @@ -31,11 +31,6 @@ "command": "node \"${CLAUDE_PLUGIN_ROOT}/bundle/capture.js\"", "timeout": 10, "async": true - }, - { - "type": "command", - "command": "node \"${CLAUDE_PLUGIN_ROOT}/bundle/recall.js\"", - "timeout": 2 } ] } diff --git a/src/hooks/recall.ts b/src/hooks/recall.ts deleted file mode 100644 index e8339ad02..000000000 --- a/src/hooks/recall.ts +++ /dev/null @@ -1,256 +0,0 @@ -#!/usr/bin/env node - -/** - * Proactive Recall — Claude Code UserPromptSubmit hook. - * - * On a *recall-worthy* prompt (cheap gate first — NOT every prompt), search the - * team's summaries and, if the top hit clears a relevance bar, inject ONE - * attributed snippet ("recalled from · ") into the model - * context.
