通过BM25排名进行全文搜索，检索所有过去的Claude Code和Codex会话记录，帮助用户快速回顾和查找历史信息。
npx skills add arjunkmrm/recall --skill recallBefore / After 效果对比
1 组在没有 `recall` 技能时，用户在需要回顾或重用之前 Claude 或 Codex 会话中的信息时，往往需要手动翻阅大量的历史记录，或者在记忆中搜索。这不仅耗时耗力，而且很容易遗漏关键信息，导致重复提问或重新开始。
使用 `recall` 技能后，用户可以通过关键词或短语对所有历史 Claude 和 Codex 会话进行全文搜索。系统能够快速定位到相关的会话片段，帮助用户重用之前的上下文、代码或解决方案，极大地提高了信息检索的效率和工作连续性。

/recall — Search Past Claude & Codex Sessions
Search all past Claude Code and Codex sessions using full-text search with BM25 ranking.
Usage
python3 ~/.claude/skills/recall/scripts/recall.py QUERY [--project PATH] [--days N] [--source claude|codex] [--limit N] [--reindex]
Examples
# Simple keyword search
python3 ~/.claude/skills/recall/scripts/recall.py "bufferStore"
# Phrase search (exact match)
python3 ~/.claude/skills/recall/scripts/recall.py '"ACP protocol"'
# Boolean query
python3 ~/.claude/skills/recall/scripts/recall.py "rust AND async"
# Prefix search
python3 ~/.claude/skills/recall/scripts/recall.py "buffer*"
# Filter by project and recency
python3 ~/.claude/skills/recall/scripts/recall.py "state machine" --project ~/my-project --days 7
# Search only Claude Code sessions
python3 ~/.claude/skills/recall/scripts/recall.py "buffer" --source claude
# Search only Codex sessions
python3 ~/.claude/skills/recall/scripts/recall.py "buffer" --source codex
# Force reindex
python3 ~/.claude/skills/recall/scripts/recall.py --reindex "test"
Query Syntax (FTS5)
-
Words:
bufferStore— matches stemmed variants (e.g., "discussing" matches "discuss") -
Phrases:
"ACP protocol"— exact phrase match -
Boolean:
rust AND async,tauri OR electron,NOT deprecated -
Prefix:
buffer*— matches bufferStore, bufferMap, etc. -
Combined:
"state machine" AND test
After Finding a Match
To resume a session, cd into the project directory and use the appropriate command:
# Claude Code sessions [claude]
cd /path/to/project
claude --resume SESSION_ID
# Codex sessions [codex]
cd /path/to/project
codex resume SESSION_ID
Each result includes a File: path. Use it to read the raw transcript (auto-detects format):
python3 ~/.claude/skills/recall/scripts/read_session.py <File-path-from-result>
If results are missing File: paths, run --reindex to backfill.
Notes
-
Index is stored at
~/.recall.db(SQLite FTS5, auto-migrated from~/.claude/recall.db) -
Indexes both
~/.claude/projects/(Claude Code) and~/.codex/sessions/(Codex) -
First run indexes all sessions (a few seconds); subsequent runs are incremental
-
Only user and assistant messages are indexed (tool calls, thinking blocks, state snapshots skipped)
-
Results show
[claude]or[codex]tags to indicate the source
