FAQ

Questions

CC Agent Brain

English | 中文

A local-first memory engine for coding agents. It captures what you and the agent actually do, distills it into versioned long-term memory, and recalls it automatically — fully offline, with zero third-party dependencies, and exposed to any tool through MCP. Installs as a namespaced add-on and never replaces your existing .claude/ directory.

English

What is CC Agent Brain

CC Agent Brain turns a stateless coding agent into one that remembers you across sessions and across tools — all locally, no cloud, no API key.

user prompts / assistant replies / tool actions
        ↓ automatic hooks
append-only event stream (SQLite + FTS5)  +  readable Wiki (Markdown)
        ↓ distill
versioned long-term memory (layered, bi-temporal, auditable)
        ↓ BM25 + RRF retrieval, project DB first / global DB fallback
automatic recall in future sessions
        ↓ MCP server
the same memory in Claude Code, Cursor, Codex, Gemini CLI, Claude Desktop…

Why it exists (2026 memory landscape)

Agent memory is becoming standard infrastructure, but existing choices force a trade-off: cloud memory APIs send your data away; heavy self-hosted stacks need vector/graph databases; plain Markdown memory does not actually search or version itself. CC Agent Brain occupies the middle:

Zero-dependency engine — Python stdlib sqlite3 + FTS5 (BM25), including CJK bigram tokenization, so Chinese and English retrieval both work offline.
Real capture loop — user prompts and assistant replies / tool calls are indexed (Stop hook reads the transcript; idempotent).
Versioned, trustworthy memory — facts are superseded/expired, never silently overwritten; a timeline shows what changed and when.
MCP-native, tool-agnostic — one memory store for every MCP client.
Human-readable projection — Markdown Wiki and generated indexes keep you in control; the DB is a single portable file.
Private by construction — common secret shapes are redacted at capture time; personal data is git-ignored.

Quick install

git clone https://github.com/syiibfs-hash/cc-agent-brain.git
cd cc-agent-brain
python installer/install.py --target /path/to/your/project
# preview first:

The engine CLI

BRAIN="python .claude/hooks/cc-agent-brain/brain_store.py"
$BRAIN init
$BRAIN search "deployment decision" --human
$BRAIN memory add --title "..." --body "..." --layer semantic --confidence high
$BRAIN memory add ... --supersedes <old-id>   # replace, keep history
$BRAIN audit / timeline / stats / candidates

Components

6 Hooks

Hook	Event	Purpose
`session_start.py`	SessionStart	onboarding check, engine status
`prompt_capture.py`	UserPromptSubmit	prompt → Wiki projection + event stream
`wiki_context_hint.py`	UserPromptSubmit	real FTS recall for the current prompt
`transcript_capture.py`	Stop	index assistant replies & tool calls
`pre_compact_save.py`	PreCompact	checkpoint before compaction
`memory_audit.py`	Stop	SQL audit: duplicates, broken chains, stale entries

6 Skills — onboarding, wiki update/search, memory distill/audit, material distill. 3 Agents — memory curator, wiki compiler, material distiller.

Memory model

Four layers — working (current task), episodic (timestamped events), semantic (distilled facts/preferences), procedural (reusable workflows). Each memory has status (active/superseded/expired/archived), validity window, confidence, source and supersede chain. See docs/memory-design.md.

Uninstall

python installer/uninstall.py --target /path/to/your/project

Only framework files tracked by the manifest are removed. Your memory/, wiki/, private/ and brain.db are preserved.

Roadmap

Version	Theme	Status
v0.1	Local second-brain MVP (capture/wiki/distill hints)	released
v0.2	Local engine: SQLite+FTS5, full capture, versioned memory, audit, MCP	current
v0.3	Recall quality: optional local embeddings + RRF, built-in recall eval set	planned
v0.4	Portability: Marketplace packaging, one-line install, import/export	planned
v0.5	Optional E2E-encrypted private backup (local-first by default)	planned

Privacy

Open-source framework, no personal data inside. Everything runs on your machine; there is no telemetry and no network call. memory/, wiki/, private/ and *.db are git-ignored. See docs/product-analysis.md for the product rationale.

CC Agent Brain 是什么

给编码 Agent 用的本地记忆引擎：自动捕获你和 Agent 的真实工作过程，蒸馏成带版本的长期记忆，并在后续会话自动召回——全程离线、零第三方依赖，并通过 MCP 把同一份记忆提供给任意工具。以命名空间插件方式安装，绝不覆盖你已有的 .claude/。

用户提示 / 助手回复 / 工具动作
        ↓ 钩子自动捕获
只增事件流（SQLite + FTS5） + 可读 Wiki（Markdown）
        ↓ 蒸馏
带版本的长期记忆（分层、双时间、可审计）
        ↓ BM25 + RRF 检索，项目库优先 / 全局库兜底
后续会话自动召回
        ↓ MCP 服务
同一套记忆服务 Claude Code、Cursor、Codex、Gemini CLI、Claude Desktop…

为什么做它（2026 记忆赛道现状）

Agent 记忆正在成为基础设施，但现有方案都要你做取舍：云记忆 API 要上传数据；重型自建方案要装向量/图数据库；纯 Markdown 记忆既不能真正检索也没有版本。CC Agent Brain 取中间路线：

零依赖引擎：仅用 Python 标准库 sqlite3 + FTS5（BM25），内置中文 bigram 分词，中英文检索全部离线可用。
完整捕获闭环：不只存用户提问，Stop 钩子读取会话记录，把助手回复与工具调用一并索引（幂等）。
可信的版本化记忆：事实变更走"取代/失效"而非静默覆盖，时间线可查"何时因为什么改了结论"。
MCP 原生、不绑工具：一套记忆，所有 MCP 客户端复用。
人类可读投影：Markdown Wiki 与生成式索引让你始终掌控；数据库只是一个可拷贝的文件。
隐私内建：常见密钥形态在捕获时即脱敏，个人数据默认 git 忽略。

快速安装
