TokenKnows

Distill AI coding sessions into living knowledge — weekly reports, ADRs, incident reviews, books, agent skills, and a knowledge graph.

What is TokenKnows?

You spend hours pair-programming with Claude Code, Codex, and Cursor. The decisions, bug hunts, and design trade-offs from those sessions evaporate the moment the terminal closes. TokenKnows captures them automatically and distills them into structured, evidence-linked knowledge assets:

capture (6 collectors) → distill (5-stage LLM pipeline) → assets (7 document types) → review / redact / publish

• 📡 Captures everything — Claude Code, Codex, Cursor, VS Code, GitHub PRs/commits/issues, and local docs, all via local file watchers and API polling. No webhooks, no tunnels.
• 📝 Seven asset types — weekly reports, tech designs, ADRs, incident reviews, long-form books, reusable agent skills (SKILL.md), and an entity knowledge graph.
• 🔗 Evidence-linked — every paragraph traces back to the original PR / conversation / commit, ranked by cosine × trust × recency across ≥2 sources.
• 🔒 Local-first, zero egress by default — a three-layer LLM egress gate (instance ∧ project ∧ task) with full audit logging. Pair it with Ollama and run the whole pipeline with zero cloud keys.

Install the plugin

Prerequisite: the TokenKnows backend at http://localhost:8001 and the web UI at http://localhost:5173 (see Quick start), plus uv (the plugin pulls the MCP server from PyPI via uvx). All plugin env vars have working local defaults — export TOKENKNOWS_API_BASE / TOKENKNOWS_API_TOKEN / TOKENKNOWS_DEFAULT_PROJECT / TOKENKNOWS_WEB_BASE only for non-default setups. Register/login in the web UI and create an API token under Project Settings → MCP 接入 when your backend requires auth.

Platform	How
Claude Code	/plugin marketplace add johnnywuj81/tokenknows → /plugin install tokenknows@tokenknows — full walkthrough in tokenknows-plugin/README.md (5-minute quickstart)
Codex	codex plugin marketplace add johnnywuj81/tokenknows → codex plugin add tokenknows@tokenknows (loads skills, commands and the MCP server; local-clone alternative in codex-plugin/README.md)
Cursor	Add the tokenknows MCP block to ~/.cursor/mcp.json (uvx config example in code/tokenknows-mcp/README.md)
VS Code	Download the .vsix from Releases → code --install-extension tokenknows-vscode-*.vsix

The plugin gives your AI tool MCP tools (submit_session_events, distill_document, list_assets, get_asset, get_asset_chapters, search_entity) plus slash commands like /tokenknows:weekly and /tokenknows:adr.

Quick start

# 1. (Optional but recommended) Ollama — fully local inference, zero cloud keys
ollama serve &
ollama pull minimax-m2:cloud          # or gpt-oss:20b, qwen2.5, ...

# 2. Backend (FastAPI + SQLite persistence + 3-layer LLM egress gate)
cd code/tokenknows-api
python3 -m venv .venv && .venv/bin/pip install -e ".[dev]"
cp .env.local.example .env.local      # defaults to Ollama; edit to add cloud providers
.venv/bin/uvicorn app.main:app --host 127.0.0.1 --port 8001

# 3. Frontend (React 19 + Vite)
cd code/tokenknows-web
npm install
npm run dev
# open http://localhost:5173 — talks to the real backend (mocks are opt-in via ?msw=1)

# (Optional) seed demo data
./engineering_handoff/demo-seed.sh

Platform support: macOS — full experience (collectors auto-start via launchd). Linux — backend, frontend, and collectors all run manually (python3 plugins/<x>/sync.py --watch); the launchd scripts don't apply. Windows — untested; WSL2 recommended.

Data collectors

All local — no ngrok, no public webhooks. On macOS they restart on crash and on reboot (launchd).

Collector	Source	Mode
claude-code	~/.claude/projects/*.jsonl	30s polling, incremental offsets
codex	~/.codex/sessions/**/rollout-*.jsonl	30s polling, incremental offsets
cursor	Cursor's state.vscdb (read-only SQLite)	60s polling
github	GitHub REST API · PRs / issues / commits	5min polling (gh auth token)
vscode	VS Code extension onDidSaveTextDocument	buffered, 10s flush
local-docs	~/Documents .md .txt .pdf (watchdog)	realtime, 2s debounce

./scripts/launchd/install.sh          # macOS: install all 5 Python collectors as LaunchAgents
launchctl list | grep com.tokenknows
tail -f ~/Library/Logs/tokenknows/*.log

Every event carries a trust score (0.6 × source_authority + 0.4 × extraction_confidence); the evidence stage ranks citations by 0.6 × cosine + 0.25 × trust + 0.15 × recency and enforces ≥2 distinct sources.

Architecture

Collectors feed an event store (SQLite). A five-stage pipeline (collect → outline → content → evidence → assess) turns events into assets. The LLM Gateway unifies four providers (Anthropic / OpenAI / MiniMax / Ollama) with per-task routing and fallback chains — and refuses any cloud call unless all three egress switches are on.

CI

Workflow	Runner	Trigger
ci.yml	ubuntu-latest (GitHub-hosted)	push to main + every PR
ci-macos.yml	self-hosted macOS ARM64	maintainer pushes to main only — never runs external PR code

Privacy & local-first

• Zero egress by default — cloud LLM calls require the instance and project and task switches all on
• Bring your own keys; the audit log never leaves your machine
• One-click kill switch drops the instance into fully-offline mode

Details: PRD §6.7 data residency & egress control (Chinese).

Most in-depth docs are in Chinese (the project's working language). Code comments are predominantly Chinese too; issues and PRs in English or Chinese are both welcome.
