dev-recall 0.2.3

Local-first developer memory layer

Recall

Local-first developer memory layer. Captures every developer activity — terminal commands, git commits, file edits, repo opens, AI chat sessions — into a structured SQLite database with a FAISS vector index. Enables natural language recall:

recall ask "what did I work on last Tuesday?"
recall ask "how did I fix the auth bug?"
recall today
recall timeline

---

Quick Start

pip install dev-recall
recall init
source .zshrc  # or .bashrc

recall init will:

1. Create ~/.local/share/recall/ and ~/.config/recall/
2. Initialize the SQLite database + FAISS vector index
3. Install the zsh/bash shell hook (appends source line to your rc file)
4. Set git config --global core.hooksPath to capture all commits
5. Start the background daemon (via systemd user service or subprocess)

---

Commands

Command	Description
recall init	First-time setup
recall ask "<query>"	Natural language search with LLM answer

---

Architecture

Collectors (shell hook, git hooks, VS Code ext, AI log watcher)
    ↓ events (TSV files + HTTP POST)
Daemon (FileWatcher → Enricher → SessionDetector → DB insert → Embedder)
    ↓
Storage (SQLite events.db + FTS5, FAISS vectors.faiss)
    ↓
Query (Hybrid FAISS+FTS5 → RRF → LLM via OpenRouter)
    ↓
CLI + MCP Server

---

Data Sources

Shell commands (zsh / bash)

Add to ~/.zshrc (done automatically by recall init):

source ~/.config/dev-recall/hook.zsh

Git commits

recall init sets core.hooksPath globally — all future commits in any repo are captured.

VS Code activity

Install the extension:

recall vscode install

AI chat sessions

Automatically scanned from:

• GitHub Copilot Chat: ~/.config/Code/User/workspaceStorage/*/GitHub.copilot-chat/debug-logs/
• Claude Code: ~/.claude/projects/*/sessions/
• Aider: .aider.chat.history.md in git repos
• Cursor: ~/.config/Cursor/User/workspaceStorage/

---

LLM Integration

Recall uses OpenRouter for the ask command and daily summaries.

export OPENROUTER_API_KEY=sk-or-...
recall ask "what was I debugging yesterday?"

Without an API key, recall ask falls back to --no-llm mode (shows retrieved events directly). All other commands work fully offline.

---

MCP Server

Use Recall as a context source in Claude Code or VS Code Copilot:

Claude Code (~/.config/claude/mcp.json):

{
  "mcpServers": {
    "dev-recall": {
      "command": "dev-recall",
      "args": ["mcp-serve"]
    }
  }
}

VS Code / Copilot (.vscode/mcp.json):

{
  "servers": {
    "dev-recall": {
      "type": "stdio",
      "command": "dev-recall",
      "args": ["mcp-serve"]
    }
  }
}

Available MCP tools: recall, today_summary, recent_repos, find_command, timeline

---

Privacy

• Commands matching *password*, *secret*, *token* etc. are dropped before storage
• AI chat messages are truncated to 200 characters (intent only, not full content)
• File saves store only path + language, never file content
• All data is local only — LLM calls send only small event snippets, only when you run ask
• Default retention: 90 days (configurable)

recall privacy list           # see what's captured
recall privacy delete --before 2026-01-01
recall privacy ignore --cmd "*mycompany*"

---

Configuration

Config file: ~/.config/dev-recall/config.json

recall config                          # show all settings
recall config daemon_port 8080        # change port
recall config retention_days 30       # shorter retention

Key settings:

{
  "daemon_port": 27182,
  "embedding_model": "all-MiniLM-L6-v2",
  "llm_model": "anthropic/claude-sonnet-4",
  "retention_days": 90,
  "capture": { "terminal": true, "git": true, "vscode": true, "ai_chat": true }
}

Development

git clone <repo>
cd dev-recall
pip install -e ".[dev]"
pytest

Sandbox testing

recall init makes system-wide changes (modifies ~/.zshrc, sets a global git config core.hooksPath, starts a background daemon). Use the provided Docker sandbox to test safely without touching your host environment.

Prerequisites: Docker

# Interactive shell — explore freely
./sandbox.sh

# Run the full test suite
./sandbox.sh test

# Run `recall init` and inspect every file it creates
./sandbox.sh init

# Run any arbitrary command
./sandbox.sh "recall --help"

What the sandbox isolates:

Risk	Mitigation
Modifies ~/.zshrc	Only affects the container's home directory
Sets global git config core.hooksPath	Sandboxed git config, discarded on exit
Starts a background daemon	Killed automatically when the container exits
Network calls to OpenRouter	Blocked via --network none
Privilege escalation	--cap-drop ALL --security-opt no-new-privileges

Alternatively, use a throwaway VM: multipass launch --name dev-recall-test

Roadmap

• v0.1 (current): Shell + git + daemon + CLI ask/today/timeline/stats
• v0.2: VS Code extension + AI chat parsers + week/repos/search/export + auto-summary
• v0.3: MCP server + privacy management + Aider/Cursor parsers
• v1.0: Cross-machine sync + web dashboard + Wakatime-compatible API
