Crosslink

The missing memory layer for AI-assisted development.

AI coding assistants forget everything between conversations. Crosslink gives them persistent memory — sessions, handoff notes, issue tracking, and breadcrumbs that survive context compression and session restarts.

Why Crosslink?

Every time an AI assistant's context window fills up or you start a new conversation, the AI loses all context about what it was doing, what's done, and what's next. You end up repeating yourself, re-explaining decisions, and watching the AI redo work.

Crosslink solves this with a local-first issue tracker designed specifically for AI workflows: sessions with handoff notes, breadcrumb tracking that survives context compression, and multi-agent coordination for parallel AI work.

Quick Start

# Install
cargo install crosslink

# Initialize in any project
crosslink init

# Start a session — see what the last AI left you
crosslink session start

# Create + label + start working in one step
crosslink quick "Fix auth token refresh" -p high -l bug

# Record breadcrumbs (survives context compression)
crosslink session action "Found root cause in refresh_token()"

# End with handoff notes for the next session
crosslink session end --notes "Fixed token refresh. Dark mode is next."

Features

• Session memory — Handoff notes, breadcrumbs, and session state survive restarts
• Local-first — All data in SQLite (.crosslink/issues.db), no cloud, works offline
• Smart workflow — quick command, next recommendations, tree visualization
• Behavioral hooks — Claude Code hooks enforce no-stubs, proper error handling, issue tracking
• Multi-agent — Distributed issue locking via git for parallel AI work
• Templates — Built-in templates for bugs, features, refactors, and research
• Subissues & dependencies — Break tasks down, track blocking relationships
• Knowledge pages — Shared documentation synced across agents via the coordination branch
• House style — Sync project rules and policies from a central git repo
• Time tracking, milestones, archiving — Full project management in the CLI
• Works everywhere — CLI + VS Code extension + context provider for any AI agent
