Desktop app that automatically captures your AI coding agent sessions (Claude Code, Cursor, Copilot) as searchable Markdown
Preserve your coding agent trails.
<i>Contrails, short for "condensation trails", are the trails left behind by aircrafts at high altitudes.</i>
Contrails is an opensource app (macOS, Windows and Linux) that:
This way you keep the reasoning that led to fixing a bug or implementing a feature.

Built with Wails v2 (Go + React + TypeScript).
Coding agents forget everything between sessions. The reasoning that led to a fix, the wrong approaches that were tried, the self-corrections — all of it vanishes.
<br/>
Contrails watches agent session files in real-time and outputs clean, human-readable Markdown into a contrails/ directory in your project, making your agent conversations part of your repo history.
When working on a related feature in the future, you can reference relevant contrails to help the agent remember its previous reasoning.

Mine your Claude Code and Codex logs into a local you.md agent profile.
Local-first AI coding agent for VS Code & Cursor. Ollama, LM Studio & your inference fleet. Cursor-grade agent UX — offline, private, zero token cost.
A self-improving skill for AI coding agents (Claude Code, Cursor, AGENTS.md): recognize a hard-won golden path in a session and harvest it into a reusable skill/rule for next time.
Second brain for Forward Deployed Engineers. Engagement memory + 35 skills across 6 domains, all behind one @fde... Works with any AI coding agent.
Game-development Agent Skills for AI coding agents: install once and a master router loads the right skill for your engine and task. 66 original, version-pinned skills (plus a master router) in the portable SKILL.md format that runs across Claude Code, Cursor, Codex, Copilot, Gemini CLI and more, for Godot, Unity, Unreal, web and beyond.
Honey (I Shrunk the AI) by GreenPT: a cross-tool coding skill that cuts AI coding-agent token usage and LLM API costs — write less code, less prose, and denser agent-to-agent handoffs (−53%, lossless in benchmarks) with no loss of quality. Works with Claude Code, Cursor, GitHub Copilot, Codex, Gemini CLI, Windsurf, Cline & Kiro.
