| Best For | cap'n hook (capn-hook) is a lightweight, local-first memory tool for coding agents. The problem it solves is simple: agents forget everything when a session ends, so they re-explore the same codebase mysteries every time. capn lets an agent save the files that answer a question the moment it figures them out, then recall them with a single command next session β skipping the rediscovery. The clever part is cache-busting: each saved answer is fingerprinted with the sha256 of its backing files, and the moment a file changes or disappears, that memory is automatically deleted. You never get a stale answer. It installs as a SessionStart hook for Claude Code and Codex (no wrapper, no middleware), stores human-readable Markdown entries in a local, gitignored .capn/ directory, and works agent-agnostically via its CLI. In a benchmark across 60 real developer questions on 5 production codebases, agents using capn recalled answers with 77% fewer tokens than cold exploration at equal correctness. | Leading AI-first code editor and autonomous agent environment with Composer, Cloud Agents, and multi-model intelligence |
