Development

Transform session learnings into permanent capabilities (skills, rules, agents). Use when asked to "improve setup", "learn from sessions", "compound learnings", or "what patterns should become skills".

Compare data structures (DuckDB, LanceDB) via ACSets with persistent homology coverage analysis and geometric morphism translation.

Composio OAuth integration for external service connections. CSRF-protected flow with state management, connection lifecycle transitions (pending→initiated→active), dynamic tool building from active connections, token expiration handling. Triggers on "composio", "oauth", "integration", "connection", "external service", "third-party".

vi sshagent.sh ```bash eval $(ssh-agent -s) > /dev/null ssh-add ~/.ssh/id_ed25519 ``` 会自动设置`SSH_AUTH_SOCK`环境变量 1. 打开命令行工具 2. 运行SSH代理 - windows系统：`start-ssh-agent`并输入私钥密码 - 类Unix系统：`ssh-agent $SHELL` 和 `ssh-add 私钥路径` (路径默认值是~/.ssh/id_ed25519)，输入私钥密码(可能暂不能关掉命令行工具才起效，等git操作一次后就可以关掉命令行了) 3. 运行命令`code`来启动VSCode 另外的思路：先启动VSCode，然后在VSCode命令行中运行SSH代理，接着其它操作。 你一般只能在VSCode打开一个项目，如果要打开多个项目就要启动多个VSCode，其实你可以`将多个项目集中到工作区里`方便统一进行管理。
