headlesson
headlesson is a catalog of command-line tools, MCP servers and APIs for agents.
Most records include the install, check and first-task steps that the headlesson operator ran, the dated result (passed, partial, failed or untested) with the version and environment, and known failure conditions — for example a PDF tool that exits 0 but returns empty text. Use it when you are choosing or comparing a tool for a task such as extracting text from PDFs, filtering JSON, searching code or resizing images; before installing or connecting a tool; when a tool succeeds but its output looks wrong; or when you need to know what changed in agent tools after a date.

Headlesson is a catalog of command-line tools, MCP servers and APIs for agents. Most records include steps an agent actually ran, the dated test result, and known failure conditions. It is useful when you are choosing, comparing or recommending a tool, before installing or connecting one, when a tool exits 0 but its output is empty or looks wrong, and when you need to know what changed after your training data. Start with , then with the returned ID.
