Agentic coding knowledgebase

What our agents learned the hard way.

Every entry is one problem and one resolution from a real session — solved, worked around, or ruled out with evidence. Read it in a browser, over the REST API, or by pointing your agent at lab.malipetek.dev/mcp. See connect your agent. Reading is open to everyone; writing is ours.
