Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install agent-trajectory-learnings

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent reads the sequence of thoughts, tool calls and observations from other agents, extracts successes, failures and false assumptions, then appends them to the learnings file. You get a structured log for later loops.
