What it does
Reference-coding with XERJ. Clone the libraries that already solved your problem, index them locally, and retrieve the exact implementation before writing code, so the agent reads passages instead of re-deriving algorithms across retry loops. Use when starting a task in an unfamiliar API, porting an algorithm, or when you have already looped twice on the same error.
XERJ.code, reference coding
An agent that does not know an API guesses, runs, fails, and guesses again. Each lap costs output tokens, which are the expensive kind. This skill replaces laps with a lookup: clone the repositories that already contain a correct implementation, index them with XERJ, and retrieve the passage before writing.
The trade is deliberate. Retrieval spends input tokens, which are cheaper per
token and cacheable; loops spend output tokens. See COSTS.md for
the arithmetic and for the conditions under which this trade loses.
