The body is lean and assumes Claude's competence; guidance is direct ('Stop generating immediately', 'Keep offers to one short sentence') with example transcripts that each earn their place rather than padding.

Provides concrete, copy-ready prompts and specific behaviors for each exercise type, plus an explicit 'Pause for input' protocol with exact allowed phrases.

The 'Pause for input' core principle gives an explicit sequenced workflow (stop, wait, then branch on correct/wrong responses) with a clear feedback loop and checkpoint, and the exercise types are well-sequenced.

The body is a concise overview with a clearly signaled, one-level-deep reference to references/PRINCIPLES.md (verified to exist), with content appropriately split and easy navigation.

Lists multiple concrete actions and contexts ('Offers interactive learning exercises after architectural work (new files, schema changes, refactors)') rather than vague language.

Clearly answers both what (deliberate skill development via exercises) and when ('Use when completing features, making design decisions...'), with explicit triggers and exclusions.

Includes natural phrases users would actually say ('learning exercise', 'help me understand', 'teach me', 'why does this work') with good coverage of variations.

Occupies a clear niche (post-work learning exercises) with distinct triggers and an explicit 'Do NOT use for urgent debugging, quick fixes' clause that reduces conflict.
