Conciseness

The body is lean and mostly assumes Claude's competence, with a few explanatory constraint bullets that could be tightened slightly.

Actionability

Provides a concrete output file tree and executable 'tessl eval' commands, but delegates the core how-to guidance to the reference file rather than embedding it.

Workflow Clarity

A clear sequence is present (prerequisites, read reference, produce files, run evals) with a feasibility checkpoint, though detailed validation loops live in the referenced file rather than the body.

Progressive Disclosure

Clear overview body with a single well-signaled one-level-deep reference (references/scenario-generation.md, which exists), with content appropriately split between the two.

Specificity

Lists multiple concrete actions — 'Creates inventory of instructions from the skill, test cases with success criteria, and validates skill coverage' — giving comprehensive coverage of what the skill does.

Completeness

Explicitly answers both what it does and when to use it, with a 'Use when asked to ...' clause listing concrete trigger phrases.

Trigger Term Quality

Provides several natural quoted trigger phrases a user would actually say, including synonyms ('generate evals' / 'create evaluation scenarios') and 'prepare for tessl publish'.

Distinctiveness Conflict Risk

The Tessl-tile eval niche is clearly distinct, but generic triggers like 'test this skill' and 'measure skill value' carry minor overlap risk with broader testing/evaluation skills.
