Quality

Content

57%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is well-organized with concrete grader commands and integration patterns, but workflow validation checkpoints are implicit and several steps use placeholder shells. Progressive disclosure is clean given the single-file, no-bundle structure.

Suggestions

Add an explicit validation checkpoint in the Evaluate step (e.g., 'If any eval FAILs, fix the code and re-run before reporting') to create a feedback loop.

Replace placeholder shells ('[Write code]', '[Run each capability eval, record PASS/FAIL]') with concrete, runnable instructions or marked-optional examples.

Consolidate the Example section so it illustrates rather than re-lists the Eval Workflow phases, removing the redundancy.

DimensionReasoningScore

Conciseness

Mostly terse and well-structured, but the Example section restates the Eval Workflow's Define/Implement/Evaluate/Report structure, adding redundancy that could be tightened.

2 / 3

Actionability

Provides many concrete, real commands (grep/npm graders, /eval subcommands, .claude/evals layout) but key workflow steps remain placeholder shells like '[Run each capability eval, record PASS/FAIL]' and '[Write code]'.

2 / 3

Workflow Clarity

The Define→Implement→Evaluate→Report sequence is clearly numbered, but the Evaluate step lacks a validate→fix→retry feedback loop, which caps workflow clarity at 2.

2 / 3

Progressive Disclosure

Content is organized into clearly headed sections with no nested or multi-level file references; no bundle files exist, and the single-file structure is appropriately navigable.

Description

57%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description identifies a clear, distinct niche but is weak on trigger terms and lacks an explicit 'Use when' clause, capping completeness and trigger quality at 2. It is readable but more abstract than action-specific.

Suggestions

Add an explicit 'Use when...' clause listing natural trigger phrases (e.g., 'Use when setting up evals, defining pass/fail criteria, or measuring agent reliability with pass@k').

Replace abstract framing with concrete verbs ('Define pass/fail criteria, measure pass@k, create regression suites') to lift specificity to 3.

Include common user phrasings like 'evals', 'agent reliability', or 'test my Claude Code task' to improve trigger-term coverage.

DimensionReasoningScore

Specificity

Names the domain (evaluation framework, EDD) and the high-level action ('implementing'), but does not list multiple concrete actions like defining pass/fail criteria or measuring pass@k.

2 / 3

Completeness

States what the skill does (formal evaluation framework) but provides no explicit 'when to use' trigger guidance, which caps completeness at 2.

2 / 3

Trigger Term Quality

Contains relevant terms ('evaluation', 'eval-driven development') but leans on jargon ('EDD principles') and lacks the natural phrases a user would say, with no 'Use when...' clause.

2 / 3

Distinctiveness Conflict Risk

The EDD/eval-driven-development niche is specific and unlikely to trigger for unrelated skills, with little overlap risk.
