Quality

Content

78%Weight 40%Scale 1-5

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

The content is a compact, well-structured instruction skill with concrete measurements, a verbatim prayer, an interpretation table, and an explicit verification checklist. It stops short of full marks on actionability and workflow_clarity because a few procedural details (e.g., drill-mark technique) and an error-recovery loop are not specified.

Suggestions

Add a brief concrete detail on creating drill marks (tool, pattern, depth) so the procedure is fully executable.

Add a short feedback loop in Verification: if a check fails, state what to do (e.g., re-cleanse the shell, repeat on an allowed day) to raise workflow_clarity.

Trim the 'Expected Outcomes' list or fold it into Interpretation to remove minor redundancy.

DimensionReasoningScore

Conciseness

The body is mostly lean with well-organized sections and only light orienting text in the Overview; the long prayer quote earns its tokens because it must be recited verbatim, leaving just minor trimming opportunities in 'Expected Outcomes'.

4 / 5

Actionability

Guidance is concrete and specific (1.2-foot shell, named prohibited days 子/亥/戌, face north, burn 正身 then 正足 three times, verbatim prayer, a classification table), with only small gaps such as how to create the drill marks.

4 / 5

Workflow Clarity

Preparation and Procedure are clearly sequenced, and a dedicated Verification section provides explicit checkpoints (length, prohibited days/times, crack classification), though an explicit error-recovery feedback loop is not spelled out.

4 / 5

Progressive Disclosure

The skill is a single well-organized SKILL.md under 50 lines with no external references needed; section headers cleanly separate preparation, procedure, prayer, interpretation, and verification.

Description

78%Weight 40%Scale 1-5

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 is well-constructed: it opens with an explicit 'Use when' trigger, enumerates several concrete sub-tasks, and occupies a clearly distinct niche. It falls just short of top marks on completeness and trigger coverage because the 'when' relies on a single trigger phrase and synonym coverage is thin.

Suggestions

Expand the 'when' clause to list additional natural trigger phrases users might say (e.g., 'interpreting crack patterns', 'performing 龟卜', 'divining with turtle shells') to lift trigger_term_quality and completeness.

Replace the generic verb 'Covers' with stronger action verbs ('Prepare shells', 'Recite prayers', 'Apply heat', 'Interpret cracks') to push specificity toward comprehensive.

DimensionReasoningScore

Specificity

Lists several specific concrete actions ('shell preparation', 'ritual prayer recitation', 'heat application for crack patterns', 'interpretation of crack positions') plus prohibited days, giving good coverage with only minor abstraction in the verb 'Covers'.

4 / 5

Completeness

Both 'what' ('Covers shell preparation...interpretation of crack positions') and 'when' ('Use when performing or analyzing...') are present and explicit, but the 'when' clause is a single trigger phrase rather than a fully enumerated set of trigger conditions.

4 / 5

Trigger Term Quality

Natural domain terms are present ('performing or analyzing ancient Chinese turtle shell divination', '龟卜'), giving good keyword coverage for the niche, though common synonym variations are limited.

4 / 5

Distinctiveness Conflict Risk

The trigger targets a highly specific niche (ancient Chinese turtle shell divination / 龟卜) with distinct terminology, making conflict with other skills minimal.
