yellow-bell-calculation-method

Use when establishing the fundamental pitch standard (黄钟) or deriving all twelve pitch pipes. Calculates the 9-cun base unit from powers of 3 and links musical tuning to weights, measures, and seasonal timing.

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.

A concise, well-structured single-purpose skill with concrete calculations and an explicit validation section. Minor redundancy in the overview and partial enumeration of the twelve pitches are the only weak points.

Suggestions

Merge or remove the redundant restatement of Yellow Bell as the fundamental pitch between the opening line and the Overview section.

Enumerate all twelve successive pitches (or give the general recurrence) instead of listing only four and saying 'Continue through all twelve pitches'.

Add a one-line recovery guidance for what to do if a derived pitch fails its validation check.

DimensionReasoningScore

Conciseness

Mostly lean and assumes competence, but the opening line and the Overview section redundantly restate that Yellow Bell is the fundamental pitch from which others are derived.

4 / 5

Actionability

Concrete fractions (2/3, 8/9, 16/27, 64/81) and the explicit 3^9 = 19683 / 9 寸 formula give executable guidance; the minor gap is that only 4 of 12 successive pitches are enumerated before 'Continue through all twelve pitches'.

4 / 5

Workflow Clarity

A clear sequence (base → successive pitches → formula → application) with an explicit Validation section of three verification checks, though there is no error-recovery feedback loop (acceptable here as it is a non-destructive calculation).

4 / 5

Progressive Disclosure

Under 50 lines, single-purpose, with no need for external references; content is organized into well-labeled sections (Overview, Base Calculation, Mathematical Formula, Key Principles, Application, Validation), meeting the simple-skill exception.

Description

92%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.

A strong, specific description with an explicit trigger clause, concrete actions, and a clear niche. Only slightly lacking in broader synonym coverage for trigger terms.

DimensionReasoningScore

Specificity

Names multiple concrete actions — 'establishing the fundamental pitch standard', 'deriving all twelve pitch pipes', 'Calculates the 9-cun base unit from powers of 3', 'links musical tuning to weights, measures, and seasonal timing' — covering the method comprehensively.

5 / 5

Completeness

Explicit 'Use when...' clause answers when, while 'Calculates the 9-cun base unit from powers of 3 and links musical tuning to weights, measures, and seasonal timing' clearly answers what, both with concrete triggers.

5 / 5

Trigger Term Quality

Good coverage of natural niche terms — '黄钟', 'fundamental pitch standard', 'twelve pitch pipes', 'weights, measures', 'seasonal timing' — but a few related natural synonyms (e.g. 律管/音律) are absent.

4 / 5

Distinctiveness Conflict Risk

A highly specific niche (黄钟/Yellow Bell pitch calculation) with distinct triggers and no realistic overlap with other skills; minimal conflict risk.
