breadth-chart-analyst

This skill should be used when analyzing market breadth charts, specifically the S&P 500 Breadth Index (200-Day MA based) and the US Stock Market Uptrend Stock Ratio charts. Use this skill when the user provides breadth chart images for analysis, requests market breadth assessment, positioning strategy recommendations, or wants to understand medium-term strategic and short-term tactical market outlook based on breadth indicators. All analysis and output are conducted in English.

Content

73%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 body is exceptionally actionable with a well-sequenced, validated workflow and clearly signaled one-level references. Its main weakness is verbosity: the same critical warnings and error-prevention guidance are repeated across three separate sections, inflating the token budget without adding capability.

Suggestions

Consolidate the repeated trend-reading warnings: keep the detailed checks in Step 4.1.5 and reduce 'Common Analysis Errors' and the Step 8 QA checklist to concise cross-references rather than restating the full guidance.

Move the Chart 1/Chart 2 element descriptions and backtested strategy rules (which duplicate references/breadth_chart_methodology.md) into the reference file, keeping SKILL.md as a concise overview that points to it.

Trim the redundant 'Language Note' / 'IMPORTANT: All analysis and output must be in English' reminders — stated once in the overview is sufficient given the dedicated Special Notes section.

Dimension	Reasoning	Score
Conciseness	The 660-line body is noticeably padded: the same guidance (8MA vs 200MA color confusion, rightmost-data-point focus, death/golden cross, pink background, 2-3 period confirmation) is repeated three to four times across Step 4.1.5, 'Common Analysis Errors', and the Step 8 QA checklist, creating several redundant sections without adding new information.	2 / 5
Actionability	Highly actionable for an analysis skill: concrete thresholds (73%, 23%, 10%, 40%), explicit confirmation rules (2-3 consecutive periods), defined signal statuses (CONFIRMED/DEVELOPING/FAILED/NO SIGNAL), file-naming conventions, and three fully worked examples with specific percentages cover the common cases.	5 / 5
Workflow Clarity	Steps 1-8 are clearly sequenced with explicit validation checkpoints — 'MANDATORY CROSS-CHECK', 'FINAL SANITY CHECK', the 14-item QA checklist, and a failed-reversal feedback loop that sends the analyst back to re-examine trend direction.	5 / 5
Progressive Disclosure	Bundle references are clearly signaled one level deep ('Read:', 'View:', 'Read and use as template:') with a Resources section describing each file, but the body inlines substantial chart-element and strategy detail that duplicates the bundled methodology reference rather than deferring to it.	4 / 5

Description

87%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 strong: it names a distinct niche, lists several concrete capabilities, and provides an explicit multi-trigger 'Use when' clause answering both what and when. Voice is appropriately third person and it avoids vague fluff.

Dimension	Reasoning	Score
Specificity	Names the domain (two specific breadth charts) and lists several concrete actions — 'analyzing market breadth charts', 'market breadth assessment', 'positioning strategy recommendations', 'understand medium-term strategic and short-term tactical market outlook' — with only minor coverage gaps around concrete deliverables.	4 / 5
Completeness	Explicitly answers both 'what' (analyzing/assessing breadth charts, positioning, outlook) and 'when' via a concrete 'Use this skill when the user provides breadth chart images for analysis, requests market breadth assessment, positioning strategy recommendations, or wants to understand...' trigger clause.	5 / 5
Trigger Term Quality	Good keyword coverage with natural phrases users would say ('breadth chart images for analysis', 'market breadth assessment', 'positioning strategy recommendations'); a few common synonyms or variations are missing, keeping it just below comprehensive.	4 / 5
Distinctiveness Conflict Risk	Clear niche tied to two named charts (S&P 500 Breadth Index 200-Day MA and US Stock Market Uptrend Stock Ratio) with distinct triggers, giving minimal conflict risk with other skills.	5 / 5
