pair-trade-screener

Statistical arbitrage tool for identifying and analyzing pair trading opportunities. Detects cointegrated stock pairs within sectors, analyzes spread behavior, calculates z-scores, and provides entry/exit recommendations for market-neutral strategies. Use when user requests pair trading opportunities, statistical arbitrage screening, mean-reversion strategies, or market-neutral portfolio construction. Supports correlation analysis, cointegration testing, and spread backtesting.

Quality

Content

65%

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

The content is highly actionable with concrete executable code, commands, and a clear 8-step workflow, but it is verbose and duplicates reference-level detail inline in SKILL.md. Tightening the overview and moving concept explanations into the existing reference files would improve both conciseness and progressive disclosure.

Suggestions

Trim the concept-explanation prose (e.g., the 'Why Cointegration Matters' bullets, correlation/p-value/z-score interpretation tables) since Claude already knows these; keep only the project-specific thresholds.

Move the detailed statistical methodology and interpretation tables into references/methodology.md and references/cointegration_guide.md, leaving SKILL.md a lean overview that points to them.

Add explicit validate->fix->retry feedback loops for the batch screening and data-validation steps (e.g., 'if data validation fails, re-fetch missing symbols and re-check') to lift workflow clarity.

DimensionReasoningScore

Conciseness

The ~620-line body restates concepts Claude already knows (what pair trading is, what correlation vs cointegration mean, beta's role) and includes textbook interpretation tables, so it is mostly efficient with a concrete core but padded with unnecessary explanation.

2 / 3

Actionability

Provides fully executable, copy-paste-ready material: a real FMP API endpoint, runnable bash commands for the bundled scripts, real Python (statsmodels adfuller), explicit formulas, and concrete parameter/output schemas.

3 / 3

Workflow Clarity

The 8-step sequence with objectives and validation criteria is clear, but this is a batch screening operation without explicit validate->fix->retry feedback loops, which caps workflow clarity at 2 per the batch-operations guideline.

2 / 3

Progressive Disclosure

Real one-level-deep bundle files (references/methodology.md, references/cointegration_guide.md, scripts/find_pairs.py, scripts/analyze_spread.py) are clearly signaled, but detailed methodology that belongs in those references is duplicated inline, making SKILL.md partially monolithic rather than a lean overview.

Description

100%

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 a strong, third-person statement of concrete capabilities with an explicit 'Use when' trigger clause and distinctive, natural-language trigger terms. It clearly answers both what the skill does and when to use it without padding or over-claims.

DimensionReasoningScore

Specificity

Lists multiple concrete actions in third person ('Detects cointegrated stock pairs', 'analyzes spread behavior', 'calculates z-scores', 'provides entry/exit recommendations'), matching the comprehensive multi-action anchor.

3 / 3

Completeness

Explicitly answers both what it does and when to use it via an explicit 'Use when user requests...' clause, matching the score-3 what-and-when anchor.

3 / 3

Trigger Term Quality

Includes natural phrasings a user would actually say ('pair trading opportunities', 'statistical arbitrage screening', 'mean-reversion strategies', 'market-neutral portfolio construction') with good coverage and no major variations missing.

3 / 3

Distinctiveness Conflict Risk

Highly specialized niche (statistical arbitrage / cointegration / z-scores / spread backtesting) with distinctive triggers that are unlikely to fire for other skills.
