Quality

Content

86%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 a tight, well-structured skill with executable commands, a complete output schema, and sensible error-recovery guidance. Minor conciseness and workflow-checkpoint refinements would bring it to the top level.

Suggestions

Tighten the IB_PORT precedence sentence into a compact precedence list (e.g. '--port > IB_PORT > default 7497') to trim prose.

Add an explicit checkpoint after listing expiries (e.g. confirm a non-empty expiry list before fetching a specific chain) to strengthen the workflow's validation loop.

DimensionReasoningScore

Conciseness

Mostly lean and operational, but the IB_PORT precedence rule and port-fallback paragraph are expressed in prose that could be tightened slightly; no concept padding of things Claude already knows.

4 / 5

Actionability

Provides copy-paste-ready executable commands, a complete argument table, and a full JSON output schema covering the common cases.

5 / 5

Workflow Clarity

Clear sequence (expiries then chain) with an explicit port-failure retry feedback loop and error guidance; minor gap is no explicit checkpoint confirming expiries succeeded before fetching the chain.

4 / 5

Progressive Disclosure

Well-organized sections under 50 lines with the single bundle file scripts/options.py referenced via an executable command; no nested references, easy to navigate.

Description

100%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 exemplary: third-person, specific, comprehensive, and clearly bounded to a niche. It answers both what the skill does and when to use it with concrete trigger phrasing.

DimensionReasoningScore

Specificity

Lists multiple concrete actions and fields (calls/puts, strikes, bids, asks, volume, implied volatility, model Greeks) across equities/ETFs and futures, giving comprehensive coverage of what the skill returns.

5 / 5

Completeness

Explicitly answers both 'what' (get option chain data with specific fields) and 'when' ('Use when user asks about options using IBKR data, futures options...') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Includes natural terms users would say ('options', 'IBKR data', 'futures options', 'real-time option quotes', concrete roots NQ/ES/CL/GC) with synonym-like coverage appropriate to broker data.

5 / 5

Distinctiveness Conflict Risk

Clearly scoped to IBKR option chains with concrete ticker roots and a broker prerequisite (TWS/IB Gateway), giving it a distinct niche with minimal overlap risk.
