get_top_trading_strategies

Get the top-ranked short volatility and long volatility option trading strategies.

Returns two ranked lists — short_volatility (sell premium / theta strategies) and
long_volatility (buy premium / gamma strategies) — each containing up to `limit` tickers.

Each entry has the same fields as get_ticker:
- ticker, name, latest_price, page_url
- bullish_case, bearish_case, potential_outcomes, takeaway, analysis_date (AI-generated, when available)
- price_forecast_days, price_forecast_percent, price_forecast_lower/upper_bound_percent (when available)
- iv_rank_percentile (0-100, IV rank over past year, when available)
- short_vol_call, short_vol_put: best short volatility option packs (when available)
- long_vol_call, long_vol_put: best long volatility option packs (when available)

Sort options:
- "helium_rank" (default): Helium AI edge score — best overall expected value
- "odds_of_profit": Highest probability of profit
- "historical_performance": Best annualized historical P&L across backtested trades
- "reward_to_risk": Best reward-to-risk ratio
- "smallest_max_loss": Strategies with the smallest maximum possible loss

Args:
    sort: Ranking method (default "helium_rank"). One of: 'helium_rank', 'odds_of_profit',
          'historical_performance', 'reward_to_risk', 'smallest_max_loss'.
    limit: Number of results per strategy type (1-20, default 5).

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It discloses the return format, fields, sort options, and caveats like 'when available' and AI-generated content. It does not explicitly state there are no side effects, rate limits, or error behaviors, but for a get-style tool the disclosure is substantial.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the core purpose, then uses clear bullet-like sections for return fields and sort options. Despite its length, every section serves a purpose and the structure makes it easy to scan.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity—two ranked lists, five sort methods, and many output fields—the description covers the necessary detail for correct invocation. Defaults, limits, sort semantics, and field categories are all explained, making the tool self-contained for an agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, but the description fully compensates: it explains both `sort` (each enum value with meaning) and `limit` (range 1-20, default 5) in detail. This goes far beyond the bare schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource: 'Get the top-ranked short volatility and long volatility option trading strategies.' It clearly differentiates from sibling tools by focusing on ranked strategies rather than individual tickers or news, and further details the two output lists and sort options.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description clearly implies when to use this tool—when you need top-ranked long/short volatility strategies—and provides rich context about sorting and output. It does not explicitly compare alternatives or state when not to use it, but the purpose is clear enough for an agent to select it appropriately.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4.4/5.0
Disambiguation4/5

Most tools have clearly distinct purposes, but two pairs could cause confusion: get_all_source_biases vs. get_source_bias, and search_news vs. search_balanced_news. The descriptions explicitly differentiate them (list vs. single source; RSS vs. synthesized stories), so an agent can disambiguate with careful reading.

Naming Consistency5/5

All tool names follow a consistent verb_noun pattern using snake_case: get_* for retrievals and search_* for searches. Any variations (e.g., get_all_source_biases vs. get_source_bias) are natural qualifiers and don't break the pattern.

Tool Count5/5

With 10 tools spanning news bias analysis, options data, ticker data, and trading strategies, the count is well-scoped. Each tool has a distinct role and the set is neither too thin nor overloaded.

Completeness4/5

The surface covers the core workflows: searching news, analyzing bias at both article and source level, retrieving market data, options chains, and strategy rankings. Minor gaps exist, such as no direct way to fetch a full article by ID or list all news sources, but these are workarounds with existing tools.
