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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior. The description adds valuable context: that it probes multiple models, costs are involved for Anthropic (BYO key), and returns scored results. This extra detail is helpful but not required beyond annotations.

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

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

The description is concise (5 sentences) with clear structure: purpose first, then default behavior, optional parameters, return format, and use cases. No redundant or wasted text.

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

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

Given no output schema, the description adequately explains the return format (per-model object plus combined view). All parameters are described, and the use of models and API keys is clarified. The tool is self-contained and well-documented.

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

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

Schema description coverage is 100%, so parameters are already documented. The description adds meaning by explaining the default model (free), the need for _apiKey for Anthropic, and the disambiguation purpose of the context parameter. This adds value beyond the schema.

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

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

The description uses specific verbs ('probe', 'score visibility') and clearly identifies the resource (LLMs) and output (0-100 score per model). It also lists use cases (AI-marketing audits, pre-launch brand checks, competitive monitoring) that distinguish it from siblings like scan_competitor_ai_presence.

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

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

The description provides clear context for when to use this tool (brand audits, monitoring) and explains when to provide an API key ('if anthropic is in models'). However, it does not explicitly mention when not to use it or contrast with alternatives like scan_competitor_ai_presence.

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

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

Discloses that the tool orchestrates other tools ('picks the right tool, fills the arguments'), but given no annotations, provides no information on safety, side effects, or auth requirements. Adequate but not rich.

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

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive. The description adds substantial behavioral context beyond annotations: fan-out logic, response shapes, resolver contract with confidence levels, parent event extraction, news fallback fields, and safety blocking mechanisms. It does not contradict annotations.

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

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

The description is long (nearly 300 words) but well-structured with clear sections (CLASSIFIERS, FAN-OUT EXAMPLES, RESPONSE SHAPES, etc.). It front-loads the purpose, and every sentence adds value. However, the length could be trimmed by 30-40% without losing essential information, making it more concise for an agent scanning it.

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

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

Despite lacking an output schema, the description thoroughly covers return shapes (result.market, result.analysis, result.evidence) with detailed fields. It also explains edge cases (low-confidence matching, closed markets, wide spreads) and provides operational notes (news fallback, parent event extraction). This is highly complete for a complex tool.

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

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

Schema description coverage is 100%, so the schema documents parameters. The description adds meaningful context beyond the schema, such as the depth parameter controlling fan-out breadth and the include_raw parameter affecting response size. It also clarifies the market input formats, reinforcing but also extending the schema's explanations.

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

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

The description clearly states the tool's purpose: 'Research a Polymarket bet by pulling the relevant Pipeworx data for it in one call.' It includes specific verbs and resources, and the examples and classifiers further define scope. While siblings exist, the tool's unique combination of resolution, classification, and parallel fan-out distinguishes it effectively.

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

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

The description provides explicit usage examples: 'Use for "should I bet on X", "what does the data say about Y", or "is there edge in Z".' It also explains blocking behaviors for low-confidence and closed markets, guiding safe invocation. However, it does not explicitly state when to avoid this tool or name alternatives among siblings, which would improve clarity.

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

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

With no annotations, the description fully discloses behavior: it describes data sources (SEC EDGAR, FDA), return format (paired data + URIs), and that it is a read operation. It doesn't mention potential issues like rate limits or data staleness, but for a non-destructive tool this is acceptable.

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