The description explicitly states its use case ('Built for 'what should I bet on today'') and explains the three segments. It mentions that fed bets are excluded from ranking with a rationale. While it doesn't explicitly state when not to use it, the context is clear enough.

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?

Annotations already indicate readOnlyHint, openWorldHint, idempotentHint, and non-destructive behavior. The description adds substantial behavioral context: the response structure (leg-by-leg prices, spread array), safety fields (compatibility_warning, temporal_alignment), and explanations of when spreads are meaningless (e.g., mismatched bet shapes, temporal gaps). There is no contradiction with 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 comprehensive but somewhat lengthy; however, every sentence adds value. It is well-structured with bolded section headers (TWO MODES, RESPONSE, SAFETY FIELDS) that aid scanning. Minor redundancy could be trimmed, but overall it efficiently conveys complex information.

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 the tool has no output schema, the description fully explains the response structure (leg prices, spreads, top_spreads_pp) and safety fields (compatibility_warning, temporal_alignment, skipped counters). It covers edge cases and the conditions under which spreads are meaningful, making it self-contained for an AI agent.

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 coverage is 100% with all three parameters described. The description adds value by listing the exact topic shortcuts and explaining the overriding behavior of explicit tickers over topic mapping. This enriches the schema without repeating it, though the schema already provides adequate descriptions for each parameter.

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 identifies the tool as a cross-venue spread calculator between Kalshi and Polymarket for the same resolving question. It explicitly states two modes (topic shortcuts and explicit event tickers) and differentiates from siblings like 'polymarket_arbitrage' by its specific focus on cross-venue comparison.

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 guidance on when to use each mode: 'topic' for 10 pre-mapped shortcuts and explicit tickers for custom pairings.

Schema description coverage is 0%, and the description does not explain the 'username' parameter. The description fails to add meaning beyond the schema's structural definition.

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 'Public profile.' is a noun phrase without a verb, making it unclear whether the tool retrieves, updates, or otherwise interacts with a profile. It does not state the action performed on the resource.

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?

No guidance is provided on when to use this tool versus sibling tools like 'entity_profile' or 'user_recent_submissions'. The description lacks context about appropriate use cases.

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?

Annotations already declare the tool as read-only, idempotent, and non-destructive. The description adds the word 'accepted' but does not disclose behaviors beyond annotations, such as ordering, pagination, or time constraints. Since annotations cover safety, the description provides minimal additional context.

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?

While the description is very short, it is under-specified rather than concise. A single phrase with no additional structure fails to provide value, and the brevity comes at the cost of completeness.

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?

The description lacks essential context for effective tool usage. With an output schema present, return structure is covered elsewhere, but input parameters are undocumented and usage context is missing. The description is not complete enough given the tool's complexity and sibling context.

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 0%, meaning the JSON schema provides no description for parameters. The tool description also fails to explain the 'limit' or 'username' parameters, leaving the agent without any semantic guidance. This is a critical gap for a two-parameter tool.

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 'Recent accepted submissions' is vague. It does not specify what kind of submissions (e.g., code, forms) or provide context about the user scope. Among sibling tools like 'user_solved' and 'user_profile', the purpose is not clearly distinguished.

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?

There is no guidance on when to use this tool versus alternatives. No description of context, prerequisites, or exclusions. The agent receives no help in deciding when to invoke this tool.

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?

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. However, the description adds no additional behavioral context—e.g., whether counts are real-time, cached, or limited to a certain time span. For a low-annotation-coverage tool, the description should provide more behavioral details.

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 excessively terse—a single phrase without structure. While conciseness is valued, here it sacrifices essential information. The description could benefit from a sentence structure that includes subject, verb, and object.

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 that an output schema exists, the description does not need to detail return values. However, it fails to provide context about the domain (e.g., platform like LeetCode), what 'solved' means, or any temporal or filtering scope. The tool has only one parameter, yet the description adds minimal value beyond the name.

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 coverage is 0%, meaning the input schema provides no descriptions. The description does not explain the 'username' parameter beyond its presence in the schema. It does not specify format, constraints, or relationship to the output. This is a critical gap.

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 'Solved counts by difficulty' clearly indicates the tool returns counts of solved items grouped by difficulty. The resource (solved counts) and verb (implicitly 'get') are identifiable. It distinguishes itself from siblings like 'user_recent_submissions' and 'user_profile' by focusing on counts per difficulty, but lacks explicit mention that it is per user, which is inferred from the required 'username' parameter.

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?

No usage guidance is provided. The description does not specify when to use this tool versus alternatives such as 'user_recent_submissions' or 'compare_entities'. There are no contextual cues about prerequisites or appropriateness.

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?

Annotations already provide readOnlyHint, idempotentHint, openWorldHint, and destructiveHint. The description adds behavioral context: it uses SEC EDGAR + XBRL, returns specific verdicts with citations, and replaces multiple sequential calls. No contradictions.

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 relatively long but each sentence adds value. It front-loads with trigger phrases, then explains use case, domain, output, and efficiency. It could be slightly more concise but remains well-structured.

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 the tool has one parameter, no output schema, and the description explains output and domain limitations, it is fairly complete. It covers purpose, usage, return values, and data sources. Missing error handling info, but overall sufficient.

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% for the single 'claim' parameter. The description adds meaning by explaining natural-language format, giving examples, and clarifying the domain and output details, which goes beyond the schema's basic description.

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: verifying natural-language factual claims, specifically company-financial claims for US public companies. It uses specific verbs like 'verify', 'check', 'confirm or refute', and distinguishes from sibling tools by noting it replaces multiple sequential calls.

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 explicitly says to use it 'whenever the agent needs to check whether something a user said is factually correct' and specifies the domain limitation to company-financial claims. It does not explicitly mention alternatives among siblings, but the context is clear.

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