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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint. The description adds detailed return structure (per-model: score, confidence, signals, raw_response, combined view) and explains the API key passthrough and cost implication. No contradiction.

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 two sentences plus a note, efficiently packed with key information. It is front-loaded with main purpose and quickly covers details.

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 no output schema, the description explains the return format per model and combined view, covers all parameters (100% schema coverage), and provides sufficient behavioral context for an agent to use the tool correctly.

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%, so baseline is 3. The description adds practical usage details beyond schema: default model, BYO key for Anthropic, and context disambiguation examples. This provides extra value for an agent.

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 verb 'probe', the resource 'LLMs', and the output 'score visibility (0-100)'. It distinguishes from siblings like 'ask_pipeworx' and 'scan_competitor_ai_presence' by focusing on AI visibility auditing.

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 context for use cases ('AI-marketing audits, pre-launch brand checks, competitive monitoring') and explains the key requirement for Anthropic probing (BYO key). It does not explicitly state when not to use or list alternatives, but the context is sufficient.

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 it routes to thousands of tools, fills arguments, returns structured answers with citations, and works on every tier. Annotations already mark readOnly, openWorld, idempotent, non-destructive; no contradiction.

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?

Front-loaded with key guidance and examples, but slightly verbose. Still well-structured and each sentence adds value.

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 complexity (6 params, no output schema), the description is comprehensive: covers use cases, alternatives, examples, and behavioral traits. No gaps.

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

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, openWorldHint, idempotentHint, destructiveHint. Description adds significant behavioral details: exact return structure {answer, evidence, confidence, source, fetched_at, refusal_reason}, list of possible refusal reasons, and the fact that it costs an extra LLM call. 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 moderately concise; each sentence adds value. It front-loads the purpose and usage, then details the return format and refusal cases. Could be slightly shorter but structured well for an AI agent.

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's complexity and the presence of annotations and schema, the description is complete. It explains the behavior, result format, refusal scenarios, and comparison with sibling tool ask_pipeworx. No output schema exists, but the description compensates by detailing the output structure.

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%, so baseline 3. Description mentions that the question parameter accepts multiple aliases (query, q, prompt, text, input), which adds slight semantic clarity beyond the schema. However, it does not provide additional meaning about how the question is interpreted.

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 function: a hallucination-resistant answer mode for high-stakes reads. It explains the routing, fetching, and extraction process. It also distinguishes itself from ask_pipeworx by mentioning the extra LLM call and refusal mechanisms.

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?

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?

Extensive behavioral details beyond annotations: resolver contract with confidence, classification system, fan-out logic, response shapes, safety short-circuits, resolution-rule risk. No contradiction with readOnlyHint and idempotentHint since it's a research/computation tool.

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

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?

The annotations indicate readOnly, openWorld, idempotent, and non-destructive. The description adds: for 'company' type it pulls latest 10-K financials from SEC EDGAR/XBRL with fiscal year handling; for 'drug' type, FAERS counts, FDA approvals, trial counts. Also mentions sorted results and citation URIs. No contradiction.

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?

Despite lacking an output schema, the description explains the response structure (opportunities[], partition_check, fill_check) and error handling (no args failure). It covers edge cases and provides sufficient context for an agent to use the tool effectively.

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%, and the description adds substantial meaning to both parameters: event mode uses slugs or full URLs, topic mode uses seed questions for cross-event scanning. Examples provided for both, enhancing understanding 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 clearly states the tool finds arbitrage opportunities on Polymarket via monotonicity violations and partition-sum checks. It distinguishes two modes (event and topic) and gives specific examples of usage, making the purpose unambiguous.

The description adds valuable behavioral context: it returns a subscription id, requires OAuth authentication, and details limitations (10/day sms cap, webhook auto-disable after 10 consecutive failures). These details go beyond what annotations provide, enhancing the agent's understanding of side effects and constraints.

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 detailed but well-structured, with the core purpose upfront followed by type and delivery details. It is slightly verbose due to inline examples, but each sentence serves a purpose in clarifying usage. Minor improvements could include separating type examples into a bulleted list for better scanability.

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's complexity (3 parameters, 2 required, nested objects, no output schema), the description covers all necessary aspects: purpose, prerequisites, type-specific parameters, delivery options with limitations, and return value ('Returns the new subscription id'). It is complete enough for an agent to understand and invoke the tool correctly without external references.

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?

The input schema has 100% description coverage, but the description adds significant meaning beyond the schema. For the 'type' parameter, it gives concrete examples and explains how to use items codes for sec_8k. For 'params', it provides detailed per-type examples. For 'delivery', it elaborates on sms/email/webhook specifics, including validation rules and signing secrets. This extra context is crucial for correct parameter construction.

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 primary function: 'Create a proactive monitoring subscription to a live-data event stream.' It specifies the verb (create), resource (subscription), and context (monitoring). The listed supported types and delivery channels further clarify the scope. This distinguishes it from sibling tools like 'list_subscriptions' and 'unsubscribe'.

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 context: requires a Pipeworx OAuth account, notes that anonymous/BYO cannot persist subscriptions, and lists supported types with detailed examples. It also explains delivery channel options and limitations (e.g., sms cap, webhook auto-disable). While it doesn't explicitly state when not to use this tool or name alternatives, the context of subscribing versus listing or unsubscribing is clear from sibling tool names.

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, openWorldHint, idempotentHint, destructiveHint. The description adds behavioral context: returns examples drawn from live catalog, with exact tool+argument shape, and that it is safe to call without side effects. 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 front-loaded with common queries and efficiently conveys purpose, usage, and return content. It is reasonably concise given the amount of information, though a few extra phrases could be trimmed.

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 fully covers the tool's functionality: it explains the return format (category-bucketed examples), invocation options, and the context in which it should be used. Without an output schema, the description adequately describes what to expect.

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 one optional parameter. The description adds meaning beyond the schema by explaining how to use it ('Omit for a cross-category spread') and providing example values. It clearly links the parameter to the behavior.

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 that the tool is the onboarding entry point, returns category-bucketed example questions, and explains its role in helping a new agent discover what Pipeworx can do. It explicitly distinguishes itself from siblings by positioning itself as the first tool to use when unsure.

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 states when to use ('Use this FIRST when you do not yet know what Pipeworx can do for you') and how to invoke it (no arguments or optional topic). It does not explicitly list when not to use, but the context implies alternatives are other tools.

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?

Adds context beyond annotations: deactivation instead of deletion, and that historical events remain available via 'recent_alerts'. Annotations already indicate non-destructive and idempotent, but description enriches understanding.

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?

Two concise sentences with front-loaded core action. No wasted words, efficient and clear.

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?

For a simple 1-param tool with good annotations and no output schema, the description fully covers purpose, constraints, and side effects (deactivation, historical data).

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 has 100% coverage for the single 'id' parameter with its description. Description adds little beyond 'by id', which is already implied. Baseline 3 is appropriate.

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?

Description clearly states 'Cancel a subscription by id' with a specific verb and resource. It distinguishes from sibling tools like 'subscribe' and 'list_subscriptions' by focusing on cancellation.

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?

Explicitly mentions ownership enforcement ('you can only cancel your own subscriptions') and clarifies that the row is deactivated, not deleted, providing guidance on when to use and implications.

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 declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint. The description adds behavioral details: returns a verdict and citation, replaces 4-6 sequential calls, and uses specific data sources. 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 front-loaded with clear examples and a list of verdicts. It is somewhat lengthy but every sentence adds value. Structure could be slightly tightened.

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 one simple parameter and no output schema, the description fully covers purpose, usage, return values, and data sources. It is complete for an agent to decide when and how to invoke.

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?

There's only one parameter (claim) with full schema description (100% coverage). The description's examples and scope add context but the schema already describes the parameter adequately. Baseline 3 is appropriate.

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: natural-language claim verification. It provides example phrases ('Is it true that...', 'fact check') and specifies the domain (company-financial claims). It distinguishes from siblings 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 says when to use ('whenever the agent needs to check...factually correct') and defines the supported scope (company-financial claims via SEC EDGAR + XBRL). It lacks explicit when-not-to-use guidance, but the scope limitation indirectly serves that purpose.

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