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?

Beyond annotations (idempotent, non-destructive), the description discloses constraints like SMS 10/day cap, webhook auto-disable, and one-time secret return, adding significant behavioral 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?

Front-loaded with core action and prerequisites, but the description is dense with examples; could be slightly more streamlined without losing critical 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?

Covers prerequisites, types, delivery options, and return value adequately for a complex tool, but lacks explicit mention of error handling or idempotency confirmation.

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?

With 100% schema coverage, the description still enriches each parameter with concrete examples (e.g., sec_8k items codes) and delivery channel behaviors, surpassing the schema's basic descriptions.

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 explicitly states 'Create a proactive monitoring subscription' and distinguishes from sibling tools like 'list_subscriptions' and 'unsubscribe' by focusing on creation and subscription id return.

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?

Clearly states prerequisites (Pipeworx OAuth account) and provides detailed examples for each subscription type and delivery channel, guiding when to use specific parameters and alternatives.

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. The description adds valuable context: it returns 'category-bucketed example questions' with exact tool and argument shapes. 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, then explains the output and usage. It's informative but slightly long; a minor trim could improve conciseness without losing 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 tool's simplicity (1 optional param), rich annotations, and no output schema, the description is very complete: it explains what is returned, how to call it (with/without topic), and when to use. No gaps.

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 value by explaining the optional 'topic' parameter with examples ('finance', 'pharma', etc.) and that omitting it gives a cross-category spread. This goes beyond the schema 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: an onboarding entry point that returns category-bucketed example questions. It specifies the verb 'returns' and the resource 'example questions'. It distinguishes itself from sibling tools by advising to use it 'FIRST when you do not yet know what Pipeworx can do for you'.

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: 'the onboarding entry point for an agent that just connected' and 'Use this FIRST when you do not yet know what Pipeworx can do for you'. It also notes it can teach how to call meta-tools, providing clear usage context.

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 valuable context beyond annotations: ownership enforcement and deactivation (soft delete) with historical events retained via recent_alerts. 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?

Two concise sentences, front-loaded with the primary action, no fluff.

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?

Complete for a simple tool: single parameter, no output schema, annotations cover safety, description adds sufficient behavioral and ownership 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 coverage is 100% with parameter description adequate. The description adds no additional detail about the id parameter beyond what schema provides, meeting baseline but not exceeding.

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 action 'Cancel a subscription by id', specifies the resource (subscription), and distinguishes from siblings by mentioning ownership enforcement and deactivation behavior.

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?

Provides clear context: ownership enforced (only cancel own subscriptions) and soft delete behavior. Implicitly guides when to use, but does not explicitly contrast with alternative tools like unsubscribe vs. other actions.

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 the tool is read-only, idempotent, and non-destructive. The description adds important behavioral context: it returns a verdict (confirmed/refuted/etc.), extracted structured form, actual value with citation, and percent delta. It also notes that it replaces 4–6 sequential calls, explaining its composite nature. This supplements the annotations without 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 appropriately sized and front-loaded with user-facing examples. Every sentence serves a purpose: examples, scope, return values, and efficiency benefit. No extraneous information, making it concise and well-structured for quick parsing by 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 simple input schema (one required string) and no output schema, the description provides comprehensive context. It explains the tool's domain, output verdicts, structured response, citation format, and performance advantage. The agent can fully understand what the tool does and what to expect without needing additional cues.

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 for the single parameter 'claim' is 100%, so the description does not need to add much. The description provides examples of acceptable claim formats (e.g., "Apple's FY2024 revenue was $400 billion"), which helps clarify the expected input. However, this adds limited value beyond the schema's own description, earning a baseline score of 3.

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 claims against authoritative sources for company-financial data. It provides explicit example queries ("Is it true that...", "fact check", etc.) and specifies the domain (US public companies' revenue, net income, cash position via SEC EDGAR + XBRL), making the functionality unambiguous and well-differentiated from siblings.

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 tells when to use the tool: "Use whenever the agent needs to check whether something a user said is factually correct." It also mentions the supported domain (company-financial claims), providing clear context. However, it does not explicitly state when not to use it or suggest alternatives for other types of claims, which would strengthen the guidance.

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