The description clearly states it creates a proactive monitoring subscription and returns a new subscription ID. It distinguishes from sibling tools like 'unsubscribe' and 'list_subscriptions' by its action verb and purpose.

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 specifies that a Pipeworx OAuth account is required, indicating when the tool can be used. However, it does not explicitly state when to avoid this tool in favor of alternatives like 'list_subscriptions'.

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, destructiveHint=false. Description adds behavior: 'returns category-bucketed example questions... drawn from the live catalog,' and explains it's the onboarding entry point. No contradictions, and description enriches understanding 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 a single paragraph but effectively front-loaded with common user queries. Every sentence adds value, though it could be slightly more structured (e.g., bullet points for categories). No wasted words.

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?

No output schema exists, but description fully explains return format: 'category-bucketed example questions... each with the exact tool + argument shape.' It also mentions meta-tools and covers all relevant context for a simple one-parameter 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 coverage is 100% (single optional topic param). Description adds significant meaning: explains that omitting gives full spread, passing topic focuses, and lists nine valid categories ('finance, pharma, economics...'). This goes beyond the schema's generic 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: it returns category-bucketed example questions for Pipeworx, serving as an onboarding entry point. It uses specific verbs ('returns') and identifies the resource ('example questions'). It distinguishes itself from sibling tools by mentioning meta-tools and focusing on teaching what Pipeworx can do.

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?

Explicit guidance: 'Use this FIRST when you do not yet know what Pipeworx can do for you, or to learn how to call the meta-tools.' It also explains when to pass arguments ('pass topic to focus' vs omit for full spread). No confusion about when to use 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?

Adds context beyond annotations: row is deactivated not deleted, historical events stay available via recent_alerts. Annotations (idempotentHint=true, destructiveHint=false) are consistent.

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 sentences, direct and front-loaded, with no unnecessary words.

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 purpose, ownership, behavioral details, and parameter semantics adequately for a simple tool with no output schema.

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% description coverage for the single parameter, and description adds no extra meaning beyond 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?

Description clearly states 'Cancel a subscription by id' with specific verb and resource, and distinguishes from siblings like 'subscribe' and 'list_subscriptions'.

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 ownership constraint ('you can only cancel your own subscriptions'), which guides when to use, though lacks explicit comparison to 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 declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint. The description adds valuable context: it returns a verdict with specific categories, includes citations, and states it replaces 4-6 sequential calls. 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 concise and front-loaded with trigger phrases. It packs useful information into a single paragraph without wasted words. Minor improvement could be structuring with bullet points, but it is effective as is.

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 tool with one parameter and no output schema, the description covers purpose, usage, scope, return format, and efficiency. Annotations handle safety semantics. Minor gaps: no error handling or behavior for unsupported claim types, but still fairly complete.

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 only parameter 'claim' has a clear description in the schema with examples. The description adds limited extra meaning beyond the schema's description, but it does reinforce example types. Schema coverage is 100%, so 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 explicitly states the tool's purpose: natural-language claim verification. It provides specific verbs and trigger phrases (e.g., 'fact check', 'verify the claim'), clearly distinguishing it from sibling tools like deep_research or compare_entities. The resource (authoritative sources) and output (verdict) are clearly defined.

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 clearly states when to use the tool: 'whenever the agent needs to check whether something a user said is factually correct'. It also specifies the current scope (company-financial claims for public US companies). However, it does not explicitly exclude use cases when it should not be used (e.g., claims outside scope) or mention alternative tools.

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