The description is a single paragraph of 4-5 sentences, well-structured and front-loaded. Each sentence contributes, though it could be slightly more concise by listing types in bullet points. Still 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?

Given the complexity (3 params, nested objects, no output schema), the description covers prerequisites (OAuth account), constraints, type-specific params, delivery options and limits. It explains what the tool returns (subscription id). No gaps 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%, but the description adds significant meaning: for 'type', it gives concrete examples and item codes; for 'params', it details structures for each type; for 'delivery', it explains email validation, SMS cap, webhook HMAC signing and auto-disable. This goes well beyond the schema 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 clearly states the tool's purpose: 'Create a proactive monitoring subscription to a live-data event stream. Returns the new subscription id.' It uses a specific verb and resource, and distinguishes from sibling tools like list_subscriptions (listing) and unsubscribe (deleting).

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 context: requires Pipeworx OAuth account (anonymous+BYO cannot persist), lists supported types with examples, and details delivery channels with constraints (phone verification, SMS cap, webhook auto-disable). It does not explicitly state when not to use, but the context is clear enough for an AI agent to decide.

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, openWorldHint=true. The description adds valuable behavioral context: that it returns example questions with exact tool+argument shapes drawn from a live catalog, and that it serves as an entry point. No contradictions 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?

Despite its length, every sentence adds value. Starts with common user questions, then explains output, then usage guidance. Information is well-organized and front-loaded with the core purpose. No wasted words; it efficiently conveys purpose, usage, and output.

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 is highly complete given the tool's simplicity (1 optional param, no output schema). It covers purpose, when to use, what output to expect, and how to invoke with different arguments. No gaps remain for an agent to misunderstand the 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% with a single optional 'topic' parameter. The description adds significant meaning by explaining that omitting topic yields a cross-category spread, and lists valid topic values with examples ('finance', 'pharma', etc.), going 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 returns category-bucketed example questions to help users understand what to ask Pipeworx. It distinguishes from siblings by positioning it as an 'onboarding entry point' and listing specific categories, making its purpose unambiguous and differentiating it from other tools like 'ask_pipeworx' or 'discover_tools'.

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 instructs to use this tool 'FIRST when you do not yet know what Pipeworx can do for you'. Provides guidance on arguments: call with no arguments for full spread or pass a topic to focus. Implies when not to use (after familiarization) and hints at alternatives by mentioning 'meta-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 important behavioral details beyond annotations: ownership enforcement, deactivation (not deletion), and historical data retention via recent_alerts. Annotations already indicate non-read-only, non-destructive, and idempotent; description provides concrete 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?

Two efficient sentences: first states core action, second adds ownership and behavioral nuance. No extraneous words; front-loaded with verb.

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?

Comprehensive for a simple tool with one parameter. Covers action, constraint, and side effects (deactivation). Mentions connection to sibling 'recent_alerts'. However, does not specify return value (e.g., success indicator), which is a minor gap.

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 already fully describes the 'id' parameter as a UUID from subscribe. The description reiterates 'by id' but adds no new parameter-level meaning. 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?

Clearly states 'Cancel a subscription by id,' which is a specific verb+resource. Differentiates from sibling tools like 'subscribe' (create) and 'list_subscriptions' (list). Mentions ownership enforcement and deactivation, adding distinction.

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 notes that ownership is enforced ('you can only cancel your own subscriptions'), providing a clear constraint. Implicitly suggests using this for cancellation vs. other operations, but does not explicitly state when not to use or list 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, and destructiveHint. The description adds valuable context: it returns a verdict, structured form, actual value with citation, and percent delta, and notes that it 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 moderately sized and front-loaded with examples. It efficiently conveys purpose, scope, and outputs, though the list of example phrases could be slightly trimmed without losing clarity.

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 and no output schema, the description fully covers what the agent needs: domain, sources, output format, and performance benefit. 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?

Only one parameter exists with 100% schema coverage. The description enriches the parameter meaning by providing natural-language examples and clarifying the input format 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: natural-language claim verification against authoritative sources, specifically for company-financial claims. It provides example query forms and distinguishes itself from sibling tools by being a specialized, single-step verification tool.

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 'Use whenever the agent needs to check whether something a user said is factually correct' and specifies the scope (company-financial claims). While it doesn't explicitly exclude other uses, the scope is clear and the tool is well-suited for its intended purpose.

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