Schema coverage is 100%, but the description enhances understanding with concrete examples for each type (e.g., sec_8k items, polymarket_edge topic) and clarifies delivery behavior (email template, SMS verification, webhook HMAC). This adds meaning 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's purpose: 'Create a proactive monitoring subscription to a live-data event stream.' It specifies the return value ('Returns the new subscription id'), and the tool is clearly differentiated from siblings 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 extensive context on when to use this tool, including requirements (Pipeworx OAuth account), supported types, and delivery channels. While it does not explicitly compare to siblings, the prerequisites and constraints are well-explained.

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 read-only, idempotent, non-destructive, open-world. Description adds that the tool returns category-bucketed example questions with tool+argument shapes, and can be filtered by topic. 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 detailed but well-structured, front-loading the core purpose and listing supported topics. Could be slightly shortened without losing clarity, but remains effective.

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 single optional parameter and no output schema, the description fully covers when to use, what it returns, and how to customize the output. It is self-contained and leaves no ambiguity.

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% for the single parameter 'topic'. Description adds concrete examples ('finance', 'pharma', 'betting') and explains the effect of omitting vs providing the argument, adding value 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 is the onboarding entry point for 'What can I ask Pipeworx?' and lists alternative phrasings. It distinguishes from siblings like ask_pipeworx by explicitly positioning it as the first tool to use when unknown.

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 explicit instruction: 'Use this FIRST when you do not yet know what Pipeworx can do for you.' Also explains when to pass the optional topic argument. Lacks explicit when-not scenarios but context is very clear.

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 the operation is a deactivation, not deletion, and that historical events remain accessible via 'recent_alerts'. Annotations already indicate non-destructive (destructiveHint=false) and idempotent (idempotentHint=true); the description adds concrete 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?

Two concise sentences: first states the action and required parameter, second provides critical behavioral details. 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?

For a simple one-parameter tool with no output schema, the description fully covers purpose, required parameter, ownership constraint, and the non-destructive nature, connecting to related tools like 'recent_alerts'.

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 mentions 'by id', but does not add semantic value beyond what the schema's 'id' description already provides ('Subscription id (uuid) returned by subscribe'). Baseline 3 applies.

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 the verb 'Cancel' and the resource 'subscription by id'. It distinguishes from sibling tools like 'subscribe' (creation) and 'list_subscriptions' (listing) by specifying ownership enforcement and deactivation semantics.

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 guidance on ownership restriction ('only cancel your own subscriptions') and the effect of deactivation, implying it should be used when the user wants to stop receiving alerts but retain history. Lacks explicit comparison to alternatives like 'unsubscribe' vs 'delete'.

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 safe read operation (readOnlyHint, destructiveHint false). The description adds value by explaining the two pipelines (SEC EDGAR fast path vs. grounded pipeline) and the return value structure (verdict, value, citation, reasoning). It is transparent about behavior 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 that front-loads with example triggers and explains the tool's purpose. Every sentence adds value, covering usage, behavior, and return value. It is appropriately sized for the complexity of the tool.

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 (handling two types of claims), low parameter count, and absence of output schema, the description is highly complete. It explains the return value and reasoning, making it unnecessary to rely on additional fields.

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 both parameters. The description adds meaning by explaining the default and overriding behavior for tolerance_pct, and the natural-language nature of the claim parameter. This meets the baseline expectation without adding significant new semantics.

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 uses specific verbs ('validate claim', 'fact check', 'verify') and clearly identifies the resource ('natural-language claim verification against authoritative sources'). It distinguishes itself from sibling tools by being dedicated to claim verification and mentions replacing 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 states when to use this tool ('Use whenever the agent needs to check whether something a user said is factually correct') and provides examples. It differentiates between company-financial claims and other claims, explaining the handling for each. While it doesn't explicitly say when not to use it, 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.
