Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, but the description adds substantial meaning: detailed examples for each type in the enum, parameter structures for each type, and comprehensive delivery channel behavior including webhook HMAC signing and auto-disable conditions. This goes far 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 creates a proactive monitoring subscription to a live-data event stream and returns the new subscription ID, distinguishing it from sibling tools like list_subscriptions and unsubscribe. It also lists supported types with examples.

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 the need for a Pipeworx OAuth account and explains delivery channel limitations (SMS cap, webhook auto-disable), providing practical usage context. It lacks explicit 'when not to use' but implies it through sibling tool 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?

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds context about the output structure (category-bucketed questions with tool calls) and the source (live catalog). It does not contradict annotations. Minor gap: no mention of error handling for invalid topics, but the schema provides enums? Actually no enums in schema, but the description lists valid topics explicitly.

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 informative but somewhat long (multiple lines). It front-loads the purpose with common user questions, which is effective. Every sentence adds value, but could be slightly more compact without losing information.

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, so the description compensates by describing the output structure (category-bucketed questions with tool calls). It also explains the tool's role as an onboarding entry point. Given the single optional parameter and simple output, this is nearly complete; only missing is what happens on invalid topic input.

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 clear description of the only parameter (topic). The description adds meaning by listing the valid values ('finance | pharma | economics ...') and explaining the effect of omitting vs passing an argument. This goes beyond the schema's minimal 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 is the onboarding entry point, returning category-bucketed example questions with tool+argument shapes. It uses specific verbs and resource references ('returns category-bucketed example questions'), and distinguishes from siblings like ask_pipeworx and discover_tools by positioning itself as a meta-tool for exploring capabilities.

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 tells when to use: 'Use this FIRST when you do not yet know what Pipeworx can do for you, or to learn how to call the meta-tools.' Also explains when to pass a topic to focus the results. No exclusions needed given its onboarding role.

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 value beyond annotations by explaining that the row is deactivated (not deleted) and that historical events remain available, which is critical context for the agent.

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 key action, no unnecessary words or redundancy.

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 parameter, no output schema, and adequate annotations, the description fully covers purpose, usage, and behavioral nuances.

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 context ('returned by subscribe') linking the parameter to the sibling tool, which is helpful 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 action ('Cancel a subscription by id') and resource, distinguishing it from sibling tools 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?

Explicitly mentions ownership enforcement ('you can only cancel your own subscriptions') and the soft-delete behavior, providing clear guidance on when to use and what to expect.

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=false, so the safety profile is clear. The description adds substantial behavioral context: it returns a verdict (confirmed, approximately_correct, etc.), extracted structured form, actual value with citation, and percent delta. It also explains it replaces multiple sequential calls, implying efficiency. 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 front-loaded with the core use case and uses clear examples. It is somewhat verbose with multiple input phrase examples and a detailed list of return fields, but every sentence adds value. Could be slightly more concise, but overall well-structured.

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 of claim verification and the absence of an output schema, the description fully compensates by detailing the return fields (verdict, structured form, actual value, citation, percent delta). It also explains the tool's functionality and data sources. The one required parameter is well-documented. The description is complete for the tool's purpose.

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 single parameter 'claim' has 100% schema coverage with a clear description and examples. The tool description provides additional domain context (company-financial claims) but does not add meaning beyond what the schema already provides for the parameter itself. 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 against authoritative sources for company-financial claims. It provides specific example inputs like 'fact check' and 'verify the claim that…' and outlines the returned verdict types. It distinguishes from siblings by noting it replaces 4-6 sequential calls, making its unique value clear.

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 domain (company-financial claims via SEC EDGAR + XBRL). However, it does not explicitly state when not to use it or mention alternative tools among siblings, which would have made it a 5.

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