It does not fully address idempotency (whether duplicate subscriptions are prevented) but adds useful behavioral context 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 well-structured and every sentence adds value, but it is somewhat lengthy due to detailed examples. It could be more concise while retaining clarity, but it remains efficient for the complexity.

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 (multiple nested parameters, no output schema), the description covers purpose, usage, constraints, and examples. It mentions the return value (subscription id) but could elaborate on error cases or idempotency behavior. Overall, it is largely 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?

Schema coverage is 100% with clear descriptions. The description adds significant value by providing concrete examples for each subscription type's params and delivery channel details, including constraints and formatting, which aids correct parameter construction.

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 and returns the subscription id. It lists supported event types with detailed examples, differentiating it from sibling tools like list_subscriptions, unsubscribe, and recent_alerts.

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 and that anonymous/BYO cannot persist subscriptions. It details delivery channels, limits (SMS 10/day), and webhook behavior. However, it does not explicitly indicate when not to use this tool (e.g., for historical data) but provides sufficient context given sibling 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?

Annotations already indicate readOnly, idempotent, openWorld. The description adds value by detailing the return structure: 'category-bucketed example questions with exact tool + argument shape'. 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 a single paragraph but front-loaded with trigger phrases. It covers all necessary information without redundancy, but could be slightly more 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?

The description fully explains the return format (example questions with tools) and use case, compensating for the lack of an output schema. It mentions the live catalog, making the context 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?

Schema coverage is 100% with a description for topic. The description further explains the topic parameter's allowed values ('finance, pharma, etc.') and the behavior when omitted ('full spread'), adding 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 identifies the tool as the onboarding entry point, specifying it returns example questions. It uses specific verbs ('returns') and resources ('category-bucketed example questions'), and distinguishes itself from siblings by stating 'Use this FIRST'.

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 tool: 'when you do not yet know what Pipeworx can do for you' and 'to learn how to call the meta-tools'. It also implies when not to use it by framing it as a first step.

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?

The annotations indicate not destructive and idempotent. The description adds the important detail that the row is deactivated (not deleted) and ownership is enforced, providing behavioral context beyond the 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 sentences, front-loaded with the action. Every sentence adds value—no fluff. Ideal conciseness.

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 tool with one required parameter and no output schema, the description covers what happens (deactivation, ownership) and refers to related function (recent_alerts). Complete in 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?

The input schema has 100% coverage for the single parameter 'id', fully describing it as a uuid from subscribe. The description adds no further parameter information, 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 starts with 'Cancel a subscription by id,' which is a specific verb+resource pair. It also clarifies ownership enforcement and that the row is deactivated, not deleted, distinguishing it 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?

The description states ownership enforcement, indicating when this tool is appropriate (cancelling own subscriptions). It does not explicitly list when not to use it or mention sibling tools, but for a simple cancellation tool the guidance is sufficient.

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 substantial behavioral context: replaces multiple sequential calls, returns verdict with citations and reasoning, and explains the two processing pipelines.

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 dense paragraph that front-loads the core purpose with example trigger phrases. Every sentence adds useful context. Could be slightly more structured (e.g., bullet points for verdict types) but remains efficient.

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 2-parameter tool with no output schema, the description fully covers input semantics, processing logic, output structure, and usage scenarios. It compensates for lack of output schema by detailing return verdicts.

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 how tolerance_pct overrides implied wording (e.g., 'set 1–2 for hallucination detection') and clarifying default behavior.

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 defines the tool as claim verification with specific examples and distinguishes between two processing paths (SEC EDGAR for financial claims, grounded pipeline for others). It uses strong verb-resource pairs like 'validate claim' and explains the output verdict types.

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 states 'Use whenever the agent needs to check whether something a user said is factually correct.' Provides contextual cues for financial vs other claims. While it doesn't explicitly list when not to use, the purpose is narrowly defined and no direct sibling alternative exists.

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