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 when to use: when a record is too large for the prompt. Provides examples like SEC 10-K and articles. Does not explicitly list when not to use, but 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.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations declare readOnlyHint=false, idempotentHint=true, destructiveHint=false. The description adds significant context: OAuth requirement, return of subscription id, detailed delivery channel constraints (email, SMS with caps, webhook with HMAC and auto-disable after 10 failures). 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 well-structured and front-loaded with purpose and requirements. It is longer than minimal but each sentence adds value, covering types and delivery channels efficiently. Slightly less concise due to detail but appropriate 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 3 params (2 required), nested objects, and no output schema, the description is highly complete: covers all types, delivery channels, prerequisites, return value (subscription id), and unique behaviors (e.g., webhook secret issued once, auto-disable). 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?

With 100% schema coverage, baseline is 3, but description adds extensive meaning beyond schema: example values for each type (e.g., items for sec_8k, topic for polymarket_edge), delivery channel details (phone verification, webhook signing), and constraints. This greatly enhances parameter understanding.

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 subscription id. It distinguishes from siblings like list_subscriptions (listing existing) and recent_alerts (pulling events) by focusing on creation.

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 clear context on when to use: requires a Pipeworx OAuth account, and anonymous/BYO cannot persist subscriptions. It indirectly guides usage by detailing types and delivery channels, but does not explicitly state when not to use or compare 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=true, idempotentHint=true, and the description adds behavioral context: output format (category-bucketed with tool+argument shapes), source (live catalog), and behavior with/without topic. 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 well-structured, starting with common user queries, then defining the tool, then describing output and usage. It is comprehensive without being overly verbose; every sentence adds value.

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 role as an onboarding entry point, the description covers key aspects: when to use, how to call, what to expect (category-bucketed examples with tool+argument shapes). It does not detail exact output structure, but that is acceptable given 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 coverage is 100% with a description for the topic parameter. The description adds value by listing possible values for topic and explaining the effect of omitting it, which goes beyond the schema's basic 'Optional focus area'.

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 the onboarding entry point, stating it returns category-bucketed example questions with tool+argument shapes. It distinguishes itself from siblings by explicitly saying 'Use this FIRST' and naming meta-tools like ask_pipeworx, entity_profile, etc.

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 when to use ('when you do not yet know what Pipeworx can do') and how to call (with or without topic parameter). It also tells the agent to use it first before exploring meta-tools, providing clear 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?

The description adds value beyond annotations by detailing the return format (unix_seconds, production_types with data arrays) and noting timestamp alignment. Annotations already indicate read-only, idempotent, and non-destructive behavior, which the description complements.

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 extremely concise (two sentences) and front-loaded with the main purpose. Every word contributes meaning, with no 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 no output schema, the description adequately explains the return structure. Combined with full schema coverage and clear annotations, the description is complete for the tool's complexity.

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% description coverage, so the schema itself explains parameters. The description adds a note on country code format (2-letter lowercase) but does not significantly enhance understanding beyond the schema, warranting a baseline score of 3.

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 total electricity generation/load for a country over a date range, with a specific verb and resource. However, it does not differentiate from sibling tools like electricity_price or installed_power, which have distinct purposes.

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 no guidance on when to use this tool versus alternatives, such as suggesting it for aggregated generation data versus electricity_price for pricing or installed_power for capacity. An explicit context of use is missing.

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 description discloses that the action is a soft deactivation, not deletion, and that historical events remain available. Annotations already indicate mutability and idempotency, so description adds valuable context on ownership and data retention.

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, no filler, front-loaded with the action and key constraints. Every clause adds value.

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 detailed annotations, the description covers purpose, ownership, and soft-delete behavior adequately. It could optionally mention the success response shape but is otherwise 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 schema provides 100% coverage with a clear description of the 'id' parameter. The description adds context that ownership applies, meaning only valid subscription ids owned by the user can be used.

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' and resource 'subscription by id', and distinguishes from sibling tools like 'subscribe' and 'list_subscriptions' by specifying cancellation and ownership enforcement.

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?

It explains when to use (to cancel a subscription) and emphasizes ownership constraint. However, it does not explicitly mention when not to use or compare with alternatives like permanent deletion.

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 the tool is read-only, idempotent, and non-destructive. The description adds valuable behavioral context: it is a composite tool that replaces multiple steps, returns a verdict with citation and delta, and is limited to US public company financial claims. 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?

The description is somewhat lengthy but every sentence adds value: trigger phrases, use case, domain scope, return components, and efficiency benefit. It is well-structured with front-loaded trigger phrases. Slightly more verbose than strictly necessary, but not wasteful.

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 single-parameter tool with no output schema and comprehensive annotations, the description covers all essential aspects: purpose, usage, return value components (verdict, citation, delta), domain limitations, and efficiency benefits. Nothing important is missing given the tool's complexity and the available structured 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?

The schema provides 100% coverage for the single parameter 'claim' with a description. The tool description offers example claims and clarifies the parameter's natural-language nature, but does not add new constraints or detailed formatting rules beyond what the schema describes. With high schema coverage, this meets the baseline.

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 for claim verification against authoritative sources, with specific trigger phrases and a well-defined scope (company-financial claims for public US companies). It directly addresses the intended use case and distinguishes itself from generic lookup tools by describing its composite nature that replaces 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 gives explicit guidance on when to use the tool ('whenever the agent needs to check whether something a user said is factually correct'). It also mentions the domain limitation (v1 supports company-financial claims), but does not explicitly state when not to use it or provide alternatives for other claim types. This is a minor gap, but overall the usage context is clear.

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