The description provides a concrete example with both required and optional parameters, helping the agent understand how to invoke the tool. However, it does not explicitly state when to avoid using this tool or suggest alternatives, which would have elevated the score.

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 technical details beyond annotations: uses BGE-base-en embeddings, cosine similarity, 500-char overlapping windows, 200K char cap with truncation and flagging. No contradiction with annotations (readOnly, idempotent, etc.).

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?

Efficient use of space: purpose, usage guidance, technical details, and pairing info all in a few sentences. Front-loaded with intent, no wasted 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?

Even without an output schema, the description explains return format (passages with offsets and scores) and limitations (200K char truncation). Complete for a search tool with comprehensive annotations.

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 description adds meaning: explains that 'text' is the pre-fetched content, 'query' is natural-language, and that results include offsets and scores. Goes beyond what schema alone provides.

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 verb 'search' and the resource 'inside a fetched record'. It provides concrete examples (SEC 10-K body, article) and distinguishes itself from siblings like 'ask_pipeworx_grounded' by explaining how they pair.

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 to use when records are too large for the prompt, saving context. Mentions pairing with 'ask_pipeworx_grounded'. Does not explicitly exclude any use cases, 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?

The description explains the subscription creation behavior, return value, and delivery channel specifics. However, the idempotentHint annotation suggests idempotency, which contradicts the creation of multiple subscriptions with repeated calls. This is flagged as an annotation contradiction.

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 the core purpose, but it is somewhat dense with many details. All sentences are informative, though conciseness could be improved by grouping related info.

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 covers the tool's purpose, parameters, return value, delivery channels, requirements, and quirks (e.g., webhook signing, auto-disable). No output schema exists, but the description adequately explains the response.

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, the description adds substantial value by providing concrete examples for each subscription type, explaining required fields like items for sec_8k, and detailing delivery constraints such as phone verification and SMS caps.

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 a subscription ID. It distinguishes itself from sibling tools like list_subscriptions and unsubscribe 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?

The description provides context on when to use the tool and mentions prerequisites (Pipeworx OAuth account, phone verification for SMS). It does not explicitly state when not to use it or compare to alternatives, but 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.

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

Annotations already indicate readOnlyHint=true, openWorldHint=true, idempotentHint=true, destructiveHint=false. Description adds that it returns category-bucketed examples and can be called with no arguments or a focused topic, providing 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 information-rich but front-loaded: purpose and usage guidance first, then categories. Every sentence adds value, though could be slightly shorter 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?

With one optional parameter and no output schema, the description fully covers purpose, usage, parameter details, and expected output structure. No gaps remain for a new 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% with one optional parameter. Description explicitly lists the acceptable topic values (finance, pharma, etc.) and explains behavior when omitted, adding significant meaning beyond 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 it is an onboarding entry point that returns category-bucketed example questions, using specific verbs like 'returns' and listing categories. It distinguishes from siblings as the only tool for suggesting initial questions.

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 says 'Use this FIRST when you do not yet know what Pipeworx can do for you'. Provides guidance on optional topic parameter, but lacks explicit when-not-to-use or exclusion criteria.

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 significant behavioral context beyond annotations: ownership enforcement, deactivation instead of deletion, and preservation of historical events. Annotations already indicate non-destructive (destructiveHint=false) and idempotent (idempotentHint=true), and the description aligns with and enriches these.

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, front-loaded with the core action. Every sentence serves a purpose: first states what it does, second explains behavioral nuances. No wasted 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 single-parameter tool with no output schema, the description fully covers purpose, ownership, outcome (deactivation), and side effects (historical events preserved). Annotations and schema are rich enough, and the description completes the picture.

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 sole parameter 'id' is fully described in the schema (100% coverage). The description adds the ownership constraint ('you can only cancel your own subscriptions'), which provides contextual meaning beyond the schema's type and 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 action ('Cancel a subscription by id'), identifies the resource ('subscription'), and distinguishes from sibling tools like 'subscribe' and 'list_subscriptions' through ownership enforcement and deactivation behavior.

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 clear context: ownership enforcement means only your own subscriptions can be canceled, and it mentions that the row is deactivated (not deleted) with historical events remaining accessible via recent_alerts. While alternatives aren't explicitly named, the implied usage is well-defined.

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 (readOnlyHint, openWorldHint, idempotentHint, destructiveHint) by explaining the processing flow: financial claims via SEC EDGAR with exact math, other claims via grounded pipeline. It also mentions the return verdict types and citation format. 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 a single dense paragraph that conveys all key information without redundancy. It could be slightly improved by using bullet points or clearer separation of the two paths, but it remains concise and front-loads the purpose effectively.

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?

Despite no output schema, the description fully specifies the return format (verdict, actual value with citation, reasoning) and explains the two processing paths. This provides a complete mental model for using the tool correctly.

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 description enriches the parameters significantly. For 'tolerance_pct', it explains the range, intent (hallucination detection), and default behavior. For 'claim', it provides natural-language examples. Since schema coverage is 100%, this extra context is valuable and goes beyond the basic 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 as 'natural-language claim verification against authoritative sources' and provides concrete examples of user queries. It distinguishes between two processing paths (SEC EDGAR for financial claims, grounded pipeline for others), making it unique among sibling tools like ask_pipeworx_grounded or deep_research.

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 details the two internal paths. However, it does not explicitly state when not to use this tool or mention alternatives, though the sibling list provides context.

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