The tool is a simple feedback submission with 3 parameters, all thoroughly documented in schema and extended by the description. No output schema is needed. The description covers all aspects: purpose, when to use, how to format, rate limits, and cost. Nothing is missing.

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 good descriptions, but the description adds substantial extra meaning: it explains when to use each type value, provides message formatting guidance ('Be specific', '1-2 sentences typical, 2000 chars max'), and clarifies the context field's usage.

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: 'Tell the Pipeworx team something is broken, missing, or needs to exist.' It enumerates specific use cases (bug, feature, data_gap, praise), and none of the sibling tools serve a similar feedback function, ensuring distinctiveness.

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: for wrong/stale data (bug), missing tool (feature/data_gap), or praise. It also provides do-nots ('don't paste the end-user's prompt') and formatting guidance ('describe in terms of Pipeworx tools/packs'). Rate limits and cost are also mentioned.

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, destructiveHint. Description adds caching behavior (5min-1h) and data derivation (CF analytics-engine, no PII). 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.

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 provide idempotent and non-destructive hints. The description adds key behaviors: OAuth requirement, delivery channel details, SMS cap, webhook auto-disable after 10 failures, and one-time webhook secret. 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 moderately long but well-structured with a clear lead sentence. Every sentence adds value, though some details could be slightly condensed without loss of 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?

Given the complexity of subscription types and delivery channels, the description covers prerequisites, constraints, return value, and edge cases (webhook failure, secret retrieval). No output schema, but the description adequately explains what is returned.

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 descriptions. The description adds significant context for type-specific parameters (e.g., sec_8k items, polymarket_edge topic) and delivery options (webhook signing, SMS verification), enriching 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 it creates a subscription to a live-data event stream and returns the new subscription ID. It distinguishes from siblings like list_subscriptions and unsubscribe by specifying the create action and supported 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?

The description specifies a prerequisite (Pipeworx OAuth account) and provides examples for different types. It could be more explicit about when not to use (e.g., for one-time data, use recent_alerts instead), but the context from sibling tools helps.

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 non-destructive. The description adds context that results are drawn from a live catalog of thousands of tools and can be called with no arguments or a topic, which is useful 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?

The description is somewhat long but well-structured with key phrases upfront. Every sentence adds value, listing categories and usage. Could be slightly more concise but is 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?

For a discovery tool with no output schema, the description thoroughly explains the output (category-bucketed example questions) and input. It covers all necessary context 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?

Schema coverage is 100% with a clear description. The description adds meaning by listing possible values and explaining that omitting the topic gives a full spread. This adds 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 states it is the onboarding entry point that returns category-bucketed example questions with exact tool+argument shapes. It clearly distinguishes from siblings like ask_pipeworx and discover_tools by focusing on getting started and generating ideas.

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 to use this FIRST when the agent does not know what Pipeworx can do or to learn how to call meta-tools. Also explains how to use the topic parameter. Lacks explicit when-not-to-use, but is clear enough.

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: ownership enforcement and deactivation (not deletion) are disclosed. Annotations already indicate mutation but description provides nuance.

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 purpose, no fluff.

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 parameter and no output schema, the description covers purpose, constraint, and behavioral detail adequately.

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 covers 100% of params. Description adds helpful context that the id is returned by subscribe, enhancing meaning beyond schema alone.

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 'Cancel' and the resource 'subscription by id'. It distinguishes 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?

Mentions ownership enforcement, implying it should only be used for own subscriptions. Could be improved by explicitly stating when not to use or suggesting to use list_subscriptions first.

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 valuable behavioral context: it explains the two processing paths (SEC XBRL fast path for financial claims, grounded fallback for others), details the return structure (verdict, value with citation, reasoning), and notes that it replaces 4-6 sequential calls. 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 front-loaded with trigger phrases and covers key aspects without being overly verbose. While it is longer than typical, every sentence adds value (trigger phrases, processing paths, return structure, efficiency claim). It is well-structured and easy to parse.

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 that there is no output schema, the description clearly explains the return values (verdict, value with citation, reasoning) and the processing logic. It covers the main use cases (financial and other claims). However, it could mention edge cases like ambiguous claims or source unavailability, but overall it is sufficient 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?

Schema coverage is 100%, but the description adds meaning beyond the schema: for 'claim', it provides example natural-language phrases; for 'tolerance_pct', it explains how to use it for hallucination detection and mentions the default behavior. This helps the agent understand parameter usage better than schema alone.

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. It provides specific trigger phrases ('Is it true that…', 'fact check', etc.), making it easy for the agent to recognize when to use this tool. The description distinguishes this tool from siblings by detailing its unique two-path processing (SEC EDGAR for financial claims, grounded pipeline for others).

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: 'Use whenever the agent needs to check whether something a user said is factually correct.' It gives examples of claim types (financial vs. other) and explains the different paths. However, it does not explicitly exclude alternatives like ask_pipeworx_grounded or provide when-not-to-use scenarios.

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