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 concise, fitting in two sentences with no redundant words. It effectively communicates the core functionality, parameters, and use cases. Minor improvement could be adding bullet points for readability, but it's well-structured as is.

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 complexity (4 parameters, read-only, no output schema), the description is complete. It covers what the tool does, what it returns, and how to configure it. The annotations provide safety information, so the description focuses on functionality and usage.

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 has 100% description coverage, but the description adds practical context: examples for `entity`, supported model values for `models`, the purpose of `_apiKey`, and disambiguation help for `context`. This adds meaning beyond the schema documentation.

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: probing LLMs for visibility of an entity and scoring it. It uses a specific verb ('probe') and resource ('LLMs for visibility').

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states it performs semantic search inside a fetched record, returns passages with offsets and similarity scores. Distinguishes from siblings by mentioning it pairs with ask_pipeworx_grounded.

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 when the record is too big to cram into the prompt' and describes how it saves context. Recommends pairing with ask_pipeworx_grounded for grounding over relevant passages.

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 fully explains the creation behavior, requirements (OAuth, phone verification), delivery channel nuances (feed always on, email/SMS/webhook with details on webhook signing and auto-disable after 10 failures), and does not contradict any annotation (readOnlyHint=false, idempotentHint=true, 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?

The description is well-structured and informative, but could be slightly more concise. However, every sentence adds necessary context, and it effectively front-loads the core purpose.

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 complexity (multiple types, nested params, delivery options), the description covers all essential aspects: action, types, params, delivery behavior, security, and limitations. No output schema exists, but the return value is stated.

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 extensive value by providing concrete examples for each subscription type and explaining each delivery field's format, requirements, and limitations (e.g., SMS 10/day cap, webhook HMAC signing).

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 lists supported types and delivery channels, distinguishing it clearly from sibling tools like list_subscriptions 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 provides clear context on when to use (proactive monitoring) and prerequisites (Pipeworx OAuth account, phone verification for SMS), but does not explicitly mention when not to use it or compare to alternatives like list_subscriptions or unsubscribe.

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, idempotentHint, and destructiveHint. Description adds that it draws from a live catalog and returns example questions with tool+argument shapes, which enhances understanding 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 examples and options. It is front-loaded with example queries. Every sentence provides useful information, though a minor reduction in length could improve 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?

Given the tool's simplicity (one optional parameter, no output schema) and rich annotations, the description covers purpose, usage, parameters, and output expectations. It is sufficiently complete for an agent to decide and invoke 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?

Schema coverage is 100% for the single optional parameter. Description adds value by listing possible topic values (finance, pharma, etc.) and explaining the effect of omitting the parameter, going beyond the schema's 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 provides a specific verb and resource: returns category-bucketed example questions for onboarding. It clearly distinguishes itself from siblings like ask_pipeworx or discover_tools by being the 'onboarding entry point' and includes explicit example queries.

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 advises 'Use this FIRST' when the agent does not know what Pipeworx can do, and mentions learning to call meta-tools. Could be stronger on when not to use it, but the guidance is clear and action-oriented.

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: it clarifies that the operation is not truly destructive by explaining 'deactivated (not deleted)' and that historical events remain. This aligns with destructiveHint=false and idempotentHint=true, with no 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?

Three sentences, each essential: action, ownership constraint, and behavioral effect. Front-loaded with verb 'Cancel' and resource. No redundant 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?

For a simple one-parameter tool without output schema, the description adequately explains the mutation semantics, ownership, and impact on historical data. No gaps given the tool's simplicity.

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 for the single parameter 'id'. The description does not add additional meaning beyond what the schema already provides, so baseline score 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 it cancels a subscription by id, with specific verb 'Cancel' and resource 'subscription'. It distinguishes itself from related 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?

The description explicitly mentions ownership enforcement and that only own subscriptions can be cancelled. It explains that the row is deactivated rather than deleted, providing clear context on when to use. However, it does not explicitly mention when not to use or provide direct 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, openWorldHint, idempotentHint, and non-destructive. The description adds rich behavioral context: internal routing logic (structured vs grounded), return format (verdict, value, citation, reasoning), and that it replaces 4-6 sequential calls. 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?

Description is front-loaded with key phrases and contains useful details, but is somewhat lengthy. Every sentence adds value, though minor redundancy exists (e.g., 'routed to the right live source'). Still, it's efficiently structured for agent consumption.

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 complexity (two processing paths, parameters), the description is thorough. It explains the return structure even without an output schema, and covers all necessary context for an agent to use it 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?

Schema coverage is 100% and description adds meaning beyond it: claim is natural-language, tolerance_pct overrides implied tolerance with default capped at 5. This helps agents understand parameter semantics beyond the 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 is for claim verification with natural-language examples. It distinguishes between company-financial claims (structured SEC path) and other claims (grounded pipeline), and the purpose is distinct from sibling tools like deep_research or ask_pipeworx_grounded.

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.' It explains the two internal paths but does not list specific exclusions or when not to use. Still, the context is clear and helps differentiate from siblings.

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