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

Annotations already indicate readOnly, idempotent, non-destructive behavior. The description adds value by detailing the return structure (per-model and combined view) and cost implications (free default, BYO key for Anthropic). 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?

Four sentences, each earning its place: purpose, default+optional key, return shape, use cases. Front-loaded with the core function. No unnecessary 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?

Given no output schema, the description sufficiently explains the return format. All parameters are covered, use cases are provided, and the tool's behavior is clear for its moderate 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%, baseline is 3. The description adds value with concrete examples for 'entity', lists supported models, explains the _apiKey purpose, and gives a disambiguation example for 'context'. This goes beyond the schema definitions.

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 probes LLMs for knowledge about an entity and scores visibility (0-100). It specifies the default model and optional Anthropic probe, distinguishing it from generic search or entity profile tools among siblings.

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 lists use cases (marketing audits, brand checks, competitive monitoring) and explains when to use the _apiKey for Anthropic. While it doesn't explicitly exclude alternatives, the context is clear enough for most scenarios.

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 the tool as read-only, open-world, idempotent, and non-destructive. The description adds valuable behavioral context: it fills arguments automatically, returns stable pipeworx:// citation URIs, works on every tier, and is a single fast call. It does not contradict 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 long but every sentence adds value: it front-loads the primary directive, lists supported domains, provides examples, and contrasts with alternatives. It is structured and readable, though slightly verbose, which is justified by the breadth of the tool.

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 (a router across thousands of sources), the description explains its core behavior, return type (structured answer with citations), performance characteristics, and relationship to sibling tools. It is complete enough for an agent to invoke correctly, though a mention of response format details would push it higher.

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 description coverage is 100% and the schema already defines the 'question' parameter with aliases. The description adds example queries (e.g., 'current US unemployment rate') but does not provide additional parameter-level semantics beyond what the schema offers. 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 states a clear, specific purpose: it routes factual questions to the appropriate tool among 5,462 verified sources and returns structured answers with citation URIs. It explicitly differentiates itself from web search and sibling tools like ask_pipeworx_grounded and deep_research, making its role unambiguous.

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?

Beyond readOnly/idempotent annotations, the description discloses beta status, identical behavior to stable, dynamic candidate routing changes, current no-active-candidate state, and that it falls back to nothing (full working router). This is rich behavioral context that annotations alone do not provide.

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 moderately long but every sentence adds value: identity, current state, usage guidance, and safety reassurance. Information is front-loaded with the beta/universal router summary first, then specifics.

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 an experimental variant of a known router, it provides complete context: what it is, how it relates to the stable version, current operational status, and that it behaves identically. No output schema is present, but 'same response shape' covers it by referencing the stable tool.

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 all aliases and question described. The description only says 'same arguments' without adding new semantic detail beyond schema, so it stays at the baseline for full schema coverage.

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 richly discloses behavior beyond annotations: it explains the refusal mechanism with specific refusal_reason values (not_in_source, no_tool_match, etc.), return shape, and the cost trade-off (one extra LLM call). This contextualizes the readOnlyHint and openWorldHint annotations. 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?

The description is dense but well-structured, front-loaded with the core purpose, then covering mechanics, return format, use cases, and trade-offs. It is longer than ideal but every sentence carries necessary information; a bulleted layout could improve scannability slightly.

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?

There is no output schema, so the description carries the full burden of explaining return values and refusal behavior, which it does comprehensively. It also addresses cost, when to use, and how it relates to sibling tools, making it complete for a high-stakes grounded query tool.

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 already fully describes the single required parameter ('question') and its aliases with 100% coverage. The description does not add additional parameter-specific meaning, so the baseline of 3 applies; the tool's argument is self-explanatory.

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?

Given the tool's complexity (3 params, nested object, enum, no output schema) and rich annotations, the description fully covers the context an agent needs: when to use, what to include, what to avoid, and server-specific scope. It leaves no critical gaps for successful invocation.

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 semantic guidance beyond schema: it clarifies how to describe the issue ('Describe the issue in terms of Pipeworx tools/packs') and reinforces the message field's purpose. This adds value over the schema's field-level 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 a specific verb and resource: 'Tell the Pipeworx team something is broken, missing, or needs to exist.' It distinguishes itself from sibling tools by framing this as a feedback channel, not a data query tool like ask_pipeworx or search.

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?

Explicit when-to-use guidance is given: 'Use when a tool returns wrong/stale data (bug), when a tool you wish existed isn't in the catalog (feature/data_gap), or when something worked surprisingly well (praise).' It also provides exclusions, telling users NOT to report issues for other MCP servers, and directs them to the correct alternative.

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 (6 parameters, no output schema), the description adequately covers return fields and optional text retrieval. It is sufficient for an agent to correctly invoke the tool.

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 the schema already documents all parameters. The description includes an example that reinforces usage but does not add new semantic information beyond what the schema 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 it performs neural/semantic web search, distinguishes from keyword search, and lists return fields. It differentiates from sibling tools like search_within by emphasizing meaning-based search.

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 a clear example and states the tool is for finding pages by meaning. It implicitly distinguishes from keyword search via the 'type' parameter, but does not explicitly state when not to use or list 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 indicate a safe, read-only operation; the description adds details about truncation at 200K chars, embedding model, windowing, and that passages include offsets and scores, going 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?

Dense single paragraph with no wasted words; purpose, usage, technical details, and pairing are efficiently front-loaded.

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, details like return format (passages with offsets and scores), limits, and embedding model provide full contextual coverage for an AI 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 covers all parameters, but description adds meaningful context: truncation for 'text', example queries for 'query', and default/range for 'limit', 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 the tool performs semantic search inside a fetched record, using examples like SEC 10-K and articles, and distinguishes it from other tools by emphasizing context-saving and pairings.

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 when to use (record too large for prompt) and offers an alternative (pair with ask_pipeworx_grounded), providing clear guidance.

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 behavioral details beyond annotations, such as the need for OAuth, SMS caps, and webhook signing. However, it does not explicitly confirm idempotency as hinted by 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 with clear sections, but is slightly lengthy; however, every sentence adds value given the tool's 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?

The description covers usage, types, delivery options, and constraints comprehensively, though it lacks explicit return structure beyond the subscription id.

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 significant value by providing concrete examples and constraints for type-specific params and delivery channels.

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 explicitly states the tool creates a proactive monitoring subscription to a live-data event stream, differentiating it from sibling tools like list_subscriptions and unsubscribe.

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 for when to use the tool (proactive monitoring) and notes the OAuth requirement, but does not explicitly mention alternatives or when not to use it.

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 that it returns category-bucketed example questions with tool+argument shape, drawn from a live catalog. No contradictions with annotations (readOnly, openWorld, idempotent, non-destructive). Adds rich 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?

Well-structured with clear sections, but slightly verbose. Could be trimmed without losing key info. Still, every sentence adds value and it is front-loaded with 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 simplicity (one optional param, no output schema), the description adequately explains output format and usage. No gaps for agent understanding.

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 description for topic. The description adds usage semantics: 'Call with no arguments for full spread, or pass topic to focus.' This provides more meaning than the 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 uses a specific verb (suggest questions) and identifies it as the onboarding entry point. It distinguishes from siblings by noting it returns 'exact tool + argument shape' and contrasts with meta-tools like ask_pipeworx.

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' and explains when to use with/without topic argument. Provides clear guidance on when to use this tool versus 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?

Beyond annotations that mark it as non-destructive, the description adds critical behavior: 'row is deactivated (not deleted) so its historical events stay available via recent_alerts.' This discloses the soft-delete nature, enhancing transparency.

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-load purpose and behavioral constraints. No wasted words; every sentence serves a clear 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?

For a simple one-parameter tool with no output schema, the description fully covers purpose, usage constraint, and behavioral outcome. Relationships to subscribe and recent_alerts are implied.

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 including parameter description, the tool description adds only 'by id' and ownership context. Baseline 3 is appropriate as schema already provides meaning.

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 uses specific verb 'Cancel' and resource 'subscription by id', clearly distinguishing this from sibling tools like subscribe and list_subscriptions. It reinforces the title with actionable detail.

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 ownership enforcement ('you can only cancel your own subscriptions'), providing clear context for when to use. However, it does not explicitly mention when not to use or compare with 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, idempotentHint, and non-destructive behavior. The description adds significant context: the two verification paths (fast SEC EDGAR vs grounded pipeline), the return structure (verdict, actual value with citation, reasoning), and that it uses 'exact percent-delta math' for financial claims. 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 relatively long but highly informative. It is front-loaded with the purpose and usage, then details the two pipelines and returns. Every sentence contributes value, though it could be slightly more concise. Overall, well-structured and 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?

Despite lacking an output schema, the description sufficiently explains the return values (verdict, actual value with citation, reasoning) and the two operational pipelines. It covers main use cases and efficiency benefits. Minor gaps remain (e.g., error handling for unsupported claims), but overall complete for a claim verification tool.

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 both parameters ('claim' and 'tolerance_pct') have clear descriptions in the schema. The description reinforces the tolerance_pct functionality (overrides default) but does not add new semantic information beyond what the schema already provides. Baseline score of 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 explicitly states 'natural-language claim verification against authoritative sources' and lists trigger phrases like 'Is it true that…' and 'fact check'. It distinguishes from sibling tools by detailing two distinct verification pipelines: a structured SEC EDGAR + XBRL fast path for company-financial claims and a grounded pipeline for all other factual claims.

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 clearly states 'Use whenever the agent needs to check whether something a user said is factually correct' and implies the tool is efficient by noting it 'replaces 4–6 sequential calls'. It does not provide explicit when-not-to-use scenarios, but the context of sibling tools and the description's focus on claim verification provides adequate guidance.

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