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

Annotations indicate read-only, idempotent, non-destructive behavior. The description adds that it probes LLMs, returns per-model scores, and explains the default model and optional Anthropic usage with BYO key. It does not contradict annotations and provides valuable 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 two sentences: first summarizes the core function, second provides usage details. Every sentence serves a purpose with no redundancy. It is front-loaded and appropriately sized.

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 explains the return structure (per-model score, confidence, signals, raw_response + combined view). The required parameter, optional parameters, and their purposes are all covered. The tool is complex but the description fully addresses its 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 description coverage is 100%, so baseline is 3. The tool description adds value by explaining the default model, the role of the API key (BYO key, pay directly), and the context parameter's purpose for disambiguation. This extra information warrants a 4.

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 'probe', the resource 'LLMs for knowledge about an entity', and the output 'score visibility (0-100) per model'. It distinguishes itself from siblings like 'scan_competitor_ai_presence' by focusing on general AI visibility scoring across multiple models.

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 explicit guidance on when to use (AI-marketing audits, pre-launch brand checks, competitive monitoring) and how to customize (default free model, optional Anthropic with API key). It lacks explicit when-not-to-use or direct comparison with alternatives, 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 already cover readOnly, openWorld, idempotent, non-destructive. The description adds valuable context about routing to 5,008 tools, filling arguments, returning structured answers with citation URIs.

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 fairly long but well-structured with front-loaded key message, bullet-like usage guidance, and examples. A minor reduction in length could improve conciseness without losing content.

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?

Covers purpose, usage guidelines, behavioral traits, parameter aliases, and return format (structured answer with citation URIs). No output schema exists, but description suffices for a query tool with good 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 clearly describes the 'question' parameter. The description adds that aliases (query, q, prompt, etc.) are accepted, providing incremental value but not exceeding 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 specifies a clear verb ('ask'), resource ('Pipeworx'), and scope ('current or historical data') with a broad list of domains. It distinguishes from siblings like ask_pipeworx_grounded and deep_research by specifying when to use each.

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 'PREFER OVER WEB SEARCH' and provides clear directives: 'START HERE for most questions' and 'Step up only when needed' with specific alternatives for different use cases.

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 behavioral traits beyond the annotations: it is a full working router with fallback to nothing, source-preference ranking, and identical arguments/response shape to ask_pipeworx. Annotations already indicate read-only, open-world, idempotent, non-destructive; the description adds rich behavioral context about routing logic and experimental nature.

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 about 130 words, which is somewhat long but necessary to explain the beta router's behavior. It front-loads the key point ('Beta version of ask_pipeworx') and provides structured detail about ranking and usage. Could be slightly more concise, but 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 complexity (router with 5,008 tools, experimental), the description covers purpose, usage, relationship to sibling, and behavioral traits. It lacks explicit return value shape, but since output schema is not provided and the description mentions 'same response shape' as ask_pipeworx, it is sufficiently complete for a beta 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 description coverage is 100% (all parameters documented in schema). The description does not add meaning beyond the schema; it only mentions 'same arguments' as ask_pipeworx. Baseline of 3 is appropriate because no additional parameter semantics are provided.

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 a beta version of ask_pipeworx, a universal router with 5,008 tools. It distinguishes itself from the stable ask_pipeworx by noting candidate routing improvements and specifically source-preference ranking. The verb 'ask' and resource 'pipeworx' are clearly identified, and it differentiates from the sibling tool 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?

The description explicitly states to use it 'exactly like ask_pipeworx when you want the newest routing' and mentions results are compared against the stable router. It provides clear context for when to use (experimental edge) but does not explicitly state when not to use (e.g., for production stability). Still, the guidance is clear and helpful.

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?

Transparently describes internal routing across 5,008 tools, argument filling, data fetching, and extraction of answer using only tool result. Details return fields and explicit refusal reasons. Consistent with readOnlyHint and idempotentHint 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?

Front-loaded with purpose and ends with usage guidance. Slightly verbose but well-structured; each sentence adds value. Could be tightened 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?

Covers return format including evidence and refusal reasons. Lacks output schema but description compensates. Would benefit from mentioning error handling beyond refusals, but overall adequate for complex 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 descriptions for all aliases. Description adds minimal extra meaning beyond stating it is a natural language question for high-stakes reads, but does not significantly enhance understanding 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?

Clearly states it is a 'hallucination-resistant answer mode' that extracts answers exclusively from tool results. Distinguishes from sibling 'ask_pipeworx' by noting it costs an extra LLM call and is for high-stakes reads.

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 whenever an answer will be quoted, cited, or acted on' and lists examples (financial verdicts, legal claims). Also advises to 'prefer ask_pipeworx for casual lookups,' providing clear when-not-to-use 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 extensively details behavioral traits beyond annotations: classifier categories, fan-out examples, response shapes (market, analysis, evidence), resolver contract, parent event extractor, news fields with fallback info, safety mechanisms for low-confidence matches, closed markets, wide spreads, and resolution-rule risk. Annotations already indicate readOnlyHint=true, and the description aligns perfectly while adding rich context.

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-dense and front-loads the purpose, but it is quite lengthy. Every sentence adds value, but the length could be reduced without losing essential guidance. It is adequately structured but not concise enough for a top score.

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 classifiers, fan-out patterns, resolver, parent event, news fields, safety cases, and resolution rules), the description is remarkably complete. It covers return structure even without an output schema, explaining evidence packet composition and edge cases. Nothing essential is omitted.

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% (all three parameters have descriptions in the input schema). The description adds examples and context (e.g., types of market inputs) but does not provide additional meaning beyond the schema's parameter descriptions. The baseline is 3, and no extra semantic value is added.

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: researching a Polymarket bet by pulling Pipeworx data. It specifies input types (slug, URL, question) and the process (resolves market, classifies, fans out). However, it does not explicitly distinguish from sibling tools like polymarket_arbitrage or polymarket_edges, so it misses the sibling differentiation criterion for a 5.

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 explicit use cases: 'Use for "should I bet on X", "what does the data say about Y", or "is there edge in Z".' This gives clear context for when to invoke the tool. It does not mention when NOT to use it or name alternatives, but the usage guidance is clear and practical.

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?

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 fairly concise given the amount of information conveyed, starting with examples and proceeding to details. However, it could be improved with better structure (e.g., bullet points) for easier parsing. No superfluous sentences.

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 explains that the tool returns 'paired data + pipeworx:// citation URIs per entity.' It covers both entity types adequately, and the annotations already address safety and idempotency. Some missing detail on return structure, but still sufficient for agent use.

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% coverage with descriptions for both parameters (type and values). The description adds value by explaining the return data for each type (financial data for companies, adverse events for drugs) and hinting at sorting behavior, which goes 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 clearly states the tool performs side-by-side comparison of 2-5 entities (companies or drugs) and specifies the data sources (SEC EDGAR, FAERS).

Description adds embedding model (BGE-base-en), similarity metric (cosine), window size (500-char overlapping), character cap (200K with truncation flag), and return format (passages with offsets and scores). 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 dense sentences front-loaded with purpose. Every sentence adds value: what it does, when to use, how it works, return details. 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?

No output schema, but description covers return values (passages with offsets and similarity scores), pairing with sibling, and behavior on truncation. Provides complete guidance for a retrieval 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 descriptions for text, query, and limit. The description adds context: text as 'document text', query with natural-language examples, limit as max passages. Also explains mechanics (overlapping windows) enhancing semantics beyond 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 performs 'semantic search INSIDE a fetched record', specifying the verb 'search' and the resource 'fetched record'. It distinguishes itself from siblings like ask_pipeworx_grounded by explaining the pairing and contrasting with fetching tools.

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 implies not to use for fetching. Provides alternative pairing with ask_pipeworx_grounded for grounding.

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 mutability, idempotency, and non-destructiveness. The description adds crucial details: returns subscription id, delivery limitations (SMS cap, webhook auto-disable after 10 failures), and signing secret info. 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 thorough but somewhat lengthy. It front-loads the main purpose and uses bullet points in a structured way, though a bit verbose.

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?

No output schema, but the description states 'Returns the new subscription id'. It covers prerequisites, types, delivery channels, and limitations, making it fully informative.

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 meaning by providing concrete examples for each type and delivery option, making the tool easier to use.

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 'Create a proactive monitoring subscription to a live-data event stream' and distinguishes it from sibling tools like 'unsubscribe' 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?

It specifies when to use (need to subscribe) and prerequisites (Pipeworx OAuth account), but doesn't explicitly mention when not to use or compare with alternatives like 'recent_alerts'.

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 false. The description adds that it returns category-bucketed example questions from a live catalog and accepts optional topic filtering. 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 front-loaded with trigger phrases and provides all necessary information in a structured manner. Slightly verbose but 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 onboarding purpose and lack of output schema, the description covers purpose, usage, behavior, parameter details, and context. It is sufficiently complete for an agent to use 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%, but the description adds meaning by specifying the optional nature of topic, listing allowed values (finance, pharma, etc.), and explaining the effect of omission (cross-category spread).

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 onboarding, answering 'what can I ask?' with example questions and tool+argument shapes. It distinguishes from discover_tools by focusing on question suggestions rather than tool listing.

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 suggests using this tool FIRST when unsure of Pipeworx capabilities. Mentions optional topic parameter for focus. Does not list explicit exclusions or alternatives but provides clear context.

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 read-only, idempotent, non-destructive behavior. The description adds value by clarifying the return values (translated text and detected source), which is beyond the structured 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 two sentences, front-loaded with the main verb, and every word adds value. No unnecessary 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?

With an output schema and 100% parameter description coverage, the description covers the essential behavior. However, it omits mention of the 'format' parameter, which is present in the schema and examples, leaving a minor gap.

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 mentions the 'auto' value for source, which is already in the schema's description for source. No additional semantics are provided 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 clearly states 'Translate text' as the core action, and adds useful details like auto-detection and return values. While it distinguishes the tool's purpose, it does not explicitly differentiate from sibling tools like detect_language.

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 (e.g., detect_language). It only states the function, leaving the agent without context for choosing among siblings.

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 the row is deactivated (not deleted) and that historical events remain accessible via recent_alerts. This adds valuable context beyond annotations (readOnlyHint, destructiveHint, idempotentHint), fully informing the agent of the tool's behavior.

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 redundant information, front-loaded with the core action and key constraint. 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 simplicity (one required param, no output schema), the description covers the essential behavioral details (ownership, deactivation, historical impact). Nothing important 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 description coverage is 100% and the parameter 'id' is well-documented in the schema. The description does not add additional semantic information beyond what the schema provides, meeting the baseline expectation.

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?

Clearly states the action ('Cancel a subscription by id') and resource (subscription). Differentiates from siblings like 'subscribe' and 'list_subscriptions' by emphasizing 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?

Explicitly states ownership constraint ('you can only cancel your own subscriptions'), indicating when the tool is applicable. Does not mention alternatives or exclusions beyond ownership, 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 aligns with annotations (readOnlyHint, openWorldHint, idempotentHint, destructiveHint false) and adds behavioral details: two pipeline routes, exact percent-delta math for financial claims, grounded pipeline for others, and returns verdict with citations. 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?

Single paragraph, front-loaded with trigger phrases. Every sentence adds value, though structure could be more concise or bulleted. Length is reasonable given 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?

Despite no output schema, the description covers return format (verdict, actual value, citation, reasoning). Parameters are fully explained, and the tool's logic (two pipelines, fallback) is clearly described. Sufficient for effective use.

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 both parameters well-described. The description adds meaningful context: claim examples, tolerance_pct default and use case (hallucination detection), and default cap. Goes beyond 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 provides specific trigger phrases like 'Is it true that…' and 'fact check', clearly states it verifies natural-language claims against authoritative sources, and distinguishes from siblings by noting it replaces 4-6 sequential calls and handles both company-financial and other 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 explicitly says 'Use whenever the agent needs to check whether something a user said is factually correct.' It differentiates between company-financial claims (fast path) and other claims (grounded pipeline). However, it does not provide explicit when-not-to-use guidance or name alternative tools.

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