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

The annotations already provide readOnlyHint, openWorldHint, etc. The description adds valuable behavioral details: probes multiple LLMs, scores on a 0-100 scale, default model is free, Anthropic requires BYO key and direct payment, and the return structure includes per-model fields and a combined view. 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 four sentences, front-loaded with the main action, and each sentence adds necessary information without redundancy. Perfectly concise and well-structured.

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 (4 parameters, 1 required, no enums, no output schema), the description covers purpose, usage, parameter details, and return format. It is sufficiently complete for an agent to determine when and how to 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 description coverage is 100%, so baseline is 3. The description adds context beyond the schema: explains that 'models' must include 'anthropic' for the _apiKey to be used, and that you pay Anthropic directly. This enhances understanding for the agent.

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 returns a visibility score (0-100) per model. It distinguishes itself from siblings like 'ask_pipeworx' or 'scan_competitor_ai_presence' by focusing on 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?

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 goes far beyond the annotations (readOnlyHint, idempotentHint, etc.) by detailing internal mechanisms: classifier types, fan-out examples, response shapes (e.g., result.market fields, result.analysis with model probability and edge), resolver contract with confidence levels, parent event extractor, news fallback handling, safety for low-confidence matches, closed market behavior, wide-spread tradeability warnings, and cancellation rule risk. This level of disclosure is exceptional.

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 quite long but well-structured, using headers (CLASSIFIERS, FAN-OUT EXAMPLES, RESPONSE SHAPES, etc.) to organize information. It front-loads the core purpose and usage, then provides detailed sections. While every sentence serves a purpose, some redundancy (e.g., repeating the input formats) could be trimmed. Overall, it balances comprehensiveness with readability.

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 fully explains the return shape: result.market with fields like best_bid, best_ask, spread_pp; result.analysis with model probability, edge, and 24h-move warning; result.evidence keyed by source; resolver contract with confidence levels; parent event extractor; and error/edge-case handling (low confidence, closed markets, wide spreads, cancellation rules). It covers all expected behaviors and outputs, leaving no critical gaps.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already describes all three parameters (market, depth, include_raw) with 100% coverage, but the tool description adds valuable context: it explains that market accepts slugs, URLs, or question text; it specifies the default for depth ('thorough'); and it clarifies what include_raw does and the size implications. This extra information helps agents make informed choices.

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: 'Research a Polymarket bet by pulling the relevant Pipeworx data for it in one call.' It specifies the verb (research), resource (Polymarket bet), and the method (pull data). It also explicitly states use cases: 'Use for "should I bet on X", "what does the data say about Y", or "is there edge in Z".' This differentiates it from sibling tools like polymarket_edges, which focus on edge tracking.

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?

No guidance on when to use this tool versus alternatives (e.g., get_track, get_artist). The agent must infer usage solely from the tool name and listed features.

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, idempotentHint, and destructiveHint, so the description's job is light. The description adds the specific fields returned, but does not disclose any additional behavioral traits like rate limits or authorization requirements.

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 long and front-loads the core purpose. Every word is necessary; no filler or redundancy.

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 is complete for a simple retrieval tool. Given the full schema coverage and presence of an output schema, it adequately informs the agent of what the tool does and returns.

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 parameters are fully documented in the schema. The description does not add extra meaning beyond the schema, but it connects parameters to the output by naming returned fields.

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 retrieves a single track by Spotify ID and lists the returned fields (artists, album, popularity, preview URL, duration). It distinguishes itself from sibling tools like get_album or get_artist.

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?

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

Annotations are all false (readOnlyHint, destructiveHint, etc.), providing minimal behavioral data. The description adds valuable context: rate-limited to 5 per identifier per day, free, doesn't count against tool-call quota, and appropriate feedback types. It doesn't disclose side effects or data persistence, but for a feedback tool, this is sufficient. 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 highly concise with no wasted words. It front-loads the core action ('Tell the Pipeworx team...'), then efficiently lists use cases, formatting rules, and limitations. Every sentence earns its place.

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 (sending feedback), the description covers the necessary aspects: what to use, how to format, rate limits, and quota. There is no output schema, but the description explains that it's free and doesn't count against quota. It doesn't mention confirmation or response, but for a feedback tool, it is adequately complete.

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 each parameter described. The description adds value beyond schema by specifying message format (1-2 sentences, 2000 chars max) and elaborating on the 'type' enum. It also gives guidance on the optional 'context' object fields. This enhances the schema's 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 clearly states the tool's purpose: sending feedback to the Pipeworx team about bugs, missing features, data gaps, or praise. It uses specific verbs and resources ('tell the Pipeworx team') and distinguishes itself from sibling tools by being a feedback mechanism rather than a query or action tool.

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?

Three sentences: first sentence states the core purpose, second explains the mechanics, third provides a concrete use case. Every sentence is essential and front-loaded. No redundancy.

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 adequately describes the return format (ranked list with metrics). It mentions key parameters and the underlying tool. Minor missing details like error handling or entity count limits (though present in schema) but overall sufficient for an 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 description coverage is 100%, so the baseline is 3. The description adds value by explaining that the first entity in the array is treated as subject for narrative and that the output includes score, confidence, signal density. It also indirectly hints at models and context parameters through the use case.

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 compares AI visibility across multiple entities side-by-side, specifying it probes each entity with ai_visibility_check, ranks by score, and surfaces most/least recognized. This distinguishes it from sibling tools like ai_visibility_check (single probe) and compare_entities (generic comparison).

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 concrete use case ('competitive AI-marketing audits') and an example question. While it implies when to use, it does not explicitly exclude alternative tools or state when not to use. However, the example is clear and context-rich.

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, open-world, idempotent, non-destructive. The description adds significant behavioral details: fans out to sources, partial failures degrade gracefully, bundlephobia measurement timing (5-30s), and lists the 'sources_failed' field. 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 longer but well-structured: purpose, usage, return summary, limitations, partial behavior. Every sentence adds value; it is not overly verbose. Slightly long but justified 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?

Given the tool's complexity (multiple sources, composite check), the description covers purpose, usage, behavioral traits, limitations, and return fields. No output schema exists, but the description explicitly lists the summary block fields. Fully complete for its 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% with both parameters described. The description adds some context (scoped packages accepted, version defaults to latest), but this is already in the schema descriptions. Baseline 3 is appropriate; description provides minimal additive value.

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 a composite check for adding an npm package, specifying what it checks (deps.dev and bundlephobia) and the problem it solves. It distinguishes itself from siblings as no other tool offers this composite analysis.

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 provides usage guidance: 'Use whenever an agent asks...', gives example queries, and notes limitations (NPM only in v1, partial failures). It also mentions alternatives for other ecosystems, fulfilling all 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?

Annotations already indicate readOnlyHint, idempotentHint, destructiveHint. Description adds that results are in 'named sections,' which is helpful but minimal. No additional behavioral details 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?

Two sentences, front-loaded with purpose. Every piece of information is relevant and efficiently conveyed.

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 output schema exists, description need not detail return values. It covers core usage and result structure (named sections), making it sufficiently complete for a search 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 5 parameters. The description adds the default type ('track') and result format ('named sections'), which provides marginal extra meaning 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?

Description clearly states 'Search the Spotify catalog' and lists the searchable types (album, artist, etc.), which is specific and distinguishes it from sibling tools like search_within.

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?

Provides context on type parameter and defaults but does not explicitly state when to use versus alternatives, though the purpose 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 read-only and idempotent. Description adds crucial behavioral info: truncation at 200K chars, embedding model, window size, offset return, and truncation flag. Significantly enhances agent understanding.

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 purpose, then usage, then technical details. Every sentence adds value. No redundancy.

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, description details return values (passages, offsets, scores) and limitations (truncation). Perfectly adequate for 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 already has 100% coverage. Description adds value with examples for 'query' and clarifies 'limit' default range. Exceeds baseline expectations for coverage.

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?

Title and description clearly state the tool performs semantic search inside a fetched record. It distinguishes itself from siblings like 'search' and 'ask_pipeworx_grounded' by specifying it's for large records that don't fit in the prompt.

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 (when record is too big for prompt) and mentions pairing with ask_pipeworx_grounded. Implicitly indicates when not to use (small records). Provides clear 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?

The description adds substantial behavioral context beyond annotations: account prerequisites, delivery channel constraints (SMS cap, phone verification), webhook auto-disable after failures, and the fact that webhook secret is returned once. These details align with annotations (no contradictions) and greatly aid agent understanding.

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 packs a lot of information efficiently. It is front-loaded with the main purpose. While it could be broken into sections for readability, it remains concise given the complexity 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 (3 parameters, nested objects, multiple types and delivery channels), the description covers all essential aspects: purpose, prerequisites, type-specific parameters, delivery options with limits, and return value. No output schema exists, so the description appropriately handles the needed completeness.

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 significant meaning: for each type (e.g., sec_8k with items codes), it gives concrete examples and explains delivery channel specifics (feed always on, email/SMS/webhook constraints). This goes well 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 identifies the verb 'Create' and the resource 'proactive monitoring subscription', and specifies it returns the new subscription id. It distinguishes from sibling tools like 'unsubscribe' and 'list_subscriptions' by focusing on creation. Examples of supported types further clarify the tool's scope.

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 the prerequisite ('Requires a Pipeworx OAuth account') and provides detailed guidance on each subscription type with parameter examples. It does not explicitly state when not to use this tool versus alternatives, but the context and sibling tools make it reasonably 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 declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint. The description adds valuable context: it returns examples with exact tool + argument shape from a live catalog, and explains behavior with no arguments vs. topic. 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 fairly long but packed with useful information. It front-loads the purpose and usage. It could be slightly more concise, but for an onboarding tool, the length is justified. No wasted 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?

Given the tool's role as an onboarding entry point, the description is comprehensive. It explains what it returns, how to use it, and when to use it. No output schema exists, but that's acceptable as the results are examples.

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. The description adds meaning by explaining that omitting the parameter gives a full spread and providing a list of example topics. This supplements the schema's enum 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 tool as an onboarding entry point for an agent that just connected, returning category-bucketed example questions. It distinguishes itself from siblings by being the first tool to use when unsure what Pipeworx can do. The verb 'suggest questions' is well supported.

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 'Use this FIRST when you do not yet know what Pipeworx can do for you' and provides guidance on calling with no arguments for full spread or passing a topic to focus. It also references meta-tools as alternatives for learning how to call them.

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 non-destructive and idempotent. The description adds valuable context: the row is deactivated not deleted, and historical events remain available. 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?

Two sentences, front-loaded with purpose and ownership, then deactivation detail. 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?

For a simple one-parameter tool with annotations and no output schema, the description covers purpose, ownership, deletion behavior, and relation to recent_alerts. Complete and sufficient.

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 only reiterates that the id is returned by subscribe. No additional meaning beyond what the schema already 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 'Cancel a subscription by id' with a specific verb and resource. It distinguishes from sibling tools like 'subscribe' and 'list_subscriptions' by mentioning 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?

Provides clear context: ownership is enforced so you can only cancel your own subscriptions. It hints at alternative 'recent_alerts' for viewing historical events. No explicit exclusion statements, but enough for correct usage.

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=true, openWorldHint=true, idempotentHint=true, destructiveHint=false. The description adds context about using SEC EDGAR + XBRL, returning specific verdicts, and citation format. It also explains performance benefits. 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 somewhat lengthy but front-loaded with examples and usage triggers. It is well-structured with clear sections (examples, usage, domain, return values, efficiency). Every sentence contributes meaningful 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 tool with one simple parameter and rich annotations, the description covers purpose, usage, domain, return format, and performance benefit. It is fully complete given the tool's complexity and available structured metadata.

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?

Only one parameter 'claim' with 100% schema description coverage. The description adds value with examples and clarification of expected format ('Natural-language factual claim'), enriching the bare schema definition.

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 starts with natural-language examples ('Is it true that...?', 'fact check') and clearly states the tool's purpose: claim verification against authoritative sources. It specifies the domain (company-financial claims for public US companies) and distinguishes from siblings by noting it replaces 4-6 sequential calls.

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 'Use whenever the agent needs to check whether something a user said is factually correct.' The domain limitation ('company-financial claims') implicitly tells when not to use. However, it lacks explicit alternatives or when-not scenarios.

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