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 value by explaining the tool's behavior: it probes multiple LLMs, scores visibility, and returns per-model data. It also clarifies pricing (free vs BYO) and does not contradict annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise (three sentences) and well-structured: it starts with core purpose, then specific details (default model, key usage), and ends with use cases. 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?

Given the tool has 4 parameters, no output schema, and annotations covering safety, the description provides sufficient completeness. It explains all parameter usage, return structure, and typical use cases. Could mention error handling but not essential.

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 meaning beyond the schema by explaining the default model, that `_apiKey` is for Anthropic and passed directly, and that 'context' helps disambiguate. This extra context justifies 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 tool's purpose: probing LLMs for knowledge about an entity and scoring visibility per model. It uses specific verbs ('probe', 'score') and resource ('LLMs', 'visibility'). It distinguishes from sibling tools like ask_pipeworx (general Q&A) and scan_competitor_ai_presence by focusing on scored visibility 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 clear use cases ('AI-marketing audits, pre-launch brand checks, competitive monitoring') and explains when to provide certain parameters (e.g., `_apiKey` for Anthropic). However, it does not explicitly contrast with sibling tools or specify when not to use this tool.

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 the annotations (readOnlyHint, openWorldHint, idempotentHint, non-destructive), the description adds valuable behavioral context: it routes questions to one of 5,564 tools across 1462 sources, fills arguments, returns structured answers with stable citation URIs. This clarifies the internal routing mechanism and output format, which is not visible in the schema or 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 detailed but well-structured: it starts with a clear directive ('PREFER OVER WEB SEARCH'), lists use cases, provides examples, and then gives sibling tool guidance. It is front-loaded with the most important takeaway. It is slightly long but each sentence earns its place, and there is minimal 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 this is a complex routing tool with 6 parameter aliases, no output schema, and many sibling tools, the description provides a very complete picture. It explains when to use it, its internal capabilities, its output format (structured with URIs), and clear decision points for alternative tools. The examples further reduce ambiguity. There is no output schema, but the description compensates by describing the return style.

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 coverage is 100%, so baseline is 3. The description mentions that the tool accepts a natural language question, but doesn't add additional meaning beyond what the schema already says (e.g., alias handling, that question is required). It does not explain parameter constraints, formatting, or language hints. It is adequate but not adding extra 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 is for answering factual questions about real-world entities, events, or numbers by routing to a large set of authoritative sources. It lists many example use cases (SEC filings, FDA data, weather, news, etc.) and explicitly distinguishes itself from web search by citing its internal citation system.

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 this tool, including a strong preference over web search for most factual queries. It also tells when to use alternatives like ask_pipeworx_grounded and deep_research, and even provides examples of when those alternatives are more appropriate (hallucination-resistant answers or broad multi-part questions).

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 annotations already declare readOnlyHint, openWorldHint, idempotentHint, and no destructiveness, so the safety profile is well covered. The description adds valuable behavioral context: it falls back to nothing (full working router), and though it's experimental, it is a fully functional router. The 'Beta' label and reference to 'candidate routing improvements' provide transparency about its reliability and purpose. 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 concise at about 70 words, front-loading the essential purpose and disclaiming the beta nature and current inactive state. Every sentence contributes useful context, though the list of aliases is better suited to the schema, preventing a perfect 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?

The description is fully self-contained for a routing tool with rich annotations and 100% schema coverage. It explains the beta status, current equivalence to the stable tool, and experimental purpose without needing an output schema or additional details about return values.

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%, with the 'question' parameter well described as accepting natural language with multiple aliases. The description does not add additional parameter meaning beyond what the schema already provides, so a baseline 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 clearly states it is a 'beta version of ask_pipeworx' that serves as an 'identical universal router' with the same 5,564 tools and response shape. It distinguishes itself from the stable siblings by highlighting its experimental nature and use for testing routing improvements.

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 to 'use it exactly like ask_pipeworx' when wanting the newest routing, and explains that results are compared against the stable router to decide merges. It also clarifies that no candidate is currently active, so it currently matches the stable version, providing clear when-to-use guidance relative to alternatives.

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

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint as false. The description adds significant behavioral context: it makes one extra LLM call, returns explicit refusal reasons (not_in_source, no_tool_match, etc.), and extracts the answer only from the tool result (hallucination-resistant). It also details the return structure, including evidence, confidence, and refusal_reason, which is information beyond what annotations 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?

The description is a single paragraph that front-loads the core purpose. It is reasonably concise, though the return structure details could be slightly more terse. Every sentence serves a purpose (purpose, usage, behavior, cost trade-off), and no unnecessary filler is present. It earns a 4 for being efficient but not maximally lean.

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 has no output schema, the description compensates by fully describing the return format, possible refusal reasons, and the hallucination-resistant property. It also explains the cost trade-off and how the tool resolves queries. The sibling list is large, but the description effectively differentiates this tool from ask_pipeworx. For a high-stakes answer tool, this is complete and actionable.

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% with all parameters described. The description mentions 'Your question in natural language' and lists aliases, but this adds no new semantic meaning beyond what the input schema already provides. Per the guidelines, with high coverage, baseline is 3, and the description does not compensate further.

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 a 'Hallucination-resistant answer mode for high-stakes reads.' It explicitly describes the process: picks the right tool from 5,564 across 1462 sources, fetches data, and extracts the answer using only the tool result. It distinguishes from the sibling ask_pipeworx by specifying the grounded extraction step, making the purpose unambiguous.

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 when-to-use guidance: 'Use whenever an answer will be quoted, cited, or acted on, and the agent must not invent facts (financial verdicts, legal claims, medical lookups, public statements).' It also gives a clear alternative preference: 'Costs one extra LLM call vs ask_pipeworx — prefer ask_pipeworx for casual lookups.' This effectively tells the agent when to choose this tool over its sibling.

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 extensive behavioral details beyond annotations: resolver contract (match confidence, alternatives), parent_event extractor, news fields with fallbacks, safety mechanisms (low-confidence short-circuiting, closed markets), wide-spread handling, and resolution-rule risk parsing. No contradictions with annotations (readOnly, openWorld, idempotent, non-destructive).

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 well-structured with labeled sections (CLASSIFIERS, FAN-OUT EXAMPLES, RESPONSE SHAPES, etc.). Every sentence provides useful information. Minor improvement: could reduce some redundancy (e.g., repeated mention of low_confidence_match).

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 params, no output schema), the description covers resolution logic, edge cases, fallbacks, and safety mechanisms thoroughly. It explains response shapes, making up for missing output schema.

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 value by explaining the flexible input format for 'market', default depth behavior, and when to set 'include_raw' to true (detailed responses vs. summaries).

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 Pipeworx data. It specifies inputs (slug, URL, question text) and outputs (evidence packet, comparison). It distinguishes itself from siblings by offering a combined research call for betting decisions.

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 gives explicit use cases: 'should I bet on X', 'what does the data say about Y', 'is there edge in Z'. It provides good guidance but does not explicitly mention when to use alternative tools among the large sibling set.

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 nature. The description adds significant behavioral context: data sources (SEC EDGAR/XBRL, FAERS), handling of off-calendar fiscal years, sorting by primary metric, and return of citation URIs. 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?

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 moderate complexity (2 params, no output schema), the description fully covers what data is returned, sorting, and citation format. It compensates for lack of output schema by explaining return structure clearly.

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 meaning beyond schema by explaining how values are interpreted (tickers/CIKs vs drug names), constraints (min/max items), and the data context (latest 10-K, FAERS counts).

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) with specific metrics for each type. It distinguishes from sibling tools by preferring over sequential single-pack lookups and quantifies efficiency (replaces 8–15 sequential lookups).

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 advises 'ALWAYS PREFER over sequential single-pack lookups when comparing entities' and provides trigger examples. It lacks explicit when-not-to-use scenarios but gives strong contextual 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 provides rich behavioral context beyond annotations: details on the research decomposition and parallel execution across 5,564 tools, the gap[] array behavior (never invented), the hop field and citation_uri stability, large-record semantic excerpting, approximate response times (15-90s), and depth-level specific behaviors (gap recovery, contradictions). The annotations are readOnlyHint=true, openWorldHint=true, idempotentHint=true, destructiveHint=false, and the description fully aligns and expands on these.

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 comprehensive but quite verbose at 24 sentences, covering many details including account requirements, technical architecture, output format, and edge cases. While most sentences earn their place, the density could overwhelm an agent, and key information (like breaking news limitations) could be more front-loaded. Some technical jargon like 'gap recovery' and 'hop' might be clarified earlier.

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 (2 parameters, no output schema, but complex behavior), the description does a thorough job covering prerequisites, input semantics, internal parallelism, output structure (findings packet with confidence, source, gaps[], contradictions[]), timing, and limitations. The only minor gap is the lack of explicit examples of the returned format, but the text is otherwise 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 description coverage is 100%, so the baseline is 3. The description adds useful context for the depth parameter by explaining the parallel facet counts and iterative behaviors (e.g., 'quick=3 (single hop)', 'thorough=6 (paid; adds a full iterative hop)') that go slightly beyond the schema enum descriptions. However, it doesn't add significant new constraints or format details for the question parameter beyond what the schema states ('natural language').

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 by immediately stating 'ACCOUNT REQUIRED' and then clearly describes a 'Grounded multi-source research across Pipeworx's 1462 STRUCTURED data sources' in one call. It uses specific verbs like 'decomposes', 'routes', and 'returns' to explain the tool's function. It also explicitly distinguishes itself from siblings like ask_pipeworx by noting this is not open-web search and is best for broad/multi-part structured queries.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit when-to-use and when-not-to-use guidance: 'Best for broad/multi-part questions over structured data' and explicitly tells the agent to use ask_pipeworx instead for single lookups, breaking news, or current-news topics. It also mentions the alternative ask_pipeworx for unauthenticated users and the need for a paid plan for thorough depth. This is exceptionally 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=true, idempotentHint=true, destructiveHint=false, so safety is clear. The description adds valuable context: returns 'top-N most relevant tools with names, descriptions, and full input schemas (with curated examples) — each result is ready to call directly, no second schema lookup needed', which describes behavior beyond the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

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 6 parameters (all aliases) and no output schema, the description adequately explains the return format (top-N with schemas and examples) and usage timing. It does not cover edge cases or failure modes, but for a tool discovery tool, this level of detail is 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% with each parameter described. The description adds value by clarifying that 'query' accepts aliases (task, q, description, search) and that it takes a natural language description, which is not perfectly captured in individual schema descriptions. However, the schema already handles basic semantics, so not a 5.

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 'Find tools by describing the data or task' and lists many specific domains (SEC filings, financials, etc.), clearly distinguishing 'discover_tools' from sibling tools like 'deep_research' or 'search_within' which are for different purposes.

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 readOnly, openWorld, idempotent, non-destructive. Description adds rich behavioral details: fans out across SEC EDGAR, XBRL, USPTO, news, GLEIF; returns specific data items; notes USPTO API sunset risk and fallback mechanisms. 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 a single dense paragraph that efficiently covers examples, purpose, usage, and return details. Every sentence adds value, but structure could be slightly improved (e.g., bullet points) for 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?

Despite no output schema, the description thoroughly lists all return fields (cik, company_name, recent_filings with URIs, fundamentals, patents, news, LEI) and sources. This is complete for a complex information 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%, so baseline is 3. Description adds value by explaining that value accepts ticker or zero-padded CIK, and type is currently limited to 'company'. This extra context justifies 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?

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 destructiveHint=true, so the destructive nature is known. Description adds 'clear sensitive data' context but does not disclose further behavioral traits (e.g., idempotency, read-only). 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?

Two sentences, no redundant words. First sentence states action, second provides usage guidance. Efficient and 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?

For a simple 1-parameter tool with annotations covering destructiveness, the description covers purpose, usage, and pairing with siblings. No missing context.

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% (description for 'key' matches schema). Description adds no additional meaning beyond the schema's 'Memory key to delete'.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives explicit when-to-use guidance: 'Use FIRST whenever you have a name but need an ID.' It also explains the tool replaces 2-3 manual lookups, reinforcing its role. While it doesn't explicitly list when not to use, the strong directive and context make the usage scenario 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?

No annotation contradiction; description adds behavioral details: probes each entity with ai_visibility_check, returns ranked list with score/confidence/signal density, beyond the annotations which already mark it as read-only and idempotent.

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 wasted words, front-loaded with purpose and output structure.

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 fully explains return format (ranked list with score, confidence, signal density per entity), sufficient for this aggregated probe 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%, but description adds value by clarifying that the first entity is treated as 'subject' and others as competitors, which is not in 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?

Description clearly states verb 'compare' and resource 'AI visibility across multiple entities', differentiating from sibling tools like ai_visibility_check (single probe) and compare_entities (generic).

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 explicit use case ('competitive AI-marketing audits') with example, but does not mention when not to use it or direct to alternatives for single entity probes.

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 valuable context about graceful degradation: 'Partial failures degrade gracefully — bundlephobia's first measurement on a new version can take 5-30s; sources_failed will list it if it times out, the rest still returns.' This goes 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 detailed and front-loaded with the core purpose. Each sentence adds value, covering purpose, usage, behavior, output structure, and edge cases. Slightly long but justified by thoroughness; 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?

Without an output schema, the description fully details the return structure: summary block fields, per-advisory detail, links, and alternative versions. It also addresses edge cases (timeout, partial failures). Complete for a 2-parameter 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 both parameters described. The description does not add extra semantic detail beyond what the schema provides, such as the default version behavior which is already in the schema. 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 clearly states it's a composite check for npm packages covering license, advisories, version history, and bundle size. It uses a specific verb 'scan' and resource 'dependency', and is distinct from sibling tools which focus on other domains (e.g., AI visibility, betting markets).

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 agent asks "is X safe / popular / small" or "what does adding lodash cost me"'. It also specifies ecosystem scope 'NPM ecosystem only in v1' and directs to deps.dev directly for other ecosystems. This provides clear when-to-use and 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?

Beyond annotations (readOnlyHint, etc.), description reveals technical details: BGE-base-en embeddings, cosine similarity, 500-char windows, 200K char cap with truncation and flagging, and that passages include offsets for verification.

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?

Concise, front-loaded with key action, uses bullet-point-like structure without symbols, every sentence adds necessary information without 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?

Covers purpose, usage, technical details, limitations, and return format (passages with offsets and scores). No output schema required given this clarity.

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 100%, but description adds value: provides example queries for the query parameter, clarifies the text size limit, and explains the purpose of the limit parameter.

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 'Semantic search INSIDE a fetched record' with specific verb and resource, and distinguishes by noting it pairs with ask_pipeworx_grounded, avoiding confusion with sibling 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 states when to use: 'when the record is too big to cram into the prompt' and how it saves context. Pairs with ask_pipeworx_grounded for grounding. Lacks explicit 'when not to use' but 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 goes beyond annotations by detailing subscription types with examples, delivery channel constraints (e.g., webhook auto-disabled after 10 failures, SMS daily cap), and that the feed is always on. 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 well-structured, starting with the main purpose, then requirements, supported types with examples, and delivery channels. Every sentence adds value, and it's concise 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 all subscription types, delivery channels, return value (subscription ID), and how to retrieve alerts. It also addresses prerequisites and constraints, making it complete for an agent to use the tool 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?

The input schema descriptions already cover parameter meanings with examples (100% coverage). The description adds extra behavioral context like the daily SMS cap and webhook signing details, but the schema already provides thorough documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

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

The description clearly states the tool creates a proactive monitoring subscription to a live-data event stream and returns the new subscription ID. It distinguishes from siblings like list_subscriptions and unsubscribe by focusing on creation.

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 context on when to use the tool (for persistent monitoring) and specifies prerequisites (requires Pipeworx OAuth account). It also details constraints for delivery channels (phone verification, 10 SMS cap). While it doesn't explicitly contrast with sibling tools, the usage 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 indicate readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds detailed behavioral context: it explains the return format (category-bucketed example questions with exact tool+argument shapes), that it draws from a live catalog, and how to optionally filter by 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 somewhat long (multiple sentences) but well-structured: it starts with common phrasings, then explains the output format, then usage and where to call it first. It is front-loaded with key information. Could be slightly trimmed, but overall efficient.

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 tool has zero required parameters and no output schema. The description fully explains what is returned (category-bucketed example questions with tool+argument shapes) and the source (live catalog). It also covers the optional topic parameter and gives usage context. Complete for the tool's simplicity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

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

Schema coverage is 100% with one parameter (topic) fully described. The description adds significant meaning: it explains that omitting topic returns a full spread, and passing a topic focuses the results, listing possible values like 'finance', 'pharma', etc. This goes beyond the schema's minimal 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's purpose: an onboarding entry point that returns category-bucketed example questions with tool+argument shapes. It uses specific verbs like 'suggest' and 'returns', and distinguishes from siblings like discover_tools and ask_pipeworx by focusing on onboarding and examples.

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 advises to use this tool first when the agent does not know what Pipeworx can do, and lists specific use cases like 'getting started' and 'what data do you have?'. It does not explicitly state when not to use it, 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?

Beyond annotations (idempotentHint=true, destructiveHint=false), the description explains the key behavioral detail: 'The row is deactivated (not deleted) so its historical events stay available via recent_alerts,' adding transparency 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?

The description consists of two concise sentences with no excessive wording. It front-loads the core action ('Cancel a subscription by id') and immediately follows with critical context, making it efficient 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?

For a simple single-parameter tool with no output schema and good annotations, the description is fully complete. It covers the action, constraint (ownership), and behavioral nuance (deactivation vs. deletion) without requiring additional information.

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 adequately described as 'Subscription id (uuid) returned by subscribe.' The description adds no additional semantic info beyond the schema, so a 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 clearly states 'Cancel a subscription by id' with a specific verb and resource, and distinguishes from sibling tools like 'subscribe' and 'list_subscriptions' by noting 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?

The description explicitly mentions 'Ownership is enforced — you can only cancel your own subscriptions,' providing important context for when to use. However, it does not explicitly state when not to use or name alternatives, which would elevate it to a 5.

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 substantial behavioral detail beyond the annotations: routing for company-financial vs other claims, the verdict set, the critical distinction between 'could_not_verify' and 'unsupported', and the error semantics with verification_error field. This is transparent and helps avoid misinterpretation.

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 dense and well-structured, with trigger phrases up front, clear sub-sections, and every sentence adding value. It is appropriately detailed for a tool with complex routing and error semantics, though it could be slightly tightened.

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 fully explains return values, verdict meanings, and error handling, making it self-contained for a caller. It covers the two claim categories, the fallback path, and the operational semantics of inconclusive results.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

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

Schema coverage is 100%, and the description adds meaningful nuance for tolerance_pct, explaining its override behavior, default cap of 5, and recommended settings for hallucination detection. The claim parameter is well illustrated in the schema, and the description reinforces its purpose.

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 function: natural-language claim verification against authoritative sources, with a specific verb and resource. It distinguishes itself from sibling tools by positioning itself as the fact-check/verify tool and 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?

Provides explicit usage guidance: 'Use whenever the agent needs to check whether something a user said is factually correct' with trigger phrase examples. It lacks explicit when-not-to-use instructions relative to sibling tools, but the consolidation note implies it is the primary verification entry point.

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