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 important behavioral context: default free model, optional Anthropic probing with BYO key (billing implications), and the return structure (per-model fields + combined view). No contradictions.

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

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

Four sentences with zero waste. The purpose is front-loaded, followed by key behavioral details and use cases. Every sentence adds essential 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?

Despite having 4 parameters and no output schema, the description covers purpose, parameters, return format (per-model fields + combined), and use cases. There are no gaps given the tool's simplicity.

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

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

Schema description coverage is 100%, but the description adds value beyond the schema: it explains the default for 'models', the condition for '_apiKey', and the disambiguation purpose of 'context'. This helps the agent understand parameter relationships.

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

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

The description uses specific verbs ('probe', 'score') and resources ('LLMs', 'visibility'), clearly distinguishing from sibling tools like 'ask_pipeworx' (which answers questions about a specific entity) or 'deep_research' (more extensive research). It specifies the output format and default model.

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 lists use cases: 'AI-marketing audits, pre-launch brand checks, competitive monitoring.' It does not explicitly state when not to use or compare to alternatives, but the context of sibling tools provides implicit guidance, and the description is clear enough for an agent to decide.

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 readOnly/openWorld/idempotent hints. The description adds valuable context about routing to 5,529 tools, filling arguments, and returning pipeworx:// citation URIs. It does not disclose potential failure modes or latency, but the annotation coverage plus added detail justifies a strong score.

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?

It provides sufficient context for an agent to select and invoke the tool correctly in virtually any factual query scenario.

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 aliases and examples already well-documented. The description adds no new parameter-specific meaning beyond restating that the user's natural-language question is the input. It meets the baseline for high coverage but does not elevate it.

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: it routes factual questions to a vast array of vetted sources and returns structured answers with citations. It distinguishes itself from siblings by explicitly naming ask_pipeworx_grounded and deep_research as alternatives for different use cases.

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 also explains when to step up to alternatives (ask_pipeworx_grounded for hallucination-resistant answers, deep_research for 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?

Annotations already establish read-only, idempotent, open-world, non-destructive behavior. The description adds valuable context beyond annotations: it discloses the experimental nature (candidate routing improvements enabled live), the current state (no active candidate as of 2026-07-26), and that it is a fully working router. This is essential behavioral information not conveyed by annotations.

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

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

The description is moderately sized with four sentences, but each sentence earns its place, covering purpose, current status, usage, and functionality. It is front-loaded with the core identity ('Beta version of ask_pipeworx'), though it could be slightly tighter without losing important context.

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 simple input (a question), the description sufficiently explains the tool's role, current state, and relationship to ask_pipeworx. It explicitly says 'same response shape' but doesn't detail the response format; however, since it references ask_pipeworx as a known sibling and there is no output schema, this is acceptable. The description is complete enough for an agent to select and 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%, with all parameters documented as aliases for 'question'. The tool description adds no additional parameter meaning, but not needed because the schema fully covers semantics. 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 what the tool is: a beta version of ask_pipeworx with identical functionality and candidate routing improvements. It explicitly distinguishes itself from the stable ask_pipeworx by noting its experimental nature, and the scope is well-defined as a universal router with the same 5,529 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?

It provides explicit when-to-use guidance: 'Use it exactly like ask_pipeworx when you want the newest routing.' It also clarifies that when no candidate is active, it matches ask_pipeworx exactly, and that it is a full working router, not a fallback or stub. This effectively tells the agent when to prefer it over the sibling ask_pipeworx.

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 (readOnly, openWorld, idempotent), the description discloses the refusal behavior with exact reason strings, the evidence field with verbatim quotes, and the rule to use ONLY tool result content.

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 are aliases for 'question,' with the main parameter clearly described. The tool description adds no parameter-specific meaning, but the schema already fully defines them. Baseline 3 is appropriate because the description does not hinder understanding and the schema carries the burden.

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 opens with a specific, clear purpose: 'Hallucination-resistant answer mode for high-stakes reads.'

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 (readOnlyHint, idempotentHint, destructiveHint) already convey safety. The description adds value by specifying return fields (calories, time, servings, ingredient lists) and example usage, which is helpful for an agent despite no output schema.

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 concise sentences plus an example. Front-loaded with action and resource. Every element serves a purpose; 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 6 parameters and no output schema, the description is fairly complete: it states the action, filters, and return values. It does not mention the optional _apiKey or default limit, but these are covered in the schema. Lacks pagination or rate limit warnings, but overall adequate.

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 clear descriptions for each parameter. The description mentions the optional filters (diet, health, cuisine) but does not add semantic detail beyond 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?

Description clearly states it searches Edamam's recipe database by keyword with optional filters, returning recipe details. While it doesn't explicitly differentiate from sibling 'search_food', the focus on recipes is specific enough to imply purpose.

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 an example and lists filters, implying use for recipe searches. However, it does not explicitly state when to use this tool over alternatives like 'search_food' or when not to use it.

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

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

Annotations already show safe read-only, idempotent behavior. Description adds algorithmic details (BGE-base-en embeddings, cosine, 500-char windows), truncation cap (200K chars with flag), and output structure (passages with offsets and scores), exceeding annotation coverage.

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?

Highly concise and front-loaded: first sentence captures the core purpose. Every sentence adds essential 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?

Despite no output schema, the description fully explains return values (passages with offsets and similarity scores), limits (200K chars, truncation), and pairs with a sibling tool. Complete for a semantic 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 covers all 3 parameters with descriptions. The description adds contextual meaning: 'text' is the fetched record, 'query' is natural-language with examples, 'limit' controls passage count. It also explains that passages carry offsets for verification, adding value 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 the tool performs semantic search inside a fetched record, with examples of use cases (SEC 10-K, articles) and distinguishes itself from siblings by noting it pairs with ask_pipeworx_grounded for grounding over passages.

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 provides an alternative (ask_pipeworx_grounded), giving clear usage 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 provide idempotentHint=true and destructiveHint=false, but the description adds valuable behavioral details: SMS cap (10/day), phone verification requirement, webhook auto-disable after 10 failures, and delivery channel options. However, there is a potential contradiction with idempotentHint since the description implies a new subscription ID is returned each time, which may conflict with idempotency.

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 the core purpose and uses structured bullet points for types and delivery channels. While slightly verbose, every sentence serves a purpose. A minor improvement would be to separate idempotency clarification.

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 value (subscription ID), all parameter types, delivery options, prerequisites (OAuth account, phone verification), and limitations (SMS cap, webhook auto-disable). It is sufficiently complete for an agent to correctly invoke the tool.

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

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

Schema coverage is 100%, and the description adds extensive meaning for each parameter, including type-specific examples (sec_8k, polymarket_edge, fred_series) and detailed delivery channel configurations (webhook signing, auto-disable). It fully compensates for the lack of schema-level descriptions.

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

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

The description clearly states the tool creates a proactive monitoring subscription to a live-data event stream, specifies types and delivery channels, and distinguishes it from siblings like list_subscriptions and unsubscribe.

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

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

It explains when to use (create subscription), mentions requirements (Pipeworx OAuth account, cannot use anonymous/BYO), and implies alternatives (list_subscriptions to view existing, unsubscribe to remove). Explicit contraindications or when-not-to-use are not stated, but the context is clear enough.

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 valuable behavioral context: it returns 'category-bucketed example questions (company financials, drugs & clinical trials, ...) each with the exact tool + argument shape' and is drawn from a live catalog. 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 synonyms and then the core purpose. It is slightly long but each sentence adds value. It is front-loaded with the main use case. Could be marginally trimmed but remains highly informative.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (one optional parameter, no output schema), the description is complete. It covers purpose, when to use, what it returns (category-bucketed examples), and how to call it. No gaps.

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 'topic'. The description adds meaning: it explains the possible values ('finance, pharma, economics, etc.') and that omitting gives a cross-category spread. This goes beyond the schema's description.

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

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

The description clearly states the tool's purpose: it returns category-bucketed example questions with exact tool and argument shapes. It uses specific verbs ('returns', 'draws from') and resources ('category-bucketed example questions', 'live catalog'). It distinguishes itself from siblings by positioning as the onboarding entry point for an agent that just connected.

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 when to use it: 'Use this FIRST when you do not yet know what Pipeworx can do for you' and 'Call with no arguments for the full spread, or pass topic to focus'. It also mentions alternative meta-tools but does not explicitly state when not to use it. However, the guidance is clear and direct.

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 value beyond annotations by specifying ownership enforcement, deactivation (not deletion), and the relationship with recent_alerts. This complements the annotations (readOnlyHint=false, destructiveHint=false, idempotentHint=true) without contradiction.

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

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

Three sentences, each serving a distinct purpose: action, ownership, and behavioral effect. No fluff, front-loaded with the primary action.

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 the main behavioral aspects but lacks return value information. Since there is no output schema, a brief note on what is returned would improve 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% and the schema already describes the id parameter. The description only mentions 'by id' without adding new meaning, so it does not significantly enhance parameter 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?

The description clearly states 'Cancel a subscription by id,' which is a specific verb-resource combination. It distinguishes from siblings like subscribe and list_subscriptions by focusing on cancellation and ownership.

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 implicitly tells when to use (to cancel a subscription) but does not explicitly contrast with alternatives. It does mention ownership enforcement and that historical events are preserved via recent_alerts, providing context for 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?

Annotations already declare read-only, open-world, and idempotent hints, but the description adds crucial behavioral context: the distinction between could_not_verify (check did not happen) and unsupported (no source exists), and the warning that could_not_verify is not evidence. It also discloses the internal routing logic (SEC EDGAR vs grounded pipeline) and return structure.

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 well-structured, starting with example phrasings, then purpose, routing, return value, and important warnings. Every sentence adds value, though the 'Replaces 4–6 sequential calls' is a nice-to-have and the text is fairly long, keeping it from a perfect 5.

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 and absence of an output schema, the description thoroughly covers use cases, internal routing, verdict types, citation format, reasoning, and edge-case semantics. It also warns about the could_not_verify vs unsupported distinction, which is essential for correct handling.

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 already contains detailed descriptions for both parameters (100% coverage), so the baseline is 3. The description adds marginal value by noting 'exact percent-delta math' and the tolerance override for hallucination detection, but does not deeply elaborate on parameter formatting or constraints 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 natural-language claim verification against authoritative sources, with a specific verb (verify) and resource (claims). It distinguishes itself from sibling tools by focusing on factual correctness judgments with a verdict output and explicitly mentions replacing multi-step pipelines.

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 provides explicit guidance on when to use ('Use whenever the agent needs to check whether something a user said is factually correct') and explains the two routing paths for financial vs other claims. However, it does not explicitly name alternative tools or state exclusions, though it implies a consolidated workflow.

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