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

Annotations declare readOnly, openWorld, idempotent, non-destructive. Description adds: probes LLMs, scores 0-100, returns per-model details, and explains _apiKey usage with direct billing by Anthropic. No contradictions; description enriches annotation context.

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

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

Single paragraph, no wasted words. Front-loads main function, then provides essential details on models, API key, and return structure. 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 4 parameters, no output schema, but robust annotations, the description covers return format (per-model score/confidence/signals/raw_response + combined view), use cases, and cost implications. Minor improvement could be to mention rate limits or pagination, but overall 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%, so each parameter has a description. Description adds meaning: explains _apiKey is passed straight through to Anthropic and required only if 'anthropic' in models; notes default model is 'workers-ai' and free. Goes beyond schema with practical context.

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 visibility scoring, with a specific verb 'probe' and resource 'LLMs for what they know about a business/brand/product/topic'. It distinguishes itself from sibling tools like 'ask_pipeworx' or 'bet_research' by focusing on AI visibility measurement.

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 lists use cases: AI-marketing audits, pre-launch brand checks, competitive monitoring. Explains default model and optional Anthropic probe with BYO key. Does not explicitly state when not to use, but context signals and sibling diversity make alternatives 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 safe read (readOnlyHint, destructiveHint false) and open world. Description adds context about returning structured answers with citation URIs and routing to internal tools. No contradiction; description enriches but doesn't cover all edge cases (e.g., rate limits).

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

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

Schema description coverage is 100% with each parameter documented as an alias for 'question'. The description adds limited value beyond the schema, only stating that the question is in natural language and used for routing. Baseline 3 is appropriate.

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

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

The description clearly states it is a hallucination-resistant answer mode for high-stakes reads, explicitly distinguishing it from the sibling tool ask_pipeworx by explaining the extra extraction step and cost. The verb 'extracts' and resource 'tool result' are specific.

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 (high-stakes, when answer will be quoted/cited/acted on, must not invent facts) and when not to (prefer ask_pipeworx for casual lookups), listing specific domains like financial, legal, medical claims.

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=true, idempotentHint=true, destructiveHint=false). It discloses numerous behaviors: market resolution, classification, fan-out, response shapes, resolver contract with match confidence, parent event extraction, news fallback handling, safety short-circuits, closed/dead market handling, wide spread warnings, and cancellation rule parsing. This provides agents with deep insight into tool behavior.

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

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

While verbose, the structure helps agents parse critical points. Minor improvement could be trimming redundant examples while retaining essential guidance.

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, rich behavior, no output schema), the description covers virtually every aspect: what it does, when to use, how it works, what to expect in the response, edge cases, safety mechanisms, and resolution rules. It is comprehensive and leaves little ambiguity for an AI agent.

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

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

Schema coverage is 100% (all parameters described). The description adds meaning beyond the schema by explaining how 'depth' affects evidence sources (quick vs thorough), how 'include_raw' controls response size, and how the 'market' parameter accepts slugs, URLs, or question text. These details help agents choose correct parameter values.

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

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

The description explicitly states the tool'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 via Pipeworx), and provides numerous usage examples, clearly distinguishing it from sibling tools by being a one-call research 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?

The description provides explicit use cases: 'Use for "should I bet on X", "what does the data say about Y", or "is there edge in Z".' It also details blocking conditions (low-confidence matches, closed markets, wide spreads) and offers examples. While it doesn't directly contrast with sibling tools like polymarket_edges, the context is rich enough to guide appropriate use.

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, destructiveHint=false. Description adds no behavioral details beyond stating it returns stages; does not disclose ordering, pagination, or data completeness.

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

Explicitly says when to use: 'is X safe / popular / small' or 'what does adding lodash cost me'. Also provides exclusion: 'NPM ecosystem only in v1; PyPI / Maven / Cargo / Go fall under deps.dev:version directly.'

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 provide readOnlyHint, idempotentHint, and destructiveHint. The description adds the specific searchable fields (title, session, stage, member), which supplements the annotations without contradicting them. No behavioral traits beyond annotations are disclosed, but the description is consistent.

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?

A single, well-structured sentence that conveys the core purpose without extraneous words. Every part adds value, making it efficient for an AI agent to parse quickly.

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 presence of an output schema and full parameter coverage, the description provides sufficient context for a search tool. It could mention pagination (skip/take) briefly, but those are documented in the input schema. Overall, 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 description coverage is 100%, so the schemas already define each parameter. The description merely lists some parameters but adds no deeper semantic meaning beyond what the schema provides. The examples in the schema compensate partially.

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

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

The description states 'Search bills by title / session / stage / sponsoring member,' which clearly specifies the verb (search), resource (bills), and filtering parameters. It distinguishes from sibling tools like 'get_bill' (single bill retrieval) and 'search_members' (search by member).

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?

While the description implies use for searching bills, it lacks explicit guidance on when to use this tool versus alternatives such as 'search_hansard' or 'search_members'. However, the context of 'bills' and distinct sibling names makes context clear enough for an agent.

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 lack of destructiveness. The description adds no behavioral context beyond stating the resource: 'debate contributions'. It does not discuss return format, pagination, or other behaviors, which are partially covered by 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?

The description is a single short sentence, which is concise but too minimal. It repeats the title and could be more informative without adding verbosity.

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 the presence of an output schema and detailed parameter descriptions, the tool description lacks context such as what the search returns, time range, or typical usage patterns. For a search tool with 7 parameters, this is insufficient.

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%; every parameter has a clear description. The tool description does not add any additional meaning beyond the schema, so baseline 3 is appropriate.

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

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

The description clearly states the verb 'Search' and the resource 'debate contributions in Hansard', which is distinct from sibling tools like search_bills or search_members. It accurately reflects the tool's 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 no guidance on when to use this tool versus alternatives. It does not mention scope, prerequisites, or typical use cases, leaving the agent to infer from the name alone.

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

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, so the description does not need to reiterate safety. The description adds no further behavioral context (e.g., rate limits, pagination behavior, or what happens with zero results). It is adequate but minimal.

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, front-loaded sentence that wastes no words. It conveys the core purpose immediately and is highly 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?

Given the tool has 7 optional parameters and an output schema, the description is minimal. It does not explain how to combine filters or what the response looks like (though output schema covers return values). The examples in the schema help, but the description could be more helpful for a search tool with many optional fields.

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 covers 100% of parameters with descriptions. The description provides a high-level summary of search dimensions but does not add meaning beyond what the schema already offers. Baseline 3 is appropriate for full schema 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?

The description clearly states the verb (Search) and resource (MPs and Lords), and specifies the filter dimensions (name, party, location, house). It effectively distinguishes this tool from siblings like get_member (which retrieves a specific member) and search_bills (which searches bills).

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

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

The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, limitations, or when not to use (e.g., when you need a specific member instead). The agent must infer usage from the tool name and parameters alone.

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, idempotentHint, etc.), the description adds significant behavioral details: uses BGE-base-en embeddings + cosine similarity over 500-char overlapping windows, cap of 200K chars with truncation and flagging, and returns passages with character offsets and similarity scores. 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 paragraph but well-structured: core purpose in the first sentence, then usage guidance, benefits, pairing hint, and technical details. Every sentence provides unique information without redundancy, making it efficient for an agent to parse.

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 moderate complexity (3 parameters, no output schema), the description covers all essential aspects: what it does, when to use it, technical implementation (embeddings, window size, similarity metric), limitations (character cap), and return format (passages with offsets and scores). This completeness enables an agent to invoke it correctly without ambiguity.

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

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

Schema coverage is 100%, so the baseline is 3. The description adds value by specifying the character limit for 'text' (max ~200K chars), providing a natural-language query example for 'query', and clarifying that 'limit' has a default of 5 and range 1-20. This extra context justifies a score above baseline.

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

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

The description clearly states the tool performs semantic search inside a fetched record, using a natural-language query to return top-N passages with offsets and similarity scores. It distinguishes from siblings by explicitly pairing with ask_pipeworx_grounded and clarifying that it saves context by returning only relevant passages instead of the whole document.

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 when to use the tool: 'Use when the record is too big to cram into the prompt.' It also mentions pairing with ask_pipeworx_grounded for a grounded workflow. However, it does not explicitly state when not to use it or list alternatives beyond that sibling, though the intent 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 indicate idempotentHint=true and destructiveHint=false, which align with the description's mention of returning a subscription ID and persisting the subscription. The description adds critical details beyond annotations (OAuth requirement, delivery channel constraints, event types). 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 moderately long but well-structured front-loading the action and requirements. Every sentence adds value, though slightly verbose for a tool with many options.

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 complex tool with 3 parameters (including nested objects) and no output schema, the description covers requirements, type-specific details, delivery channel limitations, and return value ('subscription id'). No significant 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%, and the description enriches each parameter with examples and functional details (e.g., type values with item codes, params structures, delivery channels with verification and rate limits).

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

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

The description clearly states 'Create a proactive monitoring subscription to a live-data event stream', which is specific and differentiates from sibling tools like 'unsubscribe' and 'list_subscriptions'.

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

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

The description provides explicit context: requires Pipeworx OAuth account, lists supported types and delivery channels, and implies usage for persistent monitoring. However, it does not explicitly contrast with alternatives like 'list_subscriptions'.

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, and destructiveHint=false. The description adds value by explaining it returns 'category-bucketed example questions... drawn from the live catalog' and the exact tool+argument shape, which is beyond what annotations provide. 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 front-loaded with common query phrases and efficiently packs significant detail (purpose, usage, outcome) in a few sentences. Slightly long but justified by the amount of useful 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 absence of an output schema, the description adequately describes the return type (category-bucketed example questions with tool+argument shapes). It also covers the optional topic parameter and use cases, making it sufficiently complete for this onboarding 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 one parameter. The description adds context by listing example topics ('finance', 'pharma', etc.) and explaining the effect of omitting the parameter, which goes beyond the schema's basic 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 uses specific verbs like 'returns category-bucketed example questions' and clearly identifies the tool as the onboarding entry point, distinguishing it from siblings like 'discover_tools' or 'ask_pipeworx'.

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

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

Explicitly states 'Use this FIRST when you do not yet know what Pipeworx can do for you' and gives context for when to call with or without the topic argument. No explicit when-not-to-use, but the guidance 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?

Discloses key behaviors: ownership enforcement, deactivation vs deletion, and link to recent_alerts. Annotations (destructiveHint false, readOnlyHint false) align with description. OpenWorldHint true suggests possible undocumented side effects, but description covers main behavior.

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

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

Two efficient sentences that front-load the action and include all key information without waste.

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 one parameter, no output schema, and annotations, the description fully covers what the agent needs to know: purpose, constraints, and outcome (deactivation, not deletion). 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?

Single parameter 'id' with schema description 'Subscription id (uuid) returned by subscribe.' This adds context beyond the schema (origin of the id). Schema coverage is 100%, so baseline is 3; description adds 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?

Explicitly states 'Cancel a subscription by id' and distinguishes from sibling tools like subscribe. Mentions ownership enforcement and that the row is deactivated, not deleted, providing clarity on the exact operation.

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 when-to-use guidelines: ownership is enforced (only cancel own subscriptions) and the row is deactivated (not deleted) so historical events remain available via recent_alerts. This helps the agent decide when to use this tool vs 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 provide readOnlyHint, openWorldHint, idempotentHint, and destructiveHint false. The description adds value by explaining the tool replaces multiple sequential calls and returns a verdict with structured data, enhancing transparency 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 somewhat long but front-loaded with query examples and usage context. Every sentence serves a purpose, though it could be slightly more concise without losing value.

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

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

Given the single parameter, no output schema, but comprehensive annotations, the description is complete. It explains the tool's scope, consolidated nature, and return structure, requiring no additional 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% with a well-described 'claim' parameter including examples. The description does not add additional parameter semantics beyond what the schema provides, 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 the tool verifies natural-language claims against authoritative sources, specifically company-financial claims. It provides example queries and explicitly distinguishes from other tools by focusing on fact-checking versus other functions.

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 says 'Use whenever the agent needs to check whether something a user said is factually correct' and gives concrete examples. While it does not explicitly list when not to use, it implicitly limits the scope to company-financial claims, providing adequate guidance.

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