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

Annotations already mark the tool as readOnly, openWorld, idempotent, and non-destructive. The description adds critical behavioral details beyond annotations: it returns per-model {score, confidence, signals, raw_response} plus a combined view, and explicitly states that probing Anthropic requires a BYO key and that the user pays Anthropic directly. This cost and key-handling information is valuable for the agent.

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, well-structured paragraph with two sentences. The first sentence front-loads the core action and output. Every sentence adds value: purpose, default behavior, optional key handling, return format, and use cases. 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?

Given the tool has 4 parameters (1 required), no output schema, and annotations covering safety, the description is complete. It explains the return format, default model, optional Anthropic integration with cost implications, and multiple use cases. The agent can understand the tool's full capability and constraints 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 description coverage is 100%, so the baseline is 3. The description adds concrete examples for each parameter (e.g., 'Pipeworx' for entity, 'workers-ai' for models, 'sk-ant-...' for _apiKey, 'Boston restaurant' for context), which helps the agent form correct invocations. This extra detail raises the score to 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 probes LLMs for knowledge about an entity and returns a visibility score per model. It specifies the verb 'probe', the resource 'one or more LLMs', and the output format. The description also distinguishes from sibling tools by mentioning specific use cases like 'AI-marketing audits, pre-launch brand checks, competitive monitoring', which are not covered by siblings such as 'scan_competitor_ai_presence'.

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 contexts for use: AI-marketing audits, pre-launch brand checks, competitive monitoring. It also explains optional probing with Anthropic via BYO key. However, it does not explicitly state when not to use the tool or suggest alternatives among siblings, missing an opportunity for full 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?

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is well covered. The description adds substantial behavioral context: routing behavior, source count, output format (citation URIs), tier availability, and performance characteristics ('one fast call'). It does not mention potential limitations like rate limits or query complexity ceilings, but the added context is meaningful.

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 front-loaded with the core directive ('PREFER OVER WEB SEARCH') and well-organized with bold text and examples. Every section contributes: purpose, usage triggers, alternatives, examples, and operational notes. A few phrases are somewhat redundant (e.g., 'START HERE' and 'default entry point'), but overall it is dense with actionable information.

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

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

For a complex routing tool, this description is remarkably complete: it covers purpose, usage, alternatives, query domains, output format (structured answer with citation URIs), performance, tier compatibility, and even mentions news routing. Since there is no output schema, the inclusion of 'returns the structured answer with stable pipeworx:// citation URIs' adequately explains return values. Sibling differentiation and exclusion criteria are also well documented.

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 six params are documented as aliases for question). The description goes beyond the schema by providing natural-language query patterns ('what is', 'look up', 'current') and concrete examples that clarify the expected input format. This adds semantic value beyond the field name and alias list.

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

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

The description clearly identifies the tool as a question-routing gateway that aggregates data from thousands of sources, with a specific verb ('routes'), resource ('5,529 tools across 1455 verified sources'), and output ('structured answer with citation URIs'). It explicitly distinguishes itself from siblings like ask_pipeworx_grounded and deep_research, 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 usage directives: 'PREFER OVER WEB SEARCH', 'START HERE for most questions', and gives concrete examples of when to use alternatives ('for a hallucination-resistant single answer use ask_pipeworx_grounded; for a broad/multi-part question use deep_research'). This is among the strongest usage guidance possible.

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, idempotent, and non-destructive hints. The description adds critical behavioral context: beta status, live candidate testing, current exact match to stable, and comparison against stable for merges. This goes well beyond annotations and informs the agent of the experimental edge behavior.

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

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

The description is concise and front-loaded, immediately stating 'Beta version of ask_pipeworx'. Each sentence adds value: identical router specs, current state, usage directive, and reassurance of full functionality. No redundancy or fluff.

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

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

For a complex router with a simple input schema and no output schema, the description is complete. It explains the purpose, current status, usage context, and response shape (via 'same response shape' reference), enabling an agent to select and invoke the tool appropriately without missing key details.

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 all params (q, text, input, query, prompt, question) described as aliases. The description merely says 'same arguments' without adding extra meaning or semantics beyond the schema. Baseline 3 applies as the schema does the heavy lifting.

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 this is a beta version of ask_pipeworx, an identical universal router with the same tools, arguments, and response shape. It distinguishes itself from the stable ask_pipeworx by noting experimental routing improvements, making the purpose specific and differentiating it from siblings.

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 instructs to 'Use it exactly like ask_pipeworx when you want the newest routing' and contrasts with the stable router, giving clear when-to-use guidance. It also clarifies that it is a full working router, preventing confusion about fallbacks.

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 readOnly/openWorld/idempotent annotations, the description discloses the exact return shape, explicit refusal reasons, and the extra LLM call cost. It explains that answers are extracted only from tool results, providing rich behavioral context without contradicting 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 informative but somewhat lengthy. However, every sentence earns its place—covering mechanism, return format, usage, and cost tradeoff. Front-loaded with purpose, making it easy to skim.

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 specifies the return structure including success and refusal cases, and provides enough context about routing and data sources. The sibling differentiation and clear usage rules make this complete for the tool's complexity.

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

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

The schema fully covers all parameters (100% coverage) with clear descriptions of aliases for the question field. The description adds no additional parameter-specific meaning, but the baseline of 3 is appropriate since the schema does the heavy lifting.

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

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

The description clearly identifies the tool as a hallucination-resistant answer mode, differentiating it from ask_pipeworx by emphasizing grounded extraction solely from tool results. The specific use case (quoted/cited/acted-on answers) and the contrast with the sibling tool establish a clear 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?

Explicit guidance is provided: use when answers will be quoted, cited, or acted on, and prefer ask_pipeworx for casual lookups due to the extra LLM call cost. This clearly states 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?

The description discloses many behavioral traits: low-confidence short-circuits, closed market handling, wide-spread warnings, resolution-rule risk, fallback mechanisms for news, and more. Annotations indicate read-only, idempotent, non-destructive, which match the description. 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 long but well-structured: starts with a one-sentence summary, then details classifiers, fan-out examples, response shapes, resolver contract, etc. Every section adds necessary detail for correct usage. Slightly verbose but justified by 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?

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 that the tool researches Polymarket bets by pulling Pipeworx data. It specifies the input (slug, URL, or question text) and output (evidence packet + market-vs-model comparison). It distinguishes itself from siblings like polymarket_edges by focusing on a single bet with deep evidence.

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?

Explicit use cases are given: 'should I bet on X', 'what does the data say about Y', 'is there edge in Z'. It also advises to inspect market_match fields before trusting analysis. However, it does not explicitly mention when not to use it or alternatives for multi-bet comparisons.

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?

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

Annotations already declare readOnlyHint and idempotentHint, but the description dramatically expands behavioral disclosure: 'returns a findings packet: verbatim evidence + confidence + source + fetched_at + a stable pipeworx:// citation per finding, with explicit gaps[]', 'contradictions[] flagging findings that disagree', 'semantically excerpted to the passages relevant to each facet (not head-truncated)', latency expectations, and account/pricing requirements. This is far beyond what annotations alone convey.

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 every sentence earns its place—it covers account requirements, core mechanism, alternatives, depth semantics, output format, and latency. It is front-loaded with the critical account gate first. However, it reads as a dense wall of text; breaking it into short paragraphs or bullets would improve scannability, so it falls just short of a 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 high complexity, the description covers all essential contexts: return payload structure, gaps[], contradictions[], citation deduplication ('always fetchable'), excerpting behavior, latency, and fallback guidance. There is no output schema, so the description appropriately explains the return value composition in detail. This is a complete, self-sufficient description.

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 detailed descriptions for both parameters, so the baseline is 3. The description adds extra meaning by tying the 'depth' parameter to account tiers ('depth:"thorough" needs a paid plan'), noting the default is 'standard', and explaining the behavioral consequences of each depth level (gap-recovery hop, follow-up leads, contradictions scan). This nuance goes slightly beyond the schema's already thorough enum descriptions.

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

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

The description clearly identifies a specific verb+resource+scope: 'Grounded multi-source research across Pipeworx's 1455 STRUCTURED data sources... in ONE call.' It also distinguishes itself from siblings by explicitly stating 'this is NOT open-web search' and contrasting with ask_pipeworx for single lookups, leaving no ambiguity about what this tool uniquely does.

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 when-to-use guidance: 'Best for broad/multi-part questions over structured data,' and when-not-to-use: 'For a single lookup use ask_pipeworx,' 'For BREAKING or colloquial CURRENT-NEWS... prefer ask_pipeworx.' It also names the alternative tool and states an account-tier caveat ('If you are not signed in, use ask_pipeworx instead'). This is exemplary usage-orientation.

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, destructiveHint. Description adds return format: 'top-N most relevant tools with names, descriptions, and full input schemas (with curated examples) — each result is ready to call directly.' 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.

Description clearly states it retrieves a full team profile by numeric team_id and lists specific return fields. Distinguishes from sibling tools like search_teams (which searches by name) and league_teams (gets teams in a league).

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?

Description implies usage when you have a numeric team_id. While it does not explicitly state when not to use or name alternatives, the context of sibling tools provides clarity. A brief note about alternatives would improve 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 declare readOnlyHint, openWorldHint, idempotentHint true, and destructiveHint false, so the safe, nondestructive behavior is clear. The description adds minimal context ('standings table') but does not disclose pagination, ordering, or handling of missing data. With strong annotations, the additional value is limited but acceptable.

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, front-loaded sentence that directly states what the tool does. No unnecessary words or redundancy.

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

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

Given the simple purpose, an output schema (not shown) likely describes the return structure, so the description does not need to cover that. However, it misses default behavior (current season) and edge cases. It is adequate but not thorough.

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 50% (only 'season' has a description). The tool description does not elaborate on either parameter. It does not explain what 'league_id' expects or how 'season' should be formatted beyond the example. This fails to compensate for the missing schema descriptions.

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

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

The description 'Standings table for a league/season' clearly states the tool returns a standings table for a given league and season. The verb is implicit but understandable. It distinguishes from sibling tools like 'league_teams' or 'get_team' by specifying 'standings' vs. team-level data.

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

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

No guidance is provided on when to use this tool versus alternatives. For example, it does not mention when to prefer this over 'league_teams' or 'search_teams'. The agent is left to infer the context.

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, covering safety and mutation. The description adds no behavioral details beyond what's in the schema (e.g., return fields). With rich annotations, the description adds minimal value.

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, concise sentence that immediately states the core functionality and output. No extraneous words or repetition.

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 list tool with one parameter, rich annotations, and an output schema, the description covers the essential purpose and output fields. It does not mention pagination or limits, but the open world hint and tool nature imply all teams are returned.

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 0%, and the description does not explain the 'league_id' parameter's meaning, format, or source. The schema only shows a type and example. The description fails to add semantic context for the single 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 the verb 'list', the resource 'teams', the scope 'by league_id', and the return fields (id, name, badge, country). It distinguishes the tool from siblings like 'get_team' (single team) and 'search_teams' (search).

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?

Usage is implied for listing teams by league, but no explicit when-to-use, when-not-to-use, or alternatives are given. While straightforward, it lacks guidance on edge cases or when to prefer this over 'search_teams' or team-specific 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 readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is known. The description adds context about the data source, return fields, and that the ID is used by other tools, which goes beyond what the 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?

Two sentences, front-loaded with the action and parameters, then return values and downstream use. No redundant information; every sentence earns its place.

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

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

Given the tool's simplicity, the description covers purpose, filtering, output, and usage context. The output schema exists, so return structure is handled elsewhere, and the description is complete 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?

The input schema already has descriptions for sport and country, with 100% coverage. The description reinforces that both are optional and provides example sport values, clarifying the narrowing behavior and adding value 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 uses a specific verb ('List') with a clear resource ('sports leagues catalogued by TheSportsDB') and explains filtering options. It also distinguishes itself by noting the league id feeds league_teams and league_table, setting it apart from sibling tools like list_sports.

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 tool has 0 parameters and schema description coverage is 100%, so the description does not need to explain parameters. Per guidelines, 0 parameters yields a baseline of 4. The description adds value by describing the output, but that is not parameter semantics.

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 'Return' and the resource 'all sports tracked by TheSportsDB', with examples (Soccer, Ice Hockey, Basketball) and specifies output fields (id, name, forum). This distinguishes it from siblings like list_leagues, which also lists entities but of a different type.

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

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

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

Beyond the annotations, the description discloses the two-phase claim_token flow, rate-limiting ('5 per identifier per day'), quota impact ('doesn't count against your tool-call quota'), and human review cadence ('digests daily'). These are non-obvious behaviors that significantly aid an agent in predicting outcomes.

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

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

The description is longer than average but every sentence serves a purpose: it defines the tool's scope, gives examples, warns about exclusions, explains the claim_token flow, and states limits. The structure progresses from 'what' to 'when' to 'how', and it is fully front-loaded with the core purpose.

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

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

For a tool with a nested context object, no output schema, and a multi-step claim_token workflow, the description is exceptionally complete. It covers all major aspects: intended use, what not to use it for, the return token, rate limits, and roadmap impact. The agent is well-equipped to decide when and how to invoke this 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?

Although schema coverage is 100% and each parameter already has a description, the tool description adds valuable semantics: it explains how claim_token is used to retrieve resolution status ('pass it back later... to read whether it was fixed'), and instructs users to describe issues in terms of Pipeworx tools/packs rather than pasting prompts. This goes beyond what the schema provides.

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

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

The description opens with a specific verb and resource: 'Tell the Pipeworx team something is broken, missing, or needs to exist.' It clearly differentiates itself from sibling tools like ask_pipeworx or discover_tools by framing itself as the channel for reporting issues, gaps, or praise about Pipeworx 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?

The description provides explicit when-to-use scenarios: bug, feature/data_gap, praise. It also gives an exclusion rule: only for tools served by this Pipeworx connection, and directs users to file issues with other MCP servers. The line 'Not sure? Pipeworx tool names are the ones this connection lists' offers a practical disambiguation.

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 destructiveHint=false. The description adds valuable detail about multi-source fan-out, fallback logic (GDELT→GNews), and soft-failure for USPTO, which 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 comprehensive but slightly verbose with multiple example queries. It is well-structured and front-loaded with purpose, but could be trimmed 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?

The tool is complex with multiple sources and fallback logic. The description fully explains behavior, parameters, and return structure (grouped changes, total count, citation URIs). No output schema, but description provides sufficient info.

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 parameters with descriptions. The description adds meaning by explaining 'since' accepts ISO or relative formats and suggests '30d'/'1m', and that 'value' can be ticker or CIK. This enhances 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 provides a 'change feed for a company in the last N days/weeks/months'. It gives numerous example queries and explicitly distinguishes itself from the sibling tool entity_profile.

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 includes explicit usage context ('What's new with X', 'latest on Y') and an alternative ('Use entity_profile instead when you want the static profile'). It also advises on typical 'since' values.

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=false, idempotentHint=true, destructiveHint=false. The description adds valuable behavioral context: data is scoped by identifier, persistent for authenticated users, and 24-hour retention for anonymous sessions. 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?

Three sentences, front-loaded with the primary purpose. No fluff; every sentence adds critical information. 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 no output schema, the description could mention the return value (e.g., success indication). However, it adequately covers persistence, scope, and pairing with other tools. It might also clarify behavior on overwrite, but idempotentHint suggests idempotent.

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

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

Schema coverage is 100% with descriptions for both key and value. The description adds semantic value by providing example key patterns (e.g., 'subject_property', 'target_ticker') and value types (findings, addresses, preferences, notes), enhancing 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 uses clear verbs ('Save data the agent will need to reuse later') and specifies the resource (key-value pair). It distinguishes from sibling tools recall and forget by mentioning them, making the tool's purpose distinct.

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

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

The description explicitly states when to use the tool: 'Use when you discover something worth carrying forward' and provides concrete examples (resolved ticker, target address, etc.). It also mentions pairing with recall and forget, guiding the agent on 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 cover readOnly, openWorld, idempotent, and non-destructive. The description adds valuable behavioral context: identifiers are labelled with their source, unresolved identifiers are explicitly stated, and LEI/FIGI enrichment degrades gracefully if external sources fail. It also discloses the cascading internal lookup behavior. 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 dense paragraph, but each sentence carries specific information: examples, directive, type details, return semantics, degradation behavior. Though not broken into sections, it is not needlessly long and avoids fluff. The front-loaded examples and 'Use FIRST' directive make it easy to grasp 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?

There is no output schema, so the description must explain return values. It does so for both types, including the 'unresolved' field and graceful degradation. It covers the tool's complexity (cascading lookups, multiple identifier sources) sufficiently. Slight gap: no mention of error handling for invalid input types, but the enum schema mitigates that. Overall, it is complete for its intended use.

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

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

The input schema already documents both parameters with 100% coverage. The description adds meaning by explaining the return payload for each type (e.g., company resolves a 'cross-source identity spine' with CIK, ticker, LEI, FIGI; drug returns RxCUI + ingredient + brand). It also clarifies acceptable values (ticker, CIK, name for company; brand/generic for drug) and the 'unresolved' behavior, which goes beyond the schema's basic 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 opens with concrete user queries and then states the core purpose: resolve a user-spoken NAME to canonical/official identifiers. It goes beyond a simple verb+resource by specifying the input types (company, drug) and the output identifiers (CIK, LEI, FIGI, RxCUI, etc.). It also distinguishes itself from siblings with the directive 'Use FIRST whenever you have a name but need an ID.'

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 when-to-use guidance ('Use FIRST whenever you have a name but need an ID') and notes that it replaces 2-3 manual lookups. It does not explicitly state when NOT to use or name specific alternatives, but the directive is strong and the context is clear. A 4 reflects the clear guidance without full exclusions.

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 behavior. The description adds context that the tool internally calls ai_visibility_check for each entity, returns scores, confidence, and signal density, and requires an Anthropic API key if probing with that model. No contradictions with annotations, and the additional behavioral detail is valuable beyond structured hints.

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

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

The description is two sentences totaling ~50 words, with no filler. It front-loads the primary action, then details the process and output. Every sentence adds value: purpose, mechanism, use case, and return format.

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 4 parameters and no output schema; the description explains the output format (ranked list with score, confidence, signal density). It does not mention the 2-8 entity constraint (already in schema) or error handling. However, given the annotations and schema richness, the description is sufficiently complete for an AI agent to understand how to invoke the tool.

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

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

Schema coverage is 100% with descriptions for all 4 parameters. The description adds extra meaning beyond the schema: it explains that the first entry in 'entities' is treated as the 'subject' for narrative purposes, and clarifies that 'models' can be omitted for just workers-ai. This enhances understanding without repeating schema content.

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

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

The description clearly states the tool compares AI visibility across multiple entities side-by-side, probes each with ai_visibility_check, ranks by score, and surfaces most/least recognized. It provides a concrete use case example ('does Claude know about us as well as our competitors?') and distinguishes itself from sibling tools like ai_visibility_check (single entity) and compare_entities (generic comparison).

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

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

The description explicitly says the tool is useful for competitive AI-marketing audits and gives a sample question. It implies when to use (comparing multiple entities) but does not explicitly state when not to use it or list alternative tools for single-entity checks. The context is clear but lacks explicit exclusions.

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), the description adds behavioral details: fans out to two services, returns summary and per-advisory detail, and notes potential 5-30s delay on bundlephobia first measurement. 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 relatively long but all sentences add value (use case, return fields, partial failure behavior). It is front-loaded with the main purpose.

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 exists, but the description fully explains the return format (summary block fields, per-advisory detail, alternative versions) and error behavior (sources_failed list). This is sufficient for a read-only composite 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% – both parameters are described in the schema. The description only reiterates schema info (scoped packages, version default) without adding new semantic meaning.

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

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

The description clearly states it is a composite check for evaluating npm packages using deps.dev and bundlephobia. It distinguishes itself from sibling tools (e.g., scan_competitor_ai_presence) by focusing on package quality assessment.

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 an agent asks about safety, popularity, size, or cost of adding a package. Notes NPM-only scope and mentions partial failures, but does not exclude specific 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 readOnly, idempotent, and non-destructive behavior. The description adds that it returns specific fields (id, current team, etc.), which is useful but not critical given 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?

Two sentences with no waste. First sentence states purpose and return, second gives usage guidance. Front-loaded and 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's simplicity and the presence of annotations and an output schema, the description covers the essential: what it searches, what returns, and when to use a sibling. Could mention pagination or match behavior, 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 0%, so description must compensate. It does so by indicating the 'query' parameter is a player name, adding the semantic connection that the schema alone lacks.

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 searches for players by name, using a specific verb and resource. It distinguishes from sibling tools like search_teams and get_player by specifying it's a search by name.

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 guidance to use search_teams first if team IDs are needed, implying context for usage. Lacks explicit alternative comparisons but gives reasonable usage context for a simple search 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 the tool as read-only, idempotent, and non-destructive. The description adds the specific fields returned and hints at follow-up usage, but no additional behavioral traits 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 consists of two concise sentences that pack all essential information without any fluff. It is front-loaded with the core 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?

Given the tool's low complexity (one simple parameter), the description adequately covers the purpose, parameters, and output. It is reasonably complete, though it could mention support for partial matches or empty 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?

With 0% schema description coverage, the description compensates by clarifying that the 'query' parameter is the team name. This adds essential meaning beyond the schema's bare type definition.

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

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

The description clearly states it searches for sports teams by name and lists the returned fields. It effectively conveys the tool's purpose, though it does not explicitly distinguish from sibling tools like 'get_team' or 'search_players'.

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 hints at usage by mentioning the returned team ID can be used with other tools, but it does not provide explicit when-to-use or when-not-to-use guidance compared 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 provide readOnlyHint etc. Description adds significant behavioral details: character offsets, similarity scores, truncation at 200K chars with flag, embedding model, window size. 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?

Two well-structured paragraphs, front-loaded with main purpose. Every sentence adds value; no redundant or vague statements.

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

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

Despite no output schema, description explains return format (top-N passages with offsets and scores) and truncation behavior. All relevant aspects covered for a search tool.

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

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

Schema coverage is 100% with good descriptions. Description further clarifies 'text' max chars, 'query' examples, 'limit' default. Adds practical guidance 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 'Semantic search INSIDE a fetched record' with specific verb and resource. Examples (SEC 10-K, article) and differentiation from sibling ask_pipeworx_grounded make 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?

Explicitly says 'Use when the record is too big to cram into the prompt', describes pairing with ask_pipeworx_grounded, and explains trade-offs (saves context, returns only relevant passages).

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

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

The description adds substantial behavioral context beyond annotations: OAuth requirement, delivery channel details (SMS cap, phone verification, webhook signing), and that anonymous users cannot persist subscriptions. No contradictions with annotations.

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

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

The description is well-structured with the purpose first, then types, then delivery. It is somewhat lengthy but each sentence adds value. Slightly verbose but still 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 description covers the return value, subscription types, parameters, and delivery channels. It lacks explanation of what to do with the subscription ID (e.g., for unsubscribing) but sibling tools cover that. No output schema, so return value details are 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?

The input schema has 100% coverage, but the description greatly expands on each parameter with concrete examples and edge-case details (e.g., sponsor or condition required for clinical_trial, webhook signing secret).

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 creates a proactive monitoring subscription to a live-data event stream and returns a new subscription ID. It distinguishes from sibling tools 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?

The description explains when to use the tool for live-data monitoring and provides type-specific examples. However, it does not explicitly contrast with alternatives like recent_alerts or when not to use it beyond noting the OAuth requirement.

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 that the output includes categorized examples with exact tool invocation details, and that it's 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?

Single paragraph is efficient, uses slashes for variants, front-loads the purpose. Could be slightly more structured but remains concise and clear.

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 explains return type (category-bucketed example questions with tool shapes). Covers purpose, parameter behavior, and use cases. Comprehensive for an exploration-oriented 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 optional parameter. Description adds value by listing example topic values ('finance', 'pharma', etc.) and explaining effect of omission (full spread vs focused).

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 uses specific verbs ('returns category-bucketed example questions') and identifies the resource (example questions with tool+argument shapes). It distinguishes from sibling tools like ask_pipeworx by stating to use this first when unfamiliar with 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 tells when to use: 'when you do not yet know what Pipeworx can do for you, or to learn how to call the meta-tools'. Mentions optional topic filtering. Could improve by noting 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?

Annotations already indicate a safe, read-only, idempotent operation. The description adds behavioral details beyond annotations: it specifies the limit of 5 events and the exact fields returned, which helps the agent understand the scope and structure of the response.

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, efficient sentence that front-loads the core purpose and lists outputs without extraneous words. Every part is valuable.

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 (1 parameter), the presence of an output schema, and the annotations, the description provides adequate context. It covers the essential input and output details. No missing information is critical for correct invocation.

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 0%, so the description must compensate. It does so by stating that the tool fetches events 'for a team by team_id', providing context for the single required parameter. However, it does not explain the format or source of the team_id, leaving some ambiguity.

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 fetches the 5 most recently completed games/matches for a team by team_id and lists the specific fields returned (event name, date, home/away teams, final score). This distinguishes it from the sibling tool 'team_events_next' which would fetch upcoming events.

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 implies usage when a team_id is known and recent completed events are needed, but it does not explicitly state when to use versus alternatives like 'team_events_next' or 'get_team'. No exclusions or prerequisites are provided.

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, idempotent, openWorld, non-destructive. Description adds return field list but no further behavioral traits 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?

Single, well-structured sentence conveying essential info. 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?

Output schema presumably covers return structure. Description covers purpose and parameter adequately. Could mention behavior when fewer than 5 events exist, but not critical.

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

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

Only parameter 'team_id' has no schema description (0% coverage). Description merely states 'by team_id' without adding format, source, or constraints.

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?

Clear verb 'Fetch', specific resource 'next 5 upcoming scheduled games/matches for a team', and explicit return fields. Distinguishes from sibling 'team_events_last' by temporal direction.

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?

Implied by 'next 5 upcoming' but no explicit when/when-not or mention of alternatives. Sibling name provides clue but description itself lacks 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?

Discloses that the row is deactivated (not deleted) and historical events remain via 'recent_alerts'. The annotations indicate non-readonly and non-destructive; description adds value by clarifying the deactivation behavior and ownership enforcement.

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 purpose, and critical details (ownership, deactivation) provided concisely.

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 single-parameter tool with no output schema, the description fully covers the action, constraints, and side effects. No gaps remain for effective agent usage.

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

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

Schema coverage is 100% with a clear parameter description. The description adds no additional meaning beyond what the schema provides ('Subscription id returned by subscribe').

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 'Cancel a subscription by id' uses a specific verb ('Cancel') and resource ('subscription by id'), clearly distinguishing it from siblings like 'subscribe' 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?

Describes ownership enforcement ('you can only cancel your own subscriptions') and outcome ('row is deactivated, not deleted'), but does not explicitly contrast with alternatives like 'list_subscriptions' or 'subscribe'.

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?

Even though annotations already mark this as read-only, idempotent, and non-destructive, the description adds substantial behavioral context: it enumerates all six possible verdicts, explains the crucial distinction between could_not_verify and unsupported, warns that could_not_verify must not be treated as evidence, and discloses the verification_error structure. This goes far beyond the annotations and is critical for correct agent behavior.

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

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

The description is well-structured and front-loaded with the trigger phrases and purpose. It includes an 'IMPORTANT for callers' section and an efficiency statement, all of which are valuable. It's longer than minimal descriptions, but the tool's complexity justifies the length; no sentence is wasted.

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

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

With no output schema, the description carries the full burden of explaining return values. It clearly specifies the verdict values, the actual value with pipeworx:// citation, and reasoning. It also covers edge cases like could_not_verify and unsupported, making the description complete for the tool's complexity and leaving no ambiguity about how to interpret 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%, so the baseline is 3. The description adds meaning by explaining how tolerance_pct interacts with grading (e.g., 'set 1–2 for hallucination detection') and how the claim parameter is used in examples like 'Apple's FY2024 revenue was $400 billion' (the latter also appears in the schema). This is a meaningful enhancement 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's purpose: natural-language claim verification against authoritative sources. It provides specific trigger phrases and example claims, and distinguishes itself from sibling tools like ask_pipeworx by describing the dedicated financial and grounded pipelines. This is a specific verb+resource+scope description, not a tautology.

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

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

The description explicitly says 'Use whenever the agent needs to check whether something a user said is factually correct' and explains the routing logic for financial vs. other claims. It also notes it 'Replaces 4–6 sequential calls,' indicating when it's the consolidated choice. However, it does not name alternative tools or explicitly state when NOT to use it, so it falls short of a perfect 5.

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