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

Discloses default model (Workers AI Llama-3.3-70b), optional Anthropic probing with BYO key, cost implications (free vs pay), and return format (per-model score, confidence, signals, raw_response plus combined view). Adds value beyond annotations.

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

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

Two sentences that are front-loaded with the main purpose and output. Every part earns its place; no 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?

Covers return format and model options. No output schema, but description sufficiently explains what is returned. Could add more on rate limits or error handling, but annotations cover safety.

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

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

Schema coverage is 100%, so baseline is 3. Description adds meaning by explaining the default model, clarifying the _apiKey purpose, and giving examples for entity. Provides additional context beyond schema descriptions.

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

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

The description clearly states the tool probes LLMs for knowledge about a business/brand/product/topic and returns a visibility score per model. It distinguishes itself from siblings by focusing on per-model scoring and combined view.

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

The description explains what the tool returns (ranked list with score, confidence, signal density) which compensates for the lack of output schema. It also clarifies it calls ai_visibility_check internally. Could mention potential costs if using anthropic API key, but not essential for 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?

All four parameters are described in the schema (100% coverage). The description adds: first entity treated as subject for narrative, rest as competitors; and clarifies that omitting models defaults to workers-ai. This adds value beyond the schema descriptions.

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

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

The description clearly states the tool compares AI visibility across multiple entities side-by-side using ai_visibility_check, ranks them, and identifies most/least recognized. It distinguishes itself from sibling ai_visibility_check which is for single entities, and from compare_entities which is generic.

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

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

The description mentions it is useful for competitive AI-marketing audits and gives an example use case. It implies single-entity checks should use ai_visibility_check, but does not explicitly state when not to use this tool or list 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 mark it as read-only, idempotent, non-destructive. Description adds valuable behavioral details: composite fan-out, partial failures degrade gracefully, bundlephobia's first measurement can take 5-30s, sources_failed list on timeout. 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 moderately long but front-loaded with core purpose. It uses a clear structure with return fields listed. Could be slightly more concise but no significant 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?

No output schema exists, so description fully explains return values: summary block fields, per-advisory details, links, alternative versions. Also covers ecosystem limitations and failure behavior, making it complete for agent decision-making.

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

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

Schema coverage is 100% with clear descriptions. Description adds clarification that scoped packages (e.g., @types/node) are accepted for the package parameter, which is not in the schema. This adds useful semantic nuance beyond 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 it's a composite check for evaluating npm packages, listing specific data sources (deps.dev, bundlephobia) and return fields. It distinguishes itself from siblings by being focused on npm dependency analysis.

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

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

Explicitly says 'Use whenever an agent asks "is X safe / popular / small" or "what does adding lodash cost me".' Also clarifies ecosystem scope (NPM only in v1, other ecosystems via deps.dev:version).

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, destructiveHint. The description adds valuable behavioral details: embedding model (BGE-base-en), chunking strategy (500-char overlapping windows), character cap (200K chars with truncation and flagging), and the inclusion of offsets for quote verification. 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 concise—three sentences in the core section plus a technical note. It front-loads the key action and pairs with sibling, then adds technical details. Every sentence serves a purpose without 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?

Despite no output schema, the description clearly states what is returned (passages with character offsets and similarity scores). It also explains the internal mechanics (embeddings, chunking, cap) and use-case pairing, making the tool fully understandable.

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 three parameters. The description adds practical examples for the query parameter ('supply-chain risk', 'fiscal year 2024 revenue') and clarifies the text parameter's cap. While schema already does well, the description provides valuable usage 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 that the tool performs semantic search inside a fetched record. It specifies the input (text and query), output (top-N passages with character offsets and similarity scores), and distinguishes itself from the sibling tool 'ask_pipeworx_grounded' by noting that it saves context and returns passages with offsets for verification.

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

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

The description explicitly says when to use the tool: 'when the record is too big to cram into the prompt'. It also explains the benefit ('saves context, returns only the passages that matter') and mentions a companion tool ('Pairs with ask_pipeworx_grounded') for further grounding.

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, and the description adds behavioral details: requires OAuth account, returns subscription ID, stateful persistence, delivery side effects (webhook signing, auto-disable after 10 failures). 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 slightly long but each sentence adds value. It front-loads the main purpose and then logically flows into type details and delivery options. Minor redundancy in delivery descriptions, but overall well-organized.

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 covers return value (subscription ID). It addresses all complexities: multiple types with distinct params, delivery channels with constraints, authentication requirements, and webhook signing. Complete for a creation tool.

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

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

Schema coverage is 100%, but the description adds significant meaning: explains enum values with examples like 'sec_8k items:["5.02"] = officer change', details nested params structure, and delivery channel specifics (webhook signing). This goes beyond the schema descriptions.

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

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

The description states 'Create a proactive monitoring subscription to a live-data event stream' and 'Returns the new subscription id', providing a specific verb and resource. It distinguishes from sibling tools like 'list_subscriptions' and 'unsubscribe' by focusing on creation and monitoring.

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

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

The description explicitly says when to use (proactive monitoring) and when not (anonymous/BYO cannot persist), and provides detailed examples per subscription type. It also covers delivery channel constraints (SMS cap, phone verification) and webhook auto-disable, guiding appropriate usage.

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

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

Annotations already declare readOnly, openWorld, idempotent, and non-destructive behavior. The description adds that results are drawn from a live catalog and are category-bucketed, which is helpful but not essential given the rich 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 dense and front-loaded with user intent, but the long slash-separated list of phrases could be streamlined. Still, every sentence serves a purpose, and the structure is 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?

Despite no output schema, the description fully explains the return value (category-bucketed example questions with tool+argument shapes), the call patterns, and the use case. It leaves no ambiguity about what the tool does and when to use it.

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

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

Schema coverage is 100% and the schema's description already includes the list of topics and the instruction to omit for spread. The tool description repeats this information without adding new semantic value, so the 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 uses multiple user-aligned phrases ('What can I ask Pipeworx?', 'give me ideas', 'getting started') and clearly states the tool returns category-bucketed example questions with tool+argument shapes. It distinguishes itself from sibling tools like ask_pipeworx by positioning as an onboarding entry point.

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 this FIRST when you do not yet know what Pipeworx can do for you' and explains how to call it (no args or with topic). It does not explicitly list when not to use it, but the context clearly separates it from other discovery 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?

The description adds significant behavioral detail beyond annotations: 'The row is deactivated (not deleted) so its historical events stay available via recent_alerts.' It also notes ownership enforcement, which annotations don't cover. 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 extremely concise with two sentences, front-loading the primary purpose. Every sentence adds value without redundancy.

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

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

For a simple 1-parameter mutation tool with no output schema, the description fully explains the effect (deactivation not deletion) and links to relevant sibling tool 'recent_alerts'. Complete and sufficient.

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

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

The schema already provides full coverage (100%) with a description for the 'id' parameter. The description doesn't add new information about the parameter 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 action ('Cancel a subscription') and the method ('by id'). It effectively distinguishes from sibling tools like 'subscribe' and 'list_subscriptions' by specifying the cancellation action.

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 context: 'Ownership is enforced — you can only cancel your own subscriptions.' This tells the agent when to use it (for own subscriptions) but doesn't explicitly mention when not to use or suggest 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 indicate read-only, idempotent, open-world, non-destructive behavior. The description adds context: it uses SEC EDGAR + XBRL, returns a verdict with types (confirmed, approximately_correct, refuted, inconclusive, unsupported), structured form, actual value with citation, and percent delta. This provides extra behavioral detail 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 thorough but somewhat lengthy, with multiple examples and comparisons. It is front-loaded with query phrases, but could be more concise without losing information.

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

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

Given the tool has one parameter and no output schema, the description covers input format, domain limitations, return types, and efficiency gains (replaces multiple sequential calls). It is sufficiently complete for an agent to understand 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 one parameter having a description. The description adds examples and clarifies the natural-language format, which adds meaning 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 clearly states the tool performs natural-language claim verification against authoritative sources, with examples and synonyms. It specifies the domain (company-financial claims for public US companies). However, it does not explicitly differentiate from related siblings like compare_entities or entity_profile, which could handle similar inputs.

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 instructs to use whenever the agent needs to check factual correctness of a user's statement, and states the supported domain. It does not explicitly list when not to use or mention alternatives, but the scope is clearly bounded.

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