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

Annotations declare safe, idempotent, read-only behavior. The description adds valuable behavioral context: cost implications of Anthropic probing (BYO key, direct payment), default free model, and a description of the return structure (per-model score, confidence, signals, raw_response). No contradiction with annotations.

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

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

Two sentences with no wasted words. The first sentence clearly states the primary action and output; the second adds default behavior, optional extension, and example use cases. Well-structured and front-loaded.

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

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

Given the tool's complexity (4 parameters, no output schema, annotations present), the description fully explains the purpose, parameters, model choices, and return format. It provides all necessary information for correct invocation without needing additional context.

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

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

Description clearly states it is a composite check for adding an npm package, covering license, advisories, bundle size, etc. It distinguishes well from sibling tools by being specific to npm dependency scanning.

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 when to use: when an agent asks 'is X safe/popular/small' or 'what does adding lodash cost me'. Also notes NPM-only and alternative for other ecosystems.

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 algorithm details (BGE-base-en embeddings, cosine, 500-char windows), input cap (200K chars with truncation flag), and output features (character offsets, similarity scores). Annotations already indicate read-only and non-destructive, description adds substantive context.

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

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

Four sentences front-loaded with core purpose, no fluff, every sentence adds 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?

Covers input, output, limitations, algorithm, and tying to sibling tool. Despite no output schema, description sufficiently explains return values.

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

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

Schema has 100% coverage with descriptions. Description adds examples for query (e.g., 'supply-chain risk'), clarifies text is the already-fetched record, and explains the output structure beyond schema.

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

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

The description clearly states the tool does semantic search inside a fetched record, using verbs like 'search' and 'returns', and distinguishes it from siblings by mentioning pairing with ask_pipeworx_grounded.

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 when to use: when the record is too big for the prompt, and mentions alternative: ground over relevant passages instead of whole document with ask_pipeworx_grounded.

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

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

Annotations provide basic hints (readOnlyHint=false, destructiveHint=false, idempotentHint=true, openWorldHint=true). The description adds significant behavioral context: returns new subscription id, requires OAuth, delivery constraints (10 SMS/day, webhook auto-disable, signing secret one-time return), and type-specific examples. 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 fairly long but well-structured with clear sections (requirements, supported types, delivery channels). It front-loads the core purpose and uses bullet-like formatting. While slightly verbose, every sentence adds necessary detail given the tool's complexity.

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

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

For a tool with 3 parameters (type, params, delivery), nested objects, no output schema, and complex conditional logic, the description covers all essential aspects: requirements, type-specific param structures, delivery options with constraints, and behavior. It is fully self-contained.

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 substantial meaning: explains each type-specific params with real-world examples (e.g., sec_8k with items codes, polymarket_edge with topics), delivery channel constraints and verification requirements. This goes well 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 explicitly states 'Create a proactive monitoring subscription to a live-data event stream' with specific verb ('Create') and resource ('subscription'). It distinguishes from siblings like list_subscriptions, unsubscribe, recent_alerts by focusing on creation.

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

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

The description clarifies when to use by detailing supported subscription types and delivery channels, and mentions prerequisites (Pipeworx OAuth account). It does not explicitly state when not to use, but context is sufficient.

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, openWorldHint, idempotentHint, and destructiveHint. The description adds valuable behavioral context: it returns example questions with exact tool+argument shapes drawn from the live catalog. 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 comprehensive but a bit long. It front-loads key phrases and uses structured lists. Every sentence adds value, though some redundancy exists ('what can I ask'). Still, it is 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 the simple resource (one optional parameter), rich annotations, and no output schema, the description fully covers what the tool does, when to use it, and what it returns. No gaps.

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

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

Schema coverage is 100% for the single parameter. The description adds examples of topic values and explains that omitting it gives a full spread, providing more context than the schema alone.

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 an onboarding entry point that returns category-bucketed example questions. It uses specific verbs like 'returns' and 'Call', and the purpose is distinct from siblings such as discover_tools or ask_pipeworx.

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

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

Explicitly states to use this 'FIRST when you do not yet know what Pipeworx can do' and gives guidance on using the topic parameter to focus. It does not explicitly say when not to use it, but the context is clear enough for an agent.

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

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

Description adds important context beyond annotations: that the row is deactivated (not deleted) and historical events remain available via recent_alerts. Annotations already indicate non-destructive (destructiveHint=false) behavior, but description enriches understanding. 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?

Two concise sentences, purpose front-loaded. 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 tool with one parameter and no output schema, the description covers behavioral aspects (ownership, deactivation) and usage context. Slightly more completeness could be achieved but is adequate.

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

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

Schema coverage is 100% with a clear description for the single parameter 'id'. Description mentions 'by id' but does not add significant new information beyond the schema. Acceptable given high schema coverage.

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

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

Description clearly states 'Cancel a subscription by id' with a specific verb and resource. It distinguishes itself from sibling tools like 'subscribe' and 'list_subscriptions' by being the inverse operation.

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

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

Explicitly states ownership enforcement ('you can only cancel your own subscriptions') and describes the deactivation behavior. While no explicit alternative is given, the context is clear.

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

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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true. Description adds behavioral context: claim verification process (parsing, entity resolution, data lookup, comparison), fallback mechanism, and return values (verdict, actual value with citation, reasoning). 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?

Description is moderately long but well-structured. It front-loads with intuitive natural-language triggers, then explains process and return values. Each sentence adds value; however, could be slightly tightened by removing minor 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?

Given the tool's complexity (dual paths for financial vs. other claims), the description thoroughly covers all aspects: when to use, how it works, return values, and edge cases. No output schema, but return fields are adequately described. Sibling tools are unrelated, so no missing context.

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

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

Input schema has 100% description coverage, providing clear definitions. Description adds semantic value by explaining the default tolerance behavior (implied by wording, capped at 5%) and providing concrete examples for both parameters. This exceeds the baseline of 3.

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 specifies the verb 'validate' and resource 'claim' with natural-language examples. It clearly distinguishes from sibling tools by describing its unique claim verification capability and replaces 4-6 sequential calls, making the purpose highly specific.

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

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

Explicitly states when to use: 'whenever the agent needs to check whether something a user said is factually correct.' It differentiates between financial claims (SEC EDGAR path) and other claims (grounded pipeline), providing clear context and alternatives.

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