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

Implies when to use: for searching datasets by keyword. References related tools (dataset_info, query) for further steps. Does not explicitly state 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?

Adds significant detail beyond annotations: BGE-base-en embeddings, cosine similarity, 500-char overlapping windows, 200K char cap with truncation flagging. All annotations (readOnly, idempotent, openWorld, non-destructive) are consistent and reinforced.

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?

Well-structured with front-loaded purpose, clear examples, and technical details. Every sentence serves a purpose without redundancy. Concise while covering all essential aspects.

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 fully explains return values (passages with character offsets and similarity scores). It also covers edge cases (200K char cap, truncation flagging) and hints at embedding details. 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?

Schema coverage is 100%, but description adds value with concrete examples (SEC 10-K, natural-language query examples). For text and query parameters, it provides usage context beyond schema descriptions. Limit parameter is implied ('top-N') but not explicitly restated.

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 'Semantic search INSIDE a fetched record' with specific examples (SEC 10-K, article, long tool result). It clearly distinguishes the tool's scope as searching within previously fetched content, differentiating it from tools that fetch or search externally.

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

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

Provides clear when-to-use guidance: 'Use when the record is too big to cram into the prompt... saves context, returns only the passages that matter.' Also mentions pairing with ask_pipeworx_grounded. Lacks explicit when-not-to-use or alternatives, but context is strong.

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 contradicts the idempotentHint annotation: it states 'Returns the new subscription id,' implying non-idempotent creation, while idempotentHint=true suggests idempotency. This inconsistency warrants a score of 1. The description otherwise provides rich behavioral context, but the contradiction lowers the score.

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

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

The description is well-structured with clear sections and examples, but it is lengthy. It efficiently conveys necessary information without irrelevant details, earning a score of 4.

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

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

Given the tool's complexity (3 parameters, nested objects, enums, delivery channels), the description is remarkably complete. It covers all relevant aspects: prerequisites, type-specific params, delivery options with constraints, and return value. No output schema exists, but the description adequately explains the return value.

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%, providing a baseline of 3. The description adds substantial meaning by explaining each enum value for type with concrete examples and specific parameter structures, and details delivery options with constraints, significantly 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 clearly states the tool's purpose: 'Create a proactive monitoring subscription to a live-data event stream.' It uses a specific verb and resource, and distinguishes it from siblings like list_subscriptions and recent_alerts.

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 prerequisites (Pipeworx OAuth account) and provides examples for each subscription type with parameters, implying when to use each. However, it lacks explicit 'when not to use' or direct comparisons to sibling tools beyond a brief mention of the feed channel.

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 read-only, idempotent, open-world, non-destructive. The description adds behavioral context: returns live examples from catalog, uses no arguments for full spread, supports topic filtering. 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?

Description is somewhat long but every sentence adds value. It front-loads common user queries and structures content logically. Minor verbosity for readability.

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 fully explains the return structure (category-bucketed examples with tool shapes). Covers all scenarios and is complete for an onboarding tool.

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

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

Schema coverage is 100% and the description goes beyond by explaining the effect of omitting the topic parameter and listing specific allowed values. Provides practical usage 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 the tool returns category-bucketed example questions with tool+argument shapes, serving as the onboarding entry point. It distinguishes from siblings like ask_pipeworx by focusing on exploration.

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 recommends using this tool first when unsure of Pipeworx capabilities, and mentions meta-tools. Provides guidance on when to call without arguments vs with a specific topic.

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 deactivation (not deletion) and that historical events remain available via recent_alerts. Annotations (readOnlyHint=false, destructiveHint=false, idempotentHint=true) already indicate mutation is safe and idempotent; description adds valuable detail without contradiction.

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

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

Two efficient sentences: purpose first, then ownership and behavioral detail. No filler, 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?

For a single-parameter tool with no output schema, the description covers purpose, ownership, and side effects completely, referencing relevant sibling tool (recent_alerts).

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 'id' is fully described in schema (100% coverage). Description adds no additional meaning beyond stating 'by id' and referencing subscribe, which is already in 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?

Clear verb 'Cancel' and resource 'subscription by id'. Distinguishes from sibling tools like 'subscribe' and 'list_subscriptions' by specifying ownership and deactivation behavior.

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, guiding when to use: only for own subscriptions. No when-not-to-use or explicit alternatives mentioned, 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 declare readOnlyHint, openWorldHint, idempotentHint, destructiveHint. Description adds significant context: two verification pipelines (SEC EDGAR + XBRL for financial claims, grounded pipeline for others), exact percent-delta math, return format (verdict, value with citation, reasoning). 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?

Single dense paragraph with clear structure: examples, scope, pipeline description, return values. Slightly lengthy but every sentence adds value. Could benefit from bullet points but not necessary.

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 fully covers return values: verdict types, actual value with citation, reasoning. Handles both claim types. No gaps remain for an AI agent to understand usage and expectations.

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 provides descriptions for both parameters. Description adds value: explains tolerance_pct overrides implied tolerance, gives example use (1-2 for hallucination detection), and for claim provides realistic input examples. Enriches schema 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?

Description explicitly states 'natural-language claim verification against authoritative sources' and provides concrete example queries. It distinguishes between company-financial and other claims, clarifying scope and contrasting with sibling tools by mentioning it replaces 4-6 sequential calls.

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?

Clearly states 'Use whenever the agent needs to check whether something a user said is factually correct.' Implicitly excludes non-factual queries, and contrasts with siblings by describing its unique pipeline. Lacks explicit when-not-to-use, but overall guidance is strong.

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