Schema coverage is 100% with a clear description for the sole parameter. Description does not add additional meaning 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?

Clearly states the tool lists the caller's active subscriptions and specifies returned fields. Distinguishes from sibling tools subscribe 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?

States exactly when to use: to review monitored subscriptions before adding more or to find an ID for cancellation. Implicitly suggests not using it for other purposes.

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 the annotations: rate-limited to 5 per identifier per day, free and does not count against quota, team reads digests daily, and signal affects roadmap. It also warns not to paste the end-user's prompt and to describe issues in terms of Pipeworx tools/packs, which shapes 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 longer than ideal, but every sentence earns its place: use cases, exclusions, formatting guidance, rate limit, and effects. It is front-loaded with the core purpose, then organized logically. Minor redundancy ('ONLY for tools served by this Pipeworx connection' appears twice in spirit) prevents 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 moderate complexity and lack of output schema, the description covers all necessary aspects: when to use, what to report, how to format the message, constraints (rate limit), and consequences (roadmap impact). The optional context object is also addressed indirectly through the emphasis on specifying tools/packs. This is complete.

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

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

Schema coverage is 100%, so the baseline is 3. The description adds extra meaning by dictating how to phrase the message ('Describe the issue in terms of Pipeworx tools/packs — don't paste the end-user's prompt') and by clarifying what constitutes appropriate feedback for each type, which helps the agent populate parameters correctly beyond the schema's enum literals.

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 ('Tell') and a clear resource (Pipeworx team), then enumerates exactly what kinds of feedback are accepted (broken, missing, needs to exist). It distinguishes this from sibling tools by explicitly scoping it to tools served by this Pipeworx connection, so an agent can tell it apart from ask_pipeworx or other informational 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?

Provides explicit when-to-use criteria: use for bug (wrong/stale data), feature/data_gap (tool you wish existed), or praise. It also gives a strong exclusion rule—if the tool came from a different MCP server, file with that server instead—and offers a decision shortcut for identifying Pipeworx tools. This is exceptionally clear.

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

Schema coverage is 100%, so baseline 3. Description adds minor nuance (scoped packages accepted, version defaults to latest) but doesn't significantly extend 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?

Clearly states it's a composite check for npm package feasibility, combining deps.dev and bundlephobia data. Specific verb and resource, distinct from sibling 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?

Explicitly says when to use (agent questions about safety/popularity/size), and notes limitations (NPM only, alternatives 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 declare readOnlyHint, openWorldHint, idempotentHint, destructiveHint. Description adds technical details: BGE-base-en embeddings, cosine similarity, 500-char overlapping windows, 200K char cap with truncation flagging. This goes well beyond annotation information.

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, well-structured: purpose first, then usage guidance, pairing, and technical details. Every sentence adds value, no fluff. Front-loaded with key 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?

Despite no output schema, the description explains return format (passages with character offsets and similarity scores), technical constraints (embedding model, window size, char cap), and integration with sibling tools. Sufficient for an agent to understand and invoke correctly.

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. The description reinforces parameter usage: 'pass the text you already pulled' for text, 'natural-language query' for query, and implies limit via 'top-N passages'. It adds real-world context but doesn't deeply extend 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 'Semantic search INSIDE a fetched record' and explains the core function: pass text and query, get back top-N passages with offsets and scores. It distinguishes itself from sibling tools by focusing on searching within already-fetched content, contrasting with 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?

Explicitly states when to use: 'Use when the record is too big to cram into the prompt — search_within saves context, returns only the passages that matter.' Also pairs with ask_pipeworx_grounded for a recommended workflow. No explicit when-not-to-use, but the 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?

Adds rich context beyond annotations: account requirement, phone verification, SMS cap (10/day), webhook auto-disable after 10 failures, signing secret handled once. No annotation contradictions found.

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, then requirements, types, delivery. Each sentence adds value; slightly long but no 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?

Covers requirements, all types with examples, delivery channels with caveats, failure modes. No output schema, but return value stated. Complete for a complex 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 description adds extra meaning: examples for each type, delivery channel details, and limitations. Provides context 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?

Specific verb+resource: 'Create a proactive monitoring subscription'. Distinguishes from siblings like list_subscriptions and unsubscribe by being the creation tool.

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

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

Clear context: when to use for proactive monitoring, requires Pipeworx OAuth account, supported types. No explicit when-not-to-use but implicit from sibling 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, openWorldHint, idempotentHint as true and destructiveHint as false. The description adds context about returning example questions with tool/argument shapes and the effect of the topic parameter. 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 fairly long but packs essential information efficiently. It front-loads aliases and purpose, but could be slightly more concise. However, no trivial or redundant sentences.

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 explains what is returned (category-bucketed example questions) and covers the single parameter thoroughly. It also provides usage guidance and behavioral context, making it complete for a simple, read-only 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 describes the optional topic parameter with specific values. The description adds meaning by explaining how omitting vs providing topic changes the output, and gives real examples like 'finance', 'pharma', 'betting'.

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: it returns category-bucketed example questions about Pipeworx's capabilities, serving as an onboarding entry point. It distinguishes itself from siblings like discover_tools and ask_pipeworx by its specific role in helping users learn what to ask.

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 the tool: first when you don't know what Pipeworx can do, or to learn how to call meta-tools. It also implies alternatives like ask_pipeworx for actual questions.

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 ownership enforcement and deactivation behavior beyond annotations. No contradiction; annotations align with description.

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 filler; front-loaded with the action and key constraints.

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?

Complete for a simple tool with one parameter and no output schema; addresses persistence of historical data.

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 description does not add new meaning beyond what schema provides 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?

Clearly states the verb 'cancel', the resource 'subscription by id', and includes ownership enforcement and deactivation behavior. Distinguishes from sibling tools 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?

Explicitly states when to use (cancel own subscription) and mentions historical availability via recent_alerts. 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?

Annotations already indicate read-only, open-world, idempotent, non-destructive behavior. The description adds valuable details about the two processing paths, the verdict types, and the inclusion of citations and reasoning. 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 each sentence adds value. It front-loads with example phrases and clearly structures the two processing paths and output 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?

Given the tool's complexity (two paths, verdict types, reasoning), the description covers input semantics, processing logic, output format, and use cases thoroughly. No output schema exists, so the description compensates well.

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. The description adds extra context for 'tolerance_pct', suggesting specific values for hallucination detection, which goes beyond the schema 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 identifies the tool as a claim verification tool with specific verb phrases and examples. It distinguishes itself from siblings by focusing on natural-language claim verification, with a structured path for financial claims and a grounded path for others.

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 'Use whenever the agent needs to check whether something a user said is factually correct.' It provides context for when to use the fast path vs. grounded pipeline, but doesn't explicitly list alternative tools or when not to use it.

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