Skillfolio

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

Annotations already declare readOnlyHint=true and openWorldHint=false, setting a safe, non-mutating expectation. The description adds the content scope (thesis, features, exclusions) but no further behavioral details like output format or interaction constraints. This is adequate but not rich 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 with a clear lead-in and a colon-separated list of covered topics. No filler 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 zero parameters, no output schema, and strong annotations, the description sufficiently scopes the informational content (thesis, features, what it does not do). It could explicitly state that it returns an overview, but the coverage statement is adequate for a simple about 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 tool has zero parameters, so schema coverage is trivially 100% and no parameter explanation is needed. The description adds no parameter information, but none is required.

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 subject ('What Skillfolio is') and enumerates covered content: product thesis, features, and deliberate exclusions. This clearly differentiates it from siblings get_pricing and how_to_get_started by focusing on the product overview rather than price or onboarding.

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 explicit when-to-use or alternative mentions appear. The phrasing 'What Skillfolio is' implies use for an overview, but it doesn't state when not to use it or direct users to siblings for pricing/steps. Thus, usage guidance is only implied.

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 annotations already declare readOnlyHint=true and openWorldHint=false, so the tool is a safe, closed read operation. The description adds valuable behavioral context by enumerating the content returned (free features and Full Access inclusions), which goes beyond 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?

The description is a single, front-loaded sentence that immediately states the topic and then details the scope. There is no wasted wording, making it highly concise and structured.

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 zero-parameter, read-only tool with no output schema, the description is completely adequate. It tells the user exactly what information they will receive (free vs. paid features), covering all necessary 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?

The tool has zero parameters, so the schema provides no semantics to clarify. The description compensates by explaining the output content, which is the relevant context for a parameterless tool. Baseline 4 applies.

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: explaining Skillfolio pricing, specifically what is free versus what Full Access at $29.99/month includes. It uses specific resource (pricing) and distinct content, differentiating it from sibling tools like about_skillfolio and how_to_get_started.

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 clearly implies that this tool should be used for pricing inquiries, providing context for when to invoke it. However, it does not explicitly exclude alternatives or mention sibling tools, so it stops short of 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 declare readOnlyHint=true and there is no contradiction. The description adds context that the tool provides a guided walkthrough from resume upload to published portfolio, which is useful for understanding its scope. It does not disclose additional behavioral traits beyond the annotation and the guide's coverage.

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, clear sentence that front-loads the tool's purpose and packs essential details (start point, end point, URL pattern) without unnecessary 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 simple informational guide with no parameters and no output schema, the description fully conveys what the tool does and the scope of its guidance. The destination URL format adds a concrete touch, and no gaps are apparent.

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 zero parameters, so there is no parameter burden. The description appropriately focuses on the tool's function rather than parameters, meeting the baseline for zero-parameter tools.

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 step-by-step guide for creating a Skillfolio profile, specifying the start (resume upload) and end (published portfolio URL). It distinguishes itself from sibling tools by focusing on the onboarding process.

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 this is the tool for users wanting to set up a profile by describing the guide's flow. It does not explicitly state when not to use it or name alternatives, but the sibling tools' names (about_skillfolio, get_pricing) suggest they serve different purposes, providing clear context without explicit exclusions.

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