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

With no annotations provided, the description carries full burden for behavioral disclosure. It states this is a deployment operation (implying a write/mutation) and mentions return values, but doesn't cover critical aspects like authentication requirements, rate limits, error conditions, whether deployment is reversible, or what happens to existing deployments. For a mutation tool with zero annotation coverage, this leaves significant gaps.

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 appropriately concise with two sentences: one stating the action and one stating the return values. It's front-loaded with the core purpose. While efficient, it could be slightly more structured by separating usage guidance from return 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?

For a deployment/mutation tool with no annotations and no output schema, the description is incomplete. It doesn't explain what 'deploy' entails operationally, what permissions are needed, how deployments are managed, or what the return metadata includes. The mention of return values is helpful but insufficient given the tool's complexity and lack of structured documentation.

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 description coverage is 100%, so the schema already fully documents the single parameter. The description adds marginal value by reinforcing that it accepts 'built frontend folder (or zip file)' but doesn't provide additional syntax, format details, or constraints beyond what's in the schema. Baseline 3 is appropriate when schema does the heavy lifting.

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 ('Deploy'), the resource ('built frontend directory (or zip file)'), and the target ('EdgeOne Pages'). It distinguishes from the sibling tool 'deploy_html' by specifying it handles directories/zip files rather than HTML content. However, it doesn't explicitly contrast with the sibling, keeping it at a 4 rather than a 5.

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 no guidance on when to use this tool versus alternatives like 'deploy_html'. It mentions the return values but doesn't explain prerequisites, constraints, or appropriate contexts for deployment. There's no explicit when/when-not usage advice.

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?

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool deploys HTML content and returns a public URL, but does not cover critical aspects like authentication requirements, rate limits, whether the deployment is permanent or temporary, error handling, or what happens to previous deployments. This leaves significant gaps in understanding the tool's 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 a single, efficient sentence that front-loads the key action and outcome without any wasted words. It is appropriately sized for a tool with one parameter and clear functionality, making it easy for an agent to parse quickly.

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 lack of annotations and output schema, the description is incomplete for a deployment tool. It does not explain the return value format beyond 'public URL', nor does it address potential errors, side effects, or integration details. For a tool that modifies external resources, more context is needed to ensure safe and correct 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?

The input schema has 100% description coverage, with the parameter 'value' clearly documented as 'full HTML markup' for publishing. The description adds no additional parameter semantics beyond what the schema provides, so it meets the baseline of 3 for adequate but not enhanced 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?

The description clearly states the action ('Deploy HTML content') and target resource ('to EdgeOne Pages'), with a specific outcome ('return the public URL'). It distinguishes from the sibling tool 'deploy_folder_or_zip' by specifying HTML content deployment rather than folder/zip deployment, though it could be more explicit about the distinction.

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 no guidance on when to use this tool versus the sibling 'deploy_folder_or_zip' or other alternatives. It mentions the outcome but lacks context about prerequisites, limitations, or typical use cases, leaving the agent without explicit usage instructions.

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