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 effectively adds value by specifying the return type ('Certificate details with confirmation of upload') and listing common errors that reveal constraints like format requirements, expiration checks, duplication handling, and store type validation. This provides useful context beyond basic functionality, though it could be more comprehensive about side effects or permissions.

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 ('RETURNS' and 'COMMON ERRORS') and front-loaded key information. It's appropriately sized, with no redundant sentences, though the error list is detailed but necessary for clarity. A minor improvement could be integrating the sections more seamlessly.

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 (uploading certificates with security implications), no annotations, and no output schema, the description does a good job of covering essential aspects: purpose, return values, and common errors. It compensates well for the lack of structured fields, though it could be more complete by mentioning authentication requirements or rate limits.

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 schema description coverage is 100%, so the schema already documents all parameters thoroughly. The description doesn't add any parameter-specific information beyond what's in the schema, such as explaining interactions between parameters or providing examples. However, the 'COMMON ERRORS' section implicitly clarifies parameter constraints (e.g., 'data' must be base64-encoded), which offers some additional context.

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: 'Upload SSL/TLS certificates for secure connections.' This specifies the verb ('upload') and resource ('SSL/TLS certificates') with context about their purpose ('for secure connections'). However, it doesn't explicitly differentiate from its sibling 'read_certificates' beyond the obvious upload vs. read distinction, which is why it doesn't reach 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. It doesn't mention prerequisites, such as needing specific permissions or workspace access, or compare it to sibling tools like 'write_connections' or 'write_workspaces' that might handle related operations. The 'COMMON ERRORS' section hints at usage constraints but doesn't explicitly state when to use the tool.

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