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

With no annotations, the description carries the full burden. It discloses that the tool reads from environment variables and explicitly guarantees 'Does not expose tokens or passwords', which is a meaningful security behavior. It doesn't explicitly state 'read-only', but 'Report' implies a non-mutating operation.

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 two sentences, front-loaded with the primary purpose and followed by a necessary security note. Every word earns its place; there is no redundancy or filler.

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 configuration-reporting tool with zero parameters and an output schema, the description covers all essential context: what is reported (host, API URL, auth mode, bind settings), the source (env), and the security exclusion. Nothing critical is missing.

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 and the schema is empty, so there is nothing to explain. The baseline for zero-parameter tools is 4, and the description adds no parameter-specific information because none exist.

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 the specific verb 'Report' and identifies the exact resource (GitLab connection configuration including host, API v4 URL, auth mode, and bind settings). It clearly distinguishes from sibling tools that deal with GitLab data objects like merge requests and projects.

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 gives no explicit 'when to use' or alternative tool guidance. However, the context makes it obvious this is for checking connection configuration, and no sibling tool overlaps. Usage is implied rather than explicitly stated.

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