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

With no annotations, the description carries the full burden. It hints at the resolution mechanism ('URL template and per-branch overrides'), which is useful behavioral context, but it omits auth requirements, what happens when a branch has no override, and whether a default/template fallback is returned.

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?

A single front-loaded sentence with no filler; the core verb and resource lead. It is efficient, though the parenthetical could have been spent on parameter or fallback detail rather than restating the override concept.

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 one-parameter read tool with no output schema, the description conveys what is resolved and the override/template concept. It still leaves gaps on return format and no-override behavior, but is minimally adequate given the tool's simplicity.

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?

One parameter (branchName) with 0% schema description coverage, so the description must compensate. The phrase 'for a Git branch' only loosely maps to branchName and gives no format guidance (branch vs ref, full name, etc.), leaving the single parameter weakly documented.

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?

States a specific verb ('Resolve') and a precise resource ('BASE_URL for a Git branch') plus the source system (TestChimp Branch Management), so the agent knows exactly what it retrieves. It does not explicitly distinguish itself from the many get-* siblings, but the resource is distinctive enough to be identifiable.

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 the tool is for resolving a branch's endpoint URL but gives no explicit when-to-use guidance, no prerequisites, and no mention of alternatives (e.g. get-eaas-config or get-git-folder-mapping). The agent must infer the trigger condition.

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