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

With no annotations, the description carries the full disclosure burden. It implies a safe read ("Return") and adds a genuinely useful behavioral detail: the plans branch is empty when the repository default applies. It does not state permission requirements, scoping (per project), or whether the mapping can be absent, so disclosure is partial.

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, leading with the verb and then the enumerated return values. The parenthetical about empty branch values is the only nuance and it earns its place, though the dense enumeration makes it slightly list-like.

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?

There is no output schema, so the description must convey return content, and it does so by naming each field returned. Combined with zero input parameters, this is nearly complete; only the shape/nesting of the response and the absence case are left unspecified.

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 takes zero parameters, so there are no parameter semantics to document; the baseline for a 0-param tool is 4. The description correctly avoids inventing parameter detail.

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 clear verb+resource ("Return git provider, repository, mapped plans/tests folder paths, and plans branch") and even enumerates the returned fields, so the agent knows exactly what this yields. It doesn't differentiate itself from the sibling update-git-folder-mapping or explain the read vs. write relationship. Still, the purpose itself is unambiguous.

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 when-to-use guidance, prerequisites, or alternative tools are mentioned. An agent is not told to call this before update-git-folder-mapping, or in what workflow context the mapping is needed. Only the implied read semantics suggest usage.

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