git_pull

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

No annotations; description mentions the exact git command but fails to disclose potential side effects like merge conflicts or the need for a clean working directory.

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?

Extremely concise with two sentences; no wasted words, directly addresses the tool's action.

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?

Lacks description of return values (output schema absent) and prerequisites (e.g., existence of remote origin), leaving gaps for an agent unfamiliar with git internals.

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?

No parameters in schema, schema coverage is 100%. Description adds nothing about parameters as they are absent, which is acceptable per baseline of 4 for zero params.

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?

Description clearly states the verb 'execute git pull' and specifies the resource 'from origin/main to current branch', distinguishing it from sibling tools like git_push and git_add.

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 explicit guidance on when to use vs alternatives, such as when to pull from other remotes or branches. Implicitly indicates for pulling from origin/main only.

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