pull_latest

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

No annotations are provided, so the description carries full responsibility for disclosing behavioral impact. Saying 'Run git pull' implies a mutating operation but does not mention potential side effects (e.g., local changes, merge conflicts, network requirements) or that the working directory may be updated. This is insufficient for a state-changing 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 a single short sentence that delivers the essential information without any fluff. It is front-loaded and every word earns its place.

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 tool with one parameter, the description is minimally viable. It correctly identifies the operation and context, but given the absence of annotations and output schema, it could be more complete by noting potential failure modes or expectations (e.g., clean working tree). Still adequate for a straightforward command.

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 has one parameter (`repo_path`) with 0% description coverage, and the description does not explain what `repo_path` means or how to format it. The name is somewhat self-explanatory, but the description fails to add any semantic value beyond the schema field name.

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 action (run `git pull`) and the target (an already-cloned repo), using a specific verb and resource. It distinguishes itself from sibling tools like `clone_repo` by explicitly scoping to already-cloned repositories.

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 phrase 'already-cloned repo' implies usage when the repository exists locally and needs updates. However, it does not explicitly mention when to use this tool over alternatives, nor does it provide exclusions or prerequisites beyond 'already-cloned.'

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