gitPullRepo

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action ('Pulls changes') but doesn't clarify whether this is a read-only operation, what happens on failure, if it requires authentication, or any side effects. This is insufficient for a mutation-like tool with zero annotation coverage.

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, efficient sentence that directly states the tool's purpose without unnecessary words. It's front-loaded and wastes no space, making it easy to parse quickly.

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?

Given the complexity of a Git operation with 5 parameters, no annotations, and no output schema, the description is incomplete. It doesn't explain what 'Pulls changes' entails (e.g., merging, fetching), error handling, or return values, leaving significant gaps for the agent to operate effectively.

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 description coverage is 100%, so the schema already documents all 5 parameters (repoId, branch, transport, user, password) with descriptions. The description adds no additional meaning beyond the schema, such as explaining parameter interactions or default behaviors, which aligns with the baseline score when schema does the heavy lifting.

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 ('Pulls changes') and resource ('from a Git repository'), making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'pushRepo' or 'gitRepos', which would require mentioning specific scope or constraints.

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 provides no guidance on when to use this tool versus alternatives like 'pushRepo' or 'gitCreateRepo'. It lacks context about prerequisites (e.g., repository setup) or typical scenarios, leaving the agent to infer usage from the tool name alone.

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