Github Repo Commits

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

The annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds only the 'recent commit history' scoping, which is useful but vague; it does not mention limits, auth requirements, or what 'recent' means. It does not contradict the annotations.

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 one tight, front-loaded sentence with no filler. It communicates the core purpose immediately and is an appropriately sized definition for a simple read-only tool.

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?

The tool is simple and has annotations plus an output schema to cover safety and return structure. However, 'recent' is ambiguous, and there is no guidance about usage context or edge cases, leaving minor but real gaps for correct invocation.

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?

Schema description coverage is 0%, so the description must compensate, but it does not explicitly explain 'owner' or 'repo' beyond implying a repository context. The parameter names are conventional, yet the description adds little semantic value for an agent needing to know what values these fields expect.

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 states a specific verb and resource ('Extract committer emails from a repo's recent commit history'), so an agent can tell what the tool does. However, it does not differentiate from the similarly named sibling 'github_commit_emails', leaving some ambiguity about which one to pick.

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?

There is no guidance on when to use this tool versus alternatives such as 'github_commit_emails' or 'github_user_repos'. The description gives no context, prerequisites, or exclusions, so an agent must guess which tool fits the task.

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