git_commit

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

With no annotations, the description carries the full burden and delivers almost nothing: it does not say the commit is local until git_push, whether hooks run, whether it can fail on an empty index, or what the response contains. The only behavioral clue is the 'staged' scope constraint.

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?

Three words with no waste, but the brevity comes from under-specification rather than tight editing. It is front-loaded and scannable, yet there is no second sentence earning its place because there is no second sentence at all.

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 one-parameter mutation tool the description is too thin: no annotations, no output schema, and no mention of the git_add → git_commit → git_push sequence the sibling list implies. An agent can guess the call, but not the preconditions or consequences.

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 coverage is 100% with a single, self-explanatory 'message' parameter, so the schema already does the work. The description adds nothing about message format or conventions, which is acceptable at this baseline.

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 specific verb+resource ('Commit staged changes'), and the word 'staged' separates it reasonably well from siblings like git_add and git_push. However, it never names or contrasts with those siblings, so the agent must infer the handoff chain from names alone.

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 and no prerequisites: it does not say that changes must be staged with git_add first, nor when to prefer git_commit over git_push or git_status. The 'staged' qualifier hints at a precondition but leaves it implicit.

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