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

Annotations already cover the safety profile (read-only, idempotent, non-destructive), and the description adds ordering ('newest first') and the per-commit payload shape, including agent provenance fields set when an AI agent made the change. That is useful context an agent cannot get from the annotations alone.

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?

Two short sentences, front-loaded with the purpose and then the ordering/payload detail. Only the '(D112)' spec reference is dispensable, which is a minor waste.

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 four-parameter read tool with no output schema, the description covers the return shape and ordering well. Pagination mechanics are left to the schema's cursor field, which is acceptable, but the default page size and what an empty result looks like are not addressed.

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 75% and the path parameter already carries a long, detailed description in the schema, so the description's 'optionally for one path' adds little. The limit and cursor parameters are not discussed at all in the description.

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 ('Commit log of the project'), and the optional path scope makes the tool's shape immediately clear. It does not explicitly differentiate from get_doc_history or diff, so it stops short of 5.

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 statement of when to use this versus alternatives. 'Optionally for one path' implies filtering, but a reader must infer the split between get_history, get_doc_history, and diff entirely on their own.

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