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

Annotations are absent, so the description carries the full burden of disclosing behavior. The only explicit behavioral hint is 'body discarded,' which says little about side effects, output, permissions, or what 'count' actually produces. For a tool with no annotation safety hints, this is not enough clear behavioral disclosure.

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 compact with no filler words, but it is a cryptic fragment rather than a well-structured sentence. 'body discarded' is attached awkwardly and does not clarify the tool's purpose or invocation; brevity comes at the cost of readability.

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 9 optional parameters, no output schema, and no annotations, the description says too little about how to fill/select parameters or what a successful call returns. The phrase 'body discarded' and the word 'count' hint at behavior, but the overall description is not complete enough for reliable agent selection and 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?

The schema covers all 9 parameters with individual descriptions, so the 100% coverage baseline applies. The description adds essentially no parameter-specific meaning itself, and it does not clarify which optional parameter, if any, should contain the gitignore value or path.

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 names a specific resource ('gitignore negation rules') and an operation ('count'), which gives a basic topic. However, it is a fragment, not a sentence, and never explains what 'ok' in the tool name or the result of the count means. An agent would have to guess whether this returns a number, a boolean, or something else.

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, when-not-to-use, prerequisites, or alternative tool guidance is provided. The intended use is only implied by the resource mentioned in the phrase 'gitignore negation rule count,' with no explanation of how it differs from sibling count/check tools.

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