add_inline_pr_comment

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

The description adds minimal behavioral insight beyond the annotations. While annotations indicate a non-destructive write operation, the description does not disclose critical behaviors like whether a pending review is required, whether the comment modifies existing review state, or what happens if the line does not exist. Despite sparse annotations, the description does not fill the gap.

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, concise sentence that is front-loaded with the key action. It contains no unnecessary words. However, it could be slightly more structured by separating the location specificity or adding a follow-up sentence for context.

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 6 required parameters and a non-trivial mutation operation, the description is insufficient. It does not explain important constraints (e.g., line must be in diff, PR must be open, user must have write access). Although an output schema exists (not shown), the description should still provide usage context for agents.

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?

With 0% schema description coverage and no parameter explanations in the description, the agent must rely solely on parameter names. The description does not add meaning beyond what is evident from the names (e.g., 'path' and 'line' are clear but 'comment_body' could be ambiguous). No type constraints, format hints, or relationships are clarified.

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 specific action: 'Adds an inline review comment to a specific line in a file within a PR.' It uses a specific verb and resource, and distinguishes the tool from its sibling 'add_pr_comments' which likely adds general (non-inline) comments.

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 guidelines are provided on when to use this tool versus alternatives. There is no mention of prerequisites, such as the need for an existing review, or when it should not be used (e.g., if the file is not part of the diff). The description is silent on usage context.

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