add_inline_pr_comment

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

Annotations already indicate the tool is not read-only and not destructive; the description adds the specific behavioral detail that it creates an inline comment on a line, but does not disclose side effects like notifications or permissions.

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, front-loaded sentence of 15 words with no unnecessary information, earning its place efficiently.

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?

Despite having an output schema, the description fails to explain return values or behavior for invalid inputs. For a mutable tool with 6 required parameters and no parameter descriptions, additional context is needed for proper agent usage.

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, the description provides no additional meaning for any of the 6 parameters. While parameter names like 'line', 'path', and 'comment_body' are somewhat self-explanatory, there is no guidance on format (e.g., markdown for comment_body) or constraints (e.g., valid line numbers).

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 specifies the verb 'adds', the resource 'inline review comment', and the context 'to a specific line in a file within a PR', which distinguishes it from the sibling tool 'add_pr_comments' that likely adds general PR 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?

The description implies usage when needing to comment on a specific line in a PR file, but does not explicitly state when to use this tool versus alternatives like 'add_pr_comments' for general comments, nor does it mention prerequisites or exclusions.

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