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

With no annotations provided, the description carries the full burden. It explains what the tool does (runs compiler and schema verification) and the scope (across all files impacted by a change), but it does not disclose behavioral traits such as whether it modifies files, requires specific permissions, has side effects, or what the output schema represents. This is adequate but not exceptional.

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, clear sentence that efficiently conveys the tool's purpose without unnecessary words. It is front-loaded and earns its place.

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 the tool has two optional parameters and an output schema, the description provides a solid overview of the tool's function. It could benefit from noting that both parameters are optional, but the context signals help there. The description is complete enough for an agent to understand the tool's core purpose and scope.

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 description coverage is 0%, so the description must compensate for the two parameters. It does not explain the meaning of 'repo_path' or 'modified_files' beyond their names in the schema. However, the description of the tool's action (running verification across impacted files) gives implicit context that 'modified_files' likely lists changed files and 'repo_path' is the repository root. This is minimal value added.

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 verb 'Runs' and the resource 'compiler and schema verification across all files impacted by a change', which is specific and distinguishes it from siblings like 'verify_schema_change' (which focuses only on schema) and 'get_stack_health' (which checks overall health).

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 a change has been made and needs verification, but it does not explicitly state when to use this tool versus alternatives like 'verify_schema_change' or 'trace_fullstack_path', nor does it mention when not to use it or any prerequisites.

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