Gap Analysis

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the scope of analysis (which structural items are checked) but does not disclose additional behavioral traits like how results are presented, whether a missing path causes errors, or performance characteristics. This is adequate but not rich.

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 that lists the detection targets without any wasted words. It is appropriately brief and easy to parse.

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 tool with one parameter and no output schema, the description should explain what the agent receives as a result. It does not mention return format or how to interpret findings. It also lacks usage guidance relative to similar tools. These gaps make it adequate but incomplete for an agent to fully anticipate the tool's behavior.

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 100% and the single parameter 'path' has a clear description ('Absolute path to the repository root'). The tool description adds nothing about the parameter, so the schema carries the full burden. This meets the baseline but does not exceed it.

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 a specific action ('Structural gap detection') and enumerates the concrete items it checks (CI/CD, linter, TypeScript config, README, test scripts). This distinguishes it from sibling diagnostic tools like security_scan or dead_code, and leaves no ambiguity about its scope.

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 provides no guidance on when to use this tool versus alternatives such as verify_all, full_diagnose, or auto_diagnose. It does not state when this tool is preferred or when to avoid it, leaving the agent to infer usage from the name alone.

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