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

Discloses scanning and extraction activities but does not discuss side effects (e.g., database writes, idempotency), authentication needs, or performance impact. With no annotations, more behavioral detail would be beneficial.

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?

Two sentences with front-loaded purpose. Every phrase contributes: first sentence states action, second details scope. No redundancy.

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?

Covers main action but lacks description of return value/status (no output schema), error conditions, or prerequisites (e.g., UE environment). For a registration tool with 4 parameters, slightly incomplete.

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 description adds limited value beyond schema. It reinforces the tool's purpose but does not provide additional semantic guidance for parameters.

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?

Clearly states the tool registers and indexes a UE codebase, scanning C++ files for symbols, macros, call graphs, and dependencies. Distinguishes from sibling tools which are analysis/query tools, not initialization.

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?

Implied usage as a setup step before analysis tools, but no explicit guidance on when to use (e.g., 'first run') or when not to use (e.g., already indexed). No alternatives mentioned.

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