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

Annotations already declare this as read-only, idempotent, open-world, and non-destructive, so the safety profile is covered. The description adds the scope ('actual stored original') and a behavioral requirement to preserve exact returned values, which is useful but does not disclose additional behavior like response format or edge-case handling.

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?

Three short sentences, front-loaded with the core action. Every sentence earns its place, and there is no redundant repetition of the schema or annotations.

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?

With no output schema, the description should explain what 'supported editable targets', 'locations', and 'expectedText' actually are, but it does not. The instructions assume domain knowledge that the agent may not have, and the tool's role relative to related read tools is left underspecified.

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 only 50%: projectId has a meaningful explanation, but fileId has none beyond format constraints. The description does not clarify either parameter or explain the relationship between the returned 'locations'/'expectedText' and the inputs, leaving a real semantic gap.

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 ('Inspect') and resource ('supported editable targets in the actual stored original'), making the core purpose recognizable. However, it doesn't explicitly differentiate from the many sibling read/inspect tools, so the agent must infer why this one is distinct.

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 gives post-call handling instructions ('Preserve returned locations and expectedText exactly') but provides no guidance on when to choose this tool over alternatives such as helvabase_read_original_page or helvabase_read_source_original. There are no explicit when-to-use or when-not-to-use conditions.

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