Extract Structures Via Decimer Api

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

With no annotations, the description carries the full burden. It discloses a behavioral constraint (the confirm_upload condition) but says nothing about side effects, output format, prerequisites, or reversibility. The upload-only framing is misleading about the actual extraction functionality.

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 single sentence is concise but under-specified. It doesn't front-load essential information about what the tool does or how to use it. The sentence reads like a guardrail instruction, not a tool definition, so it is under-specification rather than effective conciseness.

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 7 parameters, no output schema, and no annotations, this description is grossly incomplete. An agent cannot determine correct usage, expected return, or even the core function. The description provides almost none of the context needed for reliable invocation.

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?

The schema has 0% description coverage for its 7 parameters. The description mentions confirm_upload but adds no semantic meaning beyond its name. It does not explain image_path, hand_drawn, output_path, approved_origin, approved_sha256, or timeout_seconds, nor how they interact. The description fails to compensate for the lack of schema information.

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 names a specific action ('upload an image to DECIMER') and resource, but omits the tool's actual purpose of extracting chemical structures, which is only implied by the name. It also does not differentiate from the sibling 'extract_structures_from_image', leaving purpose ambiguous.

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 only guidance is a conditional caveat ('only when confirm_upload is explicitly true'), which is a parameter precondition rather than a usage guideline. It provides no context on when to choose this tool over alternatives or any exclusions.

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