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

No annotations are provided, so the description carries the burden of behavioral disclosure. It clearly discloses the exact stripping behavior and the payment requirement (0.025 USDC on Base L2). However, it does not describe side effects, return behavior, or failure modes if payment is invalid.

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?

One concise, front-loaded sentence states the core behavior immediately, with a brief parenthetical cost note. No filler or redundant wording.

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?

The description gives a clear purpose but leaves critical invocation details unspecified: what the payload must contain (e.g., image URL, base64, local path), how the redacted output is returned, and what happens if the payment is missing. With no output schema and only a generic payload schema, an agent cannot confidently call this tool correctly.

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 100%, so the baseline is 3. The description adds the cost amount for paymentSignature but does not clarify the expected structure or contents of the payload string, which the schema leaves generic.

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 states a specific verb ('Strips') and resource ('image files'), and enumerates exact data categories removed: GPS coordinates, camera serial numbers, thumbnail caches, and creator PII. This clearly distinguishes it from sibling tools like extract_exif_geolocation or obfuscate_pii_entities.

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 phrase 'before sending them to third-party vision models' gives a clear workflow context for when to use the tool. It does not explicitly name alternatives or state when not to use it, so it stops short of a 5.

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