appwrite_get_qr_code

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

Annotations are absent, so description carries full burden. It successfully discloses return format ('base64 encoded PNG'), but omits other behavioral traits like idempotency, rate limiting, caching behavior, or whether this requires specific Appwrite permissions/sec Kets.

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 efficient sentences with clear front-loading of action. Front matter '[UNIFIED]' is metadata noise but doesn't significantly impede parsing. No redundant or wasted content.

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 4-parameter utility with no output schema and 0% input schema coverage, the description covers the core function and return format adequately. However, the unexplained 'site' parameter and lack of error handling or constraint documentation leave significant gaps.

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 0% with no parameter descriptions. The description only implies the 'text' parameter usage ('any text or URL') but completely fails to explain required parameter 'site' (unclear if site ID, URL, or domain) and optional parameters 'size' and 'margin' (units, constraints). With 0% schema coverage, description compensation is inadequate.

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?

Description uses specific verb 'Generate' with specific resource 'QR code image' and scope 'any text or URL'. It clearly distinguishes from siblings which focus on database, file storage, and user management operations, with no other QR generation tools present.

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?

No explicit guidance on when to use versus alternatives, prerequisites, or conditions. While the tool is functionally distinct from siblings, the description lacks 'when to use' context or workflow integration guidance.

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