update_qrcode

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

No annotations are provided, so the description carries the full burden for behavioral disclosure. It only says 'update' and mentions renaming/changing table/location, but does not describe side effects, error behavior, whether it performs partial or full update, or any permission requirements. For a mutation tool, this is insufficient.

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 description is a single, clear sentence that front-loads the purpose. Every word earns its place with no redundancy or unnecessary information.

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?

Given the tool has 5 parameters and no output schema, the description is adequate for the main use cases but lacks details on the full effects of the update (e.g., whether it overwrites or merges fields, impact on redirect_url). The sibling tools provide context, but the description itself leaves some gaps in completeness.

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%, so each parameter has a description. The description adds value by summarizing the main use cases (rename, change table/location) which maps to some parameters. However, it does not mention the 'id' parameter (required) or 'redirect_url'. Baseline for 100% coverage is 3, and the description provides marginal added semantic meaning.

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 uses a specific verb 'Update' and resource 'existing QR code', and mentions the key capabilities 'rename it or change its linked table/location', which clearly distinguishes it from sibling tools like create_qrcode, delete_qrcode, get_qrcode, and list_qrcodes.

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 implies usage when an existing QR code needs modification, which is a clear context. However, it does not explicitly state when not to use this tool or mention any prerequisites or alternatives, though the context of sibling tools makes this fairly clear.

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