security_totp_qr_generator

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

No annotations are provided, so the description carries full burden. It states that the tool builds URIs and QR codes and lists compatible apps, but does not disclose behavioral traits such as mutation, authentication needs, or rate limits. The 'Menu ID' mention adds no behavioral insight.

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 concise and includes key elements: purpose, standards, compatibility, and a pointer to more detailed guidance. However, it could be more structured (e.g., separating parameter info) and the 'Menu ID' line adds little value.

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 8 required parameters left unexplained, no output schema, and no annotations, the description is incomplete. It relies on the user calling describe_tool for full guidance, which is insufficient for standalone understanding. The agent lacks the information to correctly invoke the tool.

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 0%, so the description must compensate. It provides no explanation of the 8 required parameters (e.g., operation, type, issuer, account, secret, algorithm, digits, period). The agent cannot infer parameter meanings from the description alone.

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 identifies the tool as a 2FA TOTP QR Generator that builds otpauth:// URIs and QR codes. It specifies RFC standards (6238, 4226) and lists compatible authenticator apps, making its purpose distinct from sibling tools like crypto_password_generator or security_jwt_generator_validator.

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 for generating QR codes for two-factor authentication but lacks explicit guidance on when to use this tool vs alternatives. It mentions using describe_tool for full guidance, which partially compensates, but no direct context on prerequisites or exclusions.

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