tascan_register_tag

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

Annotations already indicate this is a non-read-only, non-destructive, non-idempotent write operation. The description adds useful behavioral context: the routing effect when tapped and the hardware chip requirement (NTAG215, NFC Tools Pro). However, it does not disclose what happens on duplicate registration, validation checks, or whether the operation is reversible.

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 extremely concise at two sentences. The first sentence contains the core purpose ('register a physical NFC tag to a project, task list, or specific task'), and the second adds value by explaining the tapping behavior and hardware requirements. There is no 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?

For a tool with 7 parameters and no output schema, the description lacks important context: it does not explain what the tool returns (e.g., success status, created registration ID), how to obtain the tag_hardware_id, or whether duplicate hardware IDs are handled. The schema descriptions cover individual parameters, but the overall workflow and error conditions are missing.

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 input schema already has 100% description coverage, with clear parameter descriptions for all 7 properties. The tool description does not provide additional meaning for any specific parameter beyond what the schema already contains, so it meets the baseline for a high-coverage schema.

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 states the action: 'Register a physical NFC tag to a project, task list, or specific task.' It also explains the resulting behavior ('When someone taps the tag, TaScan routes them to the linked resource') and mentions hardware specifics. This distinguishes it from sibling tools like tascan_list_tags.

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 provides no explicit guidance on when to use this tool versus alternatives, nor does it mention prerequisites or exclusions. The only implicit context is that it is for physical NFC tag registration, but no differentiation from other Tag-related tools (e.g., no 'Use this for new tag registrations only' or 'Do not use if the tag is already registered').

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