get_nostr_identity

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

The description adds the behavioral trait of requiring the agent key, which is not in annotations (none provided). It clarifies this is a read operation without side effects.

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 sentences, each adding essential information: purpose and a key requirement. No filler, perfectly concise.

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 no parameters and no output schema, the description covers what it returns (public key and npub) and the prerequisite. Complete for the tool's simplicity.

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?

Input schema is empty (0 parameters). Baseline is 4 as per guidelines; description adds no extra parameter info, which is acceptable.

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 it gets the agent's Nostr public key and npub, which is a specific verb+resource pair. It distinguishes from siblings like set_nostr_identity and nostr_zap.

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?

Explicit requirement 'REQUIRES AGENT KEY' provides clear context for when to use. No explicit mention of alternatives, but the requirement is a strong guideline.

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