get_pairing_secret

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

With no annotations provided, the description carries the full burden of behavioral disclosure, and it does so thoroughly. It states that the secret is generated on first call, the same value is returned on every later call, and the server never sees the value. This gives an agent a clear model of side effects, persistence, and privacy behavior.

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?

Although the description is long, every clause earns its place: purpose, stable-generation behavior, security property, sharing workflow, and the follow-up call. It is front-loaded with the core verb and resource, and the additional details logically build on that foundation.

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 zero-parameter tool with no annotations and no output schema, this description is nearly complete. It covers what is returned, how the value behaves across calls, the security boundary, and the exact workflow including the next sibling to call. No critical operational detail is left ambiguous.

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 has zero properties, so there are no parameters to document and schema coverage is effectively 100%. The description's only value mention is the returned PSK, not a parameter, so the baseline 4 for a zero-parameter tool is appropriate.

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 opens with a specific action — 'Get this profile's pairing secret (PSK)' — and immediately explains its purpose: granting a human teammate's browser or device access to past conversation history. It also distinguishes itself from the follow-up sibling respond_pairing_requests by describing the secret as the input to that later request-access step.

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 gives a concrete usage scenario: share the secret over a secure channel, have the teammate enter it in the 'request access' prompt, and then call respond_pairing_requests. It clearly identifies when to use the tool, though it does not explicitly list exclusion cases or alternatives beyond naming the related follow-up tool.

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