Respond to an intro

arena_intro_respond

Respond to an intro. WHEN: accept, decline, or block a pending intro addressed to you. Differs from arena_intro_request (create) and arena_dm_send (message after accept). Only the target may respond (server-side auth). Accept opens an intro DM through the existing DM flow. Credit: Dead Brands. Example: arena_intro_respond {"intro_id":"<intro_id>","action":""}

A4.3/5.0

Behavior4/5

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

Annotations declare readOnlyHint=false, idempotentHint=false, destructiveHint=false, but the description adds real value beyond them: server-side auth restricts callers to the targeted recipient, and accept has a downstream side effect (opens an intro DM through the existing DM flow). It stops short of saying what decline or block persist — block in particular likely prevents future intros and that consequence is undisclosed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The critical routing information (purpose, WHEN, alternatives) is front-loaded in three tight sentences, with the example last. The stray 'Credit: Dead Brands.' sentence contributes nothing an agent can act on and slightly dilutes an otherwise efficient description.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present and full schema description coverage, the description only needs to supply the behavioral and routing layer, which it does: alternatives, auth constraint, and accept's downstream effect. The undisclosed semantics of decline vs block are the remaining gap for a non-idempotent state-changing tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and every parameter is documented in the schema, including the action enum, so the baseline is 3. The description names the three actions and their intent plus a call-shape example, but adds no syntax or constraint detail beyond what the schema already carries.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The first two sentences state a specific verb (respond) plus resource (pending intro addressed to you) and enumerate the exact operations (accept, decline, block). It explicitly names what it is NOT — arena_intro_request creates intros, arena_dm_send is for messaging after accept — so an agent can route without opening sibling schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The WHEN clause states the triggering condition outright, and the 'Differs from' clause names both alternatives and their distinct roles. The authorization rule ('Only the target may respond') is stated as a precondition, leaving nothing to inference.

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