list_accounts

Read-only

Returns all social accounts owned by the API key profile, including disconnected accounts. Partner accounts also receive external_user_id on each account and can filter by it.

A3.8/5.0

Behavior4/5

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

Annotations already cover the safety profile (readOnly, non-destructive, closed-world), and the description adds real value on top: that disconnected accounts appear in results and that partner accounts carry an extra external_user_id field. It does not mention pagination or result ordering, which keeps it below a 5.

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

Conciseness5/5

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

Two tight sentences, zero filler, with the primary scope statement front-loaded and the partner-specific caveat deferred to second position. Every clause carries information.

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?

An output schema exists so return values need no explanation, and the description correctly focuses on scope and the partner-only field. The only real gap is filter behavior for non-partner profiles, a minor omission for a one-optional-parameter read 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 description coverage is 0% for the single external_user_id parameter, so the description must compensate. It does explain that the value can be used to filter results, but leaves open what happens for non-partner profiles (error vs. ignored) and what identifier format is expected.

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

Purpose4/5

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

Specific verb and resource ('Returns all social accounts owned by the API key profile') with an explicit scope note that disconnected accounts are included. That scope phrase implicitly separates it from the sibling list_active_accounts, though the sibling is never named.

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

Usage Guidelines3/5

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

Usage is implied rather than stated: 'including disconnected accounts' tells the agent this is the complete-list variant versus list_active_accounts, but there is no explicit when-to-use/when-not-to-use sentence or named alternative, so the agent must infer the routing.

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