First observedv0.2.2Sep 2, 2026

TDQS

A3.7/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=false and destructiveHint=false; the description adds meaningful context beyond them by stating the effect is immediate and non-destructive (the account is retained). It does not cover idempotency (what happens if already disabled), permissions required, or reversibility, 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?

A single sentence with the effect front-loaded and zero filler; every clause ('immediately blocking their access', 'without deleting them') carries distinct information.

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

Completeness3/5

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

With an output schema present and annotations covering the safety profile, the description does the core job for a one-parameter mutation. What is missing is operational guidance: how to undo it (marzban_users_activate), error behavior for unknown or already-disabled users, and any permission requirements.

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%, so the schema supplies only the field name plus pattern/length constraints and the description says nothing about username. Since there is exactly one obvious, constrained required parameter, the gap is minor, but the description adds no semantic value beyond the schema.

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?

The description names a specific verb (sets status to disabled) and resource (user), plus the concrete effect (access blocked, account retained). It implicitly distinguishes the operation from deletion, but never names the sibling marzban_users_activate, so the pairing is left for the agent to infer.

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 only implied: 'without deleting them' suggests the tool is for suspending rather than removing an account. There is no explicit when-to-use statement, no prerequisite, and no pointer to marzban_users_activate as the reversal path, so the agent must derive the choice from sibling names.

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