First observedv0.2.2Sep 2, 2026

TDQS

B3.2/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the safety profile is covered. The description adds that the effect is a status-field change rather than a destructive write, but says nothing about idempotency, behavior on an already-active or nonexistent user, or any side effects on expiry/subscription state.

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?

A single front-loaded sentence with zero filler. Brevity is appropriate for a one-parameter status toggle, though the sentence stops short of the point where it would be genuinely useful.

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 and annotations cover the safety profile, so the remaining burden is small for a single-parameter toggle. The main gap is failure/edge-case behavior (unknown user, already active), which is a moderate rather than critical omission.

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?

Only one parameter with 0% schema description coverage, so the description should carry weight; 'a user's status' at least implies the username identifies the target. The format constraints (pattern, 3-32 chars) live in the schema itself, so nothing further is expected here, but no meaning is added beyond the field name.

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+resource ('sets a user's status to active'), and the mention of 'status' clarifies the mechanism beyond the title alone. It does not, however, differentiate itself from the sibling marzban_users_deactivate or explain what 'active' implies for the user's subscription.

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

Usage Guidelines2/5

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

No guidance on when to use this versus marzban_users_deactivate, marzban_users_update, or marzban_users_hold, and no stated preconditions. The agent must infer entirely from the tool name that this is the inverse of deactivate.

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