asc_add_subscription_group_localization

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

No annotations are provided, so the description carries the full behavioral burden. It does disclose one useful fact — that this localization is needed to resolve a MISSING_METADATA condition — but says nothing about permissions, idempotency, what happens to existing localizations, or approval_id 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?

It is short, but brevity here comes from under-specification rather than efficiency — a single parenthetical fragment that is not even a complete sentence. There is no front-loaded statement of the tool's action or scope.

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 4-parameter mutation tool with no annotations and 0% schema description coverage, the description is far too thin. An output schema exists so return values need not be explained, but the inputs, side effects, and usage context are all absent.

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?

Schema description coverage is 0%, and all four parameters (group_id, locale, approval_id, name) are undocumented in the schema. The description adds only a partial hint about 'name' (its role in MISSING_METADATA) and leaves group_id, locale, and approval_id entirely unexplained, failing to compensate for the coverage gap.

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 reads as a parameter label ('Subscription group display name') rather than a statement of what the tool does. It never uses a verb like 'adds' or 'creates', so the agent must infer the action from the tool name alone. It only incidentally distinguishes it from siblings like asc_localize_group.

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 parenthetical 'required for MISSING_METADATA' hints at one triggering condition, but there is no when-to-use guidance, no mention of alternatives (e.g., asc_localize_group vs. this tool), and no prerequisites. The agent gets a fragment of context, not routing guidance.

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