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

Annotations already declare the safe read-only, idempotent profile, but the description adds real behavioral context beyond them: a hard limit of 50, newest-first ordering, the status lifecycle (WAITING/PROCESS/DONE/FAILED), and what fields appear in each state. It does not discuss auth requirements or what happens when no records exist, so it falls short of 5.

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?

A single front-loaded paragraph with no filler; the parenthetical status values and return-field list are dense but each element is useful. It could be split into purpose, filtering, and return-shape clauses for easier scanning, but nothing is wasted.

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 simple read-only list tool with no output schema, the description covers the important ground: ordering, limit, status values, and the meaningful return fields per state. Remaining gaps (auth, empty-result behavior, id/uuid requirement) are minor for this complexity level.

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?

With 0% schema description coverage, the description carries the parameter burden and does it well: it explains storages_account_id vs storages_account_uuid as alternatives and supplies the status values that the schema lacks as an enum. It leaves gaps, though: it doesn't say whether one of id/uuid is required (the schema marks all params optional), what null status defaults to, or whether both can be passed.

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?

States a specific verb and resource ('The latest 50 remote file adds of a storage account') with clear scope: newest first, plus the fields returned. It is distinct from list_storage_files in wording but never names or contrasts a sibling explicitly, so it stops short of a 5.

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?

Usage is implied: inspect recent remote-file additions for an account, optionally filtered by status. There is no explicit when-to-use guidance, no mention of alternatives like list_storage_files or list_storages_accounts, and no when-not conditions.

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