hedera_get_account_allowances

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

No annotations are provided, so the description carries the full burden. It mentions 'Read' suggesting no side effects, but does not disclose rate limits, cost, or what 'active' means. Minimal behavioral context beyond the verb.

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?

The description is a single sentence of 11 words, efficiently conveying the core purpose. It is front-loaded but slightly overly terse, missing some context.

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?

Given no output schema and no annotations, the description lacks details on return values, pagination, error handling, and the definition of 'active'. It does not fully cover the needed context for a simple read tool.

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?

The schema has 0% description coverage for the single parameter 'accountId'. The description does not explain the expected format (e.g., shard.realm.num or alias) beyond the type string. No additional meaning is added.

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 clearly states the action ('Read'), the resource ('account's active HBAR allowances'), and the source ('Mirror Node'). It distinguishes itself from sibling tools like 'hedera_get_account_token_allowances' by specifying 'HBAR (crypto)' allowances.

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 description implies usage for reading HBAR allowances but does not explicitly state when to use this tool versus siblings like 'hedera_get_account_token_allowances' or 'hedera_get_account_nft_allowances'. No guidance on prerequisites or context is provided.

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