Aave V3 Ethereum reserves

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

Annotations already cover readOnly/idempotent/destructive, and the description adds real behavioral context: providers are resolved dynamically from the PoolAddressesProvider, and the tool reports nothing if that no longer points at the expected Pool (a silent-empty failure mode). It also discloses the MUTEXA_ETH_RPC configuration requirement, though it does not say which block is used when none is supplied.

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?

Two compact sentences, front-loaded with what is returned, then the resolution/failure semantics, then the credential requirement. Every clause carries information.

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?

No output schema exists, and the description compensates by enumerating the returned fields plus the empty-result condition and the RPC env var. Minor gaps: no mention of the optional symbol filter or how the block is chosen, and no note on result size or per-reserve keying.

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 coverage is 100% and the single optional 'symbols' filter is documented there, so baseline is 3. The description's phrasing 'every ... reserve' does not mention that results can be narrowed by symbol, leaving a small gap between prose and schema.

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 ('Risk parameters of every Aave V3 Ethereum reserve at one block') and enumerates the exact fields returned (max LTV, liquidation threshold, bonus, flags, frozen/paused, oracle price). This is unmistakably distinct from the Hyperliquid/planning siblings.

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 only implied by 'at one block' and 'every reserve' — the agent can infer this is a bulk snapshot read. There is no explicit when-to-use/when-not guidance or naming of an alternative (e.g., a single-reserve lookup or price tool) that would be preferred for other cases.

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