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

With no annotations, the description carries the burden and does meaningful work: it discloses the verification checks performed (target, selector, token/market binding, sender, nonce, zero value), that the decision is short-lived EIP-712 and only issued when Insight signing is configured, and that it never authorizes, signs, or broadcasts. It omits what happens on a failed verification (error vs negative decision) and any rate/latency characteristics.

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?

Three dense sentences with the purpose front-loaded, the verification behavior next, and the safety hand-off last. No filler, though jargon ('Insight risk evidence', 'PriorSeal', 'ALLOW') is used without definition, which costs a bit of immediate comprehensibility.

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 complex two-object nested schema with no annotations and no output schema, the description covers the essentials an agent needs: what it verifies, that it produces a short-lived signing decision rather than a transaction, and what must happen afterward. Gaps remain around the shape of the returned EIP-712 decision and failure modes.

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%, so the description must supply meaning, and it does map the transaction fields implicitly (target=to, selector=data, sender=from, nonce, value must be zero) plus token/market binding from the guard object. However, it says nothing about collateralValueUsd/debtValueUsd, the optional marketId, the protocolId enum values, or the fixed chainId 143, leaving several leaf fields undocumented anywhere.

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 gives a specific verb and artifact ('Create portable Insight risk evidence') and narrows scope to one exact unsigned direct Aave V3 Monad or Morpho Blue Monad supply/borrow call, which implicitly separates it from the broader monad_lending_guard and the base/other-chain variants. It never names those siblings explicitly, so the differentiation relies on the reader inferring 'exact' vs non-exact.

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?

It carves out a clear usage envelope: a single, exact, unsigned, direct call on two named protocols, which excludes batched/router calls by implication. It also states the downstream step ('bind an ALLOW through PriorSeal or another user-authorization system'), but gives no explicit when-to-use-this-vs-monad_lending_guard guidance.

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