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

Far beyond what the annotations provide. It discloses engine-scoped approvals that drop out per settlement venue, that settlement-committed collaterals emit no approval (fills go on the commit ledger), that human identity is never chain-local periphery, and that addresses are UUPS/permanent. This is unusually rich operational context.

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 core purpose is front-loaded in the opening clause, but the remainder is a dense run-on covering approvals, settlement semantics, creator roles, and identity services. Much of it is useful, yet the lack of sentence breaks and mixed scope makes it harder to parse than it needs to be.

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?

An output schema exists, so return values need no explanation, and the description covers the behavioral complexity (approvals, settlement, permanence) thoroughly. It is complete for invocation, though the sprawl of tangential notes (identity service, cancel claims) dilutes rather than sharpens the essential guidance.

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 100% for both optional filters (chainId, collateral), so the schema already documents them fully. The description's 'per-chain' and 'per collateral' phrasing aligns with the filters but adds no format or syntax detail beyond the schema. Baseline 3 applies.

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 states a specific resource set: per-chain collateral addresses (MarketRouter proxies, OutcomeToken1155, factories) plus the one-time trading approvals. An agent can tell this apart from list_collateral or get_factory_config by content, though it never names those siblings to explicitly disambiguate.

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 gives concrete usage conditions: creator agents must pick a collateral with creation=true, cancellations and direct claims need no approval, and agents should verify against /trade/prepare or /trade/simulate rather than assuming permanence. It stops short of explicitly routing between this tool and sibling discovery endpoints.

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