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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive), but the description adds real value beyond them: 'recomputed this moment' signals live/uncached freshness, 'Free and keyless' discloses cost and no-auth, and 'Ends with the literal next call' discloses a return-behavior trait. It does not mention rate limits or failure modes.

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?

Purpose is front-loaded, which is good, but the body is a single dense run-on sentence that stacks state vocabularies ('rung lapsed', 'rung reached', 'read from the Standing') with heavy domain jargon, making 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 not be re-explained, and annotations cover the safety profile. The description is complete enough for an agent to call a single-param read tool correctly, with only usage routing left unaddressed.

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% and the single outcomeBidId parameter is fully documented in the schema itself ('The OBID_ id from submit_outcome_bid'). The description adds no format or syntax detail beyond the schema, so the 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?

States a specific resource (an outcome bid) and operation (read its current standing), and enumerates the possible states it reports. An agent can tell this reads bid status, though it never explicitly contrasts itself with the write counterpart submit_outcome_bid or the broader place_status/work_status 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: the enumerated states and the phrase 'Ends with the literal next call' suggest it is a checkpoint call during an outcome-bid flow. There is no explicit when-to-use/when-not or routing to alternatives such as next_action or the submit/prepare siblings.

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