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

Annotations already cover read-only, idempotent, non-destructive, open-world, so the description correctly spends its budget elsewhere: freshness ('recomputed this moment'), the full enumerated result vocabulary, the fact that it ends with a prescribed next call, and that it is keyless with nothing to sign. That is real value-add, with only return-shape detail duplicating the output schema.

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 purpose and state enumeration are front-loaded, but the text is a single run-on sentence and 'Free and keyless' is stated twice ('Free and keyless' then 'Cost and signer: free and keyless, nothing to sign'). Several clauses, especially 'the condition's rung ... read from the Standing', add jargon without 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?

An output schema exists, so return values need not be spelled out, yet the description usefully previews the state vocabulary an agent will parse and flags that it emits a prescribed next call. What remains missing is failure behaviour (invalid/unknown bid id) and how fresh 'this moment' guarantees are, but this is close to complete for a one-parameter read.

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?

One parameter at 100% schema coverage, and the schema already states it is the OBID_ id from submit_outcome_bid. The description adds no format constraints, validation rules, or error behaviour for an unknown or settled id, so 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?

Names a specific verb (read/recompute) and resource (an outcome bid's status), and enumerates the state space it reports, so an agent knows exactly what comes back. It is distinguishable from submit_outcome_bid and prepare_outcome_bid by the id-based read framing, though the idiosyncratic vocabulary ('rung at the place', 'the Standing') is never grounded.

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 schema note that the id comes 'from submit_outcome_bid' suggests reading after submission, and 'Ends with the literal next call' hints this is a polling/decision step. No explicit when-to-use or when-not, and no routing against near-neighbours like place_status, net_order_status, work_status, or request_status.

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