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

Beyond the read-only and idempotent annotations, the description adds important context: exchange API credentials are excluded, configured fee percentages can be misleading under auto mode, and effective fee fields plus fee_source explain the actual applied rate. It also discloses the nuanced manual_fixed behavior and that unknown percentages are omitted rather than reported as zero.

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 credential exclusion are front-loaded, but the description then spends most of its length on dense fee-field semantics that may duplicate output-schema documentation. The information is useful, but the result is longer and less scannable than ideal for a single-parameter read tool.

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 read-only configuration getter with a fully described one-parameter schema and an output schema, the description covers the essential purpose, security caveat, and the most easily misinterpreted fee fields. It does not mention sibling routing or error behavior, but the core invocation context is complete.

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 runtime_id parameter is already documented with its pattern and source in spotgrid.list_runtimes. The description does not add any runtime_id-specific semantics beyond the schema, so the baseline score of 3 is appropriate.

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 uses a specific verb and resource: it 'Reads one runtime's trading configuration' and enumerates the configuration areas returned. This clearly distinguishes it from status, order, or history siblings, though it does not explicitly name an alternative tool.

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?

There is no explicit guidance on when to call this tool versus siblings such as spotgrid.get_status or spotgrid.get_usage. Usage is only implied by the phrase 'trading configuration', with no alternatives or exclusions stated.

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