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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds no behavioral context of its own — no indication of what readiness checks are evaluated, whether results are cached, or whether the response is scoped to a workspace/company — so it earns nothing beyond the annotations.

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 description is two identical sentences plus an operation ID and a pointer sentence, so half the text is pure duplication. It is short but not front-loaded with any meaningful information about the resource or its outcome.

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?

With an opaque untyped query object, no output schema, and no explanation of return contents, an agent cannot predict what it will receive or how to shape the query. For a readiness-check endpoint whose value is entirely in its response shape, this leaves a critical gap.

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% and the two parameters (a free-form nested 'query' object with additionalProperties and an empty 'params' object) are completely undescribed. The single useful signal is the pointer to describe_operation for native request schemas, which partially compensates but leaves the actual query keys and their formats unexplained.

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 only restates the HTTP method and path ('GET /api/accounting/setup/readiness') twice, which adds nothing beyond the tool name and title. It never says what 'setup readiness' means, what entity the readiness applies to, or what the caller would learn from it, and it does nothing to distinguish it from siblings such as get_journal_entries_readiness or get_accounting_compliance_settings.

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 statement of when to use this endpoint versus alternatives in the large accounting sibling set (e.g., get_accounting_compliance_settings, get_journal_entries_readiness). The only navigational hint is that describe_operation provides native request schemas, which addresses parameters, not tool selection.

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