get_inventory_ledger

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It describes the output content but does not mention read-only nature, result size limits, pagination, or latency expectations, which would help an agent anticipate behavior.

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 sentences, front-loaded with the action (Get inventory ledger summary) and elaborated with specific movements. Each phrase adds value, though the second sentence is slightly redundant.

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 tool with no output schema and 100% parameter coverage, the description adequately explains what the ledger contains. However, it lacks information about time range granularity, data recency, or how this differs from other inventory tools among the many siblings.

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% with clear parameter descriptions for startDate and endDate. The description adds no additional meaning beyond the schema, so it meets the baseline without extra value.

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 clearly states the tool retrieves an inventory ledger summary showing specific movement types (receipts, shipments, returns, adjustments, balance changes) and states its purpose to track inventory movements, distinguishing it from simpler summary tools like get_inventory_summary.

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?

The hint 'helps track where inventory went' implies a traceability use case but does not explicitly state when to use this tool over alternatives like get_inventory_summary or get_fba_inventory_details, nor does it provide exclusion criteria.

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