inv_add_forecasting

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

With no annotations provided, the description carries the full burden of behavioral disclosure, yet it only reveals the action ('Generate') and a licensing trait ('Pro feature'). It does not mention side effects, file writes, prerequisites, or whether an existing inventory system must be present.

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 a single front-loaded sentence with no wasted words, and the 'Pro feature' parenthetical adds a meaningful constraint. It is efficient, though the brevity reflects thin content rather than a rich, well-structured explanation.

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 only 2 parameters and no output schema, critical facts remain unknown: what artifact is generated, where it is written, and whether the project must already have an inventory system. An agent cannot reliably predict the result or the required project state.

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 50%: 'directory' is documented as 'Project directory', but 'api_key' has no schema description. The description adds no parameter meaning at all, leaving the api_key's purpose and the directory semantics unclarified beyond the schema.

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 verb ('Generate') and a resource ('inventory forecasting'), which sets it apart from the inventory family (inv_generate_system, inv_add_alerts) through the forecasting object. However, it does not clarify what 'forecasting' generation produces (code, config, or a report), so the purpose could be sharper.

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?

No guidance is given on when to use this tool versus alternatives like inv_generate_system or inv_add_alerts. The parenthetical 'Pro feature' is a licensing constraint, not usage direction, so an agent must guess the prerequisite context.

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