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

No annotations are provided, so the description carries the full behavioral burden, yet it discloses nothing about side effects, whether the write is idempotent, what an 'actuals minute' mutation affects, or whether it requires prior attestation/settlement steps. The word 'Report' vaguely implies a write, but nothing concrete is stated.

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?

A single short phrase is appropriately sized for a zero-parameter tool and is front-loaded, but it is under-specified rather than genuinely concise — it earns its brevity by simply saying very little.

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 no annotations, no output schema, and no parameter documentation, the description is the only source of meaning, and a four-word phrase leaves an agent unable to tell what the tool does operationally or when to invoke it among seven 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?

The schema declares zero parameters, so per the rubric this is a baseline 4; there is no parameter semantics for the description to clarify or omit.

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 largely restates the name: 'add_actuals' becomes 'Report one actuals minute'. It does add the cardinality ('one') and swaps the verb to 'report', but the domain term 'actuals minute' is never explained, and it is indistinguishable from siblings like add_history, open_event, or register_manifest.

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 this tool applies versus add_history, open_event, settle, or the other siblings, and no prerequisites or exclusions are given. An agent has only the tool name to infer context, which is not enough in a domain-specific toolset.

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