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

With no annotations, the description carries the full burden and does disclose two useful traits: the return is a checklist and the call is 'low-cost' so it is safe to invoke frequently. It does not address side effects or permissions, but a no-param workflow helper is unlikely to have any.

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?

Three short sentences, front-loaded with the trigger condition before the explanation. The second and third lines are slightly redundant in restating the 'reminder' idea, but overall it is tight.

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 simple zero-param helper with no output schema, the description covers what it does, when to call it, and its cost profile. An agent has everything it needs to invoke it correctly.

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 tool takes zero parameters, so the schema carries no semantic load and there is nothing for the description to clarify. Baseline for a 0-parameter tool is 4.

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 names the resource and result clearly: it 'returns a step-by-step checklist' for the Awareness memory workflow. It distinguishes itself from the operational siblings by being the meta/guidance tool rather than a memory operation, though it does not name any sibling directly.

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?

It gives an explicit trigger condition ('when you're unsure what to do next') and reinforces it ('use it anytime you need a reminder of the workflow'). No exclusions are stated, but for a zero-cost meta-helper there is little to exclude.

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