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

With no annotations, the description carries the full burden, and it does well: it discloses the exact return contents (affected-model matrix, fixed firmware versions, loss figures, open questions) and flags that the record is volatile and updated as sources move. It never explicitly confirms read-only behavior or authorization needs, but this is clearly a read of public incident data.

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?

Front-loads the core identity in the first clause, then layers in return contents and usage scope in an order an agent can scan. Four sentences is a touch long, and the 'live/developing story' framing is stated twice, but nothing is truly wasted.

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 output schema, the description steps in and enumerates what is returned, and with no annotations it still conveys the operational character (live, evolving record). An agent has everything needed to call a zero-arg status tool 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 parameter-semantics baseline of 4 applies. There is nothing for the description to clarify here.

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 (get) and a precisely named resource (Coldcard entropy failure incident status), then spells out the underlying defect and its consequence. No sibling tool covers this incident, and the topic specificity makes it trivially distinguishable from get_hardware_wallet_scores or list_custody_incidents.

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?

Gives clear when-to-use context: 'any question about Coldcard safety, whether a device or seed is affected, what to do about it, or whether self-custody is still safe.' It stops short of naming alternatives or exclusions, so a 4 rather than 5.

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