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. It only states that the output is machine-readable, but does not describe the actual contents, format, safety profile, or potential side effects. For a read operation, it doesn't even confirm it is non-destructive or what data it accesses beyond 'signals'.

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, focused sentence: 'Today's machine-readable signal digest (the CoinBucha Daily Brew).' It is concise, front-loaded, and contains no filler. Every word contributes to explaining the tool's purpose, making it appropriately sized for a zero-parameter tool.

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?

The tool is simple (no params), but with no output schema and no annotations, the description should explain what the digest contains and how it relates to sibling tools. It merely labels the output without detailing the signals covered, the format, or how it differs from scanning signals. This is insufficient for an agent to fully understand the tool's return value.

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 input schema has zero parameters, so the baseline is 4. The description correctly adds nothing about parameters since there are none. The schema coverage is 100% (vacuously), so the description does not need to compensate for missing parameter documentation.

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 it provides 'Today's machine-readable signal digest', indicating a verb+resource: retrieving a digest. It differentiates from sibling tools like get_etf_flows or get_network_signal, which focus on specific signals, though it does not explicitly name them. The word 'digest' implies a compilation, which adds some specificity.

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 provided on when to use this tool versus alternatives. The description mentions 'Today's' implying daily use, but there is no explicit statement about when to prefer this over scan_signals or other specific signal tools. It lacks any exclusions or alternative references.

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