get_market_brief

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

No annotations are present, so description carries full burden. It honestly describes the brief's content (macro regime, crypto signals, etc.) with no hidden side effects. However, it does not disclose potential costs or rate limits, which would be helpful for a synthesizing tool.

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?

Two sentences, front-loaded with main purpose then details. No filler or redundancy; every word adds value.

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?

Given tool complexity (27 signals, multiple data types), description covers all major components concisely. Output schema exists to detail return structure, so description's job is complete.

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?

Input schema has zero parameters with 100% description coverage, so baseline is 4. Description effectively conveys what the tool returns, which is the only relevant semantics for a parameterless tool.

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?

Description clearly states the tool's purpose: get a full AI market brief synthesizing all 27 live signals. It lists specific components (macro regime, crypto signals, Fear & Greed, Polymarket edges) which distinguishes it from siblings like get_market_sentiment or get_signal.

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?

Implies usage for comprehensive market overview due to wording 'full AI market brief', but does not explicitly state when to use versus alternatives like get_market_sentiment. No exclusion or alternative guidance provided.

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