get_market_snapshot

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

Annotations already provide safety profile (readOnly, idempotent, non-destructive). The description adds value by clarifying it's a daily snapshot that combines all data collectors, which informs the agent about data freshness and scope. No contradictions.

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?

3 sentences, front-loaded with purpose. The Vietnamese translation is slightly redundant but does not harm conciseness. Every sentence contributes information.

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 no output schema, the description sufficiently explains the tool's output by listing the 13 data collectors. It mentions 'daily snapshot' for timing context. Could be improved by hinting at return format, but overall complete for a zero-parameter tool with good annotations.

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 0 parameters with 100% coverage, so baseline is 4. The description adds context about what data is included (the 13 collectors), which helps the agent understand the output without needing parameter details.

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 'Complete daily market intelligence snapshot' and lists all 13 data collectors, distinguishing it from sibling tools that focus on individual aspects like get_macro_snapshot or get_sector_rotation.

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?

The description implies usage for a broad overview ('single call for comprehensive overview') but does not provide explicit guidance on when to use this vs. individual collectors or alternative snapshots. No exclusions or alternatives are mentioned.

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