get_market_snapshot

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

No annotations are available, so the description bears the full burden. It states 'real-time' but does not disclose read-only nature, authentication requirements, rate limits, or what constitutes a snapshot. The description is minimal and lacks key behavioral traits.

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 concise sentence with no unnecessary words. However, it is nearly too concise; a slightly longer description could improve clarity without sacrificing conciseness. Still, it is well-structured and front-loaded.

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 and no annotations, the description is insufficient. It does not explain the return format, data frequency, or intended use cases. For a tool with two parameters and moderate complexity, the description lacks completeness.

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?

Schema coverage is 50% with only the 'symbols' parameter having a description. The description adds no extra meaning beyond the schema, failing to explain what symbols are acceptable or what 'workflow_id' represents. It does not compensate for the missing schema descriptions.

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 the verb 'Get' and the resource 'real-time market snapshots' for given financial symbols. It distinguishes from siblings like get_portfolio_snapshot (portfolio-specific) and get_price_history (historical), making the purpose specific and unambiguous.

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 such as get_portfolio_snapshot or get_price_history. The description does not mention any context where this tool is preferred or excluded, leaving the agent to infer usage from the name alone.

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