schwab_stream_quotes

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

No annotations provided, so description must fully disclose behavior. It ambiguously mixes 'snapshots' and 'streaming' without clarifying if it's one-time or continuous, nor does it mention permissions, rate limits, or connection management.

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?

Description is extremely concise with one sentence and an Args line, front-loaded with purpose. No wasted words.

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 the streaming nature and existence of output schema, the description is too sparse. It omits details on stream lifecycle, data format hints, and prerequisites, leaving many open questions.

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 description coverage is 0%, but the description adds 'List of equity ticker symbols' for the symbols parameter, providing basic meaning beyond the raw schema. However, it lacks constraints like case sensitivity or maximum count.

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 tool gets 'real-time equity quote snapshots' from 'Schwab streaming,' specifying the resource and action. It distinguishes from sibling tools like schwab_stream_option_quotes and schwab_quotes.

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 on when to use this tool versus alternatives like schwab_quotes, schwab_stream_level2, or schwab_stream_option_quotes. Missing when-not-to-use or context for selection.

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