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

No annotations provided, so description bears full burden. It names the indicators used but does not disclose output format, data freshness, failure modes, or if signals are real-time. This is adequate but not thorough for a synthetic indicator 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?

Single sentence, directly to the point, contains all necessary functional information without redundancy.

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?

For a tool generating trading signals with no output schema, the description covers the core logic but lacks specifics on output shape (e.g., buy/sell/hold, signal strength). Adequate but leaves room for improved 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?

The schema already describes both parameters (symbol and days) with 100% coverage. The description adds no extra semantic value beyond the schema, so baseline 3 applies.

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 generates stock trading signals based on technical indicators (MACD, KDJ, RSI, Bollinger Bands). It specifies the verb 'generate' and the resource 'trading signals', and it distinguishes from sibling tools by focusing on multi-indicator synthesis.

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 use for judging buy/sell timing via technical analysis. It provides clear context but omits explicit exclusions or alternatives when other stock analysis tools (e.g., stock_indicators) might be more appropriate.

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