analyze_sma_snapshot

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

With no annotations, the description carries the full burden. It discloses that only latest values are provided, not historical data. However, it lacks details on side effects, permissions, performance, or output structure, making it adequate but not thorough.

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 concise, with only two sentences plus a warning. It front-loads key terms (SMA, golden cross, dead cross) and is mostly efficient. However, the Japanese text might reduce clarity for non-Japanese readers, and a structured format could improve scannability.

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 tool has 4 parameters with no schema descriptions, no annotations, and no output schema, the description is incomplete. It fails to explain the output format, the role of limit and periods, and the exact meaning of alignment state. A more detailed description is needed for reliable use.

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 0%, and the description provides no explanation of the four parameters (pair, type, limit, periods). It only vaguely relates to 'latest values' but does not define what each parameter does or how they affect the snapshot.

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 identifies this tool as an SMA snapshot tool providing latest values, cross detection, and alignment state. It distinguishes from prepare_chart_data but does not explicitly differentiate from other snapshot siblings like analyze_ema_snapshot or analyze_mtf_sma.

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 explicitly states when not to use this tool (for chart drawing, use prepare_chart_data). However, it does not provide guidance on when to use this over other snapshot tools, leaving some ambiguity.

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