egx_fibonacci_retracement

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

No annotations are present, so the description must carry full behavioral disclosure. It only says 'analysis' without indicating whether it is read-only, what output to expect, or any side effects. This is insufficient for understanding the tool's behavior.

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 short and front-loads the core purpose. However, the 'Args:' section is somewhat mechanical and could be integrated more naturally. Overall, it is efficient with 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?

The description adequately explains the three input parameters but does not describe the output or the nature of the retracement analysis (e.g., levels, percentages). Given no output schema, more detail on return values would improve 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 input schema provides 0% description coverage. The description compensates by listing allowed values and defaults for 'lookback' and 'timeframe' (e.g., '1M', '3M', '52W', 'ALL' and '5m', '15m', '1h', etc.). The 'symbol' parameter is described simply as 'EGX stock symbol,' which is basic but adds some context.

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 it performs 'Fibonacci retracement analysis for EGX stocks,' specifying the analysis type and market. It distinguishes well from sibling tools, none of which duplicate this function.

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 the tool is for technical analysis of EGX stocks but provides no explicit guidance on when to use it versus other analysis tools or alternatives. No exclusions or prerequisites are mentioned.

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