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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true. Description adds behavioral context by specifying computed metrics (ROE, ROA, etc.) and that it supports multiple analysis strategies. No contradiction with annotations. Description enriches transparency beyond annotations.

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 concise: two English sentences and one Vietnamese translation. Front-loaded with main function. Each sentence adds value. Could be slightly more compact by combining, but no 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?

Covers main outputs and strategies, but lacks explanation of how strategies are invoked (parameter only has symbol); no mention of return format or that it may return all strategies. With no output schema, more detail on results would be helpful. 'BCTC' may be ambiguous without full name in English.

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 100% with parameter 'symbol' described as 'Stock ticker, e.g. FPT, VNM, VCB'. Description adds context that it is for Vietnamese stocks, but does not provide additional parameter details beyond schema. Baseline 3 justified.

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?

Description clearly states it retrieves financial statement analysis for a Vietnamese stock, listing specific metrics (ROE, ROA, debt ratios, Altman Z-score) and strategies (Buffett, Graham, Lynch, O'Neil, Piotroski). Distinct from siblings like 'get_financials' which likely returns raw data, and 'get_stock_info' which is general info. Verb 'Get' and resource 'BCTC analysis' are specific.

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 explicit guidance on when to use this tool versus siblings such as 'get_financials', 'get_technical_signals', or 'screen_stocks'. Does not state prerequisites, context, or exclusions. An agent cannot determine from description alone when this is the appropriate choice.

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