search_malaysian_news

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

The description says it 'Fetches Malaysian news and filters by keyword', which discloses the core behavior. However, since no annotations are provided, the description carries the full burden and does not mention output behavior, freshness, source restrictions, or potential no-result cases.

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, front-loaded with the main purpose, and uses a short Args block to reinforce parameter semantics. Every sentence contributes useful 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?

Given only two parameters, one required, and an output schema present, the description covers the essentials well. It gives query examples and sources format, though an explicit note about when to prefer get_malaysian_news would make it fully complete.

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%, and the description compensates by explaining 'query' as search keywords with examples and 'sources' as comma-separated sources. It adds meaning beyond the bare schema titles, though it does not enumerate all possible source values.

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?

States a specific verb ('Search') and resource ('Malaysian news') with an explicit scope qualifier ('specific topics'). The 'Use when the user asks about specific Malaysian topics' framing distinguishes it clearly from the sibling 'get_malaysian_news', which implies the broader non-search fetch.

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?

Provides clear conditions for use with concrete examples ('Anwar news', 'ringgit', 'Johor'). It does not explicitly name alternatives or state when not to use this tool, so it lacks exclusions but still gives a usable trigger context.

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