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

With no annotations provided, the description carries the full burden and does disclose meaningful non-schema behavior: cost ($0.0200 USDC per call), the POST endpoint, and that payment/execution uses x402 with 'data/langsung'. The main gap is that it doesn't describe the output shape or failure behavior, but pricing and payment context are genuinely valuable.

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?

Front-loads the action, then inputs, then pricing/execution using a clean '||' separator. Every clause carries information, though the Malay/English mix and the endpoint URL add some density without waste.

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 no-output-schema, no-annotation combined tool, the description covers what it does, its inputs, cost, and execution method. It stops short of explaining the returned summary/Markdown structure, but overall an agent has enough to invoke it correctly.

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 100%, so the schema already documents url, arahan, and had. The description restates the same three inputs with matching glosses ('apa yang hendak difokuskan', 'bilangan aksara') and adds no format, range, or default detail beyond what the schema provides, so the 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?

States a specific compound operation: fetch a URL, convert to clean Markdown, and summarize with AI 'dalam SATU panggilan' (in one call). This distinguishes it conceptually from the sibling pair kikis-web and ringkas by emphasizing the combined single call, though it never names those siblings directly as alternatives.

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 phrase 'dalam SATU panggilan' implies the tool exists to avoid chaining kikis-web + ringkas, but there is no explicit when-to-use or when-not-to-use guidance and no conditions under which a separate scrape or summarize call is preferable.

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