list_sections

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

No annotations are provided, so the description carries the behavioral burden. Saying 'List all' usefully implies a complete, non-paginated enumeration with no filtering, but it says nothing about whether this requires any setup, how large the result may be, or how lang affects the returned titles.

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-loaded single sentence naming the resource and return fields, followed by a compact parameter note. The trailing fragment 'lang: 'en' or 'pt'.' is clipped but efficient; nothing is wasted.

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?

An output schema exists, so return shape need not be explained, and the tool is a simple zero-required-parameter read. The main completeness gap is routing: with nine siblings including get_section and search_kb, the description should say when this enumeration is the right call.

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% for the single 'lang' parameter – the schema only supplies a default of 'en' and no description or enum. The description compensates by enumerating the accepted values ('en' or 'pt'), which is the key missing information, though it never states what lang actually changes or that it defaults to 'en'.

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 and resource ('List all numbered sections of the knowledge base') and even names the returned fields (id, title, level), so the agent knows exactly what it gets. It does not distinguish itself from siblings like get_section or search_kb, leaving the choice to inference.

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 when-to-use or when-not-to-use guidance and no reference to the obvious alternatives (get_section for a single section, search_kb for targeted lookup). The agent must infer that this is the enumerate-everything option from the word 'all'.

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