list_habit_sections

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

No annotations are provided, so the description technically carries the full burden, but this is a zero-parameter read with no destructive potential, so the disclosure bar is low. The description does not state that it is read-only or describe ordering/pagination, leaving a modest gap.

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?

A single short sentence with the key noun front-loaded after the verb — nothing wasted. It is arguably too terse to be maximally useful, but it is structurally clean.

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 simple enumeration tool this is minimally complete, but with no output schema and no annotations, the description never says what a 'section' contains or in what form results return, leaving an agent to guess at the shape of the response.

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 tool takes zero parameters, so there is nothing for the description to disambiguate; the baseline for a parameterless tool is 4. No parameter meaning is missing.

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+resource ('Lists habit sections') and clarifies the domain term with the parenthetical '(groups)'. It implicitly separates from the sibling list_habits (individual habits vs. their grouping container), but never names that distinction explicitly, so it falls short of a 5.

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?

Usage is only implied by the verb 'Lists' — an agent can infer this is a read-only enumeration call with no arguments. There is no statement of when to prefer this over list_habits or query_habit_checkins, and no prerequisites or exclusions are given.

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