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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so the safety profile is covered. The description adds useful non-annotation context: the membership-based scoping and the exact fields returned. It omits whether results are paginated, ordered, or capped, which is the remaining behavioral 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?

Two sentences, no filler, with the scope and returned fields front-loaded and the id-linkage note placed where it is immediately actionable. Every clause earns its place.

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?

There is no output schema, so the description must convey the shape of the return value, and it does by naming id, name, repository, and role. For an otherwise simple zero-parameter read, that leaves only minor gaps such as pagination or ordering behavior.

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 are no parameter semantics for the description to supply; the baseline for a 0-param tool is 4. The description correctly implies no input is needed by describing only the account-scoped result set.

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?

Uses a specific verb+resource with explicit scope ('every Joxo project this account is a member of') and enumerates what each entry contains (id, name, repository, role). This is plainly distinguishable from sibling get_project (single project) and list_tasks.

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 second sentence gives real usage direction: the returned ids are the project_id the other Joxo tools accept, effectively telling the agent to call this first to discover ids. It stops short of naming an alternative or stating when not to use it, so it is clear context without explicit exclusions.

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