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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint, so safety is covered. With no output schema, the description carries the return-shape burden and does so richly (per-org fields, empty projects arrays, projectsWithoutOrganisation). It stops short of auth/permission or pagination notes, but the behavioral disclosure is well above the annotation baseline.

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 with the core result shape, then each clause adds routing or disambiguation value rather than filler. It is a dense, somewhat long run-on, but virtually every sentence earns its place, so only minor tightening is possible.

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?

With no output schema, the description fully covers return values (both org and project fields, empty arrays, projectsWithoutOrganisation) and how to consume the resulting IDs. For a single-parameter listing tool with safety annotations in place, nothing an agent needs is missing.

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 100%, so the baseline is 3. The description goes beyond the schema's terse 'Only list this organisation and its projects' by explaining the parameter's purpose: narrowing to one organisation and disambiguating same-named projects. That added rationale is genuine value over the structured field.

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' your workspace's organisations and their projects) and enumerates exactly what fields come back. It differentiates itself from siblings by naming traceable_workspace_map as the consumer of the returned projectId. An agent can tell what this does without opening the schema.

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?

Explicitly says 'Start here' and routes the agent: projectId feeds traceable_workspace_map, organisationId feeds traceable_library_search and traceable_workspace_templates. It also explains when to pass organisationId (to disambiguate same-named projects across organisations). When-to-use and downstream alternatives are both spelled out.

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