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

The annotations already declare read-only, idempotent, non-destructive, closed-world behavior, so the description is not burdened with safety disclosure. It adds useful behavioral context beyond the annotations, including publishability conditions, the meaning of why_not, sandbox claim state, and the consequence that without publishing only drafts work.

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?

The description is compact and front-loads “Start here,” then packs the return context and decision guidance into a dense but purposeful block. It contains no filler, though the long parenthetical sentence is somewhat harder to scan than it could be.

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 zero-parameter, read-only introspection tool with no output schema, the description gives enough context to understand what information will be returned and how to use it. It covers organization identity, plan usage, publish eligibility, caps, and sandbox state, leaving no material gap for correct invocation.

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 to explain; per the rubric this establishes a baseline of 4. The description appropriately does not waste space documenting inputs.

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?

The description clearly states that this is the starting-point identity/context tool and enumerates what it returns: organization, plan, usage, publish eligibility, caps, and sandbox claim state. It is specific enough to distinguish it from the sibling tools, though it does not explicitly name or contrast any sibling.

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?

“Start here” gives explicit guidance that this should be called before other operations, and “Use can_publish to decide between drafting and scheduling” ties the output to a concrete decision. It does not state when not to use it or name alternative tools, but the primary usage context is clear.

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