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

Annotations already declare it a non-read-only, idempotent, non-destructive, closed-world mutation, so the safety profile is covered. The description adds only the 'privacy-filtered project metadata' qualifier about the payload; it says nothing about required permissions, the effect of the update, or what happens to existing panels. With annotations present, this modest added context lands at 3.

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 front-loaded sentence with no padding or redundancy, which is appropriate sizing. It is however dense with domain jargon ('curate scope panels') that slightly reduces immediate comprehensibility.

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 mutation tool with five parameters, a nested object, and no output schema, one sentence is insufficient: it never explains what curate scope panels are, when the tool should be used, or the expected effect. Annotations cover idempotency but cannot substitute for this operational context.

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 description coverage is 100%, so the schema already documents projectId, idempotencyKey, and the bounded 'details' object. The description only gestures at 'privacy-filtered project metadata' without clarifying the details fields or the optional sessionId/executionId semantics, so it does not exceed the baseline.

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 has a definite verb ('Update') and resource ('hosted curate scope panels') plus a data-qualifier ('privacy-filtered project metadata'), so the agent can grasp what the tool does. It does not, however, distinguish this tool from siblings like scope_write, claim_map_scope, or release_map_scope, which also touch scope state.

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?

There is no when-to-use, when-not-to-use, or alternative-tool guidance. The agent is left to infer from the name alone whether this supersedes scope_write or the map-scope tools; nothing in the text routes it.

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