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

Beyond the annotations it discloses the write scope (availability:write), the exact auth mechanism (vs_cap_… bearer, argument or injected header), a hard rate limit of 10 changes/day, audit-logging of every change for the human, and an explicit negative scope: it never moves funds, changes ownership, or touches keys. That is substantially more than readOnlyHint=false / destructiveHint=false conveys.

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 action is front-loaded in the first clause, followed by auth, constraints, and a safety boundary, with no filler sentences. It is dense with em-dash-separated asides and slightly long, but each clause carries operational value (auth, rate limit, ownership, non-destructive scope).

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 non-idempotent mutation tool with no output schema, the description covers everything an agent needs: authorization path, ownership prerequisite, rate limit, audit side effect, and the explicit boundary of what the call cannot do. No significant gap remains given annotations already flag the write semantics.

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 every parameter is already documented in the schema, including the boolean meaning and the token-omission case. The description's auth note largely restates the capability_token schema description, adding no new format or constraint information beyond 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 names a specific verb and resource (set the agent blockpage's open-for-work flag) and states the mode of execution: DIRECTLY, with no human tap needed. That distinguishes it from proposal-style siblings such as propose_page_update or stage_page_draft, so an agent can route correctly without opening a 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?

It gives the operative prerequisite (your human must own the agent page on-chain) and implicitly contrasts with approval-gated flows via 'no human tap needed'. It does not name an alternative tool to use when the prerequisite fails, so it stops short of full when/when-not routing guidance.

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