esxi_firewall_manage

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

Annotations already declare destructiveHint=true, idempotentHint=false, and readOnlyHint=false, so safety profile is carried by structured data. The description adds real context beyond that: preview defaults, host-pinning via expected_host, write-toggle dependencies, and idempotency via request_id. It still does not explain what the destructive default policy change affects or the semantics of allow_disruption/allow_protected_impact gating, so it is good-but-incomplete rather than rich.

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 dense sentences with no filler and the action list is front-loaded, but the prose packs multiple distinct concepts (preconditions, host constraint, toggles, dedup) into a single run-on clause, which hurts scannability.

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?

An output schema exists so return-value explanation is not required, and annotations cover the safety profile. Given 9 params at 0% schema coverage and a destructive mutation, the description is adequate but leaves too many parameters and blast-radius details undocumented for full completeness.

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 0% and there are 9 parameters, so the description must compensate — it names expected_host, write toggles, and request_id but leaves action, dry_run, arguments, and the three allow_* impact flags unexplained. It provides partial compensation, warranting the baseline-ish 3, but falls well short of the full burden for a 9-param destructive tool.

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+resource (firewall management) and enumerates the operations (enable, disable, rules_update, default_policy), which distinguishes it from sibling *_manage tools like esxi_network_manage. However, it never contrasts itself against siblings like esxi_host_manage or esxi_options_manage, and the enumerated actions appear only in prose, not in any schema enum.

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?

Mentions a precondition workflow ('先 resource_schema/get 和默认预览') and repeat-execution protection via request_id, which implies context. But there is no explicit when-not-to-use guidance and no named alternative sibling; usage is implied rather than prescribed.

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