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

Annotations already declare readOnlyHint and idempotentHint, and the description reinforces rather than repeats that with "Read-only." It adds genuinely new behavioral context not in annotations: the inventory that the response spans databases, rules with per-database overrides, and alert channels, plus the security-relevant guarantee that channel URLs are never returned.

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 dense sentence, front-loaded with what the tool returns, followed by a short scope note and a two-word safety tag. The parenthetical inventory is long but every element describes a distinct part of the payload, so little could be cut without losing return-shape information.

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?

There is no output schema, so the description carries the burden of describing the return value, and it does so in concrete terms down to rule fields and channel fields. Remaining gaps are minor: it does not state how sensitive columns are identified (names vs values) or whether other secrets are redacted beyond the channel URL.

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 is no parameter meaning to convey and the baseline of 4 applies. The description correctly avoids inventing filtering options that do not exist.

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 configuration this workspace has now" combined with an explicit enumeration of the returned contents (enforcement mode, SQL action, telemetry, databases with sensitive columns, rules, alert channels) makes the resource and its scope unambiguous. It does not explicitly contrast with siblings such as list_rules or show_rule, which return overlapping subsets, so it falls just short of full sibling differentiation.

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?

Usage is only implied: an agent can infer this is the full-snapshot read used before plan_config_change, and the tie-in to plan_config_change hints at that workflow. There is no explicit when-to-use or when-not-to-use statement, and no guidance on choosing this over list_rules/show_rule for narrower needs.

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