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

The annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=true, so the description's job is to explain the consequences, and it does: re-enabling permits scheduled export and submission to resume, 'including changes to live listings.' It also mandates user confirmation before enabling, which is valuable given the open-world destructive profile. It does not discuss any rate limits or auth requirements, which keeps it at a 4 rather than 5.

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?

It is dense and front-loaded: the action, then the return shape, then the conditional usage, then parameter provenance, then the confirmation caveat. Every sentence contributes, though the explicit literal return-shape dump is slightly verbose for a tool with no output schema.

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?

No output schema exists, and the description compensates by stating the returned fields (feedId, action, status, feedStatus, enabled). It covers purpose, parameters, side effects, and the safety caveat, which is nearly everything needed for a two-parameter state-change tool. Only the project_id semantics and the distinction from restore_feed are missing.

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%, so the description must carry the meaning, and it does for the required feed_id ('from list_feeds / create_feed') and marks project_id as OPTIONAL. It does not explain what project_id scopes or when it should be supplied, so the optional parameter remains slightly under-explained.

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?

Opens with a specific verb plus a parenthetical gloss ('Resume (re-enable) a paused feed'), which unambiguously identifies the resource and the state transition from paused to enabled. It is clearly the inverse of pause_feed, but it does not differentiate itself from the sibling restore_feed, leaving a small ambiguity among the feed-state tools.

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?

Gives an explicit triggering condition: 'Use this when the user wants a paused feed to export again.' It also supplies a procedural precondition ('Confirm with the user before enabling'), which is real operational guidance. It stops short of naming alternatives such as restore_feed or submit_feed for the when-not case.

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