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

Beyond the annotations, the description discloses significant side effects: the feed posts new items as the resuming member, requires the posts.draft permission, checks within a minute, and returns 404 for out-of-workspace ids. It also warns about recurring pause if the cause is not fixed, which is valuable behavioral context for a destructive/open-world operation.

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 description is front-loaded with the core action and proceeds through confirmation, permission, pause-reason caveats, and workspace scoping without filler. Every sentence contributes actionable 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?

Given the output schema and annotations, the description covers all key gaps: side effects, permissions, required confirmation, edge cases around pause reasons, and workspace scoping. An agent has enough to decide whether and how to call it correctly.

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 both id and workspaceId are already documented. The description only adds scoping detail (ids outside the workspace return 404) and does not explain parameter semantics beyond the schema. Baseline 3 is appropriate.

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 states a specific verb (resume) and resource (paused RSS feed), and immediately clarifies the effect: clearing the pause reason and checking the feed within a minute. This clearly distinguishes it from sibling tools like pause_rss_feed and create_rss_feed.

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 explicitly says to confirm with the user first and gives conditions for when not to resume directly (pause reasons ACCESS_LOST, SUBSCRIPTION_INACTIVE, CONNECTION_REMOVED). It does not name an alternative sibling tool for those cases, but the when-to-use context is clear.

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