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

No annotations are provided, so the description carries the full behavioral burden. Beyond the word 'Resume', it says nothing about side effects (e.g. whether outreach immediately resumes sending), idempotency when the channel is already active, return values, or authorization requirements.

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 front-loaded sentence with the verb and object first and no filler. It is efficient, though it errs on the side of underspecification rather than wordiness.

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?

With no output schema, no annotations, and 0% parameter description coverage, the definition leaves key information missing for a mutating tool: what 'id' refers to, what state change occurs, and what happens on error or repeat invocation.

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 0%, so the description must compensate for both parameters. It hints that 'channel' is a subordinate piece of a campaign, but leaves the critical ambiguity of 'id' unresolved — an agent cannot tell from the text whether 'id' is the campaign id or a channel id. The enum values are only documented in the schema.

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 (a paused channel on a campaign), which is clear enough to distinguish it from sibling pause_channel. However it does not explicitly name the counterpart tools (pause_channel, pause_campaign) or clarify how the campaign-level vs channel-level resume differ.

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?

The phrase 'a paused channel' implies the precondition that the channel must already be paused, which is a minimal form of usage guidance. There is no explicit statement of when to use this versus pause_campaign/pause_channel, nor any note about required permissions or ordering.

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