Feature workflows in a Slack channel by specifying the channel and up to 15 workflow trigger IDs to highlight important workflows for team members.

Instructions

Add featured workflows to a channel.

trigger_idsYesWorkflow trigger IDs to feature, max 15 (e.g. ``["Ft0123", "Ft0456"]``).

Behavior2/5

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

With no annotations, the description carries the full burden. It states the basic action of adding but reveals no behavioral traits such as permissions required, idempotency, or what happens if a workflow is already featured. This is insufficient for safe usage.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no unnecessary words. It is front-loaded and efficient, though it could benefit from slightly more context without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simplicity of the tool and the existence of an output schema, the description still lacks important context such as permissions, the effect on existing featured workflows, and how this differs from 'set'. It is minimally complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already provides full coverage with descriptions for both parameters. The description does not add any additional meaning beyond 'add', so the baseline score of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'add' and the resource 'featured workflows' with the target 'channel', distinguishing it from sibling tools like 'list' and 'remove'. However, it does not explicitly differentiate from 'set', which might imply a similar operation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. The description only implies adding, but there are no when-not conditions or mentions of sibling tools like 'workflows_featured_set' that might be more appropriate for replacing the entire feature set.

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