slackbot_add_modals

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

There are no annotations, so the description must carry the full behavioral disclosure burden. It reveals only that the tool generates interactive modal workflows and is a Pro feature, leaving unspecified whether it writes files, requires configuration, calls an API, or has side effects.

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 short and front-loaded with the core action, and the parenthetical is not wasted words. However, it errs on the side of under-specification rather than genuine conciseness, since important operational details are absent.

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 and no annotations, the description is too thin for reliable agent invocation. It does not clarify what artifacts are generated, what 'Pro feature' means in practice, whether api_key is needed, or what the directory parameter should point to.

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 only 50%, and the description adds no parameter-level meaning. The directory parameter has a minimal schema description, but api_key is entirely undocumented in both the schema and the description, so an agent cannot infer how or whether to provide it.

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 'Generate' and a concrete resource, 'interactive modal workflows,' which distinguishes it from sibling tools like slackbot_generate_app and slackbot_add_commands. The parenthetical 'Pro feature' adds context about availability, though it does not explicitly contrast with alternatives.

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?

No guidance is given on when to use this tool versus alternatives such as slackbot_generate_app or slackbot_add_commands. The only contextual hint, 'Pro feature,' implies a plan restriction but does not explain when modal workflows should be generated or which sibling tools should be preferred.

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