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

Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false, so the safety profile is covered. The description adds genuinely new behavior: the downstream effect (forms that send to it stop) and the fact that it always returns a human approval link, which is not derivable from annotations.

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?

Three tight sentences, front-loaded with the action and its scope, then the side effect, then the reversibility/approval behavior. No filler and every sentence contributes distinct 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?

For a destructive mutation with annotations and an output schema, the description covers impact, scope (project vs workspace), reversibility, and the approval-link return path, so an agent can call it confidently. Missing only explicit sibling routing, which is minor given the rich behavioral detail.

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?

The single 'provider' parameter has 0% schema description coverage, so the description must carry the load. It does so by naming all four enum values (Notion, Slack, HubSpot, Discord), matching the schema enum exactly and making clear what each accepted value means.

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?

States a specific verb ('Detach') and resource (the project's Notion/Slack/HubSpot/Discord account), and clarifies the scope is project-level rather than workspace-level. However, it never distinguishes itself from the similarly named sibling fillo_disable_integration or from fillo_remove_connection_account, leaving the agent to infer which of the near-synonyms to pick.

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?

Usage is implied rather than stated: the line 'The workspace account stays available to other projects' hints at the contrast with a workspace-wide removal, but no explicit when-to-use or 'use X instead' guidance is given. Against siblings like fillo_disable_integration the agent must guess.

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