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

The critical behavioral surprise is disclosed: this tool produces instructions only and performs no navigation or mutation on its own. That is consistent with readOnlyHint=true, destructiveHint=false and openWorldHint=false, and it adds the actionable handoff (use cotlet_browser_* next). It also pre-empts a common wrong assumption by noting Tradify publishes no API, developer docs or webhooks, explaining why browser automation is the path.

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?

Front-loaded and tight at three sentences, with the load-bearing fact (returns how-to, opens nothing) placed early. Minor waste in the marketing-flavored 'from ChatGPT, Claude or any AI agent' and the dated parenthetical about the API check, though the latter does justify the browser-based approach.

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 zero-parameter, no-output-schema, read-only tool, the description supplies everything needed: what is returned, that nothing is executed, and which sibling tools complete the task. The one gap is that with no parameters it never explains how a specific staff/date request is conveyed, leaving the agent to realize the returned procedure is generic.

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 tool takes zero parameters, so the baseline is 4 and there is nothing for the description to disambiguate. It does implicitly cover the empty schema by explaining that the output is generic step-by-step guidance rather than a targeted command.

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 makes the real behavior explicit: it returns step-by-step Tradify navigation instructions (screens, buttons, fields) rather than performing the scheduling. This distinguishes it from cotlet_browser_* tools, which actually act. The only weakness is the lead clause 'Schedule staff in the user's own Tradify account', which momentarily reads like a mutation until the second sentence corrects it.

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?

Clear workflow guidance: call this to get the procedure, then execute it with the cotlet_browser_* tools in the user's Tradify Cloud Browser. It also states the negative condition implicitly ('opens nothing by itself'), preventing the agent from expecting side effects. It does not contrast with the sibling cotlet_app_guide, so there is residual ambiguity about which guide tool to pick.

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