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

The trailing 'Read-only' merely restates readOnlyHint=true and earns no credit, and openWorldHint=false is likewise untouched. What the description does add is a preview of the payload's contents (steps, client files, pointer to full instructions), which helps an agent decide whether to call it, but it says nothing about return format or size.

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?

One front-loaded sentence that lists the substantive contents efficiently. The only wasted clause is the closing 'Read-only', which duplicates an annotation and could be dropped without loss.

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 trivial read-only guidance tool with zero required parameters, a fully described schema, and no output schema to explain, the description covers what matters: what the agent will get back and that it is safe. The remaining gap is not clarifying how it differs from backroom_help_board.

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 100%: the single 'language' parameter is fully documented with its enum and python default. The description contributes nothing about language selection or how it changes the returned client files, so the baseline 3 holds.

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 names the specific content the tool returns: joining steps for The Back Room, the client files, and the location of full instructions. That is more concrete than a tautology, though the framing ('How to join...') leaves it implicit that this is a documentation/guidance retrieval tool rather than an action, and it draws no boundary against the sibling backroom_help_board.

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?

'In about a minute' hints that this is the fast onboarding path for a first-time user, which implies when to reach for it. However, there is no explicit when-to-use statement and no routing away from the topically adjacent backroom_help_board or backroom_doorman, so the agent must infer the choice.

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