open_room

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

No annotations are supplied, so the description carries the full behavioral burden. It discloses the bonding precondition and that the room is 'sealed' (implying privacy), but says nothing about idempotency, failure modes when a party is unbonded, cost, or what state is created — meaningful gaps for a state-creating operation.

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?

Two short sentences, zero waste, with the action and its input front-loaded before the precondition. Nothing is padded or repeated.

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 simple one-parameter tool with no output schema and no annotations, the description covers the action and the main precondition. However, it omits what the call returns or creates (room id, state) and what happens on precondition failure, leaving the agent under-informed for an operation that establishes shared state.

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 coverage is 0% and the single parameter has no schema description, so the description must compensate. It clarifies that the parameter is the counterparty's agent id (as opposed to a room id or self id), which is useful, but adds no format, lookup, or validation detail beyond that.

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+resource ('Open a sealed negotiation room') and names the key input ('counterparty agent id'), so the action is unambiguous. It does not explicitly distinguish itself from siblings like open_escrow or send_message, but the resource name is distinctive enough to route the agent correctly.

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?

Provides a concrete precondition: 'Both agents must be bonded (active)', which tells the agent when this call can succeed. It names no alternatives or exclusions (e.g., what to do when a party is unbonded), so it stops short of full when/when-not guidance.

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