athena_party_join

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

The description discloses that goal ownership, role, capabilities, task relation, and current board claim are 'frozen' into the shared party record, indicating immutability after joining. However, it does not mention side effects like reversibility, permissions, or failure behavior, leaving significant behavioral aspects undocumented.

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 sentence that is front-loaded with the core action and includes a meaningful constraint (Message Board V1). No wasted words.

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 tool with 7 parameters and no output schema, the description is thin. It does not describe return values, error conditions, or the full effect of freezing on subsequent operations. The unqualified reference to 'Message Board V1' and the ambiguous 'current board claim' leave gaps.

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%, so the description carries the burden. It mentions 'role', 'capabilities', 'task relation', and vaguely references 'goal ownership' and 'current board claim', but does not explain parameter purposes, allowed values, or the meaning of goal_refs, party_id, agent, or remote. The enum in task_relation is undefined.

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 explicitly states the action ('Join an existing party') and the resource ('shared party record'), and clarifies a prerequisite (already present on Message Board V1). It distinguishes from siblings like athena_party_form by indicating it joins an existing party.

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?

It provides a clear precondition ('while already present on Message Board V1') and implies the tool is for joining rather than forming (sibling athena_party_form). However, it does not explicitly name alternatives or state when not to use.

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