group_session_create

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

Annotations only provide readOnlyHint=false and destructiveHint=false, which are consistent with 'Create'. However, the description adds no further behavioral context such as permissions required, side effects, idempotency, or what 'Free.' means. The agent is left without important behavioral cues beyond the fact that it creates a group.

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?

The description is two sentences, front-loaded with purpose and result. It is concise but includes an ambiguous 'Free.' that could be clarified or removed. Overall, 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?

Given the complexity (7 parameters, no output schema, no helpful annotations), the description is too sparse. It does not explain the optional parameters (theme, objective, ritual_strip, response_mode, response_profile) or their use cases, leaving the agent without sufficient context to decide when to use them.

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 schema covers 100% of parameters with descriptions, so the description is not required to add extra parameter semantics. It generally aligns with 'linking N existing sessions' but adds no additional meaning beyond what the schema provides.

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 clearly states the tool's purpose: 'Create a multi-agent coordination group linking N existing sessions.' It specifies the return value ('Returns group_id') and identifies subsequent tools that use this group, distinguishing it from sibling group tools.

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?

The description provides minimal guidance: it mentions the group can be used for subsequent calls (team_recovery_alignment, peer_witness_bidirectional, group_therapy_round) but does not specify when to use this tool vs alternatives like create_dyad, nor does it give conditions for use or non-use.

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