nexo_continuity_compaction_event

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

With no annotations, the description carries full burden. It indicates a persist (write) operation but omits side effects, idempotency, conflict behavior, or required permissions. There is no contradiction with annotations because none exist.

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 a single sentence, which is concise but at the cost of providing necessary detail. It front-loads the verb but lacks structure to aid quick comprehension.

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 no annotations, no output schema, 0% schema coverage, and a complex tool with 5 parameters and many siblings, the description is severely incomplete. It fails to explain what a compaction event is, how to construct the event, or what the result of persisting it entails.

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 input schema has 5 parameters with 0% coverage (no descriptions). The description does not explain any parameter's meaning or usage, such as what 'payload' or 'event_type' should contain. It adds no value beyond the parameter names.

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 specifies a clear verb ('Persist') and resource ('compaction-related continuity event'), and indicates the target is the 'canonical snapshot stream'. This distinguishes it from sibling tools like nexo_continuity_audit or nexo_continuity_snapshot_write by emphasizing compaction, though it relies on domain jargon.

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?

No guidance is provided on when to use this tool versus other continuity or snapshot tools. There is no mention of prerequisites, alternatives, or when not to use it, leaving the agent without decision context.

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