POST /events/:eventID/rsvp — RSVP to a free event
RSVP to an event that uses free RSVP (not ticketed). Only works for events with rsvpEnabled: true.
⚠️ WRITE operation: this mutates your DC account data.
| Name | Required | Description | Default |
|---|---|---|---|
| status | Yes | RSVP status | |
| eventID | Yes | The event ID |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden and explicitly states '⚠️ WRITE operation: this mutates your DC account data.' This clearly informs the agent of the mutation behavior. There is no contradiction with annotations.
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 concise: three sentences with no wasted words. It front-loads the HTTP method and resource, then adds key conditions and a warning. Every sentence earns its place.
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 tool with only 2 required parameters and no output schema, the description is reasonably complete. It explains preconditions (free event, rsvpEnabled) and the mutation nature. It could mention expected outcomes (e.g., confirmation, error handling) but is adequate given the tool's simplicity.
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 100%, so baseline is 3. The description adds no additional meaning beyond the schema: it mentions eventID in the path and status implicitly, but does not explain values or formats. The schema already provides enum descriptions for status, so the description adds negligible value.
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: 'RSVP to a free event' with the HTTP method and endpoint. It distinguishes from siblings by specifying 'free RSVP (not ticketed)' and the condition 'rsvpEnabled: true', differentiating it from event_meetup_rsvp and virtual_event_rsvp.
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 clear guidelines: 'Only works for events with rsvpEnabled: true' and 'not ticketed'. It implicitly tells when to use this tool (for free RSVP events) and when not (ticketed/meetup/virtual events). However, it does not explicitly mention alternatives like event_meetup_rsvp.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Despite the large number of tools, each has a detailed description that clearly distinguishes its purpose. Minor potential overlaps (e.g., search vs. resource-specific search, own vs. other's agenda) are well documented, so an agent can differentiate them.
Tool names follow a consistent verb_noun or resource_subresource_action pattern in snake_case. A few tools are just nouns (e.g., 'alerts', 'announcements'), but these are top-level listing endpoints; overall the naming is predictable.
85 tools is very high for a single server, making it difficult for an agent to efficiently explore and select the right tool. While each tool seems justified for the broad domain, the count feels overwhelming and could be streamlined.
The tool surface covers most major areas (events, trips, chapters, rooms, search, profile, etc.) with CRUD or lifecycle operations. However, the lack of a 'send message' tool for rooms is a notable gap, and some resources (e.g., events) are read-only on creation/update, limiting agent workflows.
