get_event_series

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

With no annotations, the description carries the full burden, and it does add real behavior: the HTTP verb/endpoint (GET /series/{id}/) implies a non-mutating read, and it explicitly states the required Authorization: Bearer PERSONAL_OAUTH_TOKEN header. However it says nothing about what happens on a missing/invalid ID, permission scope beyond the header, or rate limits.

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 purpose sentence is front-loaded and the ENDPOINT / AUTHENTICATION blocks are easy to scan. The labeled blocks are slightly formulaic but every line carries information, with no filler.

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 single-parameter read endpoint with a fully described schema, the definition supplies the missing operational context an agent needs: the endpoint path and the exact auth header. It is not exhaustive about errors or the returned payload, but no output schema exists and the tool is simple.

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 description coverage is 100% and there is only one required parameter, so the schema already documents event_series_id fully. The description adds only the phrase 'by ID' and no format or example beyond that, which is the expected baseline.

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 and resource ('Retrieve parent Event Series by ID') and even defines the resource ('repeating Event with multiple dates'). It does not explicitly contrast with the nearest sibling (list_events_by_series), so it stops short of a 5.

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?

There is no when-to-use guidance and no mention of alternatives such as list_events_by_series or get_event. The only inference available is that you must already hold an Event Series ID, which is implied by the schema rather than stated.

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