get_series_updates

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

No annotations are provided, so the description carries full burden for behavioral disclosure. The description 'fred/series/updates' reveals nothing about whether this is a read or write operation, what permissions might be needed, rate limits, pagination behavior, or what kind of data is returned. It fails completely to describe any behavioral characteristics of the tool.

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?

While technically concise (just three words), this is under-specification rather than effective conciseness. The description doesn't communicate essential information, so its brevity is a deficiency rather than a strength. A single meaningful sentence would be more valuable than this minimal path notation.

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, no annotations, and complex sibling relationships in the FRED API, the description is completely inadequate. While an output schema exists (which helps with understanding returns), the description fails to explain what the tool does, when to use it, or how parameters affect behavior - leaving the agent with insufficient context to use this tool effectively.

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?

With 7 parameters and 0% schema description coverage, the description provides no information about any parameters. It doesn't explain what 'realtime_start/end' versus 'start_time/end_time' mean, what 'filter_value' controls, or how 'limit' and 'offset' affect results. The description fails to compensate for the complete lack of parameter documentation in the schema.

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 'fred/series/updates' is essentially a tautology that restates the tool name in a path format. It provides no meaningful information about what the tool actually does - no verb indicating the action, no explanation of what 'updates' refers to, and no distinction from sibling tools like get_series or get_series_observations.

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 absolutely no guidance on when to use this tool versus alternatives. With numerous sibling tools in the FRED API ecosystem (like get_series, get_series_observations, search_series), there is no indication of what specific problem this tool solves or when it should be selected over other series-related tools.

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