configure_feed

Update RSS feed channel configuration by applying a partial patch for title, language, categories, TTL, and more. Use expected_revision to prevent overwriting concurrent edits.

Instructions

Update feed/channel configuration.

Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it only says 'Update feed/channel configuration.' It does not explain whether patches are partial or full replacements, what happens on expected_revision conflicts, or what side effects occur on the existing feed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is appropriately short and front-loaded, with no filler words. However, its extreme brevity veers toward under-specification rather than efficient completeness, leaving important behavioral and parameter context absent.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a mutation tool with a complex nested configuration object and an optimistic-concurrency parameter, yet the description does not explain patch behavior, revision handling, or effects on the feed. The output schema doesn't compensate for the missing operational context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description adds no parameter-level meaning whatsoever. It fails to mention the 'patch' object, 'expected_revision', or any of the FeedConfig fields, so an agent cannot infer parameter semantics from the description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Update') and resource ('feed/channel configuration'), making the tool's core purpose clear and distinguishable from read-oriented siblings like get_feed. However, it doesn't elaborate on the configurable aspects or patch semantics, so it stops short of a fully differentiated definition.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus alternatives such as rebuild_feed or update_entry, nor any mention of prerequisites or the expected_revision mechanism. The description implies a configuration mutation context but provides no explicit when-to-use instructions.

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