Connect Redis Pub/Sub bus

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

Annotations indicate a write operation (readOnlyHint=false) and non-destructive (destructiveHint=false), with which the description is consistent. However, the description adds little behavioral context: it mentions 'keyspace safety notes' and 'read-first operations policy' but does not explain side effects, whether existing components are modified, or what the scaffold actually does at runtime.

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 compact sentence with a meaningful list of features. It is front-loaded with the main verb and resource, and most words add value. However, the jargon-heavy phrasing ('adapter ingest', 'keyspace safety notes') could be clearer.

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?

With 12 parameters, no output schema, and sparse annotations, the description is incomplete. It does not explain the scaffold's purpose, configuration, return value, or how it integrates with the broader system. The high parameter count and low schema coverage make this description insufficient for an agent to use the tool confidently.

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 only 17% (name and parent_path have descriptions), so the description must compensate. It does not: none of the 12 parameters (e.g., stream_mode, adapter_mode, channel_root, database_index) are explained beyond their names. The phrase 'channel maps' hints at channel-related params but is too vague.

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 specific action ('Create a Redis Pub/Sub/Streams scaffold') and the resource. It lists key components (adapter ingest, channel maps, keyspace safety notes, read-first operations policy), which distinguishes it from sibling connect/create tools.

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 on when to use this tool versus alternatives like connect_mqtt_iot_bus or create_external_io. There is no mention of prerequisites, exclusions, or preferred use cases. The description only implies it is for creating a Redis scaffold.

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