upstash_redis_set

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

No annotations provided, and the description does not disclose behavioral traits beyond the basic operation. Does not mention idempotency, side effects (e.g., overwriting existing keys), error conditions, 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?

One sentence, concise, but lacks substance. Every word should earn its place; here, the sentence is too generic and does not provide useful context beyond the name.

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?

Despite moderate complexity (6 params, Redis context), the description is minimal. No output schema, no explanation of return values, success/failure indicators, or behavior with existing keys. Insufficient for reliable agent execution.

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 has 6 params with only 33% description coverage (value and ex described). The description provides no additional parameter information; it does not explain required fields like api_key, email, db_id, or key, which are critical for agent usage.

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?

Description clearly states the action 'set', the resource 'key-value pair', and the context 'Upstash Redis database'. It is specific and distinguishes from sibling tools like upstash_redis_get, del, incr, list_keys.

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. No mention of prerequisites, when not to use, or recommended scenarios. Simply states the operation.

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