get_qrcode_history

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

No annotations provided, so the description bears full burden. It states ordering ('newest first') but lacks details on response structure, read-only nature, or potential side effects. It does not disclose if history includes all replacements or only certain ones.

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?

Single sentence, concise, no filler. However, it could be restructured to front-load key information more clearly, e.g., starting with 'Retrieve file-replacement history...'

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?

Output schema exists (not shown), so return value explanation is unnecessary. However, for a tool with one parameter, the description is adequate but lacks usage context and parameter clarification, making it minimally complete.

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 coverage is 0% with only 'id' as an integer parameter. The description does not explain what 'id' refers to (presumably the QR code ID). With low schema coverage, the description could add meaning but does not.

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 it returns file-replacement history for file-backed QR codes, ordered newest first. It distinguishes from siblings like get_qrcode (current info) and download_qrcode_file (file download), though the verb is implicit.

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 context for file-backed QR codes vs. other types.

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