adb_ota_history

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

No annotations are provided, so the description carries the burden. It describes a read-only listing operation but does not explicitly state that the tool makes no modifications, nor does it mention permissions, rate limits, or error scenarios. The 'list' and 'highlights' terms suggest non-destructive behavior, but transparency is minimal.

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 two sentences, front-loaded with the core purpose, and every word adds value. No fluff or redundancy.

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 simple tool with one optional parameter and no output schema, the description covers the main functionality: listing fingerprints and highlighting changes. However, it could mention the return format (e.g., a list of fingerprints with timestamps) to be fully self-contained.

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 100%, with the one parameter 'device' already well-documented in the schema. The description adds little beyond restating 'for a device', so it does not significantly enhance parameter meaning beyond what the schema provides.

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 tool lists saved system fingerprints for a device and shows version progression with change highlights. It distinguishes from sibling tools like 'adb_ota_check' (which likely checks for updates) and 'adb_ota_fingerprint' (current fingerprint) by focusing on historical data.

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 implies the tool is for viewing historical fingerprints but does not explicitly guide when to use it over alternatives like 'adb_ota_check' or 'adb_ota_fingerprint'. No when-not-to-use or exclusion criteria are provided.

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