apply_updates

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

Discloses the mutation nature (download and install) and scope (engine + corpus). However, with no annotations, it fails to mention potential side effects like service restarts, rollback options, or status when already up-to-date.

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 is concise and front-loaded. Every word earns its place, though could be slightly more structured with a brief note on usage.

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 tool with no parameters and an output schema, the description is clear enough. However, it lacks mention of preconditions like checking for updates first, which would improve completeness given sibling tools.

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?

No parameters exist, so schema coverage is 100%. Description adds no param info, which is acceptable per baseline rule (score 4).

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 verb-adverb (download and install) and resource (latest validated release, engine + corpus). It is specific and distinguishes from sibling tools like 'check_for_updates' (check only) and 'update_corpus' (corpus only).

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 indication of when to use this tool versus checking first with 'check_for_updates' or other alternatives. The 'now' implies immediacy but lacks prerequisites or context for safe invocation.

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