read_eventlog

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

No annotations exist, so the description carries the full burden. It usefully discloses two real behaviors: the default severity filter (error/warning/critical, i.e. informational events are excluded unless requested) and newest-first ordering. It omits permissions needed, whether the read is live or a snapshot, pagination, and what happens with very large logs.

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?

A single front-loaded sentence with the key context in a compact parenthetical; nothing is wasteful. It is lean to the point of under-specification, but structure and sizing are appropriate.

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?

An output schema exists, so return values need not be explained. However, with no annotations and 0% schema coverage, an agent still lacks enough to call it confidently — no valid log_name list, no level syntax, no note on max_events behavior or required privileges.

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 0%, so the description must compensate, and it only partially does. It mentions the level and log_name defaults (which largely restate the schema 'default' fields) but never explains that level is a comma-separated list, what valid log_name values look like, or what max_events does — that third parameter is undocumented in both places.

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?

States a specific verb and resource ("Read recent events from a Windows event log") and adds scope detail (default log, default severity levels, newest-first ordering). It is clearly distinguishable from the sibling tools (services, processes, system info), though it never names them explicitly.

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?

Usage is only implied: the reader infers this is the troubleshooting/diagnostics tool for log inspection, but there is no explicit "use when..." statement, no mention of prerequisites (admin rights), and no routing to or away from any sibling.

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