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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds the event taxonomy and the newest-first ordering, which is genuinely useful, but it doesn't define the scope of "recently" (time window, workspace-wide vs. object-scoped) or whether entries can be truncated.

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 with no padding, and the ordering constraint is placed at the end where it reads naturally. The leading "The log:" fragment is slightly awkward but does front-load the concept.

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?

The tool is simple (zero required params) and an output schema exists, so return values need no explanation. However, the undefined scope of "recently" — no timeframe, no indication of whether the log spans the whole ontology or a single resource — is a real gap for an agent deciding whether this answers its question.

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% and the single limit parameter is documented in-schema, so the baseline is 3. The description's "newest first" restates what the schema already says about ordering and adds no new meaning about bounds or defaults.

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 names the resource (a change log) and enumerates the event types it covers — added, changed, certified, deleted — plus the ordering, which is enough to tell it apart from siblings like search or get_term. The phrasing "The log:" is fragmentary rather than a clean verb+resource statement, but the intent is unambiguous.

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?

There is no when-to-use guidance: nothing says whether to reach for this versus search, get_term, or check_readiness when investigating recent activity, and no prerequisites or exclusions are stated. Usage is only inferable from the word "log."

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