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

No annotations at all, so the description carries the full behavioral burden. It implies a read but says nothing about ordering (chronological or not), whether the timeline is truncated by limit, whether entries are immutable, or what each entry contains — significant gaps for a log-reading tool with zero annotation coverage.

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 tight sentence with the resource front-loaded and no filler. It is efficient, though slightly telegraphic given how much behavioral context is missing.

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 two-parameter read tool with a fully documented schema and no output schema, the minimum is met, but with no annotations the description should have covered read-only semantics, ordering, and entry shape. It leaves an agent guessing about what a 'worklog entry' actually returns.

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% — site_id is documented as coming from list_sites and limit's default/max are stated in-schema. The description adds nothing beyond the schema, so the baseline 3 applies.

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?

Specific verb + resource: 'Read the site's intervention timeline', with a parenthetical clarifying that entries are recorded by AI or humans. That content hint helps separate it from siblings like get_events or list_accesses, though the description never names those siblings 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 implied by the parenthetical (an audit/history of interventions) but there is no explicit when-to-use statement, no exclusion against get_events/get_findings, and no guidance on whether this complements record_action. An agent must infer the routing itself.

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