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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint=false, so safety is covered. The description adds nothing beyond that: no mention of pagination behavior, result ordering, or the timezone/date semantics that actually matter here, leaving the behavioral picture thin for a search tool.

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 zero filler. Nothing redundant or padded.

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 and the input schema is well documented, so return values need not be explained. Still, for a 6-parameter search tool sitting among many search_* siblings, the description omits the differentiation and temporal-scope cues an agent needs to select it confidently.

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 83%, so the schema already documents date, before/after, query, tags, and limit with useful guidance (including the anti-probe note on limit). The description adds no parameter meaning at all, so baseline 3 is appropriate.

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 (Search) and resource (official AfroTech 2026 conference agenda/sessions) with a scope qualifier (official, tracked by Afrotech.guide). However, it does not distinguish itself from near-identical siblings such as search_events, search_guide, or search_people, leaving ambiguity about what a 'session' is versus an 'event'.

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 gives no when-to-use guidance, no exclusions, and never names an alternative sibling tool. An agent cannot tell from the text whether to call search_sessions or search_events for a given query.

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