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

Annotations already mark this as readOnly, idempotent, and non-destructive, and the description adds meaningful context beyond that: it reads SQLite data only, never generates or refreshes AI content, returned content is untrusted source data, and sermon digest counters may be placeholders unless verification succeeds. No contradiction with annotations.

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?

The description is longer than average but every sentence adds operational value: scope, contents, verification flag, sibling routing, trust boundary, and side-effect safety. It is well structured and front-loaded with the primary purpose, though it could be tightened slightly without losing meaning.

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?

With a single optional parameter, a full input schema, and an output schema present, the description covers everything an agent needs: default date behavior, timezone, return contents, verification caveat, safety/trust boundary, and where to go for sermon text. Nothing important is missing.

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 100% and the schema already explains that the date is optional and omitting it means today. The description adds the Europe/Warsaw timezone detailagingly but mostly restates what the input schema already provides, 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?

The description states a specific verb ('Load'), a precise resource ('the already-prepared public /dzisiaj briefing'), and the supported scope (today Europe/Warsaw or a selected YYYY-MM-DD date). It also names the returned content types just enough to distinguish it from sibling tools like get_sermon or get_announcements.

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?

It clearly states when to use the tool: for today's daily briefing or a chosen date. It explicitly routes to get_sermon for current sermon text, giving an alternative, though it does not discuss exclusions for other siblings such as get_ai_study or get_announcements.

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