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

With no annotations, the description carries the full burden and does so well: it discloses a separate administrative publish authorization requirement, DB-lock revision/membership checks, preservation guarantees (other tags/relations, article text/authorship/URLs/publication state), and idempotency semantics (identical retries reuse arguments, changed arguments conflict, ambiguous pending writes fail closed). It even names the return payload.

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?

Front-loaded with the core purpose, and virtually every sentence carries distinct operational information (prerequisites, preservation, retry behavior). The sentences are dense run-ons that pack multiple clauses, which slightly hurts scanability but wastes little.

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 complex mutation with no annotations and no output schema, the description covers authorization, locking, preservation, idempotency, and return shape. Remaining gaps are minor: how to obtain the administrative token and concrete examples of expected_version/draft_revision values.

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 0% and all five params are undocumented in the schema, so the description must compensate. It gives partial semantics for four of them (fresh expected_version, exact saved draft_revision, new unique request_id, slug) but never explains token, nor the format/origin of draft_revision or expected_version.

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 with precise scope: 'Publish ONLY one saved materials section and its selected article memberships.' The 'ONLY one saved materials section' framing cleanly distinguishes it from siblings like online_article_publish and online_content_edit without the agent needing to open either schema.

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?

Gives a clear prerequisite workflow ('Read/get and preview RU/EN first') and an explicit exclusion ('Never activates/publishes an article or other online-page drafts'). It stops short of naming the sibling tools (online_material_section_preview, online_material_section_save) it should be paired with, so routing is inferred rather than stated.

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