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

Annotations already cover the key traits (destructiveHint=true, idempotentHint=true, not read-only). The description adds valuable context beyond them – protection semantics and the language-tab removal rule (empty content + language deletes the tab) – but omits permission requirements, overwrite/merge behavior for omitted fields, and error conditions.

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?

Efficient and front-loaded, but the 'Speech Style' language-tab explanation is dense and slightly convoluted, mixing main-content vs. tab semantics in one run-on sentence.

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?

Covers the core create/update-by-title flow and the trickiest parameter (language) well, but with no output schema and only 50% schema coverage, the description doesn't fully address 8-parameter complexity or return/error behavior.

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 50%, so the schema documents roughly half the 8 parameters (aiSees, content, language). The description reinforces content, isProtected, and language semantics, adding value over the schema for those, but leaves type/summary/entryId undocumented – partial compensation only.

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 (create/update) and resource (panel), with concrete example ('Speech Style') and the title-keyed semantics. It's clear against siblings like update_entry/update_world, though it doesn't explicitly name an alternative tool.

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?

Implies usage (upsert by title, language-tab behavior for Speech Style/Examples) but offers no explicit when-to-use vs. alternative like update_entry, and no prerequisites or exclusions.

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