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

Annotations already declare readOnlyHint=false, destructiveHint=true, and idempotentHint=false, so the mutation/safety profile is covered structurally. The description adds useful semantic context about what the settings actually govern (auto-publishing without review, self-building KB), but says nothing about what a change overwrites, whether it's reversible, or whether it needs elevated permissions. Adequate given annotations, but thin on mutation behavior.

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?

It is a single sentence with no padding, which is good, but the sentence is long, dense, and hard to parse due to nested parentheticals and the trailing phrase 'the limits per check and for the build'. The core action is not front-loaded — the reader must reconstruct 'update' from context.

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 destructive, non-idempotent mutation tool with no output schema, the description explains the settings domain but omits whether changes require specific permissions, their reversibility, or their effect on in-flight updates. It gives enough to understand the fields but not enough to invoke 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 88%, so the schema already documents field meaning and ranges; baseline is 3. The description loosely maps to parameters (engine choice, autoPublish, autoBuild, per-check and build limits) and adds conceptual framing, but it names no parameter directly and adds little syntax-level meaning beyond the schema.

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 enumerates what the settings control ('who writes the code-driven article updates... whether they publish without review... whether the knowledge base builds itself...') rather than stating the action. The verb 'update/change' exists only in the name and title, so the purpose is inferable but not crisply stated. It does implicitly distinguish this tool's domain from siblings, but an agent gets no explicit 'this changes settings X' statement.

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?

No when-to-use, prerequisites, or alternatives are given. With siblings like get_code_updates, edit_code_update, approve_code_update, and decide_code_update_batch, the description never clarifies when to reach for this tool versus those. Usage must be entirely inferred from the name.

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