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

Annotations only declare readOnlyHint=false, destructiveHint=false and openWorldHint=false; the description adds real behavior on top: a 20 components/sections per batch ceiling, evidence bound to the version, and the rule that 'blocked' preserves an unresolved defect while 'static' must never hide an abandoned interaction. It stops short of explaining what happens on a version mismatch despite required expectedVersion/expectedPageVersion fields.

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 purpose is front-loaded and little space is wasted, but the text is a dense run-on with no structure separating the recording action, the decision rules, the interaction checklist and the batch limit. Some content (20-item cap) merely restates the schema's maxItems constraints.

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 write tool with no output schema and no schema descriptions on any of its five parameters, the description covers the decision model and batching but is silent on version-conflict handling, validation errors, and what a successful submission returns. An agent could construct the call, but not confidently predict failure modes.

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?

With 0% schema description coverage the description must carry parameter meaning, and it does explain decision semantics (native/static/blocked), the nativeBlockIds requirement, and the evidence requirements. It leaves the three required top-level identifiers unexplained — templateId, expectedVersion and expectedPageVersion — so the optimistic-concurrency contract an agent must satisfy is not conveyed.

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 opens with a specific verb and resource ('Enregistrer les composants réellement testés après correction dans l'éditeur'), so an agent knows this persists test outcomes rather than previewing or listing components. It is distinguishable from siblings like preview_components or search_components, though the distinction is implicit rather than stated.

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?

Usage is implied by 'après correction dans l'éditeur' and by the per-decision rules, which tell the agent which decision value to pick under which circumstance. However, no sibling tool is named as an alternative, and there is no explicit statement of when NOT to record (e.g., before a fix, or during preview).

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