pennylane_unletter_lines

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

Annotations already declare readOnlyHint=false, idempotentHint=true and destructiveHint=false, so the mutation/idempotency profile is covered. The description adds the corrective-reconciliation context but discloses nothing about required permissions, whether unrelated line data is affected, or reversibility beyond what annotations imply. 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?

Two short sentences, front-loaded with the action and followed by the use case. No filler; every clause earns its place.

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 an output schema present, annotations carrying the safety profile, and 100% schema parameter coverage, the description covers what an agent needs to call the tool correctly. Only the absence of explicit sibling routing keeps it short of full completeness.

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 100%: line_ids and the strategy option ('none' vs 'partial') are fully documented in the schema, including the behavior of each strategy. The description adds no parameter meaning of its own, so the baseline of 3 applies.

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: removing the matching/lettering ('lettrage') from entry lines, plus the corrective purpose ('corriger un rapprochement erroné'). It is clear what the tool does, though it never names its inverse sibling pennylane_letter_lines to sharpen the distinction.

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 gives one scenario where the tool is useful ('to correct an erroneous reconciliation'), which is genuine implied guidance. However it states no conditions for when-not to use it and never points to the counterpart tool (pennylane_letter_lines) or prerequisites, leaving the agent to infer routing.

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