Delete extensions

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

Annotations already declare destructiveHint and readOnlyHint, but the description adds important behavioral context by explaining the downstream effect on profiles (they lose the extension on next launch). This goes beyond the structured fields without contradicting them.

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 description is a single sentence that is precise and front-loaded with the primary action. It contains no filler or redundant information.

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 simple one-parameter delete tool with robust annotations, the description covers the essential effect on profiles. It could mention return behavior or permanence, but these are not critical given the simplicity and existing annotation coverage.

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 0%, so the description carries the burden for explaining parameter meaning. It does not mention 'ids' at all, leaving the agent to infer that they are extension identifiers. The schema itself only provides type and requiredness, so the description adds no value for parameter understanding.

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 uses the specific verb 'Remove' and clearly identifies the resource 'extensions from the workspace.' It also adds a meaningful consequence ('Profiles using them lose them on next launch') that distinguishes it from sibling tools like add_extension and list_extensions.

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?

The description implies the tool is for deleting extensions but does not explicitly state when to use this over alternatives or provide exclusions. The usage is clear from the name and context, but no explicit guidance is given.

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