Load project into editor

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

Annotations already declare readOnlyHint=false and idempotentHint=false, but the description adds the key consequence the annotations cannot express: it replaces the current editor config. That is precisely the fact an agent needs before calling. It stops short of saying whether unsaved changes are recoverable or what happens if the id is invalid.

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?

Three short sentences, purpose and mutation warning front-loaded, workflow next. The internal function-name aside (setFirmwareConfig(getFirmwareById(id)) + setConfigType) is implementation detail that costs reading effort without helping an agent decide or call, but the rest 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?

For a single-parameter mutation with no output schema, the description covers purpose, mutation effect, and the follow-up workflow. Only missing pieces are failure behavior (unknown id) and whether the prior editor state is lost or restorable.

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% and the id parameter already documents its origin ('from project_list'), so the description adds no new parameter meaning. The parenthetical getFirmwareById(id) hints at lookup semantics but repeats little of practical value. Baseline 3 applies when the schema carries the parameter burden.

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+resource ('Load a project's config into the app's firmware editor store') and disambiguates scope from siblings by tying it to the user action 'the same thing the app does when you open a project'. An agent can distinguish it from project_open_editor and firmware_config_get from the text alone.

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?

Gives an explicit call sequence: load, then firmware_config_edit to change parameters, then project_save to persist. It names both follow-up siblings and their roles, so there is no ambiguity about ordering or alternatives.

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