fix_commands

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

No annotations are provided, so the description carries full burden. It mentions that indexes refer to the 'current command list BEFORE any fixes are applied', which adds some behavioral context about ordering. However, it lacks critical details like whether this is a destructive operation, permission requirements, error handling, or what happens to other commands not mentioned, making it insufficient for a mutation tool.

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 two sentences with zero waste: the first states the purpose and actions, the second clarifies index behavior. It's front-loaded and appropriately sized, with every sentence adding value.

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?

Given no annotations, no output schema, and low schema description coverage (50%), the description is incomplete. It doesn't cover behavioral traits like side effects, return values, or error conditions, and parameter details are lacking. For a mutation tool with nested objects in 'fixes', this is inadequate.

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 50% (only 'test_id' and 'index' have descriptions). The description adds no explicit parameter information beyond implying 'fixes' involve actions on commands. It doesn't explain the semantics of 'command', 'target', or 'value' fields, nor does it clarify how actions map to parameters, failing to compensate for the low coverage.

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 clearly states the verb ('apply targeted fixes') and resource ('commands in a test'), with specific actions listed ('update, remove, or insert at specific indexes'). It distinguishes from siblings like 'add_commands' or 'clear_and_replace_commands' by emphasizing targeted fixes at indexes rather than bulk operations, though it doesn't explicitly name alternatives.

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 usage for modifying existing command lists in tests, with context about index referencing 'BEFORE any fixes are applied'. However, it doesn't explicitly state when to use this versus alternatives like 'add_commands' or 'clear_and_replace_commands', nor does it mention prerequisites or exclusions, leaving guidance incomplete.

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