jar_preset_apply

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

No annotations are provided, so the description carries the full behavioral burden. It does not say whether edits are written to disk, whether they require an open jar session, whether the operation is reversible (the schema's 'reverse' flag hints at it but the description never explains it), or what happens if the preset is missing.

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?

One sentence, front-loaded with the action and resource, with zero filler. It is efficiently written, though its brevity is closer to under-specification than true conciseness for a mutation tool.

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 mutation tool with no annotations, no output schema, and an involved jar-editing workflow, this is too thin. It omits whether a jar/session must be open, whether a repack step follows, and what the result state is – all things an agent needs before invoking it.

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 100% – session_id, preset_name and reverse are each documented in the schema. The description adds no syntax, format, or scoping detail beyond that, so the baseline 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?

The description gives a specific verb+resource: 'Apply a saved preset of constant edits.' An agent can distinguish this from generic jar editing tools, but it never names or contrasts with its obvious siblings jar_preset_save and jar_preset_list, leaving the preset workflow implicit.

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?

There is no when-to-use guidance, no prerequisites (an open session, a previously saved preset), and no mention of the sibling tools that create and enumerate presets. The agent must infer that a preset must already exist via jar_preset_save.

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