kconfig_set

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

With no annotations, the description does real work: it discloses that this is a mutation, that it has cascading side effects ('report everything else that changed'), and that it can silently fail to apply a value due to hidden prompts, unmet dependencies, or choice rules, and it names the failure mode rather than pretending success. It stops short of saying whether changes are held in memory or written to disk, which matters 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?

Two tight sentences with the core action front-loaded and the failure/alternative note appended. Dense and largely waste-free, though the parenthetical about failure causes is slightly compressed.

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?

An output schema exists, so return values need not be explained, and the description covers action, side effects, and failure reporting for a 3-param mutation tool. The main remaining gap is the unidentified 'name' parameter and the persistence semantics of the change.

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 0% (three bare string params), so the description must compensate. It richly explains the 'value' parameter's accepted forms (y/m/n for bool/tristate, number or string otherwise) but never explains 'name' (presumably a config or session identifier) or clarifies that 'symbol' is the target Kconfig symbol name.

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 ('Assign a value ... as if in menuconfig') plus the value encoding for bool/tristate vs other types, and adds the cascade-reporting behavior. It is clearly distinct from read-only siblings like kconfig_search or kconfig_diff, and it names kconfig_why_not as the diagnostic follow-up.

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 concrete when-to-use framing (mirror a menuconfig edit) and an explicit alternative for the failure path: 'use kconfig_why_not to see why' when the value doesn't stick. It does not say whether a config/session must be loaded first or when to prefer kconfig_load/save, so the guidance is clear but not exhaustive.

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