manage_components

Add, list, update, or remove KiCad schematic components, and retrieve pin data by reference designator.

Instructions

Manage components (add, list, get_pins, update, remove).

Args: action: Operation ("add", "list", "get_pins", "update", "remove") lib_id: Library ID (required for "add") value: Component value (required for "add") reference: Reference designator (optional for "add", required for others) position: Position tuple (for "add"/"update") rotation: Rotation in degrees (for "add"/"update") footprint: Footprint string (for "add"/"update") ctx: MCP context (optional)

Returns: Dictionary with component data or error

B3.3/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden. It labels itself as a dispatcher but never discloses that 'remove' is destructive, whether changes are persisted or need a save call, what permissions are required, or what happens on invalid actions. For a multi-action tool containing a delete operation, this is a significant gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the action list, then a compact Args block, then a one-line Returns. The per-parameter lines are short and earn their place given 0% schema coverage; the only mild waste is the redundant restating of 'action' after it was already enumerated.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so the brief Returns line is sufficient and no return-format detail is owed. Given 7 parameters at 0% schema coverage and no annotations, the description does a fair job on argument applicability but is incomplete on the destructive nature of 'remove', error behavior, and persistence, which an agent needs before choosing this tool over the single-action siblings.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description is the only source of parameter meaning, and it delivers: it names each parameter, gives its semantic role, and states which action requires it. It still omits type-level detail (e.g. that position is a 2-number pair, that action is an unconstrained string with five valid values), but it substantially compensates for the empty schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource and enumerates the five supported actions (add, list, get_pins, update, remove), so the agent knows exactly what the tool covers. However, it gives no differentiation from the many siblings that perform the same single actions (add_component, list_components, update_component, remove_component, get_component_pins), leaving the agent to guess which entry point to prefer.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The per-parameter annotations of which arguments are required or optional per action implicitly document how each action is invoked (e.g. lib_id/value required for 'add', reference required for others). There is no explicit when-to-use guidance and no mention of the single-action alternatives that exist as siblings, so the guidance is only implied.

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