Integrate with Google's Gemini CLI for delegating tasks to Gemini. Use when you need an alternative AI perspective, Google Search grounding, parallel task execution, or want to leverage Gemini's 1M token context window. Enables "Claude calling Gemini" patterns for diverse AI collaboration.

Integrate with Claude Code CLI for delegating complex coding tasks. Use when you need to spawn a separate Claude Code instance to work on files, run tests, or perform multi-step coding operations in a specific directory. Enables "Claude calling Claude" patterns for parallel work or specialized contexts.

Use when writing, editing, or refactoring code that calls any third-party SDK, API, or library; installing or importing external packages; debugging when an API call returns success but the expected side-effect doesn't happen; hitting 4xx errors from an external API; or when something 'doesn't work' and the code involves an external service.

URDF robot description generation and default generation-time validation. Use when creating, editing, regenerating, inspecting, or debugging `.urdf` files, Python `gen_urdf()` sources, robot links, joints, limits, inertials, visual/collision geometry, mesh references, frame conventions, or generated robot-description artifacts. Use the SRDF skill for MoveIt2 semantic groups and IK/path-planning semantics; use the Replicator artifact review pane for project artifact paths; use the CAD skill for STEP/STL/3MF/DXF/GLB outputs.

Build, modify, and debug tscircuit (React/TypeScript) PCB designs. Use when working with tsci CLI (init/dev/search/add/import/build/export/snapshot/push), choosing footprints, placing parts, wiring nets/traces, or preparing fabrication outputs (Gerbers/BOM/PnP).

Use when Replicator needs off-the-shelf STEP parts for screws, bearings, motors, servos, connectors, boards, rails, or other purchasable CAD components before creating placeholder geometry.

MoveIt2 SRDF generation, validation, and planning-semantics workflow. Use when creating, editing, regenerating, inspecting, or validating `.srdf` files, `gen_srdf()` sources, MoveIt planning groups, virtual joints, passive joints, end effectors, group states, disabled collisions, URDF-linked planning semantics, or SRDF handoff for live review. Use the URDF skill for robot structure, the SDF skill for simulator descriptions, and the Replicator artifact review pane for project artifact paths.

Review DXF and STEP/STP uploads for SendCutSend.com orders using its ordering guide, catalog, and specs. Use only for SendCutSend.com preflight reports covering upload readiness, selected material/SKU/thickness/service availability, and service-specific checks for laser cutting, CNC routing, bending, tapping, countersinking, hardware insertion, and finishing.

SDFormat/SDF model and world generation, validation, and simulator handoff. Use for `.sdf` files, SDFormat XML, Python `gen_sdf()` sources, models, worlds, links, joints, poses, frames, inertials, visual/collision geometry, mesh URIs, sensors, lights, physics, plugins, includes, Gazebo, static SDF review, or simulator-specific metadata. Do not use for signed-distance-field geometry.

Write or revise hardware product requirements (product/README.md, product/requirements.json, product/contract.json). Use at the start of any hardware product design before parts selection.

Hardware product pipeline orchestrator (PRD → BOM → PCB → CAD → fabrication). Use FIRST for any request to design a hardware product, electronic device, PCB, or enclosure end-to-end. Routes to replicator-prd, replicator-parts, replicator-pcb, replicator-cad.

Design PCBs as code with tscircuit (React/TSX) and the tsci CLI - schematic, layout, DRC, Gerber/BOM/CPL export for JLCPCB fabrication. Use after the BOM stage when the product needs a custom PCB.

Select electronic components and build a procurement-ready BOM with real LCSC/JLC supplier evidence (stock, price, datasheet). Use after the PRD stage and before PCB design. Provides parts_search.py (jlcsearch API) and bom_validate.py (schema gate).

Parametric CAD modeling with build123d (Python) - enclosures, mechanical parts, assemblies. Builds a scene from cad/parts/*.py, exports STEP/GLB, renders PNG views for visual self-review, and prepares STL/3MF for printing. Use after PCB release (or directly for non-PCB products).
