	Description		Read-only	Idempotent	Open world
`add_copper`Lay exact copper by hand where the routers leave a gap: tracks as polylines on one copper layer, and through vias. width_mm, diameter_mm and drill_mm default to the board's current track and via sizes. Nets must exist on the board. Nothing is checked here: run_drc afterwards, and ripup_routing takes copper back out.

`add_custom_footprint`Give the design a footprint of your own: a KiCad .kicad_mod (the file's text) for a package KiCad's libraries lack. It joins the design's "custom" footprint library and is used as "custom:<name>": pass that to create_custom_symbol (footprint=) or name it in the SKiDL script's footprint=; the board builder loads it like a library footprint and the KiCad project download carries it. The pads must be numbered like the pins. The CLI: `koppar footprint <design> part.kicad_mod`.

`add_project_files`Unpack a ZIP into the project folder, keeping its paths: new footprints into a .pretty library the fp-lib-table names, 3D models, a library table. Existing files are kept unless overwrite is true; the reply lists written, replaced and kept files. Base64, up to about 18 MB zipped.

`anneal_place`Dense placement by simulated annealing: wirelength inside the real outline (Edge.Cuts with its corners, notches and cutouts; a separate piece no held part stands on is left out) with courtyard gaps, edge connectors held on their edge, fixed and locked parts held, and, unless refs is given, the mounting holes, connectors and switches already on the board held too (held_mechanical). Kept clear: keepout rectangles (routing corridors) and the board's and held footprints' rule areas that forbid pads or footprints, on their own faces. A per-pad price for the bottom side (flip_cost, mm of wirelength; each bottom-side pad whose net has top-side pins costs a via). Starts from the current positions unless from_scratch. The result is legalised: no part on another, in a keep-out or off the board; a part with no legal spot that started off the board stays there (unplaced), and a result worse than the board had is not saved (the op fails, the board unchanged). Iterations scale with the parts moved within a 150 s budget: leave iterations unset.

`auto_place`Pack footprints inside the board outline with Koppar's heuristic placer (ratsnest-driven, courtyard-legal). By default every unlocked footprint moves and locked ones stay; refs names exactly which move (all others stay). Constraints: fixed (exact origin positions and rotation, never moved; locked footprints likewise), side, keepouts (rectangles), groups, near (ref within maxMm of an anchor), edge (ref to "left\|right\|top\|bottom", optionally "@mm" along that edge from the outline's top-left corner). Nothing is left past the outline except a USB/barrel/jack opening's 1.2 mm lip; placement_notes lists every part that could not be placed where asked. Coarse by design: refine the result with place_footprints.	Pack footprints inside the board outline with Koppar's heuristic placer (ratsnest-driven, courtyard-legal).

`bridge_islands`A filled pour cut into islands by routing: one through-via per island that KiCad finds cut off from its net, placed well inside the island and inside the net's main copper on another layer, clear of every other net between. Reports the islands it found no site for. Run run_drc afterwards.

`check_net_rules`Check the copper against the project's net classes and differential pairs, which KiCad's DRC does not: every class or pair net's narrowest track and the length below its class width, and every pair (X_P/X_N, X+/X-, CAN X_H/X_L) with its coupled share at the class's diff_pair_gap, both lengths and the skew.

Routing applies the same rules.	No	No	Not declared	No
`check_physics`Judge the copper by physics, which KiCad's DRC does not: impedance from the stackup on controlled nets, IR drop and heating on rails with a stated current, pair and lane skew, a ground via beside every high-speed layer change, 3W spacing between high-speed runs, and the via path under exposed paddles. Each check runs only when the board states something it can judge. With repair, the fixable findings are fixed in place (track width, skew meanders, return vias, widened rails), each kept only if KiCad counts nothing worse. finish_board runs the same repairs.

`cleanup_board`Sweep the routing: zero-length and duplicate tracks, stub tracks (a free end, and everything the track touches stays joined without it), and vias that meet their net on fewer than two layers. Contact is copper overlap, as KiCad judges it. Refills the zones first so pours count as connections. Locked items stay. The board is put back if the unconnected count or the DRC errors rise. A track running on past its last junction is cut back to it (trim_overhangs). list_removed names every item that went.

`consolidate_bom_basic`Move every resistor, capacitor and inductor bought outside JLCPCB's basic library onto an in-stock basic-library part of the same value, package and (capacitors) at least the same voltage rating. Each part outside that library adds a loading fee to a JLCPCB order, usually more than the part. Each swap becomes the line's choice (choose_bom_part with null undoes it); lines with no readable value, no SMD size or no basic part are reported and left alone.

`couple_pairs`After route_board: re-route the weakly coupled differential pairs one at a time, least coupled first. Both legs are ripped and routed alone around everything else as a pair; the new copper stays only when the pair's coupled share rises by min_gain_pct, its skew stays within max_skew_mm, KiCad counts no new open item or DRC error, and the board gains at most max_extra_vias vias. Pairs routed with the whole board lose their lanes; alone they couple. Run check_net_rules before and after.

`create_custom_symbol`Register a connectable schematic symbol for a part that is NOT in KiCad's libraries (search_kicad_symbol returned nothing). Use this for specialty ICs — LED-matrix drivers, niche sensors, etc. — INSTEAD of telling the synthesizer to model the part with discrete passives (which leaves every pin dangling and breaks the board). Provide the full datasheet pinout. The part then becomes available to the synthesizer as Part('custom', '<name>') with the exact pin names you supply here, and is added to the Verified parts table. A part with three or more pins needs footprint= naming a real, in-library footprint for its package (search_kicad_footprint with the family and pin count, e.g. 'LGA-14'); the call is rejected without one, since a generated grid of pads cannot be assembled. List every pad of the footprint, NC pins included. When the package is not in KiCad's libraries, bring your own footprint instead: footprint_mod takes the whole .kicad_mod file as text (KiCad 6+, up to 1 MB; the CLI reads it with `koppar custom-symbol --footprint-file`). It is checked as a KiCad footprint, every pad must have a pin with that pad's number (and every pin a pad), and it is stored as 'custom:<name>': the symbol uses it, and it goes on the board, into project.zip and into the fp-lib-table. footprint is then not needed. The name is used for file names: letters, digits and _ . + - (anything else becomes _). The symbol belongs to design_id.

A pad with no free corridor and no via site is CRAMPED — no router can reach it; the advice names the parts to move. Otherwise the advice says which nets to rip and route first.

`get_kicad_symbol`Return the full pin list (number, name, electrical type) and description for a specific KiCad symbol. For some high-risk power parts it also returns curated topology_constraints from datasheet-style application notes and footprint_suggestions. Use this before writing pin connections (e.g. mcu['VCC'] += vcc) so names, constraints and footprints match the symbol exactly. For a part found in KiCad, the result is ALSO enriched with that part's topology + required external parts from a datasheet database (merged into topology_constraints).

That is not a symbol: register the part with create_custom_symbol, whose pinout is checked against the datasheet. Pass design_id so the lookup is recorded for the design's dossier and a registered part belongs to it. Give library and name, or up to 12 of them in parts.

`set_design_rules`Set the project design rules (.kicad_pro) and copper layer count. Works on a board workspace and on a generated design (create_design → start_board). On a generated design the rules go into circuit.kicad_pro/.kicad_dru in place (the previous ones are snapshotted under rules_revisions/), are kept by every later project write (project.zip, a new board run), the copper is not changed and KiCad DRC judges the board against them at once: the reply carries the DRC counts and whether the Gerbers are released; the next start_board routes to the default_* values. copper_layers, stackup and board_thickness_mm are workspace-only (a generated design changes them with a new board). preset "jlcpcb" applies JLCPCB's published minimums for the layer count and writes their per-feature limits (plated rings, pad hole spacing, hole-to-track) as KiCad custom rules (.kicad_dru) that run_drc checks; explicit values override the minimums.
