Skills (16)

• mbg-agent-interface

  How any AI agent drives MBG through its tool surface — the `scripts/mbg` command line or the same tools over MCP (`scripts/mbg mcp`) — discovering what is legal, checking and simulating a netlist, generating and inspecting a layout, steering placement with a hints file, verifying, and reading the on

• mbg-ai-experiment-audit

  Audits an MBG AI-assisted analog-design experiment record for reproducibility, prompt independence, bounded LLM refinement, artifact completeness, AI metrics, and evidence-based results. Use this skill when reviewing experiment.json, generated SPICE, GDS, simulation outputs, or DRC/LVS/PEX reports f

• mbg-context-economy

  How to work in this repository without burning the context window - resolve the repo from $MBG_ROOT instead of searching $HOME, read a file once at the right granularity, never poll git state, and climb the verification ladder cheapest-first instead of re-running the whole flow. Use at the start of

• mbg-design-regression

  Reads AI-Generated-Design-Result as both working design output and regression evidence, understands the "<design>_designcontext_v2/" convention for new pipeline runs kept beside preserved baselines, and inventories the artifacts (.gds, .lvs.out, .magic.drc.rpt, .spice, REPORT.md) each design directo

• mbg-extension-authoring

  Creates or reviews canonical agent skills and workflows under .ai/, plus OpenCode-only custom tools under .opencode/tools, for the Microelectronic Block Generator repository. Use this for authoring or reviewing SKILL.md files, .ai/workflows entries, or .opencode/tools/*.ts files. Do not use it for a

• mbg-full-auto

  Fully automated analog design from one request — the /mbg-full-auto command. Parses the specification, runs pre-layout optimization, layout, DRC, LVS, PEX extraction, PEX simulation and PEX-aware fine-tuning, with Devil and Angel reviewers at every stage, then a tapeout-ready sign-off gate and an au

• mbg-ic-verify

  Runs DRC, LVS, and PEX physical verification for GDSII layouts using Magic and netgen, with automatic port-order fixing for LVS. Use when the user asks to "run DRC", "check LVS", "extract parasitics", "verify layout", "run pex", or otherwise wants post-layout verification of an existing GDS under GF

• mbg-pex-aware-flow

  Drives the MBG two-loop design methodology — pre-layout optimization, then PEX-aware post-layout optimization. Use whenever a design has performance targets (gain, bandwidth, phase margin, offset, delay, power) and must be taken from specification to a sign-off candidate. Use it to decide what to do

• mbg-placement-debug

  Inspects analog device placement — matching groups, symmetry constraints, device bounding boxes and overlap, pin access points, reserved zones, routing channels, congestion, and the placement-routability feedback loop. Use when a layout's device placement looks wrong, a net cannot find a routable pa

• mbg-repo-analysis

  Maps the Microelectronic Block Generator repository, traces the active execution path from a design script to the layout pipeline, separates active implementations from legacy code kept only for backward compatibility, and analyzes SPICE netlists (devices, nets, terminals, connectivity). Use before

• mbg-reviewers

  The Devil and Angel critic sub-agents and how their reviews are synthesized into a decision. Use when acting as a reviewer for a design stage, when interpreting review findings, or when deciding whether a design may proceed or be signed off. Do not use it to modify a design directly — reviewers advi

• mbg-routing-debug

  Traces nets, inspects vias and metal-layer usage, and detects shorts, opens, and route conflicts using the DesignContext grid router and internal connectivity checker. Use when a route failed, a net looks shorted or open, or you need to verify physical connectivity against the SPICE netlist before e

• mbg-setup

  Sets up this repository on a new machine — the Python environment, the GF180MCU PDK, the EDA tools (Magic, netgen, KLayout), the shell integration in $HOME/.mbg, and the OpenCode / Claude Code / Codex agent integrations, repo-scoped or for the whole user account — then verifies the result. Use when

• mbg-spice-sim

  Runs ngspice simulations for analog blocks in this repository and turns the raw output into readable data, using mbg.simulation (run_spice, raw_to_csv, parse_dat). Use when the user asks to simulate a netlist, measure gain, bandwidth, delay or offset, sweep corners, or compare pre-layout against pos

• mbg-spice-to-gds

  Converts a SPICE subcircuit netlist into a DRC-clean GDSII layout using gLayout, via the single entry point spice_to_gds_with_checks(netlist). Use when the user asks to generate GDS from SPICE, convert a netlist to layout, "layout my circuit", or "spice to gds" for the GF180MCU 3.3V PDK. Do not use

• mbg-voltage-reference

  Designs, characterises and lays out a voltage reference (bandgap with vertical PNPs and poly resistors, or MOS-only zero-TC) on gf180mcuD with the MBG tools — topology choice, first-cut sizing equations, the `mbg measure vref` recipe across temperature, supply, corners and IBIAS, and layout matching
