jlcpcb-headstage-pcb

jlcpcb-headstage-pcb is a skill for Codex from Dissipative-ATLAS/jlceda-codex-mcp. It costs 170 tokens per session (3,234 once invoked), scanned A, original, MIT.

A project-specific guide for reviewing and improving printed-circuit-board designs made for JLCPCB's electronics-manufacturing service. It also covers manufacturing files such as Gerbers and drill files.

In plain words
What is it for?
Use it to review power design, parts, connectors, footprints, bills of materials, assembly risks, and exported fabrication files.
Why use it?
It gives developers a repeatable way to inspect board projects and manufacturing exports, while separating project lessons from official factory rules.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

jlcpcb-headstage-pcb scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/extract_eprj2_summary.py, scripts/summarize_cam_folder.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

JLCPCB Headstage PCB

Core Workflow

Use this skill as a project-specific review guide, not as an official JLCPCB fabrication rulebook.

  1. If the user asks about the existing RHS2116/LFP, 80channel_v2, or power-board project family, read references/project-lessons.md and references/pcb-rules.md first.
  2. If the user provides a new .eprj2 file, run scripts/extract_eprj2_summary.py <path-to-eprj2> before making design claims, then compare the result with the reference files.
  3. If the user provides a Gerber/CAM export folder, .DRL drill files, or FlyingProbeTesting.json, run scripts/summarize_cam_folder.py <path-to-folder> and read references/cam-output.md.
  4. If the task is BOM, component choice, JLCPCB/LCSC metadata, SMT assembly, connector choice, BGA/FPC/BTB risk, or footprint risk, read references/part-library.md.
  5. If the task is parsing or validating .eprj2 internals, read references/eprj2-format.md.
  6. If the user asks for current official JLCPCB manufacturing, DFM, or SMT rules, verify against official current sources before treating any number as a manufacturing limit.

Review Priorities

Start reviews in this order:

  1. Power tree: BAT, VBUS+5, VCC, VCC_SW, VCC3V3, VCC1V2, VSTM-5, V_WL, regulators/chargers/switches, return paths, and decoupling.
  2. Analog/electrode interface: RHS2116/RHD2164 inputs, A0 through A63, FE nets, high-impedance routing, local bypassing, quiet ground, and connector or contact-pad pinout sanity.
  3. Digital interfaces: USB_D+, USB_D-, MISO1, MOSI1, SCK1, CS1, MISO2, MOSI2, SCK2, CS2, FPGA flash nets, line length, layer changes, and nearby ground return.
  4. Stackup and copper planes: distinguish the two-layer LFP/power boards, four-layer 80channel_v2 .eprj2 boards, and six-copper-layer quality-test CAM export before applying any layout heuristic.
  5. Manufacturing output: Gerber layer set, board outline, drill tools, flying-probe pin/net coverage, paste/solder mask presence, and top/bottom assembly balance.
  6. Compact-board manufacturability: 0201/0402 density, BGA escape, FPC/BTB connector pitch, via size, solder-mask expansion, silkscreen clearance, test pads, contact pads, and extended-part dependency.
  7. Lichuang EDA project integrity: schematic-to-PCB conversion, named nets versus generated nets, BOM flags, LCSC supplier fields, active copper layers, and footprint metadata.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

jlcpcb-headstage-pcb is a skill published in the GitHub repository Dissipative-ATLAS/jlceda-codex-mcp (4 stars, last pushed 2mo ago), licensed MIT. It adds 170 tokens to every session and 3,234 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
