Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00170 | $0.03234 |
| Opus 5 | $0.00085 | $0.01617 |
| Sonnet 5 | $0.00034 | $0.00647 |
| Haiku 4.5 | $0.00017 | $0.00323 |
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.
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.
- If the user asks about the existing RHS2116/LFP, 80channel_v2, or power-board project family, read
references/project-lessons.mdandreferences/pcb-rules.mdfirst. - If the user provides a new
.eprj2file, runscripts/extract_eprj2_summary.py <path-to-eprj2>before making design claims, then compare the result with the reference files. - If the user provides a Gerber/CAM export folder,
.DRLdrill files, orFlyingProbeTesting.json, runscripts/summarize_cam_folder.py <path-to-folder>and readreferences/cam-output.md. - 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. - If the task is parsing or validating
.eprj2internals, readreferences/eprj2-format.md. - 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:
- Power tree:
BAT,VBUS+5,VCC,VCC_SW,VCC3V3,VCC1V2,VSTM-5,V_WL, regulators/chargers/switches, return paths, and decoupling. - Analog/electrode interface: RHS2116/RHD2164 inputs,
A0throughA63, FE nets, high-impedance routing, local bypassing, quiet ground, and connector or contact-pad pinout sanity. - 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. - Stackup and copper planes: distinguish the two-layer LFP/power boards, four-layer 80channel_v2
.eprj2boards, and six-copper-layer quality-test CAM export before applying any layout heuristic. - Manufacturing output: Gerber layer set, board outline, drill tools, flying-probe pin/net coverage, paste/solder mask presence, and top/bottom assembly balance.
- 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.
- Lichuang EDA project integrity: schematic-to-PCB conversion, named nets versus generated nets, BOM flags, LCSC supplier fields, active copper layers, and footprint metadata.
What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
