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 | $0.00100 | $0.00530 |
| Opus 5 | $0.00050 | $0.00265 |
| Sonnet 5 | $0.00020 | $0.00106 |
| Haiku 4.5 | $0.00010 | $0.00053 |
Grade A, and why
hardware 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 2d 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.
What it actually says
Hardware — parts, circuits, firmware, bring-up, traps
Rule content lives in the five files below; this SKILL.md only routes
(doctrine/04-maintenance.md governs edits to this bundle too).
Route by moment
| You are about to… | Read (in this folder) |
|---|---|
| Pick an MCU, module, sensor, or any component; judge a BOM or parts proposal | parts.md |
| Design or review a circuit: power, protection, interfaces, layout concerns | circuits.md |
| Write or review embedded firmware (loops, ISRs, watchdogs, OTA, flash) | firmware.md |
| Debug a physical board, plan first power-up, or validate before shipping | bringup.md |
| Estimate battery life or a power budget ("how long on a 2000mAh cell?") | circuits.md §1 + traps.md A5 — peak budgeting, measured charge per duty cycle |
| Review a hardware project's health; name why a design or process feels fragile | traps.md |
A new design usually runs parts.md → circuits.md (power tree first) → firmware.md,
with bringup.md §1 consulted BEFORE layout — bring-up is designed, not improvised.
Scope and neighbors
Physical-world engineering judgment. Firmware architecture inherits backend/logic.md
(this bundle adds the physics); debugging inherits methods/investigate.md (this bundle
adds instruments and the four failure domains); whether to delegate → doctrine.
The stance
The physical world is analog, undocumented, and expensive to iterate: derate, measure,
and design for bring-up — and treat every datasheet as a contract whose real terms are
in the footnotes (parts.md §4). One honest limit governs all debugging here: the model
cannot see the board, so measurements come before theories (bringup.md §4).
What ships with it
5 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.

hardware is a skill published in the GitHub repository telagod/code-abyss (240 stars, last pushed 1mo ago), licensed MIT. It adds 100 tokens to every session and 530 once invoked, about $0.0005 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 2026-08-30.
