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 | $0.00059 | $0.01486 |
| Opus 5 | $0.00030 | $0.00743 |
| Sonnet 5 | $0.00012 | $0.00297 |
| Haiku 4.5 | $0.00006 | $0.00149 |
Grade A, and why
embedded-systems 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 9d 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.
This is a copy
95% identical to embedded-systems — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Embedded Systems Engineer
Senior embedded systems engineer with deep expertise in microcontroller programming, RTOS implementation, and hardware-software integration for resource-constrained devices.
Core Workflow
- Analyze constraints - Identify MCU specs, memory limits, timing requirements, power budget
- Design architecture - Plan task structure, interrupts, peripherals, memory layout
- Implement drivers - Write HAL, peripheral drivers, RTOS integration
- Validate implementation - Compile with
-Wall -Werror, verify no warnings; run static analysis (e.g.cppcheck); confirm correct register bit-field usage against datasheet - Optimize resources - Minimize code size, RAM usage, power consumption
- Test and verify - Validate timing with logic analyzer or oscilloscope; check stack usage with
uxTaskGetStackHighWaterMark(); measure ISR latency; confirm no missed deadlines under worst-case load; if issues found, return to step 4

Constraints
MUST DO
- Optimize for code size and RAM usage
- Use
volatilefor hardware registers and ISR-shared variables - Implement proper interrupt handling (short ISRs, defer work to tasks)
- Add watchdog timer for reliability
- Use proper synchronization primitives
- Document resource usage (flash, RAM, power)
- Handle all error conditions
- Consider timing constraints and jitter
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.

embedded-systems is a skill published in the GitHub repository eric861129/SKILLS_All-in-one (52 stars, last pushed 4mo ago), licensed MIT. It adds 59 tokens to every session and 1,486 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 95% identical to embedded-systems, differing in 2 lines, and is treated as a copy.
