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 | $0.00036 | $0.00572 |
| Opus 5 | $0.00018 | $0.00286 |
| Sonnet 5 | $0.00007 | $0.00114 |
| Haiku 4.5 | $0.00004 | $0.00057 |
Grade A, and why
nr-micro-shell-integration 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.

nr_micro_shell Integration
Overview
Use this skill to integrate nr_micro_shell as a compact command console. Keep the first port minimal: verified character I/O, one read-only command, bounded buffers, and explicit handling for destructive commands.
When To Use
Use this skill when:
- The user wants a tiny shell/CLI on an MCU and mentions nr_micro_shell.
- Commands are not recognized, input is garbled, completion/history fails, or shell processing blocks firmware.
- The target needs a lower-footprint alternative to larger embedded shells.
Do not use this skill when raw UART is not proven. Use embedded-serial-log-debug first.
First Questions
Ask for:
- Target MCU/RTOS/compiler and nr_micro_shell version/source.
- Transport: UART, USB CDC, RTT, TCP, or custom stream.
- Polling, interrupt, DMA, or task-based input model.
- Command table/registration approach.
- Maximum command length, argument count, and stack/RAM budget.
- Whether shell is enabled in production builds.
Integration Checklist
-
Verify raw I/O. Confirm single-character RX/TX before attaching shell parsing.
-
Configure buffers. Set command line, history, and output buffers within RAM limits.
-
Register one safe command. Start with
help,version, orstatus. -
Validate argument parsing. Commands must reject missing, too many, or invalid arguments.
-
Bound output. Avoid long blocking output that starves watchdogs or RTOS tasks.
-
Guard risky commands. Reset, erase, format, calibration, flash writes, or network writes need build guards or authentication.
Common Failures
- RX callback stores characters but shell process function is never called.
- Command table is not linked or is optimized out.
- Backspace/newline behavior mismatches terminal settings.
- Long command output blocks system timing.
- Debug shell remains enabled in production without restrictions.
Verification
Before claiming nr_micro_shell works:
- State transport, scheduling model, buffer sizes, and command registration method.
- Confirm raw RX/TX,
help, one custom read-only command, invalid command, and argument error behavior. - Confirm risky commands are absent, disabled, or guarded.
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.

nr-micro-shell-integration is a skill published in the GitHub repository easyzoom/aix-skills (31 stars, last pushed 1mo ago), licensed MIT. It adds 36 tokens to every session and 572 once invoked, about $0.0002 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.
