easylogger-integration

easylogger-integration is a skill for Claude Code, Codex from easyzoom/aix-skills. It costs 36 tokens per session (747 once invoked), scanned A, original, MIT.

A guide for adding and troubleshooting EasyLogger, an embedded logging library that can send messages through UART, flash, files, networks, or other outputs.

In plain words
What is it for?
Use it to configure output paths, filters, timestamps, colours, asynchronous logging, flash logging, buffer policies, and runtime log levels.
Why use it?
It helps prevent logging from losing messages, blocking the firmware, distorting timing, or producing misleading timestamps and ordering.

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

easylogger-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 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.

EasyLogger Integration

Overview

Use this skill to integrate EasyLogger without making logs distort the system being debugged. Confirm output backend, timestamp source, concurrency, buffer policy, and log level before relying on logs as evidence.

When To Use

Use this skill when:

  • The user wants to add or debug EasyLogger in MCU, RTOS, or bare-metal firmware.
  • Logs are missing, truncated, blocking, out of order, too slow, too verbose, or not timestamped correctly.
  • The task involves elog_port, UART output, flash/file logging, filters, colors, async output, or runtime log levels.

Do not use this skill when the issue is raw UART capture quality. Use embedded-serial-log-debug first.

First Questions

Ask for:

  • Target MCU/RTOS/compiler and EasyLogger version or source.
  • Output backend: UART, RTT, semihosting, file, flash, network, shell, or custom.
  • Whether logs can block, allocate memory, or run in interrupt context.
  • Timestamp source and desired format.
  • Current elog_cfg and port functions if available.
  • Symptom and sample log output.

Integration Checklist

  1. Bring up one output path. Prove a minimal blocking UART/RTT output works before enabling async, flash, or network logging.

  2. Implement port functions deliberately. Output, lock/unlock, time, and optional color handling must match the target environment.

  3. Set log levels and filters. Avoid enabling verbose logs globally on timing-sensitive firmware.

  4. Decide concurrency policy. Use mutexes or critical sections when multiple tasks or ISRs can log.

  5. Bound cost. Understand stack, heap, formatting, blocking time, and output bandwidth.

  6. Preserve diagnostic value. Logs should include module, level, time, and enough context to correlate with faults or events.

Porting Checks

  • elog_port_output cannot deadlock if called from error paths.
  • Lock implementation is safe before and after scheduler start.
  • ISR logging policy is explicit: forbidden, buffered, or minimal.
  • Timestamp source is initialized before first log or handles early boot.
  • UART backend does not block forever if host is disconnected.
  • Flash/file logging does not erase production data without approval.

easylogger-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 747 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.
