yocto-build-debug

yocto-build-debug is a skill for Codex from prashantdivate/awesome-yocto-ai-agent-skills. It costs 119 tokens per session (572 once invoked), scanned A, original, MIT.

A troubleshooting skill for Yocto Project builds. Yocto is a system for assembling custom Linux operating systems for embedded devices, and BitBake is its build tool.

In plain words
What is it for?
Use it to investigate parse, download, patch, compile, packaging, quality-check, dependency, cache, disk-space, and host-environment failures.
Why use it?
It helps narrow a failed build to the relevant stage instead of repeating a full image build or changing configuration blindly.

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

yocto-build-debug 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/yocto_log_triage.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Yocto Build Debug

Workflow

  1. Identify the build entrypoint: Makefile, kas, repo, oe-init-build-env, container script, CI job, or vendor wrapper.
  2. Confirm MACHINE, DISTRO, BBLAYERS, TMPDIR, DL_DIR, SSTATE_DIR, and target image/recipe.
  3. Reproduce the smallest failing command. Prefer parse, fetch, or one task over a full image rebuild.
  4. Inspect logs before editing metadata. Use yocto_log_triage.py with the build directory for a quick scan.
  5. Classify the failure: parse, layer, provider, fetch, patch, configure, compile, install, package, QA, image, test, or signature.
  6. Route metadata questions to $bitbake-metadata; route board boot/deploy issues to $yocto-deploy-flash or $yocto-bsp-bringup.

Guardrails

  • Do not recommend deleting tmp/ or sstate-cache/ until narrower evidence has been checked.
  • Do not silence QA with INSANE_SKIP until the package/file/license root cause is known.
  • Do not assume deploy output is under tmp/; many builds use tmp-glibc, multiconfig paths, or custom TMPDIR.
  • Do not change provider/version policy globally without checking affected recipes and images.
Files

What ships with it

4 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.

Changes

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.
