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 | $0.00100 | $0.00693 |
| Opus 5.5 | $0.00040 | $0.00277 |
| Sonnet 5.5 | $0.00020 | $0.00139 |
| Haiku 4.5 | $0.00010 | $0.00069 |
Grade A, and why
bitbake-metadata 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.
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.
How it starts
The opening of the file, as written. The whole thing — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
BitBake Metadata
Core Workflow
- Determine the release and BitBake version from the workspace before applying syntax guidance. Check
bitbake --version, branch names,LAYERSERIES_COMPAT, and the docs selected by the parent Yocto release. - Inspect existing metadata first. Search for the recipe, provider, class, variable, override, task, and package name across all configured layers.
- Read official docs for the exact mechanism. Use bitbake_doc_router.py with a topic name to choose a starting URL.
- Explain metadata changes in terms of parse-time effects, task effects, package effects, and signature/sstate effects.
- Validate with BitBake introspection rather than assumptions.
Introspection Commands
Use the project wrapper if one exists. Otherwise, after sourcing the build environment:
bitbake-layers show-layers
bitbake-layers show-recipes RECIPE
bitbake-layers show-appends
bitbake -e RECIPE | less
bitbake -c listtasks RECIPE
bitbake -g RECIPE
bitbake-dumpsig SIGDATA_OR_SIGINFO
bitbake-diffsigs SIGDATA_A SIGDATA_B
For targeted variable checks, prefer bitbake -e RECIPE and search for the final assignment plus history comments.
Metadata Editing Rules
- Preserve local style for variable operators, override order, indentation, and layer layout.
- Prefer
:append,:prepend, and:removeoverride syntax for modern releases, but verify old-release syntax before changing legacy branches. - Keep machine, distro, image, and recipe concerns in their correct files.
- Use
.bbappendwhen changing recipes from another layer. - Keep checksums, licenses, and
SRC_URIchanges explicit and reviewable. - Do not set
PREFERRED_PROVIDER,PREFERRED_VERSION,BBMASK, or global variables without checking blast radius.
References
Read only the reference file needed for the task:
- official-sources.md: authoritative BitBake docs and source links.
- metadata-cheatsheet.md: syntax, operators, overrides, tasks, and fetcher reminders.
- debugging.md: parse, fetch, task, dependency, QA, signature, and sstate debugging workflow.
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.

bitbake-metadata is a skill published in the GitHub repository prashantdivate/awesome-yocto-ai-agent-skills (4 stars, last pushed 4mo ago), licensed MIT. It adds 100 tokens to every session and 693 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-08-31.
