3. [Prose and bilingual checklist](references/prose-and-bilingual-checklist.md) carries the applicable eunomia.dev prose discipline into this repository.
Use existing tutorials as living examples, not as a fixed template. Always read the `47-cuda-events` and `49-hid` English/Chinese pairs, then let the agent select one to three additional completed tutorial pairs whose subsystem, attachment type, tool shape, or target reader matches the new lesson. Read every selected file in full and record why it was chosen. Never infer house style from headings alone.
Use existing tutorials as living examples, not as a fixed template. Always read the `47-cuda-events` and `49-hid` English/Chinese pairs. The agent may select up to three additional completed tutorial pairs when their subsystem, attachment type, tool shape, or target reader adds a useful pattern. Read every selected file in full and record why it was chosen. Never infer house style from headings alone.
Treat verified implementation facts, real runtime evidence, and the user's current requirements as authoritative. Never change code, commands, output, versions, claims, qualifiers, failure behavior, or limitations to make prose smoother. When an older precedent conflicts with verified facts or the current rulebooks, preserve the facts and use only the precedent's useful teaching style.
## Apply the final gate
Reject a draft until it satisfies every non-diagnostic rule in the three references. Report each failure with the file, heading, smallest useful excerpt, reason, and a targeted correction. Never rewrite a whole section during review when a paragraph-level fix is enough.
Treat every unmarked rule in the three references as blocking unless the rule explicitly calls itself diagnostic or advisory. A **Must fix** label highlights a common hard failure; it is not the only kind of blocking rule. Report each failure with the file, heading, smallest useful excerpt, reason, and a targeted correction. Never rewrite a whole section during review when a paragraph-level fix is enough.
Paragraph length ranges are diagnostics, not quotas. A rule marked **Must fix** blocks acceptance. Preserve English and Chinese macro structure, facts, code, commands, output, examples, limitations, and references, but compose each language naturally rather than translating line by line.

- Introduce each complete file with its role in the kernel/user-space flow. After the file, select only the parts that need deeper explanation.
- Explain what advanced developers need to know: program type, attach point, context restrictions, helper or kfunc semantics, map ownership, state lifetime, concurrency, verifier constraints, event/control path, error handling, and cleanup.
- Keep build and run commands copyable. Explain prerequisites before the command and interpret real output after it.

After the rewrite, compare each README with its entry version from the end backwards. Mark every removed paragraph as moved, rephrased with all facts intact, or intentionally excluded for a reason already authorized by the task. Restore any unaccounted technical content.
Run `$bpf-tutorial-writing-style/scripts/sync-source-blocks.py --check` to verify that every complete-source block matches its repository file exactly. Then run the repository documentation generators, link checks, tests, and external review workflow.
Use the exact marker form documented in `$bpf-tutorial-writing-style/SKILL.md`; never hand-edit the generated content between the markers. From the repository root, synchronize the English and Chinese pair together after drafting. Repeat `--expected-source` once for every core source named in the task inventory:
```bash
python3 .agents/skills/write-bpf-production-tutorial/scripts/sync-source-blocks.py \
--repo "$(git rev-parse --show-toplevel)" \
--readme src/<lesson>/README.md \
--readme src/<lesson>/README.zh.md \

--expected-source src/<lesson>/<tool>.bpf.c \
--expected-source src/<lesson>/<tool>.c \
--write
```
Before acceptance, rerun the same command with `--check` in place of `--write`. Then run the repository documentation generators, link checks, tests, and external review workflow.
