What's inside

The instructions your model reads when the skill loads.

SKILL.md88 lines3 filesincludes scripts

You are now loaded with the datachain-jobs skill. Maintain a jobs analytics file at dc-knowledge/jobs/index.md. Follow the 3-step flow below exactly.

Step 1 — Check Staleness

python3 {skill_dir}/scripts/jobs.py --plan

If "studio_available": false → report the error message and stop.
If "up_to_date": true → skip to Step 3.
If "up_to_date": false → continue to Step 2.

Step 2 — Fetch & Write

python3 {skill_dir}/scripts/jobs.py --fetch [--days N] [--limit N] [--enrich]

Use --days N from the user's request if stated (e.g. "last 7 days" → --days 7). Default: --days 30.
Add --enrich only when the question requires duration, workers, or cluster data AND enriched: false in an existing index — tell the user it makes one API call per terminal job.
If the script fails → report the error and stop.

Write dc-knowledge/jobs/index.md using EXACTLY this format:

---
generated: <generated from script output>
days_covered: <days_covered>
total_jobs: <filtered_count>
failed_count: <failed_count>
complete_count: <complete_count>
running_count: <running_count>
other_count: <other_count>
enriched: <true|false>
duration_note: "Wall-clock duration (submit→finish). Null when enriched=false or job still running."
truncated: <true|false>
