Use when opening a PR and driving it to green CI — push the branch, write a high-level PR description, watch checks, fix failures, and keep looping until green; also use when an already-open PR gets new commits.
Use when the user starts, resumes, switches, saves, or recalls a named task or ongoing work across sessions (e.g. "remember this", "continue X", "what was I doing on Y", "track this task").
Git commit workflow. Load when finishing any code-change task (after verification) to commit and push, or when explicitly staging/committing.
Use when modifying or adding a transform, loss, model, method, package, task-model, config, docs page, or example in a Lightly AG repo (lightly-ssl or lightly-train) and you need repo-specific conventions.
Spawn a subagent to run a task. Use when you want to delegate work to a separate pi instance.
Use when configuring or replicating LT-DETR v2 (ltdetrv2-s/m/l/x) COCO benchmarks via the lightly-train wrapper — model alias map, global vs per-rank batch size, recipe invariants, ECDet config mapping, cluster pins, and common gotchas.

| Guideline | Reason |
|---|---|
| Use 4-6 concurrent | Sweet spot for most systems |
| Unique temp dir per run | Avoids file collisions |
| Use absolute paths | Avoids cwd confusion |
Always wait | Ensures all processes finish |
| Parenthesize each bg job | (cmd &) not { cmd & } |
⚠️ Critical: Use subshells for background jobs
Pattern (command > output.txt) & works reliably.
Pattern { command > output.txt & } does NOT work with ddgs.
⚠️ Danger: Temp file race conditions
Never use $$ or variable temp paths in filenames across parallel invocations.
