Expand workflow HDF5 demonstrations with action jitter, optionally scoped to node segments. Use for synthetic variants; do not use to collect data, alter state directly, or generate new images.

What this skill does
Mimic Workflow Demonstrations Purpose Clone successful source episodes and perturb recorded actions. Instructions 1. Run the checkout resolver and select the source HDF5. 2. Inspect successful episodes and segments. 3. Run mimic to generate the requested additional action-jitter variants. 4. Compare exact counts and preserved contracts. Resolve and inspect Treat the resolver above as part of the skill contract: a hosted copy may run outside the base repository, so never assume the current checkout contains workflows/i4hworkflows. I4HWORKFLOWSREPOURL selects the clone source. When I4HWORKFLOWS is unset, derive the fallback directory from that URL; set I4HWORKFLOWS only to reuse or choose a specific destination. Never replace an existing checkout. Use the explicit/current-chain recording. Require at least one successful source episode. If the user asks for node-scoped jitter, require that node in segment metadata. Expand --episodes is the number of generated variants, not the final total. Add --node <node-id> only when requested. Preserve the default deterministic seed unless the user supplies another. Verify and compose Confirm source count, generated count, dimensions, success flags, and segment preservation. Reject zero generated episodes. If the same prompt requests visualization, continue with i4h-workflow-dataset-convert, then i4h-lerobot-viz; raw HDF5 is not a LeRobot visualizer input. Troubleshooting On failure, inspect the first episode shape or segment error. If a requested node is absent, report available node ids. Prerequisites Require a readable HDF5 file with at least one successful episode and valid segments for node-scoped jitter. Limitations The current tool does not independently add state noise, rerun physics, or synthesize camera frames. Examples Mimic 3 more episodes and visualize my dataset. → generate three variants, convert the expanded HDF5, then launch LeRobot visualization. …
