From the author

Use when a user needs to get started with CDF Auto-Labeling, plan a scenario, run or debug a shipped cookbook, author prompts or cookbooks, migrate a pipeline, configure a stage, or pull the prebuilt stage containers from NGC (nvcr.io). Confirm critical inputs (data path, output path, endpoints) and ask when any are missing. This is a router: read the matching reference instead of inventing a workflow.

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

CDF Auto-Labeling is a central routing skill designed to guide users through the lifecycle of automated data labeling tasks within the Cosmos Data Factory ecosystem. It provides a structured approach to onboarding, scenario planning, cookbook authoring, and pipeline execution. By acting as a router, it directs users to specialized documentation for specific tasks—such as migrating pipelines, debugging workflows, or managing containerized stages—while enforcing strict input validation and operational guardrails to ensure reproducible results.

What it does

  • Routes users to specific documentation based on their current task or stage in the pipeline.
  • Validates critical run inputs like data paths, output directories, and model endpoints.
  • Provides a standardized workflow for running, debugging, and customizing annotation cookbooks.
  • Facilitates the integration of new stages and the management of prebuilt container images.
  • Enforces operational guardrails to prevent common errors like hardcoding secrets or skipping validation steps.

When to use it

  • When you are a new user needing to get started with CDF Auto-Labeling.
  • When you need to plan a new annotation scenario or adapt an existing cookbook.
  • When you are troubleshooting a failed pipeline run or debugging a specific stage.
  • When you need to migrate an external annotation repository into the CDF framework.
  • When you need to pull or configure prebuilt stage containers from NGC.

Advantages

  • Ensures consistent and reproducible pipeline execution through standardized cookbooks.
  • Prevents configuration errors by mandating input validation before execution.
  • Simplifies complex workflows by breaking them down into manageable, modular tasks.
  • Promotes best practices by delegating specialized tasks to dedicated reference guides.

Usage examples

“I cloned the repo and have my own warehouse-safety video. How do I produce auto-labels for my domain?”
The agent will guide you to verify your environment, run a shipped example to confirm the stack, plan your scenario, adapt a cookbook, and execute a dry-run.
“How do I pull the prebuilt stage containers from NGC?”
The agent will direct you to the ngc-containers reference and provide instructions on using make pull to retrieve the necessary images.

CDF Auto-Labeling

Use this skill when a user wants to kick off CDF Auto-Labeling on their own data, domain, or use case, or when the request matches a shipped cookbook, stage, authoring, or migration task. This is a router: sequence the specialized references instead of duplicating their detail.

Stage references: super-resolution, detection-and-tracking, captioning, visual-qa, reasoning, person-attribute-search, grounding-2d, referring-expressions, training-export.

Instructions

  1. Confirm the critical run inputs with the user before doing anything else, and ask a concise question whenever one is missing or ambiguous - never guess or silently invent a default. At minimum confirm: input data path, output path, VLM/LLM endpoint URLs and model names, model cache path, GPU ids, and (for reasoning-capable models) the max_tokens cap. Restate the confirmed values back to the user before the first execution.

  2. Verify the environment: repository cloned, make targets available, the model cache path exists, the VLM/LLM endpoints are reachable, and a GPU is available. State any missing prerequisite as a blocker instead of assuming it. If the stage images are not present locally, offer to pull the prebuilt images from NGC with make pull instead of building them. Use ngc-containers.

  3. Run a shipped example first to confirm the stack works end to end before customizing. Pick the closest operator pipeline - video data augmentation, event-and-person-attribute-search, or event-verification-reasoning - and run its committed cookbook. Use the matching operator reference.

  4. Plan the target scenario: define modality, domain, intended consumer, and required annotations, and get a minimal stage subset. Use scenario-planning.

  5. Adapt the closest shipped cookbook to the new domain rather than authoring from scratch. Use cookbook-authoring.

  6. Author the domain prompts and question banks. Use prompt-authoring.

  7. Configure the per-stage settings for the domain (detector classes or SAM3 prompts, endpoints, windowing, max_tokens). Use the relevant stage reference, starting with detection-and-tracking.

  8. Dry-run the adapted cookbook, then execute and validate the outputs. Use workflow-runner-debugging.

Adopting an existing external annotation or dataset-generation repository into CDF instead of starting from a shipped cookbook is a migration task; use pipeline-migration for that path.

Examples

New user, new domain: "I cloned the repo and have my own warehouse-safety video. How do I produce auto-labels for my domain?"

Guided path:

  • Confirm env (model cache, VLM/LLM endpoints, GPU), then prove the stack on a shipped example before customizing:

make run SCRIPT=workflow-runner:main \
  ARGS='--cookbook-file cookbooks/video_data_augmentation/configs/pipeline_video.yaml --container-dry-run'
  • Plan the domain (scenario-planning) -> subset detection_and_tracking -> captioning -> visual_qa -> reasoning -> training_export (add grounding_2d for caption→boxes or referring_expressions for boxes→phrases; use grounding-2d / referring-expressions).

  • Copy the closest cookbook to cookbooks/warehouse_safety/configs/pipeline.yaml and adapt inputs, detector classes/SAM3 prompts, prompts, and question banks.

  • Dry-run the new cookbook, then run for real and validate outputs:

make run SCRIPT=workflow-runner:main \
  ARGS='--cookbook-file cookbooks/warehouse_safety/configs/pipeline.yaml --container-dry-run'

Guardrails

  • Do not guess or fabricate the critical inputs enumerated in step 1; if any is missing or ambiguous, ask the user and confirm before executing.

  • Do not customize a cookbook before a shipped example runs clean; a broken base makes domain debugging ambiguous.

  • Keep the first custom pipeline minimal - only the stages needed for the requested annotations - and expand later.

  • Verify that every selected stage's service package and image exist in the current branch before promising an end-to-end run.

  • Do not put secrets, tokens, or absolute home paths in committed cookbooks; use placeholders such as <model-cache> and env vars for endpoint keys.

  • For reasoning-capable models (for example Gemini 3 Flash), raise max_tokens on the visual_qa and reasoning LLM substages to avoid the thinking-token tax; keep the default cap for non-reasoning models.

  • Do not rely on non-CDF pipelines, commands, or file locations. A first run must be reproducible through workflow-runner:main inside this repo.

Files

references/stages/super-resolution.md

Super Resolution stage

Single-stage reference for the super_resolution stage (SeedVR2) that upscales low-resolution video clips (the original clip) into super-resolved active media for downstream auto-labeling stages. Video pipelines only.

When to use / not use

  • Use: picking the SeedVR2 resolver/variant, setting the resolution policy, or debugging an SR stage that fails, OOMs, or produces empty output.

  • Do not use: to run a full pipeline end to end, or to author or restructure a whole cookbook.

Config

Cookbook block super_resolution: (essential fields):

  • enabled: true

  • resolver: seedvr2

  • variant: seedvr2_3b (use seedvr2_7b only with more GPU memory)

Key stage_args.super_resolution flags:

  • --resolution-policy — pick one: auto upscales only low-res clips and passes high-res through unchanged; force upscales every clip; off disables upscaling.

  • --min-input-short-side, --min-input-long-side — thresholds that classify a clip as low-res under auto.

  • --res-h / --res-w — target output resolution.

  • --window-frames, --overlap-frames — temporal window and overlap.

  • --empty-output-policy — pick one: fail stops the run when SR yields no output; warn logs and continues.

Instructions

This skill returns configuration or debugging guidance; it does not run the pipeline. Provide the config immediately - do not gate it behind execution. The three numbered steps are the only flow nodes; Config, Examples, Gotchas, and Guardrails are reference content and author-time constraints, not flow steps or loops. The config is returned once.

  1. Classify the task. Configuring/tuning super_resolution, or debugging a stage that fails, OOMs, or empties - both in scope. For a mixed request that asks for super_resolution config AND a full-pipeline run or whole-cookbook authoring, answer the super_resolution portion here and hand off only the run/whole-cookbook portion to the operator or cookbook-authoring skill. STOP and hand off entirely only when the request has no super_resolution config/debug part.

  2. Gather needs. For a config/tuning request the needed inputs are the resolver/variant, resolution policy, target resolution, and window/overlap; return the config from these without requiring execution-environment details. Ask for runtime details (GPU, model cache, input media) only when they are relevant to the requested tuning or to a debug diagnosis (e.g. OOM, empty output) - not for a plain config response. If an input that is actually required for the request is missing or ambiguous, ask once in a single consolidated question; if it stays unresolved after that clarification, state the assumption you would need or STOP and report the blocker - do not re-ask indefinitely.

  3. Return the config or fix. Produce the super_resolution: block and stage_args per Config (or the debug remedy). Suggest a dry-run (--container-dry-run) so the caller can verify the generated command before running.

Execution is out of scope. This skill only produces configuration; it does not run the stage. Executing (Docker via workflow-runner, which requires explicit user approval) is the operator skill's responsibility.

When debugging. On GPU OOM, missing model cache, missing input media, or empty SR output (with --empty-output-policy fail), report the specific cause from the failing output and the fix, then stop; do not fabricate media or silently retry.

Examples

Upscale only low-res clips (SeedVR2 3B), pass high-res through unchanged:

super_resolution:
  enabled: true
  resolver: seedvr2
  variant: seedvr2_3b
stage_args:
  super_resolution: >-
    --resolution-policy auto
    --min-input-short-side 720 --min-input-long-side 1280
    --res-h 1080 --res-w 1920
    --window-frames 24 --overlap-frames 4
    --empty-output-policy fail

Dry-run to inspect the generated Docker command before running:

make run SCRIPT=workflow-runner:main \
  ARGS='--cookbook-file cookbooks/video_data_augmentation/configs/pipeline_video.yaml --container-dry-run'

Gotchas

  • Heavy GPU stage (SeedVR2) — plan a dedicated GPU; seedvr2_7b needs more memory than seedvr2_3b.

  • Docker is required to run this stage.

Guardrails

Follow guardrails.md. SeedVR checkpoints mount via <model-cache>; this stage requires Docker to run.
