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.
Routing (Read First)
| Request looks like | Read |
|---|---|
| New user, clean checkout, first validated run, "how do I get started" | This file, then the matching reference below |
| Choose annotation targets / stage subset for a domain | references/scenario-planning.md |
| Create, review, or adapt a cookbook | references/cookbook-authoring.md |
| Write or adapt VLM/LLM prompts or question banks | references/prompt-authoring.md |
| Migrate an existing annotation repo into this one | references/pipeline-migration.md |
| Run the video data augmentation cookbook | references/video-data-augmentation.md |
| Run or choose an EPAS / PAS cookbook | references/event-and-person-attribute-search.md |
| Run event-verification reasoning | references/event-verification-reasoning.md |
| Debug an already-integrated workflow | references/workflow-runner-debugging.md |
Pull prebuilt stage images from NGC, log in to nvcr.io, or fix a missing cdf-* image | references/ngc-containers.md |
| Implement or review a new stage or Dockerized service | references/workflow-stage-integration.md |
| Configure or debug one production stage | The matching file under references/stages/ |
Stage references: super-resolution, detection-and-tracking, captioning, visual-qa, reasoning, person-attribute-search, grounding-2d, referring-expressions, training-export.
Instructions
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_tokenscap. Restate the confirmed values back to the user before the first execution.Verify the environment: repository cloned,
maketargets 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 withmake pullinstead of building them. Use ngc-containers.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.
Plan the target scenario: define modality, domain, intended consumer, and required annotations, and get a minimal stage subset. Use scenario-planning.
Adapt the closest shipped cookbook to the new domain rather than authoring from scratch. Use cookbook-authoring.
Author the domain prompts and question banks. Use prompt-authoring.
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.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(addgrounding_2dfor caption→boxes orreferring_expressionsfor boxes→phrases; use grounding-2d / referring-expressions).Copy the closest cookbook to
cookbooks/warehouse_safety/configs/pipeline.yamland 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_tokenson thevisual_qaandreasoningLLM 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:maininside this repo.

Migration Playbook
Use this reference to turn an external annotation or dataset-generation repo into UPA-native capabilities and cookbooks.
1. Inventory The Source Repo
Record the current pipeline as dataflow, not scripts:
Inputs: raw videos/images, manifests, metadata JSON, model checkpoints, endpoint environment variables, prompts, schemas, and labels.
Stages: what each script reads, writes, and requires.
Outputs: intermediate JSON, media chunks, crops, annotations, query files, DAFT files, visualizers, logs, and resume markers.
Dependencies: GPU-only steps, API-only steps, model cache, ffmpeg/OpenCV, external submodules, and secrets.
Concurrency: internal thread pools, batch workers, resumability, and skip conditions.
Prefer a small table:
| Source step | Reads | Writes | UPA target | Decision |
|---|---|---|---|---|
| chunk videos | raw videos | chunk mp4 + chunks.json | media_chunking | new generic service |
| dense captions | chunk mp4 | caption JSON | captioning | extend existing stage |
2. Classify Each Step
Use this order:
Cookbook-only: existing stage already supports the behavior through prompts, question banks, endpoints, classes, or
stage_args.Existing service extension: the behavior belongs to a current reusable stage such as captioning, detection/tracking, visual QA, reasoning (which now writes DAFT
task/artifacts), or training_export (dataset aggregation).New generic service: the behavior is a reusable primitive that multiple future pipelines could use.
External platform orchestration: the behavior is resource scheduling, distributed retry, queues, or fleet placement and should stay in OSMO, Airflow, or another platform layer.
Do not jump to option 3 until options 1 and 2 are ruled out.
3. Keep Branches Simple
Use as few follow-up branches as the review structure allows:
Skills/docs/cookbook guidance can live together when they are review-only.
A generic service primitive should own its task/service package, tests, Docker registration, and sidecar contract.
Runner updates should be limited to stage registration, argument plumbing, cookbook parsing, or registry support needed by that primitive.
Cookbook examples should sit on top of the service and runner support they require.
Avoid separate runner branches for every small cookbook or prompt adjustment.
4. Preserve The UPA Shape
Every migrated runtime stage should:
Accept
--input-file <jsonl>with coreDataEntryrows.Use
DataEntry.media_pathandDataEntry.data_path.Write under the scene
data_path.Put rich handoff evidence under
sidecars/<stage-or-node>/.Write discoverable state to
sidecars/pipeline_state.jsonwhen downstream stages need to find outputs.Register
[project.scripts]formake run.Register
[tool.build.images]formake build.Be dry-runnable or unit-testable without requiring a full dataset.
5. Author The Cookbook Last
Create the cookbook after service boundaries are stable. The cookbook should contain:
pipeline: videoorpipeline: image.workflow.nodeswhen dependencies matter more than a simple list.runtime:for GPU ids and model cache.endpoints:for VLM/LLM settings.Stage sections for stable knobs.
stage_argsfor service-specific or experimental flags.Repo-local sample paths, never user-specific dataset paths.
6. Validate Migration Readiness
Minimum validation:
Unit tests for new parser, service, or sidecar logic.
Contract test that each new service accepts
--input-file.Runner dry-run that shows expected stage order, images, mounts, prompts, endpoints, and stage args.
One tiny smoke input if models/endpoints are locally available.
MR note that lists unsupported behavior and follow-up capabilities.
