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.

CDF Workflow Runner Debugging

Use this skill when the user asks for an end-to-end agentic auto-labeling run, a container-by-container experiment, generated container command review, or a data-flow debugging pass, especially when mixed-resolution inputs may need conditional super-resolution.

The primary executor is the workflow-runner service from services/workflow_runner, not ad hoc agent-authored docker run commands. Follow the numbered Workflow below for the exact procedure and its gates. OSMO or Airflow should own scheduling, distributed execution, retry policy, queues, and resource placement; this skill is only repo-specific runner usage and debugging guidance.

Workflow

The flow is a linear spine Step 1 -> 2 -> 3 -> 4 -> 5 with two explicitly bounded loops and four terminal states: review-only report (Step 4), invalid-plan stop (Step 3), validated success (Step 5), and escalation after a failed rerun (Step 5). Steps 1-3 only inspect and plan (no side effects); Step 4 is the only step that executes, builds images, or mutates outputs, and runs only with explicit user approval.

  1. Identify the cookbook or explicit stage sequence.

  2. Run a dry plan: make run SCRIPT=workflow-runner:main ARGS='--cookbook-file <config> --container-dry-run'.

  3. Is the plan valid? (single decision)

    • Trigger: the dry-run plan from Step 2 is available.

    • The plan is valid only if all hold: selected stages appear in the fixed canonical relative order (see Guardrails) with no retired daft_export stage; images, build targets, mounts, endpoints, and GPU settings are correct; when SR is selected, the SeedVR runtime is baked into the image and checkpoints exist under the model cache; and, for mixed-resolution inputs, SR --resolution-policy auto is set and the caller media_path / active-media handoff is preserved.

    • Invalid -> fix the cookbook, stage list, build flags, mounts, endpoints, or model availability and return to Step 2. Bounded loop: at most three correction passes; if still invalid, STOP and report the blocker (terminal).

    • Valid -> go to Step 4.

  4. Is execution requested and approved? (execution gate)

    • Trigger: a valid plan from Step 3.

    • Dry-run / command-review only, or the user says not to execute -> report the plan and STOP (terminal); do not execute, build images, or mutate outputs.

    • Execution requested and explicitly approved -> run the whole selected pipeline once through workflow-runner:main. The runner executes the selected stages internally in canonical order; the agent does not re-invoke per stage. Choose the build mode as a value, not a branch: --container-ensure-images build-if-missing builds only missing images; --container-build-images rebuilds all images. Continue to Step 5.

  5. Validate outputs. After the single run completes, confirm each selected stage produced its expected outputs, in canonical order. This is a finite check over the selected stages, not a re-execution loop.

    • All expected outputs present -> report success (terminal).

    • A stage failed or is missing outputs -> follow Failure Handling in runner-debugging-patterns.md: stop unless the stage is optional; after fixing the root cause, rerun from the failed stage. Bounded loop: at most one rerun per fixed root cause - if the same stage fails again with no new cause, STOP and escalate with the saved log and exact command (terminal).

Examples

Inspect the plan, execute while building only missing images, then validate:

# Inspect the generated container plan (no execution)
make run SCRIPT=workflow-runner:main \
  ARGS='--cookbook-file cookbooks/video_data_augmentation/configs/pipeline_video.yaml --container-dry-run'

# Execute, building only images that are missing
make run SCRIPT=workflow-runner:main \
  ARGS='--cookbook-file cookbooks/video_data_augmentation/configs/pipeline_video.yaml --container-ensure-images build-if-missing'

# Validate stage outputs before reporting success
ls -lhR output/auto_labeling/<scenario>/

Guardrails

  • Do not bypass the runner for production experiments unless the user is explicitly debugging a single container command.

  • Do not modify the original media_path in caller-authored input JSONL; runtime components such as prepare_input may rewrite data_entry.media_path to sidecars/active.*, and downstream code such as SceneContext.from_input(data_entry.media_path) is expected to operate on those runtime rewrites.

  • For mixed-resolution video, prefer SR --resolution-policy auto over unconditional SR so high-resolution clips keep the existing active media.

  • Do not mount broad host paths when runner-managed media/data/config/cache mounts are sufficient.

  • Prefer existing make build IMAGE=... registrations and runner image flags over ad hoc image names.

  • Plain stages dry-runs follow the canonical relative order. Cookbooks using workflow.nodes follow their validated stable topological order and may repeat a stage. Confirm every plan/result/log entry preserves its node ID and repeated nodes use distinct sidecar namespaces. Shared stage_args apply to every occurrence; node args are appended last.

  • The single daft_export stage is retired: DAFT task/ writing belongs to reasoning, and dataset aggregation belongs to the new training_export stage. Do not plan, run, or debug a daft_export stage.

  • The person_attribute_search stage (Visual Attribute Search product) builds the event-and-person-attribute-search-service image; the stage key stays person_attribute_search.
