Remote-API pipeline for captioning, generating, and evaluating augmented camera data. Models are configured as HTTP endpoints; no local model weights are included.
Purpose
Use it to select a supported generation mode, author and validate
PipelineConfig YAML, configure captioning/evaluators, and run the
paidf-augmentation:1.2.0 container. It covers Cosmos Transfer/Predict,
Cosmos3 WSM controls, image editing, image-to-video, BYOM endpoints, and
quality gates.
Do not use this skill for training or fine-tuning models, deploying clusters or NIM endpoints, or unrelated application/database development.
Prerequisites
| Requirement | Detail |
|---|---|
| Docker | docker --version. The image is remote-API only — it bundles no Cosmos/torch weights, so plain remote inference needs no GPU and no HF_TOKEN. |
| NVIDIA GPU (conditional) | Only when a configured local stage requires CUDA or decodes H.264 in the augmentation container. See Limitations. |
| Endpoint URLs | One reachable URL per role used by the selected config. The examples name local Qwen services (Qwen/Qwen3.6-27B-FP8 on vlm, Qwen/Qwen2.5-14B-Instruct on llm), but those are not guaranteed to be running. Resolve every required role independently: keep each reachable configured endpoint and ask only for the missing role URLs. |
| API keys (conditional) | Only for endpoints requiring authentication. Pass the environment variable named by each endpoint's api_key_env; never hardcode values in YAML. Local unauthenticated endpoints need none. |
| Input media | A video/image reachable by multistorageclient (s3://, msc://, gs://, az://, or HTTPS). Local paths are allowed only when no external Cosmos evaluator is enabled; external evaluation requires checker-readable remote URIs. |
| Approved release commit (execution only) | A 40-character commit hash confirmed by the user as release-owner-approved or retrieved from the verified release manifest. Never invent it or rely on an unverified environment value. |
Inputs
Resolve each value in this precedence order: state file → explicit prompt arguments → agent context → user prompt. Ask the user only for what remains unresolved.
| Input | Required | Description |
|---|---|---|
config_path | Yes | Path to the pipeline YAML, e.g. configs/cookbook/video-data-augmentation/config_video_transfer_CT3_omni.yaml. If absent, pick a starting config from Supported Models and confirm with the user. |
input_media | Conditional | Source video/image → data[].inputs.rgb. Required for every mode except Cosmos Predict inference_type: text2world, where inputs may be null or rgb omitted. Overridable at run time via data.0.inputs.rgb=.... |
control_media | For precomputed control | Control video → data[].inputs.controls.<type>. For Cosmos3 WSM transfer, set controls.wsm; the client uploads it rather than exposing its local path to the server. |
output_paths | Yes | data[].output.{video,caption,metadata}; evaluation optional. |
model_name | Yes | augmentation.model.name — an endpoint id, a role, or a known model name. Free-form string, not an enum. |
endpoint_urls | Yes | One endpoints[] entry per role in use. |
api_key_env | If auth | Env-var name per endpoint; the value comes from the environment. |
target_attributes | No | captioning.llm.variables (e.g. weather_condition, lighting_condition). |
generation_params | No | augmentation.parameters — pass-through; only set knobs are sent. |
seed | No | Under augmentation.parameters. Before the first candidate, null resolves once to the generator/executor seed when available, otherwise the current Unix time. Retry n uses that resolved base seed plus n. pipeline.retry defaults to 1, so evaluation permits at most 2 candidates by default. |
BYOM model: endpoints, adapters, roles
Each endpoints: list entry declares role, url, wire model, and optional
id, adapter, api_key_env, and timeout. Roles are vlm, llm,
image_edit, video_transfer, video_predict, image2video, and evaluator.
augmentation.model.name resolves by endpoint id, then role, then the known
model-name mapping. Adapter contracts and full fields are in
configuration-schema.md.
Supported Models
When the user hasn't specified a model, choose from their input type and goal:
| Input Type → Goal | model.name | Role / default adapter | Input → Output |
|---|---|---|---|
| Video — change scene attributes (weather, lighting, style) | cosmos-transfer2.5 | video_transfer / nim | Video (+ controls) → Video |
| Video + precomputed WSM — follow world-state geometry/motion | A video_transfer endpoint id, e.g. cosmos3-transfer-wsm | video_transfer / openai.video.async | RGB video + WSM control + prompt → Video |
| Video + text — extend or predict continuation | cosmos-predict | video_predict / nim | Video+Text → Video |
| Text only — generate video from scratch | cosmos-predict (inference_type: text2world) | video_predict / nim | Text → Video |
| Image — edit specific attributes | image-edit | image_edit / nim (or openai.chat.completions, openai.images.edits) | Image → Image |
| Image — animate a first frame | cosmos3-image2video (or your Veo endpoint id) | image2video / openai.video.sync (Veo: openai.video.async) | Image + prompt → Video |
Key rule: use Cosmos Transfer for video scene changes, Cosmos Predict for
new/continued video, image edit for still edits, and image-to-video to animate a
frame. For Cosmos3 WSM, set data[].inputs.controls.wsm. Config selection
details are in config-decision-tree.md.
All models run via remote HTTP through one BaseExecutor; there is no local torchrun and no executor_type field.
Canonical Workflow
Follow this ordered decision tree; open the linked references only for the selected mode's details.
Config Correction Budget
config_attempts counts YAML versions, not validation or preflight calls. Keep
it across the whole workflow and never reset it.
- Set it to
1after initial authoring. - On a correctable error, if it is already
3, STOP and report the error. Otherwise increment it once and make one correction pass containing all currently reported YAML fixes. - Validate and preflight that edited version without another increment. Repeat rule 2 only if a later check finds another correctable YAML error.
STEP 0 — Mandatory Entry Gate
Execute this gate before every other step:
- Scope gate: if the request asks for training, fine-tuning, cluster/NIM deployment, or unrelated development, decline it and STOP.
- Input gate: resolve values using Inputs. If required values remain unresolved, request only those values and STOP until they are supplied.
- Proceed only when both gates pass and the input type and augmentation goal are known.
- Select the model from Supported Models using that input type and goal.
- Author the YAML in this order:
data,endpoints,captioning,augmentation,evaluators,pipeline, thendata_processing. Omit optional sections rather than creating placeholders. Setconfig_attempts = 1(config attempt 1 of 3). - Branch on the requested outcome:
- Configuration only or “do not execute”: do not build, launch, run preflight, or infer. A trusted runtime is an already-running container whose recorded immutable image ID/digest, checkout commit, and config mounts satisfy step 4. If validation was explicitly requested and such a runtime exists, run only the validation command and apply step 5's failure rules. Return the config (mark it unvalidated if validation was not run) and STOP.
- Inference/run requested: proceed to step 4.
- Prepare the runtime in these verifiable sub-steps:
a. Obtain
EXPECTED_RELEASE_REFfrom the user as a release-owner-approved full commit or retrieve it from the verified release manifest. b. Verify the Git working tree is clean. c. VerifyHEADmatchesEXPECTED_RELEASE_REF. If a release tag selected the revision, verify the tag first, then compare its resolved full commit. d. Build the image and capture its immutablesha256:image ID, or obtain a verified registry digest. e. Create thepaidfDocker bridge if needed and attach local services. f. Launch the container using the recorded image ID, thepaidfnetwork, required volume mounts,--entrypoint /bin/bash, and only the endpoint key variables named byapi_key_envplus the scoped storage credential variables required for the configured remote media. If any sub-step fails, STOP and report the exact failure and relevant remediation: clean a dirty tree, supply the approved revision, resolve a revision mismatch, check the Docker daemon/build, fix network setup, or fix the container launch. Do not continue with a partial runtime. - Inside the container, run the validation-only command in Usage Step 2 and
classify its result while preserving
config_attempts(current config attempt N of 3):- Success: if no external Cosmos evaluator is enabled, proceed directly to step 7. If one is enabled, proceed to step 6.
- Editable YAML/schema error: when required endpoint URL/model details are known, apply the Config Correction Budget rule, then rerun validation on that YAML version.
- Infrastructure/unknown input: for missing endpoint details, credentials, DNS, connectivity, or unhealthy services, do not edit speculatively. STOP and report the error or ask for the missing endpoint details.
- With external Cosmos evaluation enabled, preserve
config_attempts(current config attempt N of 3) and run its hard preflight gate before captioning/generation by querying/health,/checkers, and/dependency-graph:- Pass: require
/health.status == "healthy"; require every configuredchecks[].nameto exactly equal one string in the top-levelcheckersarray returned by/checkersand one key in the top-levelcheckersobject returned by/dependency-graph. Do not use substring, alias, or nested-field matching. Then proceed to step 7. - Config error: only a 4xx response from
/checkersor/dependency-graphwhose body explicitly identifies a configured checker name or invalid config field qualifies. Apply the Config Correction Budget rule, then return to step 5; revalidation does not increment the counter. - Infrastructure failure: any timeout, network/DNS error, 5xx response,
/healthfailure, unhealthy service, or missing deployed checker stops the workflow before generation. Create no candidate and report the root cause.
- Pass: require
- Enter inference only after step 5 succeeds and, when external evaluation is
enabled, step 6 passes. Run a candidate loop bounded to
pipeline.retry + 1candidates (retrydefaults to1, so the default maximum is 2). Resolve the base seed once before the first candidate as defined in Inputs; retrynusesbase_seed + n:- Generate a candidate and run its configured evaluators.
- On pass, accept it and exit the loop.
- On quality failure with attempts remaining, set the next seed to
base_seed + next_retry_number. Ifregenerate_caption_on_retry: true, regenerate the caption next; then generate the replacement. If false, generate the replacement immediately. - On exhausted quality retries, fail evaluation and exit the loop.
- On a service/contract failure, stop on the current candidate without
generating another. For external Cosmos evaluation, this means a
submission, polling, or discovery failure; a failed execution; a missing
or skipped result; or an invalid gating contract without a literal
top-level boolean
passed. Withpipeline.evaluation.strict: true(the default), applyretain_failures: its defaulttrueretains video, caption, metadata, and evaluation outputs for inspection; explicitfalsedeletes them. Withstrict: false, retain the files and report the evaluator failure without failing the sample.- If provider metadata contains
error_code: ambiguous_post, preserve the retained candidate, do not resubmit automatically, STOP, and defer to operator recovery. Follow the ambiguous-POST recovery flow.
- If provider metadata contains

Step 1: Verify, Build, and Launch the Docker Container
Set EXPECTED_RELEASE_REF to a release-owner-reviewed full 40-character commit,
never a tag or branch. If a signed release tag selects the revision, verify the
tag first and record its resolved full commit as EXPECTED_RELEASE_REF. Build
only from a clean matching checkout, then record the resulting immutable image
ID. For a prebuilt release, use its verified digest.
set -e
EXPECTED_RELEASE_REF="${EXPECTED_RELEASE_REF:?set a reviewed full commit ID}"
test "${#EXPECTED_RELEASE_REF}" -eq 40
case "$EXPECTED_RELEASE_REF" in *[!0-9a-fA-F]*) exit 1 ;; esac
test -z "$(git status --porcelain)"
test "$(git rev-parse HEAD)" = "$(git rev-parse "${EXPECTED_RELEASE_REF}^{commit}")"

-t paidf-augmentation:1.2.0 \

PAIDF_IMAGE_ID="$(docker image inspect --format '{{.Id}}' paidf-augmentation:1.2.0)"
case "$PAIDF_IMAGE_ID" in sha256:*) ;; *) exit 1 ;; esac
test "$(docker image inspect --format '{{.Id}}' paidf-augmentation:1.2.0)" = "$PAIDF_IMAGE_ID"
docker network inspect paidf >/dev/null 2>&1 || \

# Attach each local model container once, for example:
# docker network connect paidf vlm
# Example only: replace these with exactly the api_key_env names declared by
# the selected config; use an empty array when every endpoint is unauthenticated.
PAIDF_ENDPOINT_KEY_ARGS=()
# Authenticated example:
# PAIDF_ENDPOINT_KEY_ARGS=(-e VLM_API_KEY -e LLM_API_KEY -e VEO_API_KEY)
# Forward only credential names required by the configured remote media. Give
# checker containers their own scoped credentials in their deployment.
PAIDF_STORAGE_CREDENTIAL_ARGS=()
# S3-compatible example (include only the names your storage config requires):
# PAIDF_STORAGE_CREDENTIAL_ARGS=(-e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY \
# -e AWS_DEFAULT_REGION -e AWS_ENDPOINT_URL)

-v "$(pwd)/data:/workspace/data" \
--entrypoint /bin/bash \
"$PAIDF_IMAGE_ID"
Persist the captured sha256: ID and use it directly for every later launch;
never re-resolve the mutable tag as the launch target. For registry releases,
verify the signed manifest and use name:tag@sha256:<manifest-digest>.
- Networking: augmentation is an outbound-only client and does not publish
ports. Use the user-defined
paidfbridge for the augmentation container and every local model, Arbitrator, and checker container.cosmos-evaluatormay be a container/DNS hostname on that bridge; it is not a second bridge name. Change endpoint URLs from hostlocalhostaddresses to container DNS names, for examplehttp://vlm:8000/v1. The default bridge is sufficient when every endpoint is remote. - API keys: prefer a platform secrets manager that injects the required
environment variables. Otherwise, export only the required keys and forward
their names with
-e VAR_NAME; never mount or load a broad credential file. - No GPU needed for remote inference — add
--gpusfordata_processing.alignmentand any H.264 decode; pick a GPU not shared with a busy model server. Container runs as uid 10000; ensuredata/is writable (or--user "$(id -u):$(id -g)").
Warning: Never enable Docker host-network mode on shared, multi-tenant, or production hosts. It is permitted only when all three conditions hold: (1) a required host-local service cannot be moved onto the
paidfbridge, (2) the host is single-tenant and isolated with no other workloads, and (3) the user sends an explicit message in the current conversation choosing host networking after receiving a warning that it removes network namespace isolation. Silence, prior documentation, or an earlier unrelated approval is not acceptance. Do not select it automatically. Review pipeline-operations.md.
Step 2: Validate, Then Run (Inside the Container)
# Schema and cross-section preflight only: no endpoint calls or inference.
uv run --no-sync modules/cli.py --config configs/<config_file>.yaml --validate-only
# Run only after validation succeeds.
uv run --no-sync modules/cli.py --config configs/<config_file>.yaml
# With OmegaConf CLI overrides (dot-list syntax)
uv run --no-sync modules/cli.py --config configs/<config_file>.yaml \
data.0.inputs.rgb=/workspace/data/input.mp4 \
augmentation.parameters.seed=42
Environment variables: generation/captioning keys resolve as the api_key_env
var → the role's default env var. External Cosmos evaluation reads only the
variable explicitly named by its endpoint and fails initialization when that
variable is unset. Leave api_key_env off for unauthenticated endpoints.
LOG_LEVEL sets logging.
Configuration Schema
Configs are validated against PipelineConfig (modules/aug_utils/schema/) and have seven top-level sections. Author them in the canonical order above; YAML key order does not change runtime semantics. Full per-section YAML is in configuration-schema.md; runtime flow and common editing tasks are in pipeline-operations.md.
Troubleshooting
Run all inference and schema validation inside the Docker container for a consistent environment. For config-validation errors, runtime/endpoint errors, and typical per-stage timings, see troubleshooting.md.
Limitations
- Remote inference only. All models run behind remote HTTP endpoints; no local weights, no
torchrun, noexecutor_type, no Gradio executor. - GPU for configured local stages. Remote inference needs no augmentation-container GPU. A CUDA GPU is required by
data_processing.alignment(cupy) and by any local stage decoding H.264 because the image ships only the hardwareh264_cuviddecoder (software AVC decode is off for licensing). VP9 decodes in software. Video output is VP9-only. - External-evaluator media must be remote. When an external evaluator is enabled, schema validation rejects local
data[].inputs.rgb, control media, generateddata[].output.video, and configured companion media. Use checker-readables3://,msc://,gs://,az://, or HTTP(S) URIs; the pipeline does not upload local files solely for evaluation. - Inference only. This pipeline augments and generates media — it does not train or fine-tune models.
- Auth varies by endpoint. Hosted endpoints (e.g. Veo) need a key via
api_key_env; local endpoints (e.g. vLLM) need none.
