AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
This skill executes a multi-stage, iterative workflow designed to improve object detection model performance through smart data augmentation. It manages a complete loop including zero-shot baseline inference, KPI analysis, per-class gap analysis, SigLIP-based embedding, unique-neighbor mining from a source pool, dataset staging, and retraining. The skill also provides a separate invocation for preparing the source pool, which involves pseudo-labeling raw images with Co-DETR, remapping classes, and converting data formats. It operates as a state-managed loop, ensuring consistency across iterations and providing automated reporting.
What it does
- Performs zero-shot baseline inference and KPI analysis on Grounding DINO models.
- Conducts per-class gap analysis to identify model weaknesses.
- Mines unique, high-value training samples from a prepared source pool using SigLIP embeddings.
- Stages mined data into the ODVG format for iterative model retraining.
- Prepares source pools by pseudo-labeling raw images and converting them to the required ODVG format.
- Maintains a persistent state machine to track progress and ensure auditability across training iterations.
When to use it
- When you need to improve the mAP of a Grounding DINO model through iterative data mining.
- When you have a large pool of unlabeled images that need to be pseudo-labeled and mined for training.
- When you want to automate the gap analysis, mining, and retraining cycle.
- When you need to prepare a source pool of images for use in a DEFT-based detection workflow.
Advantages
- Automates complex, multi-step data augmentation and training loops.
- Reduces manual effort in identifying and labeling high-value training data.
- Ensures consistent data processing and state management across iterations.
- Provides clear visibility into model performance trends through automated KPI reporting.
Usage examples
- “run the DEFT OD loop”
- The agent initiates the iterative mining and retraining process, starting with baseline inference and gap analysis.
- “prep the source pool”
- The agent runs the Co-DETR pseudo-labeling and embedding pipeline to prepare your raw images for future mining.
- “mine and retrain my detection model”
- The agent performs gap analysis, mines new samples from the source pool, stages the data, and triggers a retraining iteration.
- “improve OD mAP with gap analysis and mining”
- The agent executes the full DEFT loop to identify performance gaps and iteratively grow the training dataset to boost mAP.

Execution Contract
Treat this as a disk-backed state machine, not as a prose recipe.
Preserve every explicit user value.
epoch 1meanstrain.num_epochs=1; a spec value or documented default applies only when the user did not supply that parameter. Show the source of every run parameter (user,spec, ordefault) in the Pre-Flight Summary.After the user approves the Summary, initialize
deft_state.jsononce withscripts/init_deft_state.py. Never hand-author or reinitialize it on resume.Run every bundled or inline host-Python command through
scripts/deft_python.sh. On startup, after context compaction, before every stage, and before any completion claim, run:<skill_root>/scripts/deft_python.sh \ <skill_root>/scripts/audit_deft_run.py --results-dir "${RESULTS_DIR}"If it prints
DEFT_RUN_STATUS=INVALID, stop and repair the listed disk inconsistency; do not launch another stage. Read the path printed asread_before_actionbefore continuing.Invoke the mapped underlying skill after reading the DEFT overlay. Do not replace a missing or unread stage reference, or a failed skill call, with guessed shell commands, inline Python, a different output tree, or fabricated data.
Commit every stage with
scripts/commit_stage.py; it verifies artifacts, updatesdeft_state.json, appends exactly one orderedloop_log.jsonlevent, and rolls back if its audit fails.Claim the loop complete only when this exits zero:
<skill_root>/scripts/deft_python.sh \ <skill_root>/scripts/audit_deft_run.py \ --results-dir "${RESULTS_DIR}" --require-complete
Context Discipline
Load references just in time. Run the audit, read only its
read_before_actionfile and the current stage's named section, then act. Never preload all references.Redirect verbose train, inference, and Docker output to files. Inspect at most the final 40 lines or a one-line artifact check; never print a full spec, state file, or loop log into the conversation.
A Skill-tool call loads stage instructions; it does not start a background orchestrator. Continue the documented stage in the parent immediately after it returns.
When to Use This Skill
Use this skill when the user wants an agent to run the full smart-data-augmentation loop for a TAO Grounding DINO detection model: zero-shot baseline, gap analysis, mining, dataset growth, and retraining across N iterations.
"Run the DEFT OD loop"
"Run smart data augmentation for grounding dino"
"Mine more training data for my detection model and retrain"
"Improve detection mAP with gap analysis and unique-neighbor mining"
Also use it to prepare the source pool, which is a separate run that completes before the
loop launches (see ## Two Invocations: Prep, Then Loop):
"Prep the source pool"
"Pseudo-label my unlabeled images for mining"
"Build the mining pool from these raw images"
Do not use this skill for a single standalone TAO training run, one-off inference, or gap analysis alone. Invoke the relevant leaf skill directly instead.
Scope: Grounding DINO + ODVG
This loop targets Grounding DINO with ODVG training annotations (tmm_odvg.jsonl + labelmap.json), matching the reference pipeline. dataset.train_data_sources is a list; each iteration appends one new ODVG source rather than rewriting a combined CSV. DINO and RT-DETR (COCO) are not supported by this workflow — use the leaf skills directly for those.
The loop does not train at baseline. It evaluates the supplied zero-shot / pretrained checkpoint as iteration 0 and only trains from iteration 1 onward, once mining has produced data to add.
Two Invocations: Prep, Then Loop
The source pool is prepared by its own run, before the loop launches. They are separate because a pool is prepped once and then serves many loop runs — coupling them would re-label and re-embed the same images on every launch.
| Invocation | Does | Produces |
|---|---|---|
| "Prep the source pool" | Co-DETR pseudo-labels raw pool images, folds to the target classes, converts KITTI→COCO→ODVG, verifies, embeds | coco.json, odvg/, source_embeddings.parquet, pool_report.json |
| "Run the DEFT loop" | baseline → iterations | checkpoints, KPI, the mAP trend |
Follow references/prep-source-pool.md for the first. The loop then takes those four paths as
inputs; Pre-Flight validates them and init_deft_state.py pins them, so a run cannot reach
mine with no corpus to search.
Launch Intake
Do not ask which platform to run on. This workflow supports one: every stage launches
with docker run, and its compatibility line requires docker plus the
nvidia-container-toolkit. The bank's rule in AGENTS.md is to treat a single supported
platform as the selection and only ask when an application supports several — asking here
would offer a choice that nothing downstream can act on.
Read tao-run-on-docker's ## Credentials section.
Never ask for or read credential values. Check only whether the required environment variable is set; if unset, tell the user which variable to export.
Agent Behavior
There is exactly one user gate: pre-flight confirmation. Print the Pre-Flight Summary (see
references/preflight.md), then STOP and wait for explicit approval ("go", "yes", "looks good"). Do not launch any side-effecting step before that approval.After the gate, the skill is fully autonomous. Run the entire loop without asking for confirmation. Only stop if a step fails with an unrecoverable error or a hard-stop gate fires. Print a one-line status update at each stage milestone.
Auto-mode required. The post-gate loop fires constant side-effecting calls; without auto-accept mode it stalls on the first prompt. Remind the user at the Pre-Flight Summary to enable auto-mode (shift+tab) before approving.
Non-zero command rule. Never repeat an unchanged failed command. Read the final error block, map it to the loaded stage reference, make one evidence-based correction, and rerun its documented verification. If the reference does not cover the failure, commit
status=errorand halt.Revised plan. If any run parameter changes after the Summary was shown, re-run Pre-Flight and show an updated Summary before proceeding.
Workflow
Full detail in references/pipeline-and-state.md.
Pre-Flight. Run every check in
references/preflight.md. Resolve workspace, specs, annotations, the zero-shot checkpoint, the source-pool embedding parquet, and container images. Hard stop only on missing input you cannot resolve yourself.Prep (once, before baseline). If the source pool is not already labeled and embedded, pseudo-label it with Co-DETR, fold the predictions onto the user's target classes, convert KITTI→COCO→ODVG, and embed the pool. Skip any step whose output already exists — no script does this for you, so check before each step. See
references/prep-source-pool.md.Baseline (iter_0) — no training. Run
inferencewith the supplied zero-shot / pretrained checkpoint, thenkpi_analyze. Seedtrain_grounding_dino.yamlfrom the user's template for later iterations to extend.Iterate. For each iteration 1..
max_iterations, run the seven stages in order:gap_analysis→embed→mine→stage→train→inference→kpi_analyze. Each iteration'sgap_analysisconsumes the previous phase's inference labels. Between stages run the audit and follow its one-line disk-backed next action.Stop when
max_iterationsis reached or a hard-stop gate fires. mAP is reported, not gated — the loop does not early-exit on a metric target.The report renders itself.
results/DEFT_Loop_Report.mdis written byinit_deft_state.pyand re-rendered by every acceptedcommit_stage.pycall. Do not spawn a subagent for it and do not compose it by hand; to refresh it out of band, runscripts/render_report.py --results-dir "${RESULTS_DIR}".
All stages run inline in the parent context. Prefer invoking the underlying tao-skill-bank:* skills via the Skill tool, layering loop conventions on top via the matching references/*.md overlay.
Using Bundled Scripts
Run bundled scripts through <skill_root>/scripts/deft_python.sh. Resolve every path argument to an absolute host path first. Use commit_stage.py for all state and log writes. See references/scripts-and-agents.md.
Stage Reference Modules
Each stage maps to one underlying skill or to bundled glue. Read only the current stage's overlay, then invoke.
The overlays are written against two loop variables that Pre-Flight sets and every stage uses: N, the current iteration number, and PHASE, which is baseline or iter${N}. They are stated here because a stage overlay is read on its own — see references/preflight.md for the full set.
If an overlay is missing, stop and ask the user to reinstall the plugin — the loop cannot run a stage whose settings it does not have. If a mapped skill is unavailable, do not stop and do not improvise: fall back to the overlay's documented docker run as described in references/scripts-and-agents.md, and commit that stage with --execution-path direct-container instead of the documented skill. The overlay carries everything the invocation needs, so the fallback produces the same artifacts.
On a runtime without a Skill tool (Codex, for example), the mapped skills are still on disk under the plugin root: read skills/<layer>/<name>/SKILL.md there for the invocation contract, then run it through the direct-container fallback above, committing the stage with --execution-path direct-container. On such a runtime that fallback is the expected route for every stage, not an exception.
| Stage | Overlay | Underlying skill |
|---|---|---|
prep (once) | references/prep-source-pool.md | tao-skill-bank:tao-train-codetr + tao-generate-image-embeddings (+ bundled glue) |
gap_analysis | references/tao-analyze-gaps-od-map.md | tao-skill-bank:tao-analyze-gaps-od-map |
embed | references/tao-generate-image-embeddings.md | tao-skill-bank:tao-generate-image-embeddings |
mine | references/tao-mine-od-images.md | tao-skill-bank:tao-mine-od-images |
stage | references/stage-mined-data.md | (bundled glue — no leaf skill) |
train, inference | references/grounding-dino.md | tao-skill-bank:tao-train-grounding-dino |
kpi_analyze | references/tao-analyze-detection-kpi.md | tao-skill-bank:tao-analyze-detection-kpi |
Path rule (invariant). Record absolute host paths under ${RESULTS_DIR}. Mount "$WORKSPACE:$WORKSPACE" with identical host and container paths. TAO's update_results_dir appends the task name to results_dir, so passing results_dir=X to train writes X/train/ and to inference writes X/inference/. Never append the subdirectory yourself.
Data, Pre-Flight, Pipeline, and State References
| Topic | Reference |
|---|---|
| Data contract, ODVG layout, source pool, output tree | references/data-layout.md |
| One-time source-pool prep (pseudo-label, remap, convert, embed) | references/prep-source-pool.md |
| Pre-Flight checks, defaults, Summary template | references/preflight.md |
| Pipeline stages, state schema, loop-end sequence | references/pipeline-and-state.md |
| Bundled scripts, glue, the report renderer, stage table | references/scripts-and-agents.md |
max_iterations defaults to 1 — one mine, train and score pass, the smallest run that yields a comparison against the baseline. Confirm it with the user when they have not said how many iterations they want; an unattended run takes the default rather than stopping to ask.
Gating
Run the full Pre-Flight, print the Summary, then STOP at the one user gate. After approval, run the baseline and the seven-stage iteration pipeline.
Hard-stop and never auto-retry on: any stage status=error; a missing or zero-row source-pool embedding parquet; a zero-row mining result when weak images were present; a missing ODVG annotation source; an image/annotation mismatch after staging; or a train exit that emits no new iteration checkpoint. The loop stops when max_iterations is reached or an unrecoverable gate fires. Each terminal path commits loop_stop through commit_stage.py, then follows the loop-end sequence in references/pipeline-and-state.md.

DEFT OD — KPI Analyze Stage Overlay
Layers loop conventions on top of tao-skill-bank:tao-analyze-detection-kpi. Read that skill's SKILL.md for the full field reference and pitfalls.
When to invoke
Twice per phase boundary:
Baseline: after the zero-shot
inference, as the final baseline stage.Iteration N: after
inference, as the final stage of the iteration.
No pre-KPI label filtering
The reference pipeline optionally filtered inference labels before scoring — exclude-ROI (masking out a region of the frame) and exclude-PIC (dropping person-inside-car detections) — and its exp7 configuration ran with PIC enabled.
This loop applies neither. Both are dataset-specific label cleanups for one intersection deployment, not general OD loop mechanics, so kpi_analyze scores the raw inference labels as written.
The practical consequence: mAP here will not match exp7's numbers, because exp7's persons-inside-cars were removed from ground truth before scoring. The trend across iterations is still valid — it's a consistent measurement — but do not compare the absolute values against the reference experiment's.
mAP is reported, not gated
This loop does not early-exit on a metric target. kpi_analyze records where the model stands so the report can show the trend across iterations; a regression does not stop the loop and does not trigger a retry. The loop runs until max_iterations or a hard-stop gate.
Do not add metric-based stopping logic here. If the user wants target-gated stopping, that is a change to the workflow contract, not something to improvise mid-run.
Spec
Do not hand-write it. Emit analytics default_specs, then apply the overlay —
assets/overlays/kpi_analyze.yaml holds every documented setting, so a field
cannot keep a TAO default just because nobody typed it:
PHASE=<baseline|iter${N}> # names the container and this phase's output tree
KPI_SPEC="${RESULTS_DIR}/${PHASE}/kpi_spec.yaml"
<skill_root>/scripts/deft_python.sh <skill_root>/scripts/emit_default_spec.py \
--stage kpi_analyze --ds-image "$TAO_DS_IMAGE" \
--out "$KPI_SPEC"
<skill_root>/scripts/deft_python.sh <skill_root>/scripts/apply_spec_overrides.py \
--spec "$KPI_SPEC" \
--apply-workflow-defaults <skill_root>/assets/overlays/kpi_analyze.yaml \
--set results_dir="${RESULTS_DIR}/<phase>/kpi" \
--set kpi.conf_threshold=<state.config.kpi_conf_threshold> \
--set visualize.tag=<phase> \
--set data.kpi_sources="[{image_dir: <KPI images>, ground_truth_ann_path: <KPI labels>, inference_ann_path: ${RESULTS_DIR}/<phase>/inference/labels}]" \
--set data.mapping=<class-mapping YAML> \
--set data.image_dir=<KPI images> \
--set data.ann_path=<KPI labels> \
--report-json "${RESULTS_DIR}/<phase>/kpi_overrides.json" \
--require-no-mandatoryEverything in the overlay is fixed; everything in --set is a path or a phase
label. A --set naming a key the overlay already set is rejected — that
collision is the drift the split exists to prevent.
The resulting kpi: block:
kpi:
iou_threshold: 0.5
conf_threshold: 0.0 # from state; the run's own setting — see below
num_recall_points: 101 # COCO-style interpolation; 11 selects the VOC curve
ignore_sqwidth: 0 # score every box, including small ones
filter: false
is_internal: falseconf_threshold is the one value here the run owns. init_deft_state.py freezes it as
config.kpi_conf_threshold and every phase is scored at that same value, so the baseline
and each iteration stay comparable. Read it from state rather than retyping it.
The default is 0.0, and that is the value to score at: inference writes its labels at
0.0, so scoring there covers the full PR curve. A higher threshold truncates the
low-confidence tail and produces a number that cannot be compared against a run scored at
0.0. --kpi-conf-threshold exists so a run that needs a different operating point can
say so once, at init, and have every phase honour it.
These values are the leaf skill's defaults too
tao-analyze-detection-kpi ships the same conf_threshold: 0.0, num_recall_points: 101
and ignore_sqwidth: 0, so delegating to it and applying this overlay agree by default.
They stop agreeing on conf_threshold as soon as a run sets its own, which is why this
stage passes it explicitly rather than relying on the leaf's default. Apply the overlay
and the --set anyway: the agreement is a fact about the current versions, not a
guarantee, and a spec that states its own scoring settings is auditable after the fact.
Scoring at more than one confidence threshold
Inference runs at 0.0, so the labels carry every detection and this stage can score them
at any threshold without re-running inference — re-apply the overlay with
--set kpi.conf_threshold=<t> and a distinct results_dir per point, since
kpi_calc.csv is written unconditionally and a shared directory keeps only the last. No
--allow-workflow-default-override is needed: the overlay no longer pins this key.
conf_threshold selects from what inference wrote; it cannot recover a box inference
dropped.
Only a result at config.kpi_conf_threshold is comparable to the loop's reported mAP. The
loop scores every phase once, at that one value; sweeps are a diagnostic.
input_format is uppercase here. analytics kpi_analyze accepts only KITTI or COCO. This differs from gap_analysis object_detection in the same container, which takes lowercase kitti / coco. The two stages in this loop therefore spell the same format differently — that is expected, not a typo to "fix".
Keep visualize.platform: local. The wandb path needs credentials and a reachable endpoint; a loop stage should not depend on either.
is_internal must stay false. Setting it true drops every class except person and appends a Summary row, silently changing what the report means.
Narrow the mapping to the target classes first
The user's mapping usually names more classes than the run targets. Scoring an untargeted class adds a constant-0 AP row and averages it into the mAP, so the number stops being comparable with any run that did not:
<skill_root>/scripts/deft_python.sh <skill_root>/scripts/prepare_mapping_for_kpi_analyze.py \
--mapping "<the user's class mapping>" \
--target-classes "<comma-separated target classes>" \
--out "${RESULTS_DIR}/<phase>/kpi/mapping.yaml"Pass the narrowed file as data.mapping, not the user's original.
Invocation
Launch it detached. Runtime scales with the KPI set, and the baseline is the
slowest phase to score because inference writes its labels at conf_threshold: 0.0, so
every detection is present to be read. The mAP
appears only on stdout, and a foreground docker run | tee loses it if the client
dies while the container keeps running — name the container, redirect to the log, and
wait on the log with await_stage.py:
docker run -d --name "deft_${PHASE}_kpi" ... > /dev/null
<skill_root>/scripts/deft_python.sh <skill_root>/scripts/await_stage.py \
--artifact "${RESULTS_DIR}/<phase>/kpi/kpi_calc.csv" --timeout-sec 5400
docker logs "deft_${PHASE}_kpi" > "${RESULTS_DIR}/<phase>/kpi/kpi_analyze.log" 2>&1Pass --gpus all even though the scoring itself is CPU-bound: the TAO launcher calls
nvidia-smi -L unconditionally at startup, so omitting it fails with
FileNotFoundError: 'nvidia-smi' before any work begins.

analytics kpi_analyze -e "$KPI_SPEC" 2>&1
# Detached, and NOT --rm: the mAP exists only on this container's stdout, so removing
# it on exit discards the number. Wait on the artifact, then capture the log, then
# remove the container yourself:
# await_stage.py --artifact "${RESULTS_DIR}/<phase>/kpi/kpi_calc.csv" --timeout-sec 5400
# docker logs "deft_${PHASE}_kpi" > "${RESULTS_DIR}/<phase>/kpi/kpi_analyze.log" 2>&1
# docker inspect -f '{{.State.ExitCode}}' "deft_${PHASE}_kpi" # check before trusting it
# docker rm "deft_${PHASE}_kpi"The aggregate mAP is printed to stdout only — nothing writes it into kpi_calc.csv,
which carries one row per class and no aggregate row. Do not depend on holding that stream:
the stage runs tens of minutes on a large KPI set, and a driver whose shell calls time out,
a dropped pipe, or a container reaped before docker logs runs all lose the one number the
loop compares phases on.
Derive it from the CSV instead. The aggregate is the unweighted mean of the per-class APs, so it recomputes exactly:
MAP_VALUE=$(<skill_root>/scripts/deft_python.sh <skill_root>/scripts/summarize_kpi.py \
--kpi-csv "${RESULTS_DIR}/${PHASE}/kpi/kpi_calc.csv" \
--expect-classes <number of target classes> | tail -1)It writes kpi_summary.json beside the CSV and prints the value for --map-value.
--expect-classes is what makes the mean trustworthy: the CSV has no class column, so a
row that is not a target class — the Summary row kpi.is_internal: true appends — would
shift the mean silently. A disagreement is an error instead.
Still capture the log. On an image predating tao-data-services#31 it is the only place the per-row class names appear, and it remains the record of what the stage actually reported.
Outputs
| Artifact | Path |
|---|---|
| Per-class metrics | ${RESULTS_DIR}/<phase>/kpi/kpi_calc.csv |
| PR curve plot | ${RESULTS_DIR}/<phase>/kpi/ |
| Captured log (class names for the CSV rows) | ${RESULTS_DIR}/<phase>/kpi/kpi_analyze.log |
| Aggregate mAP | ${RESULTS_DIR}/<phase>/kpi/kpi_summary.json |
kpi_calc.csv columns: Sequence Name, class_name, TP, FP, FN, TN, Pr, Re,
Acc, AP.
class_name arrived with tao-data-services#31. On an image built before it the column is
absent and the rows are unlabeled — one per class, in the order kpi_analyze.log prints
them. summarize_kpi.py handles both: with the column it labels each AP and drops any
Summary row by name; without it, --expect-classes is the only thing standing between a
stray row and a quietly wrong mean. Pass --expect-classes either way.
Sequence Name is derived as the second-to-last component of image_dir, not configured. Keep image_dir free of a trailing slash and laid out so that component is the sequence identifier you want; two sources can otherwise collide under one name.

target class has no ground truth in the KPI set; that holds for every phase, since all of
them score the same set, so commit the stage with --status error and fix the KPI mapping
or the class set.
