## What it does

The skill reads a parquet produced by gap analysis and checks each label against two criteria: whether it appears in the Mining source-pool CSV and whether AnomalyGen supports it. Matching ignores letter case, while the original labels and other columns remain unchanged.

It writes a parquet for each module plus `routing_summary.txt`, which records sample counts and routing decisions by label. The subsets may overlap. If the source-pool CSV is missing or empty, the Mining parquet has no rows but keeps the input schema. The skill also flags the case where both subsets are empty.

In a standalone session that was not started by the TAO skill bank plugin, run `tao-setup` first. AnomalyGen's eligible labels must match the integration and `ANOMALYGEN_SUPPORTED_LABELS` in `mdo-kratos-workflows/pipelines/sda/routing.py`; a mismatch can leave samples unrouted.

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/NVIDIA/skills/tree/HEAD/skills/tao-route-visual-changenet-samples/SKILL.md

## When to use it
- split weak VCN samples between Mining and AnomalyGen
- check which labels appear in the source pool
- identify labels accepted by neither module
- record routing decisions for each label

## Example prompts
- Split `kpi_gaps.parquet` into subsets for Mining and AnomalyGen.
- Show which labels in the VCN gap samples will reach neither module.
- Route the samples for the next SDA iteration and write the summary.

# TAO VCN Sample Routing Skill

> **Standalone install?** If this session was not initialized by the TAO skill bank plugin, run the `tao-setup` skill first (host preflight, credentials, cross-skill discovery).

You are the dispatcher between gap analysis and the augmentation modules in a VCN AOI SDA pipeline. Each augmentation module can only act on labels it knows how to handle:

- **k-NN Mining** can only mine real-image neighbors for labels that already exist in the **source pool CSV**. There is no point looking for `SHIFT` neighbors if the pool has no `SHIFT` rows.
- **AnomalyGen** (Cosmos SDG) can only generate synthetic anomalies for the classes its inference pipeline supports: `PASS`, `EXCESS_SOLDER`, `MISSING`, `BRIDGE`. A weak sample with a label outside this set is unroutable to AnomalyGen.

This skill runs **once per SDA iteration immediately after gap analysis**. It splits the gap-analysis parquet into one filtered parquet per module so each module operates on its own eligible subset, and it writes a human-readable summary of the per-label routing decisions.

The work is intentionally trivial: read a parquet, do two `.isin(...)` filters, write two parquets, write one summary. The skill exists to make those decisions auditable — every label must show up in the summary with a yes/no verdict for each module so a downstream reviewer can spot when a label is silently dropped because no module accepted it.

## Inputs

1. **`gaps_parquet`** — the gap-analysis output (typically `<exp_dir>/rca_results/<timestamp>/kpi_gaps.parquet` from `tao-analyze-gaps-visual-changenet`). Required columns: `filepath`, `label`. Other columns (`siamese_score`, `weakness`) are preserved verbatim.
2. **`source_pool_csv`** — VCN-format mining source pool CSV with a `label` column. Empty string or non-existent path is allowed; the mining subset will simply be empty in that case.
