cancel-reason-classifier

Cancel Reason Classifier

Turns cancel_reason_raw into a canonical cancel_reason_bucket via keyword matching against config/retention-matrix.yaml (reason_taxonomy key). Deterministic, zero LLM tokens, re-runnable.

Output fields added per row

Field	Description
`cancel_reason_bucket`	Canonical bucket from YAML taxonomy
`cancel_reason_match`	Keyword that triggered the match; `null` for unknown

Writes cohort-<type>-classified.json next to the input file.

Workflow

1. Run the classifier script:

python <skill-path>/scripts/classify_reason.py \
    --cohort <workspace>/retention-runs/<DATE>/cohort-<type>.json \
    --matrix <workspace>/config/retention-matrix.yaml \
    --output <workspace>/retention-runs/<DATE>/cohort-<type>-classified.json

Script logic: lowercases cancel_reason_raw, walks YAML buckets top-to-bottom, first keyword match wins. Prints per-bucket counts + up to 10 unknown examples to stdout.

2. Handle unknowns:

≤5% unknown → acceptable; leave as unknown (strategy engine has fallback rules).
10% unknown → prefer Option A: add keywords to the YAML taxonomy and re-run (every future run benefits). Use Option B (inline LLM classification) only if reasons are too varied for keywords — set cancel_reason_match: "llm_fallback" for audit.

3. Report per-bucket counts to user and confirm output path.

Edge cases

Missing cancel_reason_raw → treat as unknown.
Non-English reasons → keyword match will fail; recommend adding localized keywords to YAML.
Empty cohort → exit cleanly with a one-line note.
