# Generate a probe skeleton from an uncovered cell (slice 4) Drive the layer-5 probe-corpus growth. Each invocation produces (or refreshes) a probe-skeleton YAML at `lineage/{repo}/probes/{P-NNN}.yaml`. The skeleton carries enough scaffolding for the maintainer to fill in the arrange / act / observe / assert blocks with the specific behaviour the probe pins; the cross-references + frontmatter are pre-populated from feature-flows.yaml. This skill is the maintainer-facing entry point for the canonical slice-4 deliverable per `adrs/drafts/dynamic-verification-layer.md`. ## Prerequisite - `lineage/{repo}/feature-flows.yaml` exists with at least one feature. - `lineage/{repo}/probes/` directory exists (`/probe-run` created it as part of slice 2). - `python3` available (the skill uses a small inline script to compute the next-available probe ID and parse feature-flows.yaml). ## Argument forms | Form | Behaviour | |---|---| | `/probe-define --feature <feature-id>` | Generate one skeleton for the first uncovered cell of that feature (lowest test_class index in `unit/integration/performance/security` order). | | `/probe-define --feature <feature-id> --test-class <class>` | Generate one skeleton for the specified test_class of that feature. | | `/probe-define --feature <feature-id> --all-uncovered` | Generate one skeleton per uncovered cell of the feature (up to 4 — one per test_class). | | `/probe-define --feature <feature-id> --out-id P-NNN` | Override the auto-derived probe ID
