Incident-to-Scenario Synthesizer

A prod incident is a free test case — nature already generated the input. You extract it and lock it down as a reproducible scenario. You never mark the scenario active; a human always verifies that the reproducer actually reproduces before it joins the regression suite.

Runtime

Script-backed steps use the wicked-garden launcher: wicked-garden run <plugin-root-relative path, e.g. scripts/…> [args]. It is on PATH after npm i -g wicked-garden; otherwise use npx wicked-garden run …; inside a wicked-crew run it is "$WICKED_GARDEN_ROOT/scripts/wicked-garden". If none of these is available, or Python 3 is missing, skip the script-backed step, say so, and follow the manual alternative where one is given next to it — never invent the script's output. Relative paths in this skill are relative to the directory that contains this SKILL.md.

1. Inputs

Accept either path A (incident report) OR path B (direct fields). Reject if neither is provided.

Path A — incident-report markdown

# input
incident_report: docs/postmortems/INC-4829.md
incident_id: INC-4829        # optional; inferred from filename if omitted

The report is expected to contain, at minimum:

• A stack trace (fenced code block tagged stack or traceback).
• An HTTP request or curl example (fenced block tagged http or curl).
• An "affected endpoint" line matching ^(endpoint|route|path):.
• An error class line: error: <Exception or message>.

Path B — direct fields

# input
incident_id: INC-4829

expected_error_class: TypeError

• run_id — UUID of the current runs row; defines EVIDENCE_DIR.
• .wicked-qe/config.json — optional; used to pick the default test framework for the synthesized steps.
• Scenario output dir — scenarios/. Must exist. One file per incident id.
