Audit agent configuration surfaces (AGENTS.md, CLAUDE.md, MCP servers, tool registrations, settings, hooks) for consistency, contradictions, and silent overrides. Returns impact-ordered findings tables.
Audit an agent's main loop for halting conditions, mutation budgets, loop breakers, sensitive-path guards, error recovery, and replayability. Returns impact-ordered findings tables.
Review a database schema migration for production safety: lock contention, backfill strategy, online vs offline, rollback path, foreign-key timing, replication lag. Returns impact-ordered findings tables.
Production readiness audit for a service: health checks, rollback strategy, runbook presence, observability wiring, capacity, dependencies. Returns impact-ordered findings tables.
Audit an AI eval suite for coverage, leakage between datasets, deterministic vs stochastic measurement, ladder correctness, and signal quality. Returns impact-ordered findings tables.
Generate or audit an incident runbook for an alert/service from code, dashboards, and alert rules. Output is a runbook plus a findings table of gaps. Findings follow the shared output contract.

| description | Reproduce reported bugs or symptoms by creating minimal, verifiable scripts in the DAX Lab. |
Use this skill when a user reports a bug, unexpected behavior, or failing symptom that needs to be isolated and verified before a fix is implemented.
Experimental reproduction scripts should ALWAYS be placed in the .dax/lab/ directory. DAX has Implicit Approval to write and execute any code within this directory. This keeps the main src/ tree clean and avoids unnecessary approval prompts.
.dax/lab/ (e.g., .dax/lab/repro_issue_123.ts).
bun run or the appropriate runtime and confirm it fails as expected with the reported symptom..dax/lab/.When the reproduction is complete, report:
Reproduction Script: Path to the script in .dax/lab/.Failure Symptom: The exact error or output that confirms the bug.Isolation Level: Confirmation that the bug is reproduced in isolation from unrelated logic.Verification Plan: How you will use this script to verify the upcoming fix.write_file to create the script in .dax/lab/.run_shell_command (e.g., bun run .dax/lab/repro.ts) to execute it.enforceRuntimeGuard logic which implicitly allows these actions in the Lab.
