Calculate and debug Flexbox layout math for flex base size, flex-basis, flex-grow, flex-shrink, the flex shorthand, fractional grow values, and min/max constraints. Use when flex items resize unexpectedly, when distributing free space along one axis, when comparing flexbox with grid, or when deriving predictable card, nav, toolbar, and row layouts.
Generate, modify, or debug Kestra Flow YAML by fetching the live flow schema and applying the same guardrails used by the Kestra AI Copilot. Use when users ask to create, write, update, or fix a Kestra flow.
Writes, edits, and debugs Mermaid diagrams (flowchart, sequence, class, state, ER, Gantt, pie, mindmap, timeline, quadrant, git graph, XY, Sankey, architecture, journey, kanban, block). Use when the user says "draw a diagram", or when the user asks for a diagram, flowchart, ERD, or Mermaid code, or when a Mermaid diagram fails to parse or render.
Read the live Hermes desktop DOM/CSS over CDP.
Make Sentry stack traces readable — upload source maps for JavaScript/TypeScript, or debug files for native and mobile (dSYM, ProGuard/R8, NDK symbols, Dart obfuscation maps, .NET PDBs). Use when frames in Sentry show minified names, bundled paths, hex addresses, "unknown", or method names with no file/line, instead of your original source.
Diagnose, repair, and verify follow-up changes to an implementation already in progress.
Inspect and operate Inngest Cloud through its OAuth MCP connection. Use for deployed apps and functions, failed or slow runs, traces, events, environments, sessions, experiments, and Insights. Prefer this for Cloud operations when MCP tools are available; use CLI or REST skills for explicit terminal or HTTP tasks.
Guide deterministic runtime investigations in environments using Lightrun MCP tools, with preflight gating, recovery/resume rules, evidence-first diagnosis, PR-first fix proposal delivery, and local source-code fallback only when PR creation is not possible.
Diagnose and fix failed, stuck, slow, or incorrectly blocked Paperclip tasks and runs. Use with a task/run URL or failure report to trace the root cause, prove a regression red then green, check second-order effects, verify the real workflow, and deliver a PR with passing checks.
Debugs failed, crashing or hung Pathways on Cloud workloads (JAX training or inference on Cloud TPU in GKE, run as a JobSet, PathwaysJob or LeaderWorkerSet). Reads Cloud Logging for every Pathways container (user workload, IFRT proxy, pathways-rm, pathways-worker, colocated Python sidecar), node kernel logs and GKE events, then reports the earliest real error, the root cause and a fix. Use when a Pathways workload fails to start, crashes, restarts or stops making progress, or shows errors such as IFRT proxy connection failures, DEADLINE_EXCEEDED lost connection to peer, host OOM kills, ImagePullBackOff, or JAX and Pathways version mismatches. Don't use for GKE workloads that don't use Pathways, or for creating clusters or deploying new Pathways workloads.
Use when kernel threads block on driver synchronization or Verifier reports a lock-order violation; build an owner/waiter graph. Not for treating every watchdog stop as a deadlock or listing every lock type with !locks.
Subprocess and concurrency discipline for Python: how to run external programs safely, and how to pick the right concurrency model instead of the habitual one. Use when spawning processes with subprocess or asyncio subprocesses, writing threading or ThreadPoolExecutor code, using multiprocessing or ProcessPoolExecutor, sizing worker pools, bounding fan-out, or diagnosing deadlocks, hangs, orphaned children, and zombie processes. Covers argv vs shell, timeouts that kill the whole process tree, pipe deadlocks, start methods (spawn/forkserver/fork), pickling limits, GIL and free-threading, and cancellation. For event-loop and coroutine rules (TaskGroup, blocking calls, cancellation), use python-async-best-practices instead.
