Browse reusable Agent Skills, each with a clear purpose and practical guidance.
Check gate status for a Bitbucket PR by resolving the PR head commit, finding the gate merge commit, inspecting builds on that merge commit, and summarizing root-cause failures with actionable next steps.
Analyze current GraalPy periodic job failures for ROTA. Use when asked to triage, summarize, or plan work for current periodic job failures, starting from scripts/rota_ci_failures.py output, validating linked Jira issues, inspecting logs, forming hypotheses, reproduction commands, and implementation order.
Production readiness checklist for durable streams. Switch from dev server to Caddy binary, configure CDN caching with offset-based URLs, Cache-Control and ETag headers, Stream-Cursor for cache collision prevention, TTL and Stream-Expires-At for stream lifecycle, HTTPS requirement, request collapsing for fan-out, CORS configuration. Load before deploying durable streams to production.
Dump DEX files from a running Android app for unpacking/deobfuscation. Activate when the user wants to unpack an Android APK, dump DEX from memory, extract decrypted DEX files, or defeat class-loading packing.
Running durable stream servers. DurableStreamTestServer for development (Node.js, @durable-streams/server, not for production), Caddy plugin for production with Caddyfile configuration, data_dir for file-backed persistence, max_file_handles tuning, long_poll_timeout, server binary downloads for macOS Linux Windows, @durable-streams/cli tool setup, conformance test runner.
Deploy Yjs collaborative editing. YjsServer setup with compaction threshold, Caddy reverse proxy with flush_interval -1 for SSE, 3-layer architecture (Browser → Caddy → YjsServer → DS Server), Electric Cloud managed alternative with @electric-sql/cli provisioning. Load when deploying y-durable-streams to production or configuring server infrastructure.
Analyze an infrastructure incident alert and produce a structured response plan plus an executable on-call runbook. Use for incident, alert, on-call, and runbook requests.
Triage raw security-scan findings (hardcoded secrets, injection patterns, vulnerable dependencies) into a prioritized, actionable security audit report. Use for security audit, code audit, vulnerability triage, and risk review.
Publish a new kotlinx library API reference on kotlinlang.org/api via the TeamCity Kotlin DSL, the way kotlinx.coroutines, kotlinx.serialization, kotlinx-datetime and kotlinx-io are published. Use when wiring a Dokka-generated API reference for a Kotlin/* repo into the site. Covers the BuildParams consts + API_URLS entry, the VCS root, the three build objects (templates / pages / search index), their project registration, the kr.tree nav link, and the production navigation test. The worked example is kotlinx.collections.immutable (KTL-4524).
Buttercup-specific Langfuse wiring. Use when adding LLM tracing to a new LangChain/LangGraph entry point in this repo, attaching tags/metadata to existing chains, troubleshooting "no traces in Langfuse" against this codebase, or touching the Helm/values surface (`global.langfuse.*`, `langfuse-secret.yaml`, `common-env.yaml`). For platform-level Langfuse usage (CLI, instrumentation patterns generally, prompt migration, SDK upgrades), use the `langfuse` skill instead.
