on-call-handoff-patterns
Master on-call shift handoffs with context transfer, escalation procedures, and documentation. Use this skill when transitioning on-call responsibilities between engineers and ensuring the incoming responder has full situational awareness, when writing a shift summary that captures active incidents, ongoing investigations, and recent changes, when handing off mid-incident so a fresh engineer can take over the incident commander role without losing context, when onboarding a new engineer to the on-call rotation for the first time, or when auditing and improving the quality of existing handoff processes across teams.
What this skill does
# On-Call Handoff Patterns Effective patterns for on-call shift transitions, ensuring continuity, context transfer, and reliable incident response across shifts. ## When to Use This Skill - Transitioning on-call responsibilities - Writing shift handoff summaries - Documenting ongoing investigations - Establishing on-call rotation procedures - Improving handoff quality - Onboarding new on-call engineers ## Core Concepts ### 1. Handoff Components | Component | Purpose | | -------------------------- | ----------------------- | | **Active Incidents** | What's currently broken | | **Ongoing Investigations** | Issues being debugged | | **Recent Changes** | Deployments, configs | | **Known Issues** | Workarounds in place | | **Upcoming Events** | Maintenance, releases | ### 2. Handoff Timing ``` Recommended: 30 min overlap between shifts Outgoing: ├── 15 min: Write handoff document └── 15 min: Sync call with incoming Incoming: ├── 15 min: Review handoff document ├── 15 min: Sync call with outgoing └── 5 min: Verify alerting setup ``` ## Templates and detailed worked examples Full template library and detailed worked examples live in `references/details.md`. Read that file when you need the concrete templates. ## Troubleshooting **Incoming engineer misses a critical issue because the handoff document was incomplete.** Use the outgoing checklist as a gate: do not mark handoff complete until every section has at least one entry (or an explicit "none"). Make incomplete handoffs a blameless postmortem action item. **A 30-minute sync call is not possible due to timezone gaps.** Fall back to the async quick handoff template (Template 2). Supplement with a short Loom or voice memo walking through the watch list. Ensure the incoming engineer has a direct contact method if they have follow-up questions. **The incoming engineer inherits a mid-incident and is immediately overwhelmed.** Use the incident handoff template (Template 3) specifically. The outgoing engineer should remain available on Slack for 15 minutes after handoff, even if off-call, to answer clarifying questions. **On-call handoff documents are inconsistently formatted across teams.** Adopt the shift handoff template organization-wide and store completed handoffs in a shared location (wiki, Notion, Confluence). Link each handoff from the on-call schedule entry in PagerDuty. **Incoming engineer cannot verify their alerting is working before the outgoing engineer logs off.** Add a standard step: outgoing engineer fires a test alert and confirms incoming engineer receives it in PagerDuty and Slack before ending the overlap window. ## Related Skills - [incident-classification](../../skills/incident-classification/SKILL.md) — Classify and prioritize incidents that need to be included in the handoff document - [postmortem-facilitation](../../skills/postmortem-facilitation/SKILL.md) — Turn resolved incidents from the shift into structured postmortems

jax-development
IncludedUse this skill when the user is writing, debugging, profiling, refactoring, reviewing, benchmarking, parallelising, exporting, or explaining JAX code, or when they mention JAX, jax.numpy, jit, grad, value_and_grad, vmap, scan, lax, random keys, pytrees, jax.Array, sharding, Mesh, PartitionSpec, NamedSharding, pmap, shard_map, Pallas, XLA, StableHLO, checkify, profiler, or the JAX repo. It helps turn NumPy or PyTorch-style code into pure functional JAX, fix tracer/control-flow/shape/PRNG bugs, remove recompiles and host-device syncs, choose transforms and sharding strategies, inspect jaxpr/lowering/IR, and benchmark compiled code correctly.
nature-article-writer
IncludedDrafts, rewrites, diagnostically critiques, and style-calibrates primary research manuscripts for Nature and Nature Portfolio journals. Use when the user wants a Nature-style title, summary paragraph or abstract, introduction, results, discussion, methods, figure legends, presubmission enquiry, cover letter, reviewer response, or when a scientific draft sounds generic, jargon-heavy, structurally weak, or AI-ish and needs precise, broad-reader-friendly prose without inventing data, analyses, or references. Best for primary research articles and letters rather than reviews or press releases unless explicitly adapting one.
deckrd
IncludedDocument-driven framework that derives requirements, specifications, implementation plans, and executable tasks from goals through structured AI dialogue. Use when user says "write requirements", "create spec", "plan implementation", "derive tasks", "structure this feature", "break down into tasks", or "document this module". Also use for reverse engineering existing code into docs (/deckrd rev). Do NOT use for direct code writing — use /deckrd-coder after tasks are generated. Do NOT use when the user only wants to run or fix existing code without planning.
clinical-decision-support
IncludedGenerate professional clinical decision support (CDS) documents for pharmaceutical and clinical research settings, including patient cohort analyses (biomarker-stratified with outcomes) and treatment recommendation reports (evidence-based guidelines with decision algorithms). Supports GRADE evidence grading, statistical analysis (hazard ratios, survival curves, waterfall plots), biomarker integration, and regulatory compliance. Outputs publication-ready LaTeX/PDF format optimized for drug development, clinical research, and evidence synthesis.
handling-sf-data
IncludedSalesforce data operations with 130-point scoring. Use this skill to create, update, delete, bulk import/export, generate test data, and clean up org records using sf CLI and anonymous Apex. TRIGGER when: user creates test data, performs bulk import/export, uses sf data CLI commands, needs data factory patterns for Apex tests, or needs to seed/clean records in a Salesforce org. DO NOT TRIGGER when: SOQL query writing only (use querying-soql), Apex test execution (use running-apex-tests), or metadata deployment (use deploying-metadata).
accelint-ac-to-playwright
IncludedConvert and validate acceptance criteria for Playwright test automation. Use when user asks to (1) review/evaluate/check if AC are ready for automation, (2) assess if AC can be converted as-is, (3) validate AC quality for Playwright, (4) turn AC into tests, (5) generate tests from acceptance criteria, (6) convert .md bullets or .feature Gherkin files to Playwright specs, (7) create test automation from requirements. Handles both bullet-style markdown and Gherkin syntax with JSON test plan generation and validation.
