on-call-handoff-patterns

on-call-handoff-patterns is a skill for Claude Code from EngineerWithAI/engineerwith-agents. It costs 40 tokens per session (2,963 once invoked), scanned A, a copy of on-call-handoff-patterns, MIT.

A set of patterns for handing responsibility for production support from one on-call engineer to the next.

In plain words
What is it for?
Use it to write shift summaries, transfer active investigations, document workarounds, define escalation procedures, and onboard incoming on-call engineers.
Why use it?
It prevents important incident details, investigations, recent changes, and upcoming risks from being lost during a shift change.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

on-call-handoff-patterns scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

88% identical to on-call-handoff-patterns — 13 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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

## 🟡 Ongoing Investigations

### 1. Intermittent API Timeouts (ENG-1234)
**Status**: Investigating
**Started**: 2024-01-20
**Impact**: ~0.1% of requests timing out

**Context**:
- Timeouts correlate with database backup window (02:00-03:00 UTC)
- Suspect backup process causing lock contention
- Added extra logging in PR #567 (deployed 01/21)

**Next Steps**:
- [ ] Review new logs after tonight's backup
- [ ] Consider moving backup window if confirmed

**Resources**:
- Dashboard: [API Latency](https://grafana/d/api-latency)
- Thread: #platform-eng (01/20, 14:32)

---

### 2. Memory Growth in Auth Service (ENG-1235)
**Status**: Monitoring
**Started**: 2024-01-18
**Impact**: None yet (proactive)

**Context**:
- Memory usage growing ~5% per day
- No memory leak found in profiling
- Suspect connection pool not releasing properly

**Next Steps**:
- [ ] Review heap dump from 01/21
- [ ] Consider restart if usage > 80%

**Resources**:
- Dashboard: [Auth Service Memory](https://grafana/d/auth-memory)
- Analysis doc: [Memory Investigation](https://docs/eng-1235)

## 🟢 Resolved This Shift

### Payment Service Outage (2024-01-19)
- **Duration**: 23 minutes
- **Root Cause**: Database connection exhaustion
- **Resolution**: Rolled back v2.3.4, increased pool size
- **Postmortem**: [POSTMORTEM-89](https://docs/postmortem-89)
- **Follow-up tickets**: ENG-1230, ENG-1231

**Ticket**: OPS-456 (P3)

### 2. Flaky Integration Test
**Issue**: `test_payment_flow` fails intermittently in CI
**Workaround**: Re-run failed job (usually passes on retry)
**Ticket**: ENG-1200 (P2)
