chain-patterns

Chain patterns for multi-phase pipelines: MCP detection, handoff files, checkpoint-resume, worktree agents, CronCreate monitoring. Use when building or debugging a pipeline skill.

doctor

OrchestKit doctor for health diagnostics across manifest integrity, hook configuration, skill validation, agent frontmatter, MCP server connectivity, CC version compatibility, and permission rules. Reports issues with severity levels and auto-remediation suggestions. Validates component counts, detects orphaned entries, and checks CC version matrix compliance. Use when diagnosing plugin health, troubleshooting configuration issues, or running pre-release checks.

telemetry-inspect

Inspects the OrchestKit telemetry pipeline for the current project — lists all known telemetry files with write counts, sizes, schema status, growth trend, and orphan detection. Use when verifying the observability pipeline is healthy, debugging a missing writer, or auditing which files have schema locks vs. which are drift-vulnerable. Read-only — never modifies telemetry files.

Stress	10-20 min	2-3x expected	Find breaking point	Pre-launch
Spike	5 min	Sudden 10x surge	Test auto-scaling	Before events
Soak	4-12 hours	Normal load	Detect memory leaks	Weekly/nightly

Metric	Target	Tool
p95 response time	< 500ms	k6
p99 response time	< 1000ms	k6
Error rate	< 1%	k6 / Locust
Business logic coverage	90%	pytest-cov
Critical path coverage	100%	pytest-cov

Scenario	Recommendation
JavaScript/TypeScript team	k6 for load testing
Python team	Locust for load testing
Need CI thresholds	k6 (built-in threshold support)
Need distributed testing	Locust (built-in distributed mode)
Slow test suite	pytest-xdist with `-n auto`
Flaky parallel tests	`--dist loadscope` for fixture grouping
DB-heavy tests	Worker-isolated databases with `worker_id`
