CircleCI-Public

Enable CircleCI Smarter Testing features (test impact analysis, dynamic test splitting, auto-rerun failed tests) on top of an existing testsuite, driven by `circleci testsuite doctor`. Use for test impact analysis, dynamic test splitting, auto-rerun, or…

Onboard a project onto CircleCI's testsuite (`.circleci/test-suites.yml` + `circleci testsuite run`), or migrate off legacy `circleci tests split`/raw test commands onto it. Initial setup for smarter testing features. Driven entirely by `circleci testsuite…

Day-to-day CircleCI from the terminal with the circleci CLI — authenticate, validate config before you commit, watch the run your push triggered, review pipeline/workflow/job status, read job logs and failed tests, download artifacts, and…

Agent-driven onboarding guide for CircleCI. Walks a user through the full setup journey: account creation, org setup, GitHub App connection, project creation, pipeline definition + trigger, and iterating a config file until it passes. Use this skill whenever…

Diagnose and fix failing CircleCI builds quickly and safely. Use when users ask to investigate failed CircleCI jobs, triage flaky pipelines, identify root causes from logs, and implement minimal fixes in configuration, test setup, or build-related code paths.

Optimize CircleCI configuration for speed, reliability, and maintainability. Use when users ask to improve `.circleci/config.yml`, reduce CI runtime, tune caching/workspaces/parallelism, remove pipeline waste, or fix flaky pipeline behavior caused by…

Use when the user says "set up chunk sidecar", "onboard to chunk", "first time sidecar", "configure sidecar from scratch", "walk me through sidecar setup", "set up smarter testing from scratch", "sidecar onboarding", "new sidecar environment", or "I've never…

Use when the user says "validate on the sidecar", "run tests on the sidecar", "sync to sidecar", "sidecar dev loop", "check this on the sidecar", "validate remotely", "scaffold test-suites.yml", "set up smarter testing", "write .circleci/test-suites.yml",…

Use when asked to "find testing gaps", "chunk testing-gaps", "mutation test", "mutate this code", "test mutation coverage", or "find surviving mutants". Runs a 4-stage mutation testing process: discovery, validation on parallel sidecars, production…

Use when asked to "review recent changes", "chunk review", "review my diff", "review this PR", "review PR

Debug CircleCI build failures, analyze test results, and identify flaky tests. Use when the user says "debug CI", "why is CI failing", "fix CI failures", "find flaky tests", "what broke in CI", "check CircleCI", or asks about failing pipelines or build errors.

Patterns for invoking the CircleCI CLI (circle) from agents. Covers structured output, project and org targeting, list, circleci api fallback.
