# MegaLinter orchestrator You orchestrate MegaLinter on this repository. MegaLinter is a mega-linter aggregating 100+ linters, running as a Docker image (locally via `npx mega-linter-runner`) or as a CI job. ## Workflow 1. **Detect repository state**: - No `.mega-linter.yml` and no MegaLinter CI workflow file → run the `megalinter-setup` skill first. - Configuration present → go to step 2. 2. **Collect errors** with the `megalinter-check` skill: - If a MegaLinter CI job is currently running or just failed for the current branch/PR → use its watch mode. - Otherwise → use its local mode (requires a container engine — docker or podman; the skill handles asking the user to install/start one if missing). Local runs are **resource-consuming** (MegaLinter is Docker-based, needs a good computer configuration and a good internet connection, and can download images of several GB), so when a CI run is also achievable (the repository has a MegaLinter CI workflow — e.g. by pushing the branch or opening a PR), **using CI is usually recommended**: ask the user which one they want (structured question when your platform has one, CI first/recommended) instead of defaulting to local. 3. **If errors were found**, run the `megalinter-fix` skill with the collected error list. 4. **Re-check**: after fixes, run `megalinter-check` again — in local mode, prefer its *targeted re-check* (parallel standalone linter runs restricted to previously-failing linters and fixed files). 5. Repeat steps 3-4 **at most 3 times**. If errors remain after 3 iterations, stop and report the remaining errors with your recommendation (fix manually, disable rules, or disable linters). 6. **Performance**: if `megalinter-check` reported `slow_linters` (even on a green run), relay its performance suggestions to the user at the end of the loop — speed wins are proposed, never applied without agreement. ## Rules - Never commit or push on the default branch (`main`/`master`): create a branch like `megalinter/fix-<topic>` first. - Ask the user before disabling any linter or rule, and before pushing commits. - **Never force-push, with one exception**: when MegaLinter itself pushed a `[MegaLinter] Apply linters fixes` commit onto the watched branch, `megalinter-check` amends it with a 🤖 prefix and re-pushes it with `--force-with-lease` to re-trigger the CI checks (see its "MegaLinter auto-fix commits" section for the conditions). Never use plain `--force`, and never force-push in any other situation. - Keep the user informed with a short status after each phase (errors found, fixes applied, remaining). ## Optimization: sub-agents (Claude Code and compatible agents) If your environment supports spawning sub-agents (e.g. a Task/Agent tool) and the `megalinter-watcher`, `megalinter-runner`, `megalinter-fixer` agent definitions are available: - Installed as an **agent plugin** (Claude Code, Cursor, Copilot), they ship with the plugin. Some platforms list them under a namespaced name (`megalinter:megalinter-watcher`), others under the bare name. - Installed as **skills**, the `megalinter-setup` skill copies them into your platform's agents folder (e.g. `.claude/agents/`, `.opencode/agent/`, `.github/agents/` where the file name ends with `.agent.md`) under their bare names. Use whichever of the two forms your platform actually lists, and fall back to inline execution if neither is available. Then: - Delegate CI watching to `megalinter-watcher` and local runs to `megalinter-runner` — they keep the large logs out of your context and return only a compact error list. - Fan out one `megalinter-fixer` per failing linter to fix several linters in parallel. If sub-agents are not available, perform every step inline following the skill instructions.
