+# AGENTS.md
+
+Guidance for AI coding assistants working in `fluxcd/flux2`. Read this file before making changes.
+
+## Contribution workflow for AI agents
+
+These rules come from [`fluxcd/flux2/CONTRIBUTING.md`](https://github.com/fluxcd/flux2/blob/main/CONTRIBUTING.md) and apply to every Flux repository.
+
+- **Do not add `Signed-off-by` or `Co-authored-by` trailers with your agent name.** Only a human can legally certify the DCO.
+- **Disclose AI assistance** with an `Assisted-by` trailer naming your agent and model:
+  ```sh
+  git commit -s -m "Add support for X" --trailer "Assisted-by: <agent-name>/<model-id>"
+  ```
+  The `-s` flag adds the human's `Signed-off-by` from their git config — do not remove it.
+- **Commit message format:** Subject in imperative mood ("Add feature X" instead of "Adding feature X"), capitalized, no trailing period, ≤50 characters. Body wrapped at 72 columns, explaining what and why. No `@mentions` or `#123` issue references in the commit — put those in the PR description.
+- **Trim verbiage:** in PR descriptions, commit messages, and code comments. No marketing prose, no restating the diff, no emojis.
+- **Rebase, don't merge:** Never merge `main` into the feature branch; rebase onto the latest `main` and push with `--force-with-lease`. Squash before merge when asked.
+- **Pre-PR gate:** `make tidy fmt vet && make test` must pass and the working tree must be clean.
+- **Flux is GA:** Backward compatibility is mandatory. Breaking changes to CLI flags, output format, or behavior will be rejected. Design additive changes.
+- **Copyright:** All new `.go` files must begin with the header from `cmd/flux/main.go` (Apache 2.0). Update the year to the current year when copying.
+- **Tests:** New features, improvements and fixes must have test coverage. Add unit tests in `cmd/flux/*_test.go` tagged `//go:build unit`. Follow the existing `cmdTestCase` + golden file patterns. Run tests locally before pushing.
+
+## Code quality
+
+Before submitting code, review your changes for the following:
+
+- **No secrets in logs or output.** Never surface auth tokens, passwords, deploy keys, or credential URLs in error messages, log lines, or CLI output. Bootstrap and source-secret commands handle sensitive material — take extra care.
+- **No unchecked I/O.** Close HTTP response bodies, file handles, and tar readers in `defer` statements. Check and propagate errors from I/O operations.
+- **No path traversal.** Validate and sanitize file paths extracted from archives or user input. Never `filepath.Join` with untrusted components without validation.
+- **No command injection.** Do not shell out via `os/exec` for git, helm, or kustomize operations. Use the Go libraries already in use (`fluxcd/pkg/git`, `fluxcd/pkg/kustomize`, `fluxcd/pkg/ssa`).
+- **No hardcoded defaults for security settings.** TLS verification must remain enabled by default. Git auth settings come from user-provided secrets.
+- **Error handling.** Wrap errors with `%w` for chain inspection. Do not swallow errors silently. CLI errors must be actionable — tell the user what went wrong and how to fix it without leaking internal state.
+- **Resource cleanup.** Ensure temporary files and directories (manifest staging, downloaded tarballs) are cleaned up on all code paths (success and error). Use `defer` and `t.TempDir()` in tests.
+- **No panics.** Never use `panic` in runtime code paths. Return errors and let the CLI handle them gracefully.
+- **Output discipline.** Machine-readable data (tables, YAML, JSON) goes to stdout via `rootCmd.OutOrStdout()`. Human-readable status messages go to stderr via the `stderrLogger`.
+- **Minimal surface.** Keep new exported APIs in `pkg/` to the minimum needed. Every export is a backward-compatibility commitment.
+
+## Project overview
+
+flux2 is the Flux CLI (`flux` command) and distribution repository. It is **not** a controller — it consumes CRD APIs from six independent controller repos (source-controller, kustomize-controller, helm-controller, notification-controller, image-reflector-controller, image-automation-controller). It serves two purposes:
+
+1. **CLI tool** — a Cobra-based binary that installs Flux onto Kubernetes clusters, bootstraps GitOps pipelines, and manages all Flux CRD objects (create, get, export, reconcile, suspend, resume, delete, diff, build, etc.).
+2. **Distribution hub** — it bundles the Kustomize manifests for all Flux controllers and releases them as `manifests.tar.gz` on GitHub. Those manifests are also compiled into the binary itself via `//go:embed`.
+
+## Repository layout
+
+- `cmd/flux/` — all CLI source. Single `main` package with one file per command or resource type. `main.go` defines the root cobra command with global flags. `manifests.embed.go` embeds the generated controller manifests via `//go:embed`.
+- `internal/build/` — `flux build kustomization` logic (kustomize-based diff/build, SOPS secret masking).
+- `internal/flags/` — custom `pflag.Value` types providing enum validation (e.g. `LogLevel`, `ECDSACurve`, `RSAKeyBits`, `PublicKeyAlgorithm`, `DecryptionProvider`).
+- `internal/tree/` — tree-printing helper for `flux tree kustomization`.
+- `internal/utils/` — shared helpers: `KubeClient`, `KubeConfig`, `NewScheme` (registers all controller API groups), `Apply` (SSA-based two-phase apply), `ExecKubectlCommand`, `ValidateComponents`.
+- `pkg/bootstrap/` — bootstrap orchestration: `Run()`, `PlainGitBootstrapper`, `ProviderBootstrapper`. `provider/` has the git provider factory (GitHub, GitLab, Gitea, Bitbucket).
+- `pkg/log/` — `Logger` interface (`Actionf`, `Generatef`, `Waitingf`, `Successf`, `Warningf`, `Failuref`).
+- `pkg/manifestgen/` — manifest generation for install, sync, kustomization, and source secrets.
+- `pkg/printers/` — specialized printers `TablePrinter` and `DyffPrinter`.
+- `pkg/status/` — `StatusChecker` using `fluxcd/cli-utils` kstatus polling.
+- `pkg/uninstall/` — `flux uninstall` logic.
+- `manifests/` — Kustomize bases per controller, RBAC, network policies, CRD references, and `scripts/bundle.sh` which runs `kustomize build` to generate `cmd/flux/manifests/`.
+- `tests/integration/` — cloud e2e tests (Azure/GCP) with their own `go.mod` and Terraform infrastructure.
+- `rfcs/` — Request for Comments documents for major design proposals and changes.
+
+## CLI architecture
+
+Commands are Cobra-based, organized as parent + per-resource children:
+- Group files (`create.go`, `get.go`, `reconcile.go`, etc.) register the parent subcommand.
+- Per-resource files (`create_kustomization.go`, `get_helmrelease.go`, etc.) register children.
+
+Core interfaces in `cmd/flux/` enable generic command implementations:
+- `adapter` / `copyable` / `listAdapter` — wrap controller API types for generic CRUD.
+- `reconcilable` — annotate-and-poll pattern for triggering reconciliation.
+- `summarisable` — generic table output for `get` commands.
+
+Each resource type (e.g. `kustomizationAdapter` in `kustomization.go`) wraps the controller API type and implements these interfaces. Follow this pattern when adding new resource support.
+
+Commands interact with the Kubernetes API via `internal/utils.KubeClient()` → `client.WithWatch`. `internal/utils.NewScheme()` registers all six controller API groups plus core k8s types. `internal/utils.Apply()` implements SSA-based two-phase apply (CRDs/Namespaces first, then remaining objects).
+
+## Manifest pipeline
+
+1. `manifests/bases/<controller>/` contains a Kustomize base per controller referencing the controller's GitHub release for CRDs and deployment manifests.
+2. `manifests/install/kustomization.yaml` assembles all bases plus RBAC and policies.
+3. `manifests/scripts/bundle.sh` runs `kustomize build` on each base, writing output to `cmd/flux/manifests/` (not checked in — generated).
+4. The Makefile `$(EMBEDDED_MANIFESTS_TARGET)` runs `bundle.sh` and creates a sentinel file `cmd/flux/.manifests.done`.
+5. `cmd/flux/manifests.embed.go` uses `//go:embed manifests/*.yaml` to compile everything into the binary.
+
+When modifying `manifests/`, always run `make build` and verify the generated output before committing. Never hand-edit files under `cmd/flux/manifests/`.
+
+## Build, test, lint
+
+All targets in the root `Makefile`. Go version tracks `go.mod`.
+
+- `make tidy` — tidy the root module and `tests/integration/`.
+- `make fmt` / `make vet` — run in the root module.
+- `make build` — builds `bin/flux` (CGO disabled, version injected via ldflags). Depends on embedded manifests being generated.
+- `make build-dev` — builds with `DEV_VERSION`.
+- `make install` / `make install-dev` — `go install` or copy to `/usr/local/bin`.
+- `make test` — unit tests with envtest: runs `tidy fmt vet install-envtest`, then `go test ./... -coverprofile cover.out --tags=unit $(TEST_ARGS)`.
+- `make e2e` — e2e tests against a live cluster: `go test ./cmd/flux/... --tags=e2e -v -failfast`.
+- `make test-with-kind` — sets up a kind cluster, runs e2e, tears it down.
+- `make install-envtest` — downloads `setup-envtest` and fetches k8s binaries into `testbin/`.
+
+Run a single test: `make test TEST_ARGS='-run TestCreate -v'`.
+
+## Codegen and generated files
+
+Check `go.mod` and the `Makefile` for current dependency and tool versions. The main codegen pipeline is the manifest bundle:
+
+```sh
+./manifests/scripts/bundle.sh
+```
+
+Generated files (never hand-edit):
+
+- `cmd/flux/manifests/*.yaml` — generated by `bundle.sh` from `manifests/` sources.
+- `cmd/flux/.manifests.done` — sentinel file tracking bundle state.
+
+Bump `fluxcd/pkg/*` and controller `api` modules as a set. Run `make tidy` after any bump.
+
+## Conventions
+
+- Standard `gofmt`. All exported names need doc comments.
+- **Command pattern:** follow the existing group-parent + per-resource-child cobra structure. New resources need an adapter type implementing `adapter`, `copyable`, and the relevant command interfaces (`reconcilable`, `summarisable`, etc.).
+- **Output:** stderr for human status messages via `stderrLogger` (Unicode symbols: `►` action, `✔` success, `✗` failure, `◎` waiting, `⚠️` warning, `✚` generate). Stdout for machine-readable data (tables, YAML, JSON) via `rootCmd.OutOrStdout()`.
+- **Global flags:** kubeconfig flags come from `k8s.io/cli-runtime/pkg/genericclioptions.ConfigFlags`. Client tuning comes from `fluxcd/pkg/runtime/client.Options`. `FLUX_SYSTEM_NAMESPACE` env var overrides the default namespace.
+- **SSA apply:** always use `internal/utils.Apply()` (two-phase: CRDs/Namespaces first, then rest). Do not apply manifests directly via the k8s client.
+- **Reconcile triggering:** patch `meta.ReconcileRequestAnnotation` with a timestamp, then poll with `kstatus.Compute()` until ready. See `reconcile.go`.
+- **Error handling:** return errors from `RunE`. Use `*RequestError` with exit codes for actionable CLI errors. Exit code 1 = warning, anything else = failure.
+- **Flags:** use `internal/flags/` custom `pflag.Value` types for enum flags (providers, algorithms, sources). Add new enum types there.
+
+## Testing
+
+Three test suites with build tags:
+
+- **Unit** (`//go:build unit`): lives in `cmd/flux/*_test.go`. Uses `controller-runtime/envtest` for an in-process fake k8s API. CRDs are loaded from `cmd/flux/manifests/` (embedded manifests). Pattern: `cmdTestCase{args: "...", assert: assertGoldenFile("testdata/...")}`. The `executeCommand()` helper captures stdout.
+- **E2e** (`//go:build e2e`): lives in `cmd/flux/*_test.go`. Requires a live cluster via `TEST_KUBECONFIG`. `TestMain` runs `flux install` for setup and teardown.
+- **Integration** (`//go:build integration`): lives in `tests/integration/` with its own `go.mod`. Uses Terraform-provisioned cloud clusters.
+
+Golden files live in `cmd/flux/testdata/`. Update them with `go test ./cmd/flux/... --tags=unit -update`.
+
+Run a single unit test: `make test TEST_ARGS='-run TestInstall -v'`.
+
+## Gotchas and non-obvious rules
+
+- The `cmd/flux/manifests/` directory is **generated, not checked in**. It is created by `manifests/scripts/bundle.sh` and embedded into the binary. `make build` and `make test` both trigger the bundle if the sentinel file is stale.
+- `kustomize` must be on `PATH` for `bundle.sh` to work. If you see "command not found" errors during build, install kustomize.
+- `internal/utils.NewScheme()` registers all six controller API groups. Adding support for a new CRD type means updating the scheme registration there.
+- The `VERSION` constant is injected via `-ldflags` at build time. In dev builds it defaults to `0.0.0-dev.0`. The embedded manifest version check (`isEmbeddedVersion`) determines whether `flux install` uses compiled-in manifests or downloads from GitHub.
+- `resetCmdArgs()` in tests is critical — Cobra persists flag state between test runs. Every test case must reset to avoid pollution.
+- `executeCommand()` captures stdout only. Stderr output (from `stderrLogger`) is not captured in test assertions. If your command's output goes to the wrong stream, tests will silently pass with empty golden files.
+- The `adapter` / `listAdapter` interfaces use type assertions internally. If you add a new resource type and forget to implement an interface method, you'll get a runtime panic in the generic command handler, not a compile error. Add interface compliance checks (`var _ reconcilable = ...`).
+- Bootstrap commands create real Git commits and push to real repos. E2e tests for bootstrap need careful cleanup. Do not add bootstrap e2e tests without a corresponding teardown.
+- `pkg/` packages are importable by external consumers (e.g. Terraform provider, other tools). Treat their exported surface as public API.

-## Understanding Flux and the GitOps Toolkit
-
-If you are entirely new to Flux and the GitOps Toolkit,
-you might want to take a look at the [introductory talk and demo](https://www.youtube.com/watch?v=qQBtSkgl7tI).
-
-This project is composed of:
-
-- [flux2](https://github.com/fluxcd/flux2): The Flux CLI
-- [source-manager](https://github.com/fluxcd/source-controller): Kubernetes operator for managing sources (Git and Helm repositories, S3-compatible Buckets)
-- [kustomize-controller](https://github.com/fluxcd/kustomize-controller): Kubernetes operator for building GitOps pipelines with Kustomize
-- [helm-controller](https://github.com/fluxcd/helm-controller): Kubernetes operator for building GitOps pipelines with Helm
-- [notification-controller](https://github.com/fluxcd/notification-controller): Kubernetes operator for handling inbound and outbound events
-- [image-reflector-controller](https://github.com/fluxcd/image-reflector-controller): Kubernetes operator for scanning container registries
-- [image-automation-controller](https://github.com/fluxcd/image-automation-controller): Kubernetes operator for patches container image tags in Git
-
-### Understanding the code
-
-To get started with developing controllers, you might want to review
-[our guide](https://fluxcd.io/flux/gitops-toolkit/source-watcher/) which
-walks you through writing a short and concise controller that watches out
-for source changes.
-
-## How to run the test suite
-
-Prerequisites:
-
-* go >= 1.24
-* kubectl >= 1.30
-* kustomize >= 5.0
-* coreutils (on Mac OS)
-
-Install the [controller-runtime/envtest](https://github.com/kubernetes-sigs/controller-runtime/tree/master/tools/setup-envtest) binaries with:
-
-```bash
-make install-envtest
-```
-
-Then you can run the unit tests with:
-
-```bash
-make test
-```
-
-After [installing Kubernetes kind](https://kind.sigs.k8s.io/docs/user/quick-start#installation) on your machine,
-create a cluster for testing with:
-
-```bash
-make setup-kind
-```
-
-Then you can run the end-to-end tests with:
-
-```bash
-make e2e
-```
-
-When the output of the Flux CLI changes, to automatically update the golden
-files used in the test, pass `-update` flag to the test as:
-
-```bash
-make e2e TEST_ARGS="-update"
-```
-
-Since not all packages use golden files for testing, `-update` argument must be
-passed only for the packages that use golden files. Use the variables
-`TEST_PKG_PATH` for unit tests and `E2E_TEST_PKG_PATH` for e2e tests, to set the
-path of the target test package:
-
-```bash
-# Unit test
-make test TEST_PKG_PATH="./cmd/flux" TEST_ARGS="-update"
-# e2e test
-make e2e E2E_TEST_PKG_PATH="./cmd/flux" TEST_ARGS="-update"
-```
-
-Teardown the e2e environment with:
-
-```bash
-make cleanup-kind
-```
-
 ## Acceptance policy
 
 These things will make a PR more likely to be accepted:
 
-- a well-described requirement
-- tests for new code
-- tests for old code!
-- new code and tests follow the conventions in old code and tests
-- a good commit message (see below)
-- all code must abide [Go Code Review Comments](https://github.com/golang/go/wiki/CodeReviewComments)
-- names should abide [What's in a name](https://talks.golang.org/2014/names.slide#1)
-- code must build on both Linux and Darwin, via plain `go build`
-- code should have appropriate test coverage and tests should be written
-  to work with `go test`
+- Addressing an open issue, if one doesn't exist, please open an issue to discuss the problem and the proposed solution before submitting a PR.
+- Flux is GA software and we are committed to maintaining backward compatibility. If your contribution introduces a breaking change, expect for your PR to be rejected.
+- New code and tests must follow the conventions in the existing code and tests. All new code must have good test coverage and be well documented.
+- All top-level Go code and exported names should have doc comments, as should non-trivial unexported type or function declarations.
+- Before submitting a PR, make sure that your code is properly formatted by running `make tidy fmt vet` and that all tests are passing by running `make test`.
 
 In general, we will merge a PR once one maintainer has endorsed it.
 For substantial changes, more people may become involved, and you might
 get asked to resubmit the PR or divide the changes into more than one PR.
 
-### Format of the Commit Message
+## Format of the Commit Message
 
-For the GitOps Toolkit controllers we prefer the following rules for good commit messages:
+For the Flux project we prefer the following rules:
 
-- Limit the subject to 50 characters and write as the continuation
-  of the sentence "If applied, this commit will ..."
-- Explain what and why in the body, if more than a trivial change;
-  wrap it at 72 characters.
+- Limit the subject to 50 characters, start with a capital letter and do not end with a period.
+- Explain what and why in the body, if more than a trivial change; wrap it at 72 characters.
+- Use the imperative mood in the subject line (e.g., "Add support for X" instead of "Added support for X" or "Adds support for X").
+- Do not include GitHub mentions to issues in the commit message, use the PR description instead (e.g., "Fixes #123" or "Closes #123").
+- Do not include GitHub mentions to accounts (e.g., `@username` or `@team`) within the commit message.
 
-The [following article](https://chris.beams.io/posts/git-commit/#seven-rules)
-has some more helpful advice on documenting your work.
+## Pull Request Process
+
+Fork the repository and create a new branch for your changes, do not commit directly to the `main` branch.
+Once you have made your changes and committed them, push your branch to your fork and open a pull request
+against the `main` branch of the Flux repository.
+
+During the review process, you may be asked to make changes to your PR. Add commits to address the feedback
+without force pushing, as this will make it easier for reviewers to see the changes.
+Before committing, make sure to run `make test` to ensure that your code will pass the CI checks.
+
+When the review process is complete, you will be asked to **squash** the commits and **rebase** your branch.
+**Do not merge** the `main` branch into your branch, instead, rebase your branch on top of the latest `main`
+branch after **syncing your fork** with the latest changes from the Flux repository. After rebasing,
+you can push your branch with the `--force-with-lease` option to update the PR.
+
