+# AGENTS.md
+
+This is **authentik** — an open-source Identity Provider. The codebase spans a
+Django backend, Go outposts, Rust components, and a Lit/TS web UI, with pieces
+wired together through Django signals, Channels, blueprints, flow plans, and a
+generated API client. It's a lot of moving parts. Before changing something
+non-trivial, pause to think about what else touches it: a model edit can ripple
+through serializers, signals, blueprints, and the generated TS client.
+
+## Commits
+
+Format the subject as `area: short message`. Skip the long body unless
+something genuinely needs explaining. The `area` is wherever you worked, e.g.:
+
+- `root:` — repo-wide changes
+- `core:` — `authentik/core` and dependency bumps
+- `api:` — API surface
+- `web:`, `web/admin:`, `web/flows:`, `web/stages:` — frontend
+- `website:`, `website/docs:`, `website/integrations:`
+- `stages/invitation:`, `providers/oauth2:`, `providers/oauth:` — feature modules
+- `enterprise/providers/ssf:`
+- `lifecycle/worker_process:`
+- `tenants:`, `ci:`, `docs:`, `translate:`
+
+When the user gives you a PR or issue for the bug being fixed, add a
+`Closes: #NNN` trailer on its own line — don't tack `(#NNN)` onto the subject.
+
+**Never** include customer information or any potentially sensitive *content*
+taken from internal sources — verbatim or reworded — anywhere in the repo
+(code, comments, commit messages, PR descriptions, docs) unless explicitly
+allowed. This covers customer names, support ticket contents, quoted Slack
+messages, private incident details, and similar.
+
+Links are fine. A Slack permalink, a GitHub issue link, or an internal ticket
+URL in a commit message or PR description is good context — it's the
+sensitive *content* that must not be copied into the repo. When in doubt,
+leave the content out and link instead.
+
+A commit should be a finished, working unit. Don't commit half-done work.
+Before committing, run whatever applies:
+
+- `make lint-fix`
+- `make gen` if you touched models or serializers
+- `make web` if you touched `web/`
+- `make docs` if you touched `website/docs/`
+- `make integrations` if you touched `website/integrations/`
+- `./manage.py makemigrations --check` — no pending migrations
+
+The `Makefile` has more targets per area (tests, Go, Rust) — use them when
+relevant.
+
+## Don't hand-edit generated or vendored files
+
+Run `make gen` instead. Off-limits:
+
+- `schema.yml` (OpenAPI)
+- `gen-ts-api/`
+- `packages/client-go/`, `packages/client-ts/`, `packages/client-rust/`
+- `schemas/` — these are upstream SAML / SCIM / WS-* specs, not ours
+
+If the output looks wrong, fix the source (models, serializers, generator
+config) and regenerate.
+
+## Migrations
+
+Generate them with `./manage.py makemigrations`. Don't hand-write or hand-edit
+migration files unless the user specifically asks (data migrations, squashes,
+or repairing a bad one). Read what Django produced before committing — autogen
+sometimes catches more than you intended.
+
+## Localization
+
+Anything user-visible needs to be translatable:
+
+- Python: `from django.utils.translation import gettext_lazy as _`, then `_("...")`
+- TS / Lit: `msg("...")` from `@lit/localize`
+- Django templates: `{% trans %}` / `{% blocktrans %}`
+
+No raw English strings in user-facing surfaces.
+
+## Tests, proportionate
+
+Size tests to the code. A 28-line function doesn't need a 400-line test file.
+Cover meaningful behavior and obvious edge cases; don't pad for coverage or
+re-test the framework. Mechanical changes (renames, type tweaks) usually ride
+on existing tests.
+
+## Reuse what's already there
+
+There's a large pool of helpers — find them before writing new ones.
+
+- **Django first.** `django.utils`, `django.shortcuts`, the ORM, the auth
+  framework — most generic things already exist there.
+- **Then authentik.** `authentik/lib/`, `authentik/core/`, and the feature
+  module you're working in.
+- **Call helpers, don't inline them.** If `plan.to_redirect()` exists, use it
+  instead of rebuilding the redirect at every call site. Same goes for
+  permission checks, flow plan helpers, event logging, serializer mixins, etc.
+
+## DRY, with judgment
+
+Deduplicate behavior, not boilerplate. Some things are cheap to restate and
+often clearer that way — serializers, simple model definitions, view glue,
+short config blocks — don't twist them through inheritance or shared bases
+just to save lines. But duplicated *behavior* — a function body copy-pasted
+across modules, a permission check reimplemented inline, a redirect built from
+scratch next to a helper that already does it — should collapse to one place.
+If changing the logic later would mean hunting down every copy, it belongs in
+one spot.
