# AGENTS.md — how changes are made in this repo

This file is read by AI agents (via opencode) **and** by human developers. Follow it.

## What this repo is
The public **homepage** served at `homepage.ffaerber.duckdns.org`. The site is built into a **Docker
image**, pushed to this Gitea instance's **container registry**, and deployed via the homelab stack
(`ffaerber/homelab`). This repo holds the website source and its `Dockerfile`/build; it does **not**
hold the deployment stack itself.

## Golden rules
- You may edit **any file** in this repo (site source, `Dockerfile`, `.gitea/` workflows).
- **NEVER push to `main`, and NEVER merge a pull request.** All work goes on a branch and becomes a
  PR that a human reviews and merges. You do not have merge authority — do not attempt it.
- **Never print, exfiltrate, or invent secret values.** You may edit config that *references* secrets,
  but never paste real secret values into comments, PRs, logs, or code.
- Keep changes **minimal** and match the conventions already in the file you're editing.
- Do the work on a **branch** — never paste code or diffs into the issue thread.
- The repo is **public** and the built image is public, so it can be pulled without registry
  credentials. Do not add anything secret to the image or the source.

## Branches & pull requests
You start on branch `ai/issue-<N>` (N = the issue number).

**Split independent changes into separate PRs** so each can be reviewed and shipped on its own. For
each independent change, use its own branch:

```
git checkout main
git checkout -b ai/issue-<N>-<short-slug>      # e.g. ai/issue-3-nav, ai/issue-3-styles
# make just that one change
git add -A && git commit -m "<what changed>" && git push -u origin HEAD
```

- Only keep changes together on one branch if they genuinely must ship as a unit.
- Commit and **push incrementally** as you work, so progress is visible on the branch.
- **Do not open pull requests yourself** — the automation opens one PR per branch you push, and
  the maintainer merges them sequentially.

## PR description
End your reply with a clean pull-request description wrapped EXACTLY between these markers.
Everything before `BEGIN_PR_DESCRIPTION` is treated as working notes and discarded:

```
BEGIN_PR_DESCRIPTION
## Summary
<1-2 sentences: what changed and why>
## Changes
<short bullet list of the changes>
END_PR_DESCRIPTION
```

Do not paste full files or large diffs — the review happens in the PR diff.

## Build & deploy
- The site is packaged by a `Dockerfile` at the repo root (add one when the site source lands).
- On merge to `main`, CI builds the image and pushes it to the Gitea container registry; the
  homelab stack then pulls and serves it at `homepage.ffaerber.duckdns.org`.
- Keep the image small and the build reproducible. Prefer a static-site build served by a minimal
  web server (e.g. nginx) unless an issue says otherwise.

## When unsure
If the task is genuinely unclear or missing details you cannot reasonably assume, make **no**
changes and reply with specific questions instead.
