+description: Create a Gitea pull request, monitor CI pipeline status, and merge when green. Use this skill when the user asks to "create a PR", "merge the PR", "ship it", "make it ready to merge", or when you need to open a pull request and wait for CI before merging. Also use when asked to check CI/PR status on Gitea.
+---
+
+# Merge PR
+
+Create a pull request on Gitea, monitor the CI pipeline via the Actions API, and merge once all jobs pass.
+
+## Why this skill exists
+
+The Gitea MCP pull request API does not return CI status directly. To know if a PR is ready to merge, you must cross-reference the PR's `head.sha` with the Actions runs API, find the matching run, and check job conclusions. This skill encodes that workflow so it doesn't have to be rediscovered.
+
+## Prerequisites
+
+The Gitea MCP tools must be available. The key tools are:
+
+- `mcp__gitea__pull_request_write` (method: `create`, `merge`)
+- `mcp__gitea__pull_request_read` (method: `get`)
+- `mcp__gitea__actions_run_read` (methods: `list_runs`, `list_run_jobs`)
+
+If these tools are not yet loaded, use ToolSearch to discover and load them before proceeding.
+
+## Workflow
+
+### 1. Create the PR
+
+Use `mcp__gitea__pull_request_write` with method `create`. Include a clear title, body with summary and test plan, head branch, and base branch (usually `master`).
+
+Save the returned `head.sha` — you need it to find the CI run.
+
+### 2. Find the CI run for the PR
+
+The Actions API has no direct "get CI status for PR" call. Instead:
+
+```
+mcp__gitea__actions_run_read(method: "list_runs", owner, repo, perPage: 5)
+```
+
+Find the run whose `head_sha` matches the PR's `head.sha`. This is the CI run triggered by the push that the PR points to. If the branch was force-pushed or new commits were added, always match against the latest `head.sha` from a fresh `get` on the PR.
+
+### 3. Monitor job status
+
+Once you have the run ID:
+
+```
+mcp__gitea__actions_run_read(method: "list_run_jobs", owner, repo, run_id: <id>)
+```
+
+This returns all jobs with their `status` (queued/in_progress/completed) and `conclusion` (success/failure/skipped/null).
+
+Present a status table to the user:
+
+| Job | Status |
+|-----|--------|
+| backend-test | success |
+| frontend-test | in_progress |
+| frontend-e2e | queued |
+
+If jobs are still running, wait ~30 seconds and check again. Don't poll in a tight loop.
+
+### 4. Handle failures
+
+If any job has `conclusion: failure`:
+- Use `mcp__gitea__actions_run_read` with method `get_job_log_preview` to fetch the failing job's log
+- Report the failure to the user with relevant log output
+- Do NOT attempt to merge
+
+### 5. Merge when green
+
+Once all jobs show `conclusion: success` (or `skipped` for conditional jobs like `build-and-publish`):
+
+```
+mcp__gitea__pull_request_write(
+  method: "merge",
+  owner, repo,
+  index: <pr_number>,
+  merge_style: "merge",
+  delete_branch: true
+)
+```
+
+Ask the user for confirmation before merging. They may want to review the PR in the web UI first.
+
+### 6. Post-merge cleanup
+
+After a successful merge, suggest:
+- `git checkout master && git pull origin master`
+- `git branch -d <feature-branch>` (local cleanup)
+- Tagging a release if appropriate (see `/release` skill)
+
+## Abbreviated flow
+
+When the user just wants a quick status check (e.g. "how's the PR?"), skip straight to steps 2-3: find the run by SHA, show the job status table.

+## Nicht umgesetzte Feature-Ideen (ehemals Specs 009–026)
+
+### 009 – Gästeliste
+Organisator sieht alle RSVPs (Name, Status) und kann einzelne Einträge löschen.
+* Nur mit gültigem Organizer-Token sichtbar
+* Gäste ohne Token sehen keine Gästeliste
+* Löschung serverseitig validiert
+
+### 010 – Event bearbeiten
+Organisator kann Titel, Beschreibung, Datum, Ort und Ablaufdatum ändern.
+* Formular vorausgefüllt mit aktuellen Werten
+* Ablaufdatum muss in der Zukunft liegen
+* Ohne Organizer-Token kein Edit-UI sichtbar
+
+### 011 – Event merken/bookmarken
+Gäste können Events lokal merken, ohne RSVP abzugeben — rein clientseitig via localStorage.
+* Kein Serverkontakt nötig
+* Unabhängig vom RSVP-Status
+* Auch bei abgelaufenen Events möglich
+
+### 012 – Lokale Event-Übersicht
+Startseite (`/`) zeigt alle getrackten Events (erstellt, zugesagt, gemerkt) aus localStorage.
+* Zeigt Titel, Datum, Beziehungstyp (Organisator/Gast/Gemerkt)
+* Vergangene Events als "beendet" markiert
+* Einträge können entfernt werden
+
+### 013 – Kalender-Export
+.ics-Download (RFC 5545) mit Event-Details, optional webcal:// für Live-Updates.
+* Stabile UID aus Event-Token (Re-Import aktualisiert statt dupliziert)
+* Bei Absage: STATUS:CANCELLED im .ics
+* Kein externer Kalenderservice kontaktiert
+
+### 014 – Änderungen hervorheben
+Geänderte Felder werden visuell hervorgehoben, wenn der Gast seit der letzten Änderung nicht mehr auf der Seite war.
+* Server trackt `last_edited_at` + geänderte Feldnamen
+* Client speichert `last_seen_at` in localStorage
+* Privacy-freundlich: kein serverseitiges Read-Tracking
+
+### 015 – Organisator-Updates
+Organisator kann Textnachrichten im Event posten (Pinnwand-Stil).
+* Chronologisch sortiert, löschbar durch Organisator
+* Nach Ablauf kein Posting mehr möglich
+* Ohne Organizer-Token kein Compose-UI
+
+### 016 – Gast-Benachrichtigungen
+Badge/Indikator bei ungelesenen Organisator-Updates, rein clientseitig via localStorage.
+* Eigener Timestamp `updates_last_seen_at` (getrennt von Feld-Änderungen)
+* Kein Indikator beim ersten Besuch
+* Kein serverseitiges Tracking (Privacy)
+
+### 017 – QR-Code
+Event-Seite zeigt QR-Code mit der öffentlichen Event-URL.
+* Serverseitig generiert (kein externer QR-Service)
+* Download als SVG oder hochauflösendes PNG

+
+### 018 – Datenlöschung
+Automatische Löschung aller Event-Daten nach Ablaufdatum (Privacy-Garantie).
+* Scheduled Job oder Lazy Cleanup bei Zugriff
+* Löscht Event, RSVPs, Updates, Bilder, Metadaten
+* Idempotent, kein PII im Log
+
+### 019 – Instanz-Limit
+`MAX_ACTIVE_EVENTS` als Env-Variable begrenzt aktive Events für Self-Hoster.
+* Nur nicht-abgelaufene Events zählen
+* Unset/leer = unbegrenzt
+* Serverseitige Durchsetzung bei Event-Erstellung
+
+### 020 – PWA
+Web App Manifest + Service Worker für Installierbarkeit und Offline-Caching.
+* Standalone-Modus ohne Browser-Chrome
+* Icon + Name auf Home-Screen
+* Alle Assets selbstgehostet
+
+### 021 – Farbthemen
+Organisator wählt bei Erstellung ein vordefiniertes Farbthema für die Event-Seite.
+* Nur auf der Gast-Seite angewendet (nicht global)
+* Änderbar beim Bearbeiten

+Organisator löscht Event permanent und unwiderruflich.
+* Entfernt alle zugehörigen Daten sofort
+* localStorage-Eintrag wird entfernt, Redirect zu `/`
+* Funktioniert in jedem Event-Status
+
+### 026 – 404-Seite
+Catch-all Route für ungültige Pfade mit "Seite nicht gefunden" und Link zur Startseite.
+* Folgt dem Design System (Electric Dusk + Sora)
+* WCAG AA konform
+* Verhindert leere Seiten bei Fehlnavigation

+# Modern UI Effects Research (2025-2026)
+
+## Liquid Glass (Apple WWDC 2025)
+Evolved glassmorphism with directional lighting. Three-layer approach: highlight, shadow, illumination.
+- `backdrop-filter: blur(20px) saturate(1.5)` — higher saturation than basic glass
+- `inset 0 1px 0 rgba(255,255,255,0.15)` — top highlight (light direction)
+- `inset 0 -1px 0 rgba(0,0,0,0.1)` — bottom shadow
+- Outer drop shadow for depth: `0 8px 32px rgba(0,0,0,0.3)`
+- Advanced: SVG `feTurbulence` + `feSpecularLighting` for refraction (Chromium only)
+- Browser support: `backdrop-filter` ~88%, Firefox since v103
+
+## Aurora / Gradient Mesh Backgrounds
+Stacked animated radial gradients simulating northern lights. Pairs well with glass cards on dark backgrounds.
+- Multiple `radial-gradient(ellipse ...)` layers with partial opacity
+- Animated via `background-position` shift (GPU-friendly)
+- `@property` rule enables direct gradient color animation (broad support since 2024)
+- Best for ambient background movement, not for content areas
+
+## Animated Glow Borders
+Rotating `conic-gradient` borders with blur halo. Striking on dark backgrounds.
+- Outer wrapper with `conic-gradient(from var(--angle), color1, color2, color3, color1)`
+- `::before` pseudo with `filter: blur(12px)` and `opacity: 0.5` for glow halo
+- `@property --angle` trick to animate custom property inside `conic-gradient`
+- Use sparingly — best for single highlight elements (FAB, CTA), not all cards
+
+## Modern Neumorphism (2025-2026 revision)
+Subtler than the original trend. Higher contrast, less extreme extrusion, combined with accent colors.
+- Light and dark shadow pair: `6px 6px 12px rgba(0,0,0,0.5)` + `-6px -6px 12px rgba(60,50,80,0.15)`
+- `border: 1px solid rgba(255,255,255,0.05)` for definition
+- Works on dark backgrounds with slightly lighter "uplift" shadow direction
+- Better suited for interactive elements (buttons, toggles) than content cards
