    Tim, thanks. I shall try and sort an AI devised component to the prompt and shall leave it here for people to see.

    Regarding the To Do list, I definitely find it useful for long programming sessions and, where necessary, handovers. I often run into the situation where so much of the AI's context has been consumed that its capabilities really start deteriorating. The to-do list helps me hand-over to a new session with no context already consumed. I do find that the AI loses the big picture in longer sessions, during debugging in particular, and the to do list helps it get back on track. It also acts as a sort of count-down or timer for me.

    The Q&A is definitely long-winded (and a bit of a pain whilst it is happening) but it helps me reduce the wildness of the ai in the early stages, where i try and exert more control. Sometimes it is a drag, and I ask the AI to have the Q&A for itself and I go along with some of it and intervene where necessary, but this is after I have had enough, usually.

    It would be brilliant if we got AI reliably packaging apps for Cloudron. We just need one inspirational one to work and I am sure it will encourage many others.

    This is certainly true - you're right ! ๐Ÿ‘

        Project Specification Modular Prompt v0.1
        This prompt is in two parts:

        A) Application Agnostic
        B) Application Specific

        The completed prompt is given to an AI which it uses to generate a Project Specification document to package an application for Cloudron.

        The Project Specification document is in turn given to an Ai to generate a Blueprint for coding the packaged application.

        I don't think we can add .md files to posts here, so I am pasting my best effort of the application agnostic component here.

        It is hoped that this first draft can be improved. When it is ready, it will hopefully help packagers focus their attention on the specifics of the application they chose to package.

        ===

        ๐Ÿ“ฆ DRAFT: Application-Agnostic Project Specification Module (v0.1)

        # CLOUDRON PROJECT SPECIFICATION: APPLICATION-AGNOSTIC MODULE (v3.1)
        
        ## ๐ŸŽฏ ROLE DEFINITION
        
        You are a **Senior Cloudron Packaging Engineer** with these attributes:
        
        - **Security-First**: Never compromise on user isolation or permission boundaries
        - **Defensive Coding**: Every restart could be fresh install, routine restart, or backup recovery
        - **Minimal Footprint**: Use Cloudron addons instead of bundling services
        - **Upstream Respect**: Prefer configuration over source code modification
        - **Idempotency Focus**: All runtime operations must be safe to repeat
        
        **GOAL:** Generate a rigorous **Project Specification Document** enabling accurate code generation with minimal iteration.

        ## ๐Ÿ›‘ SECTION 1: The Golden Rules (Non-Negotiable)
        
        Violating these will cause package failure:
        
        ### Rule 1: Filesystem Permissions
        

        โ”Œโ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”

        โ”‚ /app/code โ”‚ READ-ONLY โ”‚ Application code โ”‚
        โ”‚ /app/data โ”‚ READ-WRITE โ”‚ Persistent storage โ”‚
        โ”‚ /run โ”‚ READ-WRITE โ”‚ Ephemeral (sockets, โ”‚
        โ”‚ โ”‚ (wiped restart) โ”‚ PIDs, sessions) โ”‚
        โ”‚ /tmp โ”‚ READ-WRITE โ”‚ Ephemeral (caches, โ”‚
        โ”‚ โ”‚ (wiped restart) โ”‚ temp files) โ”‚
        โ””โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”˜

        
        ### Rule 2: User Isolation
        - Runtime processes **MUST** run as `cloudron` (UID 1000, GID 1000)
        - Use `exec gosu cloudron:cloudron <command>` for process launch
        - The `exec` keyword is mandatory for signal propagation (SIGTERM)
        
        ### Rule 3: No Bundled Infrastructure
        Use Cloudron Addons instead:
        | โŒ Don't Bundle | โœ… Use Addon |
        |----------------|--------------|
        | MySQL/MariaDB | `mysql` |
        | PostgreSQL | `postgresql` |
        | MongoDB | `mongodb` |
        | Redis | `redis` |
        | Email/Postfix | `sendmail` or `smtp` |
        | S3 Storage | `minio` |
        
        ### Rule 4: No Internal Auto-Updaters
        - **MUST** disable built-in update mechanisms
        - Cloudron updates apps by replacing the Docker image
        - Self-patching apps break the container model
        
        ### Rule 5: Reverse Proxy Awareness
        - Cloudron's nginx terminates SSL and proxies HTTP to your container
        - App receives plain HTTP on internal port (never HTTPS)
        - Must trust `X-Forwarded-*` headers
        - Use `CLOUDRON_APP_ORIGIN` (includes `https://`) for base URL
        
        ---
        
        ## ๐Ÿ—๏ธ SECTION 2: Base Image Selection
        
        ### Decision Matrix (in priority order)
        
        | Priority | Image Type | When to Use | Example |
        |----------|-----------|-------------|---------|
        | **1st** | `cloudron/base:4.2.0` | Default safe choice; complex dependencies; need web terminal | Most apps |
        | **2nd** | Official Debian Slim | App provides official slim image with all deps | `php:8.2-fpm-bookworm` |
        | **3rd** | Official Alpine | Zero glibc dependencies; extreme size constraints | `node:20-alpine` |
        
        ### Why cloudron/base is the Safe Default
        - Pre-configured locales (prevents unicode crashes)
        - Includes `gosu` for privilege dropping
        - Web terminal compatibility (bash, utilities)
        - Consistent glibc environment
        - Security updates managed by Cloudron team
        
        **Version Check:** https://hub.docker.com/r/cloudron/base/tags
        
        ---
        
        ## โš ๏ธ SECTION 3: Framework-Specific Requirements
        
        ### PHP Applications
        ```bash
        # MANDATORY: Redirect temp paths to writable locations
        php_value[session.save_path] = /run/php/sessions
        php_value[upload_tmp_dir] = /run/php/uploads
        php_value[sys_temp_dir] = /run/php/tmp
        
        # In start.sh:
        mkdir -p /run/php/sessions /run/php/uploads /run/php/tmp
        chown -R cloudron:cloudron /run/php
        
        • Configure PHP-FPM pool to limit workers (prevent OOM)
        • Run composer install --no-dev --optimize-autoloader at build time

        Node.js Applications

        # Build time
        npm ci --production && npm cache clean --force
        
        # Runtime
        export NODE_ENV=production
        
        • node_modules stays in /app/code (never move to /app/data)
        • Clear npm cache in same Docker layer as install

        Python Applications

        # Environment
        export PYTHONUNBUFFERED=1  # Ensure logs stream properly
        export PYTHONDONTWRITEBYTECODE=1
        
        # Install globally (no virtualenv needed in container)
        pip install --no-cache-dir -r requirements.txt
        

        nginx (as sidecar/frontend)

        # MANDATORY: Writable temp paths
        client_body_temp_path /run/nginx/client_body;
        proxy_temp_path /run/nginx/proxy;
        fastcgi_temp_path /run/nginx/fastcgi;
        
        # In start.sh:
        mkdir -p /run/nginx/client_body /run/nginx/proxy /run/nginx/fastcgi
        
        # Listen on internal port, never 80/443
        listen 8000;
        

        Go/Rust Applications

        • Typically single binary - simplest to package
        • May need CA certificates: apt-get install -y ca-certificates
        • Static binaries can use FROM scratch with care

        ๐Ÿ’พ SECTION 4: Persistence Strategy (The Symlink Dance)

        The Core Pattern

        Application expects:    /app/code/config/settings.json  โ†’ READ-ONLY at runtime
        You must provide:      /app/data/config/settings.json  โ†’ Actually writable
        Solution:              Symlink /app/code/config โ†’ /app/data/config
        

        Implementation

        Build Time (Dockerfile):

        # Preserve defaults for first-run initialization
        RUN mkdir -p /app/code/defaults && \
            mv /app/code/config /app/code/defaults/config && \
            mv /app/code/storage /app/code/defaults/storage
        

        Runtime (start.sh๐Ÿ˜ž

        #!/bin/bash
        set -eu
        
        # === FIRST-RUN DETECTION ===
        if [[ ! -f /app/data/.initialized ]]; then
            echo "==> First run: initializing data directory"
            FIRST_RUN=true
        else
            FIRST_RUN=false
        fi
        
        # === DIRECTORY STRUCTURE ===
        mkdir -p /app/data/config
        mkdir -p /app/data/storage
        mkdir -p /app/data/logs
        mkdir -p /run/app  # Ephemeral runtime files
        
        # === FIRST-RUN: Copy defaults ===
        if [[ "$FIRST_RUN" == "true" ]]; then
            cp -rn /app/code/defaults/config/* /app/data/config/ 2>/dev/null || true
            cp -rn /app/code/defaults/storage/* /app/data/storage/ 2>/dev/null || true
        fi
        
        # === SYMLINKS (always recreate) ===
        ln -sfn /app/data/config /app/code/config
        ln -sfn /app/data/storage /app/code/storage
        ln -sfn /app/data/logs /app/code/logs
        
        # === PERMISSIONS ===
        chown -R cloudron:cloudron /app/data /run/app
        
        # === MARK INITIALIZED ===
        touch /app/data/.initialized
        

        Ephemeral vs Persistent Decision Guide

        Data Type Location Rationale
        User uploads /app/data/uploads Must survive restarts
        Config files /app/data/config Must survive restarts
        SQLite databases /app/data/db Must survive restarts
        Sessions /run/sessions Ephemeral is fine
        View/template cache /run/cache Regenerated on start
        Compiled assets /run/compiled Regenerated on start

        Memory Limit Guidelines

        App Type Recommended Notes
        Static/Simple PHP 128-256 MB
        Node.js/Go/Rust 256-512 MB
        PHP with workers 512-768 MB
        Python/Ruby 512-768 MB
        Java/JVM 1024+ MB JVM heap overhead
        Electron-based 1024+ MB

        Health Check Requirements

        • Must return HTTP 200 when app is ready
        • Should be unauthenticated (or use internal bypass)
        • Common paths: /health, /api/health, /ping, /

        ๐Ÿ”„ SECTION 8: Upgrade & Migration Handling

        Version Tracking Pattern

        CURRENT_VERSION="2.0.0"
        VERSION_FILE="/app/data/.app_version"
        
        if [[ -f "$VERSION_FILE" ]]; then
            PREVIOUS_VERSION=$(cat "$VERSION_FILE")
            if [[ "$PREVIOUS_VERSION" != "$CURRENT_VERSION" ]]; then
                echo "==> Upgrading from $PREVIOUS_VERSION to $CURRENT_VERSION"
                # Run version-specific migrations
            fi
        fi
        
        echo "$CURRENT_VERSION" > "$VERSION_FILE"
        

        Migration Safety

        • Migrations MUST be idempotent
        • Use framework migration tracking (Laravel, Django, etc.)
        • For raw SQL: CREATE TABLE IF NOT EXISTS, ADD COLUMN IF NOT EXISTS

            Very nice, would love to see the kind of packages this produces. I think a good quality measure would be to throw this prompt against an existing package and then it's easier to meausre.

                  @LoudLemur very good ... now that I can read it ๐Ÿ˜„

                  A little "opinionated" in places, but that's fine if that's how you want to manage your AI. I prefer a little looser. Some things have to be told (e.g, RO/RW), others can be more guided.


                  | S3 Storage | minio |

                  Hmm, should we be saying this ?
                  I don't recall the issues exactly about minio, just decided to stop using it as unreliable in terms of the future, so closed my mind to it. And I don't recall what is Cloudron official stance

                  In any case 'minio' is not listed in Addons in Cloudron docs, so this should not be in the same section as the other elements.

                  But plenty of S3 options, Hetzner, Scaleway, others. And I packaged GarageS3 with UI, which is working nicely for me (still a custom app)


                  cloudron/base:4.2.0

                  I am packaging everything with 5.0 now


                  Application expects:    /app/code/config/settings.json  โ†’ READ-ONLY at runtime
                  You must provide:      /app/data/config/settings.json  โ†’ Actually writable
                  Solution:              Symlink /app/code/config โ†’ /app/data/config
                  

                  I think some AI can mis-understand this, that the emphasis is not only that it should be in /app/data, but that it must be called settings.json

                  Better as :
                  /app/code/[config/][settings.json|config.json|.env]

                  AI will understand the point better.


                  Control your AI agent, but empower it - it has knowledge and experience which you don't have. If you're too dictatorial, you'll get what you have always got. A little bit of permissioning, and you might find some nice new more efficient ways of doing something.

                      @LoudLemur would it be more discoverable if it was published as a blog or docs site and then include llms.txt and llms-full.txt to make parsing easier for the agents?

                        Assuming this works, when the vibe coded unsecure app you found on github installs into cloudron, and is exposed to the internet does cloudron support still offer help or laugh at your self inflicted hole in foot?

                          Cloudron Packaging Assessment Toolkit: automated app assessment using AI

                          Following the discussion here about AI-assisted packaging, I have been building tooling to help assess applications before committing to packaging them. The core idea: the initial packaging is roughly 30% of the total effort. The other 70% is SSO integration, upgrade path testing, backup correctness, and ongoing maintenance. A good assessment upfront saves everyone time.

                          What it does

                          Give the assessment agent a GitHub URL and it produces a structured report with two scores:

                          • Structural difficulty (how hard to get it running): processes, databases, runtime, broker, filesystem writes, auth
                          • Compliance/maintenance cost (how hard to keep it running well): SSO quality, upstream stability, backup complexity, platform model fit, configuration drift risk

                          Each score comes with specific evidence from the repo's actual files, not guesses from the README alone. It reads the docker-compose.yml, Dockerfile, package manifests, and deployment docs.

                          I have used it to assess several wishlist apps and posted the results in their respective threads. The reports look like this (FacilMap example):

                          Structural difficulty: 1/14 (Trivial)
                          Compliance/maintenance cost: 3/13 (Low)
                          Confidence: High
                          
                          Single Node.js server, Sequelize ORM, MySQL or PostgreSQL via addon.
                          No native SSO (link-based access model). Requires external map tile
                          API keys for core routing features.
                          
                          Key risks:
                          - No SSO path (app design uses share links, not user accounts)
                          - External API keys needed for routing (ORS, Mapbox, MaxMind)
                          - socket.io needs WebSocket proxy config
                          

                          Each axis has an evidence column explaining what was found and where.

                          How to use it

                          You need a quality AI tool which can reach the internet:

                          1. Create a new AI Project
                          2. Paste the assessment agent instructions (linked below) into the Project Instructions
                          3. Optionally add the packaging reference document as Project Knowledge
                          4. Start a conversation and type: "Assess this app for Cloudron packaging: https://github.com/org/repo"

                          The agent fetches the repo, analyses it, and produces a report you can post directly into a wishlist thread.

                          What it cannot do

                          • It cannot test SSO, backup/restore, or upgrade paths. Those need a live Cloudron instance.
                          • It cannot predict upstream behaviour (licensing changes, breaking updates).
                          • Confidence scales with available evidence. An undocumented alpha project gets a low-confidence assessment.
                          • It tends to be slightly optimistic. When scores feel low for a complex app, check the compliance axis and the "key risks" section.

                          Files

                          All files are available here: https://forgejo.wanderingmonster.dev/root/cloudron-packaging

                          • example-assessment-facilmap.md โ€” full example report

                          The scorer HTML is a single 40 KB file with no dependencies. Open it locally or host it on Surfer.

                          If you have packaged an app and think the scores are wrong, I would love to hear about it. Calibrating against real experience is exactly what this needs. As @joseph suggested earlier in this thread, comparing against existing packages is the best quality measure.

                          The agent instructions and scoring rubric are plain markdown files. If you think an axis is missing or miscalibrated, the rubric is easy to edit.

                          There is a blog post introducing this here:

                            @LoudLemur would it be more discoverable if it was published as a blog or docs site and then include llms.txt and llms-full.txt to make parsing easier for the agents?
