Skald Circle — SKALD

Installation

Stable release

curl -fsSL https://builds.skaldagent.net/install.sh | bash

Nightly (latest automatic build)

curl -fsSL https://builds.skaldagent.net/install-nightly.sh | bash

Requirements

Required	Notes
Docker	User container sandbox. The installer can install it
Linux (amd64/arm64) or macOS ARM64 (Apple Silicon)	Intel Mac not supported
systemd (Linux) or launchd (macOS)	For running as a service
Python 3 (optional)	For Python MCP servers (Gmail, GCal, GMaps, weather, SSH) and local TTS plugins
Node.js ≥ 18 (optional)	For WhatsApp MCP server

The installer checks each requirement and offers to install Docker if missing. Python and Node.js are optional — the server starts regardless, but certain MCP servers won't work.

What it does

1. Downloads the tarball from builds.skaldagent.net
2. Extracts to ~/.local/share/skald-circle/ (or $SKALD_DIR)
3. Configures the service (systemd user service / launchd agent)
4. Runs skald-setup to create the admin account
5. The server starts at https://localhost:8443

Uninstallation

curl -fsSL https://builds.skaldagent.net/install.sh | bash
# The tarball contains uninstall.sh:
~/.local/share/skald-circle/uninstall.sh

Or, after installation: ~/.local/share/skald-circle/uninstall.sh

From source

git clone https://github.com/.../skald-circle.git
cd skald-circle
cargo build --release
./run.sh

Current status

New application with agents and chatbots to help families and small groups collaborate, with supervised chat for children and vulnerable people.

Installer & startup architecture

install.sh
  ├── extracts tarball
  ├── creates .venv (inline — does NOT call run.sh)
  └── runs skald-setup for interactive config

systemd service → ExecStart=run.sh
  run.sh (supervisor)
    ├── creates .venv if it doesn't exist (for local dev)
    ├── runs skald-setup (first run only)
    └── loop: executes skald binary, restart on exit 255

Rule: install.sh must NEVER call run.sh. The venv is created inline in the installer. run.sh is only for the service supervisor or local development. skald-setup is the only setup executable called by install.sh.

Bug fix: install.sh stuck on "Setting up Python virtual environment" ✅

Problem: the installer called "$INSTALL_DIR/run.sh" to create the venv. But run.sh after the venv runs skald-setup and then the server in a loop, hanging the installer forever.

Fix: the venv is now created inline in install.sh and install-nightly.sh, using the same logic as run.sh (uv > python3) but without starting the server.

Bug fix: "Unit docker.service not found" in user service ✅

Problem: the systemd user unit had Requires=docker.service, but docker.service is a system-level unit (not a user unit). systemctl --user couldn't find it and refused to start Skald.

Fix: removed Requires=docker.service from the user unit template in both install scripts. Kept After=docker.service (advisory, doesn't block if the unit isn't found).

Bug fix: skald-setup non interattivo con curl | bash ✅

Problem: skald-setup controlla isatty(0), ma con curl ... | bash stdin è un pipe, quindi saltava senza chiedere username/password. L'installer arrivava fino in fondo ma senza aver creato l'admin.

Fix: se IS_INTERACTIVE=false ma /dev/tty esiste, l'installer chiama skald-setup </dev/tty.

Agent icons — completed ✅

All 11 agents now have Vector Paintings icons (painterly vector, warm and family-friendly), generated via ComfyUI:

Agent	Animal	Status
Main Assistant	🦊 Fox	✅
Project Coordinator	🦡 Badger	✅
Researcher	🐿️ Squirrel	✅
Generalist	🦫 Beaver	✅
Code Explorer	🕵️ Meerkat	✅
Software Architect	🏗️ Heron	✅
Software Engineer	🔧 Bear	✅
Spec Writer	📝 Owl	✅
Tech Lead	👑 Deer	✅
TIC	👁️ Cat	✅
Business Analyst	💼 Magpie	✅

Refactoring — completed ✅

• Removed Tauri/desktop dependency (tauri.conf.json, src/desktop/, icons/, docs/desktop.md, gen schemas/)
• Removed build.rs (no longer needed)
• New i18n system (core-api + plugin-mobile-connector + web)
• Configuration system refactoring

Auto-build CI/CD (NiPoGi)

Automatic build on NiPoGi with Gitea Actions (native runner v2.1.0):

Component	File	Status
ci/package.sh	Creates distribution tarballs from compiled binaries	✅
ci/verify-version.sh	Verifies that a release hasn't been built yet	✅
.gitea/workflows/nightly.yml	Push to main → build amd64+arm64 → nightly/	✅
.gitea/workflows/release.yml	PR check verify-version + merge → build → releases/v{ver}/	✅
Native runner on NiPoGi	v2.1.0, host-mode systemd service, label linux-amd64	✅
Cross toolchain (arm64)	gcc-aarch64-linux-gnu + rustup target add	✅
Caddy builds.skaldagent.net	file_server browse (directory listing)	✅
Route53 builds.skaldagent.net	A record → 145.40.169.107	✅
CI cache	Persistent CARGO_TARGET_DIR at /home/dguiducci/.cache/skald-ci/target	✅
install.sh	One-liner script `curl ...	bash` — Linux (systemd) + macOS ARM64 (launchd)
install-nightly.sh	One-liner script for nightly builds — same OS support	✅
uninstall.sh	Bundled in tarball — stops service/agent, removes everything	✅
releases/LATEST	Auto-updated by release workflow to track latest version	✅

Technical notes

• scripts/ in .gitignore — CI scripts moved to ci/ (tracked by git)
• Build without whisper-local on Linux (--no-default-features)
• aarch64-linux-gnu-strip for ARM64 binaries
• actions/checkout@v4 works (native runner has Node.js)
• macOS ARM64 supported via install.sh / install-nightly.sh (auto-detects OS, uses launchd)

Next steps

• Create release branch on Gitea with branch protection (PR via UI)
• Test release workflow with a PR
• Build first macOS ARM64 binary on MacBook, upload to builds.skaldagent.net

macOS support

Supported: macOS ARM64 (Apple Silicon M1+), Intel not supported.

Aspect	Status	Notes
Install script (install.sh)	✅	Auto-detects macOS, uses launchd
Nightly install (install-nightly.sh)	✅	Same logic
Uninstall script (uninstall.sh)	✅	Handles launchctl
Package script (ci/package.sh)	✅	Accepts --os darwin, strips best-effort
Binary	⏳ Not yet built	Build natively on MacBook, deploy to builds.skaldagent.net

How to build for macOS (on MacBook)

cargo build --release -p skald-setup -p skald  # includes whisper
./ci/package.sh --version v0.1.0 --os darwin --arch arm64 \
  --target-dir target/release --output dist/

Upload the resulting dist/skald-circle-v0.1.0-darwin-arm64.tar.gz to the NiPoGi's builds.skaldagent.net/releases/v0.1.0/ directory.

Cross-compilation from NiPoGi (research notes 🧪)

Cross-compiling for aarch64-apple-darwin from the NiPoGi using zig + cargo-zigbuild was attempted but hit blockers.

Component	Location	Notes
Zig	~/.local/bin/zig (symlink to /tmp/zig-linux-x86_64-0.14.0/zig)	v0.14.0, installed manually
macOS SDK	/opt/MacOSX/MacOSX11.3.sdk	From phracker/MacOSX-SDKs (GitHub)
Rust targets	aarch64-apple-darwin	via rustup target add
cargo-zigbuild	~/.cargo/bin/cargo-zigbuild	v0.23.0
zig wrapper scripts	/tmp/zig-wrap-cxx.sh, /tmp/zig-ar-wrap.sh	Handle OpenSSL/Clang flags + SDK paths

What works:

• ✅ Rust std compilation for macOS target
• ✅ OpenSSL compilation from source (via wrapper that remaps --target= and provides SDK headers)
• ✅ Rust dependency compilation (tree-sitter, sqlx, tokio, etc.)
• ✅ Single-file C programs compile and link correctly

What's blocked:

• ❌ zig cc segfaults with -F (framework search path) on Linux → can't link against macOS frameworks (CoreFoundation, Security)
• ❌ zig cc can't find frameworks without -F
• ❌ libsqlite3-sys build.rs bug: is_apple checks host.contains("apple") && target.contains("apple") → forces OpenSSL linkage instead of CommonCrypto on cross-compile (needs upstream fix or OPENSSL_DIR workaround)

The fix would be:

1. Upstream fix to libsqlite3-sys build.rs (target.contains("apple") only)
2. Zig fix for -F segfault, or use ld64 instead of zig's linker

Conclusion: Cross-compilation is fragile. Build natively on MacBook for now.
