🍄‍🟫 Truffile

Python SDK/CLI for Truffle devices.

What It Does

• discovers and connects to your Truffle (scan, connect, disconnect)
• copies bundled agent resources into your workspace (load)
• validates and deploys apps from truffile.yaml (validate, deploy)
• manages installed apps (list apps, delete)
• talks to inference directly (models, chat)

Start making your Own Apps

• app schema and validation: truffile/truffile/schema/app_config.py
• schedule parsing: truffile/truffile/schedule.py
• deploy planning + builder flow: truffile/truffile/deploy/builder.py
• generated TruffleOS protos vendored in: truffile/truffle/
• bundled example apps live under truffile/app-store/
• bundled Codex skills live under truffile/skills/

truffile.yaml defines:

• metadata (name, description, type)
• process (cmd, working_directory, environment)
• files to upload
• optional run/build commands
• background schedule policy (for BG apps)

App Types and Runtime Model

Apps can be:

• foreground (fg): exposes MCP tools that tasks/agents can call during active execution
• background (bg): runs on schedule and emits context for proactivity, enabling the device to trigger actions and write/update memory
• both (fg + bg): one app package can provide MCP tools and scheduled context emission

How to think about it:

• FG path is tool-serving: app process is used as a callable capability surface (MCP)
• BG path is context/proactivity: scheduled runs feed the proactive agent with fresh signals
• Proactivity can take actions and persist memory based on BG outputs

In practice:

• use fg when you need direct tool invocation from tasks
• use bg when you need periodic monitoring, summaries, or event-driven context
• use both when the same app should both expose tools and continuously feed proactivity/memory

Core Commands

truffile scan
truffile connect <device>
truffile create [app_name]
truffile load all
truffile validate [app_dir]
truffile deploy [app_dir]
truffile deploy --dry-run [app_dir]
truffile list apps --json
truffile delete <app-name>
truffile models
truffile chat

truffile create scaffolds a hybrid app starter with:

• truffile.yaml (foreground + background process config)
• copy-file steps for generated *_foreground.py and *_background.py
• icon.png copied from docs/Truffle.png (deploy requires an icon)

truffile load all copies bundled agent-readable resources into your current workspace:

• ./truffile/skills/ for CLI/chat/infer/app-creation skills
• ./truffile/examples/ for bundled example apps such as ArXiv, Exa, Notion, Obsidian, Viator, WHOOP, and Home Assistant

Use truffile load skills or truffile load examples to copy only one group.

Obsidian Bridge Workflow

For a local Obsidian vault on your laptop, truffile can run a small host-side bridge and deploy a bundled foreground app to the device:

truffile obsidian attach --vault ~/Documents/abd-vault
truffile obsidian serve
truffile obsidian deploy

Use truffile obsidian status to inspect the saved bridge configuration. The bridge stores a scoped bearer token in the local truffile state file and the bundled app uses that token to read, write, list, and search notes in the configured vault.

In truffile chat, runtime controls are slash commands (not launch flags):

• /help for all chat commands
• /config to show current chat config
• /reasoning on|off
• /stream on|off
• /json on|off
• /tools on|off
• /max_tokens <int>, /temperature <float|off>, /top_p <float|off>, /max_rounds <int>
• /models to switch model
• /attach <path-or-url> to attach an image for the next user message (local path or http(s) URL)
• /system <text|clear>
• /mcp connect <http(s)://...>, /mcp tools, /mcp status, /mcp disconnect

Inference Interfaces

Direct IF2:

• list models: GET /if2/v1/models
• chat completions: POST /if2/v1/chat/completions

CLI wrappers:

• truffile models
• truffile chat (streaming by default)

Proto Sync

Refresh vendored protos from firmware repo:

./scripts/sync_protos.sh

Development Loop

The supported app development loop is CLI-first:

truffile create my-app --path ./apps
truffile validate ./apps/my-app
truffile deploy --dry-run ./apps/my-app
truffile deploy ./apps/my-app

After deploy, use truffile chat to attach the app to a task and exercise its tools with the on-device agent. Use truffile delete to remove test apps from the connected device.
