IMPORTANT: Always use OpenViking first for knowledge queries and memory storage

OpenViking Knowledge Base (Use First)

When querying information or files, always use OpenViking tools first before web search or other methods.

Search Resources

openviking_search(query: str, target_uri: str = None) -> str

Search for knowledge, documents, code, and resources in OpenViking. Use this as the first step for any information query.

Read Content

openviking_read(uri: str, level: str = "abstract") -> str

Read resource content from OpenViking. Levels: abstract (summary), overview, read (full content).

List Resources

openviking_list(uri: str, recursive: bool = False) -> str

List all resources at a specified path.

Search User Memories

user_memory_search(query: str) -> str

Search for user-related memories and events.

⚠️ CRITICAL: Commit Memories and Events

openviking_memory_commit(session_id: str, messages: list) -> str

All important conversations, events, and memories MUST be committed to OpenViking for future retrieval and context understanding.

Shell Execution

exec

Execute a shell command and return output.

exec(command: str, working_dir: str = None) -> str

Safety Notes:

• Commands have a configurable timeout (default 60s)
• Dangerous commands are blocked (rm -rf, format, dd, shutdown, etc.)
• Output is truncated at 10,000 characters
• Optional restrictToWorkspace config to limit paths

Web Access

web_search

Search the web using configurable backend (Brave Search, DuckDuckGo, or Exa).

web_search(query: str, count: int = 5, type: str = None, livecrawl: str = None) -> str

Returns search results with titles, URLs, and snippets. Requires API key configuration.

• count: Number of results (1-20, default 5)
• type (Exa only): Search type - "auto", "fast", or "deep"
• livecrawl (Exa only): Live crawl mode - "fallback" or "preferred"

web_fetch

Fetch and extract main content from a URL.

web_fetch(url: str, extractMode: str = "markdown", maxChars: int = 50000) -> str

Notes:

• Content is extracted using readability
• Supports markdown or plain text extraction
• Output is truncated at 50,000 characters by default

Image Generation

generate_image

Generate images from scratch, edit existing images, or create variations.

generate_image(
    mode: str = "generate",
    prompt: str = None,
    base_image: str = None,
    mask: str = None,
    size: str = "1920x1920",
    quality: str = "standard",
    style: str = "vivid",
    n: int = 1
) -> str

Modes:

• generate: Generate from scratch (requires prompt)
• edit: Edit existing image (requires prompt and base_image)
• variation: Create variations (requires base_image)

Parameters:

• base_image: Base image for edit/variation: base64 data URI, URL, or file path
• mask: Mask image for edit mode (optional, transparent areas indicate where to edit
• size: Image size (only "1920x1920" supported)
• quality: "standard" or "hd"
• style: "vivid" or "natural" (DALL-E 3 only)
• n: Number of images (1-4)

Communication

message

Send a message to the user (used internally).

message(content: str) -> str

Background Tasks

spawn

Spawn a subagent to handle a task in the background.

spawn(task: str, label: str = None) -> str

Use for complex or time-consuming tasks that can run independently. The subagent will complete the task and report back when done.

Scheduled Reminders (Cron)

Use the cron tool to create scheduled reminders:

Set a recurring reminder

# Every day at 9am
cron(
    action="add",
    name="morning",
    message="Good morning! ☀️",
    cron_expr="0 9 * * *"
)

# Every 2 hours
cron(
    action="add",
    name="water",
    message="Drink water! 💧",
    every_seconds=7200
)

Set a one-time reminder

# At a specific time (ISO format)
cron(
    action="add",
    name="meeting",
    message="Meeting starts now!",
    at="2025-01-31T15:00:00"
)

Manage reminders

# List all jobs
cron(
    action="list"
)

# Remove a job
cron(
    action="remove",
    job_id="<job_id>"
)

OpenViking Tools

openviking_read

Read content from OpenViking resources at different levels.

openviking_read(uri: str, level: str = "abstract") -> str

Levels:

• abstract: L0 - Brief summary
• overview: L1 - Medium overview
• read: L2 - Full content

openviking_list

List resources in an OpenViking path.

openviking_list(uri: str = "", recursive: bool = False) -> str

openviking_search

Search for resources in OpenViking using semantic search.

openviking_search(query: str, target_uri: str = None) -> str

openviking_grep

Search OpenViking resources using regex patterns.

openviking_grep(uri: str, pattern: str, case_insensitive: bool = False) -> str

openviking_glob

Find OpenViking resources using glob patterns.

openviking_glob(pattern: str, uri: str = "") -> str

user_memory_search

Search for user memories in OpenViking.

user_memory_search(query: str) -> str

Heartbeat Task Management

The HEARTBEAT.md file in the workspace is checked at regular intervals. Use file operations to manage periodic tasks:

Add a heartbeat task

# Append a new task
edit_file(
    path="HEARTBEAT.md",
    old_text="## Example Tasks",
    new_text="- [ ] New periodic task here\n\n## Example Tasks"
)

Remove a heartbeat task

# Remove a specific task
edit_file(
    path="HEARTBEAT.md",
    old_text="- [ ] Task to remove\n",
    new_text=""
)

Rewrite all tasks

# Replace the entire file
write_file(
    path="HEARTBEAT.md",
    content="# Heartbeat Tasks\n\n- [ ] Task 1\n- [ ] Task 2\n"
)
