Agent Tools
Every agent runs inside an agentbox container with access to a set of tools. Tools are registered at agent startup based on the agent’s configuration and the services available on the internal network. Some tools are always available; others require specific configuration flags or service connectivity.
| Tool | Description | Availability |
|---|
execute_command | Shell command execution with PTY | shell.enabled = true |
read_file | Read workspace files | shell.enabled = true |
write_file | Write files to workspace | shell.enabled = true |
list_directory | List directory contents | shell.enabled = true |
tmux | Persistent terminal sessions | shell.enabled = true |
browser | Playwright Chromium automation | shell.enabled = true |
git | Workspace version control | shell.enabled = true |
http_request | SSRF-protected external HTTP requests | Always |
save_knowledge | Persist notes to agent memory | AKM configured |
search_knowledge | Full-text search of agent memory | AKM configured |
search_shared_knowledge | Hybrid search across shared knowledge library | AKM configured |
shell.enabled = true in the agent’s tools configuration.
execute_command
Executes a shell command inside the agent container with a PTY (pseudo-terminal). Commands run against a binary allowlist — only explicitly permitted binaries can be invoked. Deny patterns block dangerous operations (e.g., rm -rf /, network reconfiguration).
| Parameter | Type | Description |
|---|
command | string | The shell command to execute |
timeout | integer | Optional execution timeout in seconds |
read_file
Reads the contents of a file in the agent’s workspace. Files up to 1 MB are returned in full. Paths are resolved relative to the workspace root.
| Parameter | Type | Description |
|---|
path | string | Relative or absolute path to the file |
write_file
Writes content to a file in the agent’s workspace. Parent directories are created automatically if they do not exist.
| Parameter | Type | Description |
|---|
path | string | Relative or absolute path to the file |
content | string | The content to write |
list_directory
Lists the contents of a directory, returning each entry’s name, type (file or directory), and size.
| Parameter | Type | Description |
|---|
path | string | Directory path to list (defaults to workspace root) |
tmux
Provides persistent terminal sessions via tmux. Agents can create named sessions, send commands to them, and read their output. Useful for long-running processes, background tasks, and managing multiple concurrent workstreams.
| Parameter | Type | Description |
|---|
action | string | The tmux operation (create, send, read, list, kill) |
session | string | Session name |
command | string | Command to send (for send action) |
browser
Controls a headless Playwright Chromium instance for web interaction. Supports navigation, screenshots, element clicking, text extraction, and JavaScript evaluation.
| Parameter | Type | Description |
|---|
action | string | The browser operation (navigate, screenshot, click, get_text, evaluate) |
url | string | Target URL (for navigate) |
selector | string | CSS selector (for click, get_text) |
script | string | JavaScript to evaluate (for evaluate) |
x | integer | Click x-coordinate (for click without selector) |
y | integer | Click y-coordinate (for click without selector) |
Version Control
git
Workspace-scoped Git operations. Agents can track changes, create commits, view diffs, and inspect history within their workspace.
| Parameter | Type | Description |
|---|
action | string | The git operation (status, add, commit, diff, log, init) |
args | string | Additional arguments for the operation |
message | string | Commit message (for commit) |
path | string | File path (for add, diff) |
HTTP
http_request
Makes HTTP requests to external APIs with built-in SSRF protection. Blocks requests to internal/private IP ranges (loopback, RFC 1918, link-local, Tailscale/CGNAT). Responses are capped at 50 KB and requests time out after 30 seconds.
| Parameter | Type | Description |
|---|
method | string | HTTP method (GET or POST) |
url | string | Target URL (must resolve to a public IP) |
headers | object | Optional request headers |
body | string | Optional request body (for POST) |
save_knowledge
Saves a knowledge entry to the agent’s persistent AKM memory. Entries survive across sessions and container restarts. Supports categorization by type for structured retrieval.
| Parameter | Type | Description |
|---|
title | string | Entry title |
content | string | Entry body (markdown supported) |
type | string | Entry type (note, plan, decision, journal) |
search_knowledge
Full-text search across the agent’s own knowledge entries. Uses PostgreSQL FTS with ranking and snippet highlighting.
| Parameter | Type | Description |
|---|
query | string | Search query (supports natural language) |
type | string | Optional filter by entry type |
limit | integer | Maximum number of results to return |
search_shared_knowledge
Searches the shared knowledge library using hybrid FTS and pgvector semantic search. Returns results from collections visible to the agent’s owner (owner-scoped and shared collections). Results include source citations.
| Parameter | Type | Description |
|---|
query | string | Search query |
collection_id | string | Optional filter by collection |
limit | integer | Maximum number of results to return |
