openclaw-bastionPrompt injection defense for agent workspaces. Scan files for injection attempts, analyze content boundaries, detect hidden instructions, and maintain command allowlists. Free alert layer — upgrade to openclaw-bastion-pro for active blocking, sanitization, and runtime enforcement.
Install via ClawdBot CLI:
clawdbot install AtlasPA/openclaw-bastionRuntime prompt injection defense for agent workspaces. While other tools watch workspace identity files, Bastion protects the input/output boundary — the files being read by the agent, web content, API responses, and user-supplied documents.
Agents process content from many sources: local files, API responses, web pages, user uploads. Any of these can contain prompt injection attacks — hidden instructions that manipulate agent behavior. Bastion scans this content before the agent acts on it.
Scan files or directories for prompt injection patterns. Detects instruction overrides, system prompt markers, hidden Unicode, markdown exfiltration, HTML injection, shell injection, encoded payloads, delimiter confusion, multi-turn manipulation, and dangerous commands.
If no target is specified, scans the entire workspace.
python3 {baseDir}/scripts/bastion.py scanScan a specific file or directory:
python3 {baseDir}/scripts/bastion.py scan path/to/file.md
python3 {baseDir}/scripts/bastion.py scan path/to/directory/Fast single-file injection check. Same detection patterns as scan, targeted to one file.
python3 {baseDir}/scripts/bastion.py check path/to/file.mdAnalyze content boundary safety across the workspace. Identifies:
python3 {baseDir}/scripts/bastion.py boundariesDisplay the current command allowlist and blocklist policy. Creates a default .bastion-policy.json if none exists.
python3 {baseDir}/scripts/bastion.py allowlist
python3 {baseDir}/scripts/bastion.py allowlist --showThe policy file defines which commands are considered safe and which patterns are blocked. Edit the JSON file directly to customize. Bastion Pro enforces this policy at runtime via hooks.
