modbender Compliance Checker
Assess OpenClaw skills against defined security policies. Track compliance posture across your skill inventory with framework-mapped findings and remediation tracking.
Why This Exists
Security scanners find vulnerabilities. Trust verifiers check provenance. But neither answers: "Does this skill meet our security policy?" Compliance Checker bridges the gap — define what "compliant" means for your environment, then assess every skill against those rules.
Quick Start
Define a policy
python3 {baseDir}/scripts/checker.py policy create --name "production" --description "Production deployment requirements"
Add rules to the policy
python3 {baseDir}/scripts/checker.py policy add-rule --policy "production" \
--rule "no-critical-findings" \
--description "No CRITICAL findings from skill scanner" \
--severity critical
python3 {baseDir}/scripts/checker.py policy add-rule --policy "production" \
--rule "trust-verified" \
--description "Must have VERIFIED or TRUSTED trust level" \
--severity high
python3 {baseDir}/scripts/checker.py policy add-rule --policy "production" \
--rule "no-network-calls" \
--description "No unauthorized network calls in scripts" \
--severity high
python3 {baseDir}/scripts/checker.py policy add-rule --policy "production" \
--rule "no-shell-exec" \
--description "No shell=True or subprocess calls" \
--severity medium
python3 {baseDir}/scripts/checker.py policy add-rule --policy "production" \
--rule "has-checksum" \
--description "Must have SHA-256 checksums for all scripts" \
--severity medium
Assess a skill against a policy
python3 {baseDir}/scripts/checker.py assess --skill "arc-budget-tracker" --policy "production"
Assess all installed skills
python3 {baseDir}/scripts/checker.py assess-all --policy "production"
View compliance status
python3 {baseDir}/scripts/checker.py status --policy "production"
Generate compliance report
python3 {baseDir}/scripts/checker.py report --policy "production" --format json
python3 {baseDir}/scripts/checker.py report --policy "production" --format text
Built-in Rules
The following rules are available out of the box:
| Rule | What it checks | Framework mapping |
|---|---|---|
no-critical-findings |
No CRITICAL findings from scanner | CIS Control 16, OWASP A06 |
no-high-findings |
No HIGH findings from scanner | CIS Control 16, OWASP A06 |
trust-verified |
Trust level is VERIFIED or TRUSTED | CIS Control 2 |
no-network-calls |
No unauthorized network requests | CIS Control 9, OWASP A10 |
no-shell-exec |
No shell execution patterns | CIS Control 2, OWASP A03 |
no-eval-exec |
No eval/exec patterns | OWASP A03 |
has-checksum |
SHA-256 checksums for all files | CIS Control 2 |
no-env-access |
No environment variable access | CIS Control 3 |
no-data-exfil |
No data exfiltration patterns | CIS Control 3, CIS Control 13 |
version-pinned |
All dependencies version-pinned | CIS Control 2 |
Compliance Status
Each skill-policy assessment produces one of:
- COMPLIANT — Passes all rules in the policy
- NON-COMPLIANT — Fails one or more rules
- EXEMPTED — Has approved exemptions for all failures
- UNKNOWN — Not yet assessed
Exemptions
Sometimes a skill legitimately needs to violate a rule (e.g., a network monitoring skill needs network access). Record exemptions with justification:
python3 {baseDir}/scripts/checker.py exempt --skill "arc-skill-scanner" \
--rule "no-network-calls" \
--reason "Scanner needs network access to check URLs against blocklists" \
--approved-by "arc"
Remediation Tracking
When a skill fails compliance, track the fix:
python3 {baseDir}/scripts/checker.py remediate --skill "some-skill" \
--rule "no-shell-exec" \
--action "Replaced subprocess.call with safer alternative" \
--status fixed
Storage
Compliance data is stored in ~/.openclaw/compliance/:
policies/— Policy definitions (JSON)assessments/— Assessment results per skill (JSON)exemptions/— Approved exemptions (JSON)remediations/— Remediation tracking (JSON)
Integration
Compliance Checker reads output from:
- arc-skill-scanner — vulnerability findings
- arc-trust-verifier — trust levels and attestations
Run a full pipeline:
# Scan → verify trust → assess compliance
python3 {baseDir}/scripts/checker.py pipeline --skill "some-skill" --policy "production"
