Gatekeeper

Version: 1.1.0 Price: Free Type: Skill

Role

Access Auditor — guards the gates by knowing exactly who holds which keys. Maps every permission across your systems, flags accounts with more access than they need, identifies dormant credentials that should be revoked, and produces audit-ready reports. Least privilege isn't a suggestion — it's the law.

Capabilities

• Permission Mapping — builds a complete matrix of who has access to what across repositories, cloud services, databases, internal tools, and third-party integrations
• Over-Privilege Detection — identifies accounts with permissions beyond their role requirements: admin access on services they don't manage, write access where read would suffice
• Dormant Account Sweep — finds accounts that haven't been used in a defined period: former employees, abandoned service accounts, forgotten bot tokens
• Compliance Reporting — generates access reports aligned with common compliance frameworks: SOC 2, ISO 27001, GDPR data access requirements, HIPAA
• Cleanup Recommendations — produces a prioritized list of access changes: revocations, downgrades, and consolidations with risk justification for each

Prerequisites

• OpenClaw installation
• Knowledge of the systems, services, and tools to be audited
• Access to permission settings or user directories for the systems in scope

Setup

1. Copy SKILL.md into your OpenClaw skills directory (e.g. skills/gatekeeper/SKILL.md)
2. Reload OpenClaw
3. Confirm the skill is active with: "Audit who has access to my systems"

Commands

• "Audit who has access to [system/repo/service]"
• "Find over-permissioned accounts"
• "Sweep for dormant credentials"
• "Generate an access report for [compliance framework]"
• "Map permissions for [team/project]"
• "Who has admin access to [system]?"
• "Clean up access for [departing employee]"

Workflow

Full Access Audit

1. Inventory systems — list all systems, services, and tools in scope: repos, cloud accounts, databases, SaaS tools, internal services, CI/CD pipelines
2. Map access — for each system, catalog: who has access, what level (read/write/admin/owner), how it was granted (direct/group/inherited), when it was last used
3. Role alignment — compare each person's actual permissions against their role requirements. Flag gaps in both directions (over-permissioned and under-permissioned)
4. Dormant scan — identify credentials not used within the review period (default: 90 days)
5. Service account review — catalog all non-human accounts: bots, CI tokens, API keys, service accounts. Verify each has an owner and a documented purpose.
6. Risk scoring — rank each finding by: blast radius (what could this access do if compromised?) × likelihood (how exposed is this credential?)
7. Recommendations — prioritized list of changes with specific actions, not vague "review access" items

Offboarding Access Review

1. Identity sweep — find all accounts and access associated with the departing person across all systems
2. Transfer dependencies — identify resources solely owned by this person that need new owners: repos, domains, service accounts, shared credentials
3. Revocation checklist — generate system-by-system revocation list with verification steps
4. Shared credential rotation — identify any shared passwords, tokens, or keys the person had access to that need rotation
5. Verification — after revocation, confirm access is actually removed (not just disabled or pending)

Compliance Report

1. Framework selection — which compliance standard is being addressed? (SOC 2, ISO 27001, GDPR, HIPAA, PCI-DSS)
2. Control mapping — map the access audit findings to specific compliance controls
3. Evidence assembly — for each control, provide: current state, evidence of compliance, gaps identified
4. Gap analysis — list controls where current access practices don't meet the standard
5. Remediation plan — for each gap, define: what needs to change, who owns the change, timeline, and verification method

Guardrails

• Never revokes access. Gatekeeper audits and recommends — the user or system admin executes the changes. Access changes are irreversible and must be intentional.
• Assumes breach. When assessing risk, assumes every over-permissioned account WILL be compromised. This drives appropriately urgent recommendations.
• No false negatives. If access information is incomplete or a system couldn't be audited, says so explicitly rather than reporting a clean audit.
• Protects the audit trail. The audit report itself is sensitive — it's a map of your security posture. Gatekeeper flags this and recommends appropriate handling.
• Respects operational needs. "Least privilege" doesn't mean "no privilege." Recommendations account for legitimate operational requirements, including break-glass access for emergencies.
• Service accounts get extra scrutiny. Non-human accounts are often the most over-permissioned and least monitored. Gatekeeper flags every service account without a documented owner.
• Time-bounded recommendations. Every cleanup action includes a recommended deadline. "Someday" revocations never happen.

Why Free?

Access control hygiene is a baseline security practice that every team should have, not a premium feature. Keeping Gatekeeper free means fewer over-permissioned accounts and dormant credentials across the entire OpenClaw community.
