Description
Local PII protection for OpenClaw agents. Scrubs customer data (names, phones, emails, addresses, credit cards, vessel names) before it reaches any AI model....
Usage Guidance
This skill appears to do what it says: run local Presidio containers, anonymize customer data before sending it to models, then restore locally. Before installing: 1) Ensure you run the Presidio containers from a trusted source (the skill references mcr.microsoft.com/presidio images). 2) Treat the mapping directory (~/.openclaw/presidio/mappings by default) as highly sensitive — restrict access, exclude it from backups if appropriate, and monitor deletion success. 3) Test failure modes: confirm that mapping files are deleted after restore and that blocked behavior triggers when containers are down. 4) If you operate on shared machines or backups, consider changing PRESIDIO_MAPPING_DIR to a secure location and audit it. 5) Review network rules so containers cannot exfiltrate data (the scripts call localhost only but container config matters). If you need, run a short security review or penetration test focused on mapping file handling and container network isolation before deploying in production.
Capability Analysis
Type: OpenClaw Skill
Name: presidio-pii-skill
Version: 0.1.1
The presidio-pii skill implements local PII protection by routing sensitive data through Microsoft Presidio Docker containers on localhost. It features scripts for health monitoring (presidio-health.sh), reversible anonymization (presidio-scrub.py), and restoration (presidio-restore.py) using local mapping files with restricted permissions (chmod 600). The logic is transparent, lacks external network calls, and includes a 'fail-closed' policy in SKILL.md to prevent data leakage if the protection service is offline, aligning perfectly with its stated security purpose.
Capability Assessment
Purpose & Capability
Name/description (local PII scrubber) match the required binaries (docker, python3, curl), included scripts, and the declared container images (Microsoft Presidio). The dependencies are proportionate to the stated goal.
Instruction Scope
Runtime instructions only call local endpoints (analyzer/anonymizer on localhost) and tell the agent to scrub before model queries and restore afterward. The scripts use environment variables (PRESIDIO_ANALYZER_URL, PRESIDIO_ANONYMIZER_URL, PRESIDIO_MAPPING_DIR) if present — SKILL.md does not list those env vars explicitly but their use is limited and reasonable. The fail-closed behavior is enforced in scripts.
Install Mechanism
There is no remote arbitrary code download; images referenced are from mcr.microsoft.com (official Microsoft container registry). The skill has no install script that fetches code from unknown URLs. It's instruction-only with local scripts included.
Credentials
The skill requests no external credentials and runs entirely against localhost. However it writes reversible mapping files containing original PII to a local mapping directory (default ~/.openclaw/presidio/mappings). The mapping files are chmod 600 and deleted by default after restore, but deletion can fail or be overridden via --keep; users should treat this as sensitive data and secure the mapping directory and backups.
Persistence & Privilege
The skill is not always-enabled and does not request elevated platform privileges. It does persist mapping files locally for the duration of a session, which is expected for reversible pseudonymization.
