Description
Redacta pseudonymises medical documents — replacing patient identifiers (NHS numbers, dates of birth, postcodes, phone numbers, hospital numbers) with labell...
Usage Guidance
This skill appears coherent and lightweight, but check the following before using on real patient data: 1) Model/data handling: the SKILL.md says processing is "local" but actual text may be sent to whatever language model you use—confirm your model provider's data processing and retention policies or run models on-prem if required. 2) Clinician/institution names: the default preserves clinician and hospital names; if your policy requires removing staff or institutional identifiers, instruct the agent to redact them or change the rule. 3) Review outputs: the skill admits it cannot guarantee 100% detection — always manually review pseudonymised text and the redaction report before sharing. 4) Test first: run the skill on representative non-sensitive examples to validate regex/context rules (especially NHS check-digit behaviour and date-context decisions). 5) Scope limits: v1 is text-only (no PDFs/images). If you need stronger guarantees or audit logging, consider integrating with a vetted de-identification pipeline rather than relying solely on instruction-driven redaction.
Capability Analysis
Type: OpenClaw Skill Name: redacta Version: 1.0.0 The OpenClaw skill 'redacta' is designed to pseudonymise medical documents by replacing patient identifiers with tokens. The `SKILL.md` instructions explicitly state that the skill does not store or transmit patient data, and it instructs the AI agent to never output original patient identifiers. There are no instructions for data exfiltration, unauthorized command execution, network calls beyond the stated purpose, or any form of prompt injection against the agent to perform malicious actions. The skill's behavior is clearly aligned with its stated privacy-preserving purpose.
Capability Assessment
Purpose & Capability
The name/description (pseudonymise medical documents) matches the SKILL.md instructions. No unrelated binaries, env vars, or installs are requested and the detection rules and output format align with the stated purpose.
Instruction Scope
The instructions are narrowly scoped to text pseudonymisation and list precise regex and contextual rules. Two design choices merit user attention: (1) clinician and institutional names are preserved by default (may leak staff/institution PII in some contexts) and (2) the SKILL.md asks the agent to process text "locally within your AI agent session" but also acknowledges underlying language-model processing; the skill cannot enforce local-only model hosting — platform/model choices determine actual data flow.
Install Mechanism
Instruction-only skill with no install steps or code files; nothing is written to disk or downloaded as part of the skill itself.
Credentials
No environment variables, credentials, or config paths are required. The skill does not request unrelated secrets or permissions.
Persistence & Privilege
No elevated persistence requested (always:false). The skill does not attempt to modify other skills or system-wide settings.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install redacta
  3. After installation, invoke the skill by name or use /redacta
  4. Provide required inputs per the skill's parameter spec and get structured output
