Distil PII Redactor

Use this skill when the user asks to redact, anonymize, sanitize, or remove PII or personal data from text. It runs a local Distil-PII GGUF model through llama-server; raw text must not be sent to external APIs.

Privacy Rules

• Do not quote, summarize, or repeat raw PII in chat.
• Prefer file-based input and output when the sensitive text is already in a file or attachment.
• Return only the redacted text unless the user is explicitly debugging the redactor itself.
• If the user asks for only the LLM or redaction output, do not narrate setup, server status, tool use, or validation details in the final response.
• Do not use --show-entities in normal workflows. It emits original values.
• Do not store raw PII in tracked files, shell history, long-lived notes, or logs.
• This skill declares no external credentials. If a downstream tool needs authentication, use that tool's HybridClaw secret_ref or gateway secret injection and pass only redacted text downstream.
• Do not convert raw PII into HybridClaw secrets. Secret refs are for credentials and auth material, not a transport for user data.

Setup

If llama-server is missing, install it with:

hybridclaw skill install distil-pii-redactor llama-server

or install llama.cpp manually. This skill intentionally has no credentials: frontmatter because local inference does not need API keys; any future remote-provider variant must declare secret_ref credentials instead of reading raw environment variables.

Start the local server:

bash skills/distil-pii-redactor/scripts/setup.sh

The setup script stores the model under ~/.hybridclaw/distil-pii by default, downloads the public Distil-PII 1B GGUF model if missing, and starts llama-server on 127.0.0.1:8712.

Stop the server:

bash skills/distil-pii-redactor/scripts/stop.sh

Redaction Workflow

For files, keep raw input and redacted output on disk:

python3 skills/distil-pii-redactor/scripts/redact.py \
  --input-file sensitive.txt \
  --output-file redacted.txt

For stdin:

python3 skills/distil-pii-redactor/scripts/redact.py < sensitive.txt

For short text that is already in the conversation, pass it directly only when there is no lower-exposure path:

python3 skills/distil-pii-redactor/scripts/redact.py "text to redact"

The default output is only redacted_text, with sensitive spans replaced by tokens such as [PERSON], [EMAIL], [PHONE], [ADDRESS], [SSN], [CARD_LAST4:1234], and [IBAN_LAST4:1234].

The redactor refuses non-loopback --server-url values by default. Use --unsafe-allow-remote only for an explicitly trusted endpoint after the user accepts that raw text will leave the local machine.

Debug Output

Use --show-entities only while testing the redactor, because it includes the original sensitive values:

python3 skills/distil-pii-redactor/scripts/redact.py --show-entities \
  --input-file fixture.txt

Do not paste debug JSON back to the user unless they explicitly requested it and understand that it contains original PII.

Validation

Run:

python3 skills/skill-creator/scripts/quick_validate.py skills/distil-pii-redactor
python3 skills/distil-pii-redactor/scripts/redact.py --help
bash -n skills/distil-pii-redactor/scripts/setup.sh
bash -n skills/distil-pii-redactor/scripts/stop.sh
