  • SKILL.md covers When to use, Steps and PII categories detected
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Pii Detect is an agent skill from ruvnet/ruflo. Detect and flag personally identifiable information (PII) in text, code, and configurations. Use before committing code, writing logs, storing data, or sending model responses that might contain emails, phone numbers, SSNs, API keys, or passwords.

Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Model Context Protocol. The repository describes itself as: 🌊 The original agent harness. Deploy intelligent multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. Features adaptive memory…. The licence is MIT.

Example prompts

  • “/pii-detect”

Requirements

  • Pre-approved tools (allowed-tools): mcp__plugin_ruflo-core_ruflo__aidefence_has_pii, mcp__plugin_ruflo-core_ruflo__aidefence_scan, mcp__plugin_ruflo-core_ruflo__aidefence_analyze, mcp__plugin_ruflo-core_ruflo__transfer_detect-pii, Bash

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Quick PII check — call mcpplugin_ruflo-core_rufloaidefence_has_pii with the text for a boolean result
  2. Detailed scan — call mcpplugin_ruflo-core_ruflotransfer_detect-pii for categorized PII findings
  3. Full analysis — call mcpplugin_ruflo-core_rufloaidefence_analyze for context-aware PII detection
  4. If PII found, flag the specific locations and suggest redaction

What it can do on your machine

Read from SKILL.md and the folder at commit 6051f67. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • mcp__plugin_ruflo-core_ruflo__aidefence_has_pii
    • mcp__plugin_ruflo-core_ruflo__aidefence_scan
    • mcp__plugin_ruflo-core_ruflo__aidefence_analyze
    • mcp__plugin_ruflo-core_ruflo__transfer_detect-pii
    • Bash

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Pii Detect loads about 350 tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 104 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~350

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: mcp__plugin_ruflo-core_ruflo__aidefence_has_pii, mcp__plugin_ruflo-core_ruflo__aidefence_scan, mcp__

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

PII Detection

Detect personally identifiable information before it enters logs, commits, or responses.

When to use

Before committing code, storing data, or sending responses that might contain PII (emails, phone numbers, SSNs, API keys, passwords).

Steps

  1. Quick PII check — call mcp__plugin_ruflo-core_ruflo__aidefence_has_pii with the text for a boolean result
  2. Detailed scan — call mcp__plugin_ruflo-core_ruflo__transfer_detect-pii for categorized PII findings
  3. Full analysis — call mcp__plugin_ruflo-core_ruflo__aidefence_analyze for context-aware PII detection
  4. If PII found, flag the specific locations and suggest redaction

PII categories detected

  • Email addresses, phone numbers
  • Social security numbers, tax IDs
  • Credit card numbers
  • API keys, tokens, passwords
  • Physical addresses
  • Names linked to sensitive data
