PrivateInvestigator

PrivateInvestigator is a skill for Claude Code, Codex from danielmiessler/LifeOS. It costs 120 tokens per session (2,342 once invoked), scanned A, original, MIT.

A public-data research workflow for finding people and checking whether identity details refer to the same person. It searches people-finding sites, social media, public records, and reverse lookups for phone numbers, emails, images, or usernames.

In plain words
What is it for?
Use it to locate someone, reconnect with a lost contact, or verify an identity using publicly available information.
Why use it?
A person may appear under different names or accounts, and a single matching detail can be misleading. The workflow compares multiple identifiers and reports confidence in the result.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

PrivateInvestigator scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Customization

Before executing, check for user customizations at: ~/.claude/LIFEOS/USER/CUSTOMIZATIONS/SKILLS/PrivateInvestigator/

If this directory exists, load and apply any PREFERENCES.md, configurations, or resources found there. These override default behavior. If the directory does not exist, proceed with skill defaults.

🚨 MANDATORY: Voice Notification (REQUIRED BEFORE ANY ACTION)

You MUST send this notification BEFORE doing anything else when this skill is invoked.

  1. Send voice notification:

    curl -s -X POST http://localhost:31337/notify \
      -H "Content-Type: application/json" \
      -d '{"message": "Running the WORKFLOWNAME workflow in the PrivateInvestigator skill to ACTION"}' \
      > /dev/null 2>&1 &
    
  2. Output text notification:

    Running the **WorkflowName** workflow in the **PrivateInvestigator** skill to ACTION...
    

This is not optional. Execute this curl command immediately upon skill invocation.

PrivateInvestigator - Ethical People Finding

What It Does

Finds people and verifies identities using public data only. It covers people-search aggregators, social media, public records, and reverse lookups in parallel, then scores results by confidence (HIGH/MEDIUM/LOW/POSSIBLE) and trusts a match only when 3+ independent identifiers align.

The Problem

Finding a real person from a name, a phone number, or an email is scattered across dozens of sources — people-search sites, county records, court portals, social platforms, reverse-lookup services — and no single one gives you the answer. Common names make it worse: search "John Smith" and you get thousands of people, most of them the wrong one. Run the searches one at a time and you either give up before you've covered enough sources or you act on a single weak match and contact the wrong person. This skill runs the sources in parallel and refuses to call a match real until several independent identifiers line up.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
