pii-sweep

pii-sweep is a skill for Claude Code from TimSimpsonJr/magpie. It costs 136 tokens per session (2,407 once invoked), scanned A, original, MIT.

A privacy-audit tool for counting personal information exposed in a free-text reason or narrative column from a public-records or audit dataset. It counts names and structured identifiers such as Social Security numbers, A-numbers, and dates of birth, weighting results by row counts.

In plain words
What is it for?
Use it to measure personal-information exposure in a FOIA or audit-log text field. The matched examples remain local for later redaction, while the aggregate counts can be published.
Why use it?
It produces a reproducible headline tally without exposing the matched text. It also separates officials named for accountability from personal information that should have been removed.

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

pii-sweep scanned grade A with 0 findings 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.

pii-sweep

Produce Magpie's authoritative PII-exposure tally over one FOIA / audit-log free-text column (the reason / narrative / justification field): spaCy en_core_web_lg PERSON NER plus structured-identifier regex, run over the distinct values and weighted by row counts, splitting officials (named for accountability) from PII that should have been sanitized. The aggregate tally is the publishable headline; the matched texts stay LOCAL and feed redact-output (Phase 7). This is the engine behind the recipe's pii check — that check is a fast presence indicator; this is the authoritative count.

One deterministic engine does the work; the agent orchestrates the prep and the output:

  • scripts/pii_sweep.py::sweep(series, ...) — the distinct → classify → weight → tally pass (pure core; spaCy only at the lazy classifier edge).

The pure core is golden-tested with a fake classifier (no 400 MB model). The verified spaCy facts, the NER-label scope, and the candidate pattern set live in references/prior-art.md (the Phase 5 research gate) — consult it before changing a model call or a regex. pii-sweep shares NO code with recipe.check_pii in either direction (a drift test guards the overlapping patterns), so importing it stays ML-free until sweep actually runs.

The pipeline

Run the steps in order.

  1. Prep the source via dataset-analyze (load_table → data_quality gate → derive). The sweep runs on ONE column: the cleaned free-text reason / narrative series. Gate on truncation FIRST — never sweep a silently-truncated export.

  2. Build the officials lexicon from the STRUCTURED column — not from the free text. Take the searcher / user / requesting-agency field (the structured identity already in the export) and pass its distinct values as official_names=. sweep normalizes each into name tokens and marks a PERSON span official when an official's tokens are a subset of the span (robust to spaCy span over-extension) OR a rank/title token immediately precedes the span (Sgt, Officer, Deputy, ...). This is how an UNTITLED official ("Dana Wheeler ran the plate") is still attributed for accountability rather than counted as exposed PII.

pii-sweep is a skill published in the GitHub repository TimSimpsonJr/magpie (2 stars, last pushed 3mo ago), licensed MIT. It adds 136 tokens to every session and 2,407 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
