## What it does

The skill scans project outputs (defaulting to `output/`) across `.csv`, `.tex`, `.log`, `.smcl`, and markdown files. It flags cell counts below the threshold (default `n<10`), exact integers isolating single entities, and PII patterns such as Social Security numbers or addresses. It also detects incomplete suppression, where missing values can be calculated from row and column totals.

Findings are grouped into CRITICAL, WARNING, and OK statuses. Any CRITICAL finding triggers a non-zero exit code to block export staging. For every issue, the skill suggests specific remediation steps: suppress paired margins, round totals to a base, aggregate categories, or drop unsafe statistics. It never modifies files directly, keeping editing decisions with the analyst.

Rule profiles are selected with `--provider` using `census`, `irs`, `irb`, or `generic`. Without signed contract parameters, the check falls back to conservative generic defaults. This automated check operates strictly as a pre-screen on your workstation, not as a replacement for formal data provider review.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add pedrohcgs/claude-code-my-workflow --skill disclosure-check -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/disclosure-check/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/disclosure-check/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add pedrohcgs/claude-code-my-workflow --skill disclosure-check -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/disclosure-check/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add pedrohcgs/claude-code-my-workflow --skill disclosure-check -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/disclosure-check/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install pedrohcgs/claude-code-my-workflow disclosure-check
```

2. **Manually: put the files in place**

```

2. **Platform CLI**
```bash
gemini skills install https://github.com/pedrohcgs/claude-code-my-workflow --path .claude/skills/disclosure-check
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/disclosure-check/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**

npx skills add pedrohcgs/claude-code-my-workflow --skill disclosure-check -a opencode
```

### Claude.ai

**Claude.ai**

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/pedrohcgs/claude-code-my-workflow/tree/HEAD/.claude/skills/disclosure-check/SKILL.md

## When to use it
- Catch small table cell counts before submitting outputs to an RDC review
- Identify PII leaks like SSNs or coordinates in econometric output logs
- Detect complementary-suppression holes that let readers recalculate suppressed cells
- Check aggregated figures against p-percent and (n,k) dominance rules

## Example prompts
- /disclosure-check output/ --provider census
- Run a disclosure check on to_review/ --provider irs --threshold 15
- Pre-screen the outputs directory for RDC export compliance

# `/disclosure-check` — Statistical-Disclosure-Limitation pre-screen

Scan analysis outputs built on **restricted or confidential data** (Census FSRDC, IRS SOI, administrative registers, linked health records, proprietary firm panels) for the disclosure-avoidance problems that get an export request rejected — *before* it reaches the data provider's official disclosure review. The skill is a **pre-screen, not a substitute** for that review.

**Core principle:** A single un-suppressed `n=3` cell, an exact count that pins down one firm, or a `p`-percent dominance failure can re-identify a person or establishment. Catch it on your machine, not in the rejection email from the RDC analyst.

## When to use

- **Before requesting an export** from a Census FSRDC / secure data enclave / RDC.
- **Before depositing** restricted-data results to openICPSR, a journal, or a co-author outside the enclave.
- **Before sharing any figure, table, or log** derived from confidential microdata.
- **As a release gate.** Pair with a pre-commit / pre-deposit invocation so no restricted-data output ships un-screened. This is the foundation of the data-management plan for any restricted-data project.

## Inputs

- `$0` — outputs directory to scan. Defaults to `output/`, where every language's pipeline writes; if it does not exist but a pre-v2.6 `scripts/<lang>/_outputs/` does, scan that and say so. Also accepts any export-staging directory (e.g., a `to_review/` folder the analyst stages for the RDC).
