## What it does

The skill processes an alert from a SAST scan or pentest report across sequential verification steps. First, it strips automated boilerplate and restates the technical weakness, file location, and exploit preconditions. It then checks whether the code path is reachable in your environment using `Read`, `Grep`, or `Bash`.

Severity ratings adjust to your context. Flags on `devDependencies` or unreachable dead code are marked as false positives without changing production code. For verified issues, the triage assigns one of three outcomes: immediate fix, deferral, or risk acceptance.

Downgrading severity just to justify deferral is rejected by the workflow. Deferring keeps the original rating honest. Accepting risk requires three explicit fields: why a fix does not apply, active compensating controls, and a trigger for re-evaluation.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill finding-triage -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill finding-triage -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill finding-triage -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install briiirussell/cybersecurity-skills finding-triage
```

2. **Manually: put the files in place**
- File: `.github/skills/finding-triage/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill finding-triage -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/briiirussell/cybersecurity-skills --path skills/finding-triage
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill finding-triage -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- triage SAST and dependency scanner alerts
- verify code path reachability in project dependencies
- adjust raw CVSS severity to application context
- document accepted risks with required compensating controls

## Example prompts
- Triage this finding from our security audit
- Is this dependency vulnerability a real threat or a false positive?
- Draft an accepted risk writeup for the scanner alert in src/db.ts

# Finding Triage — Single-Finding Disposition with Defensible Justification

Every other skill in this repo *generates* findings. This skill *closes the loop* — for a single finding, walk through whether it's real, what severity it deserves in your context, and what to do about it. Output is a complete ticket-ready writeup with the right fields, the right justification, and an audit trail that survives a regulator reading it six months later.

The dispositions match `owasp-audit`'s Three-Disposition rule: **Fixed**, **Deferred**, or **Accepted Risk**. False positive is a fourth — but it isn't a disposition for a real finding, it's a determination that there *is* no finding.

This skill works on findings from any source: SAST output, DAST scanner, dependency advisory, manual audit, threat-hunt hit, pentest report, vendor disclosure, internal red-team writeup, bug bounty submission.

Cross-references:
- `vuln-research` for the technical CVE deep-dive that feeds reachability assessment here
- `owasp-audit` Three-Disposition rule (the framework this implements per-finding)
- `security-comms` for translating the disposition writeup into stakeholder-readable language when the finding has to leave the security context
- Any audit skill — this consumes their findings as input

## Workflow

The agent works through these steps with the user. Stop and ask clarifying questions where the user has context the finding alone doesn't reveal.

### Step 1 — Restate the finding in your own words

If the finding came from a scanner, restate what's actually being claimed. Scanners produce noise; restating filters out the boilerplate.

A good restatement names:
- **What** the issue is (specific weakness — CWE if applicable)
- **Where** it lives (file:line, endpoint, resource ARN, host)
- **How** it could be exploited (preconditions, attacker capability needed)
- **Impact** if it were exploited (data loss, privilege escalation, availability)

If you can't restate it clearly, you don't understand it yet. Ask the user for context.

### Step 2 — Is this actually true?

Half of automated-scanner findings are false positives by volume. The triage:

| Question | If yes | If no |
|---|---|---|
```
