## What it does

security can review code by hand and use scanners. It looks for vulnerabilities, exposed secrets, dependency risks, and issues in prompt surfaces. Its report tracks each relevant risk class as a finding, clean, or not assessed, and separates behavior verified by a test from concerns inferred from code.

The review is read-only by default and limited to projects you own or are authorized to assess. A missing or failing scanner counts as a coverage gap, not a clean result; use `--require-tools` when complete tool coverage is required. The skill reports findings and remediation classes, but leaves patches and ship decisions to the caller.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add boshu2/agentops --skill security -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add boshu2/agentops --skill security -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add boshu2/agentops --skill security -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install boshu2/agentops security
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add boshu2/agentops --skill security -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/boshu2/agentops --path skills/security
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add boshu2/agentops --skill security -a opencode
```

### Claude.ai

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

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/boshu2/agentops/tree/HEAD/skills/security/SKILL.md

## When to use it
- find vulnerabilities in code and handlers
- check dependencies for supply-chain risks
- locate exposed secrets in a repository
- review prompt surfaces for security issues
- separate verified behavior from code-based suspicions

## Example prompts
- Review this repository for vulnerabilities, exposed secrets, and dependency risks before release.
- Check this handler for security issues and report any gaps in coverage.
- Assess the repository's prompt surfaces and separate verified findings from suspected ones.

# Security Skill

> **Purpose:** Find and report security weaknesses in code, scripts, authorized binaries, and repo-managed prompt surfaces, with honest coverage.

Use this skill for a caller-requested security review of code or of a plan or design before code exists, a repository scan, authorized binary assurance, dependency risk, secrets, or offline prompt-surface redteam.

## Critical Constraints

- Scan only repositories, binaries, and prompt surfaces the operator owns or is explicitly authorized to assess. **Why:** a security review does not grant access to third-party systems or proprietary material.
- Keep collection read-only by default; do not exfiltrate secrets, execute destructive payloads, or mutate policy/baselines to manufacture green. **Why:** the assessment must not become the incident or erase its evidence.
- Treat missing/error scanners as a coverage gap, never a clean finding; use `--require-tools` when complete tool coverage is required. **Why:** absent evidence is not evidence of absence.
- Use the current agent and local shell; do not start another runtime or orchestration substrate unless explicitly requested. **Why:** repository scanning is a bounded operation, not permission to fan out.
- Report findings and coverage gaps, then stop. Remediation, risk acceptance,
  reruns, promotion, and any ship or merge call are caller decisions. Asked
  whether to ship, merge or deploy, give the findings and coverage, then say in
  one line that the go/no-go on that evidence is the caller's; recommending
  ship, hold or block in any wording is that decision. Name each finding's
  remediation class in a few words; do not write the patch, a plan, an owner,
  or a priority.

## What every review reports

Apply these to every review, scripted or manual. They are the rules most often skipped:

1. **Fail-open paths.** For every guard, check, timeout, and exception handler
   on the surface, ask what happens when it errors or hangs. A control that
   grants access, skips a check, or continues as success on error is a finding
   even when its happy path is correct.
2. **Borrowed identity.** Trace the effective identity at each hop (user,
   service, token, default, hook). A hop where identity is assumed, defaulted,
   or inherited instead of verified is the **borrowed identity** failure mode
   and a finding.
3. **Per-class coverage ledger.** Walk every applicable class in
   [the class checklist](references/owasp-checklist.md), plus fail-open,
```
