security-analysis

security-analysis is a skill for Claude Code from Abilityai/abilities. It costs 33 tokens per session (588 once invoked), scanned A, original, MIT.

A code security audit based on the OWASP Top 10, a standard list of common web-application risks.

In plain words
What is it for?
It reviews backend and frontend code, records findings with severity levels, and creates a security report.
Why use it?
It helps reveal vulnerabilities in authentication, APIs, database access, token handling, and other code before release.

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.

Fable 5.1 $0.00033 $0.00588
Opus 5.5 $0.00013 $0.00235

Security

Grade A, and why

security-analysis 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 1mo 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.

What it actually says

Security Analysis

ℹ️ First, set expectations: before anything else, print one short line with this skill's version and its most recent change — the top entry of metadata.changelog above — e.g. security-analysis vX.Y — recent: <summary>. Then proceed.

Perform a comprehensive security analysis of the codebase based on OWASP Top 10.

State Dependencies

Source Location Read Write Description
Architecture docs/memory/architecture.md ✅ Security boundaries
Backend Code src/backend/ ✅ API security
Frontend Code src/frontend/ ✅ Client security
Security Report docs/security-reports/security-analysis-{date}.md ✅ Generated report

Scope

$ARGUMENTS

If no scope specified, analyze the full codebase with focus on:

  • src/backend/ - API endpoints, authentication, database access
  • src/frontend/ - Client-side security, token handling

Analysis Process

Follow the methodology in the security-analyzer agent:

  1. Read architecture.md to understand security boundaries
  2. Check each OWASP category systematically
  3. Document findings with severity levels
  4. Generate report to docs/security-reports/

OWASP Categories to Check

  • A01: Broken Access Control
  • A02: Cryptographic Failures
  • A03: Injection
  • A04: Insecure Design
  • A05: Security Misconfiguration
  • A07: Authentication Failures
  • A09: Security Logging Failures

Output

Save report to: docs/security-reports/security-analysis-{date}.md

Return a summary with:

  • Critical/High findings count
  • Top 3 most urgent issues
  • Recommended immediate actions

Completion Checklist

  • Architecture.md reviewed for security boundaries
  • OWASP categories checked systematically
  • Findings documented with severity levels
  • Report saved to docs/security-reports/
  • Summary returned with critical count and top issues

What this file has done since we first saw it

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.

security-analysis is a skill published in the GitHub repository Abilityai/abilities (12 stars, last pushed 3d ago), licensed MIT. It adds 33 tokens to every session and 588 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-07.
