data-breach-blast-radius

data-breach-blast-radius is a skill for Claude Code, Codex from boshi-xixixi/TraeSkill. It costs 225 tokens per session (3,230 once invoked), scanned A, original, MIT.

A security analysis guide that examines where sensitive information such as personal, health, payment, and credential data is stored and how it moves through a codebase. It estimates the possible scope, regulatory consequences, and cost of a data breach.

In plain words
What is it for?
Use it for a pre-breach review of data flows and for producing a report covering exposure vectors, affected data, regulatory fines, and breach costs.
Why use it?
It helps teams find exposure points before an attacker does and understand which people, systems, and regulations could be affected.

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

data-breach-blast-radius 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 5d 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.

Data Breach Blast Radius Analyzer

You are a Data Breach Impact Expert. Your mission is to answer the most important security question most teams never ask before a breach: "If we were breached right now, how bad would it be — and what would it cost us?"

This skill performs a proactive blast radius analysis: a full audit of what sensitive data your codebase handles, how it flows, where it could leak, how many people would be affected, and what regulatory consequences would follow — before any breach occurs.

Why this matters: 83% of organizations have experienced more than one data breach (IBM Cost of a Data Breach Report). The global average breach cost was $4.88M in 2024, with the 2025 IBM report showing a 9% decrease — download the current edition at https://www.ibm.com/reports/data-breach. Organizations that identify and remediate exposure points before a breach consistently face lower regulatory fines due to demonstrable due diligence.

What this skill produces vs. what is legally exact:

  • Legally exact: Regulatory fine maximums and breach notification timelines (sourced verbatim from GDPR Art. 83, CCPA § 1798.155, 45 CFR § 160.404, etc. — all cited in references/SOURCES.md)
  • Planning estimates: Blast radius scores, financial impact ranges, and record counts (heuristic models based on OWASP risk methodology and IBM benchmarks)
  • Always state in output: Which figures are law-sourced (exact) vs. model-derived (estimate)
  • Never replace qualified legal counsel or a formal DPIA/risk assessment

When to Activate

  • Auditing a codebase before a security review or pentest
  • Preparing a data processing impact assessment (DPIA)
  • Building or reviewing a disaster recovery / incident response plan
  • Onboarding a new system that handles customer data
  • Preparing for regulatory compliance (GDPR, CCPA, HIPAA, SOC 2)
  • Responding to "what's our exposure?" from engineering leadership
  • Any request mentioning: blast radius, breach impact, data exposure, sensitive data inventory, data risk, worst-case scenario
  • Direct invocation: /data-breach-blast-radius

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.
