pattern-exhaustion

pattern-exhaustion is a skill for Claude Code, Codex from MingyiSecLab/Mingyi-Atlas. It costs 33 tokens per session (1,311 once invoked), scanned A, original, Apache-2.0.

A security-testing method for finding every instance of the same vulnerability pattern after one problem has been confirmed. A vulnerability is a weakness that can let someone misuse software.

In plain words
What is it for?
Use it to search a codebase for repeated missing permission checks, unsafe path handling, SQL built from strings, and other matching root causes.
Why use it?
Finding one flaw may reveal a wider design mistake, so checking only the original location can leave similar weaknesses unfixed elsewhere.

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

pattern-exhaustion 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 12d 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.

The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pattern Exhaustion

When you find a vulnerability, you have found a PATTERN. The same developer who wrote one broken auth check likely wrote twenty. The same framework that misses one guard has a systemic design gap. One root cause → multiple CVEs.

Real-world examples:

  • Parse Server: 4 advisories from guard bypass patterns (prototype chain, falsy-value guard, protected-field bypass, complexity validator)
  • zrok: 3 advisories from access control (symlink traversal, broken ownership, reflected XSS in callback)
  • AVideo: 3 advisories from deployment config (SSRF, exposed installer, memcached session leak)

The Exhaustion Loop

1. Classify the root cause

After confirming a vulnerability, classify its root cause pattern:

Root Cause Search Pattern
Missing auth/authz check grep -rn 'def handle_|router\.\(get|post|put|delete\)' | grep -v 'auth|permission|require|middleware'
Unvalidated path parameter grep -rn 'req\.params|request\.args|ctx\.params' | grep -v 'sanitize|validate|path\.resolve|path\.normalize'
SQL string interpolation grep -rn 'f"SELECT|f"INSERT|f"UPDATE|query(.*\+.*|query(.*\$\{' --include='*.py' --include='*.ts' --include='*.js'
shell: true with user input grep -rn 'shell:\s*true|shell=True|os\.system|subprocess\.call.*shell' --include='*.py' --include='*.ts' --include='*.js'
Missing ownership validation grep -rn 'delete|update|modify' --include='*.py' --include='*.ts' | grep -v 'owner|author|created_by|user_id.*=='

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.

pattern-exhaustion is a skill published in the GitHub repository MingyiSecLab/Mingyi-Atlas (11 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 33 tokens to every session and 1,311 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
