dev-guide-security-audit

dev-guide-security-audit is a skill for Claude Code, Codex from Lingtai-AI/lingtai. It costs 42 tokens per session (3,520 once invoked), scanned A, original, Apache-2.0.

A read-only checklist for security audits of a LingTai development environment, including secrets, permissions, MCP settings, data exposure, and agent access.

In plain words
What is it for?
Use it to scan a specified directory, classify findings by severity, and produce a redacted security report.
Why use it?
It helps find possible security problems while preventing the audit itself from exposing secret values or changing files.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

dev-guide-security-audit 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 10d 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.

LingTai Security Audit Reference

Nested lingtai-dev-guide reference. Read this after the top-level router sends you here.

Read the lingtai-kernel-anatomy skill first to understand the architecture. This document audits against the LingTai filesystem layout, process model, and communication mechanisms.


Core Principle

This audit framework is strictly read-only. Scan, report, recommend — but never modify any files. All fixes must be performed manually by authorized personnel with appropriate permissions.

Two rules bind every dimension below: pattern matching produces false positives, so every hit needs manual verification; and the report must never contain an actual secret value — report "match found" with the value replaced by <REDACTED>, or the report itself becomes the leak.

Each dimension is scoped to a scan_dir:

scan_dir="<network-dir>"

Audit Dimensions

1. Secret Leak Pattern Scan

Detects API keys, tokens, and credentials exposed in the network directory — .env files committed during development, MCP configurations with keys written inline instead of referencing environment variables, and debug logs that captured full authentication headers.

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.

dev-guide-security-audit is a skill published in the GitHub repository Lingtai-AI/lingtai (670 stars, last pushed yesterday), licensed Apache-2.0. It adds 42 tokens to every session and 3,520 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.
