Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00048 | $0.01185 |
| Opus 5 | $0.00024 | $0.00593 |
| Sonnet 5 | $0.00010 | $0.00237 |
| Haiku 4.5 | $0.00005 | $0.00119 |
Grade A, and why
insecure-defaults 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 yesterday.
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.
This is a copy
89% identical to insecure-defaults — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Insecure Defaults Detection
Finds fail-open vulnerabilities where apps run insecurely with missing configuration. Distinguishes exploitable defaults from fail-secure patterns that crash safely.
- Fail-open (CRITICAL):
SECRET = env.get('KEY') or 'default'→ App runs with weak secret - Fail-secure (SAFE):
SECRET = env['KEY']→ App crashes if missing
When to Use
- Security audits of production applications (auth, crypto, API security)
- Configuration review of deployment files, IaC templates, Docker configs
- Code review of environment variable handling and secrets management
- Pre-deployment checks for hardcoded credentials or weak defaults
When NOT to Use
Do not use this skill for:
- Test fixtures explicitly scoped to test environments (files in
test/,spec/,__tests__/) - Example/template files (
.example,.template,.samplesuffixes) - Development-only tools (local Docker Compose for dev, debug scripts)
- Documentation examples in README.md or docs/ directories
- Build-time configuration that gets replaced during deployment
- Crash-on-missing behavior where app won't start without proper config (fail-secure)
When in doubt: trace the code path to determine if the app runs with the default or crashes.
Rationalizations to Reject
- "It's just a development default" → If it reaches production code, it's a finding
- "The production config overrides it" → Verify prod config exists; code-level vulnerability remains if not
- "This would never run without proper config" → Prove it with code trace; many apps fail silently
- "It's behind authentication" → Defense in depth; compromised session still exploits weak defaults
- "We'll fix it before release" → Document now; "later" rarely comes
Workflow
Follow this workflow for every potential finding:
1. SEARCH: Perform Project Discovery and Find Insecure Defaults
Determine language, framework, and project conventions. Use this information to further discover things like secret storage locations, secret usage patterns, credentialed third-party integrations, cryptography, and any other relevant configuration. Further use information to analyze insecure default configurations.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

insecure-defaults is a skill published in the GitHub repository CraftOS-dev/CraftBot (378 stars, last pushed 2d ago), licensed MIT. It adds 48 tokens to every session and 1,185 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 89% identical to insecure-defaults, differing in 4 lines, and is treated as a copy.
