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 5.1 | $0.00058 | $0.00673 |
| Opus 5 | $0.00029 | $0.00336 |
| Sonnet 5 | $0.00012 | $0.00135 |
| Haiku 4.5 | $0.00006 | $0.00067 |
Grade A, and why
Secret Scanning and Management 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.

Secret Scanning and Management
Overview
This skill focuses on detecting, managing, and preventing the leakage of sensitive information such as API keys, passwords, tokens, and certificates within the codebase and version control history.
Core Principles
1. No Hardcoded Secrets
Source code should never contain sensitive data.
- Separation of code and config: Store configuration (including secrets) in the environment, separate from the application code (as per 12-Factor App principles).
- Environment Variables: Use
.envfiles for local development but ensure they are strictly ignored in version control (.gitignore).
2. Secret Scanning
Actively scan the repository for accidentally committed secrets.
- CI/CD Integration: Integrate tools like TruffleHog, Gitleaks, or GitHub Advanced Security into your CI pipeline to scan commits before they are merged.
- Historical Scanning: Scan the entire git history, not just the current state of the code, because deleted secrets in previous commits are still compromised.
3. Pre-commit Hooks
Prevent secrets from ever entering the git history.
- Client-side checks: Set up tools like
pre-committo run secret scanners locally before a developer can successfully commit code.
4. Secret Managers
Use dedicated systems to store and inject secrets at runtime.
- Centralized Management: Use solutions like AWS Secrets Manager, HashiCorp Vault, Azure Key Vault, or Google Secret Manager.
- Dynamic Secrets: Where possible, prefer short-lived, dynamically generated credentials over long-lived static keys.
5. Remediation
If a secret is leaked, it must be considered compromised immediately.
- Revoke and Rotate: Never just delete the secret from the code. You must revoke the leaked key at the provider and generate a new one.
Code Examples
Setting up a Pre-commit Hook for Gitleaks
Create a .pre-commit-config.yaml in your repository root:
repos:
- repo: https://github.com/zricethezav/gitleaks
rev: v8.18.1
hooks:
- id: gitleaks
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.

Secret Scanning and Management is a skill published in the GitHub repository GktuOktay/ai-skills (2 stars, last pushed 9d ago), licensed MIT. It adds 58 tokens to every session and 673 once invoked, about $0.0003 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 2026-08-31.
