SAST Skills is a collection of agent workflows that inspect web and mobile application code for security vulnerabilities, where SAST means static application security testing. Developers and security reviewers use it to map a codebase, verify possible flaws, and produce a severity-ranked remediation report. The catalogue entries are the project's vulnerability-detection and reporting skills.
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.

SkillSpector: 5 findings, up to high
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 →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00124 | $0.06724 |
| Opus 5 | $0.00062 | $0.03362 |
| Sonnet 5 | $0.00025 | $0.01345 |
| Haiku 4.5 | $0.00012 | $0.00672 |
Grade A, and why
sast-hardcodedsecrets 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 409 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hardcoded Secrets in Public Code Detection
You are performing a focused security assessment to find hardcoded sensitive data that is exposed in publicly accessible code. This skill uses a three-phase approach with subagents: recon (find all potential secret candidates), batched verify (confirm each is a real secret in publicly reachable code, in parallel batches of 3), and merge (consolidate batch reports into one file).
Prerequisites: sast/architecture.md must exist. Run the analysis skill first if it doesn't.
What Are Hardcoded Secrets in Public Code
Hardcoded secrets are sensitive credentials — API keys, access tokens, private keys, passwords, signing secrets, database connection strings — embedded directly in source code as string literals.
This skill focuses specifically on secrets that end up in publicly accessible code, meaning an attacker can extract them without any server-side access. A secret hardcoded in backend server code is bad practice but not directly exploitable by an external attacker inspecting the deployed application. A secret hardcoded in frontend JavaScript or a mobile app binary is directly extractable.
The core question: Can an external attacker obtain this secret from the deployed application without server access?
What to Report (Publicly Accessible Code)
These code paths are accessible to attackers after deployment:
- Frontend JavaScript/TypeScript — any
.js,.ts,.jsx,.tsxfile that runs in the browser. This includes:- React, Angular, Vue, Svelte components and pages
- Next.js client components (files with
"use client"or files underapp/without"use server") - Nuxt.js pages and client plugins
- Vanilla JS in
public/,static/, orassets/directories - Webpack/Vite/Rollup entry points and their imported modules
- Any file imported by a client-side entry point (even if it lives in a
utils/orlib/folder)
- Mobile application code — extractable via reverse engineering (decompiling APK, inspecting IPA):
- Android: Java/Kotlin source files
- iOS: Swift/Objective-C source files
- React Native: JavaScript bundles
- Flutter: Dart source files
- Xamarin: C# source files
- HTML files and templates served to clients — inline
<script>blocks,data-attributes, meta tags - Client-side configuration files — files in
public/,static/,assets/,www/directories - Electron/desktop app source — extractable from ASAR archives
- WebAssembly source/companion JS — secrets in JS glue code or extractable from WASM
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.

sast-hardcodedsecrets is a skill published in the GitHub repository utkusen/sast-skills (1,303 stars, last pushed 5mo ago), licensed MIT. It adds 124 tokens to every session and 6,724 once invoked, about $0.0006 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.
