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.

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 | $0.00069 | $0.01684 |
| Opus 5 | $0.00034 | $0.00842 |
| Sonnet 5 | $0.00014 | $0.00337 |
| Haiku 4.5 | $0.00007 | $0.00168 |
Grade A, and why
sast-report scanned grade A with 1 finding 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 11d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts
The opening of the file, as written. The whole thing — 211 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Final Security Report Generation
You are consolidating all completed SAST vulnerability scan results into a single prioritized security report.
Prerequisites: At least one sast/*-results.md file must exist. Run the vulnerability detection skills first if they don't.
What to Include
Only include findings with these classifications from each result file:
[VULNERABLE][LIKELY VULNERABLE]
Exclude [NOT VULNERABLE] and [NEEDS MANUAL REVIEW] findings from the main report body (count them only in the summary).
Severity Ranking
Assign each finding a severity tier — Critical, High, Medium, or Low — using the table below as your baseline. Adjust up or down based on context (e.g., an IDOR that exposes financial records is High, not Medium).
| Vulnerability Class | Default Severity |
|---|---|
| RCE via command injection, eval, or unsafe deserialization | Critical |
| SSTI (Server-Side Template Injection) | Critical |
| SQLi on authentication endpoints | Critical |
| JWT algorithm confusion (alg:none, RS256→HS256) | Critical |
| File upload leading to code execution (webshell) | Critical |
| SQLi with full data extraction capability | High–Critical |
| GraphQL injection (user-controlled operation document enabling unauthorized fields or gateway abuse) | High–Critical |
| XXE with file read or internal SSRF | High–Critical |
| Missing authentication on sensitive endpoints | High–Critical |
| SSRF reaching internal services or cloud metadata | High |
| Path traversal reading sensitive or config files | High |
| File upload with stored content accessible to others | High |
| IDOR on PII, financial, or health data | High |
| XSS (stored/persistent) | High |
| JWT with missing or bypassable claim validation | Medium–High |
| Missing authentication on lower-sensitivity endpoints | Medium |
| IDOR on non-sensitive data | Medium |
| XSS (reflected or DOM) | Medium |
| Business logic flaws (price manipulation, workflow bypass) | Medium |
| Information disclosure of non-sensitive data | Low |
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-report is a skill published in the GitHub repository utkusen/sast-skills (1,307 stars, last pushed 5mo ago), licensed MIT. It adds 69 tokens to every session and 1,684 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
