static-application-security-testing

static-application-security-testing is a skill for Claude Code, Codex from h4vzz/awesome-ai-agent-skills. It costs 27 tokens per session (2,090 once invoked), scanned A, a copy of static-application-security-testing, MIT.

A source-code security checker that looks for vulnerabilities without running the application. It uses analysis tools and custom rules for different programming languages.

In plain words
What is it for?
Use it to scan repositories for issues such as SQL injection, cross-site scripting, hardcoded secrets, unsafe deserialization, and cryptographic misuse.
Why use it?
It finds security mistakes early, before they reach users or production. It also helps sort genuine problems from false alarms and connect scans to CI/CD, the automated build and testing process.

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

static-application-security-testing 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.

Static Application Security Testing

This skill enables the agent to perform Static Application Security Testing (SAST) on source code repositories to detect security vulnerabilities without executing the application. The agent selects appropriate analysis tools based on the project's language, runs scans with relevant rule sets, triages findings to separate true positives from false positives, and integrates results into CI/CD pipelines. SAST catches issues such as SQL injection, cross-site scripting, hardcoded secrets, insecure deserialization, and cryptographic misuse early in the development lifecycle.

Workflow

  1. Detect Languages and Frameworks — Analyze the repository to determine primary languages (Python, JavaScript, Java, Go, C#, etc.) and frameworks in use. This determines which SAST tools and rule sets are applicable. Check for existing tool configurations like .semgrep.yml, codeql query packs, or .bandit config files.

  2. Select and Configure SAST Tools — Choose the appropriate tools for the detected stack. Use Semgrep for multi-language pattern matching, CodeQL for deep semantic analysis, Bandit for Python-specific checks, and ESLint security plugins for JavaScript/TypeScript. Load built-in security rule sets and any project-specific custom rules.

  3. Execute Static Analysis — Run the selected tools against the codebase. Capture all findings including the vulnerability type, affected file and line number, severity level, CWE identifier, and a description of the issue. For large codebases, parallelize scans across multiple tools simultaneously.

  4. Triage and Deduplicate Findings — Merge results from multiple tools, remove duplicate detections of the same issue, and classify findings as true positive, false positive, or needs-review. Use contextual analysis such as checking whether a flagged SQL string actually reaches a database driver to reduce noise.

  5. Generate Report with Fix Suggestions — Produce a structured findings report grouped by severity and category. Include the vulnerable code snippet, an explanation of the risk, a suggested fix with corrected code, and references to relevant CWE entries and OWASP categories.
