Configures and runs Semgrep - pattern-based SAST across 30+ languages with the Semgrep Registry rulesets (`p/owasp-top-ten`, `p/default`, `auto`) plus custom YAML rules; integrates `semgrep ci` for PR-blocking gates with `--baseline-commit` diff-aware scanning, per-finding inline `nosemgrep` suppressions, `--exclude` / `--include` path filters, output formats (`--json` / `--sarif` / `--gitlab-sast` / `--junit-xml`), and severity filter (INFO/WARNING/ERROR). Use when the user runs Semgrep, asks about pattern rules, or needs a low-friction SAST gate without semantic-DB setup.

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
The runtime workflow runs `semgrep scan --config auto` / `semgrep ci` which “auto-fetch[es] rules from registry based on project,” meaning attacker-controlled rule text from the Semgrep Registry can be ingested when the outsider can influence which rulesets are fetched or which project triggers them.
