Static application security testing (SAST) for changed source files — Vulnetix''s built-in rule set plus optional Semgrep augmentation when `.semgrep` config is present. Use when reviewing a PR for code-level vulnerabilities, scanning a feature branch before merge, gating CI on critical findings, or running rule-specific checks for a known weakness class.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Vulnetix SAST Skill

## Use when

- Pre-commit / pre-merge: scan changed source files for SAST findings.
- Targeted rule check: "did we just write an XXE pattern?" via `--rule-id VNX-XXE-001`.
- CI gate: exit non-zero if SAST finds critical-severity issues.
- Audit a specific weakness class with `--paths <dir> --rule-id VNX-CWE-89-*`.
- Augment Vulnetix's rules with the repo's own Semgrep policy.

## Don't use for

- Dependency vulnerability scanning — use `vulnetix scan --sca`.
- Secret detection — use `secret-scan`.
- Container/IaC scanning — use `container-scan` / `iac-scan`.

## Conventions

Follows `skills/_lib/contract.md`. In short: use the `vulnetix_*` MCP tools when the agent has them and the CLI otherwise — both shape their own output, so there is no jq step any more. Independent calls go out as concurrent Bash tool calls in one message. One trailing suggestion, not a playbook. See the contract for surface selection, output style and memory writes.

Static analysis on source code. Capability-aware: optionally augmented with the user's own Semgrep rules.

## Step 1: Load capabilities

Read `.vulnetix/capabilities.yaml`. Note `binaries.semgrep`, `repo.semgrep_config`.

How to install

The exact contents, by fingerprint
mdr add vulnetix/pix-ai-coding-assistant/sast-scan@sha256:4b65561bc94fb78f

The line at the top of this page pins the label git:20260904.974b690, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
