performing-sca-dependency-scanning-with-snykThis skill covers implementing Software Composition Analysis (SCA) using Snyk to detect vulnerable open-source dependencies in CI/CD pipelines.
Performing Sca Dependency Scanning With Snyk is an agent skill from mukul975/Anthropic-Cybersecurity-Skills. This skill covers implementing Software Composition Analysis (SCA) using Snyk to detect vulnerable open-source dependencies in CI/CD pipelines. It addresses scanning package manifests and lockfiles, automated fix pull request generation, license compliance checking, continuous monitoring of deployed applications, and integration with GitHub, GitLab, and Jenkins pipelines.
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts, reference files and assets (for example `assets/template.md`, `references/api-reference.md` and `references/standards.md`).
It sits in Legal & Compliance, covering Regulatory compliance, Pull requests and CI/CD. It works with Snyk, GitHub, GitLab and Jenkins. The repository describes itself as: 817 structured cybersecurity skills for AI agents · Mapped to 6 frameworks: MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, NIST AI RMF & MITRE F3 (Fight Fraud) · agentskills.io…. The licence is Apache-2.0.
6 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships 2 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
jqnpmFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
SNYK_TOKENFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Performing Sca Dependency Scanning With Snyk loads about 2.2k tokens when it runs, and up to ~4.5k if it reads all its reference files. Until then it costs about 105 tokens; SKILL.md has 525 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

|---|---|
| SCA | Software Composition Analysis — identifies vulnerabilities and license risks in open-source dependencies |
| Transitive Dependency | A dependency of a direct dependency, often invisible to developers but still a vulnerability vector |
| Fix PR | Automated pull request generated by Snyk that upgrades a vulnerable dependency to a patched version |
| Snyk Monitor | Continuous monitoring mode that watches deployed projects for newly disclosed vulnerabilities |
| Exploit Maturity | Snyk's assessment of whether a vulnerability has known exploits, proof-of-concept, or no known exploit |
| Reachable Vulnerability | A vulnerability in a function that is actually called by the application code, not just present in the dependency |
| License Policy | Organization-level rules defining which open-source licenses are approved, restricted, or require review |
Context: Snyk reports a critical RCE vulnerability in a transitive dependency (log4j in a Java application). The direct dependency has not released a patch.
Approach:
snyk test --json and examine the dependency path to identify which direct dependency pulls in the vulnerable transitive<dependencyManagement> section to force the safe version of the transitive dependencyoverrides section in package.json to pin the safe versionPitfalls: Ignoring transitive vulnerabilities because "we don't use that function directly" is risky. Attackers can chain vulnerabilities across dependency boundaries. Version overrides can break API compatibility between the direct and transitive dependency.

Going by SKILL.md and its folder, Performing Sca Dependency Scanning With Snyk needs Python for the scripts in its folder, the command-line tools its instructions call (jq and npm) and credentials named SNYK_TOKEN. Our summary lists: Python 3; Node.js; Docker; A credential in SNYK_TOKEN.
SKILL.md contains no URLs. Its commands use npm, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Performing Sca Dependency Scanning With Snyk is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.2k tokens (SKILL.md is roughly 8.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2.2k tokens, read only when the agent opens those files.
