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.

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 | $0.00076 | $0.01218 |
| Opus 5 | $0.00038 | $0.00609 |
| Sonnet 5 | $0.00015 | $0.00244 |
| Haiku 4.5 | $0.00008 | $0.00122 |
Grade A, and why
dependency-vuln-scanner 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Dependency Vulnerability Scanner
Audit project dependencies for security vulnerabilities, supply chain risks, and outdated packages with severity-rated findings and actionable remediation.
Workflow
-
Detect the project's ecosystem(s) Search for dependency manifest files:
package.json→ Node.js/npm/yarn/pnpmrequirements.txtorpyproject.tomlorPipfile→ Pythongo.mod→ GoCargo.toml→ Rustpom.xmlorbuild.gradle→ Java/KotlinGemfile→ Ruby*.csprojorpackages.lock.json→ .NET
Read all found manifests. Note the lock file (package-lock.json, yarn.lock, etc.) existence.
-
Pass 1 — Known CVE Scan Run the ecosystem's built-in audit tool:
- npm:
npm audit --json - pip:
pip-auditorsafety check - cargo:
cargo audit - go:
govulncheck ./... - maven:
mvn dependency-check:check
If the built-in tool is not available, read the manifest and manually cross-reference packages against common CVE databases.
For each vulnerability found:
- Package name and version
- CVE identifier
- CVSS score (Critical ≥9.0, High ≥7.0, Medium ≥4.0, Low <4.0)
- Whether it's in direct or transitive dependency
- Fix available? (patched version, no fix, or workaround)
- npm:
-
Pass 2 — Supply Chain Risk Analysis For each direct dependency, check:
- Maintainer activity: Has the package been updated in the last 12 months?
- Download trends: Is download count declining (potential abandonment)?
- Typosquatting risk: Is the name suspiciously similar to a popular package?
- License compatibility: Are there restrictive licenses (GPL-3.0, AGPL) in an MIT project?
- Dependency depth: Does it pull in a massive transitive tree?
-
Pass 3 — Outdated Packages Run the ecosystem's outdated check:
- npm:
npm outdated --json - pip:
pip list --outdated - cargo:
cargo outdated
Flag packages that are:
- Multiple major versions behind (high risk of breaking changes)
- End-of-life (no longer receiving security patches)
- npm:
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.

dependency-vuln-scanner is a skill published in the GitHub repository sourav15mukherjee/skillforge-free-skills (5 stars, last pushed 5mo ago), licensed MIT. It adds 76 tokens to every session and 1,218 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
