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 | $0.00164 | $0.07692 |
| Opus 5.5 | $0.00066 | $0.03077 |
| Sonnet 5.5 | $0.00033 | $0.01538 |
| Haiku 4.5 | $0.00016 | $0.00769 |
Grade B, and why
dependency-audit scanned grade B with 3 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 today.
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.
Downloads and executes remote codemediumSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
| 6 | Checksum or signature fetched from the same origin as the artifact; `curl \| sh` | `grep -rnE "(curl\|wget).*(\.sha256\|checksums\|\.sig\|\.asc)"` and `grep -rnE "(curl\|wget)[^\|]*\|\s*(ba)?sh"` | Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Reads MCP configurationlowAgent snooping
mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.
grep -nE '"docker"' -A8 .mcp.json .cursor/mcp.json 2>/dev/null | grep -vE ':[0-9][^"]*"|@sha256:' Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 423 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Dependency Audit — Framework, Package, and Toolchain Security
Audit project dependencies, frameworks, language runtimes, and dev tools for known vulnerabilities (CVEs), security anti-patterns, and supply chain risks.
Cross-references: patch-sweep for patching the same advisory across many repos; scanner-pipeline for running osv-scanner / trivy in CI across every lockfile at once; agent-supply-chain-audit for reviewing the content of MCP servers, skills, and plugins this skill inventories; cloud-audit "PaaS" for platform runtime and config checks behind Mitigated (platform/config); secrets-audit for tokens found in .npmrc or CI; iam-audit for the cloud roles CI assumes via OIDC; finding-triage for dispositioning individual findings.
Authorization
Confirm the user owns or is authorized to audit the repo, CI system, and registries before running anything. Audit tools are read-only, but fix commands (audit fix, bundle update) rewrite lockfiles. Run them only when asked, on a branch, never on the production branch directly.
Methodology
Step 0: Confirm What Ships
Before inventorying anything, confirm you are auditing the code that is actually deployed:
- Production branch: the branch the platform or deploy workflow builds from (Vercel/Netlify production branch, Heroku pipeline,
on: push: branches:in the deploy workflow). It is not alwaysmain. In one field sweep,mainheld only a README. - Monorepos: which app or package is deployed, and its lockfile or workspace slice.
- Package manager: which lockfile is committed and the
packageManagerfield. This decides the audit command in Step 2.
If the deployed branch can't be confirmed from the repo, say which branch you audited and mark it needs_validation. Details: references/fixing-safely.md §10.
Step 1: Inventory the Stack
Identify everything in use — not just direct dependencies but the full chain:
Package manifests — read and catalog:
Node/JS: package.json, package-lock.json, yarn.lock, pnpm-lock.yaml
Python: requirements.txt, Pipfile.lock, pyproject.toml, poetry.lock
Ruby: Gemfile, Gemfile.lock
Go: go.mod, go.sum
Rust: Cargo.toml, Cargo.lock
Java: pom.xml, build.gradle
PHP: composer.json, composer.lock
.NET: *.csproj, packages.config
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-audit is a cursor rule published in the GitHub repository briiirussell/cybersecurity-skills (435 stars, last pushed today), licensed MIT. It adds 164 tokens to every session and 7,692 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it B with 3 findings (downloads and executes remote code, reads mcp configuration, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
