dependency-audit-nodeclient

A security review for Go modules and Rust crates used by a Node client. It checks dependencies, versions, known vulnerabilities, supply-chain concerns, and replacement rules.

In plain words
What is it for?
Use it when reviewing a codebase with Go or Rust dependencies, especially a client that connects to another service or protocol.
Why use it?
It helps find risky or outdated libraries and makes unusual dependency replacements visible. This reduces the chance of trusting an unsafe package or fork.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

dependency-audit-nodeclient 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 3d 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.

Injectable Skill: Node Client Dependency Audit

L1 trigger: L1_PATTERN=true — always runs Inject Into: Recon + any breadth agent Finding prefix: [DEP-N] Status: v0.1 draft, Round 4 exemplars pending

When This Skill Activates

Always active in L1 mode. Extends Plamen's existing dependency-audit skill with Go/Rust-specific checks relevant to node clients.

1. Go Module Audit

1a. Version check

  • Read go.mod — identify every require line
  • Check against Go vulnerability database: govulncheck ./... (ships with Go 1.18+)
  • Check against OSV: https://osv.dev/
  • Check against GitHub advisories for each dep

1b. Replace directive audit

  • replace directives in go.mod can redirect a dep to a fork or local path
  • Every replace is a trust statement: the audit must identify what's being replaced with what, and whether the replacement is authentic
  • Fork audits: the target likely has replace pointing to the parent client (e.g., replace github.com/ethereum/go-ethereum => github.com/ethereum-optimism/op-geth v1.x.y)
  • Flag every replace with an explicit note in the finding

Tag: [GO-REPLACE:{original}:{replacement}:{trust-note}]

1c. vendor/ directory

  • If the target uses vendor/, check if vendored code matches upstream. Modified vendored deps are a red flag.
  • Run go mod verify if possible to check checksums

Tag: [GO-VENDOR-DIFF:{module}]

1d. Indirect dependency bloat

  • Excessive transitive deps increase the attack surface
  • For each // indirect line, ask: is the intermediate dep actually used?

2. Rust Cargo Audit

2a. Version check

  • cargo audit (requires the cargo-audit tool; install with cargo install cargo-audit)
  • Reads Cargo.lock against the RustSec advisory database (https://rustsec.org/)
  • cargo deny for richer policy (denylist, license, trust)

2b. Patch directive audit

  • [patch.crates-io] and [patch."https://..."] blocks in Cargo.toml and workspace root
  • Same trust concern as Go replace: patches redirect deps
  • Fork audits: likely patches pointing to parent client

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-nodeclient is a skill published in the GitHub repository PlamenTSV/plamen (281 stars, last pushed 1mo ago), licensed MIT. It adds 33 tokens to every session and 1,926 once invoked, about $0.0002 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 2026-08-30.
