dependency-audit

dependency-audit is a skill for Claude Code, Codex from PlamenTSV/plamen. It costs 28 tokens per session (2,397 once invoked), scanned A, original, MIT.

A security-audit skill for third-party Move dependencies, which are external on-chain modules used by Aptos protocols. It reviews their sources, versions, upgrade policies, and dependency chains.

In plain words
What is it for?
Use it to inventory dependencies in Move.toml and assess library security, upgrade risks, critical functions, and transitive dependencies.
Why use it?
It helps identify risks introduced outside the protocol's own code, including changes to dependencies that may alter behavior later. It also checks whether dependency versions are pinned.

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 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 5d 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 — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill: DEPENDENCY_AUDIT

Trigger: EXTERNAL_LIB flag detected (protocol uses third-party Move dependencies) Used by: Breadth agents, depth-external Covers: Third-party library security, upgrade policy risks, critical function correctness, transitive dependency chains

Purpose

Audit third-party Move dependencies for security risks. Aptos protocols commonly depend on external math libraries, utility modules, and protocol SDKs. Unlike EVM (where dependencies are compiled into the contract), Move dependencies are on-chain modules that can be independently upgraded. A dependency upgrade can silently change the behavior of the audited protocol.

Methodology

STEP 1: Dependency Inventory

Parse Move.toml for all dependencies. Categorize each:

# Dependency Source Category Upgrade Policy Revision Pinned?
1 AptosFramework aptos-framework repo FRAMEWORK Framework governance {rev hash or branch}
2 AptosStd aptos-framework repo FRAMEWORK Framework governance {rev hash or branch}
3 AptosToken aptos-framework repo FRAMEWORK Framework governance {rev hash or branch}
4 {third_party_lib} {git URL} THIRD_PARTY {compatible/immutable/unknown} {YES: rev=abc123 / NO: branch=main}
5 {sub_module} local path IN_SCOPE N/A (part of audit) N/A

Categories:

  • FRAMEWORK: aptos_framework, aptos_std, aptos_token, aptos_token_objects - trusted, framework-governance-controlled. Audit framework USAGE, not framework internals.
  • THIRD_PARTY: External libraries (math utils, oracle SDKs, DEX interfaces). MUST audit all called functions.
  • IN_SCOPE: Protocol's own sub-modules. Fully in scope.

MANDATORY PARSE: Read Move.toml (and any sub-package Move.toml files) for:

  1. [dependencies] section entries
  2. git = "..." URLs - identify the source repository
  3. rev = "..." - pinned revision hash (safe) vs branch = "main" (dangerous)
  4. local = "..." - in-scope sub-modules

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 skill published in the GitHub repository PlamenTSV/plamen (281 stars, last pushed 1mo ago), licensed MIT. It adds 28 tokens to every session and 2,397 once invoked, about $0.0001 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.
