dev-dependency-management

dev-dependency-management is a skill for Codex from vasilyu1983/AI-Agents-public. It costs 39 tokens per session (2,645 once invoked), scanned A, original, MIT.

A guide to managing software dependencies, the external libraries and tools a project relies on. It covers package managers, lockfiles, updates, security checks, software bills of materials, and monorepos, which are repositories containing multiple related projects.

In plain words
What is it for?
Use it to choose package managers, define lockfile and update policies, manage dependencies in monorepos, scan for vulnerabilities, and create dependency inventories.
Why use it?
It helps keep installs reproducible, updates controlled, and third-party code easier to audit for security and compatibility problems.

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Rogue Agent · line 76
    Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.
    Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.
  • medium Excessive Agency · line 139
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

dev-dependency-management 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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/dep_auditor.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Dependency Management

Use this skill for package-manager choice, lockfile policy, update strategy, supply-chain controls, and dependency hygiene across common ecosystems. It owns reproducibility and security defaults, not framework-specific app architecture.

When to Use

  • Choose or migrate a package manager.
  • Define lockfile, wrapper, or toolchain pinning policy.
  • Add, remove, pin, or upgrade dependencies safely.
  • Resolve dependency conflicts or transitive-risk issues.
  • Set up audits, SBOM generation, provenance checks, or update automation.
  • Define dependency policy for monorepos or polyglot repos.

Route Elsewhere

  • Framework-specific frontend or backend implementation: use the relevant software skill.
  • AppSec architecture beyond the dependency layer: use software-security-appsec.
  • CI/CD platform design: use ops-devops-platform.

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.
