dependency-checker

dependency-checker is a skill for Claude Code, Codex from sequenzia/agent-alchemy. It costs 20 tokens per session (6,365 once invoked), scanned A, original, MIT.

A health checker for the Agent Alchemy plugin ecosystem, which is a collection of related coding-agent extensions.

In plain words
What is it for?
It checks dependencies, file paths, unused components, and differences between documentation and the actual plugins, then produces a severity-ranked report.
Why use it?
It finds broken connections and outdated documentation that can make plugins fail or become difficult to maintain.

Skill for Claude CodeCodex

Installs and runs on its own, but its text points at files inside the plugin that ships it — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed.

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-checker 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 4d 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.

Dependency Checker

Analyze the Agent Alchemy plugin ecosystem to detect dependency issues, broken paths, orphaned components, and documentation drift. Produces a health report with severity-ranked findings.

CRITICAL: Complete ALL 5 phases. The workflow is not complete until Phase 5: Report is finished. After completing each phase, immediately proceed to the next phase without waiting for user prompts.

Critical Rules

AskUserQuestion is MANDATORY

IMPORTANT: You MUST use the AskUserQuestion tool for ALL questions to the user. Never ask questions through regular text output.

  • Report presentation -> AskUserQuestion
  • Action selection -> AskUserQuestion
  • View mode selection -> AskUserQuestion

Text output should only be used for:

  • Displaying progress updates between phases
  • Presenting intermediate analysis summaries (inventory counts, graph stats)
  • Phase transition markers

If you need the user to make a choice or provide input, use AskUserQuestion.

NEVER do this (asking via text output):

Would you like to view findings by severity or by plugin group?
1. By severity
2. By plugin group

ALWAYS do this (using AskUserQuestion tool):

AskUserQuestion:
  questions:
    - header: "View Mode"
      question: "How would you like to view the findings?"
      options:
        - label: "By severity"
          description: "Group findings from critical to low"
        - label: "By plugin group"
          description: "Filter findings to a specific plugin group"
      multiSelect: false

Plan Mode Behavior

CRITICAL: This skill performs an interactive analysis workflow, NOT an implementation plan. When invoked during Claude Code's plan mode:

  • DO NOT create an implementation plan for how to build the analysis
  • DO NOT defer analysis to an "execution phase"
  • DO proceed with the full analysis workflow immediately
  • DO write report files as normal if --report-file is specified

Phase Overview

Execute these phases in order, completing ALL of them:

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.
