dependency-graph

dependency-graph is a skill for Claude Code, Codex from DavidROliverBA/ArchitectKB. It costs 10 tokens per session (2,014 once invoked), scanned A, original, MIT.

A way to map how systems depend on one another and display those relationships as text, ASCII art, Mermaid, or D3. A dependency is a relationship where one system needs another to work.

In plain words
What is it for?
Use it to trace upstream sources or downstream users, inspect a selected number of dependency levels, assess risks, plan maintenance, or prepare disaster-recovery work.
Why use it?
It shows what could be affected by an outage, change, or system removal and helps reveal bottlenecks and single points of failure.

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-graph 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-graph Skill

Visualize system dependencies and identify critical paths, bottlenecks, and single points of failure.

When to Use This Skill

Use /dependency-graph when you need to:

  • Understand what systems depend on a critical system
  • Identify single points of failure
  • Plan outage impact for maintenance
  • Design disaster recovery strategies
  • Perform risk assessment on architecture
  • Plan system decommissioning (understand what breaks)
  • Optimize architecture to reduce critical dependencies

Usage

/dependency-graph [root-system] [options]

Parameters

Parameter Description Required
root-system System to analyze (or "all" for enterprise graph) Optional
--depth How many hops to follow (1=direct, 2=direct+indirect, all) Optional
--direction Direction to follow (upstream=sources, downstream=consumers, both) Optional
--visualization Graph format (text, ascii-art, mermaid, d3) Optional

Workflow

Phase 1: Define Graph Scope

User specifies:

  1. Root system (optional - default: all systems)

    • Single system (system:ERP)
    • All systems (enterprise)
    • Critical systems only
  2. Depth (optional)

    • 1 - Direct dependencies only (immediate consumers/producers)
    • 2 - Direct + indirect (one level deeper)
    • all - All paths to edges (complete dependency closure)
  3. Direction (optional)

    • upstream - What feeds into this system (sources)
    • downstream - What consumes from this system
    • both - Both upstream and downstream (default)
  4. Visualization (optional)

    • text - ASCII text representation
    • ascii-art - Fancy ASCII visualization
    • mermaid - Mermaid diagram (for markdown)
    • d3 - Interactive D3 visualization (HTML)

Phase 2: Analyze Dependencies

The skill:

  1. Builds dependency graph
    • Reads all Integration notes
    • Maps directional relationships
    • Calculates paths and cycles

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-graph is a skill published in the GitHub repository DavidROliverBA/ArchitectKB (52 stars, last pushed 6mo ago), licensed MIT. It adds 10 tokens to every session and 2,014 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.
