What it does

Dependency Analysis is an agent skill from revfactory/harness-100. Tools and methodologies for analyzing codebase dependency graphs and quantitatively measuring coupling/cohesion. Use this skill for 'dependency analysis', 'coupling measurement', 'circular dependencies', 'module coupling', 'cohesion analysis', 'dependency graph', 'coupling analysis', and other code dependency-related analysis. Enhances the dependency analysis capabilities of legacy-analyzer and refactoring-strategist. Note: full pipeline orchestration is outside the scope of this skill.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Data pipelines and ETL and Refactoring. The licence is Apache-2.0.

When your agent uses it

Dependency analysis
Coupling measurement
Circular dependencies
Module coupling

Example prompts

“dependency analysis”
“coupling measurement”
“circular dependencies”
“/dependency-analysis”

Requirements

Python 3
Node.js

Workflow steps

4 steps, taken from the step headings in SKILL.md.

What it can do on your machine

Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Dependency Analysis loads about 1.2k tokens when it runs. Until then it costs about 128 tokens; SKILL.md has 186 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~128
When it runs · the whole SKILL.md, loaded when a task matches: ~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Dependency Analysis — Dependency Graph Analysis Tool

Methodologies and tool guide for quantitative measurement and visualization of code dependencies.

Dependency Metric System

1. Coupling Metrics

Metric	Formula	Interpretation	Risk Threshold
Ca (Afferent Coupling)	Number of packages depending on me	High = large change ripple effect	> 20
Ce (Efferent Coupling)	Number of packages I depend on	High = unstable	> 20
I (Instability)	Ce / (Ca + Ce)	0=stable, 1=unstable	Warning in middle zone (0.3-0.7)
D (Distance)	\|A + I - 1\|	Distance from the main sequence	> 0.3

Stable Dependencies Principle (SDP) Verification:

Dependency direction: Unstable -> Stable (correct)
Violation: Stable -> Unstable (risky — dependency inversion needed)

2. Cohesion Metrics

Metric	Measurement Target	Acceptable Threshold
LCOM4	Number of connected components within a class	= 1
TCC (Tight Class Cohesion)	Ratio of directly connected methods	> 0.5
H (Henderson-Sellers)	Ratio of intra-package relationships	> 0.7

3. Circular Dependency Detection — Tarjan SCC Algorithm

python

def find_cycles(graph):
    """Detect circular dependency groups using Tarjan SCC"""
    index_counter, stack, result = [0], [], []
    lowlink, index, on_stack = {}, {}, {}

    def strongconnect(v):
        index[v] = lowlink[v] = index_counter[0]
        index_counter[0] += 1
        on_stack[v] = True
        stack.append(v)
        for w in graph.get(v, []):
            if w not in index:
                strongconnect(w)
                lowlink[v] = min(lowlink[v], lowlink[w])
            elif on_stack.get(w):
                lowlink[v] = min(lowlink[v], index[w])
        if lowlink[v] == index[v]:
            component = set()
            while True:
                w = stack.pop()
                on_stack[w] = False
                component.add(w)
                if w == v: break
            if len(component) > 1:
                result.append(component)
    for v in graph:
        if v not in index: strongconnect(v)
    return result

4. Cycle Resolution Patterns

Pattern	Applicable Situation	Method
Dependency Inversion (DIP)	A<->B bidirectional	Extract interface, unify direction
Event-based Decoupling	A->B->A callback	Indirect communication via event bus
Mediator Pattern	A<->B<->C complex cycle	Central coordination via Mediator
Common Module Extraction	A<->B shared logic	Extract shared parts into module C

Language-specific Tools

JavaScript/TypeScript

bash

npx madge --image graph.svg src/        # Dependency graph
npx madge --circular src/               # Circular detection
npx depcheck                            # Unused dependencies

Python

bash

pipdeptree --graph-output svg > deps.svg
pydeps src/mypackage --max-bacon=2

Java/Kotlin

bash

./gradlew dependencies --configuration runtimeClasspath
# Architecture rule testing with ArchUnit

Change Impact Analysis (CIA)

Changed file: UserService.java
+-- Direct impact (depth 1): UserController, OrderService, AuthService
+-- Indirect impact (depth 2): OrderController, PaymentService
+-- Test impact: UserServiceTest, OrderIntegrationTest
-> Estimated ripple scope: 8 files, 3 tests

Architecture Fitness Functions

python

DEPENDENCY_RULES = {
    "domain -> infrastructure prohibited": {
        "from": "domain/**", "to_not": "infrastructure/**", "severity": "ERROR"
    },
    "controller -> repository direct access prohibited": {
        "from": "controller/**", "to_not": "repository/**", "severity": "ERROR"
    },
}

# Dependency Analysis Report

## Summary
- Total modules: N | Average coupling (Ce): X.X | Circular groups: N

## Per-module Metrics
| Module | Ca | Ce | I | A | D | LCOM4 | Grade |

## Circular Dependencies
- Group 1: [A, B, C] — Resolution strategy: DIP

## Hotspots (High Ca + High Ce)
- ModuleX: Ca=25, Ce=18 — Excessive change ripple scope

## Recommendations
1. [Urgent] Resolve circular dependencies
2. [Important] Separate hotspot modules
3. [Improvement] Automate dependency rules in CI
