Code Context Finder

Overview

Find and surface relevant context while coding by combining knowledge graph search with code relationship analysis. Uses smart detection to identify when additional context would be helpful, then retrieves:

• Knowledge graph entities: Prior decisions, project context, related concepts
• Code relationships: Dependencies, imports, function calls, class hierarchies

When to Use (Smart Detection)

This skill activates automatically when detecting:

Trigger	What to Search
Opening unfamiliar file	Knowledge graph for file/module context, code for imports/dependencies
Working on new feature	Prior decisions, related concepts, similar implementations
Debugging errors	Related issues, error patterns, affected components
Refactoring code	Dependent files, callers/callees, test coverage
Making architectural decisions	Past ADRs, related design docs, established patterns
Touching config/infra files	Related deployments, environment notes, past issues

For detection triggers reference, load references/detection_triggers.md.

Core Workflow

1. Detect Context Need

Identify triggers that suggest context would help:

Signals to watch:
- New/unfamiliar file opened
- Error messages mentioning unknown components
- Questions about "why" or "how" something works
- Changes to shared/core modules
- Architectural or design discussions

2. Search Knowledge Graph

Use MCP memory tools to find relevant entities:

# Search for related context
mcp__memory__search_nodes(query="<topic>")

# Open specific entities if known
mcp__memory__open_nodes(names=["entity1", "entity2"])

# View relationships
mcp__memory__read_graph()

Search strategies:

• Module/file names → project context
• Error types → past issues, solutions
• Feature names → prior decisions, rationale
• People names → ownership, expertise

3. Analyze Code Relationships

Find code-level context:

# Find what imports this module
grep -r "from module import" --include="*.py"
grep -r "import module" --include="*.py"

# Find function callers
grep -r "function_name(" --include="*.py"

# Find class usages
grep -r "ClassName" --include="*.py"

# Find test coverage
find . -name "*test*.py" -exec grep -l "module_name" {} \;

4. Synthesize Context

Present findings concisely:

## Context Found

**Knowledge Graph:**
- [Entity]: Relevant observation
- [Decision]: Prior architectural choice

**Code Relationships:**
- Imported by: file1.py, file2.py
- Depends on: module_a, module_b
- Tests: test_module.py (5 tests)

**Suggested Actions:**
- Review [entity] before modifying
- Consider impact on [dependent files]

Quick Reference

Knowledge Graph Queries

Intent	Query Pattern
Find project context	search_nodes("project-name")
Find prior decisions	search_nodes("decision") or search_nodes("<feature>")
Find related concepts	search_nodes("<concept>")
Find people/owners	search_nodes("<person-name>")
Browse all	read_graph()

Code Relationship Queries

Intent	Command
Find importers	grep -r "from X import|import X"
Find callers	grep -r "function("
Find implementations	grep -r "def function|class Class"
Find tests	find -name "*test*" -exec grep -l "X"
Find configs	grep -r "X" *.json *.yaml *.toml

Integration with Coding Workflow

Before Making Changes

1. Check knowledge graph for context on module/feature
2. Find all files that import/depend on target
3. Locate relevant tests
4. Review prior decisions if architectural

After Making Changes

1. Update knowledge graph if significant decision made
2. Note new patterns or learnings
3. Add observations to existing entities

When Debugging

1. Search knowledge graph for similar errors
2. Find all code paths to affected component
3. Check for related issues/decisions
4. Document solution if novel
