- # Context Engineering
-
- ## Overview
-
- Context management methodology adapted from the Everything Claude Code project. Optimizes context window usage through dynamic injection, mode switching, selective loading, and strategic compaction.
-
- ## Context Modes
-
- ### Dev Mode
+ graph:
+ domains: [domain:software-engineering]
+ skillAreas: [skill-area:agentic-loops, skill-area:orchestration-loop]
+ workflows: [workflow:feature-development]
+ topics: [topic:developer-experience]
+ roles: [role:tech-lead, role:backend-engineer]
- Load: architecture docs, active code files, test files, recent changes
- Skip: historical discussions, completed milestones, research notes
- Priority: implementation speed
### Review Mode
- Load: code diff, coding standards, security rules, test coverage
- Skip: architecture docs, planning notes, research
- Priority: thoroughness and accuracy
### Research Mode
- Load: requirements, existing patterns, external research, alternatives
- Skip: implementation details, test files, CI configs
- Priority: breadth of information
## Dynamic Injection
- Detect project context automatically (language, framework, tools)
- Load relevant skills based on detected context
- Inject domain-specific patterns and conventions
- Adjust tool allowlists per context mode
## Selective Loading
- Load only files relevant to the current task
- Use glob patterns to scope file reading
- Prioritize recently modified files
- Skip binary files and generated code
## Strategic Compaction
- Monitor context token usage
- Suggest compression for resolved/completed items
- Archive to memory files (activeContext, patterns, progress)
- Pre-compaction state preservation
- Automated compaction triggers at token thresholds
## Cross-Platform Detection
- Package manager: npm (package-lock.json), pnpm (pnpm-lock.yaml), yarn (yarn.lock), bun (bun.lockb)
- Language: TypeScript (tsconfig.json), Go (go.mod), Python (pyproject.toml), Java (pom.xml)
- Test runner: vitest, jest, pytest, go test
- CI/CD: GitHub Actions, Dockerfile, docker-compose
## When to Use
- Session initialization (detect context)
- Before each phase (inject relevant context)
- Token budget warnings (strategic compaction)
- Mode transitions (dev to review to research)
## Agents Used
- Used by all agents indirectly through context detection
- `context-engineering` agent for explicit compaction analysis
