context-engineering is agent-read markdown (skill) from komluk/scaffolding: Optimize Claude Code context-window usage for accuracy and cost. TRIGGER when: hitting context limits, structuring prompts for an agent, or trimming what gets injected into a task. SKIP: persisting knowledge across sessions (use agent-memory); semantic recall tuning (use semantic-memory-mcp)..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Context Engineering Skill
Optimizes Claude Code context for better performance and accuracy.
Tracked files in repo: !`git ls-files 2>/dev/null | wc -l || true`
## Auto-Invoke Triggers
- Every 50 messages in conversation
- After major refactoring
- When context feels stale
- Task switching
- User requests `/context` command
## Context Principles
### Active Curation
- Keep only relevant information
- Remove completed task details
- Archive outdated patterns
- Focus on current work
### Signal-to-Noise Ratio
| High Signal | Low Signal |
|-------------|------------|
| Current APIs | Old experiments |
| Active patterns | Completed tasks |
| Recent decisions | Historical context |
| Project structure | Implementation details |
### Token Budget
| File | Limit | Purpose |
|------|-------|---------|
| CLAUDE.md | < 2000 tokens | Quick reference |
| Agent docs | < 500 per agent | Role definition |
| Skills | < 300 per skill | Methodology |
## Context Analysis Process
### Step 1: Measure Current State

### Token Counts
- CLAUDE.md: XXX tokens
- Agent docs: XXX tokens total
- Skills: XXX tokens total
- Total: XXXX tokens
### Staleness Check

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
