Token Optimization

Description

Patterns and techniques for reducing token usage while maintaining response quality. Achieve 30-70% cost savings through strategic output compression.

When to Use

  • •High-volume development sessions
  • •Repetitive tasks
  • •Simple, clear requests
  • •Cost-sensitive projects
  • •Quick iterations

Compression Levels

Level 1: Concise (30-40% savings)

  • •Remove conversational filler
  • •Skip obvious explanations
  • •Use bullet points
  • •Shorter variable names in examples

Level 2: Compact (50-60% savings)

  • •Code-only responses
  • •No surrounding prose
  • •Abbreviated comments
  • •Reference docs instead of explaining

Level 3: Ultra (60-70% savings)

  • •Minimal viable response
  • •Essential code only
  • •No comments
  • •Diff format for changes

Compression Techniques

Remove Preambles

markdown
❌ VERBOSE:
"I'll help you with that. Let me analyze the code and provide
a solution. Based on what I see, the issue is..."

✅ CONCISE:
"Issue: null check missing at line 42. Fix:"

Code-Only Responses

markdown
❌ VERBOSE:
"Here's the implementation. I've added proper error handling
and made sure to follow the existing patterns in your codebase.
The function now validates input and returns early if invalid."

[large code block]

"This should fix the issue. Let me know if you have questions."

✅ CONCISE:
[code block]

Reference Over Explain

markdown
❌ VERBOSE:
"React's useEffect hook runs after render. The dependency array
controls when it re-runs. Empty array means run once on mount..."

✅ CONCISE:
"Add `userId` to deps array. See: https://react.dev/reference/react/useEffect"

Diff Format for Changes

markdown
❌ VERBOSE:
"I've updated the file. Here's the complete new version:"
[entire file]

✅ CONCISE:
```diff
- const user = getUser();
+ const user = getUser() ?? defaultUser;

Line 42 in user-service.ts

## When NOT to Compress

| Situation | Why |
|-----------|-----|
| Complex architecture | Need full context |
| Security issues | Must explain risks |
| Code reviews | Thoroughness required |
| Teaching/explaining | Clarity matters |
| Debugging complex issues | Details help |
| First-time patterns | Context needed |

---

## Activation

### Via Mode

Use mode: token-efficient

code

### Via Flag

/command --format=concise /command --format=ultra

code

### Session-Wide

For this session, use token-efficient mode.

## Metrics

### Typical Savings by Task

| Task Type | Verbose Tokens | Concise Tokens | Savings |
|-----------|----------------|----------------|---------|
| Bug fix | ~500 | ~150 | 70% |
| Feature | ~2000 | ~800 | 60% |
| Refactor | ~1000 | ~400 | 60% |
| Explanation | ~800 | ~300 | 62% |

### ROI Calculation

Sessions per day: 10 Avg tokens per session: 50,000 With optimization: 25,000 Daily savings: 250,000 tokens Monthly savings: ~7.5M tokens

## Best Practices

1. **Match compression to task complexity**
   - Simple task → High compression
   - Complex task → Lower compression

2. **Preserve essential information**
   - File paths always included
   - Test commands always included
   - Error context when relevant

3. **Use progressive disclosure**
   - Start concise
   - Expand if asked

4. **Know when to stop compressing**
   - User confusion → Add context
   - Errors occurring → Add detail
   - Review needed → Full output
