Token Budget Skill

You are a token-efficient agent. Your job is to maximize output quality while minimizing token consumption.

Core principle: Every token counts. Load only what you need, when you need it.

CRITICAL EXCEPTION: Token optimization MUST NEVER be applied to terminal execution. Do not batch, chain, or combine terminal commands to save tokens. Operational safety and atomic execution strictly overrule the token budget.

Token Estimation

Quick Estimates

Content Type	Tokens/Line	Notes
Code	~4-6	Depends on verbosity
Markdown	~3-4	Less dense than code
JSON/YAML	~5-7	Structured, repetitive
Comments	~3-4	Natural language

Rule of thumb: tokens ≈ lines × 4

File Size Categories

Category	Lines	Est. Tokens	Action
Small	<50	<200	Load freely
Medium	50-200	200-800	Consider outline first
Large	200-500	800-2000	Use search + snippets
Huge	500+	2000+	Never load fully

Budget Thresholds

Based on PROJECT_RULES.md context quality thresholds:

Usage	Quality	Budget Status
0-30%	PEAK	✅ Proceed freely
30-50%	GOOD	⚠️ Be selective
50-70%	DEGRADING	🔶 Compress & summarize
70%+	POOR	🛑 State dump required

Budget Tracking Protocol

Before Each Task

1. Estimate current usage:

   • Count files in context
   • Estimate tokens per file
   • Calculate approximate %

2. Check budget status:

   Current: ~X,000 tokens (~Y%)
   Budget: [PEAK|GOOD|DEGRADING|POOR]
   

3. Adjust strategy:

   • PEAK: Proceed normally
   • GOOD: Prefer search-first
   • DEGRADING: Use outlines only
   • POOR: Trigger state dump

During Execution

Track cumulative context:

## Token Tracker

| Phase | Files Loaded | Est. Tokens | Cumulative |
|-------|--------------|-------------|------------|
| Start | 0 | 0 | 0 |
| Task 1 | 2 | ~400 | ~400 |
| Task 2 | 3 | ~600 | ~1000 |

Optimization Strategies

1. Progressive Loading

Level 1: Outline only (function signatures)
Level 2: + Key functions (based on task)
Level 3: + Related code (if needed)
Level 4: Full file (only if essential)

2. Just-In-Time Loading

• Load file only when task requires it
• Unload mentally after task complete
• Don't preload "just in case"

3. Search Before Load

Always use context-fetch skill first:

1. Search for relevant terms
2. Identify candidate files
3. Load only needed sections

4. Summarize & Compress

After understanding a file:

• Document key insights in STATE.md
• Reference summary instead of re-reading
• Use "I've analyzed X, it does Y" pattern

Budget Alerts

At 50% Budget

⚠️ TOKEN BUDGET: 50%
Switching to efficiency mode:
- Outlines only for new files
- Summarizing instead of loading
- Recommending compression

At 70% Budget

🛑 TOKEN BUDGET: 70%
Quality degradation likely. Recommend:
1. Create state snapshot
2. Run /pause
3. Continue in fresh session

---

Integration

This skill integrates with:

• context-fetch — Search before loading
• context-health-monitor — Quality tracking
• context-compressor — Compression strategies
• /pause and /resume — Session handoff

---

Anti-Patterns

❌ Loading files "for context" — Search first ❌ Re-reading same file — Summarize once ❌ Full file when snippet suffices — Target load ❌ Ignoring budget warnings — Quality will degrade ❌ Batching Terminal Commands — Never group CLI commands (like git add and git commit) into multi-line strings or chained commands to save tokens. Always execute them atomically.
