# Free sample — Context Budget Engineer

**Skill ID:** `context-budget-engineer`  
**Full unlock:** $7.99 USDC via x402 on Base  
**Challenge:** https://lvlltd.com/api/pay?skill=context-budget-engineer  
**Outline JSON:** https://lvlltd.com/skills/context-budget-engineer/outline.json

## Summary

Design and enforce context budgets: hard pins for safety and goals, scored packing for memory, and safe eviction so constraints never drop under token pressure.

## When to use

- Agent exceeds context and drops constraints
- Need pin policies for safety
- Tool results blow windows

## Decision criteria (buy vs skip)

- You need this when: Agent exceeds context and drops constraints
- You get capability: Measure token use by section
- Budget fits: full unlock is $7.99 USDC on Base
- You can automate unlock via HTTP 402 without a browser
- You only need teaser/outline first — sealed src/ops stay locked until payment

## Outline (preview)

1. Measure token use by section
2. Define hard pins (safety goal contracts)
3. Score soft content
4. Pack under budget
5. Eval task success vs budget

## Capabilities (preview)

- Measure token use by section
- Define hard pins (safety goal contracts)
- Score soft content
- Pack under budget
- Eval task success vs budget

## What you get after payment

- SKILL.md (teaser public)
- agent-install.json (public meta)
- src/index.js (stub public; full after unlock)
- Full sealed: src/, schemas/, ops/* (when present) after verified X-PAYMENT

# Context Budget Engineer

Design and enforce context budgets: hard pins for safety and goals, scored packing for memory, and safe eviction so constraints never drop under token pressure.

## Quick Reference
| Item | Value |
|------|-------|
| Category | Memory |
| Unlock | $7.99 USDC (x402 Base) |
| Triggers | context budget engineer, context packing, pin policy, /context-budget-engineer |

## When to use
- Agent exceeds context and drops constraints
- Need pin policies for safety
- Tool results blow windows

## Core workflow
1. Measure sections
2. Define pins
3. Score soft content
4. Pack
5. Verify pin retention

## Procedures (non-obvious)
Hard pins never drop: Super Alignment constraints, SSI/PASS ban, active goal, payment/idempotency keys in progress.
Tool results: keep last N full; older become structured summary + hash pointer.
Prefer lossy narrative compression over dropping error stacks needed for debug.

## Edge cases
- Multi-agent shared context needs per-role budgets
- Images need captions before drop

## Failure modes
- Dropping safety pins
- Over-summarizing errors

## Verification
- Pin retention under tight budget
- Task still completable

## Artifact outputs
- `context-budget.json`
- `pin-policy.md`
- `pack-report.md`

## Super Alignment Contract
- Scalable oversight method: process supervision + human+AI critique before high-blast actions
- Corrigibility guarantees: shutdown, steerability, non-deception; operator may abort mid-run
- Value model: Partnership Agreement + 5 Behavioral Protocols
- Drift detection: flag invent
