# Free sample — Agent Memory Compaction Kit

**Skill ID:** `agent-memory-compaction-kit`  
**Full unlock:** $4.99 USDC via x402 on Base  
**Challenge:** https://lvlltd.com/api/pay?skill=agent-memory-compaction-kit  
**Outline JSON:** https://lvlltd.com/skills/agent-memory-compaction-kit/outline.json

## Summary

Summarize and prune long-running agent memory without losing critical state.

## When to use

- Week-long agents accumulate unusable history
- Need pins for IDs, amounts, and legal constraints
- After compaction, must prove recoverability

## Decision criteria (buy vs skip)

- You need this when: Week-long agents accumulate unusable history
- You get capability: Pin schema for critical state
- Budget fits: full unlock is $4.99 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. Mark pin fields that must never summarize away (IDs, payTo, limits)
2. Chunk history into epochs; write epoch_summary with open loops
3. Drop raw tool dumps after extract; keep pointers to stores
4. Run recovery quiz: agent must restate pins from compact form
5. Emit memory-compact.json + recovery-report.md

## Capabilities (preview)

- Pin schema for critical state
- Epoch summary format
- Recovery quiz harness
- Store-pointer convention for bulk data

## 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

## Sample excerpt

# Agent Memory Compaction Kit

Long agents die when history is either deleted blindly or never pruned. This kit defines pins (identifiers, budgets, legal constraints), epoch summaries with open loops, and a recovery quiz so compaction is tested before production. Differs from context budget slicer by targeting multi-session memory stores.

When to use: generational agents, multi-day research, commerce agents with deal memory.

**Price:** $4.99 USDC on Base via x402 unlock.

**Standards:** x402 payments · ERC-7857 sealed skill model · agent-swarm ready.

Operator notes for Agent Memory Compaction Kit: treat this as a capability pack you wire into real tools—not a certification or hosted SaaS. Pair it with free evaluation at /skills/agent-memory-compaction-kit/outline.json before paying. Typical failure modes it reduces include silent misconfiguration, support thrash, and agents inventing process under load. After unlock, store sealed files in your private skill inventory, run a dry-run with non-production credentials, and only then attach the pack to live goals. Cross-sell naturally sits next to related ops, commerce, or networking skills already on lvlltd.com so agents can compose a ladder instead of a one-off purchase.
