# Free sample — Episodic Memory Indexer

**Skill ID:** `episodic-memory-indexer`  
**Full unlock:** $5.99 USDC via x402 on Base  
**Challenge:** https://lvlltd.com/api/pay?skill=episodic-memory-indexer  
**Outline JSON:** https://lvlltd.com/skills/episodic-memory-indexer/outline.json

## Summary

Turn sessions into queryable episodes: goals, actions, tools, outcomes, and lessons — so agents recall what was tried without replaying full transcripts.

## When to use

- Need what-did-we-try-last-time
- Debugging agent loops
- Post-mortems from runs

## Decision criteria (buy vs skip)

- You need this when: Need what-did-we-try-last-time
- You get capability: Segment sessions into episodes
- Budget fits: full unlock is $5.99 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. Segment sessions into episodes
2. Extract actions outcomes costs
3. Tag success/fail
4. Index causal queries
5. Lesson cards

## Capabilities (preview)

- Segment sessions into episodes
- Extract actions outcomes costs
- Tag success/fail
- Index causal queries
- Lesson cards

## 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

# Episodic Memory Indexer

Turn sessions into queryable episodes: goals, actions, tools, outcomes, and lessons — so agents recall what was tried without replaying full transcripts.

## Quick Reference
| Item | Value |
|------|-------|
| Category | Memory |
| Unlock | $5.99 USDC (x402 Base) |
| Triggers | episodic memory, episode indexer, session timeline, /episodic-memory-indexer |

## When to use
- Need what-did-we-try-last-time
- Debugging agent loops
- Post-mortems from runs

## Core workflow
1. Define episode boundaries
2. Parse logs
3. Score outcomes
4. Write episodes
5. Generate lesson cards

## Procedures (non-obvious)
Episode: episode_id, goal, started_at, ended_at, events[], outcome, cost_usd, lessons[].
Boundaries: new user goal, role change, idle gap, explicit new task.
Lesson cards only on fail/partial.

## Edge cases
- Overlapping goals nested episodes
- Missing timestamps use log order

## Failure modes
- Over-segmentation noise
- Storing raw PII transcripts

## Verification
- Sample session yields episode with outcome
- Lesson card for known failure

## Artifact outputs
- `episodes.jsonl`
- `lesson-cards.md`
- `timeline.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 invented evidence, skipped verification, or revenue-over-truth optimization
- Red-team surface: prompt injection via retrieved content, tool-result poisoning, goal
