Memory Checkpoint

Memory Checkpoint

Defines how to save a checkpoint and how to load one into SI. When to checkpoint is determined by the calling context — the project, the war room, or the agent's own judgment.

How to Save

Create a timestamped folder under memory/checkpoints/. Inside it, write one file per agent indexed by agent number.

memory/checkpoints/YYYYMMDD_HHMMSS/
├── agent-0.md
├── agent-1.md
└── ...

Each agent-N.md captures that agent's state. No length constraints — summarise what is needed to resume. A good checkpoint captures what would be hard to reconstruct, not a verbatim log.

# Agent <N> — <timestamp>

**Role**: <role>
**Trigger**: <what caused this checkpoint>
**Completed**: <what was just finished>
**Next**: <exact next action>

## State
<key facts, file paths, env state, decisions made, blockers — whatever is needed to resume>

After writing all agent files, update memory/SUMMARY.md — rewrite it to point to the latest checkpoint.

# Summary

- **Last checkpoint**: `memory/checkpoints/<timestamp>/`
- **Status**: <not_started | in_progress | blocked | complete>

## State
<key facts — file paths, important values, decisions that affect what comes next>

## Resume From
<one clear instruction: what to do next, any preconditions>

How to Load

On resume, inject into SI in this order:

1. Read memory/SUMMARY.md — always first. Get current status and the latest checkpoint path.
2. Read the relevant agent-N.md from the latest checkpoint folder — inject the file for your agent index.
3. Load other agents' files only if needed — e.g. to understand what another agent did.
4. Load older checkpoints only if needed — e.g. to understand a past decision.
