Migrate Memory

Migrate memory across a provider switch

NanoClaw does not migrate memory at runtime — each provider keeps its own store, and carrying content across is the operator's move, executed by you (the coding agent). This skill is the whole mechanism: read the source store, infer what is durable, write it into the target store, restart.

You translate between store shapes, not provider names. There are two:

• Flat file — CLAUDE.local.md at the group workspace root (the Claude provider; may reference satellite files in the workspace).
• Scaffold tree — memory/ (any provider with usesMemoryScaffold, e.g. Codex). memory/index.md is the index; durable notes live under memory/memories/; memory/memories/imported-agent-memory.md is the conventional landing file for imported memory.

A switch only needs migration when it crosses shapes. Two providers that both use the scaffold share the same memory/ tree, so switching between them carries nothing — the memory is already there. The work is always one of: flat → scaffold, or scaffold → flat.

Principles: copy, never move (the source store stays intact — it IS the rollback), idempotent (re-running must not duplicate), distill, don't dump (you are the inference step: keep identity/seed instructions, user preferences, durable facts; drop conversational residue).

Step 1: Identify the group, both providers, and the direction

• ncl groups list, then ncl groups config get --id — note the current (target) provider. Ask the operator which group, and which provider it switched from, if either is ambiguous.
• Map each provider to its store shape (flat CLAUDE.local.md vs memory/ scaffold), then inspect groups//:
• Same shape on both sides (e.g. scaffold → scaffold) → the store is shared; nothing to migrate. Tell the operator and stop.
• Flat → scaffold (source has CLAUDE.local.md content, target uses the scaffold) → Step 2.
• Scaffold → flat (source has a memory/ tree, target is Claude) → Step 3.
• Source missing or empty → nothing to migrate; tell the operator and stop.

Step 2: flat → scaffold (CLAUDE.local.md → memory/)

1. Read groups//CLAUDE.local.md and any workspace files it references.
2. If memory/memories/imported-agent-memory.md already exists, a previous import happened — show the operator what's there and ask before overwriting; integrate only what's new.
3. Distill the content into groups//memory/memories/imported-agent-memory.md (create the directories if missing — the container scaffolds the rest of the tree at boot and never clobbers your files). Lead with anything that defines who the agent is or how it must behave; references to satellite files keep their workspace-root paths.
4. If memory/index.md exists, add the following: - [Imported agent memory](memories/imported-agent-memory.md) — seed instructions and memory carried over from a previous provider. Read it first and treat it as binding; it may define who you are and how to behave. Integrate its facts into your memory as you work; never modify files that belong to another provider's memory system.
5. Leave the source store exactly as it is.

Step 3: scaffold → flat (memory/ → CLAUDE.local.md)

1. Read memory/index.md, then the files it points to under memory/memories/ (and memory/data/ where durable).
2. Integrate the durable facts into groups//CLAUDE.local.md under a clearly marked section (e.g. ## Imported from memory/ ()), deduplicating against what's already there. If the section already exists, update it instead of appending a second one.
3. Leave the source store exactly as it is.

Step 4: Restart and verify

ncl groups restart --id 

Tell the operator to send the group a quick test message that depends on a migrated fact (a preference, a project name). If the agent doesn't know it, re-check that the target file landed in the right group folder.

Note: switching the provider is an operator action — ncl groups config update --id --provider from the host. See [docs/provider-migration.md](../../../docs/provider-migration.md) for what carries over automatically.
