NorthwoodsSubstrate — Memory Store

Calls the deployed Northwoods Pack Worker (one Worker, five modules) to read/write persistent memory entries.

Workflow

1. Read pack.url and auth.token from ~/.claude/PAI/USER/SKILLCUSTOMIZATIONS/NorthwoodsPack/CONFIG.md.
2. Use one of three endpoints depending on intent:
   • Save: POST {pack.url}/substrate/remember
   • Search: POST {pack.url}/substrate/recall
   • List by tag/type: GET {pack.url}/substrate/list?tag=X&type=Y&limit=N
3. All requests require header X-Pack-Token: {auth.token}.

Save an entry

curl -s -X POST "$PACK_URL/substrate/remember" \
  -H "Content-Type: application/json" \
  -H "X-Pack-Token: $TOKEN" \
  -d '{
    "type": "breadcrumb",
    "body": "the thing to remember",
    "tags": ["topic1", "topic2"]
  }'

Common types: breadcrumb, decision, note, question, session. Returns {id, created_at}.

Search entries

curl -s -X POST "$PACK_URL/substrate/recall" \
  -H "Content-Type: application/json" \
  -H "X-Pack-Token: $TOKEN" \
  -d '{
    "query": "search term",
    "tags": ["optional"],
    "type": "optional",
    "limit": 20
  }'

Returns {entries: [...], count: N}.

List by tag

curl -s "$PACK_URL/substrate/list?tag=topic1&limit=10" \
  -H "X-Pack-Token: $TOKEN"

Failure behavior

If the Worker is unreachable, surface the error clearly. Do NOT silently swallow substrate writes — the user needs to know their thought wasn't saved.
