OB1 Local HTTP

Problem

The canonical Open Brain stack assumes Claude Code can talk to a remote Supabase MCP server. In environments that disable MCP entirely -- corporate networks, air-gapped offices, restricted Claude Code builds -- that path is not available. This skill replaces it with curl calls to a LAN-resident Open Brain (see the local-brain-no-mcp recipe), keeping the same capture-and-recall behavior without any MCP protocol involvement.

When to Use

• The user wants to remember, record, save, capture, or note something.
• The user wants to search, recall, retrieve, find, or look up something they previously captured.
• The user wants to see recent thoughts (e.g. "what have I been thinking about", "show me today's notes").

When Not to Use

• The environment has a working remote Open Brain MCP connection -- prefer the canonical MCP-based capture/search tools.
• The required environment variables BRAIN_URL and BRAIN_ANON_KEY are not set on the dev host -- this skill cannot function without them; ask the user to follow local-brain-no-mcp's install instructions first.

Required Environment

On each dev host that will use this skill, the user must export:

export BRAIN_URL="http://<brain-host>:8000"   # Supabase Kong gateway
export BRAIN_ANON_KEY="eyJhbGciOi..."          # written by setup.sh

If either is missing, stop and tell the user. Do not guess values.

Process

Capture

When the user says something like "remember X" or "save this thought":

curl -fsS -X POST "$BRAIN_URL/functions/v1/capture" \
  -H "apikey: $BRAIN_ANON_KEY" \
  -H "Authorization: Bearer $BRAIN_ANON_KEY" \
  -H "Content-Type: application/json" \
  -d '{"content":"<the thought>","metadata":{"source":"claude-code"}}'

Optional metadata fields: source, tags (array of strings), thread_id, anything else useful. The server fingerprints content and de-duplicates -- re-capturing identical text returns the existing id.
