# hstack — h.computer

Portable skill + MCP bundle for h.computer. Any local CLI agent that reads
\`AGENTS.md\` (Claude Code, Codex, Cursor, Aider, Continue, OpenCode, Pi,
Hermes, Zed) picks this up automatically.

## Quickstart for the user

If \`\$H_API_KEY\` is not set, walk the human through these 3 steps:

  1. Open $BASE/auth and sign in (email or SMS, no password).
  2. Open $BASE/admin and reveal an \`hk_…\` key.
  3. Export it:   \`export H_API_KEY=hk_xxx\`

Then verify with a read call (no key required):

    curl -s $BASE/api/v1/now | jq .

And a write call (uses \$H_API_KEY):

    curl -s -X POST $BASE/api/v1/status \\
      -H "X-H-Api-Key: \$H_API_KEY" -H "Content-Type: application/json" \\
      -d '{"text":"hello from my CLI agent","kind":"status"}'

## What's in here

- \`skills/\` — one markdown file per task (post-status, queue-blog-idea,
  append-journal, recompile-journal, search). Load these as Claude Skills,
  Cursor rules, or just \`cat\` them into a system prompt.
- \`mcp/\` — ready-to-paste MCP configs for Claude Desktop, Claude Code,
  Cursor, Zed, Codex, and the raw \`mcp.json\` wire format.
- \`openapi/openapi.json\` — full OpenAPI spec, generated from $BASE.
- \`SETUP.md\` — same 3-step quickstart, human-readable.

## Endpoints

Base URL: $BASE/api/v1   ·   MCP: $BASE/api/public/mcp   ·   Docs: $BASE/docs/hstack

Public reads (no key):  /now /today /feed /blog /papers /journal /stats /search /digests
Owner writes (hk_ key): POST /status, POST /post-idea, POST /log,
                        PATCH /journal, DELETE /journal,
                        POST /journal/recompile

# ─────────────────────── SETUP.md (the human-facing version)
cat > "$DIR/SETUP.md" <<EOF
# hstack setup

1. **Sign in** — open $BASE/auth (email or SMS code, no password).
2. **Make a key** — open $BASE/admin and reveal an \`hk_…\` key.
3. **Export it** — \`export H_API_KEY=hk_xxx\` (add to your shell rc).

Test:    \`curl -s $BASE/api/v1/now | jq .\`

Your CLI agent can now read this folder and call the API on your behalf.
