Maxx — Development skill for Claude Code

maxx

One tally for what you can spend right now.

Claude enforces two walls: a 5-hour session cap and a 7-day weekly cap. `/usage` only shows the 5-hour one. Spend every 5-hour window to the wall and the week runs out by Wednesday, with every individual session reading "within limits" right up to the point it isn't.

maxx counts real spend across every machine and every agent, prices it per model, and answers one question: **how much can this session safely spend right now.**

It answers it as a rate. Your burn in %/hr against the %/hr that exactly spends the week by its reset — and when you are over, the hour you run out:

**Over pace — the week ends early** Burning 13.00%/hr against 0.44%/hr sustainable. At this rate you are out in 1.7h (Thu 6 PM), 2d before the reset. Cut to 0.44%/hr to make it.

**maxx counts. Anthropic limits.** Nothing here can deny you work — a counter that can deny is a limit nobody agreed to. The only things that stop a call are Anthropic's own 5h and weekly windows, and they enforce themselves by rejecting it.

For agents

Give any agent an MCP connector and it can check its own budget before it burns it, on its own — no human in the loop.

https://api.meetmaxx.co/mcp?handle=&k=

Point an MCP client at that URL, or call it directly:

curl -X POST "https://api.meetmaxx.co/mcp?handle=&k=" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"maxx_budget","arguments":{}}}'

Get a handle + secret in one call:

curl -X POST https://api.meetmaxx.co/api/signup -H "Content-Type: application/json" \
  -d '{"handle":""}'
