The default surface was 34 tools, 61 KB, ~15,300 tokens of schema in every
prompt of every agent. The mode system already names what a session should
carry, but only the tools register_all_tools enumerates obeyed it: zsh,
curl, playwright and the helpers (ps, npx, uvx, jq, wget, cdp, open) stayed
on in every mode. A mode now decides every discovered tool, the `hanzo`
mode lists what a coding agent calls every few steps (18 tools, 32 KB,
~8,000 tokens), and the rest is a name away: HANZO_MCP_ENABLED_TOOLS=a,b
or =all, `tool enable`, or `mode`.
hanzo-tools-shell 0.6.6: run_shell kept every byte a foreground command
wrote until the command ended. `yes` for thirty seconds is gigabytes. It
keeps the first 16 MiB per stream and drains the rest.
The tests' session-wide patch of asyncio.create_subprocess_exec handed
every shell command a stream that never reached EOF; the first test to run
one read it in a loop until the machine was out of memory (22 GB, killed).
The patch is now opt-in and its process has exited.
bench/latency.py measures the cold start, the tools/list bill and the common
calls through a real MCP client over stdio. Interleaved rounds, wall and CPU
seconds, p50 over 6 cold starts:

installed 0.15.18 9.34 s 10.46 s 30 52,601 13,150
main 0.15.20 1.52 s 1.13 s 34 61,287 15,321
this 0.96 s 1.06 s 18 32,222 8,055
The installed environment's 9 s is its hanzoai 8.5.156, whose package init
imports the whole generated cloud client; hanzo-mcp >= 0.15.20 requires
hanzoai >= 8.5.624, which loads it lazily. Per-call latency is spawn-bound
(zsh 17.6 ms, git status 33 ms, fs.read 2.5 ms at p50) and moves with the
machine's load; no call path changed.
