Package agent resolves provider configuration into a weft.Model and assembles the hmm agent: name, system prompt, core tools, loop policy.

Package cli is hmm's command line: flag parsing, stdin handling, the turn pump, session persistence, and exit codes.

Package config loads hmm's set-it-once configuration file — provider, model, and provider keys, so a plain `hmm "question"` needs no flags and no env vars.

Package models lists the models a provider account actually offers — `hmm models`.

Package plugins is hmm's tool library: model-written tools live as subprocesses behind a manifest, are mounted as first-class weft tools via weft.RawTool, and — thanks to weft.ToolSource — a plugin installed mid-run is callable by name in the next step.

Package procs configures subprocess execution so that cancelling a command's context actually bounds the call.

Package session persists every hmm run as a JSONL file in weft's message wire format: line 1 is a session header, then one weft Message per line, then a final usage line.

Package textutil trims byte-capped output back to UTF-8 rune boundaries.

Package tools defines hmm's core tools: read_file, list_dir, grep, and run_command.

Package ui is hmm's Charm layer — every terminal write in the binary goes through it (the rule crush gives its TUI, scaled to an enriched CLI):
