marfrit 8adebd52cc repl: _record_usage helper + opts.category at 5 sites (Phase 7 commit #3)
Wires broker.lua's on_delta("usage", payload) and broker.chat's
(text, usage) return to the ctx accumulator via a single chokepoint.

Changes:

  - Forward decl `local _record_usage` near _bg_spawn — same pattern;
    the summarize-on-evict closure in make_summarize_fn (built at
    line 299) needs lexical access to _record_usage (assigned at
    line 695), so forward-declare and assign-without-`local`.

  - _record_usage(model, category, usage) — R5 central chokepoint:
    routes to ctx:add_usage, then checks the per-threshold warn
    state. R4: cost_warn_state has two independent flags (dollars
    and tokens) so first-to-fire doesn't suppress the other. R10:
    warn message uses $%.6f for sub-cent precision.

  - call_broker wrapper: wrapped on_delta now branches on
    kind == "usage" -> _record_usage(payload.model, payload.category,
    payload). R2: keys by payload.model (set inside broker.lua from
    model_cfg.model). When fallback fires, broker is called with
    fb_cfg, so payload.model IS the fallback's name automatically —
    wrapper doesn't track primary-vs-fallback itself.

  - 5 caller sites wired with opts.category:
      ask_ai call_broker             -> category="main"
      summarize-on-evict             -> category="summarize"
      DELEGATE: handler              -> category="delegate"
      :memory summarize              -> category="memory_summarize"
      :delegate meta                 -> category="delegate"

  - All 4 broker.chat call sites switched from
      local reply, err = broker.chat(...)
    to
      local reply, second = broker.chat(...)
    branching on reply nil-ness to interpret second (err on failure,
    usage on success). Captured usage routes through _record_usage.

E2E verified against live cloud broker:
  - cloud prompt -> reply "Hi! 👋"
  - Warn fired: "session cost $0.000219 has crossed warn_at_dollars=$0.000010"
  - R10 sub-cent precision visible in both numbers.

Norris + safety paths still untouched — commit #4 wires those.

Regression: test_safety 87/87, test_router_model 31/31, repl loads.

aish

aish — AI-augmented conversational shell.

A single REPL that interleaves shell command execution and language-model conversation, backed by a llama.cpp HTTP broker. Implementation is LuaJIT 2.x with FFI bindings to libcurl, GNU readline, and libc — no C extensions, no build step, one source tree.

Why

Three flows that currently live in three windows fold into one:

  1. "Run this command and show me the output" — fast feedback loop, no copy-paste between terminal and chat.
  2. "Explain or write code based on the output we just looked at" — exec output is automatically injected into the model's context.
  3. "Plan and execute a multi-step task with confirmation gates" — landing in Phase 3 as Chuck Norris autonomous mode.

aish is not a wrapper around bash. It's a first-class interactive environment where the shell is one of several execution channels.

Every module file currently raises not implemented (Phase 0 pending) when called. luajit main.lua fails loudly at the first un-implemented function, never silently.

Build / runtime dependencies

System packages (Debian / ALARM / Arch names):

  • luajit (>= 2.0)
  • libcurl4 / libcurl-openssl-3 runtime
  • libreadline8 runtime
  • libc6 runtime (always present)

No compilation, no luarocks, no make. Just luajit main.lua.

Running

Once Phase 0 ships:

luajit main.lua                          # uses ~/.config/aish/config.lua
luajit main.lua --config ./config.lua    # explicit config path
AISH_CONFIG=/path/to/config.lua luajit main.lua

Config resolution order is documented in docs/PHASE0.md §10.

Configuration

config.lua is a Lua file returning a single table. The committed config.lua in this repo is both the canonical example and the development-fallback config (lowest precedence). Copy it to ~/.config/aish/config.lua and edit endpoints to your local llama.cpp servers, or point AISH_CONFIG at your own.

The default endpoints assume mfritsche's home network:

  • fastdirac.fritz.box:8081 (Qwen2.5-Coder-7B q4 8k ctx)
  • deepdirac.fritz.box:8080 (Qwen2.5-Coder-7B q4 32k ctx)
  • cloudhossenfelder.fritz.box:8082 (forwards to OpenRouter)

Replace these with your own llama.cpp endpoints if you're not on that LAN.
