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:
- "Run this command and show me the output" — fast feedback loop, no copy-paste between terminal and chat.
- "Explain or write code based on the output we just looked at" — exec output is automatically injected into the model's context.
- "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.
Status
| Component | State |
|---|---|
| Repository skeleton | ✅ in this commit |
| Phase 0 manifest | ✅ docs/PHASE0.md — locked |
| Phase 0 implementation | 🔜 next session |
| Phase 1+ | 📋 enumerated in PHASE0.md §11 |
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-3runtimelibreadline8runtimelibc6runtime (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:
fast→dirac.fritz.box:8081(Qwen2.5-Coder-7B q4 8k ctx)deep→dirac.fritz.box:8080(Qwen2.5-Coder-7B q4 32k ctx)cloud→hossenfelder.fritz.box:8082(forwards to OpenRouter)
Replace these with your own llama.cpp endpoints if you're not on that LAN.
