marfrit 09800d192a config: Phase 2 mcp example block + deep model switch
Phase 2 commit #7 (final) per docs/PHASE2.md §12. Two changes bundled:

(1) commented-out mcp = {...} example block (~40 lines) at the end of
    config.lua showing the Phase 2 schema:
      - mcp.servers — alias → {url, auth_token | auth_env}
      - mcp.auto_approve — "<alias>.<tool>" or "<alias>.*" globs
      - mcp.max_tool_depth — sub-loop budget per ask_ai turn
    The block is OFF by default; uncomment + adjust per fleet to
    activate. Documentation-only; no behavior change to existing
    configs (mcp_sessions stays empty, tools_schema() returns [],
    broker omits the field — full Phase 1 compatibility).

(2) User-authored: deep model preset switched from
    mistral-nemo-12b-instruct to qwen3-30b-a3b-instruct, with a 10-min
    timeout_ms accommodating the larger model's RK3588 inference time.
    Reason: nemo backend is dormant per the proxy /v1/models discovery
    (aish#23 now returns 404 cleanly for unknown models instead of
    silent fallback); qwen3-30b is the practical "deep" alternative.

Phase 2 implementation is now complete — 7 of 7 commits landed:
  #1 6c194de  mcp.lua + ffi/curl status_code + PHASE0 §4 amendment
  #2 0fde77f  safety.lua confirm_tool_call
  #3 7c221a8  context.lua tool turns + use_tool_role fallback
  #4 c736d0e  renderer.lua tool-call frames
  #5 efdc728  broker.lua opts.tools + tool_call accumulator
  #6 7e9cfff  repl.lua sub-loop + :mcp meta + system-prompt block
  #7 (this)   config.lua example + deep model switch

Next phase-loop step: verify (Phase 7). Files written are wired and
isolated-tested; end-to-end model-driven verification waits on either
a more compliant model or explicit forcing of tool_calls from the
prompt — known to be marginal with the loaded qwen-1.5b but proven
correct against direct probes.

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.
