marfrit cf4d79dd9d docs/PHASE3: analyze + baseline — \C-n mechanics, LLM latency, module pre-state
Analyze findings folded into the manifest:

  A1. \C-n binding can't toggle mid-prompt without rl_insert_text /
      rl_redisplay. Solution: bind those (one cdef + 2 wrappers in
      ffi/readline.lua) so \C-n inserts ":norris " at the cursor; user
      types goal + Enter. Routes through existing meta dispatch.

  A2. broker has no max_tokens passthrough. Add opts.max_tokens for
      the LLM second-opinion path (terminates at ~2 tokens; verified
      proxy honors it).

  A3. Phase 2 tool-sub-loop pattern IS the planner shape. safety.norris_step
      is the per-iteration extraction; driver loop in repl.lua.

Module-changes table (§3) updated with the rl_insert_text and
max_tokens rows.

Baseline doc (PHASE3-baseline.md, 80 lines) captures:
  - LLM second-opinion latency: 425-1162ms per probe, all 5 test
    cases correct. Worst-case 16-step Norris = ~20s overhead; with
    static-pattern fast-path + session cache, ~5s realistic.
  - Module pre-state at commit f26cbd9 (Phase 2 tip): LOC + state
    per file before Phase 3 edits.
  - Six static-pattern Lua-match sanity checks (all correct).
  - Carries: aish#15 (still open), aish#14, aish#32/#33.

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.
