nevermore

An interactive coding agent in pure C — quoth's spoken-word sibling.

"Quoth the raven: nevermore."

nevermore chats with AI models (Charm Hyper, Ollama local daemon and Ollama Cloud, OpenAI, OpenRouter) from a terminal, with an agent loop that can read, edit, and search files and run commands. It is a first-class citizen of the portty terminal: kitty keyboard protocol, OSC 52 clipboard, Lottie spinner via OSC 5555, sixel image attach — graceful degradation everywhere else.

Pre-alpha. No backwards-compatibility constraint.

Autotools, house style:

./autogen.sh
mkdir -p build && cd build
PKG_CONFIG_PATH="$HOME/.local/lib/pkgconfig:$HOME/.local/lib64/pkgconfig" \
 ../configure --prefix="$HOME/.local"
make -j$(nproc)
make check
make install

Or from the chestso monorepo root: make nevermore.

Dependencies:

• boba (required) — TUI runtime, textinput, styles
• TLS (optional, per-OS, never libcurl) — Schannel on Windows, Secure Transport on macOS, mbedTLS or OpenSSL on Linux; --with-tls=none builds a plain-HTTP-only client (fine against a local Ollama daemon)

nevermore # interactive chat (boba TUI)
nevermore ask "explain this repo" # one-shot
nevermore models # provider model catalog
NEVERMORE_PROVIDER=openrouter nevermore ask "..."

Provider keys come from the environment: HYPER_API_KEY, OLLAMA_API_KEY, OPENAI_API_KEY, OPENROUTER_API_KEY.

src/ the nevermore binary: entry point, providers, wire
 client, transport, SSE, JSON, agent loop, tools,
 session, TUI (headers live alongside sources —
 CLI app, no library)
tests/ standalone test binaries (RUN_TEST/TEST_SUMMARY pattern)
docs/ wire specs ported from quoth + platform notes
data/ static model catalogs
