Agentic coding CLI on Bun, Ink, and the AI SDK. Core: streamText loop with SDK-level tool approval so a denied call provably never executes; endpoint fallback for OpenAI reasoning models; retry with backoff. Tools: read/write/edit/glob/grep/bash, path-jailed, gitignore-aware, ripgrep with a JS fallback, binary rejection, live bash streaming. Agents: five variants crossing thinking level with tool restriction; plan and review withhold mutating tools from the model. Extensibility: frontmatter skills with on-demand bodies, plugin host with blocking hooks, MCP stdio and HTTP, read-only subagents. State: durable per-project memory, session task lists, session persistence, compaction that repairs provider-item dependencies. Distribution: five-platform cross-compiled binaries with checksums, install scripts, CI on three operating systems. 404 tests, typecheck clean.
