worker holds the write tools and routes every write and command through the parent's approval gate: same permission rules, same guard, same prompt, flagged as coming from a subagent. Without an approval channel, as in headless runs, the kind is not offered at all rather than silently downgraded to read-only.

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.
