Core types and Capturer trait for oby — the wire-format and plugin contract shared by oby-hook, oby-tee, and the oby wrapper.
Wrapper-daemon for oby. `oby claude` launches Claude Code inside a wrapped pty, listens on per-agent unix sockets for hook traffic from oby-hook + oby-tee, and paints a togglable activity feed showing every tool call (with recovered stdout/stderr that the agent's shell pipelines discarded). Installs the `oby` binary.
PreToolUse / PostToolUse / SubagentStop hook dispatcher for oby. Routes Claude Code tool-call payloads to per-tool Capturers, rewrites Bash commands to recover discarded stdout/stderr via oby-tee, composes with peer hooks, and reports back to the oby wrapper over a unix socket.
In-pipeline helper for oby. Reads stdin, streams bytes to the wrapper's per-agent unix socket with a JSON header, fail-open. Injected by oby-hook's PreToolUse rewrite to capture stdout/stderr that would otherwise be discarded.
