A TUI that displays Claude Code's streams token-by-token — thinking, text, and tool calls — by sitting as a pass-through proxy between Claude Code and the Anthropic API.

No extra usage: it never issues requests of its own; it observes the SSE stream of requests Claude Code was already making, forwarding bytes verbatim and unbuffered.

                               TUI: live token feed

Usage

cargo build --release
./target/release/claude-cloak

Then point Claude Code at the proxy, either per-shell:

export ANTHROPIC_BASE_URL=http://127.0.0.1:8484
claude

or globally in ~/.claude/settings.json:

{ "env": { "ANTHROPIC_BASE_URL": "http://127.0.0.1:8484" } }

Note: with the global setting, Claude Code can't reach the API while the proxy isn't running.

Keys

key	action
`q` / `Esc`	quit
`Tab` / `Shift-Tab`	switch session
`j`/`k`, arrows, PgUp/PgDn	scroll (disables follow)
`f` / `G` / `End`	follow live tail
`g` / `Home`	jump to top

Display

✻ thinking — dim italic, streamed token-by-token
text — rendered as markdown (tui-markdown)
⚙ tool calls — input JSON pretty-printed on completion, raw fragments while streaming
meta — message boundaries with model, context size, stop reason, token counts
errors — API/stream errors in red

Sessions are keyed by the Claude Code session ID found in request metadata; concurrent requests (subagents) tap independently.

--headless runs the proxy without the TUI. CT_PORT overrides the port (default 8484).
