Module format 

Shared renderers for the value surface. Subtle by construction: one dim line, no exclamation, nothing when there is nothing measured to say.

Structs

Style

How a channel can render: colour (ANSI dim) and Unicode glyphs are independent — a Claude status line has colour but no TTY, a legacy Windows console has a TTY but no reliable glyphs.

Functions

brand_line

The Claude Code status line in the Context Gateway’s terms: ◆ LeanCTX │ SELECT 12 files · 30 commands │ CONTROL ⛨ 3 enforced │ TOKENS −1.2M kept out · 60% leaner · 41 cached. SELECT is what reached Claude through the gateway, CONTROL what the rules enforced before the handoff, TOKENS what stayed out of context. A group with nothing measured is left out, and so is the line when all are.

compact

◆ −1.2M tok ⛨ 3 for a shell prompt: the shortest honest form, never coloured (prompt escaping differs per shell, so the caller wraps it).

one_line

◆ lean-ctx −1.2M tok · 41 cached · ⛨ 3 — or None when nothing measured happened yet (a zero would read like lean-ctx is not working).

security_phrases

Human wording for a security tally, in the contract’s words: secrets are kept out of context, commands and paths blocked, injections flagged.
