Bands

Measures a Claude Code session's fixed startup context payload per item at a pinned binary version, including per-tool attribution of the built-in tool pools that /context reports only as totals, derived by A/B deny differencing. Falls back from an SDK meter to a headless /context parser, then to an error rather than a wrong number. Keeps a before/after ledger per lever. Shows a live context...

Keep the main conversation's prompt cache warm by automatically forking its last request, tools denied and billed like any request, shortly before the cache expires; switch its lifetime between 5m and 1h, and show each refresh's cost and estimated saving.

Painel ao lado da conversa com visão geral, agentes (quem chamou quem, recados e rodadas), turnos, diffs como no VS Code, árvore de arquivos ao vivo, contexto e custo e inventário de plugins, e uma linha de resumo acima do prompt. Só observa, a não ser quando você manda parar um agente.

KOZMOS Aurora: northern lights above the prompt while the model thinks. Shifting curtains whose intensity and speed follow the effort level (low is gentle, max is wild), a calmer single wave while it responds, and a label like 'thinking · xhigh · 12s'. /aurora toggles it.

KOZMOS Blackbox: a flight recorder above the prompt. A live Gantt of the current turn: the main loop and each subagent on its own lane, every tool call a bar in its family color, model requests as ticks, a moving now cursor on an auto-scaling time axis; the last turn stays dimmed until the next. /blackbox toggles it.

KOZMOS Clawdling: a pixel crab companion that lives above the prompt. It blinks and sways, scuttles while tools run, thinks in bubbles, sweats past 80% context, dozes near the 5-hour limit and dances on a five-turn streak. It earns XP from tools and turns, levels up into a party hat, sunglasses, a scarf and a crown, and quips about what it sees. /clawdling toggles it, /clawdling feed treats it.

KOZMOS Glyphfall: matrix rain of tool activity above the prompt while Claude works. Every tool call drops its name and detail as a wave of letters, colored by tool family, with bright heads and fading tails, over a sparse rain of katakana; the last five tools sit below as colored chips. /glyphfall toggles it.

KOZMOS Halo: a one-row mood line above the prompt whose color and motion tell what Claude is doing: calm blue breathing when idle, a violet flow while it requests and writes, a magenta shimmer while it thinks, the running tool's color racing across, a red flash when a tool fails, an amber blink when it waits for you. /halo toggles it.

KOZMOS Heartline: a neon EKG of the session drawn above the prompt. Every tool call is a spike colored by its family, every model request a blip, a failed tool a red inverted spike; the trace drifts green to red with context fill, with a live bpm (tool calls per minute) and ctx readout. /heartline toggles it.

KOZMOS Lofi: generative lo-fi music while Claude works. Four original synthesized loops (focus, deep, night, sunny: warm chord pads, an electric piano, soft kick and hats with swing, vinyl crackle) loop from the start of a turn until it ends, and stop when Claude is idle. Opt-in: /lofi on. A tiny band shows '♪ lofi · deep' with a dancing equalizer while it plays.

KOZMOS Orrery: subagents as planets circling a central sun above the prompt. Running agents orbit at a speed set by their tokens per second, finished ones settle into a faint outer ring, failed ones flash a red cross; a legend names up to four with type and elapsed time. /orrery toggles it.

KOZMOS Questline: task progress above the prompt. One segmented bar for the session's todos and tasks (done green, running violet and pulsing, waiting gray), the count, what is running now and for how long. Hides itself two minutes after everything is done. /questline toggles it.

KOZMOS Skies: the session's weather above the prompt. Tool failures, context and rate-limit pressure, stalls and the local hour make clear skies, clouds, rain, storms with lightning, fog, a starry night, or a rainbow after a storm clears; an animated scene and a forecast line. /skies toggles it.

KOZMOS Storyboard: Claude narrates its own progress. A chapter tool the model calls at each phase change drives a band above the prompt: the chapter title, a five-stage rail (explore, plan, build, verify, ship) with the active stage glowing, step 3/5 and a note. /storyboard toggles the band, /storyboard log opens the chapter history.

KOZMOS Thrift: a frugal mode. /thrift on|off|auto; while on, every prompt carries a short note asking Claude to be economical (targeted reads, no broad searches or subagents unless needed, concise answers). Auto turns it on when the 5-hour or weekly limit passes autoAt and off after the window resets. A band with a spinning coin, and /thrift compares the average cost of thrift turns with...

KOZMOS Throttle: a car dashboard above the prompt. Speedometer of output tokens per second, fuel gauge of the 5-hour limit, temperature of the context, an odometer of session dollars, and check-engine, fuel and overheat lamps. /throttle toggles it.

KOZMOS Tidewater: the live diff of the current turn as tides above the prompt. Every file Claude edits gets its own pool of rolling waves, a green swell for added lines and a red ebb for removed ones, with file chips and totals like '+128 −42 · 6 files'. From the first edit of a turn until the next prompt. /tidewater toggles it.

KOZMOS Warpdrive: a starfield at warp above the prompt. Stars stream out of the center at the speed of Claude's live output token rate: a slow drift while it thinks, hyperspace streaks while it writes. When a turn ends, a jump flash and a line like '⇢ arrived · 42s · 18.4k tok'. /warpdrive toggles it.

TypeSafe's Jev decides how Claude Code works on each prompt: the main conversation's reasoning effort (low to xhigh, raised to max mid-turn when tool calls keep failing), each subagent's model, whether to split the work across subagents, and the one skill the prompt needs. Brings in custom OpenRouter models (a junior coder reviewed by Opus, or cheap bulk work) and Codex or OpenCode as...

Learns the short prompts you send often in this project and draws them, with the ones you pin by hand, above the prompt; with the prompt box empty, a digit key sends one at once.

An Improve button above the prompt (and /polish) rewrites your draft with Opus at low effort (/polish model picks another) using the prompt-master rules (MIT, nidhinjs/prompt-master); Undo puts the original back. Each press is one model call; its exact tokens are shown.

Shows you, above the prompt, the critical decisions the agent made without being asked: red to rethink, yellow to know, each with a rethink button. Works out of the box for any kind of project; /critical-areas auto lets the agent learn what is critical in yours.

Shows the prompt cache's countdown and hit rate above the input box, explains every cache break and cache expiry, and can keep the cache warm to cut Claude Code cost

The best all-in-one mod pack for Claude Code: a usage limits and context HUD, a guard with undo for rm -rf and git reset --hard, .env and secret protection, and a receipt for every turn.
