Context Inspector

A 128K window, 70K of it spoken for. The bar is the composition, the list is the legend: hover or Tab through a row and its slice lights up while the rest dim. 22.4K is marked evictable — flip 'Preview without evictable' to see what dropping it would give back; the scale stays pinned to the real total, so the freed hatch shows up as space, not as a redrawn chart. Nothing is ever removed: the inspector reads the prompt, it doesn't edit it.

Three hundred turns later. Used is 121,990 of 128,000, which leaves 6,010 for a reply that reserves 8,000 — the headroom band switches to the alarm hatch and the notice names the shortfall and the way out. History carries 74.3K that was never itemised; expanding it says so instead of quietly showing eight turns as if they were the whole thing.

74.3Ktokens in this section aren't itemised — counted in the total, not broken down.

Past the window entirely. The bar's scale grows with the overflow so the window edge moves left instead of the fill being clipped — the amount you are over stays measurable. Here the evictable third is enough to fix it, and the notice says so rather than just going red.

Over the window by 5,990 tokens — this prompt cannot be sent, and there is no room left for a reply. Dropping the 22.4K evictable tokens would bring it back to 111.6K — inside the window. Preview it first.

The shapes that break naive panels: 24 MCP schemas capped at 5 rows with an explicit 'Show 19 more', a 119-character file path that wraps instead of widening the card, a 'Cached prefix' section that has a total but no breakdown (so its row is not a fake disclosure), and a 60-token scratchpad worth 0.05% that still keeps a visible sliver and prints '<0.1%' instead of '0%'.

limit={0} — no window configured. There is nothing to be full of, so the percentages are shares of what is there, the reply band and the limit line are not drawn at all, and the panel still answers 'what is in this prompt'. itemOrder='given' keeps your order instead of putting the largest entry first.

status='ready' — the same healthy window as above, straight from the mock's ready envelope: the bar, the arithmetic and every section.

status='empty' — the prompt hasn't been assembled yet, so the window is genuinely empty rather than unknown.

The window is empty

Nothing has been assembled into the prompt yet — no system instructions, tools, files or history.

128K-token window, all of it free.

status='loading' — the bar and the section rows are shaped like what replaces them, so nothing jumps on arrival.

status='error' — the tokenizer never reported back. Different from a full window: what's inside is unknown, so nothing is drawn.

Couldn't read the context window

The tokenizer didn't report back, so what the prompt contains is unknown.
