Cached by `(path,size,mtime)`; recency-capped 30d/50 sessions. Frontend: `src/lib/usage.ts` holds the editable pricing table (per-MTok, matched by opus/sonnet/haiku substring) + cost/format helpers; `UsagePanel.tsx` (MCP-panel modal pattern) lists sessions, highlights those whose transcript `cwd` matches an open pane (`[pane: label]`); titlebar 💰 total chip; App polls 20s (visible) / 5s (panel open); **Ctrl+Shift+U** opens it. **Design choice:** session-list attribution (not 1:1 pane binding) — avoids the unsolvable "2 claudes in one cwd" ambiguity. **Caveats:** cost is an estimate (cache-creation priced at 5m rate; rates hardcoded, may drift); panes with no explicit cwd (`~`) won't highlight; PowerShell/SSH show nothing. Plan: `~/.claude/plans/greedy-cooking-flask.md`. - **PIVOTED 2026-05-28 → per-pane context-fill indicator (replaces the panel).** User decided lifetime token totals + $ aren't worth it on a subscription; what's actionable is *current context-window occupancy* per pane (spot the one needing `/compact`). Removed `UsagePanel`, the 💰 titlebar chip, and `Ctrl+Shift+U`. Repurposed `usage.rs`: `get_pane_context` returns each recent session's **current** occupancy = the LAST assistant turn's `input + cache_read + cache_creation` tokens (verified ~274k on this 1M session). `src/lib/usage.ts` now does window inference (200k vs 1M by whether occupancy already exceeds 200k — model id doesn't encode the variant), %, color ramp. App polls 15s (visibility-gated) → `cwd→SessionContext` map via orchestration; `LeafPane` renders a slim fill bar + % in the header, matched by `leaf.cwd`. **Also fixed narrow-pane toolbar** (user report: close × clipped when slim): a `ResizeObserver` in LeafPane sets `leaf--narrow`/`leaf--xnarrow` tiers; label shrinks first, split/status/secondary chips drop by tier, close × + context indicator stay pinned-right + visible down to the 180px min. Plan: `~/.claude/plans/greedy-cooking-flask.md` (rewritten for the pivot). **Pending Windows runtime verify.** Window-size 200k/1M is inferred (approx near boundary); `~`-spawned / cd'd panes may not match their session. - **Windows test 2026-05-28:** narrow-pane toolbar reflow (close × stays visible when shrunk, leaf--narrow/xnarrow tiers) **VERIFIED working.** BUT the context bar **does not show** — root-caused: it keys on `leaf.cwd`, which is ~always `undefined` (`newLeaf` sets no cwd; the shell picker never supplies one; only split-inheritance propagates it). So the cwd↔transcript match never hits for normal panes. Needs the pane's *live* cwd to work — leading options: capture via OSC 7 (default WSL bash under tiletopia doesn't emit it → would need injecting a PROMPT_COMMAND at spawn, shell-specific), or an "active pane shows its distro's currently-active session" heuristic gated on recent mtime. Decision pending with user. + - **Fix implemented 2026-05-28 (OSC 7 live cwd, user chose this) — PENDING re-test.** `pty.rs` Wsl arm now sets `PROMPT_COMMAND` (forwarded via `WSLENV=…:PROMPT_COMMAND/u`) to `printf '\033]7;file://%s%s\033\\' "$HOSTNAME" "$PWD"` so the shell emits OSC 7 each prompt; default Ubuntu bash inherits an env-provided PROMPT_COMMAND (a hard-assigning rc or non-bash shell won't report → bar hidden, no breakage). `XtermPane` registers `term.parser.registerOscHandler(7, …)`, decodes the path, fires new `onCwd` prop. `LeafPane` tracks `liveCwd` and matches on `(liveCwd ?? leaf.cwd)`. OSC 7 fires at the bash prompt right before `claude` launches → `liveCwd` = claude's launch cwd; also follows `cd`. **If still blank after re-test:** check the shell actually emits OSC 7 (it won't if the user's rc hard-sets PROMPT_COMMAND, or default shell isn't bash) and that backend `get_pane_context` returns sessions (UNC/$HOME probe). - **Superseded — original lifetime-token panel refinements (kept for history):** (1) **Scope** — panel + titlebar chip now default to sessions matching open panes ("this workspace"), with an "open panes / all recent" toggle. The first cut summed *every* recent session on the distro (all projects, `/mnt` + home), which read as inflated. **Investigated the "double counting mounted folders + projects" report: NOT a real double count** — every transcript file is read exactly once, and no two project dirs share a cwd because claude resolves symlinks/mounts to the real path before mangling the project-dir name (e.g. the `~/claude/projects/tiletopia → /mnt/d/dev/tiletopia` symlink yields only `-mnt-d-dev-tiletopia`). The inflation was purely the global scope. (2) **Metric framing** — user is on a Pro/Max subscription where $ is meaningless (and `/usage` rate-limit quota can't be derived from transcripts); **tokens are now the headline**, the API-cost estimate is a labeled secondary `~$` kept visible so the user can validate it against real API billing at work. **Open question:** accuracy of the $ estimate vs actual API billing — user will check at work. - [ ] **Smart link providers.** `terminal.registerLinkProvider()` to make file paths (`src/foo.ts:12:3`), `localhost:PORT`, and error locations clickable — more flexible than the regex-only web-links addon already loaded. Open file in editor / browser. Difficulty: medium. - [x] ~~**Find in scrollback.**~~ Done + **verified on Windows 2026-05-28** — `@xterm/addon-search` + new `src/components/SearchBar.tsx`/`.css` overlay, Ctrl+Shift+F open / Enter / Shift+Enter / Esc, regex + case toggles, decoration highlight.
