• Faithful Discord Live Preview — the preview now renders the real Rich Presence artwork (the Claude Code mascot and the Codex mark), bundled in-app and mapped by provider/surface, in a card that mirrors Discord's layout, with a Fast-tier ⚡ indicator.
• Plan override that sticks — a manual plan choice in Settings now persists to disk, reaches the live broadcast, and stays selected instead of snapping back to Auto-detect; the control uses a canonical plan-key contract.
• Live plan auto-detect — a Claude plan upgrade (e.g. Max 5x → Max 20x) is reflected without restarting Pulse.
• Codex Fast mode detected — the Codex service tier is read from ~/.codex/config.toml (where current Codex versions store it), so Fast renders as ⚡ … · Fast again.
• Clearer cost + cache UI — cost is reported per 1M tokens (the per-1K figure rounded to $0.00), and the dashboard cache grade shows a neutral — instead of a red F when there's no data yet.
• Hardened core — centralized the Claude plan mapping, bounded the session/report scans, and log previously-swallowed failures instead of dropping them.

You pay for Claude Code every month. Maybe $20 on Pro, $100 – $200 on Max, or a seat on Teams. And yet, if someone asked "which of your sessions burned the most context this week?" or "what percentage of your tokens are actually cache hits?" — you probably can't answer.

Pulse answers. It reads Claude Code's own JSONL transcripts (zero-config — just install and launch) and surfaces the things that actually move the needle on your plan:

• A – F cache-health letter grade — trend-weighted, so you see the direction your cache efficiency is heading, not just today's number.
• Opus-4.7-tokenizer aware — Opus 4.7's new tokenizer inflates tokens by up to 35 %; Pulse flags the inflation so you know when you're hitting limits faster than expected.
• 1 M context GA pricing — flat per-token rate across the full 1 M window for Fable 5 · Mythos 5 · Opus 4.6 · Opus 4.7 · Opus 4.8 · Sonnet 4.6 (per Anthropic's official pricing). Older betas (Sonnet 4 / 4.5, Opus 4 / 4.5) still get 2× input · 1.5× output · 2× cache at > 200 K. Pulse applies the correct math per-model so you compare sessions like-for-like. Plan-level Extra Usage on Pro / Max / Teams is tracked separately.
• Inflection alerts — any session that blows past 2 × your rolling baseline gets flagged with context and a suggested fix.
• Fix-with-Claude prompts — every recommendation has a Copy Fix Prompt button. Paste it into Claude Code. Problem fixed.
• Plan usage limits — live tracking of your 5-hour window, weekly, Sonnet-only, and Extra Usage quotas. Sound alert when Extra Usage spikes.
• Release awareness — startup and 6-hour update checks surface new stable GitHub Releases inside the app without pretending a signed auto-installer exists before release metadata is published.
• Discord Rich Presence — five-tier reasoning effort, live project / model / branch. Your flow state, on your profile.

Works with OpenAI Codex too. Flip the provider toggle and Pulse reads your Codex CLI sessions the same way — per-model pricing for the GPT-5 family including GPT-5.5 ($5 / $30 per Mtok), 400 K context tracking, and reasoning-effort detection. Fast mode (/fast) is priced correctly on both sides: Codex GPT-5.5 bills at 2.5× and GPT-5.4 at 2× the standard rate, and Claude Opus 4.8 Fast bills at 2× — each flagged with a ⚡ marker in Sessions and Discord presence.

Codex Discord Rich Presence has its own source-of-truth repo: xt0n1-t3ch/Codex-Discord-Rich-Presence. Pulse mirrors that Rust core into src/codex/ through checked sync scripts and CI freshness gates, so Codex support can move fast here while the standalone Rich Presence project keeps its own audience.

Analytics dashboard

Accurate cost math	Per session · day · model. Published pricing for every Claude — Fable 5, Mythos 5, Opus 4.8 (with fast mode), 4.7, 4.6, 4.5, 4.1, 4, 3; Sonnet 4.6, 4.5, 4; Haiku 4.5, 3.5, 3. Speed-aware per-turn, so fast turns price at 2×. Compare like-for-like whatever plan you're on.
A – F cache health grade	Trend-weighted hit ratio — cchubber-style. See your direction, not just your current number.
Model routing insights	Opus / Sonnet / Haiku split + "you could save $X by rerouting N sessions to Sonnet" estimate.
Inflection detection	Any session ≥ 2 × baseline cost-per-session gets flagged with context.
Recommendations engine	Every finding has a Copy Fix Prompt button. Paste it into Claude Code. Problem fixed.
Plan usage limits	5-hour window · weekly all-models · Sonnet-only · Extra Usage monthly spend. Auto-detects Pro / Max / Teams. Sound alert on Extra Usage spikes.
Heatmap · sparklines · charts	All-local Chart.js. Zero network.
Reports export	Branded HTML + Markdown. One click.
OpenAI Codex support	Full GPT-5 family pricing — GPT-5.5, 5.4, 5.3-Codex, 5.2, 5.1 (+ Codex / max / mini), 5, mini, nano. Fast mode (/fast) surfaced at 2.5× (5.5) / 2× (5.4). One-click provider switch.
Codex RP upstream sync	Codex Discord Rich Presence logic is mirrored from Codex-Discord-Rich-Presence with scripts and CI checks, instead of drifting as a private fork.

Discord Rich Presence

Live fields	Project · git branch · model · reasoning effort · activity status.
Session timer	Elapsed since start. Persists through Discord restarts.
Reasoning tiers	Five tiers (Low / Medium / High / Extra High / Max) — Opus 4.7 native.
Asset resolver	Multi-tier — portal keys → Media Proxy → plain URLs → fallback.
Presets	Minimal · Standard · Full. Customize per-field too.

First launch → install Pulse → launch → it auto-detects your ~/.claude/ folder → keep using Claude Code; sessions stream in live.

Discord Rich Presence → open the Discord tab → pick a preset (Minimal · Standard · Full) or customize fields → toggle on. Custom presence artwork in docs/discord-assets.md.

Reports → open the Reports tab → read your cache grade + recommendations → click Copy Fix Prompt on any item → paste into Claude Code → done. Export HTML / Markdown for your team.

• Linux tray icon — system-tray quick toggles (Discord presence on/off, pause analytics, open dashboard) via Tauri's tray-icon feature. Parity with the Windows tray.
• MCP server inventory — list every MCP server Claude Code has loaded for each session, with its tool count, per-tool invocation frequency, and an estimated token cost per tool call. Helps spot noisy MCPs silently inflating your context.
• Budget-threshold desktop notifications — native OS notification when you cross configurable thresholds (e.g. "80 % of weekly limit", "Extra Usage just passed $150 of your $200 cap"). Replaces eyeballing the dashboard.
• Custom Discord presence templates — save / share named field layouts beyond Minimal · Standard · Full. Export a preset as JSON; import one from a teammate.
• Session replay — step through a past session's prompts and tool-call timeline with the same filters the live dashboard uses. Currently the data is there (JSONL traces) but there's no dedicated UI.
• Smarter cost forecast — weekly-reset-aware projections with a confidence band, instead of today's linear daily-average multiplication.

Windows + WSL session roots

Pulse is Windows-native by default. On Windows it does not launch wsl.exe while polling sessions, because broken WSL installs can raise OS-level crash dialogs. If you intentionally keep Claude/Codex transcripts inside WSL and want Pulse to scan them, opt in before launch:

$env:CC_PRESENCE_INCLUDE_WSL = "1"

Linux and macOS continue to use their native session paths; WSL path bridging remains available only through the explicit Windows opt-in.
