Personal telemetry
AI usage, in full
The complete view behind the homepage snapshot — how often I build with coding agents, when the work happens, and what shape it takes.
Collected automatically from local Claude Code and Codex transcripts on Antares Yuan's machines. Token counts and timings only; prompt and code content never leave the device.

Daily activity
One cell per day. Darker = more tokens.
Token mix
Fresh input vs cache reads vs output vs reasoning.
Working rhythm
Prompts by local weekday and hour — when the work actually happens.
Weekly trend
Total tokens per week, with a 4-week average.
Hour of day
Prompts per local hour, all days combined.
Day of week
Prompt share by weekday.
Session shape
Active minutes and message counts per day.
Tool mix
What the work consisted of — reading, editing, shelling out. Categories only; no tool or server names are collected.
By tool
Which coding agent produced the tokens.
By model
Private unless published — unlock below to view.
By project
Private unless published — unlock below to view.
Owner view
Paste the sync bearer token to load the private
/detail feed (per-model and per-project breakdowns). It stays in
this tab's sessionStorage and is sent only to the usage Worker.
Add a device
These numbers come from a small agent that reads local Claude Code and Codex transcripts and posts daily totals here. It's multi-device: each machine owns its own slot, so several Macs merge instead of overwriting.
Downloads just the agent into
~/.local/share/antares-usage, adds an antares-usage
command, then walks through setup. It detects installed tools, pins the
device slot, validates the shared bearer and shows a local dry run before
uploading anything. Re-running the installer is safe.
Then, any time:
- local breakdown, no network
- check config, secret and endpoint
- upload the latest totals now
Needs macOS (keychain + launchd) and Node. The bearer is
intentionally not on this page. Read it from a machine that already syncs with
security find-generic-password -a "$USER" -s antares-sync-usage -w.
Only token counts, timings and cost leave the machine; prompt and code content
never do. Full setup notes →
