Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02976 | $0.02976 |
| Opus 5.5 | $0.01190 | $0.01190 |
| Sonnet 5.5 | $0.00595 | $0.00595 |
| Haiku 4.5 | $0.00298 | $0.00298 |
Grade A, and why
chronology-watchface AGENTS.md scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 250 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Chronology
A watchface with an analog dial whose rim sweeps through the screen at the current hour, configurable colors, and two dial styles (classic and large numerals). Two implementations share this repo:
pebble/— original Pebble version (C + Clay JS config)wear/— Wear OS version (Kotlin, androidx.wear.watchface)
Pebble (pebble/)
Run all Pebble commands from the pebble/ directory.
| Task | Command |
|---|---|
| Build | pebble build |
| Run on gabbro emulator | pebble build && pebble install --emulator gabbro && pebble logs |
| Screenshot all emulators | npm run screenshots |
| Install on phone | npm run install-phone |
Emulators
Target platforms: aplite, basalt, chalk, diorite, emery, gabbro
To run a specific emulator:
pebble install --emulator <platform>
pebble logs --emulator <platform>
pebble screenshot <output.png> --emulator <platform>
The SDK is installed per-user, not vendored. To set it up from scratch:
brew install uv && uv tool install --python 3.13 pebble-tool && pebble sdk install 4.33.1
gabbro needs 4.17 or newer; 4.9.169 predates it. The tool lands in
~/.local/bin, the SDK in ~/Library/Application Support/Pebble SDK/SDKs/.
If an emulator gets stuck at boot, wipe its flash:
pebble kill
rm ~/Library/Application\ Support/Pebble\ SDK/SDKs/4.33.1/<platform>/qemu_spi_flash.bin
Configuration
Settings are sent from the phone JS layer to the watch via Pebble.sendAppMessage. Persisted on the watch at these keys:
| Key | Message key | Persist key | Description |
|---|---|---|---|
BG_HEX |
10000 | 5 | Background color |
FACE_HEX |
10001 | 6 | Face color |
HAND_HEX |
10002 | 7 | Hand color |
FACE_CLEAR |
10003 | 8 | Transparent face toggle |
DIAL_STYLE |
10004 | 9 | 0 = classic, 1 = large numerals |
THICK_HAND |
10005 | 10 | Draws the hand one pixel wider |
To send a setting to a running emulator:
pebble send-app-message --emulator <platform> --int <message_key>=<value>
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
