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 | $0.00049 | $0.00936 |
| Opus 5.5 | $0.00020 | $0.00374 |
| Sonnet 5.5 | $0.00010 | $0.00187 |
| Haiku 4.5 | $0.00005 | $0.00094 |
Grade A, and why
kc-screenshot 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.
curl -sf http://localhost:7070/ >/dev/null && echo "dev server up" || tail -20 /tmp/dev_server.log How it starts
The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Screenshot the dashboard SPA
Drives a headless Chromium across desktop (1280x800) and mobile (390x844) viewports in dark + light themes, against a local dev harness that stubs auth. Useful for changes that can't be fully unit-tested (terminal iframe, layout, theming). Read the resulting PNGs with the Read tool — they render inline.
How it works
charts/workspace/web/dev_server.py <port>— a thin harness that imports the realcharts/workspace/server.pyand monkeypatchescheck_claude_authto always return True, so the SPA can hit/api/*without the OAuth proxy. The production dashboard on 6080 is untouched.charts/workspace/web/scripts/shoot.mjs— drives Chromium viaplaywright-coreand writesphaseN-<view>-<viewport>-<theme>.pngfiles. Sibling variants exist for specific surfaces:shoot-hv.mjs(hypervisor),shoot-msgchat.mjs,shoot-docs.mjs,shoot-toolbar-paste.mjs.
Steps
1. Build the SPA (the dev server serves dist/)
yarn --cwd charts/workspace/web build
Rebuild after any source edit — the dev server picks up the new dist/ on the
next request, no restart needed.
2. Start the dev server on port 7070
cd /home/dev/kube-coder
nohup python3 charts/workspace/web/dev_server.py 7070 > /tmp/dev_server.log 2>&1 &
disown
sleep 2
curl -sf http://localhost:7070/ >/dev/null && echo "dev server up" || tail -20 /tmp/dev_server.log
3. Ensure a Chromium binary is installed
The shoot scripts auto-discover the Playwright Chromium via
scripts/chromium-path.mjs (checks $KC_CHROMIUM, then the highest-revision
chromium-<rev> under any ms-playwright cache root), so you don't hardcode or
symlink anything. Just make sure one is installed:
ls -d ~/.cache/ms-playwright/chromium-*/chrome-linux*/chrome 2>/dev/null \
|| yarn --cwd charts/workspace/web exec playwright install chromium
If it lives somewhere unusual, point the scripts at it explicitly with
KC_CHROMIUM=/path/to/chrome.
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.

kc-screenshot is a skill published in the GitHub repository imran31415/kube-coder (399 stars, last pushed 2d ago), licensed MIT. It adds 49 tokens to every session and 936 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
