What it costs to keep this loaded
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 | $0.00000 | $0.05095 |
| Opus 5.5 | $0.00000 | $0.02038 |
| Sonnet 5.5 | $0.00000 | $0.01019 |
| Haiku 4.5 | $0.00000 | $0.00509 |
Grade A, and why
thurbox-ui-surfaces scanned grade A with 0 findings 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 9d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 310 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Thurbox keybindings, themes, settings and search
Working reference indexed by AGENTS.md. The rationale behind these decisions is owned by the docs under docs/; a change that invalidates what this says updates it in the same PR.
Keybindings
Every chord goes through one registry (kernel::registry). Plugins declare
keys in their declaration table; the kernel resolves a press to an action and hands
it back to the plugin that claimed it. There is no hardcoded table to keep in step
with a help screen, because the help modal renders the registry.
Global chords (kernel-owned):
| Key | Action |
|---|---|
Ctrl+Q |
Quit (detach sessions) |
Ctrl+N |
New session (the creation flow) |
Ctrl+H / Ctrl+L |
Focus previous / next pane |
Ctrl+J / Ctrl+K |
Select next / previous session |
Ctrl+, / F6 |
Settings (] for the Interface tab) |
Ctrl+Y / F4 |
Theme picker |
Ctrl+P |
Command palette — every action, filtered as you type |
F1 / Ctrl+G |
Keybindings help |
F10 |
Reload the interface from disk |
F12 |
Perf HUD |
Ctrl+C / Ctrl+V (+ Cmd+C / Cmd+V on macOS) |
Copy the selection / paste — copy only with [clipboard] copy_on_select = false; by default a drag's release copies and Ctrl+C is the interrupt |
Everything else belongs to a plugin and is listed in F1. Rebindings persist to
ui.json beside trust and the disabled set — a user decision, distinct from the
delivery facts in .bundled.json.
Reserved is not the same as kernel-owned. Five chords are handled before the
registry is consulted and cannot be rebound at all (registry::RESERVED: quit,
F10, Ctrl+H/Ctrl+L, F12) — they are the escape route out of a pane that
consumes every key. Everything else the kernel owns is an ordinary binding with
no Lua plugin behind it: the modal chords (kernel::modals::bindings) and copy
and paste (kernel::clipboard). Copy and paste used to be literal KeyCode
arms in the loop, which is why help listed them as fixed and a Mac user could
not put copy on Cmd+C (issue #1024). They resolve through the registry now,
ahead of a float's exclusive grab so they still work from any pane, and copy
declines the chord when there is no selection so Ctrl+C still interrupts the
agent.
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.

thurbox-ui-surfaces is a skill published in the GitHub repository Thurbeen/thurbox (115 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 5,095 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
