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 | $0.00095 | $0.03885 |
| Opus 5 | $0.00048 | $0.01943 |
| Sonnet 5 | $0.00019 | $0.00777 |
| Haiku 4.5 | $0.00010 | $0.00388 |
Grade A, and why
maintaining-dev-playground 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 today.
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 — 269 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Maintaining the Dev Playground
The Dev Playground (apps/client/src/dev/, accessible at /dev in development) is a living gallery of every visual component in DorkOS. It exists so that designers and developers can review components in isolation, catch regressions visually, and verify that the design system is coherent.
The playground is only useful if it stays in sync with the actual application. Stale or missing showcases erode trust and let regressions slip through. This skill exists to prevent that drift.
When This Skill Applies
Assess playground impact whenever you edit files in:
apps/client/src/layers/widgets/**/ui/**— widget UI componentsapps/client/src/layers/features/**/ui/**— feature UI componentsapps/client/src/layers/entities/**/ui/**— entity UI componentsapps/client/src/layers/shared/ui/**— shared UI primitivesapps/client/src/dev/**— direct playground edits
After editing a UI component, ask yourself three questions:
- Is this component a good playground candidate? (See candidacy criteria below)
- Is it already in the playground? Check the section registries in
dev/sections/. - If it's already there, is the showcase still accurate? Does it reflect the current props, states, and visual appearance?
Candidacy Criteria
A component belongs in the playground if it meets any of these:
- Visual and reusable — renders UI that appears in more than one place, or could
- Has multiple meaningful states — loading, empty, error, active, disabled, etc.
- Part of the design system — buttons, inputs, cards, badges, overlays
- A composed widget or panel — TasksPanel, MessagingConnections, TunnelDialog, etc.
- Complex enough to regress — more than trivial markup; has conditional rendering, animations, or data-dependent layout
A component does NOT belong if it's:
- Pure logic (hooks, utilities, stores) with no visual output
- A one-line wrapper that adds a className
- A layout container with no meaningful visual states
- A page-level route component (the playground itself IS the page-level view)
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.

maintaining-dev-playground is a skill published in the GitHub repository dork-labs/dorkos (9 stars, last pushed today), licensed MIT. It adds 95 tokens to every session and 3,885 once invoked, about $0.0005 per session on Opus 5. 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 2026-09-03.
