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 | $0.00806 | $0.00806 |
| Opus 5 | $0.00403 | $0.00403 |
| Sonnet 5 | $0.00161 | $0.00161 |
| Haiku 4.5 | $0.00081 | $0.00081 |
Grade A, and why
opendeck CLAUDE.md 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 10d 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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenDeck — contributor guide for Claude Code
OpenDeck turns a phone/tablet browser into a physical-feeling control deck for AI coding
agents. Read SPEC.md for the full product spec and DECISIONS.md for choices the spec left
open. Both are source-of-truth documents — update DECISIONS.md when you make a new call.
Commands
pnpm install # workspace install (Node >= 20, pnpm 11)
pnpm dev # hub in watch mode + deck dev server
pnpm build # all packages, topological
pnpm lint # eslint (typescript-eslint strict) + prettier --check
pnpm typecheck # tsc --noEmit in every package
pnpm test # vitest unit suites (protocol, hub, simulator, deck)
pnpm e2e # Playwright suites in e2e/ (build first)
pnpm perf # latency harness + bundle-size gate
Run single suites from a package: pnpm --filter @opendeck/protocol test, or a single file:
pnpm --filter opendeck test -- src/core/replay-buffer.test.ts.
Architecture map
packages/protocol zod schemas + types for every WS/REST message. Single source of truth.
Both hub and deck validate at the boundary. No runtime deps beyond zod.
packages/hub Node CLI + server (published to npm as `opendeck`).
src/cli.ts commander entry: default run, --demo, connect/disconnect, devices
src/core/ session registry, event bus, replay ring buffer
src/server/ fastify REST + static deck, ws fan-out, auth, pairing
src/adapters/ Adapter interface + claude (managed/observed), codex, simulator glue
packages/deck React 19 PWA (Vite + Tailwind v4 + zustand + motion; optional three.js face). Custom design
system from SPEC §7 tokens — no component library.
packages/simulator deterministic scripted fleet: demos, E2E, screenshots.
e2e/ Playwright projects (iPhone 14 / iPad / desktop) + latency harness.
Data flow: adapter → session registry → event bus → replay buffer → WS fan-out → deck store
→ widgets. The deck renders strictly from Session + events; harness-specific logic lives in
adapters only.
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.

opendeck CLAUDE.md is an instructions file published in the GitHub repository himanshudongre/opendeck (12 stars, last pushed 1mo ago), licensed MIT. It adds 806 tokens to every session, about $0.0040 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 2026-08-31.
