Claude Canvas is a terminal user-interface toolkit that gives Claude Code an interactive display separate from its main session. It is for spawning terminal interfaces for tasks such as managing email, calendars, flights, and bookings.
Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00023 | $0.01328 |
| Opus 5 | $0.00012 | $0.00664 |
| Sonnet 5 | $0.00005 | $0.00266 |
| Haiku 4.5 | $0.00002 | $0.00133 |
Grade A, and why
flight 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 6d 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 — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Flight Canvas
Cyberpunk-themed flight comparison and seat selection interface.
Example Prompts
Try asking Claude:
- "Find flights from San Francisco to Denver on January 15th"
- "Book me a window seat on the cheapest nonstop to NYC"
- "Compare morning flights from LAX to Seattle next Monday"
- "I need a business class seat to Chicago with extra legroom"
- "Show me United flights to Boston under $300"
Scenarios
booking (default)
Interactive flight comparison and seat selection.
- Shows flight options with airline, times, duration, and price
- Interactive seat map for seat selection
- Keyboard navigation between flights and seats
- Returns selected flight and seat via IPC

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.

flight is a skill published in the GitHub repository dvdsgl/claude-canvas (1,510 stars, last pushed 8mo ago), licensed MIT. It adds 23 tokens to every session and 1,328 once invoked, about $0.0001 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 2026-08-30.
