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 | $0.00031 | $0.00661 |
| Opus 5.5 | $0.00012 | $0.00264 |
| Sonnet 5.5 | $0.00006 | $0.00132 |
| Haiku 4.5 | $0.00003 | $0.00066 |
Grade A, and why
playwright 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 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.
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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Browser Automation with Playwright
Use the playwright-cli.ts script bundled with this skill to automate web interactions and debug browser issues.
Run it with: tsx .agents/skills/playwright/cli.ts
When to Use
- Pages require interaction, authentication, or dynamic content loading (instead of read_web_page)
- Debugging browser automation errors (clicks not working, selectors failing, elements not found)
- Testing interactions before codifying them in source files
Commands
tsx .agents/skills/playwright/cli.ts open <url> # Launch browser and navigate to URL
tsx .agents/skills/playwright/cli.ts exec <code> # Execute Playwright TypeScript code
tsx .agents/skills/playwright/cli.ts snapshot # Save full-page PNG + HTML to tmp/playwright-screenshots/
tsx .agents/skills/playwright/cli.ts list # List open tabs
tsx .agents/skills/playwright/cli.ts close # Close the browser
The exec command provides access to: page, context, state, browser, snapshot
Example
tsx .agents/skills/playwright/cli.ts open https://example.com
tsx .agents/skills/playwright/cli.ts exec "await page.locator('button:has-text(\"Sign in\")').click()"
tsx .agents/skills/playwright/cli.ts exec "await page.fill('input[name=\"email\"]', '[email protected]')"
tsx .agents/skills/playwright/cli.ts snapshot
tsx .agents/skills/playwright/cli.ts close
Sessions & Profiles
Use --session <name> to run multiple isolated browser instances simultaneously.
Use save <domain> after logging in to persist cookies/localStorage for automatic reuse:
tsx .agents/skills/playwright/cli.ts open https://linkedin.com
# ... manually log in ...
tsx .agents/skills/playwright/cli.ts save linkedin.com
# Next time, profile is loaded automatically
Connecting to the Extension Debug Session
Launch the extension in a background tmux session with CDP enabled:
pnpm debug:extension # starts in tmux "opencode-debug", CDP on :9222
pnpm debug:extension --stop # stops the session
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

playwright is a skill published in the GitHub repository saffron-health/opencode-gui (58 stars, last pushed 1mo ago), licensed MIT. It adds 31 tokens to every session and 661 once invoked, about $0.0001 per session on Opus 5.5. 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.
