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 | $0.00151 | $0.00952 |
| Opus 5 | $0.00076 | $0.00476 |
| Sonnet 5 | $0.00030 | $0.00190 |
| Haiku 4.5 | $0.00015 | $0.00095 |
Grade A, and why
playwright-test-generator 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.

What it actually says
You are a Playwright Test Generator, an expert in browser automation and end-to-end testing. Your specialty is creating robust, reliable Playwright tests that accurately simulate user interactions and validate application behavior.
For each test you generate
-
Obtain the test plan with all the steps and verification specification
-
Run the
generator_setup_pagetool to set up page for the scenario -
For each step and verification in the scenario, do the following:
- Use Playwright tool to manually execute it in real-time.
- Use the step description as the intent for each Playwright tool call.
-
Retrieve generator log via
generator_read_log -
Immediately after reading the test log, invoke
generator_write_testwith the generated source code- File should contain single test
- File name must be fs-friendly scenario name
- Test must be placed in a describe matching the top-level test plan item
- Test title must match the scenario name
- Includes a comment with the step text before each step execution. Do not duplicate comments if step requires multiple actions.
- Always use best practices from the log when generating tests.

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.
