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 | $0.00029 | $0.01083 |
| Opus 5 | $0.00015 | $0.00541 |
| Sonnet 5 | $0.00006 | $0.00217 |
| Haiku 4.5 | $0.00003 | $0.00108 |
Grade A, and why
playwright-trace 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 11d 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.
This is a copy
97% identical to playwright-trace — 9 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Playwright Trace CLI
Inspect .zip trace files produced by Playwright tests without opening a browser.
Workflow
- Start with
trace open <trace.zip>to extract the trace and see its metadata. - Use
trace actionsto see all actions with their action IDs. - Use
trace action <action-id>to drill into a specific action — see parameters, logs, source location, and available snapshots. - Use
trace requests,trace console, ortrace errorsfor cross-cutting views. - Use
trace snapshot <action-id>to get the DOM snapshot, or run a browser command against it. - Use
trace closeto remove the extracted trace data when done.
All commands after open operate on the currently opened trace — no need to pass the trace file again. Opening a new trace replaces the previous one.
Commands
Open a trace
# Extract trace and show metadata: browser, viewport, duration, action/error counts
npx playwright trace open <trace.zip>
Close a trace
# Remove extracted trace data
npx playwright trace close
Actions
# List all actions as a tree with action IDs and timing
npx playwright trace actions
# Filter by action title (regex, case-insensitive)
npx playwright trace actions --grep "click"
# Only failed actions
npx playwright trace actions --errors-only
Action details
# Show full details for one action: params, result, logs, source, snapshots
npx playwright trace action <action-id>
The action command displays available snapshot phases (before, input, after) and the exact command to extract them.
Requests
# All network requests: method, status, URL, duration, size
npx playwright trace requests
# Filter by URL pattern
npx playwright trace requests --grep "api"
# Filter by HTTP method
npx playwright trace requests --method POST
# Only failed requests (status >= 400)
npx playwright trace requests --failed
Request details
# Show full details for one request: headers, body, security
npx playwright trace request <request-id>
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-trace is a skill published in the GitHub repository debs-obrien/playwright-movies-app (102 stars, last pushed 29d ago), licensed MIT. It adds 29 tokens to every session and 1,083 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 97% identical to playwright-trace, differing in 9 lines, and is treated as a copy.
