Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
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 | $0.00026 | $0.00896 |
| Opus 5 | $0.00013 | $0.00448 |
| Sonnet 5 | $0.00005 | $0.00179 |
| Haiku 4.5 | $0.00003 | $0.00090 |
Grade A, and why
tuturuuu-browser-vercel-debugging 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 2d 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 — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tuturuuu Browser And Vercel Debugging
Core Workflow
Use browser evidence and Vercel evidence as two views of the same request:
- Identify the owning app, domain, workspace, route, deployment, and expected behavior.
- Reproduce with the authenticated browser session the user supplied.
- Capture the final URL, visible state, console errors, failed requests, timestamps, status codes, and request IDs without exposing secrets or customer records.
- Use the Vercel CLI to resolve the alias to a deployment and query a bounded runtime-log window for the same host, route, time, status, or request ID.
- Trace the owning route and authentication boundary in source. Add a focused regression test before changing behavior when practical.
- Patch the smallest owning surface, run focused validation, and only claim production verification after the fix is deployed.
Read references/production-debugging-playbook.md for browser selection,
Vercel CLI commands, common Tuturuuu failure signatures, performance/cost
investigation, and product-improvement checks.
Production Safety
- Keep production browser and Vercel work read-only by default.
- Do not create, edit, delete, submit, approve, invoice, attend, move, or bulk update production data unless the user explicitly authorizes that mutation.
- When mutation is required, prefer a test-owned or personal workspace and clearly identify cleanup responsibility. Never reuse customer records as test fixtures.
- Never print cookies, authorization headers, session tokens, environment values, raw customer payloads, or private logs. Report environment variable names and sanitized metadata only.
- Do not use
vercel deploy, project removal, alias changes, environment mutation, rollback, or promotion commands unless the user explicitly asks. - Bound log queries with
--since,--until,--limit, route/status filters, or a request ID. Use--followonly for an explicit monitoring task.
Browser Selection
What ships with it
2 files 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.

tuturuuu-browser-vercel-debugging is a skill published in the GitHub repository tutur3u/platform (53 stars, last pushed today), licensed Apache-2.0. It adds 26 tokens to every session and 896 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 2026-09-03.
