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.

SkillSpector: 5 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00064 | $0.02280 |
| Opus 5 | $0.00032 | $0.01140 |
| Sonnet 5 | $0.00013 | $0.00456 |
| Haiku 4.5 | $0.00006 | $0.00228 |
Grade A, and why
upgrade-browser-sdk-v6 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.

Upgrade Datadog Browser SDK to v6
Systematic migration guide from v5 to v6. Follow steps 1-6 in order. Each step includes a search pattern to find affected code.
Step 1: Update SDK version
CDN setup — update script src URLs:
| v5 pattern | v6 replacement |
|---|---|
datadoghq-browser-agent.com/us1/v5/datadog-rum.js |
datadoghq-browser-agent.com/us1/v6/datadog-rum.js |
datadoghq-browser-agent.com/us1/v5/datadog-logs.js |
datadoghq-browser-agent.com/us1/v6/datadog-logs.js |
datadoghq-browser-agent.com/us1/v5/datadog-rum-slim.js |
datadoghq-browser-agent.com/us1/v6/datadog-rum-slim.js |
Replace us1 with your site: eu1, us3, us5, ap1, ap2. For US1-FED, the pattern is flat with no site prefix: datadog-rum-v6.js, datadog-logs-v6.js, datadog-rum-slim-v6.js.
Search: grep -r "datadoghq-browser-agent.com.*v5" --include="*.html" --include="*.js" --include="*.ts" --include="*.tsx" --include="*.jsx"
npm setup — update package.json dependencies:
"@datadog/browser-rum": "^6.0.0"
"@datadog/browser-logs": "^6.0.0"
"@datadog/browser-rum-slim": "^6.0.0"
Then run your package manager (npm install, yarn install, etc.) and rebuild.
Also upgrade framework integrations to v6 if used: @datadog/browser-rum-react.
Search: grep -r "@datadog/browser-" --include="package.json" .
Step 2: Remove deprecated options
Removed from Core (affects both RUM and Logs)
| Option | Action |
|---|---|
useCrossSiteSessionCookie |
Replace with usePartitionedCrossSiteSessionCookie. |
Removed from Logs
| Option | Action |
|---|---|
sendLogsAfterSessionExpiration |
Delete. In v6, logs are always sent after session expiration (without a session ID). The option is no longer needed. |
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.
- 10d ago First seen · 162 lines · 64 tokens per session scan A 78ea8e9ea062
upgrade-browser-sdk-v6 is a skill published in the GitHub repository datadog-labs/agent-skills (168 stars, last pushed 14d ago), licensed MIT. It adds 64 tokens to every session and 2,280 once invoked, about $0.0003 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.
Other skills, from other repositories
next-cache-components-adoption
Turn on Cache Components in a Next.js app and resolve the blocking routes it surfaces. Use when the user wants to enable, adopt, or migrate to Cache Components, flip the cacheComponents flag, work through a flood of blocking-prerender / instant validation errors, run the cache-components-instant-false codemod, or…
next-cache-components-optimizer
Drive a Next.js route to instant navigation by setting up an agentic loop, under Cache Components / PPR, on initial load (hard navigation) and client-side navigation (soft navigation). Encode the goal as a failing @next/playwright instant() e2e and work it to green, one verified route at a time; the shipped test then…
next-partial-prefetching-adoption
Turn on Partial Prefetching in a Next.js app and work through the insights it surfaces. Use when the user wants to enable or adopt Partial Prefetching, flip the partialPrefetching flag, opt routes in with export const prefetch = 'partial', audit Link prefetch={true} behavior, preserve existing prefetched UI with…
next-dev-loop
Verify Next.js runtime behavior after editing app code. Use this skill to confirm a change actually works in a running app — not just that it compiles or type-checks. Combines /next/mcp (Next.js's view) with agent-browser (the browser's view). Requires a running next dev.
playwright-component-testing
Set up component testing with Playwright using a story gallery — scaffold stories and a gallery dev page driven by the built-in mount fixture, no dedicated component-testing runtime. Use when asked to test React or Vue components in isolation with Playwright, or to migrate off @playwright/experimental-ct-react / -vue.
a11y-debugging
Uses Chrome DevTools MCP for accessibility (a11y) debugging and auditing based on web.dev guidelines. Use when testing semantic HTML, ARIA labels, focus states, keyboard navigation, tap targets, and color contrast.
