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: 4 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 | $0.00075 | $0.03683 |
| Opus 5 | $0.00037 | $0.01842 |
| Sonnet 5 | $0.00015 | $0.00737 |
| Haiku 4.5 | $0.00007 | $0.00368 |
Grade A, and why
upgrade-browser-sdk-v5 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.

Upgrade Datadog Browser SDK to v5
Systematic migration guide from v4 to v5. Follow steps 1-7 in order. Each step includes a search pattern to find affected code.
Step 1: Update SDK version
CDN setup — update script src URLs:
| v4 pattern | v5 replacement |
|---|---|
datadoghq-browser-agent.com/us1/v4/datadog-rum.js |
datadoghq-browser-agent.com/us1/v5/datadog-rum.js |
datadoghq-browser-agent.com/us1/v4/datadog-logs.js |
datadoghq-browser-agent.com/us1/v5/datadog-logs.js |
datadoghq-browser-agent.com/us1/v4/datadog-rum-slim.js |
datadoghq-browser-agent.com/us1/v5/datadog-rum-slim.js |
Replace us1 with your site: eu1, us3, us5, ap1. For US1-FED, the pattern is flat with no site prefix: datadog-rum-v5.js, datadog-logs-v5.js, datadog-rum-slim-v5.js. Note: AP2 is not available for v5 — upgrade to v6 first if you need AP2.
Search: grep -r "datadoghq-browser-agent.com.*v4" --include="*.html" --include="*.js" --include="*.ts" --include="*.tsx" --include="*.jsx"
npm setup — update package.json dependencies:
"@datadog/browser-rum": "^5.0.0"
"@datadog/browser-logs": "^5.0.0"
"@datadog/browser-rum-slim": "^5.0.0"
Then run your package manager (npm install, yarn install, etc.) and rebuild.
Also upgrade framework integrations to v5 if used: @datadog/browser-rum-react.
Search: grep -r "@datadog/browser-" --include="package.json" .
Step 2: Replace deprecated init parameters
These v4 parameter names no longer exist in v5. Replace them:
| Deprecated parameter (v4) | Replacement (v5) |
|---|---|
proxyUrl |
proxy |
sampleRate |
sessionSampleRate |
allowedTracingOrigins |
allowedTracingUrls |
tracingSampleRate |

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.

upgrade-browser-sdk-v5 is a skill published in the GitHub repository datadog-labs/agent-skills (168 stars, last pushed 15d ago), licensed MIT. It adds 75 tokens to every session and 3,683 once invoked, about $0.0004 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.
