What it does
Langfuse Previews is an agent skill from langfuse/langfuse. Use Langfuse's disposable per-PR previews at pr-N.preview.langfuse.com (synthetic data only). Use for preview access, failed deployments, test-data seeding, kubectl debugging, or waking sleeping previews.
Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in AI & LLM Engineering, covering LLM observability, Test data and fixtures and Deployment. It works with Langfuse and Kubernetes. The repository describes itself as: 🪢 Open source agent evals & observability: Trace, evaluate, and improve LLM applications with one open platform.
When your agent uses it
- Failed deployments
- Test-data seeding
- Kubectl debugging
- Waking sleeping previews
Example prompts
- “/langfuse-previews”
Requirements
- Docker
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Open ~/.aws/config and add the [sso-session langfuse] + [profile preview]
- aws sso login --profile preview
- aws eks update-kubeconfig --name langfuse-preview --region eu-west-1 --profile preview
What it can do on your machine
Read from SKILL.md and the folder at commit 8b58764. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
kubectlpnpmaws
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use kubectl, pnpm and aws, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
CLICKHOUSE_PASSWORD
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Langfuse Previews loads about 2.8k tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 1,248 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,248 words (~2,819 tokens).
“Every same-repo PR on langfuse/langfuse can get a disposable, full-stack Langfuse environment at https://pr-.preview.langfuse.com. Opening the PR builds a web + worker image; if your GitHub login is on the deploy allowlist, Argo CD (run from the private langfuse/infrastructure repo)…”
