What it does
Security Review is an agent skill from langfuse/langfuse. Review Langfuse changes for SSRF, tenant isolation, secret handling, unsafe redirects or uploads, RBAC drift, and client telemetry privacy. Use when a design or change accepts URLs or host fields, handles secrets or cross-tenant data, makes outbound requests, adds an integration, follows redirects, widens permissions, or can send customer-controlled UI data through analytics, monitoring, or session replay.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/checklist.md`, `references/client-telemetry-privacy.md` and `references/outbound-url-validation.md`).
It sits in Security, covering Security review, LLM observability and Web application vulnerabilities. It works with Langfuse. 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
- Change accepts URLs
- Handles secrets
- Cross-tenant data
- Makes outbound requests
Example prompts
- “/security-review”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Open references/checklist.md and run the mental
- For each bullet that fires, open the matching topic reference.
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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Security Review loads about 1.4k tokens when it runs, and up to ~7k if it reads all its reference files. Until then it costs about 106 tokens; SKILL.md has 612 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
Auto-check passed
The automated check found no risky patterns in SKILL.md.
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 612 words (~1,422 tokens).
“Use this skill when reviewing or planning code that touches a security-sensitive surface in Langfuse. It collects the recurring findings the team has seen in external security reports so that future agents catch them at design and review time rather…”

Review Langfuse changes for SSRF, tenant isolation, secret handling, unsafe redirects or uploads, RBAC drift, and client telemetry privacy.
When should I use Security Review?
Security Review fits situations like: change accepts URLs; handles secrets; cross-tenant data; makes outbound requests.
How do I install Security Review in Claude Code?
Run `npx skills add langfuse/langfuse --skill security-review -a claude-code`. Or copy the skill folder (.agents/skills/security-review in langfuse/langfuse) into .claude/skills/security-review in your project. Claude Code loads it when a task matches its description.
How do I install Security Review in Codex?
Run `npx skills add langfuse/langfuse --skill security-review -a codex`. Or copy the skill folder (.agents/skills/security-review in langfuse/langfuse) into .agents/skills/security-review in your project. Codex loads it when a task matches its description.
Can I use Security Review in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add langfuse/langfuse --skill security-review -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/security-review, .gemini/skills/security-review, .github/skills/security-review and .opencode/skills/security-review in your project.
What does Security Review need to run?
SKILL.md names no scripts, command-line tools or credentials: Security Review is instructions for the agent only.
Does Security Review access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Security Review safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Security Review use?
Security Review has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Security Review use?
About 1.4k tokens (SKILL.md is roughly 5.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 5.6k tokens, read only when the agent opens those files.
