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.

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 | $0.00117 | $0.03447 |
| Opus 5 | $0.00059 | $0.01724 |
| Sonnet 5 | $0.00023 | $0.00689 |
| Haiku 4.5 | $0.00012 | $0.00345 |
Grade A, and why
langfuse-remote 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 9d 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 — 215 lines — stays where its author put it; the contents beside it link to each section on GitHub.
langfuse-remote
Stdlib-only Python 3 CLI for admin ops against any Langfuse instance (cloud or self-hosted). The binary lives in this plugin's bin/ and is auto-added to PATH when the plugin is enabled — call it as langfuse-remote.
Renamed from
langfuse→langfuse-remote(0.3.0) to disambiguate from the upstream Langfuse product. Matches the*-remoteconvention used across agent-plus plugins.
When to reach for this
- User wants to back up prompts from a Langfuse instance before changing / tearing it down.
- User wants to migrate prompts between instances (cloud → self-hosted, prod → dev, etc.).
- User wants to verify ingestion on a Langfuse instance after a deploy or config change — send a test trace and watch it land.
- User wants to check health of one or many Langfuse instances (uptime probe).
- User asks which Langfuse instances are configured / which one is active.
- User hands you a Langfuse user ID and asks what that user has been doing / where it went wrong / whether there are errors. Use
monitor-user— one JSON blob with metrics, sessions, latest trace + observation counts, and ERROR-level observations. - User hands you a trace / session / observation ID and asks you to fetch it. Use
get-traces/get-sessions/get-observations.
Do NOT use this to write new traces, evaluate prompts, or do anything that's a better fit for the Langfuse UI's dashboards. This is a control-plane / backup / migration / read-only-debug tool.
Configure
Four ways. Pick whichever fits — they stack (shell env wins, then --env-file, then auto-loaded .env, then JSON config).
0. Project .env auto-loading (portable default)
The CLI walks up from cwd looking for .env.local / .env. Any LANGFUSE_* keys it finds are loaded unless already set in the shell. This makes the skill "just work" when you run it from inside a project that already has Langfuse keys wired up for its own SDK (e.g. a .env with LANGFUSE_BASE_URL / LANGFUSE_PUBLIC_KEY / LANGFUSE_SECRET_KEY).
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.

langfuse-remote is a skill published in the GitHub repository osouthgate/agent-plus-skills (2 stars, last pushed 4mo ago), licensed MIT. It adds 117 tokens to every session and 3,447 once invoked, about $0.0006 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 2026-08-31.
