## pi-langfuse — LLM Observability for Pi
|
||||
|
||||
Sends pi's LLM traffic to Langfuse (self-hosted on .13:3001) for tracing, token usage, and cost-per-session. One trace per user prompt, grouped by pi session.
|
||||
|
||||
| Aspect | Detail |
|
||||
|--------|--------|
|
||||
| **What it is** | pi extension (npm package `pi-langfuse` v1.5.8, by gooyoung) that captures pi runs — agent steps, LLM generations, tool calls, final output, usage, cost — into Langfuse |
|
||||
| **Where it runs** | Per-project — enabled by adding `npm:pi-langfuse` to `<project>/.pi/settings.json` `packages`. Keys read globally from `~/.pi/agent/pi-langfuse/config.json` |
|
||||
| **Config file** | `~/.pi/agent/pi-langfuse/config.json` (mode 600): `{ "publicKey": "pk-lf-…", "secretKey": "sk-lf-…", "host": "http://192.168.20.13:3001" }` |
|
||||
| **Env var fallback** | `LANGFUSE_PUBLIC_KEY`, `LANGFUSE_SECRET_KEY`, `LANGFUSE_BASE_URL` (used only when config.json is missing/incomplete) |
|
||||
| **Commands** | `/langfuse-setup` (interactive key entry), `/langfuse-status` (show config state, masked keys, capture policy) |
|
||||
| **Requirements** | Node ≥ 22 (machines run 24); peer dep `@earendil-works/pi-coding-agent: *` |
|
||||
| **What you get** | Root `agent`, per-request `generation`, and per-tool `tool` observations; token usage + cost; privacy controls (input/output/tool redaction, path hashing, secret redaction) |
|
||||
| **Dashboard** | `http://192.168.20.13:3001` |
|
||||
|
||||
### Install (per project)
|
||||
|
||||
Add to the project's `.pi/settings.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"packages": ["npm:pi-langfuse"]
|
||||
}
|
||||
```
|
||||
|
||||
Restart pi — it installs the extension into `.pi/npm/` and picks up the config automatically.
|
||||
|
||||
### Global install (all projects / machines)
|
||||
|
||||
The global `~/.pi/agent/settings.json` is a Nix-store symlink (read-only). To enable everywhere, add `npm:pi-langfuse` to the `packages` list in `/etc/nixos/home/sam/home.nix` and rebuild Home Manager.
|
||||
|
||||
### Why not the OmniRoute langfuse plugin?
|
||||
|
||||
OmniRoute's example langfuse plugin is **broken against the 3.8.48 runtime** (verified in source, 2026-08-03):
|
||||
- Plugin config is stored in SQLite but **never delivered to hook payloads** — `PluginContext` has no `config` field
|
||||
- `onRequest` metadata is **not threaded** to `onResponse` (each hook gets a fresh `metadata: {}`)
|
||||
- **Streaming requests** (what pi uses) receive `response: { status: 200, streamed: true }` — no response body to trace
|
||||
|
||||
pi-langfuse traces at the pi layer instead, which works for streaming and gives per-session grouping. The plugin files were removed from .13 (compose restored, container recreated clean).
