An installation command for a Pi observability project: a tool that records and displays what a coding agent does. It installs dependencies for the observability server, browser interface, and Steelman demo without starting servers.

Use it when setting up the project for the first time. It installs four packages, verifies Pi authentication, and prepares the default configuration.

It takes a fresh copy of the project to a ready-to-run state and checks required software and Pi login details. This avoids manually installing several packages or discovering missing setup later.

Token cost

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	$0.00050	$0.02256
Opus 5.5	$0.00020	$0.00902
Sonnet 5.5	$0.00010	$0.00451
Haiku 4.5	$0.00005	$0.00226

Security

Grade C, and why

install scanned grade C with 2 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 2mo 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.

Install pi-agent-observability

Purpose

Walk a fresh clone of pi-agent-observability from "just got pulled down" to "ready to run just all". This is an interactive, agentic process — ask the user when choices are needed, install what can be installed automatically, never start a long-running server.

Variables

PACKAGES: extension/, apps/observability/, apps/steelman/server/, apps/steelman/web/ — the four bun install targets PORTS: 43190 obs · 45210 Steelman API · 51730 Steelman web PI_AUTH_FILE: ~/.pi/agent/auth.json STEELMAN_MODEL: gemini-3.5-flash on provider google — the product agent's default, set via STEELMAN_AGENT_MODEL / STEELMAN_AGENT_MODEL_PROVIDER; needs GEMINI_API_KEY or pi /login ENV_SAMPLE: .env.sample — copy to .env to override any default

Instructions

Run every check via Bash — do not assume anything is installed.
Show a status line immediately after each check (✓ <thing> on pass, ✗ <thing> on fail).
Critical prerequisites (bun, pi, just) gate — if any is missing, stop and guide the user.
For auto-installable items (per-package bun install), install them without asking.
For items requiring user input, ask the user with a sensible default.
Do NOT read or display API key values — only confirm whether they're set.
Do NOT start any servers, daemons, or watchers. Verification is read-only.
Do NOT modify ~/.pi/agent/auth.json or ~/.pi/agent/models.json — those are user-scoped pi config.

install is a command published in the GitHub repository disler/pi-agent-observability (148 stars, last pushed 5mo ago), licensed MIT. It adds 50 tokens to every session and 2,256 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
