install

A setup command for installing and checking the Pi Verifier Agent on a fresh code copy. It checks required runtime tools, packages, verifier instructions, and an LLM provider API key without opening an interactive session.

In plain words
What is it for?
Use it to prepare a fresh checkout for the Pi Verifier Agent and install what can be installed automatically while asking about choices such as which API key to use.
Why use it?
It gathers the setup checks in one guided process, so missing tools, dependencies, or configuration are found before development starts.

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.

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.

Security

Grade A, and why

install scanned grade A with 1 finding 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 2d 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.

Asks the agent to reveal its instructionslowSystem prompt leakage

Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.

- `[ -f .pi/verifier/prompts/verify_on_stop.md ] && echo prompt-template-present`

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Install Pi Verifier Agent

Purpose

Set up the Pi Verifier Agent for development on a fresh clone. Walks the user through every check the system needs — runtime tools (node / tmux / pi), TypeScript dependencies, the verifier persona, and an LLM provider API key — without ever starting an interactive Pi session. Interactive: ask the user when a choice is needed (e.g., which API key to set), install what can be installed automatically.

Variables

SOURCE_REPO: The repo root this command runs from APP_DIR: apps/verifier/ PERSONA: .pi/verifier/agents/verifier.md PROMPT_TEMPLATE: .pi/verifier/prompts/verify_on_stop.md SETTINGS: .pi/settings.json

Instructions

  • Run every check via Bash — do not assume anything is installed.
  • Show a one-line pass/fail status after each check.
  • Critical deps (node, pi, tmux) gate the install — stop and instruct the user if missing.
  • For the API key step: confirm a provider key is set in either process.env or .env. Never read or print key values — only confirm presence.
  • Do NOT start pi, do NOT run just verifier, do NOT open windows — this command verifies readiness only.
  • If a .env doesn't exist, offer to create one with the chosen provider's key as a placeholder (commented), but never write a real key.

Workflow

Step 1 — Critical prerequisites (gate)

If any of these are missing, stop and instruct the user before continuing.

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.

install is a command published in the GitHub repository AojdevStudio/hermes-satellite (2 stars, last pushed 10d ago), licensed MIT. It adds 16 tokens to every session and 1,844 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (asks the agent to reveal its instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
