PenguinHarness is a local-first platform in which multiple AI agents create, evaluate, optimize, and deploy agent applications. It is for people building AI software who want agents to generate applications and improve their own behavior through skills.
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 | $0.00058 | $0.02435 |
| Opus 5.5 | $0.00023 | $0.00974 |
| Sonnet 5 | $0.00012 | $0.00487 |
| Haiku 4.5 | $0.00006 | $0.00244 |
Grade A, and why
company-setup 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 8d 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Company Setup
Company mode is the second work mode of PenguinHarness: a Project's Agents organized into a company — a CEO at the root of a reporting tree, one standing desk session per employee, a calendar as the only periodic driver, a ticket board that carries the work, channels where @ mentions interrupt, and monthly budgets that pause spending before it runs away. Creating one takes six facts and a single command.
This skill is how you collect those six facts and run that command. It ends there. You never hire, never schedule a calendar event and never file a ticket: creation produces the CEO and nothing else, and the CEO does the rest — after it has proposed a plan and the board (the humans of the Project) has answered.
Before you start
If the user's message only invokes this skill (e.g. "use company-setup skill") without naming a company to create, ask what organization they want and what it should do. One sentence is enough to start the questions below; do not create anything until every question has an answer and the user has said yes to the summary.
Look before the first question:
penguin org ls --json # the Project's organizations, so you never propose a taken id
If that call answers 404, company mode is off for this server (System settings › Server › Company mode). Say so and stop — nothing here can succeed until an admin turns it on.
Which Project the organization lands in
Inside a harness agent session every command subprocess carries PENGUIN_API_URL, PENGUIN_API_TOKEN and PENGUIN_PROJECT_ID, and penguin org create reads that last one as its --project-id — so you normally pass no flag and the organization is created in the Project you are running in. Check which one that is before you create anything:
echo "${PENGUIN_PROJECT_ID:-default_project}"
Name the Project in the summary. Pass --project-id <id> only when the user explicitly wants a different one.

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.

company-setup is a skill published in the GitHub repository Prism-Shadow/penguin-harness (2,386 stars, last pushed yesterday), licensed Apache-2.0. It adds 58 tokens to every session and 2,435 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-16.
