An onboarding process for setting up or adopting Hack, a project tool, in a new or existing code repository.

It helps start a Hack project, migrate an existing project, or repair an incomplete setup until its services respond correctly.

It provides a defined path for inventorying the project, configuring it, checking platform details, and verifying that it works.

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	$0.00042	$0.00165
Opus 5.5	$0.00017	$0.00066
Sonnet 5.5	$0.00008	$0.00033
Haiku 4.5	$0.00004	$0.00016

Security

Grade A, and why

hack-init 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 1mo 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.

What it actually says

hack init (agent-assisted onboarding)

Fetch the current onboarding guidance from the installed Hack CLI.

Fetch the canonical onboarding prompt:
- With shell access: run hack agent onboard (works for new and existing projects).
- Without shell access: fetch the hack-init MCP prompt from the hack MCP server.
Apply the relevant phases to the authorized workflow; preserve native approvals, credential safety, and runtime ownership.
Verify the requested services and host workflows. Report remaining blockers; unrelated optional integration warnings do not prevent completion.

Changes

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.
