god-build

god-build is a skill for Claude Code from hannsxpeter/godpowers. It costs 50 tokens per session (435 once invoked), scanned A, original, MIT.

A build skill that implements the next planned requirements with test-first development and records the final verification result. It can split independent slices among coding agents.

In plain words
What is it for?
It is for implementing PLAN.md slices, running targeted and full checks, updating the plan, and recording design decisions.
Why use it?
It provides a repeatable way to continue planned work while keeping tests, decisions, and progress records up to date.

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

god-build 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 10d 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

/god-build

  1. Read STATE.md and PLAN.md. Work from the next unchecked slice, the one the user named, or the requirements the request lists, kept under Goal in STATE.md. If there is none of these and the change is not trivial, run /god-plan first.
  2. For each slice or requirement:
    • Write or extend a test for its check and watch it fail, then make it pass with the smallest change that fits the existing code.
    • Run the targeted tests directly while you work; the recorded check comes once, at the end. Never weaken, skip, or delete a test to get green.
    • Tick the slice in PLAN.md, if there is one.
  3. Independent slices that touch different files can go to subagents of your choice, run however you prefer, one slice each, with the slice text, the files involved, and the verify command. Before you start each one, say which model and effort you picked for its slice and why, then pass both explicitly (whichever your host accepts); never let it inherit yours. Size both to the slice: a small, fast model at low effort for mechanical slices, a stronger model or higher effort only where the logic is tricky. Run the full check yourself after they return (step 5).
  4. Record lasting choices in DECISIONS.md as you make them. If a design choice turns out wrong, record the new decision and adjust the remaining slices.
  5. When every slice is done, record the project check once on the final code: npx -y godpowers@7 verify "<verify command>". Fix and re-run until it passes. Then set stage: review in STATE.md and suggest /god-review.
  6. Report what changed, the verify result, and what is left.

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.
