What is diff-invaders?

A Space Invaders arcade game displayed above the Claude Code prompt, using lines of code Claude has added as the invading formation.

It is for shooting through a visual version of Claude’s code changes in an interactive terminal. It requires function hooks and an interactive terminal.

It gives you something to play while Claude works, without using extra model tokens. It pauses when the turn ends and turns the current code changes into the game’s targets.

Security

Grade A, and why

diff-invaders 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 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.
