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 | $0.00410 | $0.00410 |
| Opus 5 | $0.00205 | $0.00205 |
| Sonnet 5 | $0.00082 | $0.00082 |
| Haiku 4.5 | $0.00041 | $0.00041 |
Grade A, and why
skills AGENTS.md 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 3d 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
Ship Shit Games — Skills — Agent Instructions
This is the shipshitgames/skills repo: AI agent skills for vibe-coding 3D browser
games with Claude Code + Codex. Battle-tested live on the shipshitshow YouTube channel.

Cross-Agent Bootstrap
- Claude Code reads
CLAUDE.md, which delegates to this file. - Codex and other coding agents should follow this
AGENTS.md. - Cursor uses
.cursorignoreto keep generated files, lockfiles, and secrets out of indexed context. - Keep durable repo instructions here so all agents share one source of truth.
Rules
- Follow the Agent Skills spec:
.agents/SYSTEM/SKILL-STANDARDS.md namemust match the directory;descriptionstates WHAT + WHEN (front-load the use case)version/tagsgo inside themetadata:block as quoted strings, never top-level- No
auto_activate,auto_trigger, orriskfields - Every skill teaches the
@shipshitgames/engineconventions (imperative Three.js + theGameContext/GameSystemsregistry), grounded in the canonicalgames/scourge-survivors - Conventional commits (
feat:,fix:,refactor:,chore:); never commit secrets
Before editing skills
- Read the
SKILL.mdyou'll modify - Read
.agents/memory/MEMORY.mdfor repo decisions + the engine canon - Find a sibling skill and match its patterns
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.

skills AGENTS.md is an instructions file published in the GitHub repository shipshitgames/skills (2 stars, last pushed 1mo ago), licensed MIT.
