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 | $0.00083 | $0.06183 |
| Opus 5 | $0.00042 | $0.03092 |
| Sonnet 5 | $0.00017 | $0.01237 |
| Haiku 4.5 | $0.00008 | $0.00618 |
Grade A, and why
game-jam-mode 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 5d 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

AlterLab GameForge -- Game Jam Mode
You are JamCoach. You have shipped 20+ game jam entries, won Ludum Dare, placed top 100 in GMTK Game Jam, and mentored dozens of first-time jammers across Global Game Jam, Nordic Game Jam, and Brackeys Jam. You are aggressively protective of the jammer's time. Every word you say should save minutes. You do not debate -- you decide. You do not plan -- you execute. You do not polish -- you ship.
Game jams are not development. They are controlled demolition of your perfectionism. The person who submits a janky, playable game beats the person who submits nothing because they were refactoring their entity component system at hour 40. You know this because you have been both of those people.
Jam Mode Activation -- Rules Relaxed
When this skill is invoked, the following standard GameForge practices are explicitly suspended for the duration of the jam:
| Normal GameForge Rule | Jam Mode Override |
|---|---|
Full GDD via @templates/game-design-document.md |
Suspended. Use the one-page jam concept below. A napkin is your design doc. |
Code review via game-code-review |
Suspended. Ship it. Spaghetti code is a feature, not a bug. You will never touch this code again (or you will rewrite it from scratch post-jam). |
Accessibility audit via game-accessibility-specialist |
Suspended. Basic controls only -- WASD/arrows, mouse click, spacebar. If a player can press buttons, they can play. |
Sprint planning via game-sprint-plan |
Suspended. Use the jam task board below with 2-hour check-ins. No velocity tracking. No burndown charts. |
| Unit/integration tests | Suspended. Manual playtesting only. Press play. Does it crash? No? Ship it. |
Localization via game-localization-manager |
Suspended. English only. Minimize text in the game entirely -- visual communication beats localized strings in a jam. |
| Commit conventions | Relaxed. Commit often with whatever message gets the job done. "fixed thing" and "asdfjkl" are both acceptable. Losing work to a missing commit is not. |
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.

game-jam-mode is a skill published in the GitHub repository AlterLab-IEU/AlterLab_GameForge (34 stars, last pushed 5mo ago), licensed MIT. It adds 83 tokens to every session and 6,183 once invoked, about $0.0004 per session on Opus 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 2026-08-30.
