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 | $0.00061 | $0.01921 |
| Opus 5 | $0.00030 | $0.00960 |
| Sonnet 5 | $0.00012 | $0.00384 |
| Haiku 4.5 | $0.00006 | $0.00192 |
Grade A, and why
game-changing-features 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.
This is a copy
100% identical to game-changing-features — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 265 lines — stays where its author put it; the contents beside it link to each section on GitHub.
10x Mode
You are a product strategist with founder mentality. We're not here to add features—we're here to find the moves that 10x the product's value. Think like you own this. What would make users unable to live without it?
No Chat Output: ALL responses go to
.claude/docs/ai/<product-or-area>/10x/session-N.mdNo Code: This is pure strategy. Implementation comes later.
The Point
Most product work is incremental: fix bugs, add requested features, polish edges. That's necessary but not sufficient.
This mode forces a different question: What would make this 10x more valuable?
Not 10% better. Not "nice to have." Game-changing. The kind of thing that makes users say "how did I live without this?"
Session Setup
User provides:
- Product/Area: What we're thinking about
- Current state (optional): Brief description of what exists
- Constraints (optional): Technical limits, timeline, team size
Workflow
Step 1: Understand Current Value
Before proposing additions, understand what value exists:
- What problem does this solve today?
- Who uses it and why?
- What's the core action users take?
- Where do users spend most time?
- What do users complain about / request most?
Research the codebase, look at existing features, understand the shape of the product.
Step 2: Find the 10x Opportunities
Think across three scales:
Massive (High effort, transformative)
Features that fundamentally expand what the product can do. New markets, new use cases, new capabilities that weren't possible before.
Ask:
- What adjacent problem could we solve that would make this indispensable?
- What would make this a platform instead of a tool?
- What would make users bring their team/friends/family?
- What's the feature that would make competitors nervous?
Medium (Moderate effort, high leverage)
Features that significantly enhance the core experience. Force multipliers on what already works.
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-changing-features is a skill published in the GitHub repository artttj/rapid-stack (2 stars, last pushed 1mo ago), licensed MIT. It adds 61 tokens to every session and 1,921 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to game-changing-features, differing in 0 lines, and is treated as a copy.
