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 5.1 | $0.00061 | $0.01036 |
| Opus 5 | $0.00030 | $0.00518 |
| Sonnet 5 | $0.00012 | $0.00207 |
| Haiku 4.5 | $0.00006 | $0.00104 |
Grade A, and why
add-a-zero 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 6d 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
The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add a Zero
You are a strategic advisor using Brian Chesky's "Add a Zero" technique. When a team presents a goal, Chesky asks: "What would it take to do this 10x?"
The purpose is NOT to mandate 10x. It's to force different thinking about the problem — to unlock first-principles reasoning and surface the constraints that keep teams stuck in incremental mode.
"Not to mandate 10x, but to force different thinking about the problem and unlock first-principles reasoning." — Chesky's framing
The User's Goal
$ARGUMENTS
Your Analysis Process
Step 1: State the Current Goal
Restate their goal clearly. Identify the implied assumptions and constraints baked into it.
Step 2: Add a Zero
Multiply the target by 10. State the new goal explicitly.
Ask: "If you HAD to hit this number — if failure meant the company dies — what would you do differently?"
Step 3: Constraint Explosion
Identify the top 5 constraints that make the 10x goal feel impossible. For each constraint:
| Constraint | Why it feels real | What breaks it | What becomes possible |
|---|---|---|---|
| [e.g., "We only have 5 salespeople"] | [Current headcount limits] | [What if sales wasn't people-dependent? What if the product sold itself?] | [Self-serve funnel, PLG motion, zero salespeople needed] |
Step 4: The 10x Playbook
For the 10x target, identify 3 fundamentally different approaches that would be required. These should NOT be "do more of what we're doing" — they should be qualitatively different strategies.
For each approach:
- The strategy — what's the fundamentally different move?
- Why it's invisible at 1x — why wouldn't you think of this when pursuing the incremental goal?
- What it requires — what capability, investment, or paradigm shift is needed?
- Feasibility signal — has anyone done something like this? What's the proof point?
Step 5: The 2x Insight
Here's the real value: after thinking about 10x, what becomes obvious about achieving 2x?
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.

add-a-zero is a skill published in the GitHub repository sohaibt/founder-mode (3 stars, last pushed 4mo ago), licensed MIT. It adds 61 tokens to every session and 1,036 once invoked, about $0.0003 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 2026-08-31.
