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 | $0.00118 | $0.01620 |
| Opus 5 | $0.00059 | $0.00810 |
| Sonnet 5 | $0.00024 | $0.00324 |
| Haiku 4.5 | $0.00012 | $0.00162 |
Grade A, and why
market-gate 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 12d 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
THE GATE — if the ceiling is under ฿1B, we don't enter. No exceptions, no sentiment.
Building a ฿10M business and building a ฿1B business take roughly the same years, the same nights, and the same operator. The only difference is which market you walked into on day one. This skill is where that decision is made, with arithmetic, before anyone falls in love.
The gate tests the ceiling, not the forecast. The question is never "will we make ฿1B?" — it is "could this market pay us ฿1B/yr if we won it?" If the honest answer is no, we do not enter, however charming the idea is.
The rule
CEILING = reachable buyers × realistic annual price × attainable share
GATE: CEILING ≥ ฿1,000,000,000 / year → may proceed
CEILING < ฿1,000,000,000 / year → killed, logged, next candidate
No year limit on reaching it — a slow ฿1B market beats a fast ฿50M one. But among candidates that clear the gate, speed wins every tie: rank by time-to-first-baht, then by time-to-฿1B.
BANNED (sizing theatre)
- Top-down TAM. "The global market is $47B, we only need 1%" is the single most reliable predictor of failure ever written into a deck. 1% of a market you cannot reach is 0%.
- Uncited inputs. Every number in the arithmetic needs a source or a stated, labelled assumption. "About 50,000 shops, probably" is not an input.
- Counting people you cannot reach or bill. The buyer must be reachable through a channel that exists and payable in a currency you can accept.
- Retrofitting the numbers to save a favourite idea. If you find yourself widening the definition of the buyer to clear the gate, the idea already failed — you're negotiating with a spreadsheet.
- Confusing revenue with profit ceiling. Check gross margin too: ฿1B of revenue at 8% margin is a logistics company with a founder's salary.
- Ignoring the incumbent's grip. Attainable share is not 30% when one player owns 80% and every buyer is on a 3-year contract.
- Gating on feelings. "It could be huge" is not a number. Run the tool.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

market-gate is a skill published in the GitHub repository ikarisz/Bobby-Need-To-Billionaire (2 stars, last pushed 17d ago), licensed MIT. It adds 118 tokens to every session and 1,620 once invoked, about $0.0006 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.
