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 | $0.00067 | $0.02356 |
| Opus 5 | $0.00034 | $0.01178 |
| Sonnet 5 | $0.00013 | $0.00471 |
| Haiku 4.5 | $0.00007 | $0.00236 |
Grade A, and why
startup-marketing-brain 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 11d 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.

Startup Marketing Brain
Leading words: bootstrapping, engineering as marketing, agentic growth ops, distribution, validation stack, F5bot, Founding 50, content loop, platform sniping, runtime eligibility.
A comprehensive playbook for bootstrapped founders, indie hackers, and solo builders who need to market, distribute, and grow digital products without venture capital or large teams.
Core mental models
- Bootstrapping is an advantage. Lower costs, full ownership, no VC bullshit. The constraint forces clarity.
- Distribution is the hardest problem. Most founders fail because they cannot find customers — not because the product is bad. Marketing first, product second.
- Everything is a funnel. Optimize each stage from impression to conversion. Free users do not validate a business — charge from day one.
The other 7 mental models from the previous version (solve your own problem, simplicity wins, creators are the new distribution, automate everything, build in public, validate before building, AI as multiplier) live in references/ideation_playbook.md and references/growth_operations.md.
Phase 1 — Validate
- [ ] Idea comes from a personal problem or domain expertise.
- [ ] Built a prototype of the "magic moment" (Cursor, 1-2 hours) + recorded
a 30-second demo.
- [ ] Launched an Early Adopter Program (Founding 50) — 50% discount on an
annual prepaid plan to fund development with cash upfront.
- [ ] Collected waitlist emails.
- [ ] Pre-sold to at least 3 customers (manual-first).
Pull references/ideation_playbook.md for the full validation stack.
🛑 Checkpoint: State the validation signal in one sentence (e.g. "100+ waitlist signups + 3 pre-sales"). Do not proceed to Distribute until demand is proven.
Phase 2 — Distribute
- [ ] Free tools (Engineering as Marketing) — filter Ahrefs for KD < 10,
Volume > 1000; build dozens in Cursor; host on your domain with CTAs.
- [ ] Runtime eligibility check (CRITICAL — see note below) before posting
to any community platform.
- [ ] Reddit/FB: mapped 5 communities, lurked 2 weeks, started in comments,
provided extreme value first.
- [ ] Twitter/X: building in public daily using the Content Loop (Entertain
→ Educate → Inspire → Convince).
- [ ] TikTok: Hook-Problem-Solution framework; pin organic winners; scale
paid behind proven organic.
- [ ] F5bot alerts set up for pain-point keywords.
What ships with it
7 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.

startup-marketing-brain is a skill published in the GitHub repository afaraha8403/balakit (1 stars, last pushed today), licensed MIT. It adds 67 tokens to every session and 2,356 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.
