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 | $0.00000 | $0.01864 |
| Opus 5 | $0.00000 | $0.00932 |
| Sonnet 5 | $0.00000 | $0.00373 |
| Haiku 4.5 | $0.00000 | $0.00186 |
Grade A, and why
growth-engine 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 2d 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 — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Growth Engine
The developer-tools growth specialist who knows what makes repos go viral, what gets you banned on Reddit, and how to turn 100 GitHub stars into 10,000 without ever sounding like marketing.

What It Does
The Growth Engine is not a generic marketing agent. It is a developer-tools growth specialist who understands that developers have hype antibodies. It knows that "revolutionary" gets you downvoted on Hacker News, that copy-pasting content across platforms is malpractice, and that vanity metrics (impressions, followers) mean nothing while pipeline metrics (installs, activations, retained users) mean everything.
It operates across every growth channel with platform-native playbooks: Hacker News (Show HN anatomy, response strategy, timing), Reddit (karma-building before self-promotion, comment voice rules, subreddit-specific tactics), Twitter/X (build-in-public threads, demo videos, engagement ratios), Product Hunt (launch day choreography, hunter selection, post-mortem), LinkedIn, Dev.to/Hashnode, and GitHub itself as a growth channel (README optimization, issue templates, awesome-list inclusion).
Beyond channel tactics, it provides strategic growth frameworks: content calendar creation with SEO-informed topic selection, open source viral loop analysis (discovery, README conversion, time-to-value, aha moment, share trigger), community building infrastructure, email drip campaign design, competitive positioning, and analytics/attribution setup. Every output ends with a specific decision and a measurement plan -- intelligence, not information.
When to Use It
- Launch planning: When you are preparing to launch on Hacker News, Product Hunt, Reddit, or any developer community and need a platform-specific playbook.
- Open source growth strategy: When your GitHub repo has great code but nobody finds it, and you need a systematic plan to grow discoverability and adoption.
- Content marketing: When you need a quarter's content calendar with topic research, keyword targets, distribution channels, and publishing cadence.
- Competitive positioning: When competitors are shipping similar features and you need to find your differentiated angle backed by evidence.
- Post-launch analysis: After any launch (successful or not), when you need a structured post-mortem to learn what worked and what did 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.
