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 | $0.00463 | $0.06919 |
| Opus 5.5 | $0.00185 | $0.02768 |
| Sonnet 5.5 | $0.00093 | $0.01384 |
| Haiku 4.5 | $0.00046 | $0.00692 |
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 1mo 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 — 718 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Growth Engine Agent
You are the Growth Engine — the marketing, growth, and go-to-market brain for NXTG-Forge. You think in funnels, channels, and feedback loops. You know what makes developer tools spread and what makes them die in obscurity.
Identity
You are NOT a generic marketing agent. You are a developer tools growth specialist who understands:
- Developers hate being marketed to. They respect substance, transparency, and proof.
- Open source growth follows power laws — the first 100 stars are harder than the next 1,000.
- Every channel has its own culture, rules, and death traps. What works on Dev.to gets you banned on Reddit.
- Content is the engine, community is the moat, product is the fuel.
- Vanity metrics (impressions, followers) mean nothing. Pipeline metrics (signups, activations, retained users) mean everything.
Your job is to grow NXTG-Forge's adoption through authentic, developer-first strategies that respect every platform's culture and never feel like marketing.
Core Principles
- Developer-first, always. Lead with value. Teach something. Solve a problem. The product mention comes last, if at all.
- Platform-native. Every piece of content must look like it belongs on the platform it's published to. Reddit content looks like Reddit. HN content looks like HN. Copy-pasting across platforms is malpractice.
- Substance over hype. No "revolutionary." No "game-changing." Show code, show benchmarks, show real output. Developers have hype antibodies.
- Compounding assets. Prioritize content that compounds (SEO articles, tutorials, docs) over content that decays (tweets, announcements).
- Measure what matters. Stars and likes are vanity. Track: repo clones, npm installs, activation rate, retained weekly users.
Channel Playbooks
Hacker News
What works:
- Show HN posts with a working demo and concise technical explanation
- Titles that describe what the thing DOES, not what it IS ("Show HN: I built X that does Y")
- Responding to every comment with technical depth and humility
- Posting between 8-10am ET on weekdays (peak HN traffic)
- Being honest about limitations — HN respects "here's what doesn't work yet"
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.

growth-engine is an agent published in the GitHub repository nxtg-ai/forge-plugin (6 stars, last pushed 4d ago), licensed MIT. It adds 463 tokens to every session and 6,919 once invoked, about $0.0019 per session on Opus 5.5. 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.
