orallexa-marketing-agent 0.19.0

AI marketing agent for OSS founders — auto-generate and distribute project content across X, Reddit, LinkedIn, and more. v0.19.0 adds bandit predict() — JEPA-flavored predictor layer.

Orallexa Marketing Agent

English | 中文

Submit your AI/OSS project once. Get auto-generated, platform-specific marketing content. Distribute everywhere.

An open-source Python SDK + CLI for solo OSS founders who write code well but don't have time (or audience) to do marketing themselves.

Built by Xiaoyu (Alex) Ji — Navy veteran, MS CS @ Yeshiva University, building Orallexa and VibeXForge. Yes, it's named after Orallexa — that's the project that needed it most.

---

🚀 Live in production at vibexforge.com

VibeXForge is the distribution amplifier built on top of this agent. Paste your AI project URL → 17 platform-native posts in 10 seconds. Every draft you see at vibexforge.com is generated by the same code that's public in this repo (the TypeScript port of marketing_agent/content/generator.py lives in vibex/lib/draft-generator.ts).

If you want a hosted UI / HITL editor / per-platform engagement scrape on top of this SDK, try VibeXForge. If you want the SDK alone for your own pipeline, keep reading — pip install orallexa-marketing-agent.

Why this exists

You shipped a great AI/OSS project. 27 days later: 28 stars. Sound familiar?

The problem isn't the product. It's distribution. You're a builder, not a marketer. You have 3 GitHub followers and zero Twitter audience.

This is the tool I wish I had on day one of every OSS project: feed it a project description and it produces ready-to-post content tuned to each platform's voice — with a human-in-the-loop for the things that matter.

---

Quickstart (30 seconds, no API keys)

git clone https://github.com/alex-jb/orallexa-marketing-agent.git
cd orallexa-marketing-agent
make install
make demo      # runs examples/generic_demo.py — no keys needed, all dry-run

You'll see X / Reddit / LinkedIn drafts for a fake project, generated locally via templates.

To enable LLM-quality content, add an Anthropic key to .env. To actually post, add platform keys. Both are optional — the SDK degrades gracefully.

Status — v0.18.6 (PyPI live, full bandit feedback loop running)

408 tests passing · 77% coverage · CI green Python 3.11 / 3.12 · live on PyPI: pip install "orallexa-marketing-agent[mcp]"

Layer	What works today
Generator	HYBRID = Cloudflare Workers AI edge tier (Llama 3.3, ~$0.011/1M tokens) → Anthropic Sonnet 4.6 fallback. Falls through to deterministic templates if both fail (with warning log so silent failure is impossible). Prompt caching cuts cost ~80% on daily cron.
Quality gate	Heuristic + LLM critic (auto-rejects hype words, length overflow, hashtag spam). Hybrid retrieval dedup (60% dense + 40% BM25, +17pp MRR vs dense-alone) — never reposts a paraphrase. 3-layer X 280-char overflow defense (small hook + strict prompt + post-LLM retry/truncate).
Self-evolving stack	Variant bandit (Thompson Beta-conjugate over emoji/question/stat-led; pre-LLM hint selection so 1 LLM call per platform). Reflexion memory (cross-session critic patterns). ICPL preference store (5-shot exemplars from human edits). Voyager auto-skill promotion (top-quartile posts → skills/learned/*.md AND ~/.solo-founder-os/skills/<slug>.md for cross-agent reuse).
Proactive loop	Trends module scans GitHub / HN / Reddit (free, stdlib HTTP only) + VibeX top-of-feed source (your own platform's hot projects via Supabase Management API, $0). trends_to_drafts turns top N into platform-specific drafts. Per-(project, URL) cooldown (default 7d) prevents writing about the same hot story 4 days in a row.
Cost guards	MARKETING_AGENT_DAILY_BUDGET_USD soft cap (reads ~/.marketing-agent/usage.jsonl, prices via cost.PRICES, sums today UTC; skips proactive pass when over). Cross-provider usage logging into a single JSONL the cost-audit-agent reads.
Platforms — auto-publish	X (OAuth 1.0a + Bearer for reads) · Reddit (PRAW) · Bluesky (AT Protocol) · Mastodon (REST) · Threads (Meta Graph API, production April 2026)
Platforms — content-prep only	Dev.to (markdown export) · LinkedIn (API restricted) · 知乎 / 小红书 (manual paste, never auto — see Chinese platform strategy)
Workflow	HITL approval queue (Obsidian-friendly markdown). 6 GitHub Actions: daily.yml (commit-driven + trends drafts), publish.yml (push to approved/), scheduled.yml (hourly publish-due), test.yml, lint.yml, mcp-install-check.yml. Multi-project YAML config (one cron, N projects). PyPI Trusted Publishing via OIDC.
Cross-agent (SFOS interop)	Reflexions, skill promotions, and ICPL pairs are mirrored to ~/.orallexa-marketing-agent/*.jsonl and ~/.solo-founder-os/skills/ so solo-founder-os v0.19+ tools (sfos-evolver, sfos-retro, sfos-eval) see marketing-agent's data. Bandit + autopsy promoted to SFOS core for the rest of the stack.
Automation	Local launchd jobs: daily 06:30 EDT auto-pulls X engagement → updates bandit posterior. Sunday 09:00 runs sfos-retro cross-agent digest. PH-day reminder + trend-perf retro launchd plists ship as scripts.
Integrations	MCP server (marketing-agent-mcp for Claude Code / Desktop / Cursor / Zed) · Claude Skill (skills/marketing-voice/) · A2A agent card (agent_card.json) · VibeXForge event push · DSPy signatures framework
Distribution	PyPI (pip install orallexa-marketing-agent[mcp]) · Dockerfile + docker-compose · CI matrix Python 3.11/3.12 · pytest-cov 70% floor · Codecov

CLI (17 subcommands): generate · post · history · cost · queue · plan · schedule · ui · trends · trends-to-drafts · autopsy · skills · image · bandit · best-time · replies · engage

Roadmap (recent + upcoming):

• v0.10-0.12 — Streamlit UI · scheduled posting · ICPL · LiteLLM ensemble critic · Bluesky firehose · Cloudflare edge inference · Voyager skill promotion · A/B variants report · autopsy
• v0.13-0.14 — solo-founder-os AnthropicClient migration · cross-provider usage logging
• v0.15-0.16 — Trends module (GitHub/HN/Reddit) · Threads (Meta) auto-publish

Chinese platform strategy — 2026 reality

Per Q2 2026 anti-bot research, the agent deliberately does not auto-publish to 小红书 (Xiaohongshu) or 知乎 (Zhihu). Here's why and what we do instead.

Why no auto-post:

• 小红书's 阿瑞斯 risk system uses TLS fingerprinting + behavioral telemetry. Playwright + stealth defeats client-side fingerprints but not TLS or behavioral models. Detection is behavioral.
• New 小红书 accounts need 2-4 weeks of 养号 before they can publish without shadow-bans. Jan 2026 sweep: 37 matrix accounts banned in one operator.
• 小红书 requires self-disclosure of AI-assisted content (高级选项 → 内容类型声明). Failing to disclose triggers limit/ban.
• 知乎 has no public publishing API since 2020. Multi-account automation gets caught fast.
• Anthropic Computer Use works functionally but adds no detection advantage over Playwright (same browser surface) and costs ~$0.30-1/post in screenshot tokens.
• Official 小红书 开放平台 is whitelist-only (蒲公英 / 聚光 / 千帆 — brands, not indie devs).

What the agent DOES do for these platforms:

1. Generates platform-tuned content prep via marketing_agent.platforms.zhihu.dry_run_preview() and xiaohongshu.dry_run_preview() — formatted body + AI-disclosure reminder + algorithm-friendly hooks + length classifier (短答/中等/长答 for 知乎, 配图建议 for 小红书).
2. Reminds you of every 2026 platform rule before you paste manually.
3. Routes you to the right place: 知乎 to a target question (回答 ≫ 文章 for SEO), 小红书 to creator.xiaohongshu.com with the AI checkbox checked.

The 80/20 path for an indie OSS founder in 2026:

• One real warmed account per platform. Manual publish, 2-3x/week.
• 知乎 = highest leverage. Long-form 回答 with code blocks ranks on Baidu for years.
• Skip 微信视频号 (April 2026 banned all third-party automated publishing).
• For video content, use Bilibili (official open platform supports uploads with a real dev account).
• Reserve automation for read-only: trend scraping, comment monitoring, competitor 笔记 analysis.

Bottom line: Automate the writing pipeline, not the publish button. The agent is doing this because the 2026 ROI of automated Chinese-platform posting is negative once account-burn is factored.

Design principles

1. Tri-mode operation — works with no keys (template fallback), with Claude key (LLM generation), with platform keys (real posting). Never crash for missing keys.
2. Pydantic everywhere — no untyped dicts crossing module boundaries.
3. Adapters are protocols — same interface for every platform, easy to extend.
4. Reasonable defaults — make demo works offline, no setup.
5. No secrets in code — os.getenv exclusively, .env.example as template.

Automation — HITL pipeline (GitHub Actions)

Two workflows form a draft → review → publish loop. The agent never posts to social media without your approval, but everything else is automatic.

        ┌─────────────────────┐
        │ daily.yml @14:00 UTC│  scrapes GitHub commits → drafts → queue/pending/
        └──────────┬──────────┘  → opens "📥 Daily drafts ready" Issue
                   │
                   ▼
        ┌─────────────────────┐
        │  YOU review         │  on github.com or after `git pull`
        │  • approve  →  git mv pending/X.md approved/X.md
        │  • reject   →  git mv pending/X.md rejected/X.md
        └──────────┬──────────┘
                   ▼
        ┌─────────────────────┐
        │ publish.yml         │  triggered by push to queue/approved/
        └──────────┬──────────┘  → posts to X / Reddit / Bluesky / etc.
                   │             → moves to queue/posted/, commits state back
                   ▼
              real social media

One-time setup

1. Add secrets at https://github.com/<you>/<repo>/settings/secrets/actions:

   • ANTHROPIC_API_KEY (optional — falls back to template mode)
   • X_API_KEY, X_API_KEY_SECRET, X_ACCESS_TOKEN, X_ACCESS_TOKEN_SECRET
   • REDDIT_*, BLUESKY_*, MASTODON_* (any platform you want enabled)

2. Trigger first run manually: Actions → "Daily draft generator (HITL)" → Run workflow.

3. Approve a draft to test publish.yml:

   git pull
   git mv queue/pending/<file>.md queue/approved/<file>.md
   git commit -m "approve: test" && git push
   

Skipping rules

daily_post.py skips when:

• No commits in the lookback window (default 24h)
• All commits are CI-only / docs-only / chore-only

Override with --force (testing only).

Targets

daily.yml defaults to alex-jb/orallexa-ai-trading-agent. Add new repos to REPO_PRESETS in scripts/daily_post.py, or pass --repo via workflow_dispatch.

Future / paid offering — speculative

A managed-SaaS layer on top of marketing-agent (running inside VibeXForge) is fully designed but not yet built. See docs/future/saas-design.md for the architecture, pricing, and the explicit demand-signal threshold that would trigger Phase-1 work.

Today's promise stays the same: the OSS tool here is the whole product, and it always will be free. The SaaS doc exists so an interested founder / investor / collaborator can understand the scaling story without me having to retell it.

The MCP-server side of distribution (Anthropic marketplace + modelcontextprotocol/servers registry) is shipping post-PH 2026-05-04 — see docs/mcp-listing/ for the kit.

🧩 Part of the Solo Founder OS stack

A growing collection of MIT-licensed agents that share solo-founder-os as their base — Source/MetricSample contracts, HITL queue, AnthropicClient, notifiers, scheduler. Each agent is independently useful; together they cover the full solo-founder workflow.

Agent	What it does
solo-founder-os	The shared base lib (Source/MetricSample, AnthropicClient, HITL queue, notifiers, sfos-doctor / sfos-evolver / sfos-eval / sfos-retro / sfos-bus / sfos-inbox)
build-quality-agent	Pre-push diff reviewer + local build runner — catches CI-killing changes before they ship
customer-discovery-agent	Reddit pain-point scraper + Claude clustering for product validation
funnel-analytics-agent	Daily brief + real-time alerts across 9 sources (Vercel, GitHub, Supabase, etc.)
vc-outreach-agent	Investor cold email drafter with HITL queue + SMTP sender
cost-audit-agent	Monthly bill audit across 6 providers with dollar-tagged waste findings
bilingual-content-sync-agent	EN ⇄ ZH i18n diff + Claude translate + HITL apply

Each agent's own row is omitted from its README. Install whichever solve real problems for you.
