4. Quality-bar self-checklist · 条目自查

GitHub stars at submission time:

• NoFxAiOS/nofx: 12,542 stars; last pushed 2026-07-10; AGPL-3.0.

• Lumiwealth/lumibot: 1,804 stars; last pushed 2026-07-10; GPL-3.0.

• chengzuopeng/stock-sdk: 1,671 stars; last pushed 2026-07-07; ISC.

• HammerGPT/Hyper-Alpha-Arena: 1,096 stars; last pushed 2026-05-13; Apache-2.0.

• Open source — or has a public technical artifact
  (paper, architecture doc, reproducible demo).

• Demonstrably LLM-driven — LLM reasoning is a primary
  decision component (not feature extractor / post-hoc explainer).

• Active in last 12 months — or canonical / foundational reference.

• Clear scope + minimal documentation.

• Distinct contribution — not duplicative of existing entries.

• Public credibility signal — normally >=100 GitHub stars
  for repo entries, or a documented maintainer-level exception.

If any box is unchecked, briefly justify the waiver:

N/A. All four entries exceed the maintainer's 300-star threshold and expose a distinct open agentic or MCP surface.

5. Bilingual symmetric-edit · 中英文同步

• I edited both README.md and README.zh-CN.md in this PR.
• I opened a tracked translation issue with 7-day SLA.

6. Awesome-lint advisory check · awesome-lint 辅助检查

• I ran npx --yes awesome-lint README.md, or this PR does not change README structure.
• I ran npx --yes awesome-lint README.zh-CN.md, or this PR does not change README.zh-CN.md structure.
• Notes / ignored findings:

Both awesome-lint commands passed. The four new GitHub URLs returned HTTP 200, and bilingual headings / anchors remain structurally symmetric.

7. Curation notes (optional) · 补充说明（可选）

These entries were selected from the 2026-W28 weekly scan plus a follow-up GitHub topic search using a stricter 300-star threshold and an explicit alpha / differentiation review.

• NoFxAiOS/nofx is listed under single-agent traders because each LLM trader runs its own decision loop; the real-money / competition section receives only a cross-link to its multi-model leaderboard.
• HammerGPT/Hyper-Alpha-Arena expands the strategy-coding cluster from LLM-written strategies into factor mining, IC / ICIR validation, decay analysis, backtesting, and trade attribution.
• Lumiwealth/lumibot now ships a code-level agent runtime with research, debate, memory, deterministic execution gates, and canonical multi-agent demos. Its upstream README shows an MIT badge, while the repository LICENSE and GitHub metadata are GPL-3.0; this PR uses the LICENSE file as authoritative.
• chengzuopeng/stock-sdk adds a zero-dependency TypeScript MCP/data surface across A-share, Hong Kong, US-equity, and fund markets.
