# bojieli/ai-agent-book > Open book on AI agent design principles and engineering practice: 10 chapters, PDF/EPUB in 15 languages, and 109 companion experiments with Python code. - Magnitude: 3.6 out of 10 — Steady - Stars: 55,939 total · +105 stars measured 2026-10-26, 00:14–10:49 UTC, ≈ 208 by evening - Star trust: star growth looks organic - Category: Learning & lists · Language: Python · License: Apache-2.0 · Created: 2025-09-09 · Last push: 2026-10-08 - GitHub: https://github.com/bojieli/ai-agent-book · Page: https://gitnova.dev/en/r/bojieli/ai-agent-book ## Useful for - Study AI agent theory chapter by chapter around Agent = LLM + context + tools - Run companion experiments from chapter1–chapter10 via uv sync --extra chN - Build your own PDF/EPUB from book/ sources using pandoc and xelatex ## Why it’s here - Star-counter measurements on 2026-10-26 (UTC), 00:14–10:49: 55834 → 55939 stars (+105). This is the change over that interval. - Estimated end-of-day forecast: about +208 stars, using observed gains and the previous day. - About 38 forks a day — people are taking the code. ## Star trust Star growth looks organic. Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer. ## Numbers - Forks: 6,416 - Issues and pull requests: 1,177 - Watchers: 209 - Average over the last week: 160 per day - Usual pace: 189 per day - Latest release: latest (2026-07-21) ## Stars per day, last 30 days (oldest → newest, today is partial) 2026-10-04 … 2026-11-02: 156, 117, 127, 225, 225, 211, 165, 194, 197, 317, 209, 193, 134, 117, 149, 167, 172, 200, 161, 98, 121, 160, 39, None, None, None, None, None, None, None ## Magnitude by day, last 14 days 10-13 4.2, 10-14 4.4, 10-15 4.0, 10-16 3.9, 10-17 3.3, 10-18 3.0, 10-19 3.7, 10-20 3.7, 10-21 3.5, 10-22 3.9, 10-23 3.4, 10-24 3.0, 10-25 3.3, 10-26 3.6 --- Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score. Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast. Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
