Score: 73/100 | Verdict: SOLID
Source: Github Trending
[readme] Anthropic released an interactive Prompt Engineering Tutorial (9 chapters + appendix) designed to teach step-by-step prompt construction and troubleshooting for Claude, with exercises and an answer key. The repo is surging in attention (28,279 stars) and is implemented primarily as Jupyter Notebooks. Early GitHub issues show practical breakages (missing module imports, missing f-string interpolation, typos), signaling demand for a more robust, “it just works” learning/runtime environment. This creates a near-term opportunity for tooling that operationalizes prompt-engineering education into testable, versioned, CI-validated prompt assets for teams (not just learners).
Key Facts:
- [readme] The course goal is to teach “optimal prompts within Claude,” including structure, failure modes, strengths/weaknesses, and building prompts from scratch for common use cases.
- [readme] The tutorial is organized into 9 chapters with exercises plus an appendix covering chaining prompts, tool use, and search & retrieval.
- [readme] Each lesson includes an “Example Playground” area and there is an answer key hosted on Google Sheets.
- [readme] The tutorial uses Claude 3 Haiku (smallest/fastest/cheapest) and references Claude 3 Sonnet and Opus as more intelligent alternatives.
- [readme] Anthropic also provides a Google Sheets version via the Claude for Sheets extension and recommends it as more user friendly.

#2 - Vietnam bans unskippable ads
SOLID | 72/100 | Hacker News
Vietnam issued Decree No. 342 amending its Advertising Law, effective Feb 15, 2026, introducing strict UX requirements for online ads. Video/animated ads must become skippable within 5 seconds, while static ads must be immediately cancellable, and “one-interaction” ad closing is required. The decree also bans misleading close symbols and mandates clear reporting/controls so users can report violations and opt out of inappropriate ads. This creates a near-term compliance scramble for ad networks, publishers, and app/game studios operating in Vietnam—opening a product wedge for “VN ad-compliance SDK + audit tooling” and scam-ad detection workflows.
Key Facts:
- Vietnam announced Decree No. 342 with provisions updating the national Advertising Law.
- The decree is due to take effect on February 15, 2026.
- Video and animated ads must allow skipping after no more than 5 seconds (hard cap).
#3 - LMArena is a cancer on AI
SOLID | 70/100 | Hacker News
Surge AI argues LMArena’s open, volunteer-driven voting system systematically rewards “aesthetics of competence” (verbosity, formatting, emojis, sycophancy) over factual correctness, making the leaderboard easy to game. The authors claim they reviewed 500 LMArena votes and disagreed with 52% (strongly with 39%), citing examples where objectively wrong answers won due to confidence/packaging. HN commenters echo Goodhart’s Law (“any metric that can be targeted can be gamed”) and note perceived misalignment between linguistic polish and true capability (e.g., GPT-4.5 not topping Arena). This creates a near-term product gap for “evaluation you can trust” (expert-anchored, audit-able, domain-specific, and resistant to presentation hacks), especially for enterprises and regulated domains.
Key Facts:
- LMArena’s mechanism is pairwise response voting by Internet users, which the article claims leads to shallow evaluation (skimming, little/no fact-checking).
- The article asserts models can improve Arena rank by being more verbose, using aggressive formatting, and “vibing” (including emojis), regardless of correctness.
- The article claims Meta tuned a version of “Maverick” to dominate the leaderboard and that it responded to simple prompts (e.g., “what time is it?”) with attention-grabbing but non-answer behavior.
📈 Market Pulse
Strong community pull is indicated by 28,279 GitHub stars for an educational repo. The issue stream shows active user engagement focused on correctness and usability (missing dependencies, interpolation bugs), suggesting learners and practitioners are trying to run the material rather than passively read it.
Community sentiment is broadly supportive of skip/close requirements for consumer protection, especially for kids’ mobile games and scam-heavy ad ecosystems, though at least one commenter flags potential unintended consequences of regulation. Multiple comments highlight deceptive UX patterns (invisible/late close buttons) and long interstitial durations as a persistent pain point, implying latent demand for enforcement and compliance tooling.
