### 1. Harrison Chase

- **One-liner**: LangChain creator. Drove agent framework from "ReAct paper concept" to "engineering standard"; now publicly arguing the framework abstraction itself decays as model capability grows.
- **核心身份**: LangChain CEO; previously Robust Intelligence
- **代表作品**: LangChain (90k+ stars), LangGraph, LangSmith
- **核心思想关键词**: framework decay; graphs > chains; observability-first; eval-driven dev; "ship in a weekend, replace in a weekend"
- **最近 12 个月动态**: pivoted public messaging from "use LangChain for everything" toward "use LangGraph as a thin layer; expect to replace it in 12 months". LangSmith eval focus increased.
- **争议 / 批评**: LangChain accused of pre-mature abstraction by 2023-24 critics; LangGraph rewrite was the response; some critics now say LangGraph repeats the same mistake.

  - [Primary] LangChain Interrupt 2025 keynote — "Frameworks are temporary" (URL placeholder)
  - [Primary] Latent Space pod with Swyx 2025-Q1 (URL placeholder)
  - [Secondary] HN thread "Why I dropped LangChain" 2024-09 (URL placeholder)
  - [Reference] Anthropic agent docs cite LangGraph (URL placeholder)
- **sub_skill_candidate**: true (60min keynote + 思想体系成型 + 影响力前 5)
- **可信度**: high

### 2. Andrej Karpathy

- **One-liner**: Independent thinker on LLM-as-agent. Frames everything through the "bitter lesson" — anything that lets you encode less heuristic into the system will win.
- **核心身份**: Independent (formerly OpenAI / Tesla); long-form video essayist
- **代表作品**: NN-zero-to-hero series, agent commentary on X, several long talks
- **核心思想关键词**: capability eats abstraction; LLM as new computer; agentic dev workflow; UNIX-style composability
- **最近 12 个月动态**: increased focus on LLM-as-agent commentary and tooling-mostly-self-built workflow demos; the "agentic coding" narrative is influential.
- **争议**: not really controversial, but his views on framework / hand-built tradeoff are sometimes read as anti-framework dogma.
- **来源**:
  - [Primary] X threads on agent observations, multiple 2024-2025
  - [Primary] YouTube long videos (Build GPT, etc.) 2023-2024
  - [Primary] LMSYS / Stanford talks 2024
  - [Secondary] Multiple podcasts referencing his framing
  - [Reference] Cited in 4+ papers on agent design
- **sub_skill_candidate**: true (multiple 1h+ talks + 自成一派思想体系)
- **可信度**: high

### 3. Hamel Husain

- **One-liner**: Practitioner-blogger focused on LLM eval. The most-cited engineer for "build the eval before the agent."
- **核心身份**: Independent consultant; previously GitHub / Airbnb
- **代表作品**: blog series on LLM eval, courses on practical LLM eng
- **核心思想关键词**: eval > model architecture; production reality vs demo; LLM-as-judge with human validation; trace-driven debugging
- **最近 12 个月动态**: continued advocacy for eval-as-data; 与 Eugene Yan 合作出 eval workshop
- **来源**:
  - [Primary] hamel.dev eval blog series 2024-2025
  - [Primary] Latent Space podcast appearance
  - [Secondary] referenced by Anthropic team in agent eval discussions
  - [Reference] cited in Inspect AI documentation
- **sub_skill_candidate**: true (long blog corpus + 思想体系自洽)
- **可信度**: high

### 4. Simon Willison

- **One-liner**: Long-time independent developer-writer. His 800+ blog posts are the most-thorough living documentation of pragmatic LLM tooling.
- **核心身份**: Independent (Datasette creator); prolific blogger
- **代表作品**: Datasette, llm CLI, blog (simonwillison.net)
- **核心思想关键词**: framework as scaffold; tools as primitive; everyday LLM workflows; eval-driven extension building
- **最近 12 个月动态**: shifted from generic LLM tooling to specific agent patterns; commentary on Anthropic Computer Use, MCP integration.
- **来源**:
  - [Primary] simonwillison.net (multiple posts/week)
  - [Primary] Mastodon and X threads
  - [Primary] PyCon 2024 talk
  - [Secondary] HN sticky threads referencing his analysis
  - [Reference] LLM CLI cited in framework docs
  - [Reference] cited in Anthropic posts
- **sub_skill_candidate**: true (system-grade thinking, 自创术语 e.g. "tools-shaped problem")
- **可信度**: high

### 5. Mike Knoop

- **One-liner**: ARC Prize co-founder. Frames the field around the question "what is the agent doing that the model alone can't?"
- **核心身份**: Adept founder; ARC Prize co-founder
- **代表作品**: ARC-AGI benchmark + prize; Adept agent products
- **核心思想关键词**: capability scaffolding; abstraction failure points; "frameworks fail when the model exceeds them"
- **最近 12 个月动态**: ARC Prize 2024 results commentary; "what made o1 special" essays
- **来源**:
  - [Primary] ARC Prize keynote 2024
  - [Primary] Cognitive Revolution podcast 2024
  - [Secondary] coverage in NYT / FT
- **sub_skill_candidate**: false (思想 still forming, fewer long-form anchors)
- **可信度**: medium

## Phase 2 提炼提示

**反复出现 ≥ 3 figures 都谈到的关键词**:
- "Framework as scaffold, not foundation" (figures: Chase, Karpathy, Willison, Knoop)
- "Eval > model architecture" (figures: Husain, Chase, Husain-Yan-collab)
- "Production reality vs demo glamour" (figures: Husain, Willison, Chase)
- "Capability eats abstraction" (figures: Knoop, Chase, Karpathy)

**显著分歧 / 流派分裂**:
- "Thin frameworks" 派 (Chase post-pivot, Willison, ai-sdk crew) vs "Thick orchestration" 派 (CrewAI, AutoGen) — Track 01 sees Chase straddling but post-2025 Q1 he's clearly thin
- "Pure agent" (open-ended planning) vs "Workflow with LLM steps" (emerging consensus on the latter)

**冷僻信号**: 5 figures is below 13 target. Minimal-viable scope; not a real cold-industry indicator. ✅ industry not cold.
