Peter Yang
Overview
Peter Yang is a prominent creator, curator, and commentator in the AI product management and applied AI builder ecosystem. In the newsletter corpus, he appears most often as a source of practical workflows for using coding agents, AI skills, and eval-driven product development. He is especially notable for surfacing hands-on resources—such as the ai-evals-course repository shared in August 2026—and for translating emerging tooling into usable operating patterns for builders.For AI Product Managers, Yang matters because he sits at the intersection of content, workflow design, and practical agent adoption. His posts and interviews consistently focus less on abstract AI hype and more on concrete implementation details: how people use Codex, Claude Code, and related tools in real work; how teams should scope production agents; and how to turn failures into evals, workflows, and product improvements. He also appears as a maker himself through projects like /human-review, reinforcing his role as both educator and practitioner.
Key Developments
- 2026-08-06 — Peter Yang announced /human-review, a free open-source AI skill under the GitHub account petergyang. The tool opens HTML and Markdown files in a visual editor and keeps the review loop local, enabling direct edits, comments, and AI-assisted revision.
- 2026-08-08 — He shared improvements to /human-review, noting 500+ GitHub stars and new features such as Markdown-style lists, links via Command-K, drag-and-drop images, and multi-page review/editing.
- 2026-08-09 — Yang said major blockers to great AI agents include excessive context, inadequate tools, and overly broad use cases, previewing ideas later tied to a Linear-focused production-agent discussion.
- 2026-08-10 — He was associated with coverage of Linear Agent running an LLM in a tool-calling loop with task-specific skills and context from Slack, Linear, and codebases to convert conversations into issues and pull requests.
- 2026-08-11 — Yang recapped five takeaways from Nan Yu and Jacob Shumway at Linear for building production agents: map the real workflow, equip agents to retrieve context, start with one frequent job, use the strongest model first, and convert failures into evals or product tasks.
- 2026-08-13 — He reported that /human-review had reached 717 GitHub stars, positioning it as a Google-Doc-like editing workflow for HTML and Markdown and inviting users to try it.
- 2026-08-16 — Yang announced an upcoming episode with Riley Brown on how Brown uses Codex to run a large-scale content business, including thumbnail and research workflows.
- 2026-08-17 — In that Riley Brown discussion, Yang highlighted advanced Codex skills for researching YouTube videos, generating graphics, drafting outlines, and creating thumbnail variations using tools like Paper, Remotion, and transcript APIs.
- 2026-08-24 — He shared that Char, his assistant from Oceans, uses Claude Code and Codex for podcast post-production, show notes, and clips by adapting Yang’s AI skills to production workflows.
- 2026-08-25 — Yang shared the GitHub repository for ai-evals-course, describing it as a source of free AI eval skills from Shreya and Hamel that can run in Claude Code or Codex.
Relevance to AI PMs
1. A practical source of agent design patterns Yang consistently highlights implementation details that AI PMs can borrow immediately: narrow the initial workflow, reduce context overload, ensure tool access, and instrument failures as evals. These are directly useful when scoping the first version of an AI feature or internal agent.2. A curator of usable AI workflows and skills
His content surfaces concrete assets—not just ideas—including repositories, prompt/skill patterns, and workflow examples for Codex, Claude Code, and eval tooling. PMs can use these examples to speed up prototyping, benchmark team practices, or identify what “good” looks like in production.
3. A bridge between creator workflows and product workflows
Yang’s examples often show how AI tools are actually used in the wild for content ops, editing, research, and execution. For PMs, this is useful because many successful AI products emerge from repeated real-world workflows before they become generalized product features.

“▶️ How I Run My 1.5M+ Follower Content Business With Codex | Riley Brown Peter Yang Riley Brown uses Codex skills to research YouTube videos, generate Remotion graphics and Excalidraw diagrams, draft Notion content outlines, and build Paper-based YouTube thumbnail variations for his 1.5M+ follower AI-content business.”
#3 ▶️ How I Run My 1.5M+ Follower Content Business With Codex | Riley Brown Peter Yang Riley Brown uses Codex skills to research YouTube videos, generate Remotion graphics and Excalidraw diagrams, draft Notion content outlines, and build Paper-based YouTube thumbnail variations for his 1.5M+ follower AI-content business. His YouTube researcher skill uses the Supadata API to pull a full transcript from a YouTube video in about one second; Codex sub-agents can scrape an entire channel in about 30 seconds. He chains an “internet image puller” skill using SerpAPI and Google Images with a Remotion best-practices skill: the agent pulls relevant logos from a video transcript, creates branded graphics, and exports them as overlays for edited video. For thumbnails, Codex scrapes high-performing thumbnails—including Alex Hormozi and Dan Martell examples—into Paper, then Riley Brown uses Paper’s built-in AI image generation to replace the original subject with his own image and iterates on details such as face smoothing, outline glow, text, and colors.

“Peter Yang recapped five takeaways from @thenanyu and @delashum at Linear for building production agents end to end: map the real workflow, equip agents to retrieve context, start with one frequent job, use the strongest model until the workflow works, and turn real failures into evals or product tasks.”
Peter Yang recapped five takeaways from @thenanyu and @delashum at Linear for building production agents end to end: map the real workflow, equip agents to retrieve context, start with one frequent job, use the strongest model until the workflow works, and turn real failures into evals or product tasks. Linear’s first production workflow turned sales notes and Slack discussions into issues; the team launched it quietly and used observed behavior to guide subsequent workflows. Linear also created two feedback loops for poor agent behavior and missing-tool gaps.
