Reusable behavior modules or instructions for guiding AI agents. The newsletter mentions skills as one of the steering mechanisms for Claude Code and other agents.
Key Highlights
- Skills are reusable instruction or behavior modules that help AI agents perform tasks more consistently.
- They are emerging both as internal steering controls for agents like Claude Code and as installable, agent-agnostic capability packages.
- For AI PMs, skills are a practical way to improve reliability, encode best practices, and expose product functionality to agents.
- Newsletter mentions connect skills with APIs, MCP, CLIs, and open standards for more portable agent ecosystems.
- Recent discussion suggests skills may become a foundational abstraction for controlling and extending agentic products.
Skills
Overview
Skills are reusable behavior modules, packaged instructions, or preconfigured context that guide how an AI agent performs specific tasks. In the newsletter, the term appears in two closely related ways: as a steering mechanism inside agentic systems such as Claude Code, and as an open, installable ecosystem of agent capabilities popularized by Guillermo Rauch’s `skills` project. In both cases, the core idea is the same: instead of relying on a model to infer the right behavior from scratch every time, product teams can provide repeatable task-specific guidance.For AI Product Managers, skills matter because they offer a practical layer between raw model capability and reliable product behavior. They can improve consistency, reduce prompt drift, encode best practices for recurring workflows, and make agents easier to extend through APIs, CLIs, MCP-compatible tools, or task-specific instructions. As agents become a primary interface, skills are emerging as one of the key abstractions for making them controllable, composable, and potentially portable across agent harnesses.
Key Developments
- 2026-01-18: Guillermo Rauch introduced 𝚜𝚔𝚒𝚕𝚕𝚜, described as an open, agent-agnostic ecosystem of AI capabilities installable via an npm-like CLI.
- 2026-01-31: Dharmesh Shah recommended defining custom skills as preconfigured instructions and context for frequent tasks, especially to reduce reliability issues in coding assistants.
- 2026-02-22: Peter Yang argued that in the agent era, products should empower agents to complete tasks via APIs, skills, and MCPs so that user time spent in the product trends toward zero.
- 2026-03-06: Guillermo Rauch launched a Rust-based Google Workspace CLI installable via npm or Skills (`skills.sh`) and predicted 2026 would be the year of skills and CLIs.
- 2026-05-03: Harrison Chase noted that memory and integrations remain tightly coupled to the agent harness, while `agents.md` and skills are among the few signs of an emerging open standard.
- 2026-06-19: Claude Code announced new steering controls including CLAUDE.md, alongside skills, hooks, rules, and subagents as mechanisms for guiding agent behavior.
Relevance to AI PMs
- Design more reliable agent workflows: Skills let PMs package recurring instructions, guardrails, and context for common tasks, which can reduce inconsistent outputs and lower operational surprises.
- Create extensible product surfaces for agents: If your product exposes capabilities through APIs, CLIs, MCP servers, or installable skills, agents can use your product more directly without requiring a human to navigate every UI step.
- Plan for portability and ecosystem fit: As teams evaluate agent frameworks, skills may become a useful abstraction for separating reusable task logic from a specific harness, making it easier to support multiple agent environments.

- Claude Code / Claude / CLAUDE.md: Claude Code frames skills as one of several steering mechanisms for shaping agent behavior, alongside project-level instruction files.
- Hooks, Rules, Subagents: These are adjacent control primitives; skills typically package reusable behavior, while hooks trigger actions, rules constrain conduct, and subagents delegate work.
- MCP: Skills are often discussed with MCP as part of the infrastructure for giving agents structured access to tools and product capabilities.
- CLIs / Google Workspace CLI / Vercel / Guillermo Rauch: Rauch’s work connects skills to developer tooling and installable capabilities, suggesting a distribution model similar to package managers.
- agentsmd / claudemd / open-harnesses: These relate to emerging attempts at open conventions for agent instructions, portability, and reduced lock-in to a single harness.
- Harrison Chase, Peter Yang, Dharmesh Shah: Each highlighted a different PM-relevant angle: standards, product access via agents, and reliability through preconfigured task guidance.

From LinkedIn • Deeper Insights AI Tools & Applications Dharmesh Shah’s post highlights a common reliability pitfall with agentic coding assistants like Claude Code: when they reply “you’re absolutely right,” they may overlook errors or violate principles such as DRY (Don’t Repeat Yourself). To mitigate this, he recommends defining custom “skills”—preconfigured instructions and context—for frequent tasks. This approach helps maintain consistency and reduce surprising mistakes, even when leveraging advanced models like Opus 4.5.
