Skills as Versioned Infrastructure for AI Agents
The author argues that copying prompts is brittle and that teams should formalize reusable, versioned "skills" with explicit output contracts and routing signals so AI agents produce consistent, implementable artifacts. Using an order-api project example, the author converts a Gherkin scenario–quality prompt into a skill, demonstrating that the skill reduces implicit decisions, enforces explicit assertions (HTTP status, field names/values), and surfaces assumptions. The piece describes three properties that differentiate skills from prompts—version control, an output contract, and a routing description—and presents a concrete demonstration where the skill produces clearer, more actionable Gherkin scenarios and a failure case. Sources and links include a project repository and a documented Gherkin quality skill. Publication date: 2026-06-29.
Conceptual guidance on formalizing agent skills is useful for engineering teams building agentic workflows, but the article is an individual essay rather than an industry-level technical release or policy change.

Key Takeaways & Evidence Grounding
- The article distinguishes ephemeral prompts from durable, versioned "skills" that include an output contract and routing signal.
- A Gherkin scenario quality evaluation was chosen as a prompt-to-skill conversion candidate in the author's order-api project.
- The author demonstrates that a skill-produced Gherkin scenario surfaces far fewer implicit decisions than a prompt-produced scenario.
- The article defines three properties of skills: version control, explicit output contracts, and routing signal descriptions.

AgentSkills: Teach AI Agents How to Execute Tasks
The article describes a gap in many LLM-based agent applications: agents often know what to do but not how to do it reliably. It introduces AgentSkills (aka Procedure Skills) — self-contained, structured playbooks (commonly formatted as SKILL.md) that bundle YAML frontmatter, step-by-step execution instructions, small automation scripts, domain resources, and output templates. The author explains why embedding full procedures in large system prompts fails (fragility, token waste, inconsistency) and advocates progressive disclosure: a discovery phase that loads only skill names/descriptions and an activation phase that loads full skill assets when a match occurs. The piece gives design principles for effective skills (imperative language, explicit failure states, small composable units) and explains when skills materially improve agent reliability and cost-efficiency.

Make AI Skills Persistent for Agentic Workflows
The article explains that AI "Skills"—small, shareable files that codify procedures—have shifted from a personal prompting shortcut to an organizational, agent-invoked standard. Anthropic added Skills into Excel and PowerPoint sidebars on March 11; the skills format has been adopted across vendors (OpenAI, Microsoft, GitHub, Cursor) and the author says ~500,000 skills now run interoperably. Key changes: agents call skills autonomously, admins can provision skills across organizations, and the same skill files run in developer terminals and productivity apps (M365). The author outlines architectural patterns (progressive disclosure, specialist stack, orchestrator), explains why conventional skill design fails for agentic use, prescribes five elements every skill body needs, and offers four prompts and practical tests to make skills agent-ready. The piece also includes access to a skills repository and team-deployment guidance.
Open Skills Library: Making Agent Workflows Portable
A Substack essay argues that AI agent 'skills'—the procedural knowledge encoded as prompts, runbooks, SKILL.md files and configs—are becoming trapped inside vendor tools (Claude, Codex, Cursor, ChatGPT), creating repeated rebuild costs when teams switch platforms. The author launches "Open Skills," a public library of agent skills and runbooks designed to be visible, movable, inspectable and installable across tools. The piece explains how skills differ from memory and prompts, lists four failure modes that create long-term debt, provides a "work package" checklist to prove ownership of a skill, and demonstrates rebuilding a support-billing workflow that travels across Claude Code, Codex and Cursor. The author frames skill portability as practical work for 2026 that avoids new subscriptions by making existing workflows portable.
