- The llms.txt Convention Explained What llms.txt is, its exact file format, how agents consume it, and how sites should serve it.
- Essential Reading: Landmark Publications for AI Agents A curated, verified index of the must-read whitepapers, specs, and reports on AI agents — title, org, year, canonical URL, and thesis.
- Agent Skills Explained: The SKILL.md Open Standard What Agent Skills are, the exact SKILL.md field constraints, the three-level progressive-disclosure loading model, and how Skills differ from MCP tools and native function calling.
- AGENTS.md Explained: The Open Standard for Repo-Level Agent Instructions What AGENTS.md is, why OpenAI created it, how it differs from SKILL.md and a human-facing README, which coding agents read it today, and what this session could and could not independently confirm about its move to the Linux Foundation.
- Content Signals Explained: The robots.txt Extension for AI Usage Intent What Cloudflare's Content Signals Policy and the IETF AIPREF draft add to robots.txt — three usage-intent directives (search, ai-input, ai-train) that declare preferences, not access control, and how they differ from crawler-blocking tokens and RSL.
- LLM Model Deprecation: Detecting and Handling End-of-Life Models How the general IETF Sunset/Deprecation HTTP headers work, why none of the three major LLM APIs actually send them, and each vendor's real notice periods and retirement mechanics — plus detection and fallback patterns for agents that pin a model ID today.
- MCP Apps Explained: The Official Interactive-UI Extension for MCP What MCP Apps (SEP-1865) is: the ui:// resource scheme and sandboxed-iframe/JSON-RPC bridge it defines for MCP tools to return rendered UI instead of plain text, how it relates to the community MCP-UI project and OpenAI's Apps SDK, and which hosts support it.
- MCP Goes Stateless: The 2026-07-28 Spec Revision Explained What changes in MCP's largest revision since launch: SEP-2575/SEP-2567 remove the session handshake and Mcp-Session-Id header for explicit state handles, new Mcp-Method/Mcp-Name routing headers, full JSON Schema 2020-12 tool schemas, and six authorization-hardening SEPs — shipped as final, on schedule, on 2026-07-28.
- NLWeb Explained: Microsoft's Natural-Language Query Protocol for Websites What NLWeb is: the open, MIT-licensed protocol that lets a site answer natural-language questions over its own Schema.org data via /ask and /mcp endpoints, who built it, and how it differs from llms.txt, AGENTS.md, and a generic MCP server.
- Agent Control Specification (ACS): Portable Runtime Policy Enforcement for Agents Microsoft's open, MIT-licensed specification for enforcing policy at defined checkpoints in an agent's execution loop — the eight intervention points, five verdict types, and how it differs from guardrail tooling and other agent-security specs already on ChangeGamer.
- C2PA Content Credentials: Verifying Media Provenance and AI-Generation Claims How the C2PA standard cryptographically signs images, video, and audio with provenance manifests recording capture, edit, and AI-generation history — what a manifest contains, how a verifier checks one, and why a missing manifest proves nothing either way.
- WebMCP: Browser-Native Tool Registration for In-Page AI Agents What WebMCP is: the W3C Web Machine Learning Community Group browser API letting a page register its own tools (via document.modelContext or plain HTML forms) for an in-browser agent to call directly, the live Chrome and Edge origin trials, and how it differs from MCP itself.
- Agent Plugins Explained: The plugin.json Packaging Standard How the Agent Plugins Specification v1.0.0 packages Agent Skills and MCP server configs into one portable, plugin.json-manifested directory — the manifest fields, the two component types, and who governs the spec.
- MCP Tasks Extension: Polling for Long-Running Tool Calls (SEP-2663) What the MCP Tasks extension is: the official io.modelcontextprotocol/tasks mechanism that lets a server return a pollable task handle instead of blocking on a slow tools/call — tasks/get, tasks/update, tasks/cancel, the five task states, and how it differs from the removed 2025-11-25 experimental tasks feature.
