## What hindsight does, in the publisher's words

A portable Agent Plugin (spec 1.0.0) that gives any compatible agent client long-term memory via Hindsight.

Agent Plugins is the vendor-neutral standard (AWS, Cursor, GitHub/Microsoft, OpenAI, Vercel) for packaging Agent Skills + MCP servers into one distributable plugin. At launch it is supported by ChatGPT/Codex, Cursor, GitHub Copilot, Kiro, and VS Code.

This is the portable front door to Hindsight: one artifact, every supported client. It carries the same retain / recall / reflect memory as our per-IDE integrations, but as a single standards-based bundle instead of N hand-rolled configs.

- mcp.json points the client at Hindsight's built-in MCP server (retain, recall, reflect, knowledge pages, and more: see MCP Server docs). The plugin is transport-only; all memory logic stays server-side.
- skills/hindsight-memory/SKILL.md is loaded into the agent's context so it knows when to reach for memory, not just that the tools exist.

## Skills

- hindsight-memory: Long-term memory for the agent via Hindsight. Use to recall relevant past context before answering, retain durable facts as you learn them, and reflect over accumulated memory for the "why" behind a decision. Load whenever continuity across sessions matters: the user refers to earlier work, states…

Descriptions come from the frontmatter of each SKILL.md, punctuation lightly normalized.
