# Chat Session Briefing
A system for maintaining project continuity across Claude sessions. Session briefings are
structured documents that serve as the primary source of truth when resuming work — they
tell a fresh Claude instance everything it needs to know to be productive immediately.
This is the **chat variant** — for claude.ai (web or desktop), where there's no repo, no
`CLAUDE.md`/`AGENTS.md`, and no git, so the briefing is a single self-contained markdown document
that holds everything. (For a coding agent that runs in a repo with a context file + git, use
`agent-session-briefing` instead — it offloads timeless reference to the context file and adds a
cross-project *constellation* rollup.)
## Why this matters
Claude has no memory between sessions. Without a well-maintained briefing, every new session
starts cold — context is lost, decisions get revisited, work gets duplicated, and downstream
effects get missed. A good session briefing eliminates this. It is the project's institutional
memory.
## Two modes
This skill operates in two modes:
1. **Cold start** — The user is beginning a new multi-session project. Create the first
briefing document (v1.0) by interviewing for context, then producing a structured doc.
2. **Continuation** — The user has an existing briefing. When updating, follow the carry-forward
rules precisely and produce an incremented version.
Detect which mode applies from context. If the user loads a briefing document or references
