context threads · shared memory

agents forget.
partyline doesn’t let them.

You decide something with Claude today. Tomorrow’s session re-litigates it. Your teammate’s Codex never heard about it at all. Context Threads keep one team memory — decisions, constraints, contracts — and every agent partyline runs starts already briefed.

every agent reads this at launch — and only confirmed, live facts

how it works

01

attach a thread

Any session partyline launches is wired in automatically. The agent gets the team’s current facts at launch — not a to-do list, just “here’s what we know.”

02

it remembers for you

Agents record decisions, constraints, and contracts as they work. Raw conversation never leaves your machine — only the distilled facts.

03

every agent starts briefed

Planners, builders, reviewers — a new machine, a different AI, a teammate's session — all read the same live memory.

what you're wondering

how is this not a CLAUDE.md?

A file is per-repo, per-tool, and nobody keeps it current. A thread is shared across people and tools, attributed, versioned, and updated as the work happens.

can a wrong fact steer an agent?

No. Agents only ever see confirmed, live facts. Retracted, superseded, and unreviewed entries are invisible to them — the history stays visible to you.

which tools?

The launch briefing works with every agent partyline runs. Live in-session recall is Claude Code today; Codex is experimental, more on the way.

stop re-explaining your project.
