No rot. No drift.
Code with current context.

Give your AI coding agents high-signal context from your team’s real decisions and lessons learned — always current, portable, and scoped exactly right.

01The model · how ContextStream works

Capture wisdom. Map context. Reuse safely.

One loop, three moves. Built so the right knowledge ends up in the right hands and the right agents — without leaking across projects, clients, or teams.

01CAPTURE WISDOM
Decisions, lessons, preferences, guardrails.
Every time you correct a path, clarify a why, or set a rule — capture it once. Scoped to project, workspace, or team.
DecisionsLessonsPreferencesGuardrailsInsights
02MAP CONTEXT
Knowledge Stream and Atlas connect what matters.
The Stream is what is new. The Atlas is what is connected. Together they give your AI a project that is queryable, not just searchable.
Knowledge StreamKnowledge AtlasIndexed codeLinked docsOpen threads
03REUSE SAFELY
Right context, right scope, every time.
Agents, teammates, clients, and Capsules each get exactly the context they should — and nothing they shouldn't.

02The 5-step context mission

Five moves. From cold project to cited recall.

Hover a step to preview it — or open the full mission to play through every step on demo data.

1
Add project context
Bring in code, docs, tasks. ContextStream builds a project graph in the background.
60s
2
Capture a decision
The why behind a choice — surfaced before related work next time.
45s
3
Capture a lesson
A guardrail that surfaces the next time something similar happens.
40s
4
Verify recall
Ask ContextStream Code what it knows. Watch it cite the decision and lesson with sources.
60s
5
Package a Capsule
A scoped, expiring link a teammate, client, or agent can open.

STEP 2 OF 545s
Capture a decision
The why behind a choice — surfaced before related work next time.
DECISION · WISDOM
Use signed session handoff before refresh.
Refresh-token rotation was racing the active socket. Signing the handoff lets the new session validate against the prior one — kept tail latency under 80ms.

03Knowledge Stream · the living feed

Every decision, lesson, and insight in one feed your AI reads from.

Decisions, lessons, insights, skills, docs, todos, tasks, and sessions flow into a single stream. Your team browses it. Your agents query it. Nothing slips through cracks anymore.

04Knowledge Atlas · the project, mapped

Project history, mapped into agent-ready context.

The Stream is what's new. The Atlas is what's connected. Decisions, lessons, code, docs, and sessions become a queryable graph — so an agent can find the right context, not the most recent one.

Connected, not stored
Decisions and lessons are linked to the code, docs, and sessions they touch. The graph is the index.
Right context, not most recent
When an agent asks about a file, the Atlas returns the wisdom around it — not whatever was last in chat.
Traversable by every tool
Cursor, Claude Code, Cline, and your own agents read the same graph through MCP. One source of truth.
05The differentiator

Correct once. Learn permanently.

When you fix a mistake, clarify a decision, or correct an AI output, ContextStream captures that learning as reusable judgment. Every future session — yours, your team's, your agents' — starts smarter.

06ContextCapsules

Package the right context for the right handoff.

One scoped link. Decisions, plan, docs, open thread, redacted secrets — bundled and time-boxed. A teammate, a client, or an agent picks up your exact context.

TEAMMATE◈
Hand off mid-session
Priya opens the Capsule on Friday. She sees your plan, the 14 decisions, the open 217-turn thread. She picks up cold.
$cs share --with priya@acme --expires 24h
CLIENT◈
Ship a handoff a client can open
Redacted, scoped, single-use. The client sees what they need to see — never your internal env or another client's wisdom.
$cs share --scope client/acme --redact secrets
AGENT◈
Boot an agent with your full context
MCP-grade payload. Decisions, lessons, code understanding, current plan. Agent reads it before any action — and cites it back.
$cs serve --mcp --capsule cap_2k9J
07Built for the way you actually work

Solo. Team. Client work. Agents. One layer.

TEAMS
A shared layer your whole team reads from.
Onboarding capsules. Team decisions. Shared lessons. Every PR review starts informed.
CONSULTANTS
Per-client scope. Safe handoffs. Real leverage.
Each client gets their own context graph. Capsules carry exactly what they should see — and nothing else.
AGENT BUILDERS
MCP-grade context, lessons-aware guardrails.
Agents read the project graph through MCP. Lessons surface before risky calls. No more "help, my agent did the wrong thing."
08Security & governance

The right context, at the right scope.

Wisdom is power. Scopes, redaction, and signed handoffs make sure it goes exactly where you mean it to — and nowhere else.

⊘
Scope-aware capture
Workspace · project · client · personal. Wisdom never leaks across boundaries you didn't set.
◷
Scoped, expiring handoffs
Every Capsule is scoped, time-boxed, and revocable. Cryptographic signing available for verified handoffs.
◬
Redaction by default
Env vars, API keys, and matched secrets stripped before any handoff. Verifiable diff on every Capsule.
◉
Local-only mode
Mark wisdom as local-only. Never syncs, never reaches an agent. Your laptop stays your laptop.
