# MKTT-WP-0008: Agent Working Memory Context Cache

## Purpose

Create activatable context packages that let agents drop, reactivate, and
reuse project knowledge efficiently while preserving provenance and policy
metadata.

## P8.1 - Define context package schema

```task
id: MKTT-WP-0008-T001
status: todo
priority: high
state_hub_task_id: "21ee9c37-4add-4886-bd03-a7bb4b20e957"
```

Represent source spans, summaries, token estimates, freshness, provenance,
policy labels, and retrieval recipes.

## P8.2 - Implement package creation from queries

```task
id: MKTT-WP-0008-T002
status: todo
priority: high
state_hub_task_id: "4df06b93-13ce-41fb-a8c3-f04d4ad9d752"
```

Create context packages from simple selectors, cached search results, or
manifest files.

## P8.3 - Implement activation lifecycle

```task
id: MKTT-WP-0008-T003
status: todo
priority: medium
state_hub_task_id: "9f3d9792-d655-482d-bae0-262df5fc0136"
```

Support activate, deactivate, refresh, and explain operations for a package.

## P8.4 - Add memory namespaces

```task
id: MKTT-WP-0008-T004
status: todo
priority: medium
state_hub_task_id: "2d090494-0e10-44cd-8e2d-c418d7530b27"
```

Support project, user, agent, thread, and task namespaces without hard-coding
any external agent platform.

## P8.5 - Add summary layers

```task
id: MKTT-WP-0008-T005
status: todo
priority: medium
state_hub_task_id: "4d1cf970-3d6d-4bd5-8da9-ec2399aa7efe"
```

Support deterministic summaries first, then optional LLM-generated summaries
through an injected adapter.

## P8.6 - Add CLI commands

```task
id: MKTT-WP-0008-T006
status: todo
priority: medium
state_hub_task_id: "2f18386c-9d2c-4af1-b8e2-75cb487c1692"
```

Add:

```text
mkt context pack <manifest-or-query>
mkt context activate <package-id>
mkt context explain <package-id>
mkt context refresh <package-id>
```

## Exit Criteria

- Agents can reactivate project context by stable id.
- Context packages show included sources and token budgets.
- Memory writes remain explicit and inspectable.
