1. toolkittestenvironment.initialize() missing assembly 📘 Rule violation ⛯ Reliability
The new test wire-up does not pass context.Assembly to ToolkitTestEnvironment.Initialize/Reset, which breaks the required standardized per-assembly test environment lifecycle. This can cause unreliable test setup/cleanup when multiple test assemblies run under the shared toolkit.
Agent Prompt
## Issue description
`TestEnvironmentWireUp` does not call `ToolkitTestEnvironment.Initialize(context.Assembly)` / `Reset(context.Assembly)` as required.
## Issue Context
The repository test infrastructure relies on assembly-scoped initialization/reset to avoid cross-test-project interference.
## Fix Focus Areas
- src/KurrentDB.Plugins.Kontext.Tests/TestEnvironmentWireUp.cs[10-16]

2. Ci misses submodules 🐞 Bug ⛯ Reliability
CI uses actions/checkout without enabling submodule checkout, but the solution now includes libs/Kurrent.Kontext as a git submodule and directly ProjectReferences its csproj, causing restore/build failures in CI and for developers without git submodule update --init.
Agent Prompt
### Issue description
The repo now depends on a git submodule (`libs/Kurrent.Kontext`) at build time via `ProjectReference`, but CI workflows check out the repository without fetching submodules. This causes missing project files during restore/build.
### Issue Context
Workflows using `actions/checkout@v4` must set `submodules: recursive` (or at least `true`) for submodules to be present.
### Fix Focus Areas
- .github/workflows/common.yml[21-73]
- .github/workflows/build-reusable.yml[17-97]
- .github/workflows/build-container-reusable.yml[11-97]
### Suggested change
Update each `actions/checkout@v4` step to include:
```yaml
with:
submodules: recursive
```
If you intentionally do not want submodules in some jobs, then remove the `ProjectReference` dependency and consume `Kurrent.Kontext` as a NuGet package or vendored source instead.

Adds the Kontext plugin — an embedded agent memory and RAG system for KurrentDB that gives AI agents durable, searchable memory backed by KurrentDB events.
Kontext supports any AI agent that can connect to an MCP server over HTTP (Claude Code, Cursor, Windsurf, Copilot, etc.). Importing data into Kontext requires the agent to be able to run
curlor any equivalent HTTP client tool.Configuration
Data stored under
{index}/kontext/. Memory stream is$kontext-memory.Connecting Claude Code
Add
.mcp.jsonto your project root:{ "mcpServers": { "kontext": { "type": "http", "url": "http://localhost:2113/mcp/kontext", "headers": { "Authorization": "Basic YWRtaW46Y2hhbmdlaXQ=" } } } }Try it out
RAG — ask Claude about events in an existing database:
Data Import — load a dataset and explore it:
Agent Memory — insights are retained across sessions:
How it works
The plugin subscribes to
$alland indexes every event using hybrid text + vector search. Agents connect via MCP over HTTP and can search events, retain synthesized facts, and recall them in future sessions.All configuration options
