# Moraine

![Moraine Banner](https://github.com/user-attachments/assets/efa723e6-bcc9-4402-bbdf-083297f7e1e2)

[![Docs](https://github.com/eric-tramel/moraine/actions/workflows/docs-deploy.yml/badge.svg)](https://eric-tramel.github.io/moraine/)

Moraine is a local trace stack for agent work. It indexes sessions from agent
harnesses such as Codex, Claude Code, Qwen Code, Kiro CLI, Kimi CLI, NAC,
OpenCode, Hermes, Pi Coding Agent, and Prime Agent into ClickHouse, serves a
monitor UI, and exposes MCP retrieval over the indexed history.

Agents get searchable long-term memory through MCP. You get a unified local
record of what happened across providers, including tools, tokens, and
conversation history.

Moraine is under active development. Config keys, schemas, and MCP tools can
change across minor releases.

## Supported Agent Harnesses

Moraine ships session trace ingestion adapters for these agent harnesses:

| Harness | Config value | Session traces ingested |
| --- | --- | --- |
| [Codex](https://developers.openai.com/codex) | `codex` | JSONL session files under `~/.codex/sessions` |
| [Claude Code](https://code.claude.com/docs/en/overview) | `claude-code` | JSONL project session files under `~/.claude/projects` |
| [Kiro CLI](https://kiro.dev/docs/cli/) | `kiro-cli` | Paired JSONL transcripts and JSON metadata under `$KIRO_HOME/sessions/cli` when set, or `~/.kiro/sessions/cli` |
| [Kimi CLI](https://moonshotai.github.io/kimi-cli/en/) | `kimi-cli` | `wire.jsonl` session traces under `~/.kimi/sessions` |
| [Qwen Code](https://github.com/QwenLM/qwen-code) | `qwen-code` | JSONL chat records under `~/.qwen/projects/*/chats` |
| [NAC](https://github.com/arcee-ai/nac) | `nac` | Parent sessions and managed-worker episodes from setup-resolved `store.db` (`nac_sqlite` format) |
| [OpenCode](https://opencode.ai/) | `opencode` | SQLite session history from `~/.local/share/opencode/opencode*.db` (default on; `opencode_sqlite` format) |
| [Cursor](https://cursor.com/docs) | `cursor` | Agent transcript JSONL under `~/.cursor/projects` (default on); Cursor IDE chat history from `state.vscdb` SQLite databases (default on; `cursor_sqlite` format) |
| [Hermes](https://hermes-agent.nousresearch.com/docs/) | `hermes` | Live session JSON and trajectory JSONL traces |
| [Pi Coding Agent](https://pi.dev/docs/latest) / OMP | `pi-coding-agent` | JSONL session trees under `~/.pi/agent/sessions` and `~/.omp/agent/sessions` |
| [Prime Agent](https://github.com/PrimeIntellect-ai/prime-agent) | `prime-agent` | Root JSONL sessions under `~/.prime/agent/sessions` and RLM child transcripts under `~/.prime/agent/session-artifacts` |

## Quickstart

```bash
uv tool install moraine-cli
moraine setup
moraine up
```

`moraine setup` creates or repairs `~/.moraine/config.toml` and guides plugin or
MCP registration for detected agent harnesses.

For NAC, setup preserves unrelated `config.toml` settings, registers
`[mcp_servers.moraine]`, and adds the resolved SQLite store only when its path
is stable and absolute. Relative or per-launch `--store-path` databases require
the manual source snippet printed by setup.

The monitor UI runs at `http://127.0.0.1:8080` by default.

For release bundles, upgrades, project-scoped setup, and other harnesses, see the
[Quickstart and Installation](https://eric-tramel.github.io/moraine/quickstart.html).

## Connect Agent Harnesses

Use `moraine setup` to install or update the Moraine plugins for Claude Code,
Codex, and Hermes; install Kiro CLI's global steering and MCP registration; or
register Moraine MCP for supported harnesses such as Qwen Code, NAC, OpenCode,
Cursor, Kimi CLI, Pi Coding Agent, OMP, and Prime Agent. The integrations use
the installed Moraine bundle and the running local stack. For Kiro CLI and Prime
Agent, Moraine also resolves ingest paths from `KIRO_HOME` and
`PRIME_AGENT_CODING_AGENT_DIR`, respectively.

Start a new agent session after installing an integration. The Claude Code,
Codex, and Hermes plugins provide named Moraine skills. Prime Agent receives a
managed Python-backed `moraine` skill, while Kiro CLI receives equivalent search
and realtime guidance from its managed global steering file.
Moraine MCP tools are exposed with each harness's MCP naming scheme. Then ask:

```text
What are my agents doing right now?
```

The user-scoped plugins can search the host-wide Moraine history visible to your
user. For project-scoped setup, duplicate MCP cleanup, and other clients, see
[Agent MCP Search](https://eric-tramel.github.io/moraine/agent-mcp-search/index.html).

## Agent Harness Guidance

The Claude Code, Codex, and Hermes plugins already bundle Moraine search
guidance, and `moraine setup integrations kiro-cli --yes` installs it under
`$KIRO_HOME/steering` when set, or `~/.kiro/steering` otherwise. If you use
manual MCP registration or another harness, add the following guidance to its
global instructions, such
as that Kiro steering path, `~/.codex/AGENTS.md` for Codex, or
`~/.claude/CLAUDE.md` for Claude Code:

```markdown
- You have access to all past agent sessions (whether codex, claude, hermes, etc., anything) via moraine search tools.
- Any time the user asks about information not located within your context, that you can't see or don't know, but implies that you *should* know, it is because it was a past conversation. You can reference and search for this conversation with moraine search tools or session listing.
- Moraine search tooling is built around BM25 keyword search, so target your queries to keywords rather than questions. There is no semantic search.
- Successful keyword searches often go from broad to narrow. Sometimes this narrowing isn't successful, in which case, you can always back up and try a different path.
- Moraine has a *real-time* view of agent sessions. You can use it to peek on active AI agent sessions, including your own, sessions running in different harnesses, sessions that are sub-agents of your current conversation, or even their subagents. All agent work, in realtime, is visible to you.
```

With this you can do operations like the following:

```
claude -p "What are my agents doing right now?"
codex exec "What are my agents doing right now?"
hermes -z "What are my agents doing right now?"
kiro-cli chat --no-interactive "What are my agents doing right now?"
```

## Development

```bash
cargo build --workspace --locked
cargo test --workspace --locked
cargo fmt --all -- --check
```

The repository-managed pre-commit hook can be installed with:

```bash
make hooks-install
```

Moraine contributor workflows are available through the repository's Codex
plugin and Kiro workspace agent with native Agent Skills. See
[Agent Contributor Workflows](docs/development/agent-contributor-workflows.md)
for installation and usage.

To put the current checkout (tip-of-branch, no tagged release needed) onto your
host for testing, build and install it over the active `moraine` on your PATH:

```bash
make install
```

This release-builds the host target and installs through the same
`scripts/install.sh` path end users get. ClickHouse is skipped by default
(`make install INSTALL_ARGS="--with-clickhouse"` to include it). See
`scripts/dev/install-host.sh --help` for the full set of options.
