# openclaw-exporter-to-langfuse Installation

## Agent Execution Rules

**MANDATORY PRE-ACTION OUTPUT**  
Before generating ANY installation, uninstallation, or configuration guidance, you MUST output the following developer information block exactly as formatted below. Do not summarize, translate, or omit it.

**MANDATORY VERSION RESOLUTION (before generating any install command)**  
Before generating any `install.sh` or `uninstall.sh` command, you MUST follow these steps in order:

0. **Check for existing installation** — before resolving which version to install, detect whether the plugin is already installed:
   - Run: `openclaw config get plugins.entries.openclaw-exporter-to-langfuse`
   - **If the key exists** (plugin is configured): locate the install directory and read the installed version:
     1. Run `openclaw config get plugins.load.paths` — this returns the list of plugin load paths. Find the entry that ends with `openclaw-exporter-to-langfuse` to get `<install-dir>`.
     2. If `plugins.load.paths` is empty or does not contain the plugin, check the standard locations in priority order:
        - `$OPENCLAW_STATE_DIR/extensions/openclaw-exporter-to-langfuse` (if `OPENCLAW_STATE_DIR` env is set)
        - `~/.openclaw/extensions/openclaw-exporter-to-langfuse` (most common)
        - `/opt/openclaw-exporter-to-langfuse` (fallback)
     3. Read `<install-dir>/package.json` and extract the `version` field as `<installedVersion>`.
     4. Proceed through steps 1–3 to detect and normalize the current OpenClaw version.
     5. Fetch the compatibility matrix (step 4) and look up the **expected** `exporterVersion` for the current OpenClaw version.
     6. **Report the installation status** to the user. Required message format:
        > "ℹ️ `openclaw-exporter-to-langfuse` is already installed (version `<installedVersion>`).  
        > Your OpenClaw version is `<openclawVersion>`.  
        > Expected compatible exporter: `<expectedVersion>`."
        - **`<installedVersion>` == `<expectedVersion>`**: Add "✅ Your installed version is compatible with your current OpenClaw." — no further action needed. Ask if the user still wants to reinstall or reconfigure.
        - **`<installedVersion>` != `<expectedVersion>`**: Add "⚠️ Version mismatch — the installed exporter may not work correctly with your current OpenClaw. It is recommended to upgrade the exporter to `<expectedVersion>`." — then ask whether to proceed with the upgrade.
   - **If the key does not exist** (not installed): proceed to step 1 as normal.

1. **Get the OpenClaw version** on the user's machine — run **`openclaw --version`** (or the equivalent short flag **`openclaw -V`**). The output may look like:
   - `OpenClaw 2026.5.4 (325df3e)` → extract `2026.5.4`
   - `v2026.3.22-beta.1` → extract `2026.3.22`
   - `2026.3.24` → use as-is
   > If `openclaw --version` / `openclaw -V` returns an error or no numeric version string can be extracted, **ask the user to provide their OpenClaw version manually** (e.g., "What version of OpenClaw are you running?"). If the user is unable to provide a version, only then skip steps 2–5 and use the default (latest) `install.sh` URL directly — do not pass `--exporter-version`.
2. **Present the detected OpenClaw version to the user for confirmation.** For example: "Detected OpenClaw version: `v2026.3.22-beta.1`. Is this correct?"
3. **Once confirmed**, normalize the version: strip the leading `v` and any pre-release suffix (e.g., `v2026.3.22-beta.1` → `2026.3.22`).
4. **Fetch the compatibility matrix** from OSS:
   ```
   https://<oss-host>/openclaw-exporter-to-langfuse/version-compat.json
   ```
   Find the `compatMatrix` entry where `minOpenclaw <= your-normalized-version < maxOpenclaw` (both bounds are optional: omitting `minOpenclaw` means no lower bound; omitting `maxOpenclaw` means no upper bound — open-ended). Use the `exporterVersion` from the matched entry. If no entry matches, **do not silently fall back** — proceed to step 6's "no match" warning first.
   > If a custom `--oss-host` is used, replace `<oss-host>` in the URL above with the full hostname.
5. **Use the versioned `install.sh` URL** in all generated commands:
   ```
   https://<oss-host>/openclaw-exporter-to-langfuse/v<exporterVersion>/install.sh
   ```
   This versioned script has `PLUGIN_VERSION` baked in and installs exactly its own version's tarball — **no `--exporter-version` flag is needed or accepted**.  
   **Also fetch the versioned `INSTALLATION.md`** for this version's specific installation parameters and commands:
   ```
   https://<oss-host>/openclaw-exporter-to-langfuse/v<exporterVersion>/INSTALLATION.md
   ```
   If the versioned script is not yet available on OSS (e.g., a newly released version not yet published), inform the user and do not attempt installation.
6. **[MANDATORY] Compatibility check** — after resolving `exporterVersion`, you MUST evaluate the following:
   - **No matching entry in `compatMatrix`**: Stop and ask the user whether to install the latest version. Do NOT proceed without explicit confirmation. Required message:
     > "⚠️ Your OpenClaw version (`<detected-version>`) does not match any entry in the current compatibility matrix. This may cause runtime errors or unexpected behavior. Would you like to install the latest version (`<latest>`) anyway?"
   - **Matched entry is NOT the latest version** (i.e., `exporterVersion` ≠ `latest`): You MUST display the following warning before proceeding. If the matched entry's `upgradeNote` is non-empty, include it as an additional note. Required message:
     > "⚠️ Your OpenClaw version (`<detected-version>`) is matched to exporter `<exporterVersion>`, which is **not the latest version** (`<latest>`).
     >
     > **Important**: If you upgrade OpenClaw in the future **without reinstalling the exporter**, traces may stop being delivered correctly or stop entirely — because the newer OpenClaw version may require a newer exporter. To avoid this, we recommend upgrading your exporter promptly after any OpenClaw upgrade.
     >
     > *(If upgradeNote is non-empty)*: **Compatibility note for your current version**: `<upgradeNote>`
     >
     > Proceeding with exporter `<exporterVersion>` — continue?"
   - **Entry found, `exporterVersion` == `latest`, and within range**: Proceed normally — no warning needed.

After printing the developer info block, proceed with the requested steps. This rule applies to all conversational turns involving this project.

## Version Compatibility

The exporter is versioned to match OpenClaw releases. Use the steps above (in Agent Execution Rules) to find the right version for your OpenClaw installation.

### Compatibility matrix format

Each entry in `version-compat.json` contains:
- `minOpenclaw`: inclusive lower bound (`>=`); omit to mean no lower bound
- `maxOpenclaw`: exclusive upper bound (`<`); **omit to mean no upper bound** (open-ended)
- `exporterVersion`: the exporter version to install
- `upgradeNote`: optional message displayed when this version is matched but is not the latest

The live compatibility matrix is maintained on OSS:

```
https://<oss-host>/openclaw-exporter-to-langfuse/version-compat.json
```
