+description: Force a Mattermost sync using the configured local script
+---
+
+Use the configured Mattermost sync command to fetch fresh communication context.
+
+Preferred command sources:
+
+- `FIDELITY_MATTERMOST_SYNC_CMD`
+- fallback: `bash scripts/mattermost/sync.sh`
+
+Run the command and use its output as fresh communication context:
+
+!`if [ -n "$FIDELITY_MATTERMOST_SYNC_CMD" ]; then bash -lc "$FIDELITY_MATTERMOST_SYNC_CMD"; elif [ -f scripts/mattermost/sync.sh ]; then bash scripts/mattermost/sync.sh; else echo "No Mattermost sync command is configured."; fi`
+
+Then:
+
+- if the command fails, stop there and do not edit any workspace files
+- if no `ai/inbox/mattermost-latest.md` exists after the sync attempt, do not update logs or stable context
+- inspect `ai/inbox/mattermost-latest.md` if it exists
+- decide whether the new information belongs in today's log, current state, or stable project context
+- update the workspace only if the sync succeeded and durable facts were learned
+
+Return:
+
+1. What was synchronized
+2. Which files were updated
+3. What still needs human confirmation

+This directory contains helpers that automate:

 - manager update drafting
 - Mattermost-ready message formatting
 
-No automation has been implemented yet. The current workflow is document-driven.

+
+- `scripts/mattermost/`
+
+Recommended default command:
+
+```bash
+bash scripts/mattermost/sync.sh

+
+Bootstrap command:
+
+```bash

+Example:
+

+Expected behavior:
+
+- print the latest relevant Mattermost context to stdout
+- avoid interactive prompts
+- return a non-zero exit code on failure
+
+OpenCode can then use that output to refresh `ai/inbox/mattermost-latest.md` proactively.

+# Mattermost Sync
+
+This directory contains the workspace-local Mattermost extractor used by OpenCode to refresh communication context.
+
+## Files
+
+- `mattermost_context.py`
+  Extracts recent Mattermost messages as JSONL.
+- `sync.sh`
+  Stable wrapper intended to be called by OpenCode.
+- `.env.example`
+  Example configuration without secrets.
+- `requirements.txt`
+  Reserved for future optional dependencies.
+
+## Recommended Setup
+
+1. Copy `.env.example` to `.env`.
+2. Fill in your Mattermost values.
+3. Create a local virtual environment if you want an isolated runtime.
+
+Example:
+
+```bash
+cd scripts/mattermost
+bash bootstrap.sh
+```
+
+## Usage
+
+Manual run:
+
+```bash
+bash scripts/mattermost/sync.sh
+```
+
+OpenCode can use this script directly. If `FIDELITY_MATTERMOST_SYNC_CMD` is not set, the workspace plugins will fall back to this wrapper automatically.
+
+## Bootstrap
+
+You can initialize the local runtime with:
+
+```bash
+bash scripts/mattermost/bootstrap.sh
+```
+
+This will:
+
+- create `.venv/` if missing
+- create `.env` from `.env.example` if needed
+
+The current extractor uses only the Python standard library, so no third-party install is required.

 - Project instructions load automatically from `opencode.json`.
 - Root rules also load automatically from `AGENTS.md`.
 - The main context command reads the stable workspace files plus today's log.
+- Mattermost context can be refreshed into `ai/inbox/` using your existing local sync script.
 - Daily updates go back into the workspace, so later prompts inherit better context.
 - The local compaction plugin helps preserve the most important workspace context during long sessions.
 - This reduces reliance on fragile session memory.
