Context Mod (CM) is an event-based, reddit moderation bot built on top of snoowrap and written in typescript.
It is designed to help fill in the gaps for automoderator in regard to more complex behavior with a focus on user-history based moderation.
An example of the above that Context Bot can do:
- On a new submission, check if the user has also posted the same link in N number of other subreddits within a timeframe/# of posts
- On a new submission or comment, check if the user has had any activity (sub/comment) in N set of subreddits within a timeframe/# of posts
In either instance Context Bot can then perform any action a moderator can (comment, report, remove, lock, etc...) against that user, comment, or submission.
Feature Highlights for Moderators:
- Complete bot autonomy. YAML config is stored in your subreddit's wiki (like automoderator)
- Simple rule-action behavior can be combined to create complex behavior detection
- Support Activity filtering based on:
- Author criteria (name, css flair/text, age, karma, moderator status, Toolbox User Notes, and more!)
- Activity state (removed, locked, distinguished, etc...)
- State of Subreddit Activity is in Subreddit (nsfw, name, profile, etc...)
- Rules and Actions support named references -- write once, reference anywhere
- Powerful logic control (if, then, goto)
- Delay/re-process activities using arbitrary rules
- Image Comparisons via fingerprinting and/or pixel differences
- Repost detection with support for external services (youtube, etc...)
- Event notification via Discord
- Web interface for monitoring, administration, and oauth bot authentication
- Placeholders (like automoderator) can be configured via a wiki page or raw text and supports mustache templating
- Partial Configurations -- offload parts of your configuration to shared locations to consolidate logic between multiple subreddits
- Guest Access enables collaboration and easier setup by allowing temporary access
- Toxic content prediction using moderatehatespeech.com machine learning model
Feature highlights for Developers and Hosting (Operators):
- Server/client architecture
- Default/no configuration runs "All In One" behavior
- Additional configuration allows web interface to connect to multiple servers
- Each server instance can run multiple reddit accounts as bots
- Global/subreddit-level caching of Reddit APIs responses and CM results
- Database Persistence using SQLite, MySql, or Postgres
- Audit trails for bot activity
- Historical statistics
- Docker container and docker-compose support
- Easy, UI-based OAuth authentication for adding Bots and moderator dashboard
- Integration with InfluxDB for detailed time-series metrics and a pre-built Grafana dashboard
Each subreddit using the RCB bot configures its behavior via their own wiki page.
When a monitored Activity (new comment/submission, new modqueue item, etc.) is detected the bot runs through a list of Checks to determine what to do with the Activity from that Event. Each Check consists of :
Is this check for a submission or comment?
A list of Rules to run against the Activity. Triggered Rules can cause the whole Check to trigger and run its Actions
A list of Actions that describe what the bot should do with the Activity or Author of the activity (comment, remove, approve, etc.). The bot will run all Actions in this list.
The Checks for a subreddit are split up into Submission Checks and Comment Checks based on their kind. Each list of checks is run independently based on when events happen (submission or comment).
When an Event occurs all Checks of that type are run in the order they were listed in the configuration. When one check is triggered (an Action is performed) the remaining checks will not be run.
Learn more about the RCB lifecycle and core concepts in the docs.
This guide is for users who want to run their own bot on a ContextMod instance.

This guide is for reddit moderators who want to configure an existing CM bot to run on their subreddit.
See the Moderator's Getting Started Guide
Context Bot's configuration can be written in YAML (like automoderator) or JSON5. Its schema conforms to JSON Schema Draft 7. Additionally, many operator settings can be passed via command line or environmental variables.
- For operators (running the bot instance) see the Operator Configuration guide
- For moderators consult the Subreddit Configuration Docs

CM comes equipped with a dashboard designed for use by both moderators and bot operators.
- Authentication via Reddit OAuth -- only accessible if you are the bot operator or a moderator of a subreddit the bot moderates
- Connect to multiple ContextMod instances (specified in configuration)
- Monitor API usage/rates
- Monitoring and administration per subreddit:
- Start/stop/pause various bot components
- View statistics on bot usage (# of events, checks run, actions performed) and cache usage
- View various parts of your subreddit's configuration and manually update configuration
- View real-time logs of what the bot is doing on your subreddit
- Run bot on any permalink
A bot oauth helper allows operators to define oauth credentials/permissions and then generate unique, one-time invite links that allow moderators to authenticate their own bots without operator assistance. Learn more about using the oauth helper.

A similar helper and invitation experience is available for adding subreddits to an existing bot.
A built-in editor using monaco-editor makes editing configurations easy:
- Automatic JSON or YAML syntax validation and formatting
- Automatic Schema (subreddit or operator) validation
- All properties are annotated via hover popups
- Unauthenticated view via
yourdomain.com/config - Authenticated view loads subreddit configurations by simple link found on the subreddit dashboard
- Switch schemas to edit either subreddit or operator configurations
- Overall stats (active bots/subreddits, api calls, per second/hour/minute activity ingest)
- Over time graphs for events, per subreddit, and for individual rules/check/actions
