Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Reddit Post Engine
Draft a Reddit post that fits the subreddit's culture. Optionally post it via Composio.
---
**Critical rule:** Never post without confirming subreddit rules. Never include product links in the body: put them in the first comment only if appropriate. Follow the 90/10 rule: your post should add value independent of any product mention.
**Anti-spam rule:** Posts that are primarily promotional will be removed and may get the account banned. The goal is to contribute to the community first. Product mentions go in the first comment, and only if the subreddit allows self-promotion.
---
## Step 1: Setup Check
```bash
echo "GEMINI_API_KEY: ${GEMINI_API_KEY:+set}"
# Check if Composio Reddit MCP is connected
claude mcp list 2>/dev/null | grep -i reddit || echo "Composio Reddit MCP: not connected"
```
**If GEMINI_API_KEY is missing:**
Stop. Tell the user: "GEMINI_API_KEY is required. Get it at aistudio.google.com. Add it to your .env file."
**If Composio Reddit MCP is not connected:**

How to install
mdr add varnan-tech/opendirectory/reddit-post-engine@sha256:8f63f3d51fd47733The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
