Discord Reader Agent Skill

Discord Skill (Read-Only)

Reads Discord for financial research using opencli, a universal CLI tool that bridges desktop apps and web services to the terminal via Chrome DevTools Protocol (CDP).

This skill is read-only. It is designed for financial research: searching trading server discussions, monitoring crypto/market groups, tracking sentiment in financial communities, and reading messages. It does NOT support sending messages, reacting, editing, deleting, or any write operations.

Important: opencli connects to the Discord desktop app via CDP — no bot account or token extraction needed. Just have Discord Desktop running.

Step 1: Ensure opencli Is Installed and Discord Is Ready

Current environment status:

!`(command -v opencli && opencli discord-app status 2>&1 | head -5 && echo "READY" || echo "SETUP_NEEDED") 2>/dev/null || echo "NOT_INSTALLED"`

If the status above shows READY, skip to Step 2. If NOT_INSTALLED, install first:

# Install opencli globally
npm install -g @jackwener/opencli

If SETUP_NEEDED, guide the user through setup:

Setup

opencli requires Node.js >= 21. It connects to Discord Desktop via CDP (Chrome DevTools Protocol) — no Browser Bridge extension is needed for the Discord adapter. Two things are required:

• Start Discord with remote debugging enabled:

# macOS
/Applications/Discord.app/Contents/MacOS/Discord --remote-debugging-port=9232 &

# Linux
discord --remote-debugging-port=9232 &

• Set the CDP endpoint environment variable:

export OPENCLI_CDP_ENDPOINT="http://127.0.0.1:9232"

Add this to your shell profile (.zshrc / .bashrc) so it persists across sessions.

• Verify connectivity:

opencli discord-app status

Common setup issues

| Symptom | Fix |

|---------|-----|

| CDP connection refused | Ensure Discord is running with --remote-debugging-port=9232 |

| OPENCLI_CDP_ENDPOINT not set | Run export OPENCLI_CDP_ENDPOINT="http://127.0.0.1:9232" |

| status shows disconnected | Restart Discord with the CDP flag and retry |

| Discord not on expected port | Check that no other app is using port 9232, or use a different port |

Tip: create a shell alias

alias discord-cdp='/Applications/Discord.app/Contents/MacOS/Discord --remote-debugging-port=9232 &'

Step 2: Identify What the User Needs

Match the user's request to one of the read commands below, then use the corresponding command from references/commands.md.

| User Request | Command | Key Flags |

|---|---|---|

| Connection check | opencli discord-app status | — |

| List servers | opencli discord-app servers | -f json |

| List channels | opencli discord-app channels | -f json |

| List online members | opencli discord-app members | -f json |

| Read recent messages | opencli discord-app read | N (count), -f json |

| Search messages | opencli discord-app search "QUERY" | -f json |

Note: opencli operates on the currently active server and channel in Discord. To read from a different channel, the user must navigate to it in the Discord app first, or use the channels command to identify what's available.

Step 3: Execute the Command

General pattern

# Use -f json or -f yaml for structured output
opencli discord-app servers -f json
opencli discord-app channels -f json

# Read recent messages from the active channel
opencli discord-app read 50 -f json

# Search for financial topics in the active channel
opencli discord-app search "AAPL earnings" -f json
opencli discord-app search "BTC pump" -f json

Key rules

• Check connection first — run opencli discord-app status before any other command
• Use -f json or -f yaml for structured output when processing data programmatically
• Navigate in Discord first — opencli reads from the currently active server/channel in the Discord app
• Start with small reads — use opencli discord-app read 20 unless the user asks for more
• Use search for keywords — opencli discord-app search uses Discord's built-in search (Cmd+F / Ctrl+F)
• NEVER execute write operations — this skill is read-only. opencli exposes discord-app send and discord-app delete commands; do not invoke them. Do not send messages, react, edit, delete, or manage server settings.

Output format flag (-f)

| Format | Flag | Best for |

|---|---|---|

| Table | -f table (default) | Human-readable terminal output |

| JSON | -f json | Programmatic processing, LLM context |

| YAML | -f yaml | Structured output, readable |

| Markdown | -f md | Documentation, reports |

| CSV | -f csv | Spreadsheet export |

Typical workflow for reading a server

# 1. Verify connection
opencli discord-app status

# 2. List servers to confirm you're in the right one
opencli discord-app servers -f json

# 3. List channels in the current server
opencli discord-app channels -f json

# 4. Read recent messages (navigate to target channel in Discord first)
opencli discord-app read 50 -f json

# 5. Search for topics of interest
opencli discord-app search "price target" -f json

Step 4: Present the Results

After fetching data, present it clearly for financial research:

• Summarize key content — highlight the most relevant messages for the user's financial research
• Include attribution — show username, message content, and timestamp
• For search results, group by relevance and highlight key themes, sentiment, or market signals
• For server/channel listings, present as a clean table with names and types
• Flag sentiment — note bullish/bearish sentiment, consensus vs contrarian views
• Treat sessions as private — never expose CDP endpoints or session details

Step 5: Diagnostics

If something isn't working, check:

• Is Discord running with CDP?

# Check if the port is open
lsof -i :9232

• Is the environment variable set?

echo $OPENCLI_CDP_ENDPOINT

• Can opencli connect?

opencli discord-app status

If all checks fail, restart Discord with the CDP flag:

/Applications/Discord.app/Contents/MacOS/Discord --remote-debugging-port=9232 &
export OPENCLI_CDP_ENDPOINT="http://127.0.0.1:9232"
opencli discord-app status

Error Reference

| Error | Cause | Fix |

|-------|-------|-----|

| CDP connection refused | Discord not running with CDP or wrong port | Start Discord with --remote-debugging-port=9232 |

| OPENCLI_CDP_ENDPOINT not set | Missing environment variable | export OPENCLI_CDP_ENDPOINT="http://127.0.0.1:9232" |

| No active channel | Not viewing any channel in Discord | Navigate to a channel in the Discord app |

| Rate limited | Too many requests | Wait a few minutes, then retry |
