Send and read Slack messages from the command line using slackcli (shaharia-lab/slackcli).
Download the binary:
curl -sL -o /usr/local/bin/slackcli \
"https://github.com/shaharia-lab/slackcli/releases/download/v0.1.1/slackcli-linux"
chmod +x /usr/local/bin/slackcli
macOS (Intel): replace slackcli-linux with slackcli-macos
macOS (Apple Silicon): replace with slackcli-macos-arm64
slackcli uses browser session tokens (xoxc + xoxd) - no Slack app creation required.
./scripts/extract-tokens <workspace-url>
This walks the user through extracting tokens from browser DevTools.
slackcli auth login-browser \
--xoxd="xoxd-..." \
--xoxc="xoxc-..." \
--workspace-url=https://your-workspace.slack.com
slackcli auth list
Use slackcli conversations list to discover channels and their IDs:
# List all channels
slackcli conversations list
# Filter output
slackcli conversations list | grep -i "channel-name"
# Send to a channel (use channel ID from conversations list)
slackcli messages send --recipient-id=C0XXXXXXXX --message="Hello from CLI"
# Send to a DM (use user's DM channel ID)
slackcli messages send --recipient-id=D0XXXXXXXX --message="Hey"
# Reply in a thread
slackcli messages send --recipient-id=C0XXXXXXXX --message="Thread reply" --thread-ts=1769756026.624319
The --recipient-id is always a channel ID (C...) or DM channel ID (D...).
# Read last N messages from a channel
slackcli conversations read C0XXXXXXXX --limit=10
# Read as JSON (for parsing)
slackcli conversations read C0XXXXXXXX --limit=10 --json
# Read a thread
slackcli conversations read C0XXXXXXXX --thread-ts=1769756026.624319
slackcli conversations list
Returns all public channels, private channels, and DMs with their IDs.
To verify a bot or integration posted a message correctly:
# Read the channel, check for the expected message
slackcli conversations read CHANNEL_ID --limit=5 --json | jq '.messages[] | select(.text | contains("expected text"))'
To send a test message and verify the round-trip:
# Send
slackcli messages send --recipient-id=CHANNEL_ID --message="integration test $(date +%s)"
# Read back
slackcli conversations read CHANNEL_ID --limit=1 --json
slackcli supports multiple workspaces. Run the auth flow for each workspace you need:
# Add first workspace
./scripts/extract-tokens https://workspace-one.slack.com
# Add second workspace
./scripts/extract-tokens https://workspace-two.slack.com
# List all authenticated workspaces
slackcli auth list
When sending messages, slackcli automatically routes to the correct workspace based on the channel ID.
~/.config/slackcli/workspaces.jsonRun nf-core bioinformatics pipelines (rnaseq, sarek, atacseq) on sequencing data. Use when analyzing RNA-seq, WGS/WES, or ATAC-seq data—either local FASTQs or public datasets from GEO/SRA. Triggers on nf-core, Nextflow, FASTQ analysis, variant calling, gene expression, differential expression, GEO reanalysis, GSE/GSM/SRR accessions, or samplesheet creation.
Simple task management using a shared TASKS.md file. Reference this when the user asks about their tasks, wants to add/complete tasks, or needs help tracking commitments.
