Paste a Slack thread, Linear issue or GitHub PR link and Claude gets its contents as context before it answers
Seven Claude Code mods (function-hook plugins) that wire your terminal into Slack, Linear, GitHub and Datadog through the Composio CLI.
Demo: video/out.mp4. The video is built with fframes; its source is in video/.
/reviews lists your open PRs waiting on reviewers, with a Slack nudge button per reviewer./snippet drafts your daily Slack update from the last 24h of Linear + GitHub and posts it on one press./standup pane, looks up failing-test errors in Datadog ("seen before"), and sets your Slack status while the agent is busy.composio CLI call into a status-line sparkline (/pulse for details) and blocks re-linking a toolkit that's already connected./plugin marketplace add tridha643/claude-composio-mods
/plugin install ticket-band@claude-composio-modsInstall whichever mods you want the same way. To hack on them instead, clone the repo and run claude --plugin-dir plugins/<mod>.
