Format messages for Slack with pixel-perfect accuracy. Converts Markdown to Slack-compatible output with two delivery paths:
Write a Slack message announcing our Q2 product launch
Format this for Slack: We shipped 3 new features this week...
Create a Slack announcement for the engineering team about the new CI pipeline
Send a deploy notification to Slack via webhook
The converter handles all Markdown features and translates them correctly for Slack:
<@U012AB3CD>, <!here>, <!channel>)User: "Write a Slack message announcing our new feature"
Output (opened as a Slack-themed preview in the browser + copied to clipboard):
The preview shows a pixel-perfect Slack UI rendering. The user pastes directly into Slack with Cmd+V / Ctrl+V and the formatting is preserved.
User: "Send a deploy notification to our #deploys channel via webhook"
Output (sent via mrkdwn to the configured webhook):
*:rocket: Deploy Successful*
*Service:* payment-api
*Version:* v2.5.1
*Environment:* production
*Duration:* 47s
:white_check_mark: All health checks passing

Pull the ads a competitor is running right now on Meta (Facebook/Instagram) and Google, then extract the hooks, offers, CTAs and landing pages worth modelling. Use when writing ad copy, planning creative tests, choosing a landing page angle, or when the user asks "what is X advertising", "what ads does X run", "find competitor ad hooks". Reads live Ad Library and Ads Transparency data through the Tracetify MCP; falls back to a manual Ad Library walkthrough when the connector is absent.

Teaches when to recall from long-term memory before acting and when to save durable decisions, corrections and failures afterwards. Use when a memory tool or MCP memory server is connected but the agent is not using it consistently, when the user complains that the assistant forgets preferences, conventions or past decisions between sessions, or when setting up persistent memory for a project. Works with any memory backend: a folder of Markdown files, a local MCP server, or a managed service.

Checks which private files (.env, keys, secrets) Claude Code and its subagents reached in this project, whether a value came into an agent's context, and which key to change, by running the open source agentwhy CLI over the session records Claude Code already keeps on disk. Use when the user asks whether the agent or a subagent read their .env or other secrets, which private files a session touched, whether a key leaked into the conversation, or which key to rotate. Runs locally and never prints a secret value.
