What it does
Slack Message Formatter is an agent skill from davepoon/buildwithclaude. Format messages for Slack with pixel-perfect accuracy. Converts Markdown to rich HTML (for copy-paste into Slack) or Slack mrkdwn (for API/webhook). Use when the user asks to write a Slack message, announcement, or notification, format something "for Slack", preview how content looks in Slack, or send a message via Slack webhook. Also trigger when user mentions Slack formatting, mrkdwn, or wants to share Markdown content in Slack channels.
Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs, covering Linting and formatting, Webhooks and Design to code. It works with Slack. The repository describes itself as: A single hub to find Claude Skills, Agents, Commands, Hooks, Plugins, and Marketplace collections to extend Claude Code, Claude Desktop, Agent SDK and OpenClaw. The licence is MIT.
When your agent uses it
- The user asks to write a Slack message
- Format something for Slack
- Preview how content looks in Slack
- Send a message via Slack webhook
Example prompts
- “for Slack”
- “/slack-message-formatter”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Copy-paste — Rich HTML that preserves formatting when pasted into Slack's compose box
- API/Webhook — Slack mrkdwn syntax for bots, automation, and CI/CD
What it can do on your machine
Read from SKILL.md and the folder at commit 10bfc43. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Slack Message Formatter loads about 988 tokens when it runs. Until then it costs about 117 tokens; SKILL.md has 406 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Slack Message Formatter
Format messages for Slack with pixel-perfect accuracy. Converts Markdown to Slack-compatible output with two delivery paths:
- Copy-paste — Rich HTML that preserves formatting when pasted into Slack's compose box
- API/Webhook — Slack mrkdwn syntax for bots, automation, and CI/CD
When to Use This Skill
- User asks to write a Slack message, announcement, or notification
- User asks to format something "for Slack"
- User wants to preview how a message will look in Slack
- User wants to send a message via Slack webhook
- User has Markdown content they want to share in Slack
What This Skill Does
- Generates content in Markdown — Claude writes the message in standard Markdown, its native format
- Converts to Rich HTML — Transforms Markdown into rich HTML that preserves formatting when pasted into Slack's compose box
- Converts to Slack mrkdwn — Transforms Markdown into Slack's proprietary mrkdwn syntax for API/webhook delivery
- Generates a Slack-themed preview — Creates an HTML preview page styled like the Slack UI and opens it in the browser
- Copies to clipboard — Automatically copies the rich HTML to the system clipboard for one-step paste into Slack
How to Use
Basic Usage
Write a Slack message announcing our Q2 product launchFormat this for Slack: We shipped 3 new features this week...Create a Slack announcement for the engineering team about the new CI pipelineWebhook/API Delivery
Send a deploy notification to Slack via webhookFormatting Features
The converter handles all Markdown features and translates them correctly for Slack:
- Bold, italic, strikethrough, inline code
- Links and headings (converted to bold in Slack)
- Tables (rich HTML tables for paste, code blocks for API)
- Task lists with emoji checkboxes
- Nested lists and blockquotes
- Code blocks with syntax highlighting
- Slack mentions (
<@U012AB3CD>,<!here>,<!channel>) - 150+ emoji shortcodes converted to Unicode

Example
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 passingConfiguration
| Env Variable | Default | Description |
|---|---|---|
SLACK_FORMATTER_CLIPBOARD | true | Set to false to disable auto-clipboard copy |
SLACK_FORMATTER_PREVIEW_DIR | /tmp/slack-formatter | Directory for preview HTML files |
CCH_SLA_WEBHOOK | (none) | Slack webhook URL for sending messages |
Tips
- Always let the converter handle the Markdown-to-Slack translation; never write mrkdwn or HTML by hand
- Slack mentions (
<@U...>,<#C...>,<!here>) can be included directly in the Markdown - Tables work beautifully via the copy-paste path; for API delivery they become code blocks (Slack has no table syntax)
- Preview files are timestamped so you can revisit them from conversation history
