What it does

Paste is an agent skill from coreyhaines31/makerskills. When you want to clean and reformat content (usually from your terminal) for pasting into Slack, Notion, Twitter/X, LinkedIn, email, GitHub, or plain text. Strips ANSI codes, box-drawing chars, terminal prompt artifacts, and applies destination-specific formatting. Default input is the clipboard (read via pbpaste); default output is both the clipboard (pbcopy) and a chat preview. Triggers on "/paste", "/paste [destination]", "clean this for X," "format for slack/notion/twitter/linkedin/email/github," "render as…

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/destinations.md` and `references/secret-patterns.md`).

It works with GitHub, LinkedIn, X (Twitter) and Notion. The repository describes itself as: AI agent skills for the personal operator's craft — decisions, research, second-brain, content rotation, scenario modeling, and meta-skills to author more. Works with Claude… The licence is MIT.

When your agent uses it

  • /paste [destination]
  • Clean this for X
  • Format for slack/notion/twitter/linkedin/email/github
  • Render as markdown

Example prompts

  • “/paste”
  • “/paste [destination]”
  • “clean this for X,”
  • “/paste”

What it can do on your machine

Read from SKILL.md and the folder at commit 1868b81. 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

Paste loads about 1.7k tokens when it runs, and up to ~3.7k if it reads all its reference files. Until then it costs about 182 tokens; SKILL.md has 789 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~182
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.7k

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.

description
When you want to clean and reformat content (usually from your terminal) for pasting into Slack, Notion, Twitter/X, LinkedIn, email, GitHub, or plain text. Strips ANSI codes, box-drawing chars, terminal prompt artifacts, and applies destination-specific formatting. Default input is the clipboard (read via `pbpaste`); default output is both the clipboard (`pbcopy`) and a chat preview. Triggers on "/paste", "/paste [destination]", "clean this for X," "format for slack/notion/twitter/linkedin/email/github," "render as markdown," "paste-ready," "strip formatting," "make this copy-pastable." Default destination is plain. Also scans for secrets (API keys, tokens, .env values) and warns before copying anything sensitive.

/paste — Clean content for any destination

Cleans terminal output (ANSI, box-drawing, prompt artifacts, etc.) and reformats per destination rules. Reads clipboard by default, writes back to clipboard + previews in chat.

Step 1 — Get the content

In order:

  1. If the user included content in the prompt (pasted, or referenced from earlier in the conversation), use that.
  2. Else, read clipboard: pbpaste
  3. If both empty, ask the user what to paste.

Step 2 — Parse destination

InvocationDestination
/pasteplain (default)
/paste plainplain
/paste slackslack
/paste notionnotion
/paste twitter or /paste xtwitter
/paste linkedin or /paste lilinkedin
/paste emailemail (plain)
/paste email rich or /paste email htmlemail (rich/HTML)
/paste github or /paste ghgithub
/paste markdown or /paste mdmarkdown render
/paste htmlrender to HTML file + open in browser

If ambiguous, ask. Per-destination rules live in references/destinations.md.

Step 3 — Scan for secrets

Before any cleaning or copying, scan against patterns in references/secret-patterns.md.

If any match:

  1. Stop. Don't copy yet.
  2. Report what was detected with the value masked (first 4 + last 4 chars only — e.g. sk-12...wxyz).
  3. Ask: "Spotted [type] in the content. Continue, redact (replace with [REDACTED]), or abort?"
  4. Default to abort if no clear answer.

Step 4 — Universal cleaning

Strip from the content:

  • ANSI escape codes — \x1b\[[0-9;]*[a-zA-Z] and related (color codes, cursor movement, screen control)
  • Box-drawing chars — ╭ ─ ╮ │ ╰ ╯ ╞ ╡ ╤ ╧ ┌ ┐ └ ┘ ├ ┤ ┬ ┴ ┼ ━ ┃ ┏ ┓ ┗ ┛ etc. Replace with simpler equivalents (-, |) or remove entirely depending on context.
  • Terminal prompt artifacts — leading $ , > , ❯ , % , # (when first non-whitespace on a line that looks like a shell prompt)
  • Carriage returns (\r) — replace with \n or delete
  • Trailing whitespace per line
  • Excess blank lines — collapse 3+ consecutive blank lines to 2

Step 5 — Apply destination rules

Read references/destinations.md and apply the relevant transform.

Step 6 — Output

DestinationOutput behavior
plain / slack / notion / twitter / linkedin / email / github(a) Show preview in a code fence in chat. (b) Copy clean version to clipboard via pbcopy.
email richRender to HTML, write to /tmp/paste-<timestamp>.html, open it in browser. Skip clipboard (the user copies from browser to preserve rich text).
markdownRender the cleaned markdown directly in chat (Claude Code renders it). Also copy raw markdown to clipboard. Offer: "Open as HTML too?" — if yes, write and open.
htmlRender to HTML, write to /tmp/paste-<timestamp>.html, open it. Skip clipboard.

After output, report a one-line summary of what was cleaned (e.g., "Stripped 12 ANSI codes, 4 box-drawing chars, 1 prompt artifact. Character count: 248 / 280 (X).").

Length warnings

Twitter and LinkedIn have practical limits. the user said "let me trim" — don't refuse or auto-truncate.

  • Twitter/X: warn if >280 chars. Note the overage.
  • LinkedIn: warn if >400 chars (comfort line, not hard limit).
  • Other destinations: no length warning.

URL handling for social destinations

If the content has URLs and destination is twitter or linkedin:

  • Surface the URLs separately (don't include them in the body)
  • Remind the user: links go in a first comment (LinkedIn) or reply (X), not the body
  • See makerskills:jab-hook and ~/.claude/memory/feedback_social_link_placement.md

Examples

/paste slack

→ Reads clipboard, strips ANSI, converts **bold** to *bold*, copies to clipboard, shows preview.

/paste twitter
[pasted error log]

→ Uses pasted content (ignores clipboard), strips everything, warns at 412/280 chars, copies, asks if the user wants to trim or pick a different destination.

/paste html
[pasted markdown table]

→ Renders table as HTML, opens in browser. the user selects + copies into Notion/email with formatting preserved.

/paste
[pasted output with sk-anthropic-key in it]

→ Stops. "Spotted what looks like an Anthropic API key: sk-an...3kf9. Continue, redact, or abort?"

Composes with

  • jab-hook — clean output for pasting into Typefully drafts when the MCP path doesn't fit; also enforces the link-placement rule for X/LinkedIn destinations
  • social-fetch — clean a fetched post before quoting it in a draft or newsletter
  • second-brain — paste output can be captured cleanly into raw/note-<slug>.md for future compilation
  • watch-video — transcript / summary output often flows through paste for platform-specific reformatting

Notes on quality

  • Secret detection runs first, always. Before any formatting or destination logic, paste scans for sk-*, AKIA*, xoxb-*, JWT-shaped strings, and long-hex tokens. Prompts before proceeding on any hit. Better to false-positive occasionally than to leak a real key.
  • Destination-aware transforms, not one-size-fits-all. Slack wants *bold*; LinkedIn wants unicode-styled bold; email wants HTML. Same input, 9 different valid outputs. The destination flag is not optional.
  • ANSI codes get stripped for every destination. Terminal escapes (\033[31m etc.) render as garbage everywhere except the source terminal.
  • Character limits are enforced, not warnings. X at 280, LinkedIn at 3000, Twitter at 25000 — paste refuses to copy over-limit output and offers a trim strategy.
  • Links go in first comments for social destinations — not the body. Enforced when destination is twitter or linkedin. Documented in ~/.claude/memory/feedback_social_link_placement.md.
  • HTML destination opens in a browser tab, not the clipboard. Formatted tables + code blocks need a rendered surface to select-and-copy from with formatting preserved. Copying raw HTML to the clipboard produces garbage in Notion/email.

When you want to clean and reformat content (usually from your terminal) for pasting into Slack, Notion, Twitter/X, LinkedIn, email, GitHub, or plain text.

When should I use Paste?

Paste fits situations like: /paste [destination]; clean this for X; format for slack/notion/twitter/linkedin/email/github; render as markdown.

How do I install Paste in Claude Code?

Run `npx skills add coreyhaines31/makerskills --skill paste -a claude-code`. Or copy the skill folder (skills/paste in coreyhaines31/makerskills) into .claude/skills/paste in your project. Claude Code loads it when a task matches its description.

How do I install Paste in Codex?

Run `npx skills add coreyhaines31/makerskills --skill paste -a codex`. Or copy the skill folder (skills/paste in coreyhaines31/makerskills) into .agents/skills/paste in your project. Codex loads it when a task matches its description.

Can I use Paste in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add coreyhaines31/makerskills --skill paste -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/paste, .gemini/skills/paste, .github/skills/paste and .opencode/skills/paste in your project.

What does Paste need to run?

SKILL.md names no scripts, command-line tools or credentials: Paste is instructions for the agent only.

Does Paste access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Paste safe to install?

Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.

What licence does Paste use?

Paste is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Paste use?

About 1.7k tokens (SKILL.md is roughly 6.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2k tokens, read only when the agent opens those files.

What are the alternatives to Paste?

Skills that share tags, products or a category with Paste: Social Preview (thatrebeccarae/claude-marketing, 162 stars), Composio (ComposioHQ/composio, 30k stars), Changelog Social Recap (FlorianBruniaux/claude-code-ultimate-guide, 6.1k stars) and Connect Apps with Composio (ComposioHQ/awesome-claude-skills, 77k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Paste?
