What it does

Reply From Superhuman is an agent skill from superset-sh/superset. Draft a reply, a follow-up, or a new email in Superhuman in the user's own voice — read the whole thread first, reuse an existing draft instead of adding a second one, keep the right people on the thread, and leave sending to the user unless they asked for it. Use when the user says reply to, answer, follow up with, draft an email to, or send, or when a triage turned up threads that need a response.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Superset is an agentic IDE to orchestrate 100+ coding agents in parallel. Run any agent with your own subscription.

When your agent uses it

  • The user says reply to
  • Draft an email to
  • A triage turned up threads that need a response

Example prompts

  • “/reply-from-superhuman”

Requirements

  • Pre-approved tools (allowed-tools): mcp__superhuman__list_accounts, mcp__superhuman__list_threads, mcp__superhuman__get_thread, mcp__superhuman__get_message, mcp__superhuman__get_attachment, mcp__superhuman__list_drafts, mcp__superhuman__get_draft, mcp__superhuman__get_draft_send_status, mcp__superhuman__create_or_update_draft, mcp__superhuman__discard_draft, mcp__superhuman__list_snippets, mcp__superhuman__get_snippet, mcp__superhuman__undo_send

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Read the thread end to end
  2. Look for a draft before writing one
  3. Draft with instructions, not prose
  4. Stop at the draft

What it can do on your machine

Read from SKILL.md and the folder at commit 4ec5b6e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • mcp__superhuman__list_accounts
    • mcp__superhuman__list_threads
    • mcp__superhuman__get_thread
    • mcp__superhuman__get_message
    • mcp__superhuman__get_attachment
    • mcp__superhuman__list_drafts
    • mcp__superhuman__get_draft
    • mcp__superhuman__get_draft_send_status
    • mcp__superhuman__create_or_update_draft
    • mcp__superhuman__discard_draft

    …and 3 more on the same allowed-tools line.

    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

Reply From Superhuman loads about 1.1k tokens when it runs. Until then it costs about 106 tokens; SKILL.md has 587 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~106
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 587 words (~1,098 tokens).

“A draft in Superhuman is the user's to send; the job is to make it the one they would have written. Read the whole thread, draft once, and stop at the draft.”
