What it does

Duplicate Sweep is an agent skill from superset-sh/superset. Find and merge duplicate Linear issues — group reports of the same underlying bug, pick the survivor, and move the evidence across. Use when the backlog has grown noisy, someone asks whether an issue is already reported, or you are cleaning up before planning.

Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Linear. 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 backlog has grown noisy
  • Someone asks whether an issue is already reported
  • You are cleaning up before planning

Example prompts

  • “/duplicate-sweep”

Requirements

  • Pre-approved tools (allowed-tools): mcp__linear__*

Workflow steps

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

  1. Search the way reporters write, not the way you think
  2. Same symptom is not the same bug
  3. Pick the survivor deliberately
  4. Confirm the groups before you touch anything
  5. Move what matters before closing
  6. Report

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__linear__*

    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

Duplicate Sweep loads about 841 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 500 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~69
When it runs · the whole SKILL.md, loaded when a task matches
~841

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 500 words (~841 tokens).

“Two issues for one bug means two people investigate it and neither sees the other's findings. The goal is one issue per underlying problem, holding everything anyone learned.”
