dedupe-issue

dedupe-issue is a skill for Claude Code, Codex from warpdotdev/oz-for-oss. It costs 46 tokens per session (839 once invoked), scanned A, original, MIT.

A GitHub issue-triage helper that compares a new issue with existing repository issues to find likely duplicates.

In plain words
What is it for?
Use it during GitHub issue triage to review open issues, compare their titles and descriptions, and surface possible duplicates.
Why use it?
It reduces manual searching when deciding whether someone has already reported the same problem.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dedupe-issue scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Detect duplicate issues

Compare a newly filed GitHub issue against existing issues in the repository and identify likely duplicates by similarity of title and description.

Inputs

Expect the prompt to include:

  • the incoming issue's number, title, and description
  • the repository owner/name, so you can search issues yourself via the GitHub API or gh api --paginate

Process

  1. Enumerate comparison candidates yourself. Fetch all open issues in the repository with pagination, excluding pull requests and the incoming issue itself. Use the GitHub API directly or gh api --paginate; do not rely on a preselected candidate list from the triage prompt and do not cap the search to the newest issues.
  2. Fetch closed issues only when they were closed within the last 7 days or when repository-specific guidance names a known canonical duplicate. Older closed issues should generally not be treated as duplicates because they may already be resolved.
  3. Normalize the incoming issue's title and description by lowercasing, stripping leading/trailing whitespace, and collapsing runs of whitespace into single spaces.
  4. For each candidate issue in the comparison set: a. Compute title similarity: compare the incoming title to the candidate title. Consider them title-similar when they share the same core noun phrases or intent after stripping common prefixes like "bug:", "feature:", "[request]", emoji, and markdown formatting. b. Compute description similarity: compare the key symptoms, error messages, reproduction steps, and requested behavior between the incoming and candidate descriptions. Ignore boilerplate template sections (e.g., "## Environment", "## Steps to Reproduce" headers with empty content) that do not carry diagnostic signal. c. A candidate is a likely duplicate when both of the following hold:
    • The titles convey the same problem, feature request, or question (not merely sharing a common keyword).
    • The descriptions overlap on at least one substantive detail: a shared error message, the same failing behavior, the same requested capability, or an equivalent reproduction scenario.
  5. Rank candidates by overall similarity (title weight ≈ 40%, description weight ≈ 60%) and select the top matches.
  6. Only flag an issue as a duplicate when 2 or more existing issues are identified as likely duplicates. A single weak match is not sufficient — the evidence must be corroborated across multiple existing issues to reduce false positives.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
