At a glance

Update the repo-local dedupe-issue-local companion skill using closed-as-duplicate signals.

  • Works in 2 steps: Verify GitHub CLI auth → Aggregate closed-as-duplicate signals…
  • Development work in your project
  • SKILL.md covers Write surface, Inputs, Workflow and Evidence Rules, plus 1 more section
  • Runs Python scripts from its folder; calls gh, python3 and git

What it does

Update Dedupe is an agent skill from warpdotdev/oz-for-oss. Update the repo-local dedupe-issue-local companion skill using closed-as-duplicate signals. Use when maintainers repeatedly close issues as duplicates of the same canonical thread and that pattern should feed back into triage duplicate detection.

Its SKILL.md is about 930 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/aggregate_dedupe_feedback.py`).

It sits in Development. The repository describes itself as: Workflows and skills to help people and agents collaborate on open-source software with the power of Oz! The licence is MIT.

When your agent uses it

  • Development work in your project

Example prompts

  • “/update-dedupe”

Requirements

  • Python 3

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. Verify GitHub CLI auth
  2. Aggregate closed-as-duplicate signals for recently closed issues with the bundled script

What it can do on your machine

Read from SKILL.md and the folder at commit a2bb45f. 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

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • gh
    • python3
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use gh and git, which can reach the network depending on how they are called.

    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

Update Dedupe loads about 927 tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 453 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~927

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); the scripts in this folder are not scanned.

description
Update the repo-local dedupe-issue-local companion skill using closed-as-duplicate signals. Use when maintainers repeatedly close issues as duplicates of the same canonical thread and that pattern should feed back into triage duplicate detection.

Update Dedupe

Use this skill to improve .agents/skills/dedupe-issue-local/SKILL.md from real closed-as-duplicate signals. The core skill at .agents/skills/dedupe-issue/SKILL.md is the cross-repo contract and is read-only from this loop.

This loop is focused exclusively on closed-as-duplicate signals. Other maintainer signals (re-labels, re-opens, follow-up comments) are handled by the separate update-triage loop.

Write surface

This self-improvement loop may only write to:

  • .agents/skills/dedupe-issue-local/ (and SKILL.md inside it)

It must NOT touch:

  • .agents/skills/dedupe-issue/SKILL.md (the core contract)
  • .agents/skills/triage-issue-local/SKILL.md (owned by update-triage)
  • any other core skill

The self-improvement runner enforces this via a git diff check against allowed prefixes before pushing. A violation aborts the run.

Inputs

  • Optional repository override if you are not running from the target checkout.
  • Optional time window override when you need something other than the default seven-day lookback.

Workflow

  1. Verify GitHub CLI auth:
bash
gh auth status
  1. Aggregate closed-as-duplicate signals for recently closed issues with the bundled script:
bash
python3 .agents/skills/update-dedupe/scripts/aggregate_dedupe_feedback.py

By default this targets the current repo and looks back 7 days. It collects only issues GitHub itself recorded as closed with the duplicate close reason (state_reason == "duplicate") and looks up the canonical issue each was closed against via the issue timeline's marked_as_duplicate event. Ad-hoc maintainer comments that merely mention another issue are intentionally ignored to avoid false positives. The script writes structured JSON to a temporary file and prints the path.

  1. Read the generated JSON and look for repeated clusters:
  • two or more different reporters filed similar issues that maintainers closed as duplicates of the same canonical thread
  • an explicit maintainer statement that a class of issue should always be treated as a duplicate of a canonical thread

  1. Propose the smallest edit that explains the cluster. Add or update a bullet under the "Known-duplicate clusters" section of .agents/skills/dedupe-issue-local/SKILL.md summarizing the canonical thread and the distinguishing signals maintainers use to identify duplicates.

  2. Keep the core dedupe contract stable — never edit dedupe-issue/SKILL.md, never weaken the 2-candidate minimum, never change the similarity thresholds or the output shape.

Evidence Rules

  • Only encode a cluster when at least two independent closed-as-duplicate events point at the same canonical issue, or a maintainer explicitly asks for one.
  • Skip the PR when there is no repeated signal.
  • Do not weaken precision-over-recall for dedupe.

Final Checks

  • Re-read the updated dedupe-issue-local companion skill and confirm any new clusters are explicit.
  • Keep the companion concise; prefer canonical links and short distinguishing notes over long prose.
  • Commit any changes on a local branch named oz-agent/update-dedupe. Do NOT push the branch; the Python entrypoint will run a write-surface guard and push only when the guard passes.
  • If the updates warrant a PR, it will be opened from the pushed branch. Tag @captainsafia as a reviewer on that PR.
  • Validate any temporary JSON with jq before relying on it.
