-## 🤖 GitHub Automation
-
-This repository uses automated GitHub Actions workflows to keep the issue tracker tidy.
-
-### Overview
-
-| Workflow | Trigger | Purpose |
-|---|---|---|
-| `issue-dedupe.yml` | Issue opened · `workflow_dispatch` | Detects duplicate issues using Claude and labels them |
-| `backfill-dedupe.yml` | `workflow_dispatch` | Runs duplicate detection over historical issues |
-| `autoclose-labeled-issues.yml` | Daily schedule · `workflow_dispatch` | Closes issues labelled `autoclose` after N days of inactivity |
-| `remove-autoclose-label.yml` | Issue comment created | Removes the `autoclose` label when a human posts a new comment |
-
-### Required Secrets
-
-Add the following secret to the repository (**Settings → Secrets and variables → Actions**):
-
-| Secret | Description |
-|---|---|
-| `AUTHROPIC_API_KEY` | Your Anthropic API key (used by `anthropics/claude-code-action`) |
-
-`GITHUB_TOKEN` is provided automatically by GitHub Actions and does not need to be added manually.
-
-### Labels
-
-The workflows create the following labels automatically if they do not exist:
-
-| Label | Description |
-|---|---|
-| `duplicate` | Marks issues identified as duplicates |
-| `autoclose` | Marks issues that will be automatically closed after inactivity |
-
-### Running the Backfill
-
-To scan historical issues for duplicates, trigger the **Backfill Duplicate Detection** workflow manually from the **Actions** tab:
-
-- **`days_back`** (default `30`) — how many days into the past to scan
-- **`dry_run`** (default `false`) — set to `true` to preview results without modifying issues
-
-```
-Actions → Backfill Duplicate Detection → Run workflow
-```
-
-### Changing the Inactivity Threshold
-
-The default inactivity period before an `autoclose`-labelled issue is closed is **7 days**.
-
-To change it for a one-off run, trigger **Auto-close Inactive Labeled Issues** with the `inactivity_days` input.
-
-To change the default permanently, edit the `INACTIVITY_DAYS` env variable default in `.github/workflows/autoclose-labeled-issues.yml`:
-
-```yaml
-INACTIVITY_DAYS: ${{ inputs.inactivity_days || '7' }}  # ← change '7' here
-```
-
-### How Duplicate Detection Works
-
-1. When a new issue is opened, keywords from the title are used to search for the top 10 most relevant existing open issues via the GitHub Search API.
-2. The issue title, body, and candidate list are passed to **Claude** (`anthropics/claude-code-action`) with a structured prompt.
-3. Claude posts a comment on the issue (if it is highly confident it is a duplicate), including links to the original issue(s) and a brief explanation.
-4. A follow-up step reads the comment, extracts the machine-readable result, and applies the `duplicate` and `autoclose` labels.
-5. If Claude is not confident, no comment or labels are applied.
