+## Inputs
+
+| Input | Default |
+|---|---|
+| `organization` | `my-org` |
+| `inactive_days` | `365` |
+| `exempt_repos` | _(none)_ |
+| `exempt_topics` | _(none)_ |
+| `activity_method` | `pushed` |
+
+Use the workflow dispatch inputs if provided; otherwise fall back to the defaults above.
+
+## Instructions
+
+### 1. Enumerate repositories
+
+List **all** repositories in the `organization`. Exclude any repo that is:
+
+- **Archived** — skip it entirely.
+- **Listed in `exempt_repos`** — compare repo names (case-insensitive) against the comma-separated list.
+- **Tagged with an exempt topic** — if the repo has any topic that appears in the comma-separated `exempt_topics` list, skip it.
+
+### 2. Determine last activity date
+
+For each remaining repo, determine the **last activity date** based on `activity_method`:
+
+- **`pushed`** — use the repository's `pushed_at` timestamp (this is the default and most efficient method).
+- **`default_branch_updated`** — fetch the most recent commit on the repo's default branch and use that commit's `committer.date`.
+
+### 3. Identify stale repos
+
+Calculate the number of days between the last activity date and **today**. If the number of days exceeds `inactive_days`, mark the repo as **stale**.
+
+### 4. Generate report
+
+Build a **Markdown report** with a summary and a table:
+
+> **Stale Repository Report — \<date\>**
+> Found **N** repositories with no activity in the last **inactive_days** days.
+
+| Repository | Days Inactive | Last Push Date | Visibility |
+|---|---|---|---|
+| [owner/repo](https://github.com/owner/repo) | 420 | 2024-01-15 | public |
+
+Sort the table by **Days Inactive** descending (most stale first).
+
+If there are **no stale repos**, still create the issue but note that all repositories are active.
+
+### 5. Create or update issue
+
+Search for an existing **open** issue in the `organization/.github` repo (or the repo this workflow runs in) with the label `stale-repos` and a title starting with `[Stale Repos]`.
+
+- If an **existing open issue** is found, **update its body** with the new report.
+- If **no open issue** exists, **create a new issue** with:
+  - Title: `[Stale Repos] Inactive Repository Report — <date>`
+  - Label: `stale-repos`
+  - Body: the full Markdown report from step 4.
