+name: create-issue
+description: Creates GitHub issues for the package repository. Use when asked to create, file, or open a GitHub issue, or when planning new features or functions that need to be tracked.
+compatibility: Requires the `gh` CLI and an authenticated GitHub session.
+---
+
+# Create a GitHub issue
+
+Use `gh api graphql` with the `createIssue` mutation to create issues. This sets the issue type in a single step. Write the body to a temp file first, then pass it via `$(cat ...)`.
+
+## Looking up IDs
+
+The hardcoded IDs below are correct for this repo as of 2026-03-02. If they ever change, or if you're working in a fork or a repo other than "wranglezone/datawrap", re-run these queries to get fresh values (updating owner and name if necessary).
+
+```bash
+# Repository node ID
+gh api graphql -f query='{ repository(owner: "wranglezone", name: "datawrap") { id } }'
+
+# Available issue type IDs
+gh api graphql -f query='{ repository(owner: "wranglezone", name: "datawrap") { issueTypes(first: 20) { nodes { id name } } } }'
+```
+
+## Issue type
+
+Choose the type that best fits the issue:
+
+| Type | ID | Use for |
+|---|---|---|
+| Feature | `IT_kwDODjbzj84BwJRW` | New exported functions or capabilities |
+| Bug | `IT_kwDODjbzj84BwJRV` | Something broken or incorrect |
+| Documentation | `IT_kwDODjbzj84BwprI` | Docs-only changes |
+| Task | `IT_kwDODjbzj84BwJRU` | Maintenance, refactoring, chores |
+
+## Issue title
+
+Titles use conventional commit prefixes:
+
+- `feat: my_function()` — new exported function or feature
+- `fix: short description` — bug fix
+- `docs: short description` — documentation
+- `chore: short description` — maintenance or task
+
+## Issue body structure
+
+Which sections to include depends on the issue type:
+
+| Section | Feature | Bug | Documentation | Task |
+|---|---|---|---|---|
+| `## Summary` | ✓ | ✓ | ✓ | ✓ |
+| `## Details` | optional | optional | optional | optional |
+| `## Proposed signature` | ✓ | — | — | — |
+| `## Behavior` | ✓ | ✓ | — | — |
+| `## References` | optional | optional | optional | optional |
+
+### `## Summary` (all types)
+
+A single user story sentence (no other content in this section):
+
+```markdown
+> As a [role], in order to [goal], I would like to [feature].
+```
+
+Example:
+
+```markdown
+## Summary
+
+> As a data wrangler, in order to share information about my dataset, I would like to create a simple data dictionary based on my dataset.
+```
+
+### `## Details` (optional, all types)
+
+For information that's important to capture but doesn't fit naturally into any other section. Use sparingly — if the content belongs in `## Behavior`, `## Proposed signature`, or `## References`, put it there instead.
+
+### `## Proposed signature` (Feature only)
+
+The proposed R function signature, arguments table, and return value description:
+
+````markdown
+## Proposed signature
+
+```r
+function_name(arg1, arg2)
+```
+
+**Arguments**
+
+- `arg1` (`TYPE`) — Description.
+- `arg2` (`TYPE`) — Description.
+
+**Returns** a `TYPE` with description.
+````
+
+### `## Behavior` (Feature and Bug)
+
+- **Feature**: bullet points describing expected behavior, edge cases, and any internal helpers to implement as part of this issue.
+- **Bug**: describe the current (broken) behavior, the expected behavior, and steps to reproduce if known.
+
+### `## References` (optional, all types)
+
+Only include when there are specific reference implementations, external URLs, or related code to link to. Omit it entirely when there are none.
+
+## Creating the issue
+
+```bash
+gh api graphql \
+  -f query='mutation($repoId:ID!, $title:String!, $body:String!, $typeId:ID!) {
+    createIssue(input:{repositoryId:$repoId, title:$title, body:$body, issueTypeId:$typeId}) {
+      issue { url }
+    }
+  }' \
+  -f repoId="R_kgDORb_Ktg" \
+  -f title="feat: my_function()" \
+  -f body="$(cat /tmp/issue_body.md)" \
+  -f typeId="IT_kwDODjbzj84BwJRW"
