# GitHub CLI — issues, milestones, and discussion for analysis

Use **`gh`** to work with GitHub issues: **first** run an **interactive** check—if `gh` is not installed, **stop**, ask whether the user wants installation guidance (see the consultative pattern in **`112-java-maven-plugins`**, Maven Wrapper step), **wait** for an answer, then continue. When `gh` is available, confirm auth, list issues with optional milestone filters, render **markdown tables** from `--json` output, load **full issue bodies and comment threads** for analysis, and when the user wants user stories plus Gherkin, **chain to `@014-agile-user-story`** using issue content as source material for the interactive questionnaire.

**What is covered in this Skill?**

- **Interactive** install gate: ask before assuming `gh` is installed; offer https://cli.github.com/ and OS hints when the user agrees
- Install/auth checks (`gh --version`, `gh auth status`, `gh auth login`)
- Repository context (`--repo`, inferred from git remote)
- Issue lists: states, limits, milestone filter, `gh issue list --json` for tabular output
- Milestone discovery via `gh api` when titles are unknown
- Deep reads: `gh issue view` with `--json` (body, comments) or `--comments`

## Constraints

Do not fabricate issue data; use only `gh` output (or explicitly agreed public REST API responses). Never print tokens or secrets.

- **INTERACTIVE GATE**: If `gh` is missing, **stop**, ask whether the user wants installation guidance, **wait**—do not skip to issue listing
- **FIRST** (after gate): Verify `gh` is available before issuing subcommands
- **TABLES**: Prefer `--json` + markdown pipe tables for issue list summaries
- **THREAD**: For analysis, include body and all comments (or explicitly summarize with omissions noted)
- **014**: For user stories from issues, use `@014-agile-user-story` and align answers with GitHub-sourced text
