github-issues

name	github-issues
description	Use when filing a bug, requesting a feature, creating an issue, or updating issue details. Manages issues on GitHub (and GitLab via glab) with templates, formatting, and auto-assignment.
license	MIT
allowed-tools	Read Bash(gh:*) Bash(glab:*)
model	haiku
effort	medium
compatibility	Requires a GitHub (gh) or GitLab (glab) remote; GitHub is best-supported (issue types, sub-issues, templates); a GitHub MCP server is optional and unlocks typed issue-field support
metadata	{"short-description":"Create and manage issues."}

You create, update, query, and comment on GitHub (or GitLab) issues.

Read individual rule files in rules/ for detailed requirements and examples.

Rules Overview

Rule	Impact	File
Issue title	HIGH	rules/issue-title.md
Template adherence	MEDIUM	rules/template-adherence.md
No checklists	MEDIUM	rules/no-checklists.md

CLI vs MCP Precedence

Use the CLI (gh/glab) for every operation it natively supports — it is the default interface throughout this skill. For operations with no native CLI subcommand (currently: issue fields — structured priority/effort/date/custom metadata on issues), fall back in this order:

1. GitHub MCP server tools, if such a server is connected. In Claude Code its tools are typically named mcp__github__* (list_issue_fields, issue_read, issue_write), but the name depends on how the server was registered — detect by capability, not exact ID. Never assume the server is available. This skill does not pre-approve any MCP tools — the host prompts for permission, so the user decides whether to allow them.
2. gh api against the REST/GraphQL API. Discover the schema at runtime (gh api with introspection or the documented endpoints) — do not rely on memorised queries.
3. Graceful skip: complete the rest of the operation, report which fields could not be set, and note that connecting the GitHub MCP server unlocks typed issue-field support.

Workflow

1. Determine action: create, update, query, or comment
2. Detect the remote host from git remote get-url origin (github.com → gh, gitlab.com → glab; default GitHub) and use that CLI throughout. Get owner/repo (or group/project) info. GitHub-only features — organisation issue types, issue fields, sub-issues, and .github/ISSUE_TEMPLATE/ — do not exist on GitLab: on GitLab skip the issue-type, issue-field, and sub-issue steps and use .gitlab/issue_templates/ plus description checklists instead
3. Check for issue templates in the host's conventional location: on GitHub .github/ISSUE_TEMPLATE/ or .github/; on GitLab .gitlab/issue_templates/
4. List available organisation issue types (fails for user-owned repos — expected, proceed without)
5. List available issue fields (organisation-level, inherited by repositories) via the CLI vs MCP precedence above — no native CLI subcommand exists, so use the MCP server or gh api (fails for user-owned repos — expected, proceed without)
6. For creation or update:
   • For updates: fetch the current issue first
   • When issue types are available, select the most appropriate type (e.g. Bug for defects, Feature for new functionality, Task for general work)
   • When the user specifies field values (priority, effort, dates, custom), set them via the CLI vs MCP precedence above — values must match the field's declared type (single-select option name, text, number, YYYY-MM-DD date)
   • Generate title following rules/issue-title.md
   • Generate body following template if found (see rules/template-adherence.md), otherwise use clear structured format
   • For creation: get the current authenticated user and include in assignees
   • If the user specifies a parent issue, link the created/updated issue as a sub-issue (use the issue's node ID, not its number)
7. For parent/sub-issue management:
   • To list sub-issues: get the parent issue's sub-issues
   • To add a sub-issue: pass the parent issue number and the child's node ID
   • To remove a sub-issue: unlink the child from the parent
   • To reorder sub-issues: reprioritise with after_id or before_id
   • When creating multiple related issues, prefer structuring them as a parent with sub-issues rather than flat independent issues
8. For queries:
   • Fetch a specific issue by number
   • Inspect sub-issue hierarchy on a parent issue
   • Search issues for filters, keywords, and cross-repo lookups
   • Filter by issue-field values (MCP field_filters or the API; no native CLI equivalent — degrade gracefully per the precedence above)
   • List repository issues
9. For comments:
   • Fetch issue context first when needed
   • Add the comment to the issue
10. Display a summary with issue links and what changed

Validation

• For titles: follow rules/issue-title.md
• For body with template: follow rules/template-adherence.md
• For labels: only use labels that already exist in the repository
• For fields: only set fields that already exist in the organisation or repository; never invent field names or single-select options
• For assignees: only assign valid repository collaborators
