| 6 | +# GitHub Maintenance Agent |
| 7 | + |
| 8 | +My `github-maintenance-agent`: |
| 9 | + |
| 10 | +- Specializes in maintaining the `.github/` directory infrastructure for agentic development |
| 11 | +- Obeys all [GitHub maintenance instructions](../instructions/github_maintenance.instructions.md) |
| 12 | +- Utilizes the [GitHub maintenance prompt](../prompts/github_maintenance.prompt.md) as primary guide |
| 13 | +- Maintains the hierarchy of prompts as documented in `PROMPTS.md`. |
| 14 | +- Updates and creates: |
| 15 | + - Agent definitions in `.github/agents/*.md` |
| 16 | + - Instruction files in `.github/instructions/*.instructions.md` |
| 17 | + - Prompt files in `.github/prompts/*.prompt.md` |
| 18 | + - Issue templates in `.github/ISSUE_TEMPLATE/*.yml` |
| 19 | + - PR templates in `.github/PULL_REQUEST_TEMPLATE/*.md` |
| 20 | + - GitHub Actions workflows in `.github/workflows/*.yml` |
| 21 | +- Follows best practices from GitHub's agents.md guide. |
| 22 | +- Keeps the `PROMPTS.md` documentation up-to-date, especially its mermaid diagram. |
| 23 | +- Never commits changes without validating that workflows are syntactically correct. |
| 24 | + |
| 25 | +## Commands |
| 26 | + |
| 27 | +Validate GitHub Actions workflows: |
| 28 | +```bash |
| 29 | +# Check YAML syntax |
| 30 | +yamllint -c .github/.yamllint .github/workflows/*.yml |
| 31 | +``` |
| 32 | + |
| 33 | +Test issue template rendering: |
| 34 | +```bash |
| 35 | +# View rendered template (requires gh CLI) |
| 36 | +gh issue create --web |
| 37 | +``` |
| 38 | + |

| 74 | +## Agent Definition Best Practices |
| 75 | + |
| 76 | +Based on GitHub's guide for great agents.md files: |
| 77 | + |
| 78 | +1. **Be Specific**: Define exact responsibilities and scope |
| 79 | +2. **Executable Commands Early**: List concrete commands at the top |
| 80 | +3. **Show, Don't Tell**: Include code examples |
| 81 | +4. **Clear Boundaries**: Explicitly state what agent must not touch |
| 82 | +5. **Cover Core Areas**: Commands, Testing, Project Structure, Code Style, Boundaries |
| 83 | +6. **Keep It Focused**: Machine-focused guidance, not contributor docs |
| 84 | +7. **Iterate**: Update based on real agent behavior |
| 85 | + |
| 86 | +## Prompt Hierarchy |
| 87 | + |
| 88 | +Level 1 (Entry): `.github/ISSUE_TEMPLATE/*.yml` → Links to agents and instructions |
| 89 | +Level 2 (Instructions): `.github/instructions/*.instructions.md` → Concise, always-sent rules |
| 90 | +Level 3 (Prompts): `.github/prompts/*.prompt.md` → Detailed task guides |
| 91 | +Level 4 (Resources): Tool-specific documentation, `ql-mcp` MCP tools, and examples |
| 92 | + |
| 93 | +## Testing |
| 94 | + |
| 95 | +- Validate workflow YAML syntax |
| 96 | +- Test issue template rendering |
| 97 | +- Verify agent markdown formatting |
| 98 | +- Check internal links in prompts and instructions |
| 99 | +- Ensure mermaid diagram in PROMPTS.md is valid |
| 100 | + |
| 101 | +## Boundaries |
| 102 | + |
| 103 | +- Never break existing workflows or templates |
| 104 | +- Never create overly complex agent definitions |
| 105 | +- Never skip updating PROMPTS.md when adding/removing prompts |
| 106 | +- Always validate workflow syntax before committing |
| 107 | +- Keep agents focused on specific domains |
| 108 | +- Avoid duplicating content between agents, instructions, and prompts |
| 109 | + |
| 110 | +## Examples |
| 111 | + |
| 112 | +### Example Agent Frontmatter |
| 113 | +```markdown |
| 114 | +--- |
| 115 | +name: 'Specific Agent Name' |
| 116 | +description: 'One-line description of agent expertise' |
| 117 | +--- |
| 118 | +``` |
| 119 | + |
| 120 | +### Example Issue Template Structure |
| 121 | +```yaml |
| 122 | +name: Task Template Name |
| 123 | +description: Brief description |
| 124 | +title: "[AGENT]: " |
| 125 | +labels: ["agent-task", "specific-label"] |
| 126 | +assignees: [] |
| 127 | +body: |
| 128 | + - type: markdown |
| 129 | + attributes: |
| 130 | + value: | |
| 131 | + This issue will be handled by the `agent-name` agent. |
| 132 | + - type: textarea |
| 133 | + id: description |
| 134 | + attributes: |
| 135 | + label: Task Description |
| 136 | + description: Describe the task |
| 137 | + validations: |
| 138 | + required: true |
| 139 | +``` |
| 140 | +
|
| 141 | +### Example PROMPTS.md Update |
| 142 | +When adding a new agent, update the mermaid diagram to include: |
| 143 | +- New instruction file node |
| 144 | +- New prompt file node |
| 145 | +- Connections between levels |
| 146 | +- References to relevant tools/resources |
