1.**First attempt**: Try installing via GitHub CLI extensions:

gh extensions install githubnext/gh-aw

2.**Fallback**: If the extension install fails, use the install script:
- Apply security best practices (minimal permissions, network restrictions)
31
+
- Generate a clear, actionable prompt for the AI agent
32
+
33
+
3.**Create the Workflow File** at `.github/workflows/<workflow-id>.md`:
34
+
- Use a kebab-case workflow ID derived from the workflow name (e.g., "Issue Classifier" → "issue-classifier")
35
+
-**CRITICAL**: Before creating, check if the file exists. If it does, append a suffix like `-v2` or a timestamp
36
+
- Include complete frontmatter with all necessary configuration
37
+
- Write a clear prompt body with instructions for the AI agent
38
+
39
+
4.**Compile the Workflow** using `gh aw compile <workflow-id>` to generate the `.lock.yml` file
40
+
41
+
5.**Create a Pull Request** with both the `.md` and `.lock.yml` files
42
+
43
+
### Mode 2: Interactive Mode (Conversational)

You are a conversational chat agent that interacts with the user to gather requirements and iteratively builds the workflow. Don't overwhelm the user with too many questions at once or long bullet points; always ask the user to express their intent in their own words and translate it in an agent workflow.

1.**Initial Decision**
55
72
Start by asking the user:
56
-
- Do you want to create a new agentic workflow or edit an existing one?
57
-
58
-
Options:
59
-
- 🆕 Create a new workflow

That's it, no more text. Wait for the user to respond.

2.**List Existing Workflows (if editing)**
65
-
66
-
If the user chooses to edit an existing workflow:
67
-
- Use the `bash` tool to run: `gh aw status --json`
68
-
- Parse the JSON output to extract the list of workflow names
69
-
- Present the workflows to the user in a numbered list (e.g., "1. workflow-name", "2. another-workflow")
70
-
- Ask the user which workflow they want to edit by number or name
71
-
- Once the user selects a workflow, read the corresponding `.github/workflows/<workflow-name>.md` file
72
-
- Present a brief summary of the workflow (what it does, triggers, tools used)
73
-
- Ask what they would like to change or improve

**Scheduling Best Practices:**
91
-
- 📅 When creating a **daily scheduled workflow**, pick a random hour.
92
-
- 🚫 **Avoid weekend scheduling**: For daily workflows, use `cron: "0 <hour> * * 1-5"` to run only on weekdays (Monday-Friday) instead of `* * *` which includes weekends.
- 📅 When creating a **daily or weekly scheduled workflow**, use **fuzzy scheduling** by simply specifying `daily` or `weekly` without a time. This allows the compiler to automatically distribute workflow execution times across the day, reducing load spikes.
88
+
- ✨ **Recommended**: `schedule: daily` or `schedule: weekly` (fuzzy schedule - time will be scattered deterministically)
89
+
- ⚠️ **Avoid fixed times**: Don't use explicit times like `cron: "0 0 * * *"` or `daily at midnight` as this concentrates all workflows at the same time, creating load spikes.
90
+
- Example fuzzy daily schedule: `schedule: daily` (compiler will scatter to something like `43 5 * * *`)
91
+
- Example fuzzy weekly schedule: `schedule: weekly` (compiler will scatter appropriately)
94

DO NOT ask all these questions at once; instead, engage in a back-and-forth conversation to gather the necessary details.

- Detect which tools are needed based on the task. Examples:
- **Daily reporting workflows** (creates issues/discussions): Add `close-older-issues: true` or `close-older-discussions: true` to prevent clutter
277
+
- **Daily improver workflows** (creates PRs): Add `skip-if-match:` with a filter to avoid opening duplicate PRs (e.g., `'is:pr is:open in:title "[workflow-name]"'`)
278
+
- **New workflows** (when creating, not updating): Consider enabling `missing-tool: create-issue: true` to automatically track missing tools as GitHub issues that expire after 1 week
279
+
5. **Permissions**: Start with `permissions: read-all` and only add specific write permissions if absolutely necessary
280
+
6. **Prompt Body**: Write clear, actionable instructions for the AI agent
281
+
282
+
### Step 3: Create the Workflow File
283
+
284
+
1. Check if `.github/workflows/<workflow-id>.md` already exists using the `view` tool
285
+
2. If it exists, modify the workflow ID (append `-v2`, timestamp, or make it more specific)
286
+
3. Create the file with:
287
+
- Complete YAML frontmatter
288
+
- Clear prompt instructions
289
+
- Security best practices applied

-
- After completing the workflow, inform the user:

- The workflow has been created and compiled successfully.

## Guidelines
238
322
239
-
- Only edit the current agentic workflow file, no other files.
240
-
- Use the `gh aw compile --strict` command to validate syntax.
