Add assign-milestone safe output for assigning issues to milestones

[Copilot]

Implementation Complete: Assign-Milestone Safe Output

This PR adds a new "assign-milestone" safe output type that allows AI agents to assign issues to milestones with allowlist-based security.

Recent Changes

• Fixed noop script bundling issue (commit addresses comment #3550893883)
  • Moved noop.cjs from js.go (unbundled scripts) to scripts.go (bundled scripts)
  • Added proper bundler configuration with getNoOpScript() function
  • Removed duplicate getNoOpScript() function from noop.go
  • Added assign_milestone to expected tools list in tests
  • All 1040 JavaScript tests passing ✅
  • All Go unit tests passing ✅
  • All 81 workflows compiled successfully with 0 errors ✅

Configuration

The allowed field is mandatory and accepts either a string or array of milestone names/IDs:

safe-outputs:
  assign-milestone:
    allowed: ["v1.0", "v1.1", "v2.0"]  # Milestone titles or numeric IDs
    max: 3                              # Optional: limit assignments per run
    target: "*"                         # Optional: allow any issue via item_number
    target-repo: "org/other-repo"      # Optional: cross-repo support

JSONL Output Format

AI agents can now use the assign_milestone tool in their MCP server:

{"type": "assign_milestone", "milestone": "v1.0"}
{"type": "assign_milestone", "milestone": "v1.1", "item_number": 42}
{"type": "assign_milestone", "milestone": 5}

Dev Workflow Example

The dev.md workflow demonstrates the functionality:

1. Lists open issues in the repository
2. Selects a random issue
3. Assigns it to the "v0.Later" milestone using the assign_milestone tool

Configuration:

safe-outputs:
  assign-milestone:
    allowed: ["v0.Later"]
    target: "*"
    max: 1

Technical Details - Noop Script Fix

The issue was that noop.cjs has a require("./load_agent_output.cjs") statement, which means it needs to be bundled. However, it was embedded in js.go (for scripts that don't need bundling) instead of scripts.go (for scripts that need bundling).

Changes made:

1. Removed //go:embed js/noop.cjs from js.go
2. Added //go:embed js/noop.cjs to scripts.go with noopScriptSource variable
3. Added bundling variables: noopScript and noopScriptOnce
4. Added getNoOpScript() function with proper bundler logic
5. Removed duplicate function from noop.go
6. Updated tests to include assign_milestone in expected tools

This ensures that when noop.cjs is loaded, all its require() statements are properly inlined by the bundler, preventing the "module not found" error in GitHub Actions.

Key Features

1. Allowlist-Based Security - Mandatory allowed field with milestone names/IDs
2. Flexible Configuration - Supports string or array formats
3. Automatic Resolution - Converts milestone titles to IDs via GitHub API
4. Case-Insensitive Matching - User-friendly milestone name matching
5. Target Configuration - Supports triggering issue, explicit numbers, or wildcard
6. Cross-Repository Support - Can operate on issues in other repos
7. Staged Mode - Preview changes without making API calls
8. Comprehensive Validation - Type checking, allowlist enforcement, API validation
9. MCP Tool Integration - Available as a tool in the safe outputs MCP server

Test Results

• JavaScript: 1040/1040 tests passing ✅
• Go: All unit tests passing ✅
• Workflows: 81 workflows compiled successfully with 0 errors ✅
• Code quality: Formatted and linted successfully ✅

The feature is complete, tested, and ready for merge! 🎉

Original prompt

Add a "add-milestone" safe output that allows to add an issues to a milestone.

• there is a mandatory allowed list of milestones

• infer issue number from context similarly to other issue related safe outputs

• front matter allows a string (one allowed milestone), string[] (multiple allowed milestones or object with "allowed" field

  allowed: ...

Completed the rename from add-milestone to assign-milestone in commit aadea75.

All files, code references, schemas, tests, and workflows have been updated. The implementation is fully functional with all 1009 tests passing and 80 workflows compiled successfully.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/user
  • Triggering command: gh api user --jq .login (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot update dev.md to assign a random issue to the "ultimate" milestone on workflow dispatch

Updated dev.md to assign a random issue to the "ultimate" milestone on workflow_dispatch in commit 675f964. The workflow now:

1. Lists open issues using the GitHub tool
2. Selects a random issue
3. Assigns it to the "ultimate" milestone using the assign_milestone safe output

Configuration added:

safe-outputs:
  assign-milestone:
    allowed: ["ultimate"]
    target: "*"
    max: 1

[pelikhan]

@copilot make sure assign-milestone tool is added to tools.json and properly configured.

The run https://github.com/githubnext/gh-aw/actions/runs/19474205828/job/55729585359#step:29:1 failed because the tool was missing.

⚠️ Dev Hawk Report - Failure Analysis

Workflow Run: #3000

• Status: failure
• Commit: eb9cb4f
• Duration: ~2 minutes 17 seconds

Root Cause Analysis

The noop safe output job is failing due to a missing JavaScript module dependency. The job is attempting to load load_agent_output.cjs using a relative path, but the file is not available in the working directory.

Error Details

Error: Cannot find module '/home/runner/work/gh-aw/gh-aw/load_agent_output.cjs'
Require stack:
- /home/runner/work/_actions/actions/github-script/ed597411d8f924073f98dfc5c65a23a2325f34cd/dist/index.js
    at Module._resolveFilename (node:internal/modules/cjs/loader:1420:15)

Key Problem: The script uses:

const { loadAgentOutput } = require("./load_agent_output.cjs");

This relative require expects load_agent_output.cjs to be in the current working directory (/home/runner/work/gh-aw/gh-aw/), but it's not present.

Failure Category

Configuration Error - Missing module dependency/incorrect module resolution path

Recommended Actions

• Add checkout step - Ensure the repository is checked out before the noop job runs so that load_agent_output.cjs is available:

  - uses: actions/checkout@v4

• Use bundled script - If load_agent_output.cjs is meant to be bundled/embedded in the compiled workflow, verify the bundling process is working correctly

• Fix module path - If the module is provided externally, update the require path to the correct location

Investigation Notes

This appears to be a recent issue introduced with the noop safe output implementation. The job successfully downloads the agent_output.json artifact but fails when trying to process it. The noop job doesn't include a checkout step, which means the repository code (including load_agent_output.cjs) is not available in the runner's filesystem.

Similar jobs (like assign_milestone) likely have the same pattern and may need the same fix if they use relative requires without checking out the repository first.

@copilot make sure the bundler is applied to the no-op javascript safe output.

See error in https://github.com/githubnext/gh-aw/actions/runs/19490895665/job/55782824497#step:4:1

Fixed in commit bb750df. The noop script now has proper bundler configuration in scripts.go, which inlines the load_agent_output.cjs require statement. All tests pass (1040 JavaScript tests, all Go tests) and 81 workflows compile successfully.
