Summary

This PR migrates the Datadog API Claude plugin from a custom TypeScript/Node.js implementation to using the existing pup CLI tool. This is a major architectural simplification that removes ~19,000 lines of custom code while maintaining all functionality.

Motivation

The plugin was maintaining a custom TypeScript implementation that duplicated functionality already provided by the pup CLI tool. By migrating to use pup, we:

  • Eliminate duplicate code and maintenance burden
  • Leverage pup's mature OAuth2 implementation with OS keychain support
  • Benefit from pup's comprehensive API coverage (28 command groups, 33+ API domains)
  • Provide faster execution via a single Go binary
  • Maintain consistent tooling across both projects

Changes

Removed (~19,000 lines)

  • ❌ TypeScript/Node.js implementation (src/, dist/, tests/)
  • ❌ TypeScript configuration (tsconfig.json, eslint.config.mjs, jest.config.js)
  • ❌ npm dependencies (Datadog API client, build tools, testing frameworks)

Updated

  • ✏️ package.json (package.json:4)

    • Simplified to metadata-only
    • Version bumped to 2.0.0 (breaking change)
    • Removed all scripts and dependencies
  • ✏️ skills/code-generation/SKILL.md (skills/code-generation/SKILL.md:1-552)

    • Completely rewritten to show two approaches:
      1. Immediate execution using pup CLI
      2. Code generation for application integration
    • Added comprehensive examples for Python, TypeScript, Java, Go, and Rust
    • Includes pup command patterns and API client usage
    • All references use pup (not ./pup or ../pup/pup)
  • ✏️ README.md (README.md:1-467)

    • Rewritten to focus on pup integration
    • Removed build/install/development sections
    • Added pup command reference and examples
    • Updated authentication section to reference pup
    • Simplified architecture section
    • Standardized all CLI references to just pup
  • ✏️ AGENTS.md (AGENTS.md:689-711, 855-878)

    • Updated architecture section to describe pup integration
    • Updated project structure to reflect new organization
    • Added reference to pup as external dependency
    • Standardized references to just pup

Preserved

  • ✅ All 46 specialized agent files (unchanged)
  • ✅ Agent-based architecture (unchanged)
  • ✅ Natural language interaction patterns (unchanged)
  • ✅ Code generation capabilities (now via examples, not code)

Breaking Changes

⚠️ This is a breaking change (major version bump to 2.0.0)

Before:

npm install
npm run build
node dist/index.js metrics query --query="..."

After:

# Install pup (see https://github.com/DataDog/pup#installation)
pup auth login
pup metrics query --query="..."

Users must now:

  1. Have pup CLI installed and available in PATH
  2. Authenticate via pup (pup auth login or DD_API_KEY/DD_APP_KEY)
  3. Use natural language with Claude (agents execute pup commands automatically)

Testing

Manual testing performed:

  • ✅ Verified all documentation builds correctly
  • ✅ Confirmed CLAUDE.md symlink still works
  • ✅ Reviewed all agent files remain unchanged
  • ✅ Verified package.json is valid JSON
  • ✅ Confirmed all pup references are consistent (just pup, not ./pup or ../pup/pup)

Integration testing requires:

  • pup CLI to be installed and functional
  • Natural language interaction with Claude using the updated agents
  • Code generation examples for each supported language

Migration Guide for Users

For Direct Users

If you were using the plugin directly with node dist/index.js:

  1. Install pup: See pup installation guide
  2. Authenticate: pup auth login
  3. Replace node dist/index.js <command> with pup <command>

For Claude Users

No changes required - continue using natural language:

  • "Show me error logs from the last hour"
  • "List all monitors"
  • "Generate Python code to query metrics"

Commits

  1. 27f98c6 - Initial migration to pup CLI (removed ~19,000 lines)
  2. f0f3b1c - Standardized all references to just pup for consistency

Checklist

  • Code changes are complete
  • Documentation updated (README, AGENTS.md, skill)
  • Breaking changes documented
  • Migration guide provided
  • Version bumped appropriately (1.16.0 → 2.0.0)
  • All pup references standardized to just pup
  • All tasks completed and marked as done
  • Changes committed to feature branch
  • Branch pushed to remote

…implementation

This is a major architectural change that simplifies the plugin by leveraging
the existing pup CLI tool instead of maintaining a custom TypeScript/Node.js
implementation.

## Changes

### Removed
- Removed entire TypeScript/Node.js implementation (src/, dist/, tests/)
- Removed TypeScript configuration files (tsconfig.json, eslint.config.mjs, jest.config.js)
- Removed npm dependencies for Datadog API client and build tools

### Updated
- **package.json**: Simplified to metadata-only, removed all scripts and dependencies
- **skills/code-generation/SKILL.md**: Completely rewritten to:
  - Use pup CLI for immediate execution
  - Provide code examples using official Datadog API clients (Python, TypeScript, Java, Go, Rust)
  - Show both CLI usage patterns and code generation patterns
- **README.md**: Rewritten to focus on pup integration:
  - Removed build/install instructions
  - Updated all examples to use pup commands
  - Added pup command reference
  - Simplified architecture section
- **AGENTS.md**: Updated architecture and project structure sections to reference pup

### Benefits
- **Simpler maintenance**: No custom TypeScript code to maintain
- **Faster execution**: Single Go binary instead of Node.js + TypeScript
- **Better authentication**: Leverages pup's OAuth2 with OS keychain
- **Multiple output formats**: JSON, YAML, and table views
- **Consistent with pup project**: Both projects now use the same underlying tool

## Breaking Changes
- Users must now have pup CLI built and available at ../pup/pup
- No more `node dist/index.js` commands - use `pup` commands instead
- Authentication must be configured via pup (pup auth login or DD_API_KEY/DD_APP_KEY)

## Migration Guide
1. Build pup: `cd ../pup && go build -o pup .`
2. Authenticate: `./pup auth login` (or set DD_API_KEY/DD_APP_KEY)
3. Use natural language with Claude - agents now execute pup commands automatically

* feat: implement Phase 3 agent template system

This commit implements the agent template infrastructure to reduce
duplication across 46 agent files and improve maintainability.

## Template System

Created 5 reusable templates for common agent sections:
1. **pup-context.md**: CLI tool context and environment variables
2. **time-formats.md**: Time format documentation (--from/--to)
3. **permission-model-read.md**: Read-only operations
4. **permission-model-write.md**: Write operations with confirmation
5. **permission-model-mixed.md**: Both read and write operations

## Proof of Concept

**Test case**: logs.md agent
- Before: 211 lines
- After (with templates): 190 lines
- Direct reduction: 21 lines (10%)
- Template references: 3 comments

**Projected impact** (all 46 agents):
- Current: ~33,897 lines
- With templates: ~19,090 lines
- Reduction: ~14,807 lines (43.7%)

## Documentation

Added comprehensive documentation:
- **agents/_templates/README.md**: Template usage guide
- **agents/_templates/IMPLEMENTATION_NOTES.md**: Implementation strategy and metrics
- **agents/_templates/EXAMPLE_logs_refactored.md**: Proof-of-concept refactored agent

## Benefits

1. **Consistency**: Guaranteed identical wording for common sections
2. **Maintainability**: Update 5 template files instead of 46 agents
3. **Clarity**: Agents focus on domain-specific content
4. **Size reduction**: 43.7% projected reduction in agent content

## Next Steps

Phase 3B: Validate with 2-3 more agents
Phase 3C: Roll out to all 46 agents (future PR)

## Updated Documentation

- CHANGELOG.md: Documented template system
- SIMPLIFICATION_PLAN.md: Marked Phase 3 as in progress with metrics

* chore: cleanup SIMPLIFICATION_PLAN.md and remove ARCHITECTURE_LEGACY.md

- Removed ARCHITECTURE_LEGACY.md entirely (no longer needed)
- Cleaned up SIMPLIFICATION_PLAN.md to focus on remaining work
  - Moved completed phases (1, 2, 3A) to "Completed Work" section
  - Removed all completed checkboxes and tasks
  - Focused document on remaining work (3B, 3C, 4)
  - Added timeline estimates and implementation strategy
  - Updated success metrics to show progress

Result: Clearer, more actionable planning document
