Tyler Longwell 4b69401517 feat: Add summon extension replacing subagent tool and skills extension
Implements unified 'summon' platform extension with two intuitive tools:
- load: Inject knowledge into current context ("teach me this")
- delegate: Run tasks in isolated subagents ("do this for me")

Key features:
- Source discovery from recipes, skills, agents with priority ordering
- Skill/agent frontmatter parsing with Claude model shorthand translation
- Sync and async delegation with background task tracking
- MOIM status reporting for background tasks with rounded durations
- Nested delegation prevention (subagents cannot spawn subagents)
- 60s TTL caching for source discovery

Removes:
- subagent_tool.rs (523 LOC)
- skills_extension.rs (865 LOC)
- builtin_skills/ directory

Adds:
- summon_extension.rs (1834 LOC) - consolidated implementation

The summon extension provides a cleaner mental model while maintaining
all existing functionality. Builtin skills are now inlined in the
extension.

goose

a local, extensible, open source AI agent that automates engineering tasks

Discord CI

goose is your on-machine AI agent, capable of automating complex development tasks from start to finish. More than just code suggestions, goose can build entire projects from scratch, write and execute code, debug failures, orchestrate workflows, and interact with external APIs - autonomously.

Whether you're prototyping an idea, refining existing code, or managing intricate engineering pipelines, goose adapts to your workflow and executes tasks with precision.

Designed for maximum flexibility, goose works with any LLM and supports multi-model configuration to optimize performance and cost, seamlessly integrates with MCP servers, and is available as both a desktop app as well as CLI - making it the ultimate AI assistant for developers who want to move faster and focus on innovation.

Why did the developer choose goose as their AI agent?

Because it always helps them "migrate" their code to production! 🚀
