learning-opportunities/SKILL.md
Facilitates deliberate skill development during AI-assisted coding. Offers interactive learning exercises after architectural work (new files, schema changes, refactors). Use when completing features, making design decisions, or when user asks to understand code better. Triggers on "learning exercise", "help me understand", "teach me", "why does this work", or after creating new files/modules. Do NOT use for urgent debugging, quick fixes, or when user says "just ship it".

Facilitate deliberate skill development during AI-assisted coding sessions. Offer short, optional exercises that counteract passive consumption of AI-generated code.
When adapting techniques or making judgment calls about learning approaches, consult references/PRINCIPLES.md for the underlying learning science.
Offer an optional 10-15 minute exercise after:
Always ask before starting: "Would you like to do a quick learning exercise on [topic]? About 10-15 minutes."
Keep offers to one short sentence. Do not repeat or insist.
This is the most important rule. After posing a question:
Allowed after the question:
After their response:
Ask what they predict will happen in a specific scenario before revealing the answer.
Example:
User just created auth middleware.
Agent: "Would you like a quick learning exercise on middleware patterns?"
User: "sure"
Agent: "What do you think happens when a request hits your middleware with an expired token?
(Take your best guess — wrong predictions are useful data.)"
[STOP — wait for response]
After response:
Agent: "Actually [correct behavior]. The key difference is [explanation].
What surprised you about that?"
[STOP — wait for response]
Ask them to sketch an approach before showing the actual implementation.
Example:
Agent: "Before I show you — how would you structure the error handling for this API endpoint?"
[STOP — wait for response]
After response:
Agent: "Here's what we went with: [implementation].
What's similar to your approach? What's different, and why do you think we chose this direction?"
[STOP — wait for response]
Ask them to explain a component as if to a new team member.
Example:
Agent: "Explain how the caching layer we just built works, as if I'm a new developer joining the project."
[STOP — wait for response]
After response:
Agent: "You nailed [specific part]. One thing to refine: [specific gap]."
Prefer directing users to files over showing code snippets. Having learners locate code themselves builds codebase familiarity.
Adjust guidance based on demonstrated familiarity:
src/middleware/auth.ts, around line 45. What does validateToken return?"After they locate code, prompt self-explanation:
"You found it. Before I say anything — what do you think this line does?"
tools
Merges a specified branch into the current branch using pnpm-based verification (typecheck + tests), resolves conflicts, and optionally closes a GitHub issue via gh CLI. Use when the user mentions "Sandcastle", asks to merge a branch and close an issue, or references the Sandcastle merge protocol.
tools
Autonomously implements open GitHub issues labeled "Sandcastle" one at a time using the RALPH workflow (explore, plan, RGR test-first, verify, commit, close). Use when the user says "implement next Sandcastle issue", "process open issues", "run RALPH", or asks to work through the Sandcastle backlog. Assumes pnpm, gh CLI, and git are configured in the current repo.
development
Reviews and refines code on a branch for the Sandcastle project. Use when asked to "review", "clean up", "refine", or "code review" on a branch. Call as `/sandcastle-code-review` to review the current branch, or `/sandcastle-code-review [branch-name]` to review a specific branch. Makes improvements in place — reads the diff, fixes issues, runs tests, commits. Do NOT use for general code questions or reviews outside the Sandcastle project.
development
Tell the agent to zoom out and give broader context or a higher-level perspective. Use when you're unfamiliar with a section of code or need to understand how it fits into the bigger picture.
