Use this skill to generate and apply a clear title and structured description for a GitHub Pull Request by deep-investigating all changed files. Use it when the user opens a new PR, when a PR's title or description is missing or stale, or when the user says "update this PR", "describe this PR", or "write a summary for this PR." Applies the result directly via gh pr edit.
Use when rebasing current branch onto a target branch, especially when the working tree has uncommitted changes, the local target ref may be behind its remote, or the rebase risks conflicts that need user review.
Expand a goal-create file into a detailed, implementation-ready task breakdown. Use when a user has a goal under Docs/Goals and wants it expanded into per-Task blocks (files, interfaces, code snippets, bash commands, acceptance criteria) ready to hand to goal-execute. Triggers: "detail this goal", "expand the goal", "break the goal into tasks", "create task breakdown", "plan the goal", "write implementation steps for this goal", "make an epic-style plan from this goal". Do not use for executing the goal, writing test cases, or verifying completed work.
Generate tree-format data structure documentation for Unity JSON schemas (db_*.json tables like db_TTE, db_DBSE). Use when the user pastes/shares a table of fields with short keys (a0, b1, c2...), wants a hierarchical tree diagram of a JSON data structure, asks to "create tree format", "data structure doc", "document db_XXX.json", or "generate data struct markdown". Output is a markdown file with a tree showing parent-child nesting (Object arrays → child objects) plus per-level field reference tables.
Use for Unity engineering standards: C# code, asset managers, Addressables, analytics, LiveOps, config, server API, IAP, prefab, Canvas UI, material, shader, draw calls, batching, debugging, optimization, reviews, project investigation, tests, plans, todos, acceptance criteria, and technical docs.
Diagnose Unity bugs from compile errors to stack traces, runtime failures, and tricky logic issues; gather reproduction details, trace the code path, prove the root cause with evidence, and report options without changing code unless asked.
Use when the user provides a Unity requirement, goal, feature idea, or bug objective — with or without a proposed solution or technical approach. Detects whether the user supplied a solution or only a goal, then either designs a Unity solution (tech approach, risks, concerns, options) or evaluates the supplied solution against Unity standards and project context. Triggers: "design a solution", "evaluate this approach", "review my solution", "find a technical approach", "is this solution good", "solution for", "tech approach for", "how should we build/fix this".
Use this skill to process GitHub Pull Request review comments one at a time: read each comment, investigate whether it is valid, fix valid findings, commit each fix separately, reply with the resolution reason, and resolve the review thread. Use it when the user says to resolve PR review comments, fix reviewer feedback, address review comments, or investigate comments on a PR.
