Based on SOC occupation classification
Create or update GitHub Pull Requests with the gh CLI, including deciding whether to create a new PR or only push based on existing PR merge status. Use when the user asks to open/create/edit a PR, generate a PR body/template, or says 'PRを出して/PR作成/gh pr'. Defaults: base=develop, head=current branch (same-branch only; never create/switch branches).
Bootstrap the unity-cli toolchain for Unity Editor automation. Use when verifying the unity-cli binary, discovering available tools, invoking a tool by name, switching active Unity instances, or troubleshooting host/port and install-mode issues. Do not use once a more specific Unity workflow skill applies; defer to `unity-scene-create`, `unity-csharp-edit`, `unity-editor-tools`, or another domain skill instead.
Manage Unity assets and import metadata with unity-cli. Use when the user asks to refresh the asset database, inspect asset info, create or modify a material, create an animation clip or sprite atlas, update import settings, or analyze asset dependencies before moving or deleting files. Do not use for Addressables groups or content builds; use `unity-addressables`. Do not use for scene object edits; use `unity-gameobject-edit`.
Browse Unity Technologies' official UnityCsReference C# source as a read-only local cache. Use when the user asks about the exact signature, behavior, or internal implementation of a Unity API, when comparing API differences between Unity versions, or when validating LLM-suggested Unity code against the canonical source. Do not use for editing project code (use `unity-csharp-edit`). Do not use for project-local script reading (use `unity-csharp-navigate`).
Implement, fix, and refactor Unity C# code with unity-cli write tools. Use when the user wants to change behavior in .cs files, create or rewrite scripts, update multiple C# files together, rename a symbol, add or remove members, or change project or package settings as part of a code change. Do not use for read-only inspection with no planned edit; use `unity-csharp-navigate` instead.
Explore Unity C# code without modifying files. Use when the user asks to read scripts, search text, find a symbol, trace references, inspect namespaces or packages, or understand where a class, method, or field is used. Do not use for code edits, renames, or refactors; use `unity-csharp-edit`. Do not use for scene inspection; use `unity-scene-inspect`.

| description | Check GitHub PR status with the gh CLI, including unmerged PR detection and post-merge new-commit detection for the current branch. |
Check PR status for the current branch with gh and report a recommended next action.
This skill is check-only:
head branch, and base branch.
head: current branch (git rev-parse --abbrev-ref HEAD)base: default develop unless user specifiesgit status --porcelaingit fetch origingh pr list --head <head> --state all --jsonnumber,state,mergedAt,updatedAt,url,title,mergeCommit,baseRefName,headRefNameNO_PR + recommended action CREATE_PRmergedAt == null
-> UNMERGED_PR_EXISTS + recommended action PUSH_ONLYmergedAtmergeCommit.oidgit merge-base --is-ancestor <merge_commit> HEADHEAD, count commits after merge:
git rev-list --count <merge_commit>..HEADALL_MERGED_WITH_NEW_COMMITS + CREATE_PRALL_MERGED_NO_NEW_COMMITS + NO_ACTIONHEAD:

Do not return raw JSON as the default output. If JSON is explicitly requested by the user, append it after the human summary.
Recommended status values:
NO_PRUNMERGED_PR_EXISTSALL_MERGED_WITH_NEW_COMMITSALL_MERGED_NO_NEW_COMMITSCHECK_FAILEDRecommended action values:
CREATE_PRPUSH_ONLYNO_ACTIONMANUAL_CHECKOutput 1-3 lines using a signal prefix + action keyword on line 1.
| Prefix | Action | Meaning |
|---|---|---|
>> | CREATE PR | Create a new PR |
> | PUSH ONLY | Push to existing PR |
-- | NO ACTION | Nothing to do |
!! | MANUAL CHECK | Manual check required |
Per-status format:
NO_PR:
>> CREATE PR — No PR exists for <head> -> <base>.
UNMERGED_PR_EXISTS (2 lines):
> PUSH ONLY — Unmerged PR open for `<head>`.
PR: #<number> <url>
ALL_MERGED_WITH_NEW_COMMITS (2 lines):
>> CREATE PR — <N> new commit(s) after last merge (#<pr_number>).
head: <head> -> base: <base>
ALL_MERGED_NO_NEW_COMMITS:
-- NO ACTION — All PRs merged, no new commits on <head>.
CHECK_FAILED (2 lines):
!! MANUAL CHECK — Could not determine PR status.
Reason: <reason>
head: <head> -> base: <base>
Append the following line only when the worktree is dirty:
(!) Worktree has uncommitted changes.
| Status | Prefix | Action | Template |
|---|---|---|---|
NO_PR | >> | CREATE PR | No PR exists |
UNMERGED_PR_EXISTS | > | PUSH ONLY | Unmerged PR open |
ALL_MERGED_WITH_NEW_COMMITS | >> | CREATE PR | N new commit(s) |
ALL_MERGED_NO_NEW_COMMITS | -- | NO ACTION | All PRs merged |
CHECK_FAILED | !! | MANUAL CHECK | Could not determine |
NO_PR:
>> CREATE PR — No PR exists for `feature/my-branch` -> `develop`.
UNMERGED_PR_EXISTS:
> PUSH ONLY — Unmerged PR open for `feature/my-branch`.
PR: #456 https://github.com/org/repo/pull/456
ALL_MERGED_WITH_NEW_COMMITS:
>> CREATE PR — 3 new commit(s) after last merge (#123).
head: feature/my-branch -> base: develop
ALL_MERGED_NO_NEW_COMMITS:
-- NO ACTION — All PRs merged, no new commits on `feature/my-branch`.
CHECK_FAILED:
!! MANUAL CHECK — Could not determine PR status.
Reason: Could not resolve merge commit and fallback comparison failed
head: feature/my-branch -> base: develop
With dirty worktree (appended to any status):
>> CREATE PR — 3 new commit(s) after last merge (#123).
head: feature/my-branch -> base: develop
(!) Worktree has uncommitted changes.
