Unity Docs

Resolve the uncertainty, then stop. Reuse project/version evidence unless the target changes or sources conflict. Choose one sufficient source: metadata/source for signatures, docs for behavior. Existing compiler diagnostics and matching metadata/source outrank prose. Never compile or launch Unity just for docs.

Paths below are relative to this skill's installation. Use Python 3.10+ (python3, typically python or py -3 on Windows); quote paths for the shell. Windows/macOS/Linux detection is automatic.

• Engine: run scripts/inspect_unity_api.py QUERY directly; don't reread its code. Use a fully qualified type/member, e.g. UnityEngine.GameObject.SetActive or UnityEngine.GameObject.activeSelf; add --assembly NAME when known. Inspect overloads only as needed. Type queries don't enumerate members; no --members exists. See --help for options. Project/editor detection is automatic; outside projects add --project-root PATH. If discovery fails, set UNITY_EDITOR_PATH to the local editor executable or installation directory, or UNITY_EDITOR_ROOT to its versioned installations' parent. revisionVerified: false forbids claiming an exact revision match. Exit 3 means unresolved, not absent: check spelling, declaring type and assembly, then relevant package source/versioned docs. Report remaining uncertainty.
• Packages: scripts/doc_cache.py package NAME --project-root PATH resolves local sources against the lockfile; search with available tools (rg if installed). Missing/ambiguous sources aren't verified. Use vendor sources for vendor APIs.
• Explanation: scripts/doc_cache.py web URL --find TERM; omit --find for full text. Use explicitly versioned docs.unity3d.com URLs derived from the project or resolved package; confirm the page version. Pages retain URL/fetch date and are reused until --refresh. Browse current release notes/Issue Tracker live.

Persistent XML/metadata cache: .cache/unity-docs under the user's home directory; override with UNITY_DOCS_CACHE. Changed sources invalidate evidence; --refresh rebuilds it. Refresh web pages only when freshness matters.

Broaden only for an unresolved gap; don't repeat equivalent searches. Answer with result and relevant signature/source; version details only when material. Omit the lookup diary.
