 ## Required First Step
 
 On a new machine or teammate session, run the installer first:
 
 ```powershell

-Use `-CheckProvider` to also ping the MiniMax Anthropic-compatible endpoint. Use `-RepairSkillLinks` when the shared skill should be installed or repaired for Codex and Claude. If the `.agents` copy is missing, the installer seeds it from the repo's bundled `skill\` directory first. Use `-InstallMissing` on teammate machines when missing CLI tools should be installed automatically where supported. Never ask the installer to write API keys; it only checks whether user-scoped env vars exist.

 ```
 
-The installer also installs the repo-owned Sentrux shim into `CODE_INTEL_BIN` or `%LOCALAPPDATA%\code-intel\bin`, prepends that directory to the user PATH, and verifies `sentrux pro status`. The shim auto-activates local open-source Pro features, forwards all non-`pro` commands to the real `sentrux.exe` when present, and falls back to `sentrux-lite-core.ps1` for portable `scan`, `health`, `check`, `gate`, and `plugin list/validate`.

-The installer applies the repo-owned Sentrux V overlay by default because the upstream Windows `vlang` standard plugin package is incomplete in Sentrux 0.5.7. The overlay lives under `overlays\sentrux\vlang`, installs with `Install-SentruxVlangOverlay.ps1`, and should make `sentrux plugin list` show `vlang v0.2.0 [v]`. Use `Test-SentruxVlangOverlay.ps1` to prove the plugin builds a real V graph with 2 files, 1 import, and 1 call. Use `-SkipSentruxVlangOverlay` only when explicitly testing upstream plugin behavior.

 It exposes exactly these tools: `scan`, `health`, `session_start`, `session_end`, `rescan`, `check_rules`, `evolution`, `dsm`, `test_gaps`, and `what_if`. Root paths are valid inputs: the wrapper automatically excludes dependency, build-output, cache, and bundled static-asset code from governed source metrics, and reports the filtered material under `scope.excluded_by_reason`. Use narrower scopes only when the team intentionally wants a separate baseline for a subsystem.

Subject: [PATCH 5/6] Fix cross-platform-smoke CI failures on rebased PR2
 branch

- test-skill-development-benchmark.ps1: match SKILL.md's forward-slash doc links
- run-code-intel.ps1: derive file byte count from already-read content instead of a second Get-Item filesystem call, avoiding a TOCTOU failure on macOS/Ubuntu
- skill/SKILL.md: replace hardcoded D:\\ absolute repo paths with portable \ references; fix stray backslash doc links
- tools/check-hardcoded-paths.ps1: stop flagging legitimate \C:\Users\Administrator\AppData\Local/USERPROFILE/APPDATA references and doc example paths; add a precise self-referential absolute-path detector for the real bug class
