📚 Description

The plugin hooks are bash and need jq. A Windows host without bash ran none of them, so the worktree, PR skill, email, and GitHub routing rules did not apply there.

Each of the 10 registered hooks now has a PowerShell 7 twin with the same name and the same stdin and stdout contract. Two helpers, check-config.ps1 and command-text.ps1, mirror the sourced bash helpers, including the heredoc and quote scanner.

  • plugin.windows.json registers the twins as pwsh -File "${CLAUDE_PLUGIN_ROOT}/hooks/<name>.ps1", in the order and with the timeouts of plugin.json.
  • pnpm sync:context on Windows copies the hooks, that manifest as plugin.json, and the opencode plugin to the same ~/.local/share/wolfstar-agent-kit layout Linux uses. Claude Code on Windows installs that directory as the wolfstar-agent-kit-hooks plugin.
  • The opencode plugin reads a pwsh -File "<script>" command and runs a .ps1 hook in pwsh.
  • release.ts bumps the version in plugin.windows.json too.
  • A hook change is now two edits, the .sh and the .ps1. powershell-hooks.test.ts runs both over one command list and fails when the answers differ. It also fails when the two manifests drift.
  • Codex has no Windows hooks yet. codex.json is unchanged.

A Windows host without bash could run none of the plugin hooks. Each
registered hook now has a .ps1 twin, registered by plugin.windows.json,
installed by the Windows sync, and run by the opencode plugin through pwsh.
A parity test feeds both twins one command list.

Tip

Set github.draw: on-demand in .github/pr-lens.yml and PR Lens stops drawing pull requests on its own. Comment @pr-lens draw on a pull request when you want that one drawn

🪧 More tips
  • Run npx skills add coldteadotai/pr-lens, then tell your coding agent: "Diagram the change you just made with PR Lens and attach it to the pull request."
  • Run npx @coldtea/pr-lens-cli analyze --base origin/main on a branch, then npx @coldtea/pr-lens-cli render .pr-lens/graph.json. Same lenses, your own model key, before the pull request exists
  • Click the link under each diagram to open it on a canvas you can zoom, pan and step through
  • The diagrams are links. Click one to open it on the canvas, then press W or click play to walk through the change
  • Open a diagram on the canvas, then press W or click play to walk through the change one step at a time
  • The CLI's render reads .github/pr-lens.yml and applies your renames, exclusions and lane pins at draw time
  • Set github.comment.collapsed: true in .github/pr-lens.yml to fold the comment behind one View architecture… row. Drawing still runs as before
  • Add .github/workflows/pr-lens.yml with coldteadotai/pr-lens/packages/action@v0 and your model provider's key as its api-key to run PR Lens from your own CI. Any /chat/completions endpoint works
  • After a push, tick Redraw to draw the latest commit
  • Switch GitHub to dark mode and the diagrams follow. The moving dots are this pull request's data in motion
  • Set github.description: false in .github/pr-lens.yml to stop PR Lens adding buttons to your PR descriptions

session-start.ps1 prints unnamed where its bash twin prints nothing

For a package.json that fails to parse, session-start.ps1 keeps $name = 'unnamed' and prints Node Project: unnamed, while session-start.sh lets jq fail to an empty name and prints Node Project:. The twins disagree and the parity test never feeds a broken package.json.

Fix: Start $name empty and assign it only after ConvertFrom-Json succeeds, matching jq -r '.name // "unnamed"'; or add a broken-package.json case to powershell-hooks.test.ts.

   Problem: `session-start.ps1` prints `unnamed` where its bash twin prints nothing. For a `package.json` that fails to parse, `session-start.ps1` keeps `$name = 'unnamed'` and prints `Node Project: unnamed`, while `session-start.sh` lets `jq` fail to an empty name and prints `Node Project: `. The twins disagree and the parity test never feeds a broken `package.json`.
   Fix: Start `$name` empty and assign it only after `ConvertFrom-Json` succeeds, matching `jq -r '.name // "unnamed"'`; or add a broken-`package.json` case to `powershell-hooks.test.ts`.

merged-branch-guard test runs on main so it cannot fail

The test named ’allows every command off a feature branch’ initialises git init -b main, so both hooks exit at the main guard before any GitHub lookup. It never exercises a feature branch and passes even if the merged-PR path is wrong.

Fix: Initialise the test repository on a feature branch (git init -q -b feature/x) so both hooks run past the main check that the test name describes.

-and $package.name drops an empty or zero package name

When package.json has "name":"" or "name":0, $package.name is falsy so the hook keeps unnamed, while the bash twin jq -r '.name // "unnamed"' prints the empty value; the session-start project line then differs between the two hooks.

Fix: Match jq’s //: keep unnamed only when $package.PSObject.Properties['name'] is missing or $package.name is $null or $false, not when it is empty or zero.

Starting pwsh costs more than starting bash, so a loaded host timed out
a hook that the manifest gave no timeout.
