Tophat Build Install

Tophat Build Install

Use this skill to turn a user request into a concrete GitHub Actions artifact install through Tophat.

This skill is GitHub Actions only. Require:

• gh
• Tophat at /Applications/Tophat.app/Contents/MacOS/tophatctl with the gha provider installed
• a repository that already publishes GitHub Actions artifacts

Do not switch to another artifact provider from this skill.

Inputs

Collect only the missing inputs.

• Platform: ios or android.
• Repository: derive it from the current checkout first. Ask only if there is no usable GitHub remote.
• Source selector: branch, PR number, workflow run ID, or explicit artifact ID.
• Workflow: only when a new build must be triggered.
• Destination: simulator or device when it matters.
• Launch arguments: only if the app needs them.

If the user says "latest build", prefer the latest successful existing run for the requested branch instead of forcing a rebuild. If the user says "build", "rebuild", or "trigger", dispatch a new workflow run first.

Default Flow

Use this order:

1. Infer the current repository.
2. Resolve the target from the user request.
3. If the user gave an explicit artifact ID, install it directly.
4. Otherwise, look for an existing artifact first.
5. Trigger a workflow only when no suitable artifact exists or the user explicitly asked for a rebuild.

Build Resolution

Resolve the user's target into a concrete artifact. Use gh when you need to inspect PRs, workflows, runs, or artifacts. Use scripts/gha.py list-artifacts when you want the local helper to list non-expired artifacts for the current repo or a chosen selector.

The helper prefers the repository-wide artifacts endpoint, but if GitHub returns 404 there it should fall back to recent workflow runs instead of stopping immediately.

Prefer this order:

1. If the user gave an explicit artifact ID, install it directly.
2. If the user gave a workflow run ID, list artifacts and match artifact.workflow_run.id.
3. If the user gave a PR number, resolve the PR head branch and head SHA, then list artifacts for that head.
4. If the user gave a branch or commit SHA, list artifacts and match branch and-or SHA.
5. Trigger a workflow only when no matching non-expired artifact exists or the user explicitly asked for a rebuild.

scripts/gha.py list-artifacts supports these selectors:

• --ref <branch>
• --sha <commit-or-prefix>
• --pr <number>
• --run-id <database-id>

If multiple artifacts exist, ask the user which artifact to install. Do not filter artifact selection by platform because GitHub Actions artifact names may not include platform text. Use platform only as a Tophat recipe hint during install.

Install

Prefer scripts/install_artifact.py for the normal install flow. It creates a temporary recipe, calls Tophat, prints a short status line, and removes the recipe unless --keep-recipe is set.

Use /Applications/Tophat.app/Contents/MacOS/tophatctl as the Tophat CLI path. Keep that path explicit when reporting missing local tooling so agents do not guess.

Use scripts/make_recipe.py directly only when you need the raw recipe JSON.

For gha, the recipe must include:

• owner
• repo
• artifact_id

If owner and repo are omitted, infer them from Git.

Treat the known tophatctl timeout as "install may still be in progress in Tophat", not as a hard failure.

For destination=device, use only workflows that already produce signed device builds. If that path does not exist, stop and explain it.

Reference Notes

Read references/public-contract.md when you need the public Tophat schema, the GitHub Actions provider details, or command examples.
