testland/pwa-install-flow-reference

Pure reference for the PWA install flow as a test surface - the installability gate (manifest required fields per [install-criteria], registered service worker, HTTPS, ~30s user engagement), the `beforeinstallprompt` handshake (preventDefault → stash → prompt() on gesture → userChoice → appinstalled), and the `display-mode` post-install signal, with a how-to-use walkthrough and a worked Chromium install-flow assertion; per-platform paths (Android WebAPK, iOS Share menu, Firefox no-op) live in references/. Use when authoring or triaging install-flow assertions and you need the gate fields, the event contract, and the per-platform expectations in one place instead of re-reading three vendor docs.

Quality

Content

85%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

An actionable, well-structured reference with executable code, a sequenced walkthrough, and a properly offloaded one-level-deep reference file. The main weakness is conciseness: several sections restate content already covered elsewhere in the body.

Suggestions

Collapse the 'full event timeline' into a cross-reference to the stages (or trim it to only the step→stage mapping) since it re-states Stage 1/2/4 content verbatim.

Trim the References section to just citations + the per-platform link; it currently re-summarizes what each stage already said.

Drop the 'When to use' section or merge it into the Overview — its bullets duplicate the description's Use-when clause.

DimensionReasoningScore

Conciseness

Assumes Claude's PWA competence (no basic-concept padding) and is mostly efficient, but the ~250-line body has real redundancy: the 'full event timeline' re-states the stages, the References section re-summarizes what each stage already covered, and 'When to use' overlaps the description.

2 / 3

Actionability

Provides a fully executable Playwright worked example, concrete contract tables (gate cells, handshake calls) with verbatim spec quotes, and copy-paste-ready assertions — not vague direction.

3 / 3

Workflow Clarity

The 5-step 'How to use this reference' is clearly sequenced with explicit checkpoints ('A single failing cell means beforeinstallprompt never fires, so localize the failure here before touching anything downstream'), and the anti-patterns table gives error-recovery guidance.

3 / 3

Progressive Disclosure

The body is an overview that offloads per-platform depth to references/per-platform-install-paths.md, a real one-level-deep file (verified) that is clearly signaled in Stage 3, the timeline, Limitations, and References rather than nested further.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, specific description with an explicit Use-when trigger and distinct niche; it names concrete contract stages rather than gesturing vaguely. No verbosity or first/second-person voice issues.

DimensionReasoningScore

Specificity

Lists multiple concrete actions: the installability gate (manifest fields, service worker, HTTPS, ~30s engagement), the beforeinstallprompt handshake (preventDefault → stash → prompt() on gesture → userChoice → appinstalled), and the display-mode post-install signal, plus a worked Chromium assertion.

3 / 3

Completeness

Answers both 'what' (pure reference for the PWA install flow as a test surface) and 'when' via the explicit 'Use when authoring or triaging install-flow assertions and you need the gate fields, the event contract, and the per-platform expectations in one place' clause.

3 / 3

Trigger Term Quality

Covers natural terms a user triaging PWA installs would say — 'PWA install flow', 'beforeinstallprompt', 'install-flow assertions', 'manifest', 'service worker', 'display-mode' — across both gate and event-contract vocabulary.

3 / 3

Distinctiveness Conflict Risk

Carves a clear niche — the install flow as a *test surface* reference — and the body explicitly differentiates it from the sibling pwa-install-flow-tests authoring skill, making mis-triggering unlikely.
