What is buildable-reviewer?

A review checklist for Buildable prototypes, which are generated app prototypes. It checks build correctness, interface completeness, states, accessibility, responsiveness, and whether the app stays local-first.

Use it to review a prototype against its specification and rubric, inspect reported files, and optionally run its build or type checks.

It provides a static quality check that can catch structural and usability problems before manual browser or device testing.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add jj-jamen/buildable-plugin-skills --skill reviewer

Clone the repo

git clone --depth 1 https://github.com/jj-jamen/buildable-plugin-skills

Made for: Claude Code, Codex.

Or install buildable, the plugin that ships this one along with the rest of its 3 skills, 6 commands, 1 MCP server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00031	$0.00461
Opus 5	$0.00015	$0.00230
Sonnet 5	$0.00006	$0.00092
Haiku 4.5	$0.00003	$0.00046

Security

Grade A, and why

buildable-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Buildable Reviewer Skill

Use this skill to review generated prototypes against the app spec and quality rubric.

Resolve all referenced paths from the Buildable plugin or repository root.

buildable review is a static/local quality gate. Treat it as a strong first pass for structure, local-first guardrails, source coverage, responsive-layout risk, accessibility signals, and optional build checks; it does not replace manual QA, real device/simulator checks for mobile, or browser/screenshot review when visuals matter.

Activation

Use only when reviewing an app/prototype against Buildable specs or rubrics. Do not activate globally for ordinary code review.

Reference Loading Contract

Mandatory order:

Run buildable review from the selected app workspace when available. Pass a path only when reviewing a different folder.
Load the app spec and selected rubric.
Load only files related to reported issues.
Do not load all templates.
Do not load unrelated archetypes or starter source.

Workflow

Run buildable review when the CLI is available. Add --build only when the user wants typecheck/build scripts run and dependencies are installed.
Read the app spec and selected quality rubric.
Run available build, typecheck, lint, or test commands (or rely on review --build).
Inspect the generated UI when possible — start the app and run buildable preview --url <url> from the app workspace to render it, screenshot it, and catch runtime/visual errors that build checks miss.
Check required interactions, state coverage, responsive behavior, and accessibility.
Produce a focused fix list.
Apply fixes when operating as the active coding agent.

Review Priorities

build correctness
primary workflow
missing interactions
empty/loading/error states
mobile and desktop layout
accessible form controls
unnecessary backend or hosted features

Output Format

Lead with blocking issues, then polish issues, then checks run. If no issues remain, say so and note residual risks.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
