What is opt-editor-install?

A skill for installing, setting up, upgrading, or migrating the @reopt-ai/opt-editor package in another project. It chooses the appropriate setup path based on whether the package is already installed.

Use it for opt-editor installation, updates, version-specific upgrades, AI streaming setup, checks, or dry runs.

It avoids treating a new installation like an upgrade and helps keep the project’s agent instructions and package configuration consistent.

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.

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	$0.00092	$0.01310
Opus 5	$0.00046	$0.00655
Sonnet 5	$0.00018	$0.00262
Haiku 4.5	$0.00009	$0.00131

Security

Grade A, and why

opt-editor-install 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.

How it starts

The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.

opt-editor Install

This is NOT the opt-editor you know. Read node_modules/@reopt-ai/opt-editor/dist/docs/ before writing code.

When to apply

Consumer project depends on @reopt-ai/opt-editor. Triggers: "install", "init", "setup", "upgrade", "update" — with or without an opt- / editor prefix.

Invocation

/opt-editor-install              # Auto-branch (missing → init, installed → upgrade)
/opt-editor-install --with-ai    # Init + AI streaming integration
/opt-editor-install 2.0.0        # Upgrade to a specific version
/opt-editor-install --dry-run    # Analyze only

Step 1 — Pin agent rules into AGENTS.md / CLAUDE.md

Source: the module's own agent-rules file once it ships one (@reopt-ai/opt-editor does not, as of 2.0.0). Fallback: agent-rules.md bundled with this skill. Wrap content between:

<!-- BEGIN:reopt/opt-editor-agent-rules -->
…content from source…
<!-- END:reopt/opt-editor-agent-rules -->

Idempotent: replace only between markers.

Step 2 — Consumer-side setup (this skill owns; docs cannot)

Public npm registry — no token or scoped .npmrc entry is required. Inspect the project .npmrc and npm config get @reopt-ai:registry; if the scope still resolves to GitHub Packages, remove only the legacy project entry @reopt-ai:registry=https://npm.pkg.github.com. Preserve unrelated registry/auth settings, and ask before changing user/global npm config.
Prereqs — Node 20+, React 19+, bun or npm. AI integration uses optional peers ai >= 7 and zod >= 3; do not install them for a non-AI editor.
App wiring — properties of the consumer app:
- import "@reopt-ai/opt-editor/styles.css" at the app root.
- Catalog file (catalog.ts or similar) — block-definition registry.
- AI endpoint (when --with-ai): a Vercel AI SDK–compatible route.
2.0 upgrade gate — move runtime Zod schema values (patchOpSchema, patchOpsArraySchema, createEditorOperationSchema, catalog schema builders) from @reopt-ai/opt-editor/server to /schemas; type-only imports may stay on /server, and /ai-sdk imports are unchanged. Before loading persisted V1 JSON, migrate props → attrs and rich-text attrs.text → canonical content, with a backup and a data-level dry run. The README's bun run migrate:v1-to-v2 is a source-repo script and is not shipped in the npm tarball; do not invoke it as a consumer command.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
