Loopengine
evanyan22 · Agent
LoopEngine is a TypeScript runtime for building AI agents, each defined by a system prompt, a set of tools, permission rules and a model, and run through a ReAct loop written as a single function. A create command scaffolds a standalone project with a starter agent and command line and HTTP adapters. A browser admin page shows and edits each agent's skills, tools, rules and secrets, and an ability installs a tool, its skill and its rules in one step.
Written by ooruby from the README of loopengine 0.1.62.

Why it's useful
You can follow every step an agent takes and change the rules that gate its tools, without a chain language or hidden control flow.
What you could do with it
- Scaffold a project with its starter agent and run it as an HTTP server on your machine.
- Send a risky tool call to Slack with approve and deny buttons and resume the run when someone answers.
- Install an ability that adds a tool, its skill file and its permission rules to one of your agents.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.
In its maker's words
Runtime for tool-using AI agents with a transparent ReAct loop.

- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.1.62, the file with digest sha512-tvwb0RIsDNi5MOb7Gx2bFVOuQ+8c0sd1J7XwS9RnL3J11Hi1OLOSc93RMHcntwGiR3SGxdOW4FHWJRBU3k5atw==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
Run it with:
npx -y loopengine@0.1.62Pinned to 0.1.62, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.

It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
