Agentic Harness Core
jitsusama · Agent
Agentic harness core holds the business logic under an agent harness: state machines, guardian decisions and a quest and test-driven development model. Each domain is a TypeScript module with no host dependency, plus a command line that reads and writes its own state file on every call. Adapters for hosts such as Pi and Claude Code handle storage, presentation and confirmation. It suits people building a harness, or writing skills and hooks that call it from Bash.
Written by ooruby from the README of @jitsusama/agentic-harness.core 0.6.18.
Not claimed by its maker.
Why it's useful
The logic is separate from any one host, so the same loop and decisions can be reused by different agent hosts through their adapters.
What you could do with it
- Record the planning step of a red-green-refactor loop by piping a JSON action into the tdd command.
- Check where a test-driven loop stands by asking the command line for its status from a saved state file.
- Call the state machines from a Bash-invoked skill or a hook dispatcher without keeping a background process running.
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
- Licence and provenance
- finding
- no LICENCE file at the root (.)
- Data handling disclosed
- finding
- no statement of what it reads, writes or sends (README.md)
Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.
What this does not cover
- Everything. Treat it as you would software from anywhere else.

In its maker's words
Pi-agnostic business logic for agentic-harness: state machines, guardian decisions, quest/TDD domain model.

Static scanned
- 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 0.6.18, the file with digest sha512-fdX4ASR/KV12NX1T87Pb+Jr0FhEWjqDapVhLPLbXplBPepu8rq5OPWe9bR3kIoUm1VACglhrm/UjaV4/JmbP4A==, 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 @jitsusama/agentic-harness.core@0.6.18Pinned to 0.6.18, 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.
