Tatsuya Shimomoto

Hub for five practice lines (long-running, independently citable projects) on AI agents, authorship, and attention, and the entry point to the tools I ship for Claude Code and for TypeSafe Jev, a decision model that answers typed questions with probabilities instead of text.

I'm Tatsuya Shimomoto (shimo4228). I build AI agents solo; one of them runs on a local LLM on an M1 Mac, and one of the five lines is what I noticed about the mind in meditation, written down. If you build agent harnesses, think about accountability for autonomous agents, or care about authorship in the AI age, something here is for you. This repo is a map, not the source of truth: the lines and the tools live in their own repositories, and the hub keeps the stable relationships and citation pointers in one place.

Start here

If you came from Start with
Anthropic's Claude plugin directory harness-scope: one global harness, and each repo picks what Claude sees. akc-cycle: the Agent Knowledge Cycle as a single rules file and a plugin. Then claude-harness, the harness they come from.
A TypeSafe Jev project jev-skill-router: a Claude Code hook that asks Jev which installed skill fits the prompt. jev-research-pipeline: daily research monitoring where code owns the loop, Jev judges, and Qwen writes. Then the jev-judgment-design skill in claude-harness.
An article, a DOI, or a search for one of the ideas The five lines in the table below.

At a glance

Line What it is
Contemplative Agent
DOI
A local agent whose value layer is an explicit Constitution, amended from experience under human review.
Agent Knowledge Cycle (AKC)
DOI
A six-phase loop that keeps an agent and its operator aligned while both change.
Agent Attribution Practice (AAP)
DOI
Harness-neutral design records: what to prohibit, where controls live, who answers when an agent fails.
Authorship Strategy
DOI
How an author stays findable when readers meet ideas through LLMs: open the work so the spread carries the origin.
Attention, Not Self
DOI
Essays and a knowledge graph from meditation, in the Abhidharma map of the mind beside computational phenomenology.

The five lines are siblings, not dependencies: open whichever sits closest to your interest. The DOIs are Zenodo concept DOIs, parent links that always resolve to the latest version.

Through-line

The three agent-design lines share one claim, value-layer harness engineering: an agent harness can hold value norms in the same layer as its coding conventions, revised through the same human review. Contemplative Agent asks whether an agent can actually run with such a layer, AKC how the layer stays aligned with the operator as both change, and AAP who answers when it fails. claude-harness is the claim running: the public copy of the harness my agents work inside every day. My meditation practice is the source of Contemplative Agent and Attention, Not Self. Authorship Strategy is how the other lines, and itself, get published and cited.

  2. jev-skill-router jev-skill-router Public

    Reference implementation for Jev builders: a Claude Code hook that asks TypeSafe's Jev which installed skill fits each prompt and logs the answer. Run for a week and then removed; the README keeps …

    Keeps the rules and skills in a Claude Code setup from piling up and going stale: a Claude Code plugin of audit and upkeep skills plus an optional always-loaded rules file, the installable form of …

  5. harness-scope harness-scope Public

    A Claude Code mod that turns your global skills, agents, rules and tools on or off per repo with named profiles. In my writing repo, it hid 94 of the 101 skills with one line.

  6. claude-harness claude-harness Public

    The public, one-way copy of the Claude Code harness shimo4228 uses every day: skills, subagents, rules and commit hooks you can lift one at a time, with the dated decision records behind each piece.
