HarnessTap CloudOpen catalog · free on day one

Personas for your coding agent.

Compose what runs, swap how it runs, and install the same deck on Claude, Codex, and Cursor from one git repo.

Context · environment · layer · deckDeck model
Deck
Your personal ordered collection of layers—cherry-pick from org catalogs and local layers, then apply to projects with `deck apply`.
Layer
A reusable, versioned recipe you combine and apply at project or machine level—publish to a catalog or share through an export.
Profile
A layer tagged `profile`—a switchable global preset you activate with `profile use` to update machine-wide harness files.
Resource
The smallest piece of agent configuration you can mix and match—either context-side (what the agent knows) or environment-side (how it runs).
Environment
Named runtime settings you switch in one command—move between dev, staging, and production, or between customers and teams, without rebuilding your setup.

One catalog for your org. Native on every harness.

HarnessTap Cloud stores your organization's catalogs of layers, resources, and decks. The CLI pulls approved releases, publishes updates, and syncs the same setup to Claude, Cursor, and Codex on each developer's machine.

The open catalog ships free on day one — browse layers, review version history, and pull any release after review.

How HarnessTap works

Separate what you run from how you run it, then sync the result to every harness.

What vs how

What

Context-side resources

skills, rules, MCP servers, hooks, agents, commands

How

Environment-side values

env vars, model config, permissions

Composition

plugin refs, layer refs

MCP server definitions describe what to connect to; tokens and URLs are supplied as environment values.

Three payoffs

  • Switchable configuration

    Same layer, new environment in one command

    Declare what each capability needs once. Swap prod, staging, or personal values without copying the whole setup.

  • Context curation

    Turn skills and MCP servers off when you are done

    Stack only what a task needs. Remove the loadout cleanly instead of letting context accrete.

  • Cross-harness reach

    One repo, native on Claude, Cursor, and Codex

    Claude installs from the repo. Cursor and Codex read the generated native files from the same deck.

Configure once. Switch anywhere.

Every harness ships its own plugin format. Config values freeze in settings. Context stacks up because it is easier to add than remove. HarnessTap separates what you run (context-side resources: skills, MCP, rules) from how you run it (environment-side values: secrets, models, permissions), composed into layers and cascaded into every harness.

HarnessTap CLI

hd deck use staging

Same plugins, new environment. Re-bind tokens, models, and permissions in one local command. The web app publishes decks; environment swap runs in the CLI.

A plugin anyone can install. A deck only you can reconfigure.

HarnessTap adds optional governance without blocking plain OSS installs

Without HarnessTap

  • claude plugin install works on the repo as-is
  • Other harnesses read AGENTS.md, .cursor/rules/, and similar generated files

With HarnessTap

  • CLI: swap prod and staging in one command
  • Curate context, detect drift, sync every harness from .harnesstap/deck.json

HarnessTap is pure upside. Never required to use what you publish.

Team governance

Ship layers and decks from the CLI, review releases in Cloud, and pull approved setups into every project.
