Deliverd

Skills

Three open-source agent skills — approval, ethics and artifact — that teach an agent when to ask a person and how, and the Claude Code plugin that bundles them.

A skill is a set of instructions an agent reads before it acts. Deliverd's three are open source under the MIT licence, in deliverd-dev/deliverd-skills on GitHub. They teach judgement — when to ask, how to write a request, what to do with the answer — and use the MCP server, the SDKs or the CLI when one is set up. Each also works in plain conversation when none is.

The skills

Approval
When to stop and ask a person before a consequential action — anything irreversible, anything that spends money or reaches people outside the conversation — how to write a request someone can decide from a phone, how to wait, and how to act on the answer, including an approver's corrections.
Ethics
Noticing when work could harm or wrong a person, and putting that concern in front of whoever decides rather than around them. It also covers behaving well when an organisation's ethics rules flag or refuse a request, and helping an administrator write those rules.
Artifact
Building a well-made, self-contained HTML page — a report, a dashboard, a plan, a prototype — and then offering to publish it. The craft half works with no account at all.

Install one

Claude Code, Codex and Cursor read skills from the same place, so one install covers all three. Install the ones you want:

Approval

npx skills add deliverd-dev/deliverd-skills --skill approval

Ethics

npx skills add deliverd-dev/deliverd-skills --skill ethics

Artifact

npx skills add deliverd-dev/deliverd-skills --skill artifact

Approval and ethics are written to work together: the ethics skill decides that a person should weigh something, and the approval skill is how the agent asks.

The Claude Code plugin

In Claude Code, the plugin installs the Deliverd MCP server and all three skills at once. Add the marketplace, then install the deliverd plugin it lists from /plugin:

claude plugin marketplace add deliverd-dev/deliverd-skills

The first time a tool runs, Claude Code opens a browser for you to approve the connection. See Authentication.

What they hold to

  • Everything the approval skill names — MCP tools, request and response fields, CLI flags, SDK environment variables — is tested against the code before each release, so it teaches what the product does.
  • The ethics skill's principles, effects and refusal codes are tested the same way against the ethics module. See Ethics concerns.
  • The artifact skill's examples are run through the same scanners a publish runs, so it does not teach a page the platform would refuse.

The skills are MIT licensed: read them, fork them, or lift the parts you want. The service they optionally publish to is not open source.
