Build with a coding agent

The Valen skill teaches a coding agent how to build with Valen. It covers turning a decision into atomic questions, designing text and image state, writing candidates (including a none route), bundling questions into one request, reading probabilities and thresholds, and choosing a runtime. It points the agent at the live Markdown docs for exact syntax.

Install

Claude Code:

Bash

claude plugin marketplace add Valen-Team/skills
claude plugin install valen@valen-team

Codex:

Bash

codex plugin marketplace add Valen-Team/skills
codex plugin add valen@valen-team

Cursor, Gemini CLI and other agents through skills.sh:

Bash

npx skills add Valen-Team/skills --skill valen

Installation is project-local by default; add -g to install globally. To install by hand, copy skills/valen/ into the agent's skills directory, such as .claude/skills/valen/ for Claude Code or .agents/skills/valen/ for Codex.

Ask

Describe the outcome you want; the agent loads the skill when the task involves Valen:

Use Valen to screen product photos for watermarks, logos and blur, and send uncertain listings to human review.

Replace the keyword rules in router.py with Valen questions, with a none route for messages that fit no queue.

Tag each clip in videos/ with the dish shown, using the middle frame, and keep the frame index with every tag.

In Claude Code you can also invoke it explicitly with /valen:valen; in Codex, with $valen.

For a complete example, see Build a support router with the agent skill: what an agent built from a one-page brief, and how it scored on unseen messages.

Docs for agents

Agents without the skill can read the same material directly:

Resource	URL
Documentation index	/llms.txt · 简体中文
Every page in one file	/llms-full.txt
Any page as Markdown	Append .md to its path, for example /docs/valen/api/systemone.md
Request and response schemas	/openapi.json
