A roadmap and task system that connects initiatives with AI-agent work, commits, and pull requests.

Use it to plan initiatives, send tasks to agents, and connect roadmap items with code changes and pull requests.

It keeps day-to-day implementation linked to larger plans, making it easier to track what was assigned and what was delivered.

one-horizon — Plugin for Claude Code by onehorizonai/skills

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/onehorizonai/skills

Made for: Claude Code.

When invoked not measured The manifest loads nothing itself; its 21 skills, 1 hook, 1 MCP server cost 1,338 tokens a session between them.

Security

Grade A, and why

one-horizon scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Contents

What it installs

The manifest is a name and a version. 21 skills, 1 hook, 1 MCP server travel with it, and installing the plugin installs all of them — 1,338 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Files

What ships with it

1 file beside marketplace.json#one-horizon in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
