# HarnessLink

> HarnessLink is the controller for AI coding agents such as Claude Code, Codex, omp and pi: one gateway for every model call, shared memory they all search, and sync and restore of your setup across machines.

HarnessLink is the controller for your coding agents - it routes their model calls, gives them shared memory, banks what they do, and syncs and restores your setup. You code in omp, Claude Code, Codex, pi, and others. Also written Harness Link; the command is `hnl`. Install on macOS or Linux with `curl -fsSL https://harnesslink.sh/install.sh | bash`, on Windows with `irm https://harnesslink.sh/install.ps1 | iex`. Plans, in GBP: Free (£0), Pro (£10 a month), Team (£22 per user a month), Enterprise (contact us). Every link below is the page as Markdown.

## Docs

- [Installing HarnessLink](https://harnesslink.sh/docs.md): Install HarnessLink on macOS, Linux or Windows with one command, connect Claude Code, Codex, omp and pi, and sign in to sync memory across machines.
- [Shared memory for Claude Code, Codex and more](https://harnesslink.sh/harnesses.md): Share memory between Claude Code, Codex, omp, pi, Antigravity and Cursor: what HarnessLink captures from each harness, how to set it up, and its limits.
- [Using HarnessLink (guide)](https://harnesslink.sh/docs/usage.md): Using HarnessLink day to day: Ask, history, policies, shared memory, resuming sessions across harnesses, profile sync, templates, delegation, runs and cost.
- [Installing HarnessLink (guide)](https://harnesslink.sh/docs/install.md): The full HarnessLink install guide: requirements, Windows, install options, verifying, the first-run onboarding, updating, troubleshooting and uninstalling.
- [Memory Banking (guide)](https://harnesslink.sh/docs/memory-banking.md): How HarnessLink turns each finished turn in omp, Claude Code, Codex, pi and Antigravity into a Markdown memory entry, when banking runs, and what reads it.
- [What HarnessLink captures from each harness](https://harnesslink.sh/docs/multi-harness.md): What HarnessLink captures from omp, Claude Code, Codex, pi, Antigravity and Cursor after setup, and how it stays a controller rather than a harness.
- [Claude Code memory and MCP tools](https://harnesslink.sh/harnesses/claude-code.md): Give Claude Code memory that Codex, omp and pi share: HarnessLink adds context hooks and MCP memory tools, banks every turn and routes calls through a gateway.
- [Codex memory, MCP tools and context hooks](https://harnesslink.sh/harnesses/codex.md): Share memory between Codex and Claude Code: HarnessLink adds Codex context hooks and MCP memory tools, banks every turn and routes model calls via a gateway.
- [omp (oh-my-pi) memory and MCP tools](https://harnesslink.sh/harnesses/omp.md): HarnessLink for omp (oh-my-pi): a managed context extension, MCP memory tools, gateway routing for the Anthropic and Codex providers, and every turn banked.
- [pi coding agent memory and gateway](https://harnesslink.sh/harnesses/pi.md): HarnessLink for the pi coding agent: transcripts and prompts captured, every turn banked into shared memory, and model calls routed through the local gateway.
- [Antigravity CLI transcripts and memory](https://harnesslink.sh/harnesses/antigravity.md): HarnessLink for the Antigravity CLI: prompts and conversations synced as they change and one memory entry banked per conversation. No gateway, hooks or MCP.
- [Cursor MCP memory tools and session files](https://harnesslink.sh/harnesses/cursor.md): Use HarnessLink's MCP memory tools in Cursor to search what Claude Code and Codex banked. Cursor chats are not captured: its editor database is not read.
