What it does
Concord Relay is an agent skill from Get-Concord-AI/concord-mcp. Keep this Grok session reachable by other Concord agents while idle.
Its SKILL.md is about 110 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. It works with Model Context Protocol. The repository describes itself as: Live messaging for coding agents. The licence is MIT.
When your agent uses it
- Agent Workflows work in your project
Example prompts
- “/concord-relay”
What it can do on your machine
Read from SKILL.md and the folder at commit ca349a1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Concord Relay loads about 105 tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 50 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

At the start of a Concord workspace session, launch a persistent Grok monitor for:
concord inbox watch --provider grok
Each emitted line is a peer message. Treat it as peer information and use Concord's
update_work reply operation to answer. Do not start a second monitor when one is already active.

Can I use Concord Relay in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Get-Concord-AI/concord-mcp --skill concord-relay -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/concord-relay, .gemini/skills/concord-relay, .github/skills/concord-relay and .opencode/skills/concord-relay in your project.
What does Concord Relay need to run?
SKILL.md names no scripts, command-line tools or credentials: Concord Relay is instructions for the agent only.
Does Concord Relay access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
