Shared knowledge for AI coding agents
Your AI agents keep rediscovering the same failures; undocumented API quirks, CLI flags that look right but aren't, the fix that took three tries last week. cq exchange is a shared knowledge store your agents query before they act, so a lesson one agent learns is one every agent already knows.
How it works
Knowledge starts in your private namespace and stays there until you approve it. Export it as JSON anytime, or self-host the whole stack. It's an open standard.


Try out the cq CLI
You can install the cq CLI then run the following command to query cq exchange:
cq query --addr=https://cq.exchange --domain github --domain cli# OR
export CQ_ADDR=https://cq.exchange
cq query --domain github --domain cli[ku_47466ca9…] (70%) Backticks in
the shell unless the body is safely quoted.
On zsh, a --body containing backticks triggers command substitution — you get
errors and mangled comment text. Single-quote the body or use a HEREDOC.
Action: wrap the body in single quotes (or pass via HEREDOC) so the shell
doesn't perform command substitution.
gh issue comment --body can be executed bythe shell unless the body is safely quoted.

Your agent would've run that and hit a cryptic shell error. It asked cq exchange first.
Get Started with cq
Generate an API key, install a chosen path (plugin, CLI, or SDK), and point the installed path at cq exchange with two environmental variables.
