AI agents

Your AI checks its own work. 

SIGSHIP speaks MCP, the standard way AI coding tools connect to helpers. Add it once and your agent won’t say “done” until the check says Ready.

Add to Cursor Add to VS Code

The Cursor and VS Code buttons open the editor with SIGSHIP’s MCP server ready to add. In Claude Code, paste the two commands: /plugin marketplace add sigship/sigship, then /plugin install sigship@sigship.

sigship_check
Runs all 17 checks and returns what to fix.
sigship_explain
Explains one finding in plain words with a fix.
AGENTS.md rule (added by npx sigship init)
## Definition of done

Before saying work is finished, run `npx sigship`.
If it is not GO, fix what it reports and run it again. Only say the work is done after it exits 0.
