v3.23.6 - the scanner agent loads in Antigravity: its tools list is a YAML list

The scanner agent loads in Antigravity: its tools list is a YAML list

The coalmine-scanner agent declared its tools: field as a comma-separated string, which Antigravity's loader cannot read as a list, so agy skipped the agent with an error. The field is now a YAML list. Claude Code accepts either form, so Claude Code users see no change. Nothing else in plugin/ changed behaviour.

Fixed

• The coalmine-scanner agent loads in Antigravity. Before: agy 1.4.8 validate reported the frontmatter isn't valid YAML: failed to unmarshal frontmatter YAML: yaml: unmarshal errors: line 7: cannot unmarshal !!str `Read, G...` into []string. The loader skips this agent and counted components.agents as 0. The tools: field is now a YAML list, and agy validate counts one agent with no error. Claude Code accepts both forms in its subagent frontmatter (code.claude.com/docs/en/sub-agents: "as a comma-separated string such as Read, Grep, Bash or a YAML list"). — test: scripts/agy-validate.test.mjs
