List all sub-issues (children) of a parent GitHub issue, with completion summary. Use depth parameter (1-3) to fetch nested sub-issue trees in a single call. Default depth=1 returns direct children only.
AI agents call ralph_hero__list_sub_issues to retrieve information from Ralph Hero without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves hierarchical issue data from GitHub Projects V2 without modifying state. It is a pure read operation analogous to querying or listing. The depth parameter is a filtering/traversal mechanism, not a destructive or executable action. Misuse would at worst over-fetch data, posing negligible risk.
From the tool's definition Tool name contains 'list' and description states 'List all sub-issues (children)' with 'fetch' capability. No mention of creation, modification, deletion, code execution, or financial operations. The depth parameter controls query recursion, not side effects.

List all sub-issues (children) of a parent GitHub issue, with completion summary. Use depth parameter (1-3) to fetch nested sub-issue trees in a single call. Default depth=1 returns direct children only. It is categorised as a Read tool in the Ralph Hero MCP Server, which means it retrieves data without modifying state.
Register the Ralph Hero MCP server in PolicyLayer and add a rule for ralph_hero__list_sub_issues: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Ralph Hero. Nothing to install.
ralph_hero__list_sub_issues is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the ralph_hero__list_sub_issues rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for ralph_hero__list_sub_issues. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
ralph_hero__list_sub_issues is provided by the Ralph Hero MCP server (ralph-hero-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
