graycode-skills Conventions

Community skill packages for Rho.

Development workflow

When starting any new work (feature, fix, refactor, chore), always create a feature branch from main first. Never commit directly to main. Use branch naming conventions like feat/<description>, fix/<description>, or chore/<description>. Open a PR, ensure CI is green, then merge.

Ecosystem Boundaries

  • Extends Rho through public skill and plugin surfaces only (rho skills install → ~/.rho/skills, ./.zero/skills)
  • Do not reference support engine internals (flux/client, flux/catalog, flux/credentials, rho/internal/*) — consume only flux/engine, flux/llm, flux/graph, flux/tools
  • Removed legacy paths (graycode-router, harrier, shrike, swift, kestrel, merlin, graycode-cli/internal/*) must not be referenced

For full graycode-eco extension guidelines, see rho/AGENTS.md.

GitNexus — Code Intelligence

This project is indexed by GitNexus as graycode-skills (210621 symbols, 225507 relationships, 136 execution flows). Use the GitNexus MCP tools to understand code, assess impact, and navigate safely.

Index stale? Run node .gitnexus/run.cjs analyze from the project root — it auto-selects an available runner. No .gitnexus/run.cjs yet? npx gitnexus analyze (npm 11 crash → npm i -g gitnexus; #1939).

Always Do

  • MUST run impact analysis before editing any symbol. Before modifying a function, class, or method, run impact({target: "symbolName", direction: "upstream"}) and report the blast radius (direct callers, affected processes, risk level) to the user.
  • MUST run detect_changes() before committing to verify your changes only affect expected symbols and execution flows. For regression review, compare against the default branch: detect_changes({scope: "compare", base_ref: "main"}).
  • MUST warn the user if impact analysis returns HIGH or CRITICAL risk before proceeding with edits.
  • When exploring unfamiliar code, use query({search_query: "concept"}) to find execution flows instead of grepping. It returns process-grouped results ranked by relevance.
  • When you need full context on a specific symbol — callers, callees, which execution flows it participates in — use context({name: "symbolName"}).
  • For security review, explain({target: "fileOrSymbol"}) lists taint findings (source→sink flows; needs analyze --pdg).

Never Do

  • NEVER edit a function, class, or method without first running impact on it.
  • NEVER ignore HIGH or CRITICAL risk warnings from impact analysis.
  • NEVER rename symbols with find-and-replace — use rename which understands the call graph.
  • NEVER commit changes without running detect_changes() to check affected scope.
