Follow AGENTS.md for the canonical rules; this file adds Claude Code–specific deltas. Cursor-specific notes live only in AGENTS.md.

Scope

See the Scope table in AGENTS.md for read/write/execute/off-limits boundaries. Cursor-specific workflow notes also live only in AGENTS.md.

Model Configuration

  • Primary: Pin per Claude Code / Anthropic org policy (explicit model id). Do not rely on an unversioned latest alias for governed workflows.
  • Fallback: As configured in Claude Code (organization default or user override).
  • Notes: The GitNexus CLI analyzer does not call an LLM.

Execution Sequence (complex tasks)

Same discipline as AGENTS.md: before large multi-step work, state which AGENTS.md / GUARDRAILS.md rules apply, current Scope, and planned validation commands (npm test, tsc, etc.). When pausing, summarize progress in the chat or a local scratch file (do not add HANDOFF.md to the repo), then /clear and resume with that summary.

Claude Code hooks

Prefer PreToolUse hooks for hard gates (e.g. tests before git_commit). Adapt hook commands to gitnexus/ npm scripts.

Context budget

If always-on instructions grow, load deep conventions via conditional reads (e.g. “When writing new code, read STANDARDS.md”) instead of pasting long blocks here. In Cursor, prefer .cursor/index.mdc plus optional .cursor/rules/*.mdc globs (see AGENTS.md § Context budget).

Reference Documentation

  • This repository: AGENTS.md (Cursor + monorepo notes), ARCHITECTURE.md, CONTRIBUTING.md, GUARDRAILS.md.
  • Call-resolution DAG: See ARCHITECTURE.md § Call-Resolution DAG. Shared pipeline code in gitnexus/src/core/ingestion/ must not name languages — use LanguageProvider hooks instead (see AGENTS.md).
  • GitNexus: .claude/skills/gitnexus/; MCP and indexed-repo rules live only in AGENTS.md (gitnexus:start … gitnexus:end). See GitNexus rules below.

Changelog

Date Version Change
2026-04-13 1.3.0 Updated GitNexus index stats after DAG refactor.
2026-03-24 1.2.0 Removed duplicated gitnexus:start block and scope table; replaced with pointers to AGENTS.md.
2026-03-23 1.1.0 Updated agent instructions to match AGENTS.md.
2026-03-22 1.0.0 Added structured header and changelog.

GitNexus rules

See the <!-- gitnexus:start --> … <!-- gitnexus:end --> block in AGENTS.md for the canonical MCP tools, impact analysis rules, and index instructions.

GitNexus — Code Intelligence

This project is indexed by GitNexus as GitNexus (26675 symbols, 35395 relationships, 300 execution flows). Use the GitNexus MCP tools to understand code, assess impact, and navigate safely.

If any GitNexus tool warns the index is stale, run npx gitnexus analyze in terminal first.

Always Do

  • MUST run impact analysis before editing any symbol. Before modifying a function, class, or method, run gitnexus_impact({target: "symbolName", direction: "upstream"}) and report the blast radius (direct callers, affected processes, risk level) to the user.
  • MUST run gitnexus_detect_changes() before committing to verify your changes only affect expected symbols and execution flows.
  • MUST warn the user if impact analysis returns HIGH or CRITICAL risk before proceeding with edits.
  • When exploring unfamiliar code, use gitnexus_query({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 gitnexus_context({name: "symbolName"}).

Never Do

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