# Trellis Instructions

These instructions are for AI assistants working in this project.

Use the `/trellis:start` command when starting a new session to:
- Initialize your developer identity
- Understand current project context
- Read relevant guidelines

Use `@/.trellis/` to learn:
- Development workflow (`workflow.md`)
- Project structure guidelines (`spec/`)
- Developer workspace (`workspace/`)

If you're using Codex, project-scoped helpers may also live in:
- `.agents/skills/` for reusable Trellis skills
- `.codex/agents/` for optional custom subagents

Keep this managed block so 'trellis update' can refresh the instructions.

# GitNexus — Code Intelligence

This project is indexed by GitNexus as **or_llm_agent** (2746 symbols, 4646 relationships, 160 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.
