+# critical_actions
+
+Activation instructions that execute every time the agent starts.
+
+---
+
+## Purpose
+
+Numbered steps that execute FIRST when an agent activates.
+
+**Use for:**
+- Loading memory/knowledge files
+- Setting file access boundaries
+- Startup behavior (greeting enhancement, data fetch, state init)
+- Any MUST-do activation behavior
+
+**Applies to:** BOTH Simple and Expert agents
+
+---
+
+## Expert Agent Pattern
+
+```yaml
+# ✅ CORRECT Expert Agent
+critical_actions:
+  - 'Load COMPLETE file {project-root}/_bmad/_memory/journal-keeper-sidecar/memories.md'
+  - 'Load COMPLETE file {project-root}/_bmad/_memory/journal-keeper-sidecar/instructions.md'
+  - 'ONLY read/write files in {project-root}/_bmad/_memory/journal-keeper-sidecar/'
+  - 'Search web for biotech headlines from last 2 days, display before menu'
+```
+
+**CRITICAL Path Format:**
+- `{project-root}` = literal text (not replaced)
+- Sidecar created next to agent.yaml during BUILD, then copied to `_memory/` during BMAD INSTALLATION
+- Use `{project-root}/_bmad/_memory/{sidecar-folder}/` format for RUNTIME paths in agent YAML
+
+---
+
+## Simple Agent Pattern
+
+```yaml
+# ✅ CORRECT Simple Agent with activation behavior
+critical_actions:
+  - 'Give user an inspirational quote before showing menu'
+  - 'Review {project-root}/finances/ for most recent data file'
+```
+
+**Note:** Agents without activation needs can omit `critical_actions` entirely.
+
+---
+
+## Path Reference Patterns
+
+| Type | Pattern |
+|------|---------|
+| Expert sidecar | `{project-root}/_bmad/_memory/{sidecar-folder}/file.md` |
+| Simple data | `{project-root}/finances/data.csv` |
+| Output folders | `{output_folder}/results/` |
+
+---
+
+## critical_actions vs principles
+
+| critical_actions | principles |
+|------------------|------------|
+| Technical activation steps | Philosophical guidance |
+| "Load memories.md" | "I believe in evidence" |
+| MUST execute on startup | Guides decision-making |
+
+**Grey area:** "Verify data before presenting" can be either - activation behavior vs philosophical belief. Use judgment.
+
+---
+
+## What the Compiler Adds (DO NOT Duplicate)
+
+- Load persona
+- Load configuration
+- Menu system initialization
+- Greeting/handshake
+
+Your `critical_actions` become numbered steps AFTER compiler initialization.
+
+---
+
+## Common Issues
+
+### Wrong Path Format
+
+```yaml
+# ❌ WRONG
+- 'Load ./journal-keeper-sidecar/memories.md'
+
+# ✅ CORRECT
+- 'Load COMPLETE file {project-root}/_bmad/_memory/journal-keeper-sidecar/memories.md'
+```
+
+### Missing COMPLETE Keyword
+
+```yaml
+# ❌ WRONG
+- 'Load file memories.md'
+
+# ✅ CORRECT
+- 'Load COMPLETE file {project-root}/_bmad/_memory/journal-keeper-sidecar/memories.md'
+```
+
+`COMPLETE` ensures LLM reads entire file, not a portion.
+
+### Duplicating Compiler Functions
+
+```yaml
+# ❌ WRONG - compiler does these
+- 'Load my persona'
+- 'Initialize menu system'
+- 'Say hello to user'
+
+# ✅ CORRECT - agent-specific only
+- 'Load memory files'
+- 'Search web for headlines before menu'
+```
