+# Load Project Memory
+
+Read ALL `.md` files in `.specify/memory/` and output their contents. This gives you project governance context (constitution, glossary, conventions, resource standards) for the command that follows.
+
+## Steps
+
+1. **Gather**: Read every `.md` file from `.specify/memory/`.
+   - If the directory does not exist, skip it silently.
+   - If a file cannot be read, skip it and continue.
+
+2. **Output**: For each file, print a headed section:
+
+   ```
+   ## Memory: {filename}
+   
+   {file contents}
+   ```
+
+3. **Summarize**: After all files, output:
+
+   ```
+   Context loaded: {memory_count} memory files
+   ```
+
+## Usage Notes
+
+- Designed as a mandatory `before_*` hook that fires before spec-kit lifecycle commands.
+- Loads governance context only. Feature-specific reference docs are loaded by the `spec-reference-loader` extension.
+- This is a read-only operation — do NOT modify any files.
