+# Sync Documentation
+
+After feature work, update the affected documentation to reflect code changes.
+
+## Steps
+
+1. **Identify changed files** — Run `git diff main --name-only` to find modified Go files.
+
+2. **Map files to docs** — Use this mapping to determine which docs need updates:
+
+   | Changed path pattern | Affected docs |
+   |---------------------|---------------|
+   | `forge-core/runtime/` | `docs/runtime.md`, `docs/hooks.md` |
+   | `forge-core/security/` | `docs/security/overview.md`, `docs/security/egress.md` |
+   | `forge-core/tools/` | `docs/tools.md` |
+   | `forge-core/llm/` | `docs/runtime.md` |
+   | `forge-core/memory/` | `docs/memory.md` |
+   | `forge-core/scheduler/` | `docs/scheduling.md` |
+   | `forge-core/secrets/` | `docs/security/secrets.md` |
+   | `forge-core/skills/` | `docs/skills.md` |
+   | `forge-core/channels/` | `docs/channels.md` |
+   | `forge-cli/cmd/` | `docs/commands.md` |
+   | `forge-cli/runtime/` | `docs/runtime.md` |
+   | `forge-cli/server/` | `docs/architecture.md` |
+   | `forge-cli/channels/` | `docs/channels.md` |
+   | `forge-cli/tools/` | `docs/tools.md` |
+   | `forge-plugins/` | `docs/channels.md`, `docs/plugins.md` |
+   | `forge-ui/` | `docs/dashboard.md` |
+   | `forge-skills/` | `docs/skills.md` |
+   | `forge.yaml` / `types/` | `docs/configuration.md` |
+
+3. **Read the diff** — For each mapped doc, read the relevant `git diff main` output to understand what changed.
+
+4. **Update docs** — For each affected doc:
+   - Read the current doc file
+   - Identify sections that need updating based on the code changes
+   - Edit the doc to reflect new behavior, flags, types, or configuration
+   - Preserve the navigation footer and header
+
+5. **Check cross-references** — If you added a new feature/section, ensure:
+   - The README.md documentation table links to it (if it's a new doc)
+   - Related docs cross-link to it where appropriate
+   - Navigation order is still correct
+
+6. **Validate** — Run a quick broken-link check:
+   ```bash
+   grep -rn '\[.*\](.*\.md)' README.md docs/ | while read line; do
+     file=$(echo "$line" | grep -oP '\(.*?\.md\)' | tr -d '()')
+     dir=$(dirname "$(echo "$line" | cut -d: -f1)")
+     target="$dir/$file"
+     [ ! -f "$target" ] && echo "BROKEN: $line"
+   done
+   ```
+
+## Rules
+
+- One topic per file; split if >300 lines
+- Start each doc with a one-sentence summary
+- Use tables over bullet lists for comparisons
+- Link, don't repeat — cross-reference other docs
+- Keep ASCII diagrams (they render everywhere)
+- Code examples must be runnable
