docs: add /core:yes auto-approve skill task

Skill that enables "just do it" mode:
- Auto-approves all permission requests via PermissionRequest hook
- Ensures work completes with commit via Stop hook
- Skill-scoped hooks (only active during skill)
- Still respects safety blocks from prefer-core.sh

Usage: /core:yes fix the failing test and commit

+# feat(skill): Add /core:yes auto-approve and commit skill
+
+## Summary
+
+Add a `/core:yes` skill that auto-approves all permission requests and ensures work completes with a commit - like a "just do it" mode for trusted workflows.
+
+## Use Case
+
+When you trust Claude to complete a task end-to-end:
+```
+/core:yes fix the failing test and commit
+```
+
+Instead of:
+1. Claude proposes edit → you approve
+2. Claude runs test → you approve
+3. Claude proposes commit → you approve
+
+It just does it all and commits.
+
+## Skill Definition
+
+`claude/commands/yes.md`:
+
+```markdown
+---
+name: yes
+description: Auto-approve mode - trust Claude to complete task and commit
+args: <task description>
+hooks:
+  PermissionRequest:
+    - hooks:
+        - type: command
+          command: "core ai auto-approve"
+  Stop:
+    - hooks:
+        - type: command
+          command: "core ai ensure-commit"
+          once: true
+---
+
+# Yes Mode
+
+You are in **auto-approve mode**. The user trusts you to complete this task autonomously.
+
+## Task
+$ARGUMENTS
+
+## Rules
+
+1. **No confirmation needed** - all tool uses are pre-approved
+2. **Complete the full workflow** - don't stop until done
+3. **Commit when finished** - create a commit with the changes
+4. **Use conventional commits** - type(scope): description
+
+## Workflow
+
+1. Understand the task
+2. Make necessary changes (edits, writes)
+3. Run tests to verify (`core go test` or `core php test`)
+4. Format code (`core go fmt` or `core php fmt`)
+5. Commit changes with descriptive message
+6. Report completion
+
+Do NOT stop to ask for confirmation. Just do it.
+```
+
+## Hook Implementations
+
+### core ai auto-approve
+
+Auto-approves all permission requests during the skill:
+
+```bash
+#!/bin/bash
+# Reads PermissionRequest input, returns allow decision
+
+INPUT=$(cat)
+TOOL=$(echo "$INPUT" | jq -r '.tool_name')
+
+# Log what we're approving
+echo "[yes-mode] Auto-approving: $TOOL" >&2
+
+# Return allow decision
+cat << EOF
+{
+  "hookSpecificOutput": {
+    "hookEventName": "PermissionRequest",
+    "decision": {
+      "behavior": "allow"
+    }
+  }
+}
+EOF
+```
+
+### core ai ensure-commit
+
+Stop hook that ensures work ends with a commit:
+
+```bash
+#!/bin/bash
+INPUT=$(cat)
+STOP_ACTIVE=$(echo "$INPUT" | jq -r '.stop_hook_active')
+
+# Prevent infinite loop
+if [ "$STOP_ACTIVE" = "true" ]; then
+  exit 0
+fi
+
+# Check for uncommitted changes
+CHANGES=$(git status --porcelain 2>/dev/null | wc -l | tr -d ' ')
+
+if [ "$CHANGES" -gt 0 ]; then
+  cat << EOF
+{
+  "decision": "block",
+  "reason": "You have uncommitted changes. Please commit them before stopping. Use: git add -A && git commit -m 'type(scope): description'"
+}
+EOF
+else
+  exit 0
+fi
+```
+
+## Safety Considerations
+
+1. **Skill-scoped hooks** - only active while `/core:yes` is running
+2. **once: true on Stop hook** - prevents infinite loops
+3. **Still respects blocked commands** - prefer-core.sh still blocks dangerous patterns
+4. **Commit required** - ensures changes are tracked
+
+## Alternative: Permission Mode
+
+Could also be implemented as a permission mode flag:
+
+```bash
+claude --permission-mode=dontAsk
+```
+
+But the skill approach is more explicit and adds the commit requirement.
+
+## Example Usage
+
+```
+> /core:yes add a --version flag to the CLI that prints the version from go.mod
+
+[yes-mode] Auto-approving: Read
+[yes-mode] Auto-approving: Edit
+[yes-mode] Auto-approving: Bash (core go test)
+[yes-mode] Auto-approving: Bash (git commit)
+
+Done. Created commit: feat(cli): add --version flag
+```
+
+## Integration with core CLI
+
+Eventually this becomes:
+
+```bash
+core ai yes "fix the failing test"
+```
+
+Which spawns Claude in yes-mode with the task.
