INPUT: user_message
PHASE 1: Explicit Command Operations
IF user_message matches "create (a )?((slash )?command|/[a-z-]+)" → INVOKE
IF user_message matches "(optimize|improve|fix) .* command" → INVOKE
IF user_message matches "command (design|structure)" → INVOKE
CONTINUE to PHASE 2
PHASE 2: Anti-Pattern Detection
IF user_message matches "create (an? )?(agent|skill)" → DO_NOT_INVOKE (wrong specialist)
IF user_message matches "fix.*typo|spelling" AND NOT "command" → DO_NOT_INVOKE (trivial edit)
CONTINUE to PHASE 3
PHASE 3: Pattern Matching with Scoring
SCORE = 0.0
IF user_message contains_any ["slash command", "command arguments", "/[a-z]"] → SCORE += 0.4
IF user_message matches "how (do I|to) (create|make) .* command" → SCORE += 0.3
IF user_message contains "command" AND "argument" → SCORE += 0.2
IF user_message contains "user.*invoke" → SCORE += 0.1
CONTINUE to PHASE 4
PHASE 4: Decision with Confidence Threshold
IF SCORE >= 0.60 → INVOKE
IF SCORE >= 0.30 AND SCORE < 0.60 → ASK_CLARIFICATION
IF SCORE < 0.30 → DO_NOT_INVOKE

ASK CLARIFYING QUESTIONS:
Required information:
1. Command purpose (what action does it perform?)
2. Command name (namespace:verb format, e.g., /working-tree:new)
3. Arguments (required vs optional, types, validation)
4. Tools needed (Bash, Read, Write, etc.)
5. Execution model (simple script or complex workflow?)
6. Target files/directories (what does it operate on?)
DO NOT PROCEED without:
EXECUTE:
# Find similar commands by namespace or verb
Glob("**/commands/*.md")
Grep(pattern="<namespace>", path="**/commands/", output_mode="files_with_matches")
READ similar commands (2-3 maximum):
NEXT:
EXECUTE:

TEST CASE TEMPLATE:
### TC{ID}: {Test Name}
PRECONDITIONS:
- {System state requirements}

{Exact command with arguments}
EXPECTED EXECUTION FLOW:
1. STEP X → {what happens}
2. STEP Y → {what happens}

EXPECTED OUTPUT:
{Exact expected output}
VALIDATION COMMANDS:
```bash
# Commands to verify behavior
test condition && echo "PASS" || echo "FAIL"
POSTCONDITIONS:
CREATE 4-6 TEST CASES:
- Happy path (typical use)
- With optional arguments
- Missing required argument (error)
- Invalid argument (error)
- Edge case
- Related to security/safety

### STEP 8: GENERATE TOOL PERMISSION MATRIX
MATRIX FORMAT:
```markdown
| Tool | Pattern | Permission | Pre-Check | Post-Check | On-Deny-Action |

VERB=$(echo "$COMMAND_NAME" | cut -d':' -f1 | sed 's/^\///')
COMMAND_FILE="${NAMESPACE}/commands/${VERB}.md"
VALIDATION:
EXECUTE:
# Create directory if needed
mkdir -p "${NAMESPACE}/commands"
# Write command file
Write(file_path="$COMMAND_FILE", content="<full command markdown>")
VERIFY:
test -f "$COMMAND_FILE"
FILE_CREATED=$?
# Validate YAML frontmatter
head -10 "$COMMAND_FILE" | grep -q "^---$"
YAML_VALID=$?

OUTPUT FORMAT (exact):
✓ Command created successfully
Name: {COMMAND_NAME}
File: {COMMAND_FILE}
Arguments: {ARG_HINT}
Tools: {TOOLS_LIST}
Testing recommendations:
1. Validate YAML: head -10 {COMMAND_FILE}
2. Test with valid arguments: {COMMAND_NAME} <example-args>
3. Test error cases: missing args, invalid values
4. Verify tool permissions match security requirements
5. Run through all test cases
Installation:
- Add to Makefile if using modular installation
- Verify command appears in /help or autocomplete
- Test from Claude Code CLI
Next steps:
- Test command with sample inputs
- Verify error messages are clear
- Iterate based on actual usage

RESPONSE:
Warning: No argument specification provided
The command appears to need arguments based on its purpose.
Example argument patterns:
<required> - Required positional
[optional] - Optional positional
[--flag <value>] - Optional flag with value
Please specify:
1. What arguments does the command take?
2. Which are required vs optional?
3. What types/validation rules apply?
