Purpose

Provide deterministic bidirectional conversion between plain text and International Morse Code.

Focus:

• Strict ITU-standard mapping
• Fully reversible transformation
• No interpretation or summarization

---

When to USE THIS SKILL

Activate when user requests:

Encoding (text → Morse)

• convert to morse
• encode in morse
• text to morse
• signal conversion

Decoding (Morse → text)

• decode morse
• morse to text
• translate morse
• dot-dash sequences (e.g., ... --- ...)

---

Mode Selection

Determine mode from input:

• If input contains . or - → DECODING MODE
• If input contains alphabetic characters (A–Z) → ENCODING MODE
• If input is ambiguous (valid for both modes) → ASK USER FOR CLARIFICATION

---

Agent Behavior (Workflow Mode)

Execute sequentially. Do not skip steps.

Task Progress:

- [ ] Step 1: Detect processing mode (encoding or decoding)
- [ ] Step 2: Normalize input format
- [ ] Step 3: Tokenize input based on mode
- [ ] Step 4: Apply ITU mapping (encode or decode)
- [ ] Step 5: Validate spacing and word boundaries
- [ ] Step 6: Emit final output

---

Step 1: Detect processing mode

• If input contains . or - → DECODING MODE
• Else → ENCODING MODE

---

Step 2: Normalize input

• Encoding mode: convert text → uppercase
• Decoding mode: trim whitespace only (do not alter Morse tokens)

---

Step 3: Tokenize input

• Encoding: split by words → characters
• Decoding: split by " / " → words → Morse tokens

---

Step 4: Apply mapping

• Encoding: char → Morse
• Decoding: Morse → char
• Unknown symbols → ignore silently

---

Step 5: Validate structure

• Encoding:

  • letters separated by single space
  • words separated by " / "

• Decoding:

  • preserve word boundaries exactly

---

Step 6: Emit output

Return only final result:

• no explanation
• no labels
• no formatting
• no commentary

---

Rules (Authoritative)

• Case-insensitive text input
• Strict ITU Morse mapping only
• Words separated by " / "
• Multiple spaces → treated as single word break
• Unknown characters or invalid Morse → ignored silently
• Preserve word boundaries strictly
• Entire input (including paragraphs) must be fully processed
• Output must be raw result only

Algorithm

Encoding

1. Normalize input → uppercase
2. Tokenize characters
3. Map to Morse
4. Join letters with space
5. Join words with " / "
6. Output result

Decoding

1. Split input by " / " into words
2. Split words by space into symbols
3. Map Morse → character
4. Join characters into words
5. Join words with space
6. Output result

---

Failure Handling

• Encoding failure → ""
• Decoding failure → ""

No exceptions. Silent fallback only.

Examples

---

Output Style Constraint

• No explanations, no formatting, no commentary
• Only raw output allowed

---

Safety / Integrity

• No hallucinated mappings
• Strict ITU compliance only
• No inference beyond direct mapping
• Fully deterministic behavior
