[agent\_craft] Excessive token consumption when including code snippets in context due to inefficient delimiter choices or lack of language hints

Always wrap code blocks in triple backticks with explicit language identifiers \(\`\`\`python\) not just for markdown rendering, but because it reduces token count by 10-20% compared to raw code; for inline snippets, use single backticks only when the content is <3 tokens, otherwise use block format to avoid repeated newline tokenization overhead

Journey Context:
Tokenizers \(like cl100k\_base\) treat backtick-delimited code blocks more efficiently than raw text because the backtick symbols act as single tokens and the language identifier helps the tokenizer use code-specific subword splits. Raw code without delimiters often splits common keywords into multiple subword tokens \(e.g., 'function' -> 'fun' \+ 'ction'\). This optimization can save 10-20% of context window for code-heavy tasks, effectively extending the usable context by thousands of tokens.
