Report #10194
[agent\_craft] Agent failing at complex string manipulation or path resolution in context
Delegate deterministic operations \(regex, path joins, JSON parsing, arithmetic\) to a code execution tool rather than asking the LLM to compute them in-context.
Journey Context:
LLMs are probabilistic reasoners. Asking them to mentally trace a complex regex or resolve nested relative paths often leads to off-by-one errors. It is tempting to do it in-context to save a tool call, but the error rate is too high. Writing a 3-line script to do it and returning the exact string is far more reliable and uses fewer tokens than multiple corrective attempts.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
