[synthesis] Agent deletes or overwrites wrong file due to relative path confusion

Disable relative paths entirely in agent tool definitions. Force all file operations to use absolute paths, and inject the current working directory into the system prompt. Validate paths against a whitelist before execution.

Journey Context:
LLMs struggle with spatial relationships and path traversal. An agent might assume its shell is in /project/src when it is in /project, running rm -r src or writing to ./config.json in the wrong location. The failure is catastrophic and silent until later. Synthesizing OS path resolution rules with LLM spatial reasoning limits shows that relative paths are an unacceptable risk; absolute paths combined with strict validation prevent the agent from accidentally escaping its intended scope.
