[agent\_craft] Over-planning burns the context window before any code is written

Plan cheaply for bounded tasks: if a task touches fewer than five files and has a clear test, act directly. Escalate to explicit plan-and-approve only for cross-cutting changes or after a failed first attempt.

Journey Context:
Agents often emit elaborate plans for trivial edits, wasting tokens and time. Conversely, unplanned cross-file changes create rollback cascades. The heuristic is simple: small scope and clear success signal means act; large scope or ambiguous success means plan first. This mirrors how senior developers work and matches the 'act when the path is clear, plan when it is not' guidance from agent-building practitioners.
