What is the 'T+6 Months' philosophy in Claude Code?

It is the principle of designing for the model capabilities expected in six months, treating current workarounds as temporary scaffolding that should be deleted as models naturally improve.

What is the benefit of using multiple sub-agents?

Sub-agents provide independent context windows, allowing for parallel exploration of different hypotheses without the 'anchoring bias' that can occur in a single long-running conversation.

When should I use Plan Mode versus immediate coding?

Plan Mode is recommended for roughly 80% of sessions, especially for tasks involving multiple components, architectural decisions, or unfamiliar codebases where the root cause is unclear.

How do I know when my CLAUDE.md file needs a reset?

You should delete and restart your CLAUDE.md if it exceeds 500 lines, contains contradictory instructions, addresses obsolete model limitations, or if Claude begins ignoring parts of the file.
