The habits that work for a small task don't disappear at scale — they need a real structure layered on top. Here's how context management and subagents actually fit into a bigger project.
Letting context grow unchecked across many unrelated tasks in one long session degrades quality well before you'd hit any hard technical limit. Starting a fresh session for each distinct piece of work — the same habit that works for small tasks — matters even more on a bigger project, where there's more surface area for context to get muddled.
A subagent gets its own clean context window for a specific piece of work — genuinely useful when a project has independent pieces that don't need to share context with each other. It adds real overhead, though, so it's a tool for genuine complexity, not a default for every task.
See Claude Code Subagents for the full breakdown of when a separate context window actually pays off.
Small, scoped, reviewable pieces are still the core unit of work on a big project — what changes is needing a real plan for how those pieces relate to each other, which a small project doesn't need to think about at all.
Treating the whole project as one continuous session instead of a deliberate sequence of scoped pieces — the same failure mode as an oversized single task, just larger and harder to notice until it's already caused real rework.

When a project has genuinely independent pieces that don't need to share context — a subagent gets its own clean context window for its piece, which helps on large, multi-part work but adds real overhead on anything smaller.
No — the core discipline (small, scoped, reviewable pieces) still applies, but bigger projects need a real structure for how those pieces relate, which small projects don't need to think about.
Treating the whole project as one continuous session instead of a sequence of scoped pieces — that's what causes context bloat and unfocused results, the same failure mode as an oversized single task, just at a larger scale.
