context-economy

Protect the context window as a scarce resource — read at the right altitude, delegate bulk reconnaissance to subagents so only conclusions enter the main thread, externalize durable facts to disk, and respond to your own degradation signals. Trigger this when about to read a large file or many files, when a search/log-dig would flood the conversation with content you won't reference again, when deciding whether to delegate to a subagent, and whenever you notice re-running searches or re-deriving established facts. Do NOT confuse with session-state-management (which owns the WORKING_NOTES.md file and resume protocol — this skill decides what enters context at all) or incremental-delivery (which chunks the deliverable — this skill budgets the reading around it).
