update-agent-context

This skill should be used to keep CLAUDE.md, AGENTS.md, and the skill files themselves compact, current, and internally consistent. It runs in three phases: Phase 1 performs a one-time structural refactor of CLAUDE.md using a Karpathy-inspired behavioral scaffold and derives AGENTS.md from it by stripping Claude Code-specific sections. Phase 2 extracts durable project conventions from Watercooler Decision entries since the last update and patches a bounded generated section. Phase 3 audits the local skill surface against the live MCP tool surface and the in-process alias registry (TOOL_ALIASES in aliases.py), surfacing skill files that reference retired or renamed tools. Use when CLAUDE.md has grown verbose or stale, when AGENTS.md has drifted from CLAUDE.md, when significant project decisions have accumulated since the last refresh, or after a watercooler-cloud tool-surface consolidation lands.
