# Context Engineering Use this skill to design repo-native agent context that is portable, high-signal, and maintainable. It owns the context model, migration path, maturity assessment, and context-graph discipline across `AGENTS.md`, runtime-specific layers, specs, rules, hooks, compiled markdown knowledge bases, and related artifacts. ## Quick Reference | Task | Use | |------|-----| | Portable repo instructions | the `agents-memory` skill, [references/fast-track-guide.md](references/fast-track-guide.md) | | Spec and plan flow | [docs-ai-prd](../docs-ai-prd/SKILL.md), [dev-workflow-planning](../dev-workflow-planning/SKILL.md) | | Context graph design | [references/context-graph-guide.md](references/context-graph-guide.md), `python3 scripts/scan_context_artifacts.py --help`, `python3 scripts/validate_context_graph.py --help` | | Hot-tier staleness + supersession integrity checks | `scripts/validate_context_graph.py` (checks `check_stale_tiers`, `check_supersession_integrity`) | | Query a context graph (PPR, BFS, fan-in, tier budget) | `python3 scripts/query_context_graph.py <graph> --help` (modes: `--node`, `--impact`, `--rank`, `--ppr --seed`, `--tier-budget`) | | Compiled markdown knowledge layer | the `docs-notes-retrieval` skill, [references/context-graph-guide.md](references/context-graph-guide.md), [references/multi-repo-strategy.md](references/multi-repo-strategy.md) | | Multi-repo strategy | [references/multi-repo-strategy.md](references/multi-repo-strategy.md), [d...
