Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# context-window-engineer — vibes-plug Skill [English](#english) | [Bahasa Indonesia](#bahasa-indonesia) --- <a name="english"></a> ## English ### Orchestration & Integration Connects and orchestrates with `kv-cache-prefix-optimizer`, `llm-finops-router`, `frontier-ai-models-expert`, `gemini-agent-booster`, `ai-llm-integration-expert`, `vercel-ai-sdk-expert`, `adaptive-model-cascade`, `session-memory-manager`, and `deep-research-analyst` to ensure context windows are utilized efficiently across all AI-powered workflows. ### Description Production guide for engineering, partitioning, and optimizing ultra-large context windows (128k → 2M+ tokens) across frontier models. Prevents the most common failure mode in 2026 AI applications: dumping raw data into context without structure, causing degraded recall, wasted tokens, and hallucination amplification in the "lost in the middle" zone. ### Trigger Conditions Activate this skill when: - Building AI agents or applications that consume >50k tokens of context per request. - Experiencing degraded model recall, "lost in the middle" failures, or hallucinations in long-context scenarios. …

How to install
mdr add roedyrustam/vibes-plug/context-window-engineer@sha256:72c6a284d4f2edbfThe line at the top of this page pins the label v4.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
