This skill should be used when long-running agent sessions need context compression, structured summarization, compaction, token-per-task optimization, or durable handoff summaries that preserve decisions, files, risks, and next actions.
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 Compression Strategies When agent sessions generate millions of tokens of conversation history, compression becomes mandatory. The naive approach is aggressive compression to minimize tokens per request. The correct optimization target is tokens per task: total tokens consumed to complete a task, including re-fetching costs when compression loses critical information. ## When to Activate Activate this skill when: - Agent sessions exceed context window limits - Codebases exceed context windows (5M+ token systems) - Designing conversation summarization strategies - Debugging cases where agents "forget" what files they modified - Building evaluation frameworks for compression quality - Creating durable handoff summaries that preserve decisions, files, risks, and next actions Do not activate this skill for adjacent work owned by other skills: - General token-efficiency tactics such as masking, prefix caching, or partitioning: `context-optimization`. - Diagnosing why a long context is failing before choosing a mitigation: `context-degradation`. - Writing raw outputs, logs, or plans to files without summarizing them: `filesystem-context`. …

How to install
mdr add fabioc-aloha/alex_skill_mall/context-compression@sha256:226c96859e6812afThe line at the top of this page pins the label git:20260728.80a7ab6, 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.
