Use when deciding whether to compact agent context -- the window is filling up, you are about to switch from one phase to another (research, planning, implementation, debugging), a failed approach left dead-end reasoning, or a previous mid-task compaction lost critical state.

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

## Purpose

Compact at logical boundaries to preserve high-value context while clearing noise. Arbitrary or mid-task compaction loses critical state -- file paths, variable names, partial reasoning -- that is expensive to reconstruct.

## When to Use

- The context window is filling and you are at a phase boundary (research, planning, implementation, debugging)
- A failed approach left dead-end reasoning that pollutes the next attempt
- You are starting a conceptually distinct task in the same session
- A prior mid-task compaction dropped state you then had to rebuild

## Inputs

- The current session state and which phase transition is approaching
- Knowledge of what is already saved durably (task list, files, git, memory) versus only in conversation

## Workflow

1. **Decide whether to compact by transition.** Use the boundary table; default to NOT compacting mid-work.

   | Transition | Compact? | Reason |
   | --- | --- | --- |
   | Research -- Planning | Yes | Research context is bulky; the plan is the distilled output |
   | Planning -- Implementation | Yes | Plan is saved in tasks/files; context is free to reset |

How to install

The exact contents, by fingerprint
mdr add yeaight7/agent-powerups/strategic-context-compaction@sha256:3e3293f948599bff

The line at the top of this page pins the label git:20260606.c168b1f, 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.
