Inspect or change how aggressively context-guru reduces Codex context.
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
# Choose a context-reduction preset Run `python3 ../../scripts/codex_plugin.py configure --show`. Explain the choices without selecting one for the user: `off` changes no content; `conservative` performs deterministic cleanup; `medium` adds a paid relevance-model pass; `high` adds summarization; `xhigh` adds the deepest paid sweep. Ask which one they want, then run `python3 ../../scripts/codex_plugin.py configure --preset NAME`. Run the change with `sandbox_permissions="require_escalated"`, explaining that it writes the user's context-guru configuration and restarts the local proxy. Report the emitted settings and whether the proxy restarted successfully.

How to install
mdr add rossoctl/context-guru/context-guru-preset-picker@sha256:51ba02d658f84836The line at the top of this page pins the label git:20261005.ea10fe1, 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.
