Prevent Codex context-window exhaustion during long-running refactors, repo audits, migrations, debugging sessions, or tasks with large logs, many file reads, or repeated tool output. Use when Codex context is getting high, /compact may be needed, or the user asks for context-efficient workflows.
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
# Codex Context Guard ## Goal Keep a long Codex session useful by reducing unnecessary context growth, preserving decisions in a compact handoff, and choosing bounded next steps before the thread becomes hard to continue. ## Trigger conditions - The task has many files, logs, diffs, generated outputs, or repeated tool calls. - The user asks whether to compact, summarize, or continue in a new thread. - The agent is about to inspect broad files without a specific need. ## When to use - Use when context budget, log volume, or file-reading scope is becoming a risk. - Use before compacting a long session or moving work to another thread. ## When not to use - Do not use for short, self-contained tasks that have no context pressure. - Do not use as a substitute for actually validating completed work. ## Inputs to inspect - Current objective, recent user instructions, changed files, validation output, and unresolved blockers. - Use `git status --short` and `git diff --stat` before reading large diffs. ## Rules - Prefer targeted `rg`, `sed`, `git diff --stat`, and small file ranges over whole-file dumps. - Keep one bounded objective active at a time. …

How to install
mdr add stark-ai-de/agent-skills/codex-context-guard@sha256:0d4444b1494f30a0The line at the top of this page pins the label v0.1.0, 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.
