Context Guard

Keeps requirements intact across Codex compaction, resume, and handoffs.

gerui-lv/context-guard · v0.17.2 · Development & Workflow

by Gerui LvOwner verifiedAwesome AI Plugins

Long-running Codex tasks can lose constraints after compaction or resume. Context Guard keeps a private, task-local checklist of requirements and acceptance criteria, restores open items, and only allows completion when successful evidence matches the requested result. It works alongside Codex Plan, Goal, memories, subagents, worktrees, and the transcript; it does not replace them or grant permissions. Open source, local-first, and designed to fail closed when evidence is missing or ambiguous.

Automation or dependency surfaces exist, but .github/dependabot.yml is missing.

Add Dependabot updates for GitHub Actions and dependency manifests.

The interface field "screenshots" must use HTTPS or point to a safe in-repo asset.

Update "screenshots" to use HTTPS or an existing relative asset path.

A .codexignore file helps prevent accidental inclusion of local artifacts and secrets.

Add a .codexignore file with generated assets, local state, and secret paths.

Install guidance

Install in Codex

Install through the Codex CLI plugin marketplace.

Codex plugin docs

Optional: install HOL Guard for Codex first, so it can check this plugin's tools on your machine before Codex uses them.

  1. 1

    Register the marketplace

    Run in any terminal. Codex reads the marketplace entry from .agents/plugins/marketplace.json (or the legacy .claude-plugin path) in the repository. If the repository ships none, add the generated entry from the Advanced section below first.

    shell
  2. 2

    Install the plugin

    Installs the context-guard entry from the codex-context-guard marketplace. You can also install it from the Plugins browser inside Codex.

    shell
  3. 3

    Check the marketplace is registered

    This confirms the marketplace source only. Confirm the plugin itself is enabled in the Plugins browser before relying on it.

    shell

To remove it later, run codex plugin remove context-guard@codex-context-guard.

Did setup work in Codex?

No setup reports for Codex yet. Self-reported by signed-in visitors. Copying a command is not counted, and most installs are never reported.

Attested installs: Fewer than 10 attested installs of this plugin in week 2026-W45, so no number is shown. Counted from opt-in HOL Guard install reports, once per machine and runtime, and never mixed with the answers above. How install reports work.
