i-insist

Block agent tool calls with checks from your plugins or your own scripts. Works with Codex and Claude Code. When a check blocks an action, the agent sees the reason and stops. Say I insist when you want to override it.

Install

Requires uv, Python 3.12 or newer, and Linux or macOS.

uv tool install 'git+https://github.com/crypdick/i-insist@main'
i-insist install codex
i-insist install claude

Install only the integrations you use. Restart the agent and check hook trust with /hooks.

Rules

Plugins supply their own checks. Rules live in ~/.i-insist/*.toml for global use or .i-insist/*.toml within a project. Global and applicable local rules run together.

Installation includes a rule requiring human approval to change .i-insist files. Other checks come from your plugins or scripts.

To write your own, start with the runnable example and rule and checker reference. Plugin installers replace their generated registrations, so don't edit those files to customize a plugin.

Human overrides

Include I insist anywhere in your message, in any capitalization:

I insist, update both protected files.

Approval lasts for the current response and resets with your next message or when you start or resume a session. Quoted text and code blocks count too.

Rules marked overridable = false still run. Invalid configuration still blocks approved calls. Approval doesn't override other plugins or the agent's own permissions.

These are cooperative guards, not a sandbox. They depend on the agent calling hooks, and checkers run with your account's privileges.

Update or uninstall

Update the runner, then repeat the install command for each integration you use if the update changes hook registrations:

uv tool upgrade i-insist

To uninstall, remove each integration you installed before removing the runner:

i-insist uninstall codex
i-insist uninstall claude
uv tool uninstall i-insist

Uninstall leaves provider rules and approval caches in place.
