Use to diagnose and fix EvoFlow hook problems. Applies when a hook does not trigger, its matcher does not match, its script is not executable, it blocks unexpectedly, or a plugin's hooks are not enumerated. Explains EvoFlow's hook model (plugin manifest + code middlewares) and provides a step-by-step localization workflow.
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
# Diagnosing Hooks Configuration Goal: determine whether a hook issue is plugin-level (configurable) or code-level (not user-configurable). ## 1. EvoFlow hook model EvoFlow hooks come from two layers: ### A. Plugin hooks (declarative, from manifest) - Defined in the plugin manifest's `hooks` field (`.evoflow-plugin/plugin.json`) - Enumerated as metadata by `plugins/components.py` — the component type is `hook` - Hook events are listed in the manifest; the plugin must be enabled for its hooks to be active ### B. Code-level middlewares (not user-configurable) - LangChain `@hook_config` decorated middlewares in the backend code - Examples: `automation_run_guard_middleware`, `goal_auto_continue_middleware` - These control agent execution flow (jump-to model/end) and are **not configurable** by users - To change their behavior, you must modify the backend code ## 2. Common symptoms → causes → fixes ### Plugin hook not triggering 1. **Check plugin is enabled**: The plugin must be in `installed_plugins.json` with `enabledPlugins[id] != false`. 2. **Check manifest `hooks` field**: Verify the plugin's `.evoflow-plugin/plugin.json` has a `hooks` key with the expected event names. …

How to install
mdr add evovexai/evoflow/diagnosing-hooks@sha256:4f62c4ed7b9e3738The line at the top of this page pins the label git:20261016.a5d3a8b, 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.
