Our review
Manages custom warnings (grudges) on files or packages in Matrix via slash commands.
Strengths
- Allows adding, listing, checking, and removing warnings for specific files or packages.
- Supports severity levels (info, warn, block) and repo-specific warnings.
- Direct integration with the `matrix_warn` MCP tool for centralized management.
Limitations
- Requires the `matrix_warn` MCP tool to be configured and accessible.
- Warnings are limited to the Matrix environment and do not apply to other platforms.
- Command syntax can be error-prone due to typos.
Use this skill when you want to flag problematic files or packages in your Matrix project to prevent recurring mistakes.
Do not use it for standard linting or static analysis tools, as it is designed for custom warnings, not code rules.
Security analysis
SafeThe skill only uses a single MCP tool (matrix_warn) with user-provided strings as arguments; no shell execution, file access, network calls, or obfuscated payloads. It poses no execution risk.

Matrix Warnings
Manage "personal grudges" - warnings for problematic files or packages.
Parse user arguments from the skill invocation (text after the trigger phrase).
Use the matrix_warn tool with the appropriate action parameter.
Actions
List warnings (default, or "list"):
Use matrix_warn with action: "list" to show all warnings.
- Optional:
type: "file"ortype: "package"to filter - Optional:
repoOnly: trueto show only repo-specific warnings
Add warning ("add <type> <target> <reason>"):
Use matrix_warn with action: "add" and:
- type: "file" or "package"
- target: file path/pattern or package name
- reason: why this is problematic
- severity: "info", "warn", or "block" (default: warn)
- repoSpecific: true if warning should only apply to current repo
Remove warning ("remove <target>" or "rm <target>"):
Use matrix_warn with action: "remove" and either:
- id: the warning ID to remove, or
- type + target: to remove by type and target
Check target ("check <target>"):
Use matrix_warn with action: "check" and:
- type: "file" or "package"
- target: file path or package name
Examples
/matrix:warn- list all warnings/matrix:warn add file src/legacy/*.ts "Deprecated, do not modify"/matrix:warn add package moment "Use date-fns instead"/matrix:warn remove moment/matrix:warn check .env
