README (SKILL.md)
Filter
Filter is a rule-based skill for reducing noise and preserving signal.
It helps create and manage reusable filter rules for:
- news
- search results
- structured task streams
- JSON-like data
What this skill does
- creates filter rules
- stores reusable rules locally
- supports priority-based filtering
- supports allowlists and blocklists
- prepares rule sets for future filtering workflows
Best use cases
- email triage
- news feed cleanup
- search result cleanup
- task stream narrowing
- structured data filtering
Inputs
- content type
- filter criteria
- priority level
Output
- saved filter rule
- reusable local rule set
- rule summary
Usage Guidance
This skill appears to do exactly what it says: create and store reusable filter rules locally. Before installing, note that it will create and overwrite ~/.openclaw/workspace/memory/filter/rules.json (ensure you have backups if you already use that path). The stored rules are plaintext JSON — avoid placing sensitive secrets inside rule criteria. There are no network calls or credential requests in the provided code, so external exfiltration is not indicated. If you are concerned about filesystem safety, run the script in a sandbox or inspect/verify the file path permissions (to avoid unexpected symlink or permission issues) before granting the agent broad automation rights.
Capability Analysis
Type: OpenClaw Skill
Name: filter
Version: 1.1.0
The skill is a straightforward utility for creating and managing filter rules stored in a local JSON file. The Python script (scripts/create_filter.py) uses standard libraries to handle file I/O and command-line arguments without any network activity, obfuscation, or risky execution patterns.
Capability Assessment
Purpose & Capability
Name/description match the included files and script. Requiring python3 and a config path under ~/.openclaw/workspace/memory/filter for storing rules is appropriate and expected for a local rule-storage tool.
Instruction Scope
SKILL.md and the included create_filter.py only describe/perform creating and saving filter rules. The instructions and script only read/write the declared rules.json path and do not reference other files, environment variables, or external endpoints.
Install Mechanism
No install spec; the skill is instruction-only with a small included Python script that uses only the standard library. Nothing is downloaded or written outside the user's OpenClaw workspace.
Credentials
The skill requests no credentials or environment variables. The only declared resource is a local config path for rules storage, which is proportional to the functionality.
Persistence & Privilege
always is false and the skill does not modify other skills or global agent configuration. It creates/updates a local rules.json file in the user's OpenClaw workspace, which is an appropriate scope for persistence.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install filter - After installation, invoke the skill by name or use
/filter - Provide required inputs per the skill's parameter spec and get structured output
