A Claude Code skills plugin for building, running, validating, and editing AI methods (.mthds bundle files).
MTHDS is an open standard for AI methods. Find methods on the hub: MTHDS Hub. Install the reference python runtime from Pipelex.
| Skill | Description |
|---|---|
/mthds-build |
Build new AI method bundles from scratch. Supports both automated CLI build and guided 10-phase manual construction. |
/mthds-check |
Validate workflow bundles for issues. Reports problems without modifying files (read-only analysis). |
/mthds-edit |
Modify existing workflow bundles — change pipes, update prompts, rename concepts, add or remove steps. |
/mthds-explain |
Explain and document existing workflows. Walk through the execution flow in plain language. |
/mthds-fix |
Automatically fix validation errors in workflow bundles. Applies fixes and re-validates in a loop. |
/mthds-run |
Execute MTHDS methods and interpret their JSON output. Supports dry runs, mock inputs, and graph generation. |
/mthds-inputs |
Prepare inputs for workflows: placeholder templates, synthetic test data, user-provided files, or a mix. |
/mthds-install |
Install method packages from GitHub or local directories. |
/mthds-pkg |
Manage MTHDS packages — initialize, add dependencies, lock, install, update, and validate. |
/mthds-publish |
Publish methods to mthds.sh (telemetry only, no file writes). |
/mthds-share |
Share methods on social media (X, Reddit, LinkedIn). Pick specific platforms with --platform. |
