A Claude Code plugin marketplace. Plugins cover the full development lifecycle: release automation, design review, infrastructure verification, Home Assistant integration dev, Linux system administration, GitHub repo health, and plugin testing.
Add this marketplace to your Claude Code installation:
/plugin marketplace add L3DigitalNet/Claude-Code-PluginsOr using the full URL:
/plugin marketplace add https://github.com/L3DigitalNet/Claude-Code-Plugins.gitThen install individual plugins:
/plugin install design-assistant@l3digitalnet-pluginsAuto-update keeps plugins current automatically. To verify it's enabled:
- Run
/pluginin Claude Code - Go to the Marketplaces tab
- Select l3digitalnet-plugins
- Look for Disable auto-update (meaning it's already on)
When auto-update is enabled, Claude Code refreshes the marketplace catalog and updates installed plugins at the start of each session.
Manual update if you prefer to control when updates happen:
# Refresh the marketplace catalog
/plugin marketplace update l3digitalnet-plugins

These principles apply across all plugins in this collection. Individual plugins may define additional principles scoped to their domain.
[P1] Act on Intent: Invoking a command is consent to its implied scope. When intent is ambiguous, clarify scope before executing, not after. When intent is clear, execute without narration or confirmation of the obvious. A confirmation gate is warranted only when an operation is both truly irreversible and its scope materially exceeds what the invocation implies, not for operations that are merely large or look dangerous. If scope materially changes mid-execution, stop and re-confirm. Routine friction is a tax, not a safeguard.
[P2] Scope Fidelity: Execute the full scope of what was asked, completely, without routine sub-task confirmation gates. When a sub-task's scope is genuinely ambiguous, clarify before proceeding rather than assuming. Do not act beyond the declared scope; surface only material out-of-scope findings as notes; routine adjacent observations are not worth raising. Scope undershoot triggers additional iteration; scope overshoot violates the consent established at invocation.
[P3] Succeed Quietly, Fail Transparently: Lead with findings, not intent or preamble. Output results, not narration. Emit a compact factual summary at task completion, not after every step. On transient or infrastructure errors, retry silently. On critical failures, stop immediately and surface the complete failure (raw output included) with a recovery plan; do not attempt autonomous workarounds.
[P4] Use the Full Toolkit: When interaction is required, prefer structured choices over open-ended prompts; bound the user's decision space before presenting it. Use Claude Code's interaction primitives: bounded choices (AskUserQuestion), markdown previews for side-by-side comparisons, multi-select for non-exclusive options.
[P5] Convergence is the Contract: Iterative work defines completion as a measurable criterion (set by the plugin, the user, or collaboratively) and drives toward it without check-ins. Proceed quietly when converging normally. Surface immediately if progress stalls or regresses unexpectedly. If the cycle begins oscillating (making and undoing the same changes repeatedly), flag the pattern and stop rather than continuing. Stop only when the criterion is met, oscillation is detected, or the user intervenes.
[P6] Composable, Focused Units: Every plugin component (command, skill, hook) does one thing and is independently useful. Complex workflows emerge from combining atomic units at runtime; orchestration is assembled from the outside, not baked in.
