Debug Mantra

thananon/9arm-skills
3.9k installs3.1k stars
Summary

A debugging framework that makes Claude recite a four-step mantra at the start of every debug session, then enforce it. The steps are: reproduce reliably, trace the fail path (debugger first, then knobs, then instrumentation), falsify your hypothesis before testing it, and cross-reference every experiment against a running ledger. It triggers automatically when you mention a bug or paste an error. The discipline is rigid by design. Claude won't let you theorize without a repro, won't let you fix without knowing the fail path, and maintains a breadcrumb log to catch contradictions. Honestly, it's heavy process, but if you've ever spent two hours chasing a ghost because you skipped the boring parts, this keeps you honest.

design-systems-slds-validate

forcedotcom/sf-skills

Audit Lightning Web Components for SLDS compliance and produce a scored quality report. Runs the SLDS linter, analyzes CSS for theming hook usage and pairing, checks HTML for accessibility attributes, and scores findings across categories into an overall grade. Use when asked to "score my component", "SLDS scorecard", "quality report", "audit SLDS compliance", "how good is my SLDS", "check component quality", "rate my component", "evaluate my component", "is this component ready to ship?", "look at my LWC for issues", "audit this before I submit", "review my component before code review", or any time a user wants a quality assessment or production-readiness check on an LWC or SLDS component. Not for fixing violations (use design-systems-slds2-migrate) or building new components (use design-systems-slds-apply).

dx-code-analyzer-configure

forcedotcom/sf-skills

Set up, configure, and troubleshoot Salesforce Code Analyzer for any project. Handles installation, prerequisite checks, diagnosing broken setups, creating and editing code-analyzer.yml overrides, engine-specific settings, ignore patterns, severity overrides, and CI/CD pipeline setup. TRIGGER when: user says 'set up code analyzer', 'configure code analyzer', 'install code analyzer', 'code analyzer not working', 'fix my setup', 'scan failing', 'check my setup', 'enable/disable engine', 'exclude files', 'change severity', 'set up GitHub Actions', 'set up CI/CD', 'add to pipeline', 'pipeline fail', 'update my workflow', 'quality gate', 'fail on violations', 'scan changed files only', 'add SARIF', 'code-analyzer.yml', 'ESLint config', 'increase SFGE memory', or reports errors running Code Analyzer. DO NOT TRIGGER when: user wants to run a scan (use dx-code-analyzer-run), fix violations, explain rules, create custom rules (use dx-code-analyzer-custom-rule-create), or suppress violations.

softaworks/agent-toolkit

Interactive daily standup/meeting update generator. Use when user says 'daily', 'standup', 'scrum update', 'status update', 'what did I do yesterday', 'prepare for meeting', 'morning update', or 'team sync'. Pulls activity from GitHub, Jira, and Claude Code session history. Conducts 4-question interview (yesterday, today, blockers, discussion topics) and generates formatted Markdown update.

agentforce-architecture-analyze

forcedotcom/sf-skills

Declared architecture snapshot for one Agentforce agent: planner, topics, actions, flows, Apex, prompt templates, and NGA plugins. Renders a human-readable architecture document and Mermaid invocation graph from design-time metadata (not runtime audit rows). TRIGGER when user asks to describe, diagram, inventory, audit, document, or diff (e.g. v3 vs v5) the architecture / action tree / topic structure / tool inventory of a specific agent by agent API name in a specific org. DO NOT TRIGGER for runtime session traces, conversation transcripts, generation timings, or gateway audit chains — this skill reads design-time metadata only (use agentforce-d360-analyze for session traces).
