-
dojogenesis Skill Health Audit 3Conduct a comprehensive 4-phase health audit on any software repository. Evaluates 5 dimensions (critical issues, security, testing, technical debt, documentation) with GREEN/YELLOW/RED classification, generates actionable engineering tasks with file paths and effort estimates, and produces a permanent dated audit artifact. Use when onboarding to a new codebase, after major releases, on a recurring schedule, or whenever a project feels at risk. Trigger words: health check, audit, code review, technical debt, security review, project health, sustainability, code quality.

dojogenesis Skill Documentation Audit 3Systematic process for auditing project documentation to detect and correct drift -- the gap between what docs say and what the code actually does. Cross-references every document against the actual codebase to classify findings as Accurate, Drifted, Missing, or Orphaned. Use when documentation feels stale, after major releases, before onboarding new contributors, or on a recurring schedule. Trigger words: documentation drift, outdated docs, stale README, docs audit, missing documentation, broken links, doc review.

-
drmoisan Skill Remediation Handoff Atomic Planner 8Reusable remediation trigger and atomic_planner handoff steps. Use when audits require remediation inputs and a delegated remediation plan.
-
dailybothq Bundle Deepworkplan Verify 4Verify that a repository is DeepWorkPlan-conformant (AI-first) and that its plans are well-formed, producing an objective pass/fail report. Use when the developer asks to verify, audit, or check conformance of a repo or a plan.
-
octanejs Bundle Update Bindings 4Audit one, several, or all existing Octane bindings; implement selected maintenance findings or remove redundant copied files with evidence matched to source ownership. Use for binding updates, lifecycle fixes, dependency or metadata maintenance, and convenience-import requests.
-
octanejs Skill Performance Audit 4Audit or defend Octane performance. Use when a change can affect per-render, per-node, compiler-output, SSR, hydration, or bundle cost, or when asked whether something is fast enough.
-
webmaxru Bundle Github Agentic Workflows 4Authors, reviews, installs, and debugs GitHub Agentic Workflows in repositories, including workflow markdown, frontmatter, gh aw compile and run flows, safe outputs, security guardrails, and operational patterns. Use when creating or maintaining GH-AW automation. Don't use for standard deterministic GitHub Actions YAML, generic CI pipelines, or non-GitHub automation systems.
-
dtsong Skill Data Classification 3Use when classifying data elements by sensitivity tier and defining per-tier handling requirements. Covers data inventory, sensitivity classification, PII flow mapping, encryption and masking specifications, and cross-boundary transfer documentation. Do not use for regulatory gap analysis (use compliance-review) or audit logging design (use audit-trail-design).
