AI & ML
AI & ML agent skills cover the machine-learning workflow itself: writing and evaluating prompts, building RAG pipelines, running evals, and wiring up model APIs. Each one is a SKILL.md file your agent loads on demand, so the know-how travels across Claude Code, Cursor, and 60+ agents.
-

-
kanevry Skill Frontmatter Guard 3Injects the canonical vault frontmatter schema snippet into agent prompts before any vault-write task, preventing malformed YAML frontmatter in Obsidian notes. <example>Context: wave-executor is about to dispatch a vault-mirror agent that writes learning notes under ~/Projects/vault/40-learnings/. user: "dispatch vault-write agent" assistant: "Injecting frontmatter-guard snippet into agent prompt (vault scope detected). Required fields: id, type, created, updated. Enum type: note|daily|project|person|reference|idea|learning|session." <commentary>The wave-executor pre-dispatch hook calls detectVaultTaskScope() — the fileScope contains /Projects/vault/40-learnings/ so the guard triggers and the snippet is prepended to the agent system prompt.</commentary></example>

-
everyinc Bundle Ce Work 3Execute a plan or concrete work prompt end-to-end. Use when implementing from a plan document, a spec path, or a clear build request; use ce-debug for open-ended bugs. Use when an outer orchestrator needs implementation and local verification only, without the shipping tail.
-
peterbamuhigire Skill Skill Safety Audit 4Use when reviewing a new or changed skill package for unsafe installers, credential collection, hidden execution, unjustified privilege, or policy bypass; this read-only gate does not replace domain code review or `skill-writing` conformance work.
-
fabioc-aloha Skill Spike 3Use when the user wants to feel out an idea before committing to a real build — "spike this out", "try it", "is this even possible?", "compare A vs B". Throwaway experiments that decompose into 2-5 feasibility questions, build minimal observable prototypes, and return VALIDATED / PARTIAL / INVALIDATED verdicts. Disposable by design. Adapted from Hermes Agent / GSD.
-

Do not use for PRDs, automatic approval gates, code review batches, or auto-looped review cycles.
-
surya8991 Skill Repomix Pack 4Packs the entire codebase (or selected folders) into a single token-efficient file using repomix, so other skills can analyze the whole repo without re-reading individual files. Use when the task requires whole-codebase context: full security audits, cross-cutting refactors, architecture review, project-wide code review, or first-time onboarding to an unfamiliar repo. Auto-runs once per session at first invocation of agent-master.
-
managedcode Bundle Dotnet 4Primary router skill for broad .NET work. Classify the repo by app model and cross-cutting concern first, then switch to the narrowest matching .NET skill instead of staying at a generic layer. USE FOR: general .NET requests without a narrower framework; C# implementation, debugging, review, or refactoring; routing to framework and tooling skills. DO NOT USE FOR: unrelated stacks; tasks already covered by a narrower .NET skill. INVOKES: inspect the repository context, edit targeted files, and run relevant build, test, lint, or validation commands when changes are made.
-
managedcode Bundle Mcaf Adr Writing 4Create or update an ADR under `docs/ADR/` for architectural decisions, dependency changes, data-model changes, or cross-cutting policy shifts.

drmoisan Skill Execute Hard Lock 6Place the session in atomic execution mode bound to a specific plan-of-record. Resolves the hard-lock prompt via the drmCopilotExtension MCP tool, then delegates to the atomic-executor subagent with the resolved text. Use when a caller provides ${plan-path} and ${work-mode} and requires strict plan-following behavior.
-
drmoisan Skill Powershell QA Gate 6Final QA gate for PowerShell changes. Executes the full PoshQC format -> analyze -> test toolchain (with coverage where enforced), compares against a captured baseline, enforces zero-regression deltas, and produces the required reporting block before the agent declares the change complete.
