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.

delorenj Bundle Using N8n MCP SkillsUse when building, editing, validating, testing, or debugging an n8n workflow through the n8n-mcp MCP server — designing a flow, configuring a node, writing an expression or Code node, wiring credentials, or fixing one that misbehaves. The entry-point skill for the n8n-mcp-skills pack routes you to the right specialist skill, gives working knowledge of every n8n-mcp tool from turn one, and states the rules that keep workflows from breaking in production. Always consult it first on any n8n, workflow, node, or automation task — even a quick one-off, and even when the user names no skill — because n8n's surface drifts between versions and the specialist skills prevent silent failures.

delorenj Bundle Zellij Workspace OpsDebug, configure, and extend delorenj's single-session zellij workspace and the agent surfaces bound to it. Use when touching files in ~/.config/zellij, when a zellij CLI call hangs or times out, when deckard or zellij-driver misbehave, when agent panes come back suspended after a crash, when wiring a zellij plugin or keybind, when tab attention/notification does not reach the user, or when an agent must find/focus/rename a tab from outside a pane. Triggers: zellij, config.kdl, load_plugins, MessagePlugin, zellij pipe, zellij action, override-layout, session-layout.kdl, resurrection, start_suspended, post_command_discovery_hook, agent-pane, zellij-doctor, unwedge, Workspace session, ZELLIJ_PANE_ID, deckard, DECKARD_PLUGIN, tab attention, visual bell, zjstatus, zellij plugin wasm.

-
kevinnft Bundle PrototypeBuild a throwaway prototype to flush out a design before committing to it. Routes between two branches — a runnable terminal app for state/business-logic questions, or several radically different UI variations toggleable from one route. Use when the user wants to prototype, sanity-check a data model or state machine, mock up a UI, explore design options, or says "prototype this", "let me play with it", "try a few designs".
-
delorenj Bundle Agent Workspace LinuxUse when a task needs an isolated hidden Linux desktop or workspace-owned browser: GUI app QA, web/browser/shopping automation, sandboxed app observation, or stale workspace cleanup. Routes agent-workspace-linux MCP tools on demand. Does NOT apply to host desktop/Chrome control, generic MCP setup, or pure code/file edits.

jacob-balslev Skill Agent EngineeringUse when designing or evaluating a production AI agent system, choosing a multi-agent coordination pattern (orchestrator/worker, fan-out, consensus, sequential chain, evaluator/optimizer), diagnosing coordination failures (claim races, silent stalls, context contamination, runaway loops), or auditing whether an agent loop is truly production-ready. Covers the four pillars (architecture and lifecycle, task decomposition, coordination patterns, production reliability), the six reliability requirements (observability, cost budgets, idempotency, failure recovery, safety caps, claim locks), the delegation decision framework with overhead crossover, and the most common anti-patterns. Do NOT use for prompt wording (use `prompt-craft`), per-call tool efficiency (use `tool-call-strategy`), context-stack design within a single agent (use `context-engineering`), or runtime debugging of a deployed system (use `debugging`). Do NOT use for improve this prompt's wording to get better outputs.
-
jacob-balslev Skill Context ManagementUse when deciding what to load into an active agent session, recovering from context drift, preparing compaction or restart, distilling raw inputs into a working summary, or writing a handoff another agent can resume quickly. Covers intake triage, the active-context contract, the six-step context-management loop, working-set shaping, evidence capsules and observation masking, just-in-time handle-before-payload loading, prompt-caching alignment, context-rot defenses, drift signals and reset, the runtime-primitives boundary, compaction-ready handoffs, and selective rebuild after context loss. Do NOT use for token math (use `context-window`), prompt wording (use `prompt-craft`), persistent memory curation, or multi-graph context architecture (use `context-graph`). Do NOT use for calculate the per-zone token budget for the 200K context window. Do NOT use for improve this prompt template for the grader. Do NOT use for curate the persistent memory index file.

-
jacob-balslev Skill No Cutting CornersEnforce five non-negotiable quality pillars as a pre-output gate: complete reporting (show ALL items, never filter unilaterally), verification (no claim of works/done/exists without a tool-call receipt in the same turn), thoroughness (every acceptance criterion verified with evidence; docs ship with the change), enrichment ('improve' adds capability, never trims), and anti-shortcut (exhaust deterministic lookup before guessing; findings demand action, not filing). Use when reviewing enumerated output for completeness, when an agent claims something works without evidence, when marking a task done, or when asked to 'improve' anything.
-
jacob-balslev Skill Research SynthesisUse when turning raw qualitative research output (interview transcripts, field notes, diary entries, observation logs) into themes, patterns, insight statements, and design-ready artifacts via affinity mapping, empathy maps, and jobs-to-be-done framing. Do NOT use for collecting new research, quantitative analysis, statistical inference, or summarizing a single document — synthesis specifically operates on a corpus of qualitative evidence. Do NOT use for Run more interviews with five additional participants. Do NOT use for Calculate the response rate of the survey. Do NOT use for Summarize this single PDF document. Do NOT use for transforming a corpus of collected qualitative evidence into themes and insights (use user-research).
-
jacob-balslev Skill Tool Call StrategyUse when an agent is making too many tool calls, when context is filling from verbose tool outputs, when the same operation could be a script instead of N individual calls, or when designing a tool-use protocol for a new agent or harness. Covers the three costs of every call (token, latency, context pollution), the script-vs-call decision gate, tool-selection decision trees (file-search vs content-search vs targeted-read vs full-read), call batching and parallelization, redundancy avoidance, the poka-yoke principle, subagent delegation for context protection, and cost-benchmark heuristics by task type. Do NOT use for prompt wording (use `prompt-craft`), broader context stack design across the five layers (use `context-engineering`), runtime tool failures or production debugging (use `debugging`), or behaviour-preserving refactor mechanics (use `refactor`). Do NOT use for improve this prompt's wording to get better outputs. Do NOT use for design what skills get loaded for which prompts.
-
jacob-balslev Skill Context EngineeringUse when designing what information reaches an LLM agent before it reasons — system prompt, persistent memory, always-loaded rules, injected skills, and the user prompt — or when diagnosing why an agent produced a wrong answer despite a clear instruction. Covers the four context failure modes (missing, stale, wrong, overwhelming), the five-layer context stack, four context quality metrics (injection precision and recall, utilization, freshness), the Frequent Intentional Compaction (FIC) protocol, subagent delegation for context-heavy work, and the failure-mode decision tree. Do NOT use for prompt wording (use `prompt-craft`), authoring a new SKILL.md (use `skill-scaffold`), or deciding which skill the router activates for a given query (use `skill-router`). Do NOT use for improve this prompt's wording to get better outputs. Do NOT use for scaffold a new SKILL.md for our team's deploy procedure. Do NOT use for the router picked the wrong skill for this query — debug it.
-
jacob-balslev Skill Epistemic GroundingUse when authoring any artifact that makes claims — skill content, documentation, audit findings, architecture proposals, code review comments, research summaries, or agent output. Covers the discipline of grounding every claim to a verifiable source, distinguishing verified-by-evidence from inferred-from-context, Chain-of-Verification-style claim checking, RFC 2119/RFC 8174 modality, Toulmin argument structure, citation faithfulness, native citation-tool limits, and honest handling of inference, absence, conflict, and currentness. Do NOT use for execution-level evidence protocols or output-completeness enforcement (use methodology), naming precision (use semantics), or grader/rubric design (use evaluation or eval-driven-development). Do NOT use for decide which lint rule to add for a specific kind of drift (use skill-infrastructure). Do NOT use for evaluate a finished SKILL.md against the comprehension grader (use evaluation).
