Our review

Guides users through the process of creating effective Agent Skills, from gathering requirements to structuring SKILL.md files and best practices.

Strengths

  • Provides a clear file layout and frontmatter requirements.
  • Emphasizes concise, focused skills with progressive disclosure.
  • Covers multiple platform locations and team-sharing best practices.
  • Includes concrete naming conventions and description guidelines.

Limitations

  • Specific to n8n's skill naming and plugin conventions.
  • Does not cover advanced script debugging or integration testing.
  • Scope guidance is brief; tricky trade-offs get limited depth.
When to use it

Use when creating or writing a new agent skill, or when asked about skill structure, SKILL.md format, or best practices.

When not to use it

Do not use for debugging existing skills, writing actual workflow code, or for non-n8n skill systems with different conventions.

Security analysis

Safe
Quality score82/100

The skill provides guidance on creating agent skill files; it includes no executable commands beyond a harmless 'pnpm sync:skill-links' suggestion and does not instruct destructive, exfiltrating, or obfuscated actions.

No concerns found

Examples

Create a new skill
Create a new agent skill named 'extract-tables' that extracts tables from PDFs and fills forms.
Structure a SKILL.md
How should I structure my SKILL.md? Show me the frontmatter and best practices.
Team skill for Jira
I need to write a skill for our team to create Jira tickets. What should I include?

Creating skills

Skills are markdown (plus optional scripts) that teach the agent a focused workflow. Keep SKILL.md short—the context window is shared with chat, code, and other skills.

Where skills live

| Location | When to use | |----------|-------------| | .agents/skills/<name>/ | Default for n8n: team-shared, versioned, agent-neutral source. | | .claude/plugins/n8n/skills/<name>/ | Claude-specific override, or a generated symlink to .agents/skills/<name>/. | | .opencode/skills/<name>/ | OpenCode-specific override only. Shared skills stay in .agents/skills/<name>/. | | ~/.claude/skills/<name>/ | Personal skill for Claude Code across all projects. | | ~/.config/opencode/skills/<name>/ | Personal skill for OpenCode across all projects. | | ~/.cursor/skills/<name>/ | Optional personal skill for Cursor only, global to your machine. |

Do not put custom skills in ~/.cursor/skills-cursor/—that is reserved for Cursor’s built-in skills.

Prefer .agents/skills/ for anything that should match how the rest of the team works. Run pnpm sync:skill-links after adding or removing shared skills.

Before you write: gather requirements

Ask (or infer) briefly:

  1. Purpose — one concrete task or workflow.
  2. Triggers — when should the agent apply this skill?
  3. Gaps — what does the agent not already know (project rules, URLs, formats)?
  4. Outputs — templates, checklists, or strict formats?
  5. Examples — follow an existing shared skill in .agents/skills/ if one fits.

Ask the user in plain language when you need more detail.

File layout

skill-name/
├── SKILL.md       # required
├── reference.md   # optional — detail the agent reads only if needed
├── examples.md    # optional
└── scripts/       # optional

Frontmatter (required)

---
name: n8n:skill-name      # n8n:<name> — lowercase, hyphens, max 64 chars
description: >-         # max 1024 chars, non-empty — see below
  ...
---

Name — shared n8n skills use the n8n:<name> form so Claude Code namespaces them under the n8n plugin (invoked as /n8n:<name>). The <name> part must match the skill's directory name.

Description (discovery is everything — third person, WHAT + WHEN, trigger words):

  • Good: Extracts tables from PDFs and fills forms. Use when the user works with PDFs, forms, or document extraction.
  • Bad: Helps with documents or I can help you with PDFs

Authoring rules

  1. Concise — assume the model is capable; only add non-obvious domain or project facts.
  2. Progressive disclosure — essentials in SKILL.md; long reference in reference.md. Link one level deep from SKILL.md.
  3. Prefer one default — e.g. one library or one workflow; add an escape hatch only if needed.
  4. Stable wording — one term per concept; avoid dated “until month X” notes unless you tuck legacy bits behind a short “Deprecated” note.
  5. Paths — forward slashes only (scripts/foo.py).

Rough size: aim for well under ~200 lines in SKILL.md; if it grows, split detail out.

Scope: one job per skill (and parent skills)

  • Single responsibility — one primary workflow or decision tree per skill. If triggers and steps diverge a lot (e.g. “create issue” vs “create PR” vs “full ticket → PR flow”), split into smaller dedicated skills.
  • Prefer small + compose — two or three focused skills keep irrelevant detail out of context until needed. A parent (orchestrator) skill can say when to follow each child workflow and link to their SKILL.md; avoid pasting full child content into the parent.
  • When one large skill is OK — a single end-to-end flow that always runs together and shares one tight checklist;

MCPs, CLI tools, and other skills

  • Prefer CLI and repo commands when they solve the same problem — agents handle them well and they usually add less scaffolding noise to context than MCP tool discovery and schemas. Examples: gh for PRs/issues, pnpm scripts from AGENTS.md.
  • MCPs are optional per user — not everyone has the same servers enabled. If a skill requires a specific MCP to work as written, say so explicitly:
    • Put a hint in the frontmatter description (e.g. “Requires Linear MCP for …”) so mismatches are obvious early.
    • Add a short Prerequisites (or Requirements) block near the top: which integration, what it is used for, and a fallback (e.g. web UI, gh, or “ask the user to paste …”) when it is missing.
  • Referencing other skills — use the harness-visible invocation name (e.g. n8n:create-issue where namespacing is available, otherwise create-issue). For human-readable links, give the canonical path from the repo root (e.g. .agents/skills/create-issue/SKILL.md). From a sibling folder, a relative link works too: [create-issue](../create-issue/SKILL.md). Parent skills should delegate steps instead of duplicating long procedures.

Patterns (pick what fits)

  • Template — give the exact output shape (markdown/code blocks).
  • Checklist — numbered or - [ ] steps for multi-step work.
  • Branching — “If A → …; if B → …” at the top of a workflow.
  • Scripts — document run commands; say whether to execute or read the script.

Workflow: create → verify

  1. Name + description — hyphenated name; description with triggers.
  2. Outline — minimal sections; link optional files.
  3. ImplementSKILL.md first; add reference.md / scripts/ only if they save tokens or reduce errors.
  4. Check — third-person description; terminology consistent; no duplicate encyclopedic content the model already knows.

Anti-patterns

  • Verbose tutorials (“what is a PDF”) inside the skill.
  • Many equivalent options with no default.
  • Vague names (helper, utils).
  • Deep chains of linked files.
  • Assuming an MCP or tool is present without stating it or offering a fallback.
  • One oversized skill that mixes unrelated workflows instead of smaller skills + a thin parent.

Quick example stub

---
name: n8n:my-workflow
description: Does X using project convention Y. Use when the user asks for X or mentions Z.

# My workflow

1.2.## Output format

Use a fenced code block for the exact shape reviewers should see.
