Use when the user asks to author, draft, scaffold, or create a new Agent Skill or SKILL.md file. Produces a spec-compliant skill folder ready to submit or use locally with Claude.
A skill that helps you write a new skill. Given a topic, behaviour, or workflow the user wants to encode, produce a complete SKILL.md plus folder structure that follows Anthropic's Agent Skills spec exactly — and, when the target is skills.nimaaksoy.com, also satisfies that directory's extra metadata and validation rules.
The output is a working folder a contributor can drop into skills/<category>/<subcategory>/<slug>/, run npm run validate against, and submit as a PR.
When to use this skill
The user says "create a skill for X", "write a SKILL.md", "draft an agent skill", "scaffold a new skill", or similar.
The user describes a workflow, repeated prompt pattern, or behaviour they want Claude to apply automatically and asks you to turn it into a skill.
The user is contributing to skills.nimaaksoy.com and wants help authoring a submission.
The user wants to extract a reusable skill from a long-running conversation pattern.
Do not use this skill when:
The user only wants a one-off prompt or a single response — not a reusable skill.
The user is editing an existing skill (use targeted edits instead of regenerating from scratch).
The user is asking conceptual questions about how skills work — answer directly without authoring a new one.
Instructions
Work in this order. Don't skip steps — they're sequenced so the description (the part that controls whether the skill ever loads) gets written before anything else is committed.
1. Pin down the trigger
Before writing anything, get clear on the single condition that should make a model load this skill. Ask the user, in plain language:
"When should this skill activate? Describe the user's request or the situation that signals it's needed — not what the skill does, but what the user is asking for when it should fire."
If the user can't articulate a trigger in one sentence, the skill is probably too broad or not actually skill-shaped. Push back and offer to narrow it.
2. Draft the description
This is the single most important field. The model uses it to decide whether to load the skill at all.
Rules:
≤ 200 characters. Hard limit — the validator rejects anything longer.
Lead with "Use when …" or another explicit trigger phrase. A description that reads like a brochure won't trigger reliably.
Be specific about the situation. "Use when the user asks for X" beats "helps with X".
Mention the artefact produced if it's distinctive ("produces a 4-line cover letter", "outputs SQL for ClickHouse").
No marketing language ("powerful", "comprehensive", "the best way to …"). The model doesn't grade on enthusiasm.
See resources/description-examples.md for good and bad examples.
3. Pick the name
≤ 64 characters. Title Case. Short noun phrase.
The folder slug is derived from this: lowercase, kebab-case, no stop words. ("Cold Email Outreach" → cold-email-outreach.)
4. Choose category and subcategory
For submissions to skills.nimaaksoy.com, the category and subcategory must match categories.yml exactly. See resources/categories.md for the current tree.
A skill belongs to exactly one category + subcategory. If two feel equally right, pick the one closer to where a user would look for it, and add the other angle as a tag.
5. Write the frontmatter
Start from resources/template.md. Fill in:
---name:<SkillName>description:<single-linetriggerdescription,≤200chars>dependencies: [] # only if real (e.g. ["python>=3.10"])# Directory-only fields — ignored by Claude, used by the sitecategory:<category-id># must exist in categories.ymlsubcategory:<subcategory-id># must exist under that categorytags: [<1-8kebab-case>]
author:name:<AuthorName>url:<optional>github:<optional>license:CC-BY-4.0# default; only change if neededversion:0.1.0created:<YYYY-MM-DD>updated:<YYYY-MM-DD>---
If you don't know the author, ask. Don't guess — the field is required.
6. Write the body
Use these headings, in this order. The validator requires at least one ## heading; convention requires the full set:
## Overview — one paragraph: what this skill does and the situation it's built for. Written so a contributor browsing the directory understands the point in under 10 seconds.
## When to use this skill — a bullet list of trigger conditions, and (recommended) a "Do not use" sub-list.
## Instructions — step-by-step guidance for the model. Be concrete. Reference any files under resources/ by relative path.
## Examples — at least one worked example, ideally two. Use the ### Example 1 — label pattern. For each: an Input block (what the user says) and an Expected behaviour block (what the model should do).
## Resources — describe each file under resources/.
## Notes & limitations — what the skill can't do, common pitfalls, things to push back on.
## Changelog — append-only version log.
7. Add resources only if they earn it
Don't pad the folder. A resource file is worth keeping only if:
It's structured data the model needs verbatim (templates, examples, lookup tables, schema).
It's long enough that inlining it in Instructions would crowd the body.
It changes independently of the instructions (e.g. a list of supported file types).
If a "resource" is just a paragraph of text, fold it into Instructions.
8. Validate against the directory's rules
Before declaring the skill done, walk the checklist in resources/checklist.md. The site validator enforces these on every PR:
The deliverable is a folder, not just a SKILL.md. Produce:
<slug>/
SKILL.md
README.md # optional but recommended for non-trivial skills
resources/ # only if step 7 said yes
<file>
LICENSE.txt # only if not CC-BY-4.0
Then tell the user how to ship it:
# from the repo root
npm run validate # confirms it passes the same checks CI will run
git add skills/<cat>/<sub>/<slug>
git commit -m "Add <name> skill"# open a PR
Examples
Example 1 — turning a workflow into a skill
Input:
"I keep writing the same kind of bug report — title, repro steps, expected, actual, environment. Can you turn that into a skill?"
Expected behaviour:
The model should:
Confirm the trigger in one sentence: "Use when the user asks for help writing a bug report or describes a defect to file."
Propose a name: "Structured Bug Report".
Pick category: software, subcategory: qa-testing (or code-review if more fitting — confirm with user).
Draft a description ≤ 200 chars: "Use when the user describes a software defect or asks to write a bug report. Produces a structured report with title, repro steps, expected vs actual, environment, and severity."
Write Instructions that walk through the five-field structure, with a one-line rule for each.
Add a resources/template.md with the empty bug-report skeleton, since it's verbatim content the model copies.
Provide two Examples: one minimal bug, one complex bug with multiple repro steps.
Example 2 — when to push back
Input:
"Make me a skill that's good at everything coding."
Expected behaviour:
The model should not scaffold a skill. Instead it should respond:
"Skills work best when they trigger on a specific situation. 'Everything coding' is too broad — the model wouldn't know when to load it, and once loaded it would compete with general coding behaviour Claude already does well. What's the narrowest version of this? E.g. 'review a Python diff for type-safety issues', 'turn a stack trace into a 3-line root-cause hypothesis', 'write a SQL migration with rollback'. Pick one and we'll author that."
Only proceed once the user has scoped the skill to a real trigger.
Example 3 — directory submission
Input:
"Help me submit a skill to skills.nimaaksoy.com for writing investor update emails."
Expected behaviour:
The model should:
Confirm trigger and propose name (e.g. "Investor Update Email").
Look up the category — business / sales? business / finance? Likely business / finance since investor updates are a finance-team workflow; ask the user if unsure.
Produce the folder at skills/business/finance/investor-update-email/.
Write the frontmatter, body, and at least one example.
Tell the user to run npm run validate, then open a PR using the template in .github/PULL_REQUEST_TEMPLATE.md.
Resources
resources/template.md — the canonical empty SKILL.md template. Copy verbatim, then fill in.
resources/description-examples.md — good vs bad description field examples, with reasons.
resources/checklist.md — the validator's full rule list as a checkbox list. Walk it before declaring done.
resources/categories.md — flat reference of all category + subcategory ids from categories.yml.
Notes & limitations
The model decides when to load a skill based on the description alone. If the skill never triggers in practice, the description is the first thing to revise — body changes won't help.
One trigger per skill. If a skill covers two distinct triggers, split it into two skills. A single skill with "use when X or Y" tends to fire weakly on both.
Resources aren't a knowledge dump. Anything the model needs every time should be in Instructions. resources/ is for templates, examples, and reference data the model loads on demand.
Categories are project-specific. This skill's category map matches skills.nimaaksoy.com. If you're authoring for a different directory or for personal use, ignore the directory-only frontmatter fields — Claude does.
Don't author a skill for something Claude already does well. "Summarize this article" doesn't need a skill. Author a skill when the model's default behaviour is wrong, generic, or inconsistent for your specific situation.
