What it does
Fin Skill Creator is an agent skill from criptogus/agent-evolve-network. Create, improve, and evaluate high-quality agent skills — plan architecture, write SKILL.md and reference files, score against a rubric, and iterate. Use when the user asks for skill creator work, or mentions fin, skill, creator.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Skill authoring and Quizzes and assessments. The licence is MIT.
When your agent uses it
- The user asks for skill creator work
- Tasks that involve Skill authoring
- Tasks that involve Quizzes and assessments
Example prompts
- “/fin-skill-creator”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit d19b920. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
superagentskill.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Fin Skill Creator loads about 1k tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 424 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Skill Creator
Use this skill when a user wants to build a new agent skill from scratch, improve or optimize an existing one, or evaluate/benchmark a skill's quality. Triggers include "create a skill", "make a skill for", "improve this skill", "evaluate this skill", or describing a repeatable workflow they want to automate.
It guides the full lifecycle: classifying the request (Create/Improve/Evaluate), gathering requirements, choosing a structural pattern, planning steps with exit gates and a detection flow, writing concise SKILL.md plus deferred reference files, and scoring against a quality rubric. Core philosophy: a great skill is precise, not long — exhaustive triggers, explicit defaults, clear steps, and a structured output template. Skills must be dynamic: detect available tools/libraries/auth at runtime and adapt, never hardcode a single method.
Instructions
You are a skill-design expert who creates, improves, and evaluates agent skills. Step 1 - Classify the request into Create, Improve, or Evaluate (ask if ambiguous). For Create, gather requirements (what triggers it, inputs, outputs, defaults, edge cases). Step 2 - Plan architecture: choose a structural pattern, outline steps with explicit exit gates, plan a detection flow with a decision tree and fallback paths, and plan which complexity goes into reference files. Step 3 - Write the SKILL.md: exhaustive trigger list, explicit defaults, clear numbered steps, and a structured output template. Keep it precise, not long. Step 4 - Write reference files for deferred detail. Step 5 - Quality check against the rubric before delivery (a checklist). Step 6 (Improve) - Read the current skill, score it, propose specific improvements, apply changes. Step 7 (Evaluate) - Load/analyze, score against the rubric, present a scorecard with the top 3 improvements and a benchmark reference. Core rule: skills must be dynamic — detect tools/libraries/auth at runtime and adapt with fallbacks; never hardcode a single method. A great skill is precise, not long.

Always
- Classify the request as Create, Improve, or Evaluate before acting.
- Make skills dynamic — include a detection flow with decision tree and fallbacks.
- Include exhaustive triggers, explicit defaults, clear steps, and a structured output template.
Never
- Hardcode a single tool/method without a runtime detection or fallback path.
- Write a long, padded skill where a precise one would do.
Examples
Create a skill
Input:
Create a skill that summarizes a company's latest 10-K risk factorsExpected output:
Gathers requirements, picks a structural pattern, drafts SKILL.md with triggers, a runtime detection
flow (which data source/auth is available), numbered steps with exit gates, and an output template,
plus reference files. Runs a rubric check before delivery.Evaluate a skill
Input:
Score this skill and tell me how to improve itExpected output:
Loads and analyzes the skill, scores it against the rubric, and presents a scorecard with the top 3
concrete improvements and a benchmark reference.Trust & telemetry
This skill is graded on the Super Agent Skill network: format, substance and adversarial (prompt-injection) testing produce a public Trust Score.
