enforce-first

Apply the F.I.R.S.T test quality rubric (per CONVENTIONS.md §Tests) to a test suite or individual tests. Use when develop-tdd is writing tests, when test quality needs to be checked, or when user mentions F.I.R.S.T or "test quality".

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by danielvm-git on GitHub. Read the source before you install it.

Installation

Install the Enforce First AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/danielvm-git/bigpowers.git /tmp/bigpowers
mkdir -p .claude/skills
cp -r /tmp/bigpowers/skills/enforce-first .claude/skills/enforce-first

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Enforce First in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Enforce First on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Enforce First is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Enforce FIRST

HARD GATE — HARD GATE — Before shipping, ALL enforcement checks must pass: lint, typecheck, tests, coverage gates. Do NOT disable or skip checks to get to green.

Apply the F.I.R.S.T rubric per CONVENTIONS.md §Tests to evaluate and improve tests.

This skill is typically invoked internally by develop-tdd during the test-writing phase. It can also be run standalone on an existing test suite.

Modes

Default: full F.I.R.S.T audit (all 5 criteria)
--quick: Check Fast, Independent, and Self-Validating criteria only (per CONVENTIONS.md §Tests). Used by build-epic step 6 as a mechanical gate after audit-code. Skips Repeatable and Timely which require contextual judgment.

The F.I.R.S.T Rubric

See CONVENTIONS.md §Tests for the canonical F.I.R.S.T rubric definition, checklists, and fix patterns.

Mechanical self-check (runs before reporting audit complete):

bash
grep -q '## Tests (F.I.R.S.T' CONVENTIONS.md
grep -qE 'Fast|Independent|Repeatable|Self-Validating|Timely' CONVENTIONS.md

Each criterion must be explicitly addressed in the audit report with pass/fail per test file reviewed.

Applying the rubric

For each failing criterion:

Identify which tests violate it
Describe the fix
Apply the fix
Re-run the suite to confirm it still passes

Report: "F.I.R.S.T audit complete. X criteria passed, Y fixed."

Verify

→ verify: grep -q '## Tests (F.I.R.S.T' CONVENTIONS.md && grep -qE 'Self-Validating|Repeatable' skills/enforce-first/SKILL.md && echo OK

Frequently asked questions

What does the Enforce First AI skill do?

Why use Enforce First on TypingMind?

Because you install it once and use it with any model. Enforce First is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Enforce First in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/danielvm-git/bigpowers/tree/main/skills/enforce-first. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Enforce First?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Enforce First?

As many as you like. As long as a model supports skills, you can use Enforce First with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Enforce First AI skill free?

Yes. It is published on GitHub by danielvm-git under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
