Free skills 11

Start here. No account, no charge. Read-only or preview-before-write.

Env Doctor

Free

Fix the "it works on my machine" problem before you touch the code.

Env Example Generator

Free

Turn a .env into a safe .env.example you can commit. Keeps every key, strips every value, preserves comments and order, and flags the secret-looking keys.

Git Commit Writer

Free

Generate Conventional Commit messages from your staged git diff.

Lead Enricher

Free

Turn a company URL or name into a B2B lead profile.

License Picker

Free

Generate a ready-to-use LICENSE file for your repo. Pick from MIT, Apache-2.0, GPL-3.0, MPL-2.0, BSD-2-Clause, BSD-3-Clause, or The Unlicense, fill in your name and year, and get the canonical text.

Markdown Table Formatter

Free

Align messy Markdown tables so the source is readable, or build a clean table from pasted CSV. Changes spacing only, never the cell content.

Outreach Writer

Free

Turn a lead profile and a trigger event into a cold email worth sending.

Pipeline Reporter

Free

Turn a messy CRM CSV export into a clean sales pipeline report.

README Generator

Free

Generate a README from your actual repo, not a hallucinated guess.

Robots Sitemap Validator

Free

Check your robots.txt and sitemap.xml for the mistakes that quietly block crawlers, and never touch the live site.

TODO FIXME Extractor

Free

List every TODO, FIXME, HACK, XXX, BUG, and OPTIMIZE comment in your codebase with file, line, and tag, grouped with counts. A clean tech-debt inventory instead of scrolling grep output.

Agent-native and reliability 20

For the files, contracts, and failure modes your AI assistant actually touches.

GuardrailDoctor

Penetration-test your coding agent's guardrails before you ship.

MCP Server Starter & Safety Kit

Scaffold and audit secure MCP servers with input schemas, confirmation gates, and safety-first tool definitions.

AI Code Verification Gate

Stop your agent from claiming done before it is proven.

Model Migration Checker

Find the model-version coupling that breaks when you move to a new model: hardcoded names, renamed parameters, token-limit assumptions, response-format and tool-schema coupling, and hardcoded cost constants.

Reference Grounding Checker

Before an agent acts on a plan, verify that the things it named actually exist.

Skill Injection Scanner

Scan a SKILL.md package for prompt injection and secret exfiltration before you install or publish an agent skill. Most malicious instructions hide in the natural-language prose, not the code.

uBrowser

Drive a browser from your agent without the token bloat.

Model Inventory Auditor

Inventory every LLM model and provider your code depends on, the AI bill of materials, and flag the concentration risk. When a model can be pulled offline overnight, you cannot manage a risk you cannot see.

AGENTS.md Linter

Lint your AGENTS.md, the cross-tool standard for agent instructions, for the problems that make a coding agent misbehave. Also works on CLAUDE.md and .cursorrules.

Dangerous Command Linter

Flag the destructive operations in a shell command or script before anyone runs it.

Guardrail Fallback Linter

Find the LLM calls that break when a model blocks a response or falls back to another model.

LLM Cost Leak Linter

Find the code that quietly runs up your LLM bill.

llms.txt Doctor

Generate an llms.txt for your site and validate an existing one against the spec. llms.txt is the emerging standard for telling models and agents which parts of your site to read.

Meeting Action Item Verifier

Pull the real commitments out of a meeting transcript, with owners, and separate firm action items from tentative let-us-revisit ones. It never invents an owner.

Model Resilience Linter

Find the LLM integration code that will not survive a provider being pulled or going down. This is about the model disappearing, not the model declining a request.

Model Risk Register Generator

Generate the model and vendor risk register a security lead asks for the morning after a model gets switched off. Built from your real dependencies, focused on availability and continuity.

OpenClaw Guardrail Linter

Scan your OpenClaw config for the settings that quietly hand your agent too much power.

Prompt Template Linter

Lint a prompt template for the issues that cause injection and flaky output. It detects problems; it does not write prompts.

Skill Listing Auditor

Audit Agensi skill packages for marketplace readiness, formatting compliance, and safety pre-checks.

Tool Schema Linter

Lint the function-calling tool definitions your agent exposes, so it picks the right tool instead of the wrong one or none.

Security and safety 10

Catch the mistakes that leak data or let an agent off its leash.

Developer tools and DevOps 27

The checks and generators that keep a codebase and a pipeline honest.

Codebase Graph

Map any repo into an interactive D3 dependency graph plus a Markdown onboarding guide.

Launch Planner Pro

Generate a complete 30/60/90 day product launch plan.

GitHub Actions Permission Hardener

Audit and harden GitHub Actions workflows against overbroad permissions, secrets exposure, and supply-chain risks.

HandoffPilot

Save a coding agent's working state before it hits the context limit, then resume on any model. New in v2.0: Recovery Mode rebuilds a handoff from a transcript and your repo even when a session was cut off with nothing saved.

n8n Workflow QA Linter

Lint an exported n8n workflow before it ships.

Spec2Code

Turn messy PRDs, Notion docs, and user stories into a structured implementation plan.

a11y Regression Test Generator

Generate runnable accessibility regression tests, not just a findings report.

dbt Test & Quality Auditor

Audit your dbt project for the test and documentation gaps that let bad data ship.

Docker Compose Stack Doctor

Diagnose why your Docker Compose stack will not come up.

Test Quality Auditor

Find the unit tests that pass without testing anything. Coverage numbers lie when the tests are tautological, and AI test generators produce exactly that.

Vercel Build Log Doctor

Figure out why your Vercel build or deploy failed without scrolling the whole log.

Webapp Tester

Run real Playwright E2E tests on your web app.

Change Impact Mapper

Map the blast radius of a code change before you run the whole suite.

Doc Drift Detector

Catch documentation that drifted from your code: functions, CLI flags, and env vars named in your docs that are gone from the source.

Ad Copy Policy Linter

Check ad copy for the editorial issues that get Google and Meta ads disapproved, before you submit.

Bus Factor Report

Find where knowledge is dangerously concentrated in a codebase. From your git history it flags the files only one person has ever touched and the authors who own too much, and estimates the truck factor.

CI Doctor

Debug failing GitHub Actions without scrolling 10,000 log lines.

i18n Completeness Auditor

Audit a JavaScript or TypeScript frontend for missing translations and hardcoded UI strings before you ship a new locale.

OpenAPI Contract Guard

Lint an OpenAPI spec and diff two versions to catch breaking API changes before they reach consumers.

Perf Budget Auditor

Audit your frontend build against a performance budget and catch size regressions before you ship.

Changelog Generator

Turn git history into clean release notes.

Launch Readiness Checklist Generator

Generate a personalized before-you-ship checklist for your app, with the things you have already done pre-checked. Pick your app type and it tailors the list and scans your repo for what is in place.

Repo Card

Generate a shareable stat card for any repo, with an honest health grade: language mix, size, whether tests, docs, and a license are present, and an A-to-F grade.

Branch Name Generator

Turn a messy task description into a clean, conventional git branch name.

Code Comment Cleaner

Find and remove commented-out dead code across 8 languages (JS, TS, Python, Java, Go, Rust, HTML, CSS) while preserving TODOs, FIXMEs, license headers, disabled tests, and real documentation.

Git Stash Helper

Save, name, list, and restore git stashes without losing track of what is in them.

PR Template Generator

Generate a complete pull request description from your staged changes, commits, and branch diff.

Brand, social, and writing 11

Presence tools and anti-slop. Protect the name, fix the tells.

Localization QA Auditor

Run structural QA on your translation files across locales: placeholder mismatches, untranslated strings, length overflow, terminology drift, and missing keys. It checks form, not meaning, so you do not need to speak the language.

Voice Bible

Audit a draft against your own voice spec and flag every line that breaks your house style. You define the rules once; it enforces them everywhere.

AI Tell Detector

Scan a draft for the tells that make writing read as AI-generated, so you can revise them in your own voice before publishing.

Brand Consistency Linter

Hold your bios, footers, and profiles to one brand spec, so the misspelled name and the stale tagline never ship.

Open Graph Social Card Auditor

Check supplied HTML for missing share metadata, relative image URLs, SVG portability risk, and a common image-dimension preset. Local and read-only.

Handle Rules Linter

Check a desired handle against every platform's username rules and find the form that works everywhere. X caps at 15, YouTube and TikTok reject periods, and you usually find out one platform at a time.

VoiceLock

Humanize AI writing without changing the facts.

Confusable Handle Detector

Flag the hidden and look-alike characters lurking in a handle or brand string: the spoofing tricks and display bugs you cannot catch by reading.

Em Dash Cliche Stripper

Flag every em-dash and AI transition cliche in a draft and get a plain replacement suggestion for each.

QR Payload Auditor

Check the exact decoded QR payload for incomplete URLs, listed shorteners, unsafe schemes, narrow format problems, and explicit credential-like fields.

Typo Hunter

Catch typos, homophones, and near-miss misspellings across code, docs, and markdown, in a commit, your staged changes, a file, or a whole directory.

Sales and CRM 12

Turn raw CRM data and lead lists into something a rep can act on.
