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 yaklang on GitHub. Read the source before you install it.

Installation

Install the Api Recon And Docs 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/yaklang/hack-skills.git /tmp/hack-skills
mkdir -p .claude/skills
cp -r /tmp/hack-skills/skills/api-recon-and-docs .claude/skills/api-recon-and-docs

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

Use it in TypingMind

Enable Api Recon And Docs 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 Api Recon And Docs 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 Api Recon And Docs 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.

SKILL: API Recon and Docs — Endpoints, Schemas, and Version Surface

AI LOAD INSTRUCTION: Use this skill first when the target is a REST, mobile, or GraphQL API and you need to enumerate endpoints, documentation, versions, and hidden surface area before exploitation.

1. PRIMARY GOALS

Discover all reachable API entrypoints.
Extract schemas, optional fields, and role differences.
Identify old versions, mobile paths, GraphQL endpoints, and undocumented parameters.

2. RECON CHECKLIST

JavaScript and client mining

bash
curl https://target/app.js | grep -oE '(/api|/rest|/graphql)[^"'\'' ]+' | sort -u

Common documentation and schema paths

text
/swagger.json
/openapi.json
/api-docs
/docs
/.well-known/
/graphql
/gql

Version and product drift

text
/api/v1/
/api/v2/
/api/mobile/v1/
/legacy/

3. WHAT TO EXTRACT FROM DOCS

optional and undocumented fields
admin-only request examples
deprecated endpoints that may still be active
schema hints like additionalProperties: true
parameter names tied to filtering, sorting, IDs, roles, or tenancy

4. NEXT ROUTING

object IDs everywhere	api authorization and bola
JWT, OAuth, role claims	api auth and jwt abuse
GraphQL or hidden fields	graphql and hidden parameters

Frequently asked questions

What does the Api Recon And Docs AI skill do?

API reconnaissance and documentation review playbook. Use when discovering endpoints, schemas, versions, OpenAPI specs, hidden docs, and surface area for API testing.

Why use Api Recon And Docs on TypingMind?

Because you install it once and use it with any model. Api Recon And Docs 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 Api Recon And Docs in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/yaklang/hack-skills/tree/main/skills/api-recon-and-docs. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Api Recon And Docs?

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 Api Recon And Docs?

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

Is the Api Recon And Docs AI skill free?

Yes. It is published on GitHub by yaklang 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.
