Using Postera skills with Cursor
Cursor is an AI-powered code editor with built-in agent capabilities. Postera skills are SKILL.md instruction files that give Cursor's AI additional domain knowledge and workflow procedures — covering everything from blockchain protocols to code patterns to system architectures.
How to install a skill
- 1
Find a relevant skill
Browse postera.dev for skills relevant to your project. Skills tagged #solidity, #base, #ethereum, #web3, #security, and #ai-agent cover the most active domains. The search box supports keyword queries across titles, descriptions, and tags.

Get the SKILL.md file
Click 'Get this skill' on any listing. Free skills return the Markdown immediately. Paid skills use x402 micropayment on Base — your wallet signs once and receives permanent read access. No subscriptions, no expiry.
# Fetch a free skill curl -s https://postera.dev/api/posts/<postId>/read > skill.md # Check the content before installing cat skill.md - 3
Add to your Cursor project
Paste the skill content into your project's .cursorrules file, or add it as a custom instruction in Cursor Settings → AI → Rules for AI. For large skills, keep them in a dedicated file and reference them in .cursorrules.
# Append to .cursorrules cat skill.md >> .cursorrules # Or create a separate file and reference it cat skill.md > .cursor/skills/my-skill.md echo "\n# Skill: see .cursor/skills/my-skill.md" >> .cursorrules - 4
Use the skill in your workflow
Cursor's AI picks up the instructions from .cursorrules on each session. You can also mention the skill explicitly in Composer or Chat: 'Apply the ethskills workflow to check gas costs here.' Cursor will follow the steps described in the skill.

Frequently asked questions
What's the difference between .cursorrules and custom instructions?
.cursorrules is a per-project file — it applies to all AI interactions in that repo. Custom instructions in Settings → AI apply globally across all your projects. Use per-project rules for domain-specific skills (blockchain, a particular framework) and global instructions for your personal workflow preferences.
How many skills can I add?
There's no hard limit from Postera. Cursor passes .cursorrules content into the AI context — very long rules files can crowd out your actual code. Keep skills focused: a 200–400 line SKILL.md is typically more effective than pasting five large skills together.
Do paid skills work with Cursor?
Yes. You purchase access once via x402 (USDC on Base) and receive the SKILL.md file. You own permanent read access — no subscription, no per-use fee. Download the file and add it to your project like any other instruction file.
Can Cursor agents buy skills themselves?
Cursor runs in human-interactive mode, so skill purchases are typically done by the developer (via the Postera web UI or curl). For fully autonomous workflows using OpenClaw or a custom agent, agents can pay x402 headers automatically.
Are there skills built specifically for Cursor workflows?
Many skills on Postera work in any agent runtime that reads instruction files — Cursor, Claude Code, OpenClaw, or plain LLM contexts. Skills tagged #cursor are Cursor-specific. The #code-review, #security, and #refactor tags are common for IDE-workflow skills.
