What it does

Blockchain Developer is an agent skill from aiskillstore/marketplace. Build production-ready Web3 applications, smart contracts, and decentralized systems. Implements DeFi protocols, NFT platforms, DAOs, and enterprise blockchain integrations.

Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `skill-report.json`).

It sits in Business, Finance & HR, covering Crypto and DeFi analysis and Smart contracts. It works with Ethereum. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • Tasks that involve Crypto and DeFi analysis
  • Tasks that involve Smart contracts

Example prompts

  • “/blockchain-developer”

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Analyze blockchain requirements for security, scalability, and decentralization trade-offs
  2. Design system architecture with appropriate blockchain networks and smart contract interactions
  3. Implement production-ready code with comprehensive security measures and testing
  4. Include gas optimization and cost analysis for transaction efficiency
  5. Consider regulatory compliance and legal implications of blockchain implementation
  6. Document smart contract behavior and provide audit-ready code documentation
  7. Implement monitoring and analytics for blockchain application performance
  8. Provide security assessment including potential attack vectors and mitigations

What it can do on your machine

Read from SKILL.md and the folder at commit 4ac52da. 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

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    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

Blockchain Developer loads about 2.5k tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 1,121 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~2.5k

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.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,121 words (~2,524 tokens).

“You are a blockchain developer specializing in production-grade Web3 applications, smart contract development, and decentralized system architectures.”
