Hex Reference Architecture

What it does

When your agent uses it

• Designing new Hex integrations
• Reviewing project structure
• Establishing architecture standards for Hex applications
• With phrases like hex architecture

Example prompts

• “hex architecture”
• “hex best practices”
• “hex project structure”
• “/hex-reference-architecture”

Requirements

• Compatibility (from SKILL.md): Designed for Claude Code
• Pre-approved tools (allowed-tools): Read, Grep

Workflow steps

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

1. 1Map every trigger-to-project edge with owner, data class, allowed parameters, authorization scope, retry behavior, observability, and…
2. 2Start with a sandbox project and fail closed on unknown project, parameter schema, destination, or response shape.
3. 3Make asynchronous execution idempotent and bounded; quarantine uncertainty rather than resubmitting or exporting output for debugging.
4. 4Canary one project with aggregate signals before promotion and retain the prior revision.
5. 5Re-evaluate controls whenever credentials, project ownership, schedules, or parameters change.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Grep

  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

  Links to these hosts (documentation or services it may open):

  • learn.hex.tech
  • github.com
  • hex.tech

  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.

• Compatibility

  Designed for Claude Code

  From compatibility in the SKILL.md frontmatter.

Context cost

Hex Reference Architecture loads about 1k tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 244 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~90

When it runs · the whole SKILL.md, loaded when a task matches

~1k

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

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.

description

Implement Hex reference architecture with best-practice project layout. Use when designing new Hex integrations, reviewing project structure, or establishing architecture standards for Hex applications. Trigger with phrases like "hex architecture", "hex best practices", "hex project structure", "how to organize hex", "hex layout".
