What it does
Architecture Guidelines is an agent skill from eser/stack. System design in eserstack: double-layered hexagonal architecture, explicit adapter composition, public API and CLI surface, request metadata, testing strategy, ADRs. Use when designing a package or service, adding options or flags, planning tests or writing an ADR. Not for file naming (use tooling-standards).
Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `evals/triggers.json`, `references/adrs.md` and `references/hexagonal-architecture.md`).
It sits in Development, covering Architecture decision records and Test strategy. It works with Deno. The repository describes itself as: The Portability Solution for Your Code! 🚀 Powered By Deno and JavaScript.
When your agent uses it
- Designing a package
- Tasks that involve Architecture decision records
- Tasks that involve Test strategy
Example prompts
- “/architecture-guidelines”
What it can do on your machine
Read from SKILL.md and the folder at commit 64939e6. 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
Architecture Guidelines loads about 516 tokens when it runs, and up to ~3.1k if it reads all its reference files. Until then it costs about 84 tokens; SKILL.md has 157 words of instructions outside code blocks.
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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 157 words (~516 tokens).
“How packages and services are structured, composed, tested and documented as decisions.”

When should I use Architecture Guidelines?
Architecture Guidelines fits situations like: designing a package; tasks that involve Architecture decision records; tasks that involve Test strategy.
How do I install Architecture Guidelines in Claude Code?
Run `npx skills add eser/stack --skill architecture-guidelines -a claude-code`. Or copy the skill folder (.agents/skills/architecture-guidelines in eser/stack) into .claude/skills/architecture-guidelines in your project. Claude Code loads it when a task matches its description.
How do I install Architecture Guidelines in Codex?
Run `npx skills add eser/stack --skill architecture-guidelines -a codex`. Or copy the skill folder (.agents/skills/architecture-guidelines in eser/stack) into .agents/skills/architecture-guidelines in your project. Codex loads it when a task matches its description.
Can I use Architecture Guidelines in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add eser/stack --skill architecture-guidelines -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/architecture-guidelines, .gemini/skills/architecture-guidelines, .github/skills/architecture-guidelines and .opencode/skills/architecture-guidelines in your project.
What does Architecture Guidelines need to run?
SKILL.md names no scripts, command-line tools or credentials: Architecture Guidelines is instructions for the agent only.
Does Architecture Guidelines access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Architecture Guidelines safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Architecture Guidelines use?
Architecture Guidelines has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Architecture Guidelines use?
About 516 tokens (SKILL.md is roughly 2.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2.6k tokens, read only when the agent opens those files.
