What it does
North Star is an agent skill from udecode/plate. Constitutional source of truth for reusable Plate architecture and public API design. Use when introducing or changing reusable public APIs, runtime/service boundaries, builder or factory patterns, extension registration contracts, naming/layering rules, or performance-sensitive architecture.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files (for example `rules/anti-patterns.md`, `rules/decision-ladder.md` and `rules/laws.md`).
It sits in Backend & APIs, covering Microservices and API design. The repository describes itself as: Rich-text editor with AI and shadcn/ui.
When your agent uses it
- Changing reusable public APIs
- Runtime/service boundaries
- Factory patterns
- Extension registration contracts
Example prompts
- “/north-star”

What it can do on your machine
Read from SKILL.md and the folder at commit 6f3815d. 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
North Star loads about 1.9k tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 789 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 789 words (~1,860 tokens).
