What it does
Declare Types is an agent skill from one-ie/one. Give this workspace a resource type — products, lessons, tickets, whatever the business actually tracks — by writing one TOML file, so navigation, a searchable index, a detail page and a create/edit form all appear without code.
Its SKILL.md is about 940 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design. It works with React, Astro and shadcn/ui. The repository describes itself as: Make Your Ideas Real. Build Apps, Websites and AI Agents with Plain English with Astro, React, Shadcn and Cloudflare.
When your agent uses it
- Frontend & Design work in your project
Example prompts
- “/declare-types”
What it can do on your machine
Read from SKILL.md and the folder at commit 42ba8cd. 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 (its code samples are toml).
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
Declare Types loads about 939 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 515 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 515 words (~939 tokens).
“A type is a TOML file in data/types/. one push sends every one of them to world:declare-types, and the console generates the admin from the manifest — a sidebar entry, an index table with search and inline cell editing, a…”
