What it does
Migrate TS Decorator SDK is an agent skill from golemcloud/golem. Migrating a TypeScript Golem agent from the removed decorator/base API (@agent + BaseAgent) to the current schema-driven defineAgent API. Use when porting an existing decorator-based TS agent, when you see @agent()/extends BaseAgent/@endpoint/@description code that no longer compiles, or when asked to modernize a TS component to the current SDK.
Its SKILL.md is about 3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with TypeScript. The repository describes itself as: Golem Cloud is the agent-native platform for building AI agents and distributed applications that never lose state, never duplicate work, and never require you to build…
When your agent uses it
- Porting an existing decorator-based TS agent
- You see @agent()/extends BaseAgent/@endpoint/@description code that no longer compiles
- Asked to modernize a TS component to the current SDK
Example prompts
- “/migrate-ts-decorator-sdk”
Workflow steps
10 steps, taken from the first numbered list in SKILL.md.
- Delete decorator imports and any @golemcloud/golem-ts-typegen usage.
- Remove experimentalDecorators / emitDecoratorMetadata from tsconfig.json.
- Convert each @agent class to defineAgent({...}) + .implement({...}); constructor params → id; class fields → init() state.
- Convert method signatures to method({ input, returns }) with Standard Schema; @description/@prompt/@readonly/@endpoint → method options +…
- Convert Result returns to s.result(ok, err).
- Convert Config/Secret constructor params to a config record (s.secret(...) for secrets).
- Convert save/loadSnapshot overrides to snapshotting (or .implement({ snapshot })).
- Ensure every agent module is imported from src/main.ts.
- Remove the old decorator/base/typegen dependencies and all compatibility wrappers.
- Build the local SDK bundle and agent template, then point the application build at those local
What it can do on your machine
Read from SKILL.md and the folder at commit c6a3029. 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
Shell commands in SKILL.md call:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
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
Migrate TS Decorator SDK loads about 3k tokens when it runs. Until then it costs about 93 tokens; SKILL.md has 936 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 936 words (~3,029 tokens).
“The decorator/base surface of @golemcloud/golem-ts-sdk (@agent() classes extending BaseAgent, @golemcloud/golem-ts-typegen) has been removed. The schema-driven API — defineAgent({...}).implement({...}) — is now the TypeScript authoring surface. This skill maps every old construct to its current replacement.”
