What it does
Golem Agent Reflection TS is an agent skill from golemcloud/golem. Composing caller-defined static, discovered, and fully dynamic Golem clients in TypeScript. Use when schemas are caller-owned or discovered at runtime, or a ParsedAgentId must be rebound.
Its SKILL.md is about 3.6k 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
- Schemas are caller-owned
- Discovered at runtime
- A ParsedAgentId must be rebound
Example prompts
- “/golem-agent-reflection-ts”
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
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
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
Golem Agent Reflection TS loads about 3.6k tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 1,131 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 1,131 words (~3,646 tokens).
“Normal RPC is the non-reflective baseline: when producer and caller share a source definition, use the SDK's ordinary Target.client surface. Reflection adds caller-defined static clients, discovered clients, and fully dynamic clients. These surfaces compose through immutable schema snapshots and durable…”
