At a glance

Exposes and consumes Durable Streams with Effect. An agent skill from golemcloud/golem.

  • Stream-bearing HTTP methods
  • SKILL.md covers Expose a Stream-Bearing Method, Protocol Rules and Read and Write Compatible URLs
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Durable Streams session and slot URLs

What it does

Golem Durable Streams Effect is an agent skill from golemcloud/golem. Exposes and consumes Durable Streams with Effect. Use for stream-bearing HTTP methods, Durable Streams session and slot URLs, external readers or writers, replay-safe appends, or protocol-compatible stream services.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

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

  • Stream-bearing HTTP methods
  • Durable Streams session and slot URLs
  • External readers
  • Replay-safe appends

Example prompts

  • “Use the golem-durable-streams-effect skill to expose and consumes Durable Streams with Effect. An agent skill from golemcloud/golem”
  • “/golem-durable-streams-effect”

What it can do on your machine

Read from SKILL.md and the folder at commit 2dea6b9. 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 and bash).

    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 Durable Streams Effect loads about 1.4k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 481 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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 481 words (~1,397 tokens).

“Durable Streams is the resumable HTTP protocol for an invocation's typed stream slots. It differs from generic agent-to-agent streaming: WitTypes.AgentStream(...) and native Effect Stream values define RPC data; Durable Streams adds stable session/slot URLs for external append, read, resume, cancellation…”
