At a glance
Portable Effect patterns for robust promise execution. An agent skill from millionco/expect.
- Wrapping async operations with timeouts
- SKILL.md covers Quick Reference, Core Pattern: Portable Effect…, Tagged Errors and Timeouts, plus 7 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does
Effect Portable Patterns is an agent skill from millionco/expect. Portable Effect patterns for robust promise execution. Use when wrapping async operations with timeouts, retries, tagged errors, caching, concurrency, pattern matching, or tracing - all designed to resolve to a plain Promise via Effect.runPromise.
Its SKILL.md is about 3.7k 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 Backend & APIs, covering Caching. The repository describes itself as: Expect tests your agent's code in a real browser.
When your agent uses it
- Wrapping async operations with timeouts
- Pattern matching
- Tracing - all designed to resolve to a plain Promise via Effect.runPromise
Example prompts
- “/effect-portable-patterns”
What it can do on your machine
Read from SKILL.md and the folder at commit 39e9750. 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
Links to these hosts (documentation or services it may open):
effect.website
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
Effect Portable Patterns loads about 3.7k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 413 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 413 words (~3,735 tokens).
“Use Effect as a lightweight utility for running promises robustly. Every effect is self-contained (no services, no layers, no dependency injection) and resolves to a plain Promise at the boundary via Effect.runPromise.”
