- User asks which type to use

What it does
Fp Types Ref is an agent skill from sickn33/agentic-awesome-skills. Quick reference for fp-ts types. Use when user asks which type to use, needs Option/Either/Task decision help, or wants fp-ts imports.
Its SKILL.md is about 580 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: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
When your agent uses it
- User asks which type to use
- Needs Option/Either/Task decision help
- Wants fp-ts imports
Example prompts
- “/fp-types-ref”
What it can do on your machine
Read from SKILL.md and the folder at commit ec02547. 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
Fp Types Ref loads about 583 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 135 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.

fp-ts Quick Reference
When to Use
- You need help choosing between
Option,Either,Task,TaskEither, or related fp-ts types. - The task is about imports, decision guidance, or selecting the right abstraction for a TypeScript flow.
- You want a compact reference for common fp-ts type choices and patterns.
Which Type Should I Use?
Is the operation async?
├─ NO: Does it involve errors?
│ ├─ YES → Either<Error, Value>
│ └─ NO: Might value be missing?
│ ├─ YES → Option<Value>
│ └─ NO → Just use the value
└─ YES: Does it involve errors?
├─ YES → TaskEither<Error, Value>
└─ NO: Might value be missing?
├─ YES → TaskOption<Value>
└─ NO → Task<Value>Common Imports
// Core
import { pipe, flow } from 'fp-ts/function'
// Types
import * as O from 'fp-ts/Option' // Maybe exists
import * as E from 'fp-ts/Either' // Success or failure
import * as TE from 'fp-ts/TaskEither' // Async + failure
import * as T from 'fp-ts/Task' // Async (no failure)
import * as A from 'fp-ts/Array' // Array utilitiesOne-Line Patterns
| Need | Code |
|---|---|
| Wrap nullable | O.fromNullable(value) |
| Default value | O.getOrElse(() => default) |
| Transform if exists | O.map(fn) |
| Chain optionals | O.flatMap(fn) |
| Wrap try/catch | E.tryCatch(() => risky(), toError) |
| Wrap async | TE.tryCatch(() => fetch(url), toError) |
| Run pipe | pipe(value, fn1, fn2, fn3) |
Pattern Match
// Option
pipe(maybe, O.match(
() => 'nothing',
(val) => `got ${val}`
))
// Either
pipe(result, E.match(
(err) => `error: ${err}`,
(val) => `success: ${val}`
))Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
