What it does
Fp Taskeither Ref is an agent skill from sickn33/agentic-awesome-skills. Quick reference for TaskEither. Use when user needs async error handling, API calls, or Promise-based operations that can fail.
Its SKILL.md is about 740 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 Development. 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 needs async error handling
- Promise-based operations that can fail
Example prompts
- “/fp-taskeither-ref”
What it can do on your machine
Read from SKILL.md and the folder at commit b84d35a. 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 Taskeither Ref loads about 744 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 112 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.

TaskEither Quick Reference
TaskEither = async operation that can fail. Like Promise<Either<E, A>>.
When to Use
- You need a quick fp-ts reference for async operations that can fail.
- The task involves API calls, Promise wrapping, or composing asynchronous error-handling pipelines.
- You want a concise cheat sheet for
TaskEitheroperators and patterns.
Create
import * as TE from 'fp-ts/TaskEither'
TE.right(value) // Async success
TE.left(error) // Async failure
TE.tryCatch(asyncFn, toError) // Promise → TaskEither
TE.fromEither(either) // Either → TaskEitherTransform
TE.map(fn) // Transform success value
TE.mapLeft(fn) // Transform error
TE.flatMap(fn) // Chain (fn returns TaskEither)
TE.orElse(fn) // Recover from errorExecute
// TaskEither is lazy - must call () to run
const result = await myTaskEither() // Either<E, A>
// Or pattern match
await pipe(
myTaskEither,
TE.match(
(err) => console.error(err),
(val) => console.log(val)
)
)()Common Patterns
import { pipe } from 'fp-ts/function'
import * as TE from 'fp-ts/TaskEither'
// Wrap fetch
const fetchUser = (id: string) => TE.tryCatch(
() => fetch(`/api/users/${id}`).then(r => r.json()),
(e) => ({ type: 'NETWORK_ERROR', message: String(e) })
)
// Chain async calls
pipe(
fetchUser('123'),
TE.flatMap(user => fetchPosts(user.id)),
TE.map(posts => posts.length)
)
// Parallel calls
import { sequenceT } from 'fp-ts/Apply'
sequenceT(TE.ApplyPar)(
fetchUser('1'),
fetchPosts('1'),
fetchComments('1')
)
// With recovery
pipe(
fetchUser('123'),
TE.orElse(() => TE.right(defaultUser)),
TE.getOrElse(() => defaultUser)
)vs async/await
// ❌ async/await - errors hidden
async function getUser(id: string) {
try {
const res = await fetch(`/api/users/${id}`)
return await res.json()
} catch (e) {
return null // Error info lost
}
}
// ✅ TaskEither - errors typed and composable
const getUser = (id: string) => pipe(
TE.tryCatch(() => fetch(`/api/users/${id}`), toNetworkError),
TE.flatMap(res => TE.tryCatch(() => res.json(), toParseError))
)Use TaskEither when you need typed errors for async operations.
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.
