What it does
Go Concurrency Pipelines is an agent skill from hashgraph-online/awesome-codex-plugins. Design, implement, test, and review bounded in-process Go concurrency using goroutines, channels, iterators, mutexes, shared collections, WaitGroup, errgroup, backpressure, ordering, cancellation, and deterministic lifecycle checks. Use when building worker pools, streaming pipelines, concurrent batches, background stages, or diagnosing races, goroutine leaks, blocked operations, synchronization ownership, and shutdown failures.
Its SKILL.md is about 850 tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including reference files (for example `agents/openai.yaml`, `guidelines.md` and `references/concurrency-pipelines/examples.md`). Compatibility notes: Codex, Claude Code, and other Agent Skills-compatible clients.
It sits in Development, covering Async programming. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is MIT.
When your agent uses it
- Building worker pools
- Streaming pipelines
- Concurrent batches
- Background stages
Example prompts
- “/go-concurrency-pipelines”
Requirements
- Compatibility (from SKILL.md): Codex, Claude Code, and other Agent Skills-compatible clients.
Workflow steps
9 steps, taken from the first numbered list in SKILL.md.
- Define input, output, ordering, partial-result, and failure contracts.
- Prefer a synchronous or iterator API unless callers need channel mechanics.
- Assign ownership of goroutines, channel closure, timers, and cancellation.
- Bound concurrency, queues, retries, and memory together.
- Make every blocking send, receive, and wait cancellation-aware.
- Join all owned goroutines on success, failure, cancellation, and early exit.
- Test lifecycle behavior with barriers and deadlines rather than sleeps.
- Review shared maps, slices, locks, wait groups, and copied synchronization values.
- Run race checks and inspect leak-prone paths.
What it can do on your machine
Read from SKILL.md and the folder at commit 3e1456a. 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.
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):
go.devpkg.go.devmanning.com
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.
Compatibility
Codex, Claude Code, and other Agent Skills-compatible clients.
From compatibility in the SKILL.md frontmatter.
Context cost
Go Concurrency Pipelines loads about 849 tokens when it runs, and up to ~2.9k if it reads all its reference files. Until then it costs about 114 tokens; SKILL.md has 307 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.

Go Concurrency Pipelines
Every goroutine needs an owner, a stop condition, and a completion path. Bound admission before optimizing throughput.
Core Workflow
- Define input, output, ordering, partial-result, and failure contracts.
- Prefer a synchronous or iterator API unless callers need channel mechanics.
- Assign ownership of goroutines, channel closure, timers, and cancellation.
- Bound concurrency, queues, retries, and memory together.
- Make every blocking send, receive, and wait cancellation-aware.
- Join all owned goroutines on success, failure, cancellation, and early exit.
- Test lifecycle behavior with barriers and deadlines rather than sleeps.
- Review shared maps, slices, locks, wait groups, and copied synchronization values.
- Run race checks and inspect leak-prone paths.

Guardrails
- Only a sender that owns completion closes a channel.
- Do not use a buffer as a substitute for cancellation and joining.
- Do not expose internal channels when an iterator or synchronous result suffices.
- Do not assume
selectguarantees fairness. - Do not multiply a concurrency limit through hidden retries or nested fan-out.
- Do not prove timing behavior with arbitrary sleeps.
- Do not copy values containing mutexes, wait groups, conditions, or other sync state.
- Do not detach work from a request without a new bound, owner, error sink, and join policy.
