What it does
Go Process CLI is an agent skill from pproenca/dot-skills. Write Go CLIs that manage processes and workloads — daemons, supervisors, job runners, deploy tools, anything that spawns or controls other processes. Use when writing, reviewing, or refactoring Go that handles OS signals, runs children via os/exec, fans out concurrent work, threads context for cancellation, returns exit codes, or builds a flag/cobra command surface. Covers the footguns the standard library makes easy to hit — SIGTERM vs Ctrl-C, SIGKILL-by-default children, orphaned process groups, pipe…
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 31 other files, including reference files and assets (for example `AGENTS.md`, `assets/templates/_template.md` and `metadata.json`).
It sits in Development, covering Async programming and Refactoring. The repository describes itself as: A collection of AI agent skills following the Agent Skills open format. The licence is MIT.
When your agent uses it
- Refactoring Go that handles OS signals
- Runs children via os/exec
- Fans out concurrent work
- Threads context for cancellation
Example prompts
- “/go-process-cli”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Identify which category your task falls under (see table above).
- Read the relevant rule files in references/ — each is a focused, self-contained pattern naming the wrong default it corrects.
- Apply the pattern; follow the Reference link in each rule for the authoritative source.
What it can do on your machine
Read from SKILL.md and the folder at commit cf93c57. 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
Shell commands in SKILL.md call:
sh
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
Go Process CLI loads about 1.2k tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 191 tokens; SKILL.md has 483 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.

- description
- Write Go CLIs that manage processes and workloads — daemons, supervisors, job runners, deploy tools, anything that spawns or controls other processes. Use when writing, reviewing, or refactoring Go that handles OS signals, runs children via os/exec, fans out concurrent work, threads context for cancellation, returns exit codes, or builds a flag/cobra command surface. Covers the footguns the standard library makes easy to hit — SIGTERM vs Ctrl-C, SIGKILL-by-default children, orphaned process groups, pipe deadlocks, goroutine leaks, zombie reaping, and os.FindProcess lying about liveness. Triggers whenever the task touches process lifecycle, graceful shutdown, subprocess control, or concurrent workload supervision in Go — even if not named.
Go Process-Management CLIs
Make Go command-line tools that spawn, supervise, and shut down processes correctly — the part the stdlib makes easy to get subtly wrong.
When to Apply
Reach for this skill when building or reviewing a Go CLI whose job is to control other processes or concurrent workloads: a daemon, a process supervisor, a job/worker runner, a deploy or migration tool, a test harness that shells out, or any program that must stop cleanly when an orchestrator says so. It targets Go 1.22+ on Unix-like systems (Linux, macOS); a few rules note where Windows differs. It assumes you already know Go — it only corrects the specific defaults that go wrong in this domain.
Categories
| # | Category | Prefix | What it covers |
|---|---|---|---|
| 1 | Signals & Graceful Shutdown | sig | Binding a context to SIGINT/SIGTERM; second-signal force-quit |
| 2 | Child Processes | exec | os/exec lifetime, graceful kill, process groups, pipes, exit codes |
| 3 | Concurrency & Workloads | work | errgroup fan-out, bounded concurrency, goroutine-leak discipline, channel ownership |
| 4 | Context Propagation | ctx | Explicit context args, defer cancel(), cancellable waits |
| 5 | Errors & Exit Codes | err | run() error for deferred cleanup, aggregating failures |
| 6 | CLI Framework & Flags | cli | stdlib flag vs cobra, ExecuteContext, RunE, subcommand patterns |
| 7 | Process State & Supervision | state | Liveness probes, atomic PID files, zombie reaping, structured logs |
Quick Reference
The defaults this skill exists to correct:
signal.NotifyContext(ctx, SIGINT, SIGTERM)— not a channel that only watches Ctrl-C. Orchestrators send SIGTERM.exec.CommandContext+cmd.Cancel/cmd.WaitDelay— plainCommandContextSIGKILLs children with no cleanup.Setpgid+kill(-pgid)— signalling the direct child orphans grandchildren (sh -c,make,npm).cmd.Output()for capture — reading a pipe afterWait()deadlocks.errgroup.WithContext+SetLimit(n)— a goroutine per task means a process per task: PID/FD exhaustion.ctxas an argument — never a struct field;defer cancel()on every derived context.select { case <-ticker.C: case <-ctx.Done(): }—time.Sleepmakes shutdown wait out the interval.main → run() error → os.Exit(1)—log.Fatal/os.Exitdeep in code skip everydefer.proc.Signal(syscall.Signal(0))—os.FindProcessalways succeeds on Unix; it never proves liveness.os.OpenFile(O_CREATE|O_EXCL)for PID files — check-then-create is a race;cmd.Wait()every child or it zombifies.

How to Use
- Identify which category your task falls under (see table above).
- Read the relevant rule files in
references/— each is a focused, self-contained pattern naming the wrong default it corrects. - Apply the pattern; follow the
Referencelink in each rule for the authoritative source.
Rules cross-link (e.g. graceful shutdown ties signals → context → child-process kill → cleanup), so follow the links when a task spans categories.
When extending this skill, copy assets/templates/_template.md: WHY first, one canonical example with realistic names, a foil only if the wrong way is a genuine trap.
Source Authority
Every rule cites primary sources — the Go standard library reference on pkg.go.dev, the official Go blog (go.dev/blog), and the cobra documentation — chosen because they are maintainer-authored and version-current. No content farms, listicles, or undated tutorials.
