What it does
Go CLI Process Control is an agent skill from hashgraph-online/awesome-codex-plugins. Execute and supervise external programs safely from Go CLIs with explicit arguments, typed failure classification, working directories, environments, bounded streams, deadlock-safe pipes, contexts, timeouts, signals, platform adapters, descendant cleanup, runner seams, and lifecycle tests. Use when wrapping a command, diagnosing start or exit failures, hangs, deadlocks, or orphan processes, or implementing cancellable cross-platform CLI workflows.
Its SKILL.md is about 860 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/process-control/checklist.md`). Compatibility notes: Codex, Claude Code, and other Agent Skills-compatible clients.
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
- Wrapping a command
- Diagnosing start
- Orphan processes
- Implementing cancellable cross-platform CLI workflows
Example prompts
- “/go-cli-process-control”
Requirements
- Compatibility (from SKILL.md): Codex, Claude Code, and other Agent Skills-compatible clients.
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Define the child executable, argv, environment, directory, streams, and success contract.
- Use an explicit shell only when shell semantics are actually required.
- Inject a runner boundary and propagate the caller's context.
- Observe startup and completion; preserve status and useful redacted stderr.
- Bound captured output, cancellation, and shutdown time.
- Account for descendants and wait for every pipeline stage.
- Test missing tools, bad exits, malformed output, cancellation, signals, and cleanup.
What it can do on your machine
Read from SKILL.md and the folder at commit 78497e5. 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):
pkg.go.devpragprog.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 CLI Process Control loads about 856 tokens when it runs, and up to ~8k if it reads all its reference files. Until then it costs about 119 tokens; SKILL.md has 301 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 CLI Process Control
Treat child-process lifecycle as correctness. Observe the terminal result, propagate cancellation, and clean up every process, pipe, and temporary resource.
Core Workflow
- Define the child executable, argv, environment, directory, streams, and success contract.
- Use an explicit shell only when shell semantics are actually required.
- Inject a runner boundary and propagate the caller's context.
- Observe startup and completion; preserve status and useful redacted stderr.
- Bound captured output, cancellation, and shutdown time.
- Account for descendants and wait for every pipeline stage.
- Test missing tools, bad exits, malformed output, cancellation, signals, and cleanup.

| Apply modern execution and cancellation rules | references/process-control/rules.md |

| Start from focused code examples | references/process-control/examples.md |
| Review a subprocess boundary | references/process-control/checklist.md |
| Understand lifecycle and shell semantics | references/process-control/knowledge.md |
Guardrails
- Pass executable arguments separately; never assume
exec.Commandinvokes a shell. - Do not treat
Startas success; inspect the terminal result. - Do not assume context cancellation terminates an entire process tree.
- Close owned pipes and wait for every started process.
- Distinguish lookup, start, exit, timeout, cancellation, and cleanup failures.
- Treat
Cmd.String()as diagnostic text, never shell-safe replay or secret-safe output. - Avoid mutable package-level command hooks in concurrent tests.

Failure taxonomy, pipe ordering, and platform-adapter guidance also incorporates transformed material from Marian Montagnino, Building Modern CLI Applications in Go (Packt, 2023), especially Chapter 6.
