ai-native-cli-v2

ai-native-cli-v2 is a skill for Claude Code, Codex from diegosouzapw/awesome-omni-skills. It costs 84 tokens per session (5,277 once invoked), scanned A, original, MIT.

A specification for designing command-line tools that AI agents can use safely and reliably. It covers input and output formats, errors, safety rules, exit codes, and tool descriptions.

In plain words
What is it for?
Use it when building or changing a CLI that needs structured responses, predictable errors, and clear usage contracts.
Why use it?
Command-line tools can be hard for agents to understand and may fail ambiguously or handle unsafe input. This defines clearer behavior and safety expectations.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ai-native-cli-v2 scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Agent-Friendly CLI Spec v0.1

Overview

This public intake copy packages plugins/antigravity-awesome-skills/skills/ai-native-cli from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the external_source block in metadata.json plus ORIGIN.md as the provenance anchor for review.

Agent-Friendly CLI Spec v0.1 When building or modifying CLI tools, follow these rules to make them safe and reliable for AI agents to use.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Core Philosophy, Layer Model, How It Works, Certification Requirements, Quick Implementation Checklist, Common Pitfalls.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

  • Use when building a new CLI tool that AI agents will invoke
  • Use when retrofitting an existing CLI to be agent-friendly
  • Use when designing command-line interfaces for automation pipelines
  • Use when auditing a CLI tool's compliance with agent-safety standards
  • Use when the request clearly matches the imported source intent: Design spec with 98 rules for building CLI tools that AI agents can safely use. Covers structured JSON output, error handling, input contracts, safety guardrails, exit codes, and agent self-description.
  • Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.

Operating Table

Situation Start here Why it matters
First-time use metadata.json Confirms repository, branch, commit, and imported path through the external_source block before touching the copied workflow
Provenance review ORIGIN.md Gives reviewers a plain-language audit trail for the imported source
Workflow execution SKILL.md Starts with the smallest copied file that materially changes execution
Supporting context SKILL.md Adds the next most relevant copied source file without loading the entire package

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
