ai-friendly-cli

ai-friendly-cli is a skill for Claude Code, Codex from dashed/claude-marketplace. It costs 60 tokens per session (2,290 once invoked), scanned C, original, no licence file.

A set of instructions for building command-line tools that AI agents can use and understand reliably.

In plain words
What is it for?
Use it when adding JSON output, dry-run options, input checks, schema information, or both CLI and MCP interfaces.
Why use it?
It helps address problems such as unclear output, unsafe inputs, and commands that are difficult for agents to operate.

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 C, and why

ai-friendly-cli scanned grade C with 2 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 5d 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.

Instruction-override phrasingmediumPrompt injection

Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.

# Strips sequences like "IGNORE ALL PREVIOUS INSTRUCTIONS" from response fields

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Reaches for credential filesmediumPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

- **Path traversals**: `../../etc/passwd`, `../.ssh/id_rsa`

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

What ships with it

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.

ai-friendly-cli is a skill published in the GitHub repository dashed/claude-marketplace (22 stars, last pushed yesterday), with no licence file. It adds 60 tokens to every session and 2,290 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 2 findings (instruction-override phrasing, reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
