cli-agent-lint: Instructions file for Codex

AGENTS.md

cli-agent-lint AGENTS.md is an instructions file for Codex, OpenCode from Camil-H/cli-agent-lint. It costs 466 tokens per session, scanned A, original, MIT.

Instructions for cli-agent-lint, a command-line checker that reviews whether another command-line tool is suitable for use by AI agents.

In plain words
What is it for?
It helps audit a command-line tool, produce machine-readable JSON results, run passive checks, filter by category or severity, skip checks, and set probe timeouts.
Why use it?
It helps find interfaces that are unsafe, hard to understand, inefficient with text, unpredictable, or difficult to automate.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is Camil-H/cli-agent-lint's own configuration. It tells Codex and OpenCode how to work on cli-agent-lint itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything cli-agent-lint configures →

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

cli-agent-lint AGENTS.md 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 2mo 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.

What it actually says

cli-agent-lint — Agent Skill File

What this tool does

cli-agent-lint audits CLI tools for AI agent-readiness. It checks across five categories: flow safety, token efficiency, self-describing, automation safety, and predictability.

Usage

# Audit a CLI tool
cli-agent-lint check <target-cli>

# JSON output (machine-readable)
cli-agent-lint check <target-cli> --output json

# Passive checks only (no subprocess execution)
cli-agent-lint check <target-cli> --no-probe

# List all checks
cli-agent-lint checks

# Describe a specific check
cli-agent-lint checks <check-id>

Exit codes

  • 0: all checks passed
  • 1: one or more fail-severity checks did not pass
  • 2: cli-agent-lint itself errored

Key flags

  • --output json — structured JSON report to stdout
  • --no-color — disable ANSI colors
  • --quiet — suppress diagnostics, only essential output
  • --no-probe — passive checks only, no subprocess execution
  • --severity <level> — minimum severity: info, warn, fail
  • --category <name> — filter by check category
  • --skip <id> — skip specific checks (repeatable)
  • --timeout <duration> — probe timeout (default 5s)

Security

Active checks (default) execute the target CLI as a subprocess. Use --no-probe when auditing untrusted CLIs to restrict to passive help-text analysis only. Sensitive environment variables (tokens, secrets, API keys) are stripped before execution, but the target can still make network requests and read local files.

Interpreting results

The JSON report contains a score object with percentage and grade (A-F). Each check in the checks array has id, status (pass/fail/warn/skip), severity, and recommendation.

Conventions

  • Errors and diagnostics go to stderr
  • Data output goes to stdout
  • No interactive prompts — all input via flags/args
  • Respects NO_COLOR env var
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.
