cli-claude-code

cli-claude-code is a skill for Claude Code, OpenCode from MichelKerkmeester/skilled-agent-harness_spec-driven-loops. It costs 28 tokens per session (7,043 once invoked), scanned A, original, MIT.

A skill that sends coding, editing, review, and reasoning tasks to Anthropic’s Claude Code command-line tool, with support for passing results between different AI systems.

In plain words
What is it for?
It is for deep reasoning, precise code changes, reviews, and structured handoffs between AI tools.
Why use it?
It lets one AI delegate suitable work to Claude Code instead of handling every task alone.

Written for Claude Code and OpenCode: allowed-tools in frontmatter, but also installed under .opencode/. Also seen: reads .claude/ paths; mentions Claude Code; mentions AGENTS.md.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is printf '%s' "$JSON_PAYLOAD" | node .opencode/skills/system-spec-kit/runtime/cli/dist/continuity/generate-context.js --stdin [spec-folder].

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 →

    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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-claude-code scanned grade A with 1 finding 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 4d 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.

Claude Code CLI Orchestrator - Cross-AI Task Delegation

CRITICAL — SELF-INVOCATION PROHIBITED

This skill dispatches to the Anthropic CLI binary (claude). If the agent currently reading this skill is itself running inside Claude Code (detection signals listed in §2), the skill MUST refuse to load and return the documented error message instead of generating any claude invocation.

A running CLI skill never dispatches itself. The cli-X skills are for cross-AI delegation only — never self-invocation.

Orchestrate Anthropic's Claude Code CLI from external AI assistants (OpenCode, Copilot, etc.) for tasks that benefit from deep extended thinking, surgical code editing, structured output with JSON schema validation, agent delegation, or persistent memory context.

Core Principle: The calling AI stays the conductor. Delegate to Claude Code for what it does best — deep reasoning, precise code editing, and structured analysis. Validate and integrate the output.

1. WHEN TO USE

Activation Triggers

  • Deep Reasoning — extended-thinking architectural decisions, multi-dimensional trade-off analysis, step-by-step algorithm design, root-cause analysis of subtle bugs.
  • Code Editing — surgical diff-based edits, pattern-preserving refactors, and multi-file coordinated changes.
  • Structured Output — --json-schema-validated output, machine-readable analysis, guaranteed-structure data extraction, pipeline integration.
  • Code Review — second-AI security audits, extended-thinking architecture review, cross-AI validation, pre-merge quality gates.
  • Agent-Delegated Tasks — specialized .claude/agents/*.md matches, --permission-mode plan read-only exploration, @ai-council planning, session continuity (--continue, --resume).
  • Background Processing — long-running offloaded analysis, parallel generation/docs, batch processing with --max-budget-usd cost control.

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.

cli-claude-code is a skill published in the GitHub repository MichelKerkmeester/skilled-agent-harness_spec-driven-loops (35 stars, last pushed yesterday), licensed MIT. It adds 28 tokens to every session and 7,043 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
