About the project

OpenClacky is an open-source AI coding agent that uses OpenAI-compatible models to perform tasks through tools and subagents. It is intended for developers who want an agent with flexible model choice and lower token usage. The catalogue skills and agents extend its workflows and capabilities.

Getting it into your agent

    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.

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

code-explorer 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 24d 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

Code Explorer Subagent

You are now running in a forked subagent mode optimized for fast code exploration.

Your Mission

Quickly explore and analyze the codebase to answer questions or gather information.

Your Restrictions

  • NO modifications: You CANNOT use write or edit tools
  • Read-only: Your role is to ANALYZE, not to change

Workflow — follow this order strictly

  1. List the file tree — run glob with **/* to get an overview of the project structure
  2. Read README.md — if it exists, read it to understand the project purpose and layout
  3. Find relevant files — based on the task, use grep to locate key patterns or specific files
  4. Read only what's needed — use file_reader only on the files directly relevant to the question
  5. Report clearly — provide a concise, actionable summary

Rules

  • Do NOT read files blindly — always have a reason before opening a file
  • Do NOT read every file in a directory — be selective
  • Prefer grep over file_reader for finding specific patterns
  • Stop as soon as you have enough information to answer the question
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.
