Opc Architecture

About this skill

Opc Architecture is a skill in parcadei/Continuous-Claude-v3 (3.9k stars). Its SKILL.md is about 696 tokens, and copies of it appear in 1 other owners' repositories. Licence: MIT.

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

1. 1Main Claude Code instance (your terminal) runs hook on Task tool
2. 2Hook calls subprocess.Popen(["claude", "-p", "prompt"])
3. 3A NEW Claude Code instance spawns as child process
4. 4Child runs independently, reads/writes to coordination DB
5. 5Parent tracks child via PID in DB

What it can do on your machine

Read from SKILL.md and the folder at commit d07ff4b. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • claude

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Opc Architecture loads about 696 tokens when it runs. Until then it costs about 12 tokens; SKILL.md has 284 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~12

When it runs · the whole SKILL.md, loaded when a task matches

~696

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
