async-repl-protocol

async-repl-protocol is a skill for Claude Code, Codex from parcadei/Continuous-Claude-v3. It costs 10 tokens per session (148 once invoked), scanned A, original, MIT.

Rules for using Agentica's asynchronous REPL, an interactive environment where operations may finish later instead of immediately.

In plain words
What is it for?
Use it when testing with the async REPL to await file views or memory requests and keep computation and returned results in one code block.
Why use it?
It prevents errors caused by failing to wait for results and ensures the harness executes the complete response correctly.

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

async-repl-protocol 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 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.

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

Async REPL Protocol

When working with Agentica's async REPL harness for testing.

Rules

1. Use await for Future-returning tools

content = await view_file(path)  # NOT view_file(path)
answer = await ask_memory("...")

2. Single code block per response

Compute AND return in ONE block. Multiple blocks means only first executes.

# GOOD: Single block
content = await view_file(path)
return any(c.isdigit() for c in content)

# BAD: Split blocks (second block never runs)
content = await view_file(path)
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.
