evo-parallel-batch-search

evo-parallel-batch-search is a skill for Claude Code, Codex from OpenLAIR/OpenSkill. It costs 40 tokens per session (281 once invoked), scanned A, original, Apache-2.0.

A parallel search tool for running many queries against an existing TF-IDF index. TF-IDF is a text-search scoring method that ranks documents by how relevant their words are.

In plain words
What is it for?
Use it to search a prepared text index for many queries, return the top matching documents, and measure elapsed processing time.
Why use it?
It avoids repeatedly copying the same read-only search index to every worker process. Independent queries can be handled at the same time instead of one after another.

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

evo-parallel-batch-search 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 yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/utils.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Overview

Parallelizes batch query search using ProcessPoolExecutor with the worker initializer pattern. The index is passed once per worker at pool creation time (via initargs), avoiding repeated pickling.

Worker Initializer Pattern

  • init_search_worker(index, documents, top_k) sets module-level globals
  • worker_search_query(query) reads those globals to perform search
  • Each query is independent - perfect for data parallelism

Usage

import sys
sys.path.insert(0, '/app/environment/skills/evo-parallel-batch-search/scripts')
from utils import (
    init_search_worker,
    worker_search_query,
    batch_search_parallel
)

# Batch search
results, elapsed = batch_search_parallel(
    queries, index, top_k=10, num_workers=4, documents=docs
)

Functions

  • init_search_worker(index_data, documents_data, top_k) - Worker initializer
  • worker_search_query(query) - Per-query search in worker process
  • batch_search_parallel(queries, index, top_k, num_workers, documents) - Full pipeline
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
