13f-search

13f-search is a skill for Claude Code, Codex from cxcscmu/SkillLearnBench. It costs 18 tokens per session (164 once invoked), scanned A, original, MIT.

A fuzzy-name search tool for finding a fund's regulatory accession number or a stock's CUSIP. An accession number identifies a regulatory filing, while a CUSIP identifies a security.

In plain words
What is it for?
Use it to search for fund accession numbers by quarter and stock CUSIPs by company name.
Why use it?
It helps when you know an entity's name but need the exact identifier used in financial records. Fuzzy matching can handle names that are not entered exactly.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 /root/.agents/skills/fuzzy-name-search/scripts/search_fund.py --keywords "Fund Name" --quarter 2025-q3.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

13f-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 3d 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

Overview

Use the provided scripts to find the unique identifier (ACCESSION_NUMBER) for a fund or the CUSIP for a stock.

Usage

Finding a Fund's Accession Number

To find the accession number for a fund in a specific quarter:

python3 /root/.agents/skills/fuzzy-name-search/scripts/search_fund.py --keywords "Fund Name" --quarter 2025-q3

Finding a Stock's CUSIP

To find the CUSIP for a company:

python3 /root/.agents/skills/fuzzy-name-search/scripts/search_stock_cusip.py --keywords "Company Name"
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.
