fuzzy-search

fuzzy-search is a skill for Claude Code, Codex from cxcscmu/SkillLearnBench. It costs 22 tokens per session (194 once invoked), scanned A, original, MIT.

A guide to fuzzy text matching, which finds close rather than exact name matches. It uses thefuzz to match fund names and stock CUSIPs, identifiers used to identify securities, against issuer names.

In plain words
What is it for?
Use it to find likely fund or stock matches in filing data and return the closest results with scores.
Why use it?
It helps locate records when names differ in spelling, word order, or formatting.

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

fuzzy-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

Fuzzy Search for 13-F Data

Setup

pip install thefuzz python-Levenshtein
from thefuzz import fuzz, process

# Search in COVERPAGE for fund name
results = process.extract(search_term, cover['FILINGMANAGER_NAME'].tolist(), scorer=fuzz.token_sort_ratio, limit=5)
# Returns list of (match, score, index)

Stock CUSIP Search by Issuer Name

# Get unique issuers with CUSIPs
issuers = info[['NAMEOFISSUER','CUSIP']].drop_duplicates()
results = process.extract(stock_name, issuers['NAMEOFISSUER'].tolist(), scorer=fuzz.token_sort_ratio, limit=5)
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.
