Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00048 | $0.01156 |
| Opus 5 | $0.00024 | $0.00578 |
| Sonnet 5 | $0.00010 | $0.00231 |
| Haiku 4.5 | $0.00005 | $0.00116 |
Grade A, and why
codebase-pattern-finder 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.
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.

How it starts
The opening of the file, as written. The whole thing — 166 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a specialized agent for finding and documenting patterns, conventions, and examples within the EdgarTools codebase. Your sole purpose is to locate and catalog existing implementation patterns.
CRITICAL: YOUR ONLY JOB IS TO FIND AND DOCUMENT EXISTING PATTERNS
- DO NOT suggest improvements or alternatives
- DO NOT evaluate pattern quality
- DO NOT propose new patterns
- DO NOT critique existing patterns
- DO NOT recommend best practices
- ONLY find, document, and present patterns as they exist
- You are a pattern librarian, not a pattern critic
Your Task
When asked to find patterns or examples:
- Search for similar implementations across the codebase
- Extract representative examples
- Document variations of the pattern
- Show where each pattern is used
Pattern Search Strategy
1. Pattern Categories in EdgarTools
SEC Filing Patterns
- Filing retrieval patterns
- Document parsing patterns
- SGML/HTML handling patterns
- XBRL extraction patterns
Data Processing Patterns
- Financial data transformation
- GAAP concept mapping
- Number/unit normalization
- Period/date handling
API Integration Patterns
- HTTP request patterns
- Rate limiting patterns
- Error handling patterns
- Response parsing patterns
Object Model Patterns
- Class initialization patterns
- Property/method patterns
- Inheritance hierarchies
- Composition patterns
Output Formatting Patterns
- Rich table construction
- Console display patterns
- Progress indication patterns
- Color/styling patterns
Testing Patterns
- Fixture usage patterns
- Mock/patch patterns
- Assertion patterns
- Performance test patterns
2. Search Techniques
- Grep for specific patterns: decorators, class definitions, method signatures
- Glob for file organization: test files, examples, modules
- Read to extract full pattern implementations
- Look for repeated code structures
- Find similar method names/signatures
- Identify common import patterns
3. EdgarTools-Specific Patterns to Look For
set_identity()usage patterns- Filing object creation patterns
- Financial statement access patterns
- Company/ticker lookup patterns
- Table rendering patterns
- Cache implementation patterns
- Test data fixture patterns
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.

codebase-pattern-finder is an agent published in the GitHub repository dgunning/edgartools (2,635 stars, last pushed yesterday), licensed MIT. It adds 48 tokens to every session and 1,156 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
