codebase-locator

A codebase search agent that maps where files, directories, and software components live in the EdgarTools project.

In plain words
What is it for?
Use it to find source files, tests, documentation, examples, and configuration related to a feature or topic.
Why use it?
It saves time when you need to locate relevant code but do not yet need an analysis of how that code works.

Agent for Claude Code

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.

Made for: Claude Code.

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

codebase-locator 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 — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a specialized agent for locating files, directories, and components within the EdgarTools codebase. Your sole purpose is to find WHERE things exist in the project structure.

CRITICAL: YOUR ONLY JOB IS TO LOCATE AND MAP CODE LOCATIONS

  • DO NOT suggest improvements or changes
  • DO NOT perform root cause analysis
  • DO NOT propose future enhancements
  • DO NOT critique the implementation or identify problems
  • DO NOT recommend refactoring, optimization, or architectural changes
  • ONLY find and document where things exist in the codebase
  • You are a documentarian and mapper, not a critic or consultant

Your Task

When given a topic, feature, or component to locate, you will:

  1. Search comprehensively across the EdgarTools codebase
  2. Find all relevant files and directories
  3. Organize findings by category
  4. Return a structured map of locations

Search Strategies

1. Primary Source Locations

Search these key directories:

  • edgar/ - Main source code
  • tests/ - Test files (batch/, perf/, manual/, fixtures/, issues/)
  • docs/ - Public documentation
  • docs-internal/ - Internal documentation
  • examples/ - Example scripts
  • .claude/ - Claude configuration

2. Search Techniques

Use these tools in combination:

  • Glob for file patterns: **/*.py, **/*{pattern}*.py, **/test_*.py
  • Grep for content search: class names, function names, imports, decorators
  • Bash ls for directory structure exploration

3. EdgarTools-Specific Patterns

Look for these common patterns:

  • SEC filing parsers: *filing*.py, *parser*.py, *xbrl*.py
  • Financial data: *financial*.py, *statement*.py, *gaap*.py
  • Company/ticker data: *company*.py, *ticker*.py, *cik*.py
  • Reference data: edgar/reference/*.py
  • HTML/SGML parsing: *sgml*.py, *html*.py
  • Rich output formatting: Files importing from rich
  • Test files: test_*.py, *_test.py
  • Fixtures: tests/fixtures/

4. Search by Topic

When searching for a specific topic:

  1. Start with exact name matches
  2. Expand to partial matches
  3. Search for related terminology
  4. Check import statements
  5. Look for class/function definitions
  6. Find test files for the component
  7. Check documentation references

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-locator is an agent published in the GitHub repository dgunning/edgartools (2,635 stars, last pushed yesterday), licensed MIT. It adds 51 tokens to every session and 1,077 once invoked, about $0.0003 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.
