agent-brain-types

A command that lists file-type presets for an indexing tool. The presets group common filename patterns, such as Python, JavaScript, documentation, or PDF files.

In plain words
What is it for?
Viewing available presets, choosing which file types to index, and scripting or documenting indexing commands.
Why use it?
It avoids writing individual file patterns when you want to index only certain kinds of files. The list also shows how to use and combine the presets.

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.

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

agent-brain-types 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 2d 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

File Type Presets

Purpose

Show all available file type presets that can be used with the --include-type flag during indexing. Presets are named groups of glob patterns that make it easy to index specific categories of files without writing individual patterns.

Usage

/agent-brain:agent-brain-types

Examples

/agent-brain:agent-brain-types

Execution

Display all available file type presets:

agent-brain types list

# JSON output for scripting
agent-brain types list --json

Expected Output

Preset       Extensions
python       *.py, *.pyi, *.pyw
javascript   *.js, *.jsx, *.mjs, *.cjs
typescript   *.ts, *.tsx
go           *.go
rust         *.rs
java         *.java
csharp       *.cs
c            *.c, *.h
cpp          *.cpp, *.hpp, *.cc, *.hh
web          *.html, *.css, *.scss, *.jsx, *.tsx
docs         *.md, *.txt, *.rst, *.pdf
text         *.md, *.txt, *.rst
pdf          *.pdf
code         *.py, *.pyi, *.pyw, *.js, *.jsx, ...

Use with: agent-brain index <path> --include-type <preset>

Output

Show the preset table and explain how to use presets with the index command. Provide examples of combining presets:

# Index only Python files
agent-brain index ./src --include-type python

# Index Python and documentation files
agent-brain index ./project --include-type python,docs

# Index all code files
agent-brain index ./repo --include-type code

# Combine presets with custom patterns
agent-brain index ./project --include-type typescript --include-patterns "*.json"

Notes

  • Presets can be combined with commas: --include-type python,docs
  • Presets can be combined with --include-patterns for custom patterns
  • The code preset is a union of all language presets
  • These presets are local (no server connection required)
  • Use agent-brain index --help to see all indexing options

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.

agent-brain-types is a command published in the GitHub repository SpillwaveSolutions/agent-brain (117 stars, last pushed 2d ago), licensed MIT. It adds 12 tokens to every session and 549 once invoked, about $0.0001 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.
