brewtools:text-human

Text Humanizer

Detect and remove AI-generated artifacts from code and documentation. Process commits, files, or folders with parallel sub-agents.

Language References

Language	Reference	Load When
Java/Kotlin	@reference/java.md	*.java, *.kt, *.groovy, Spring, Maven/Gradle
TypeScript/JS/React	@reference/typescript.md	*.ts, *.tsx, *.js, *.jsx, Node.js, React
Python	@reference/python.md	*.py, Django, FastAPI, Flask

Multi-language projects: Load ALL relevant references.

Argument

First token = scope (required):

Input	Action
None	Use AskUserQuestion: "What to humanize?" Options: "Commit hash (git diff)" / "File path" / "Folder path"
Commit hash (7+ hex)	Process all text files from commit
File path	Process single file
Folder path	Process all files in folder
"entire project"	Use AskUserQuestion: "Too broad — specify scope." Options: "Specific folder" / "File pattern (e.g. src/**/*.java)"

Everything after first token = custom prompt (optional). Free-form text, no quotes needed. Overrides or extends default humanization rules for this run. Passed to every sub-agent prompt.

Custom Prompt Handling

1. Parse: split args into scope (first token) and customPrompt (rest)
2. If customPrompt is present, prepend it to every sub-agent Task prompt as:

   CUSTOM INSTRUCTIONS (highest priority, override defaults):
   <customPrompt>
   

3. Custom prompt wins over default rules on conflict

Architecture

Orchestrator -> Detect Language -> Load Reference -> Analyze -> Classify -> Split (3-10 blocks) -> Parallel Task agents -> Aggregate

Phase 1: Scope Analysis

Commit Mode

Process all text files from commit. No extension filtering: git diff --name-only <hash>^..<hash>

File Inclusion Rules

Include	Exclude
Source code (*.java, *.kt, *.py, *.ts, *.js, etc.)	Binary files (*.class, *.pyc, *.exe)
Config (*.xml, *.yaml, *.yml, *.json, *.toml)	Images (*.png, *.jpg, *.gif, *.ico)
Docs (*.md, *.txt, *.rst)	Archives (*.zip, *.tar, *.gz)
Build files (pom.xml, package.json, pyproject.toml)	Generated (target/, build/, dist/, node_modules/)
SQL (*.sql, *.ddl)	Lock files, IDE files

Path Mode

find <path> -type f \( -name "*.java" -o -name "*.py" -o -name "*.ts" -o -name "*.js" -o -name "*.md" \) | grep -v -E "(target/|node_modules/|\.git/|build/|dist/|__pycache__/)"

Block Count

Files	Lines	Blocks
1-2	<200	1 (direct)
3-5	<500	3
6-10	500-1500	5
11-20	1500-3000	7
21+	3000+	10

Single file: process directly without Task delegation.

Phase 2: File Classification

Haiku (Simple)

Type	Patterns
Config	*.properties, *.yaml, *.yml, *.toml, *.ini
Data	*.json, *.csv
Text	*.txt, *.md
Simple SQL	Single CREATE/ALTER, no CTEs/subqueries
Small files	<50 lines, no logic

Sonnet (Complex)

Type	Patterns
Source with logic	Business logic, algorithms
Tests	Test files for any framework
Complex SQL	CTEs, window functions, JOINs, subqueries
Config classes	Framework configuration

Note: See language-specific references for detailed classification rules.

Phase 3: Block Formation

Group files by type, complexity (avoid mixed haiku/sonnet), line count balance. Keep related files together (same package/directory).

Data files block: YAML, JSON, CSV with comments → haiku for unicode fixes

Phase 4: Parallel Execution

Launch all Task calls in single message for true parallelism.

Task(subagent_type="developer", model="haiku", prompt="> **Context:** BT_PLUGIN_ROOT is available in your context (injected by pre-task.mjs hook).\n\n[CUSTOM_INSTRUCTIONS_IF_ANY]\nBlock 1: [files] [rules] Return JSON")
Task(subagent_type="developer", model="sonnet", prompt="> **Context:** BT_PLUGIN_ROOT is available in your context (injected by pre-task.mjs hook).\n\n[CUSTOM_INSTRUCTIONS_IF_ANY]\nBlock 2: [files] [rules] Return JSON")

If custom prompt was provided, prepend to EVERY sub-agent prompt (after the Context line):

> **Context:** BT_PLUGIN_ROOT is available in your context (injected by pre-task.mjs hook).

CUSTOM INSTRUCTIONS (highest priority, override defaults):
<user's custom prompt text>
---

<output_format> { "files_processed": N, "changes": [{"file": "path", "removed_comments": N, "fixed_unicode": N, "simplified_docs": N}] } </output_format>

Phase 5: Aggregation

Collect JSON results from all agents → merge statistics → generate unified report.

<humanization_rules>

AI Artifacts (Universal)

Pattern	Action
// Added by AI, // Claude suggestion, // AI-generated, // Generated by	Delete
# Added by AI, # Claude suggestion	Delete
/* Suggested by */	Delete block
AI-invented issue numbers (BUG-001, FIX-123, ISSUE-1)	Delete
Unicode long dash (U+2014)	Replace → --
Unicode arrows (→, ←, ⇒)	Replace → ->, <-, =>
Unicode bullets (•, ◦)	Replace → - or *
Unicode quotes (" " ' ')	Replace → " or '

Real vs Fake Issue References

Keep project-specific ticket patterns (INTELDEV-XXXXX, JIRA-XXXXX, GH-XXX). Remove generic AI-invented patterns (BUG-001, FIX-123, ISSUE-42).

Documentation Cleanup (General Principles)

Remove	Keep
Private/internal function docs	Public API documentation
Test file documentation	Complex algorithm explanation
Obvious classes/functions (name = purpose)	Non-obvious behavior/side effects
Trivial parameter docs (restates name)	@throws/Raises with conditions
Trivial return docs (restates function)	External API contracts

Key Rule: Never convert block docs to inline comments. Delete unnecessary docs entirely; for useful descriptions with trivial params, strip params and keep description.

Comments (Universal)

Keep WHY, remove WHAT.

Remove	Keep
// Initialize the list	// Retry 3x due to flaky external API
// Loop through items	// Uses UTC to match database timezone
// Check if null	// Thread-safe: synchronized on class lock
Stale // TODO: refactor this	// HACK: workaround for <issue-link>

Formatting (Universal)

Issue	Fix
/* single line */	// single line or # single line
3+ blank lines	Max 2
Trailing whitespace	Remove
Mixed tabs/spaces	Spaces

</humanization_rules>

File Type Rules

Type	Rules
Source code	Full doc cleanup per language reference
Test files	Remove all docs, keep test descriptions
SQL/XML	Preserve structural comments
Markdown	Remove AI disclosures, fix unicode
YAML/Properties	Fix unicode, keep config explanations
JSON/CSV	Check for comments with unicode, usually skip

YAML/Data Files

Check for unicode in comments. Section comments are valuable.

Action	Example
FIX	# Lane 90001→10001 → # Lane 90001->10001
KEEP	# ===== VAN loads for test =====
SKIP	Pure data without comments

SQL/XML Comments

Structural comments are valuable. Analyze neighboring files first.

Action	Example
KEEP	Section headers -- ============ TABLES ============
KEEP	Block separators <!-- ===== Mappers ===== -->
KEEP	Column/field documentation
REMOVE	Exact duplicates, AI markers

---

Custom Prompt Mode

Custom prompt overrides or extends default rules. Use for:

• Restricting scope: "only remove AI artifacts, don't touch docs"
• Adding rules: "also remove all @author tags"
• Excluding files: "skip test files"
• Style reference: "use style from src/main/Service.java as reference"

Output Format

## Humanization Report

### Execution Summary
| Metric | Value |
|--------|-------|
| Total files | N |
| Blocks | M |
| Haiku/Sonnet | X/Y |

### Block Results
[Per-block tables with file metrics]

### Totals
| Metric | Count |
|--------|-------|
| Files processed | N |
| Comments removed | X |
| Docs simplified | Y |
| Unicode fixed | Z |

Best Practices

• Load language reference first
• Process all commit files (include yaml/data files)
• Check yaml for unicode (comments may have arrows)
• Preserve valuable comments (they add context)
• Skip binaries (avoid corruption)
• Honor style reference if provided
• Keep public API docs
• Group files by complexity
• Launch agents in parallel

Error Handling

Error	Action
Agent timeout	Continue with other blocks
File read error	Skip, note in report
Binary file	Skip, note in report
No changes	Report "No humanization required"
