doc-classifier

name	doc-classifier
description	This skill should be used when the user asks to "classify docs", "what documentation do I need", "analyze doc needs", "documentation audit", or needs to determine what documentation types are needed based on code changes. Analyzes git commits and feature scope to return structured classification data.

doc-classifier Skill

Classify documentation needs based on code changes.

Description

Analyzes git commits, file changes, and feature scope to determine what documentation types are needed. Returns structured classification data.

Inputs

Input	Type	Description
feature_name	string	Optional feature name to analyze
commit_range	string	Git commit range (default: HEAD~10)
format	string	Output format: json, summary, actions

Outputs

{
  "feature": "session tracking",
  "scope": {
    "commands": ["sessions live", "sessions current", "sessions task"],
    "modules": ["src/aiterm/sessions/"],
    "hooks": ["session-register", "session-cleanup"],
    "files_changed": 23,
    "commits": 15
  },
  "classification": {
    "guide": { "score": 8, "needed": true, "reason": "New module with 5 CLI commands" },
    "refcard": { "score": 5, "needed": true, "reason": "5 new commands" },
    "gif_demo": { "score": 6, "needed": true, "reason": "User-facing CLI workflow" },
    "mermaid": { "score": 7, "needed": true, "reason": "Hook-based event system" }

}

Scoring Algorithm

Base Scores

Factor	Guide	Refcard	GIF	Mermaid
New command (each)	+1	+1	+0.5	+0
New module	+3	+1	+1	+2
New hook	+2	+1	+1	+3
Multi-step workflow	+2	+0	+3	+2
Config changes	+0	+2	+0	+0
Architecture change	+1	+0	+0	+3
User-facing CLI	+1	+1	+2	+0

Threshold

• Score >= 3: needed
• Score >= 5: high priority
• Score >= 7: essential

Detection Logic

Command Detection

# Find new @app.command decorators
git diff HEAD~10 --name-only | xargs grep -l "@app.command"

# Parse command names
grep -E "@app\.command\(|def \w+\(" src/*/cli/*.py

Module Detection

# New directories with __init__.py
git diff --diff-filter=A HEAD~10 --name-only | grep "__init__.py"

Hook Detection

# Hook-related files
git diff HEAD~10 --name-only | grep -E "hook|event"

# Hook configuration
grep -E "SessionStart|Stop|PreToolUse" ~/.claude/settings.json

Workflow Detection

# Subcommand groups (Typer)
grep "typer.Typer()" src/*/cli/*.py

# Multi-step docs
grep -E "Step [0-9]" docs/**/*.md

Usage Examples

From /craft:docs:analyze

# Internal call
classification = doc_classifier(
    feature_name="session tracking",
    commit_range="HEAD~15"
)

if classification["guide"]["needed"]:
    # Generate guide
    pass

Standalone

/skill doc-classifier "session tracking" --format json
