Reads your Claude Code transcripts and scores your interaction quality across 8 axes using an LLM-as-judge rubric. Tracks improvement over time. Surfaces the single biggest thing you can change to get more value from AI coding tools.

Install

npm install -g ai-coding-coach

Or run without installing:

npx ai-coding-coach score

Usage

# Score your most recent session
ai-coding-coach score

# Score a specific transcript
ai-coding-coach score --path ~/.claude/projects/my-project/abc123.jsonl

# View history
ai-coding-coach history

# Open the dashboard
ai-coding-coach dashboard

# Run eval harness (rubric stability testing)
ai-coding-coach eval --provider bedrock

Claude Code skill

A /coach skill is included for direct integration with Claude Code. To install:

mkdir -p ~/.claude/skills/coach
cp $(npm root -g)/ai-coding-coach/skill/coach.md ~/.claude/skills/coach/SKILL.md

Then use /coach in any Claude Code session to score your last session inline.

Provider setup

The scoring engine needs an LLM. Pick one:

Provider	Setup	Cost
Anthropic API	`export ANTHROPIC_API_KEY=sk-ant-...`	~$0.05/score
AWS Bedrock	`aws configure`	~$0.03/score
Claude Code CLI	Install Claude Code (free with Max)	$0

Auto-detection tries them in that order. Override with --provider <name>.

Scoring rubric

8 axes, scored 1-10:

Task Decomposition - Do you break work into steps?
Context Discipline - Do you scope context appropriately?
Verification Behaviour - Do you define pass/fail criteria?
Evidence-Seeking - Do you demand proof?
Plan-Before-Code - Do you plan before implementing?
Trust Calibration - Do you critically review AI output?
Session Hygiene - Do you manage context window effectively?
Yegge Level - Where are you on the AI adoption ladder (L1-L8)?

Each score comes with a confidence level, evidence citation, and actionable suggestion.

Example output

Session Score: 7.8/10 (L6 - AI-first)

 Task Decomposition    ████████░░  8/10  high
 Context Discipline    ███████░░░  7/10  high
 Verification          ████████░░  8/10  high
 Evidence-Seeking      ████████░░  8/10  medium
 Plan-Before-Code      ███████░░░  7/10  medium
 Trust Calibration     █████████░  9/10  high
 Session Hygiene       ███████░░░  7/10  high
 Yegge Level           ██████░░░░  L6    high

Top suggestion: Define acceptance criteria before implementation.
When you say "add X", also say "it passes when Y".

Eval harness

Validates rubric stability across transcripts:

# Create eval-manifest.json with paths to 20 transcripts
ai-coding-coach eval --provider bedrock --runs 3

# Save baseline for regression detection
ai-coding-coach eval --provider bedrock --save-baseline

Pass criteria:

Score std dev < 1.5 per axis across 3 runs of same transcript
No axis consistently scores 1 or 10 (floor/ceiling problem)
