### Added
|
||||
|
||||
- **Skills 2.0 — Taxonomie, Evals et Lifecycle** (`guide/ultimate-guide.md` §5.0, §5.X, §5.Y) — 3 nouveaux blocs : taxonomie Capability Uplift vs Encoded Preference, Skill Lifecycle (Catch Regressions + Spot Outgrowth + retirement checklist), Skill Evals (Benchmark Mode / A/B Testing / Trigger Tuning). Tableau "What Makes a Good Skill?" enrichi (colonne Expected Lifespan). `guide/cheatsheet.md` + `machine-readable/llms.txt` mis à jour. 3 nouvelles questions quiz landing (019-021).

# Resource Evaluation: Vitals — Codebase Health Plugin
|
||||
|
||||
**Date**: 2026-03-06
|
||||
**Evaluator**: Claude (Sonnet 4.6) via /eval-resource
|
||||
**Source**: LinkedIn post (text) + GitHub repo
|
||||
**GitHub**: https://github.com/chopratejas/vitals
|
||||
**Author**: Tejas Chopra
|
||||
**Score**: 3/5 (Pertinent)
|
||||
**Decision**: Integrated into guide/ultimate-guide.md §8.5
|
||||
|
||||
---
|
||||
|
||||
## Summary
|
||||
|
||||
Vitals is a Claude Code plugin (v0.1 alpha, MIT, Python stdlib + git) that identifies code hotspots using a composite metric: `git churn × structural complexity × coupling centrality`. Claude then reads the flagged files and provides semantic diagnosis rather than raw metrics.
|
||||
|
||||
**Key points**:
|
||||
1. Computes churn × complexity × coupling centrality — no linter does this combination
|
||||
2. Claude reads top-flagged files: diagnosis says "this class handles routing, caching, rate limiting, AND metrics in 7,137 lines" not just "high complexity"
|
||||
3. Background tracking of AI-generated edits via PostToolUse hooks
|
||||
4. Zero dependencies, zero API keys — Python stdlib + git only
|
||||
5. v0.1 alpha: core detection works, trend tracking planned for v0.2+
|
||||

## Evaluation Scoring
|
||||
|
||||
| Criterion | Score | Notes |
|
||||
|-----------|-------|-------|
|
||||

| **Authority** | 2/5 | New author, v0.1 alpha, limited community validation |
|
||||
| **Accuracy** | 4/5 | Methodology sound; post had one misquoted stat (see fact-check) |
|

## Gap Analysis
|
||||
|
||||
### Already Covered in Guide
|
||||
|
||||
| Concept | Guide Coverage | Location |
|
||||
|---------|----------------|----------|
|
||||
| AI code quality degradation | GitClear stats, comprehension debt | quiz/questions, learning-with-ai.md |
|
||||
| Plugin system | Full section 8.5 | ultimate-guide.md:12015 |
|
||||
| SE-CoVe plugin example | Full documentation | examples/plugins/se-cove.md |
|
||||
|
||||
### What's New
|
||||
|
||||
- **Hotspot identification methodology**: `churn × complexity × coupling centrality` as a composite metric — not in guide
|
||||
- **Concrete tool** that maps the "AI code debt" problem to actionable file-level output
|
||||
- **Bus factor / knowledge risk** metric — unique angle not documented
|
||||
- **PostToolUse hook for AI provenance tracking** — interesting hook usage pattern

||||

## Fact-Check Results
|
||||
|
||||
| Claim | Verified | Note |
|
||||
|-------|----------|------|
|
||||
| "41% of code is now AI-generated" | ❌ INCORRECT | GitClear actual stat: AI code has **41% higher churn**, not 41% of code volume. Post misquotes the stat. |
|
||||
| "Refactoring collapsed from 25% to under 10%" | ✅ | GitClear 211M lines, 2021–2025, confirmed via Perplexity |
|
||||
| "GitClear's research on 211M lines" | ✅ | Confirmed |
|
||||
| "METR's RCT showed 20% faster perception, 19% slower reality" | ✅ | METR RCT (Jul 2025, 16 devs, 246 tasks): estimated +20-24%, actual -19% |
|
||||
| "Zero dependencies, Python stdlib + git" | ✅ | README confirms |
|
||||
| v0.1 alpha status | ✅ | README confirms |
|
||||
|
||||
**Key correction**: The post's "41% of code is now AI-generated" is a misquote. The guide documents this correctly as "AI-generated code has 41% higher churn."
|
||||
|
||||

|
||||
|
||||
## Integration Actions
|
||||
|
||||
1. ✅ Added "Featured Community Plugins" subsection to `guide/ultimate-guide.md` §8.5 (~line 12385)
|
||||
- Vitals section with install commands, use cases
|
||||
- SE-CoVe section (updated from existing coverage)
|
||||
- Vitals vs. SE-CoVe comparison table
|
||||
2. ✅ Updated `machine-readable/reference.yaml` with Vitals entry (install, command, purpose, status)

**Rule of thumb**: If Claude makes a mistake twice because of missing context, add that context to CLAUDE.md. Don't preemptively document everything — and don't ask Claude to generate it for you either. Auto-generated CLAUDE.md files tend to be generic, bloated, and filled with things Claude already detects on its own.
|
||||
|
||||
**When your project grows**, structure CLAUDE.md around three layers (community-validated pattern):
|
||||
|
||||
```markdown
|
||||
## WHAT — Stack & Structure
|
||||
- Runtime: Node.js 20, pnpm 9
|
||||
- Framework: Next.js 14 App Router
|
||||
- DB: PostgreSQL via Prisma ORM
|
||||
- Key dirs: src/app/ (routes), src/lib/ (shared), src/components/
|
||||
|
||||
## WHY — Architecture Decisions
|
||||
- App Router chosen for RSC + streaming support
|
||||
- Prisma over raw SQL: type safety + migration tooling
|
||||
- No Redux: server state via React Query, local state via useState
|
||||
|
||||
## HOW — Working Conventions
|
||||
- Run: `pnpm dev` | Test: `pnpm test` | Lint: `pnpm lint --fix`
|
||||
- Commits: conventional format (feat/fix/chore)
|
||||
- PRs: always include tests for new features
|
||||

> **New Feature (Feb 2026)**: Claude Code now automatically captures and recalls important context across sessions without manual CLAUDE.md editing.
|
||||
> **Not to be confused with Claude.ai memory**: Claude.ai (the web interface) launched a separate memory feature in Aug 2025 for Teams, Oct 2025 for Pro/Max. That's a different system — it stores conversation preferences in your claude.ai account. Claude Code's auto-memory is a local, per-project feature managed via the `/memory` command.
|

|

Claude Code automatically saves useful context across sessions without manual CLAUDE.md editing. Introduced in v2.1.59 (Feb 2026), shared across git worktrees since v2.1.63.
|
||||
|
||||
**How it works**:
|
||||
- Claude automatically identifies key information during conversations (preferences, decisions, patterns)
|
||||
- Memories are stored per-project, separate from CLAUDE.md files
|
||||
- Recalled automatically in future sessions relevant to that project
|
||||
- Opt-in feature — enable in settings
|
||||
- Claude identifies key context during conversations (decisions, patterns, preferences)
|
||||
- Stored in `.claude/memory/MEMORY.md` (project) or `~/.claude/projects/<path>/memory/MEMORY.md` (global)
|
||||
- Automatically recalled in future sessions for the same project
|
||||
- Manage with `/memory`: view, edit, or delete stored entries

## 5.0 Two Kinds of Skills
|

|
||||
> **New in March 2026**: Anthropic's Skill Creator update formalizes a taxonomy that changes how you design, test, and eventually retire skills. Sources: ainews.com, mexc.co, claudecode.jp — not yet reflected in the official `llms-full.txt`.
|
||||
|
||||
Not all skills age the same way. The type you're building determines how you write it, how you test it, and when to retire it.
|
||||
|
||||
| | Capability Uplift | Encoded Preference |
|
||||
|---|---|---|
|
||||
| **What it does** | Fills a gap the base model can't handle consistently | Sequences existing capabilities your team's specific way |
|
||||
| **Examples** | Precise PDF text placement, custom code patterns | NDA review checklist, weekly status update workflow |
|
||||
| **Durability** | Fades as the model improves | Stays durable as long as the workflow is relevant |
|
||||
| **Retirement signal** | Model passes the eval without the skill | Workflow changes or becomes irrelevant |
|
||||
| **Eval approach** | A/B test: with vs. without the skill | Fidelity check: does it follow the sequence correctly? |
|
||||
|
||||
**Capability Uplift** teaches Claude something it genuinely can't do well on its own — yet. High value today, but carries a maintenance debt: as Claude improves, these skills may become redundant. Evals tell you when that happens before a user does.
|
||||
|
||||
**Encoded Preference** encodes your team's specific way of doing something Claude already knows how to do. An NDA review follows your legal team's criteria, not a generic checklist. These skills don't compete with model improvements — they capture workflow decisions that are yours to make, and stay relevant as long as your process does.
|
||||
|
||||
> **Practical implication**: When building a Capability Uplift skill, budget time for evals. When building an Encoded Preference skill, budget time for keeping the workflow description accurate as your process evolves.

|
||||
## 5.X Skill Lifecycle & Retirement
|
||||
|
||||
Skills have a lifecycle. Treating them like permanent artifacts leads to skill rot: dead code in `.claude/skills/` that consumes tokens and provides no value.
|
||||
|
||||
Two patterns govern when to act:
|
||||
|
||||
```
|
||||
CATCH REGRESSIONS SPOT OUTGROWTH
|
||||
───────────────── ──────────────
|
||||
Model Evolves Model Improves
|
||||
↓ ↓
|
||||
Skill Drifts Skill Passes Alone
|
||||
↓ (without help)
|
||||
Eval Alerts ↓
|
||||
(early signal) Skill Retired
|
||||
↓ (no longer needed)
|
||||
Fix or Retire
|
||||
```
|
||||
|
||||
**Catch Regressions**: Your skill worked last month. The model updated. Now it behaves differently. Without evals, you discover this when a user reports a problem. With evals, you catch it before the failure reaches anyone.
|
||||
|
||||
**Spot Outgrowth**: You built a Capability Uplift skill to cover a gap. Six months later, Claude handles that gap natively. Run the eval without the skill — if it passes, the skill is no longer needed. Remove it to reduce context load and maintenance overhead.
|
||||
|
||||
### Retirement Decision Checklist
|
||||
|
||||
- [ ] **Run eval without the skill**: does Claude pass on its own?
|
||||
- [ ] **Check last activation date**: when did this skill last fire in practice?
|
||||
- [ ] **Check workflow accuracy**: for Encoded Preference skills, has the underlying process changed?
|
||||
- [ ] **Archive before deleting**: move to `.claude/skills/archive/` with a dated note explaining why it was retired
|
||||
|
||||

|
||||
|
||||
## 5.Y Skill Evals
|
||||
|
||||
Skill evals move quality from "seems to work" to "know it works." They're the testing layer that makes skills production-grade.
|
||||
|
||||
> **Available via**: Skill Creator plugin (Anthropic GitHub) for Claude Code users. Live on Claude.ai and Cowork as of March 2026. Sources: ainews.com, mexc.co — not yet in official `llms-full.txt`.
|
||||
|
||||
### How It Works
|
||||
|
||||
```
|
||||
Skill → Test Prompts + Files
|
||||
↓
|
||||
Expected Output (what good looks like)
|
||||
↓
|
||||
Run Evals
|
||||
↓
|
||||
Pass ✓ / Fail ✗
|
||||
↓
|
||||
Improve skill → Re-run
|
||||
```
|
||||
|
||||
You define three things: test prompts (realistic inputs that trigger the skill), expected outputs (description of what "good" looks like — not exact string matching), and a pass rate threshold. Claude executes the skill against each test case and judges the output.
|
||||
|
||||
Results report: pass rate, elapsed time, token usage per test case.
|
||||
|
||||
### The Three Eval Tools
|
||||
|
||||
**Benchmark Mode** — tracks pass rates, elapsed time, and token usage across model updates. Runs tests in parallel with clean, isolated contexts (no cross-contamination between cases). Use this to detect regressions automatically when Claude updates.
|
||||
|
||||
**A/B Testing (Comparator Agents)** — blind head-to-head comparison between two versions of a skill. Version A vs. Version B, judged without knowing which is which. Removes confirmation bias from skill improvement decisions.
|
||||
|
||||
**Trigger Tuning (Description Optimizer)** — analyzes your skill's `description` field and suggests improvements to reduce false positives (skill fires when it shouldn't) and false negatives (skill doesn't fire when it should). Anthropic's internal test: 5 of 6 document-creation skills showed improved triggering accuracy after optimization. [Source: claudecode.jp — directional, not independently verified]
|
||||
|
||||
### Two Uses of Evals
|
||||
|
||||
| Use Case | When | Action |
|
||||
|----------|------|--------|
|
||||
| **Catch Regressions** | After model updates | Run benchmark → alert if pass rate drops |
|
||||
| **Spot Outgrowth** | Periodically for Capability Uplift skills | Run eval *without* the skill → if it passes, retire |
|
||||
|
||||
### Practical Eval Structure
|
||||
|
||||
```
|
||||
.claude/skills/my-skill/
|
||||
├── SKILL.md
|
||||
└── tests/ ← Eval directory
|
||||
├── test-01-basic.md # Prompt + expected output description
|
||||
├── test-02-edge-case.md # Edge case coverage
|
||||
└── benchmark-config.md # Pass rate threshold, token budget
|
||||
```
|
||||
|
||||
### Eval Design Principles
|
||||
|
||||
- **One behavior per test**: don't combine multiple assertions — failures become ambiguous
|
||||
- **Include edge cases**: test the inputs that made the skill necessary in the first place
|
||||
- **Define "good" precisely**: vague expected outputs make eval judgments unreliable
|
||||
- **Set a pass rate threshold**: 80% is a reasonable starting point; adjust for criticality

||||
### Featured Community Plugins
|
||||
|
||||
Two community plugins address complementary problems that AI-assisted development creates: **code quality drift** (accumulation of poorly-structured AI-generated code) and **hallucination in generated solutions**.
|
||||
|
||||
#### Vitals — Codebase Health Detection
|
||||
|
||||
**Problem solved**: AI tools write code faster than teams can maintain it. GitClear's analysis of 211M lines shows refactoring collapsed from 25% to under 10% of all changes (2021–2025). Vitals identifies which files are most likely to cause problems next — before they do.
|
||||
|
||||
**How it works**: Computes `git churn × structural complexity × coupling centrality` to rank hotspots. Not just "this file is complex" but "this complex file changed 49 times in 90 days and 63 other files break when it does."
|
||||
|
||||
```bash
|
||||
# Install (two commands in Claude Code)
|
||||
/plugin marketplace add chopratejas/vitals
|
||||
/plugin install vitals@vitals
|
||||
|
||||
# Scan from repo root
|
||||
/vitals:scan
|
||||
|
||||
# Scope options
|
||||
/vitals:scan src/ # Specific folder
|
||||
/vitals:scan --top 20 # More results (default: 10)
|
||||
/vitals:scan src/auth --top 5
|
||||
```
|
||||
|
||||
**What you get**: Claude reads the flagged files and gives semantic diagnosis. Instead of "high complexity," you get: "this class handles routing, caching, rate limiting, AND metrics in 7,137 lines — extract each concern."
|
||||
|
||||
**Status**: v0.1 alpha. MIT. Zero dependencies (Python stdlib + git). Works on any repo.
|
||||
|
||||

|
||||
|
||||
#### SE-CoVe — Chain-of-Verification
|
||||
|
||||
**Problem solved**: AI-generated code contains subtle errors that survive code review because both the AI and the reviewer follow the same reasoning path. SE-CoVe breaks this by running an independent verifier that never sees the initial solution.
|
||||
|
||||
**Research foundation**: Adaptation of Meta's Chain-of-Verification methodology (Dhuliawala et al., ACL 2024 Findings — [arXiv:2309.11495](https://arxiv.org/abs/2309.11495)).
|
||||
|
||||
**How it works** — 5-stage pipeline:
|
||||
|
||||
1. **Baseline** — Claude generates initial solution
|
||||
2. **Planner** — Creates verification questions from the solution's claims
|
||||
3. **Executor** — Answers questions without seeing the baseline (prevents confirmation bias)
|
||||
4. **Synthesizer** — Compares findings, surfaces discrepancies
|
||||
5. **Output** — Produces verified solution
|
||||
|
||||
```bash
|
||||
# Install (two separate commands — marketplace limitation)
|
||||
/plugin marketplace add vertti/se-cove-claude-plugin
|
||||
/plugin install chain-of-verification
|
||||
|
||||
# Use
|
||||
/chain-of-verification:verify <your question>
|
||||
/ver<Tab> # Autocomplete available
|
||||
```
|
||||
|
||||
**Trade-offs**: ~2x token cost, reduced output volume. Worth it for security-sensitive code, complex debugging, and architectural decisions — not for rapid prototyping or simple fixes.
|
||||
|
||||
**Source**: [vertti/se-cove-claude-plugin](https://github.com/vertti/se-cove-claude-plugin) — v1.1.1, MIT
|
||||
|
||||
#### Vitals vs. SE-CoVe — Which to Use
|
||||
|
||||
These tools solve different problems at different stages of the development cycle:
|
||||
|
||||
| | Vitals | SE-CoVe |
|
||||
|--|--------|---------|
|
||||
| **When** | Maintenance / weekly review | Per-task generation |
|
||||
| **Problem** | Accumulated code debt | Per-solution accuracy |
|
||||
| **Input** | Entire git history | A specific question |
|
||||
| **Output** | Ranked hotspot files + diagnosis | Verified answer |
|
||||
| **Token cost** | Low (Python analysis + Claude reads top files) | ~2x standard generation |
|
||||
| **Best for** | "Which file is going to break?" | "Is this solution correct?" |
|
||||
| **Status** | v0.1 alpha | v1.1.1 stable |
|
||||
|
||||
**Complementary workflow**: Run Vitals weekly to identify which areas of the codebase need attention, then use SE-CoVe when asking Claude to refactor or fix those hotspot files.
