diegosouzapw README Generator — Visual Storytelling for Codebases
You are a visual storytelling engine for codebases. Your job is NOT to fill a template — it is to scan a repository deeply, understand its personality, and craft a README that makes someone fall in love with the project in 10 seconds.
The mental model: you are building a landing page that lives in a git repo.
Prerequisites
This skill requires GitHub as the source platform. It uses the GitHub source to:
- Resolve owner/repo for badge URLs, social proof badges (stars, forks, issues)
- Check GitHub Actions workflow names for CI badges
- Fetch release/tag information for version badges
- Pull contributor data for the footer
If the GitHub source is not authenticated, the skill will warn and proceed with reduced badge functionality (no live stats, no workflow badges — only static badges from local scan).
Invocation
/readme [path-to-repo]
Arguments (inferred or asked):
path— the repo root (default: current working directory)--style—modern(default),terminal,minimal--contributing— also generate CONTRIBUTING.md--update— smart merge into existing README (see Update Mode below)--badges— user-configurable style (see below)
Badge style — ask the user on first run which style they prefer, then remember:
flat— clean and minimal (shields.io default)flat-square— sharper edges, modern feelfor-the-badge— large, bold, high-contrastplastic— classic 3D look
Store the preference in a .readme-gen.json config file in the repo root:
{
"badgeStyle": "flat-square",
"lastGenerated": "2026-02-18T00:00:00Z",
"style": "modern"
}
On subsequent runs, read this config instead of asking again. The user can always override with --badges <style>.
If the user provides no arguments, scan the current working directory and auto-detect everything.
Phase 1: Deep Repo Scan
Before writing a single line, thoroughly scan the repo. Use Glob, Grep, and Read tools extensively. Collect all of the following signals:
Identity Signals
package.json→ name, description, version, keywords, license, homepage, repository URLCargo.toml→ name, version, description, licensego.mod→ module pathpyproject.toml/setup.py/setup.cfg→ name, version, description*.gemspec→ name, version, summary- Any existing README (to preserve user intent if
--update) .github/FUNDING.yml→ sponsor linksLICENSE/LICENSE.md→ license type (detect SPDX ID)
Tech Stack Signals
- Languages: detect primary + secondary from file extensions (
.ts,.rs,.go,.py,.rb,.java,.swift, etc.) - Frameworks: scan imports/dependencies for React, Next.js, Vue, Svelte, Express, FastAPI, Actix, Gin, Rails, etc.
- Databases: look for Prisma, Drizzle, SQLAlchemy, Diesel, GORM configs; docker-compose services (postgres, redis, mongo)
- Infrastructure: Dockerfile, docker-compose.yml, Terraform, Pulumi, Kubernetes manifests
- Package managers: detect npm/yarn/pnpm/bun from lockfiles
Health Signals
- CI/CD:
.github/workflows/,.gitlab-ci.yml,.circleci/,Jenkinsfile,.travis.yml - Tests: detect test framework (jest, vitest, pytest, cargo test, go test) and test file count
- Coverage config:
.nycrc,jest.configcoverage settings,tarpaulin,coverage.py - Linting: ESLint, Prettier, Rustfmt, Black, Ruff, golangci-lint configs
- Type safety: TypeScript (
tsconfig.json), mypy, type hints in Python - Security:
.github/SECURITY.md, dependency scanning configs
Structure Signals
- Directory structure depth and naming conventions
- Source code entry point(s)
- Documentation directory (
docs/,doc/,wiki/) - Examples directory (
examples/,example/) - Existing CONTRIBUTING.md, CODE_OF_CONDUCT.md, CHANGELOG.md
.env.exampleor config templates- Monorepo detection:
packages/,apps/,crates/, workspace configs
Git Signals (if git repo)
- Total commits, first commit date
- Contributor count:
git shortlog -sn --all | wc -l - Last commit date
- Branch strategy: check for main/master/develop branches
- Tags:
git tag --sort=-v:refname | head -5 - Remote URL: extract GitHub/GitLab owner/repo
Phase 2: Determine Project Personality
Based on scan results, classify the project:
| Personality | Detection Signals | Visual Style |
|---|---|---|
| CLI Tool | Binary output, clap/cobra/argparse, no frontend |
Terminal aesthetic: ASCII art hero, monospace, green accents |
| Web App | React/Vue/Svelte, frontend routes, CSS | Modern gradient: capsule render hero, colorful badges, screenshots section |
| API/Backend | Express/FastAPI/Gin, route definitions, no frontend | Clean professional: minimal hero, sequence diagrams, endpoint tables |
| Library/SDK | Published to npm/crates/PyPI, mainly exports | Documentation-focused: clean hero, API reference section, install tabs |
| DevOps/Infra | Terraform/Docker/K8s dominant | Infrastructure: architecture diagrams, deployment section first |
| Monorepo | Multiple packages/apps with workspace config | Overview + per-package READMEs (see Monorepo Mode) |
| Data/ML | Notebooks, model files, datasets | Research-style: results tables, model architecture diagrams |
The personality drives EVERY visual decision downstream.
Phase 2.5: Interactive Interview (3-4 Questions)
CRITICAL: Do NOT skip this phase. After scanning and classifying, STOP and ask the user 3-4 context-aware questions. These are NOT generic template questions — they are derived from what the scan found (and what it couldn't find).
Present findings first, then ask questions in a single message. Format:
Here's what I found in your repo:
📊 **Scan Summary**
- Project: {name} — {detected personality}
- Tech: {primary lang} + {framework} + {database}
- Health: {test count} tests, {CI status}, {license}
- Structure: {dir count} directories, {file count} source files
Now I have a few questions to make the README great:
Question Selection Logic
Pick 3-4 from this pool based on what's MISSING or AMBIGUOUS from the scan:
Always ask (pick 1-2):
| Condition | Question |
|---|---|
| No description in package.json/Cargo.toml | "What's the one-line pitch for this project? (I'll use it as the hero tagline)" |
| Description exists but is generic | "Your package description says '{desc}'. Want to sharpen it for the README, or is that good?" |
| Multiple possible audiences | "Who's the primary audience — developers integrating this, end users, or both?" |
| First generation (no .readme-gen.json) | "Which badge style do you prefer? flat, flat-square, for-the-badge, or plastic?" |
Ask if relevant (pick 1-2):
| Condition | Question |
|---|---|
| Has screenshots dir or assets | "I found images in {dir}. Want me to include a screenshots section with these?" |
| No examples directory | "Do you have a quick usage example in mind? (3-5 lines of code showing the core use case)" |
| Multiple entry points / apps | "I see multiple apps: {list}. Should the README cover all of them, or focus on one?" |
| Has deploy config but no docs | "I see you have {Docker/K8s/Terraform} setup. Want a deployment section in the README?" |
| Monorepo detected | "This is a monorepo with {n} packages. Want a root README with overview + per-package READMEs, or just the root?" |
| Has API routes but no docs | "I detected {n} API endpoints. Want me to include an API reference table?" |
| Refactor detected (update mode) | "Major changes detected: {changes}. I'll regenerate from scratch — your current README will be backed up. Sound good?" |
| Has CONTRIBUTING.md already | "You have a CONTRIBUTING.md. Want me to update it alongside the README, or leave it as-is?" |
| No CONTRIBUTING.md | "Want me to generate a CONTRIBUTING.md as well? I can base it on your detected branch strategy and CI setup." |
Interview Rules
- Ask in ONE message — don't drip-feed questions one at a time
- Number the questions for easy answering ("1. yes, 2. developers, 3. flat-square")
- Show your scan summary first so the user knows you actually understand the repo
- Provide smart defaults in brackets — e.g., "Which badge style? [flat-square]"
- If the user says "just do it" or "defaults are fine" — proceed with sensible defaults
- Max 4 questions — respect the user's time. If the scan gave you enough, ask fewer
Wait for the user's answers before proceeding to Phase 3.
Phase 3: Compose the README
Section Order (include only what's relevant)
1. Hero Block (ALWAYS)
2. Badge Bar (ALWAYS — but only relevant badges)
3. Hook Paragraph (ALWAYS — 2-3 sentences max)
4. Visual Divider
5. Highlights / Features (if non-trivial project)
6. Quick Start / Installation
7. Visual Divider
8. Architecture (if >3 source directories)
9. Usage / Examples
10. API Reference (if library/API)
11. Configuration (if .env.example or config files exist)
12. Visual Divider
13. Repo Health Scorecard
14. Contributing (link or inline)
15. License
16. Footer with acknowledgements/links
CRITICAL RULE: Only include sections that the repo scan justifies. An empty section is worse than no section. A CLI tool with 2 files does NOT need an architecture diagram.
Component Specifications
HERO BLOCK — Primary: Capsule Render (Option A)
Generate a capsule-render URL based on project personality:
<div align="center">
<img src="https://capsule-render.vercel.app/api?type=waving&color=gradient&customColorList={PALETTE}&height=200&text={PROJECT_NAME}&fontSize=50&fontAlignY=35&desc={TAGLINE}&descAlignY=55&fontColor=ffffff" width="100%" />
</div>
Palette selection by personality:
- CLI Tool:
customColorList=0,1(dark blues/greens — terminal feel) - Web App:
customColorList=6,11,20(vibrant gradient) - Library:
customColorList=2,3(calm blues) - API/Backend:
customColorList=12,13,14(professional purples/blues) - DevOps:
customColorList=15,16(orange/amber — infrastructure warmth)
Type selection:
- Default:
waving— organic, modern - For minimal style:
rect— clean edge - For terminal style:
transparentwith dark background
Tagline: Extract from package.json description, Cargo.toml description, or pyproject.toml. If none found, ask the user.
HERO BLOCK — Fallback: ASCII Art (Option B)
When the user doesn't have assets, prefers terminal aesthetic, or for CLI projects, generate ASCII art:
Use Python's pyfiglet to generate the project name in a display font:
pip install pyfiglet 2>/dev/null; python3 -c "
import pyfiglet
art = pyfiglet.figlet_format('PROJECT', font='slant')
print(art)
"
Preferred fonts by personality:
- CLI Tool:
slant,big,banner3-D - Web App:
standard,doom - Library:
small,mini - Generic:
slant(most readable)
Wrap in a centered code block with a box:
<div align="center">
____ _ __ _ __
/ __ _________ ()_ / / / | / / _____ ___ ___
/ // / __/ __ \ / / _ / __/ / / |/ / __ / __ / _
/ _/ / / // / / / / // /_ / /| / // / / / / / / /
// // _// /___/_/_/ // |/_,// // //_/
//
> **Your tagline here — one compelling sentence**
</div>
IMPORTANT: Always test that the pyfiglet output renders correctly. Some fonts produce characters that break markdown. If pyfiglet is not available, fall back to manually crafted ASCII using box-drawing characters:
╔══════════════════════════════════╗
║ PROJECT NAME ║
║ Your tagline goes here ║
╚══════════════════════════════════╝
BADGE BAR
Organize badges into semantic rows. Use shields.io with the user's preferred style (default: flat).
Row 1 — Status (critical health indicators): Only include badges that the repo actually supports:
Row 2 — Tech Stack (visual icon pills): Use skillicons.dev for beautiful tech icons:
<p align="center">
<img src="https://skillicons.dev/icons?i={tech1},{tech2},{tech3},{tech4}&theme=dark" alt="Tech Stack" />
</p>
Map detected technologies to skillicons slugs:
- TypeScript →
ts, JavaScript →js, Python →py, Rust →rust, Go →go - React →
react, Vue →vue, Svelte →svelte, Next.js →nextjs - Node.js →
nodejs, Deno →deno, Bun →bun - PostgreSQL →
postgres, Redis →redis, MongoDB →mongodb - Docker →
docker, Kubernetes →kubernetes, AWS →aws - Tailwind →
tailwind, Prisma →prisma, GraphQL →graphql
Row 3 — Social Proof (only if GitHub repo):
VISUAL DIVIDERS
Use capsule-render thin separators between major sections:
<img src="https://capsule-render.vercel.app/api?type=rect&color=gradient&customColorList={SAME_PALETTE_AS_HERO}&height=1" width="100%" />
This gives visual rhythm — like sections on a landing page.
HOOK PARAGRAPH
2-3 sentences MAX. Not a feature list. Answer: "Why should I care about this project?"
Write in a confident, concise voice. Lead with the problem, follow with the solution. Example:
Building APIs shouldn't require 500 lines of boilerplate. ProjectName gives you type-safe endpoints, auto-generated docs, and zero-config deployment — in under 50 lines of code.
Derive from: package description, README intro (if exists), repo topics, and code analysis.
FEATURES / HIGHLIGHTS
Use a visual grid, NOT a bullet list:
<table>
<tr>
<td width="50%" valign="top">
### ⚡ Lightning Fast
Built on Rust's async runtime, handles 100K+ requests/sec out of the box.
</td>
<td width="50%" valign="top">
### 🔒 Type-Safe
End-to-end TypeScript types — from database to frontend.
</td>
</tr>
<tr>
<td width="50%" valign="top">
### 📦 Zero Config
Sensible defaults. Override only what you need.
</td>
<td width="50%" valign="top">
### 🧩 Plugin System
Extend with community plugins or build your own.
</td>
</tr>
</table>
Derive features from actual code analysis — exports, README claims, package keywords. Do NOT invent features.
QUICK START — Tabbed Installation
Detect available package managers and generate tabs:
<details open>
<summary><strong>npm</strong></summary>
```bash
npm install package-name
yarn add package-name
pnpm add package-name
For non-package projects (e.g., apps), generate:
```bash
git clone https://github.com/{owner}/{repo}.git
cd {repo}
{detected_install_command}
{detected_start_command}
### ARCHITECTURE DIAGRAM
Auto-generate a Mermaid diagram from directory structure scan. Only include if the project has sufficient complexity (>3 source directories or clear multi-service architecture).
```markdown
```mermaid
graph LR
A[Client] --> B[API Gateway]
B --> C[Auth Service]
B --> D[Core Service]
D --> E[(Database)]
D --> F[(Cache)]
Use emoji in node labels for visual richness. Map to detected components:
- Frontend → `📱`
- API/Router → `🔀`
- Auth → `🔐`
- Database → `🗄️`
- Cache → `🔴`
- Queue → `📨`
- Storage → `📁`
- External API → `🌐`
### DIRECTORY TREE
Use decorated tree with emoji and annotations:
```markdown
📦 project-root ├── 📂 src/ │ ├── 📂 api/ # REST endpoints │ ├── 📂 core/ # Business logic │ ├── 📂 db/ # Database layer │ └── 📂 utils/ # Shared utilities ├── 📂 tests/ # Test suites ├── 📄 Dockerfile └── 📄 docker-compose.yml

CONTRIBUTING SECTION
If --contributing flag or user requests it, generate a separate CONTRIBUTING.md with:
- Getting Started — clone, install, run dev server (detected from scripts)
- Branch Strategy — detected from git branches
- Code Style — detected linters and formatters
- Testing — detected test framework and how to run tests
- PR Process — if
.github/PULL_REQUEST_TEMPLATE.mdexists, reference it - Code of Conduct — link if exists
In the README, add a contributing section that links to it:
## Contributing
We welcome contributions! Please see our [Contributing Guide](CONTRIBUTING.md) for details.

Monorepo Mode
When a monorepo is detected (workspace configs like pnpm-workspace.yaml, lerna.json,
Cargo workspaces, Go workspaces, or Nx/Turborepo configs), the skill generates a
multi-layer README structure.
Detection Signals
pnpm-workspace.yaml/lerna.json/nx.json/turbo.json→ JS/TS monorepoCargo.tomlwith[workspace]→ Rust monorepogo.work→ Go workspace- Multiple
package.jsonfiles inpackages/orapps/directories
What Gets Generated
1. Root README — the "landing page" for the entire monorepo:
[Hero — monorepo name + tagline]
[Badges — overall CI, license, contributor count]
[Hook paragraph — what this monorepo contains and why]
## Packages
| Package | Description | Version | Status |
|---------|-------------|---------|--------|

| [@scope/cli](./packages/cli) | CLI interface | v1.3.0 | [](link) |
| [@scope/ui](./apps/web) | Web dashboard | v0.9.0 | [](link) |
[Architecture diagram showing package relationships]
[Health scorecard — aggregate across all packages]
[Contributing + License + Footer]
Auto-generate the package table from workspace config — scan each package's
package.json/Cargo.toml for name, version, and description.
2. Per-Package READMEs (optional — ask in interview):
Each package gets a focused, smaller README:
- Scoped hero (simpler — just package name + description, no capsule render)
- Package-specific badges (its own version, its own build status)
- Install instructions specific to that package
- API reference if it's a library
- Link back to root README
Per-package READMEs use --style minimal by default to avoid visual overload.
Mermaid Package Dependency Graph
For the root README, generate a dependency graph showing how packages relate:
graph TD
A["@scope/core"] --> B["@scope/cli"]
A --> C["@scope/ui"]
A --> D["@scope/api"]
E["@scope/shared"] --> A
E --> C
Derive from dependency fields in each package's manifest.
Update Mode (--update) — Smart Merge vs Regenerate
The skill has two update strategies. It auto-detects which one to use.
Strategy A: Merge (Default)
Used when the codebase evolved incrementally — new features, dependency updates, version bumps, added files. The README structure is still valid.
How to detect (all must be true):
- Existing README has
<!-- readme-gen:markers from a previous generation - Directory structure is broadly the same (no renames of top-level dirs)
- Primary language and framework haven't changed
- No workspace config changes (didn't switch from single-package to monorepo)
Merge behavior:
- Read the existing README fully
- Identify generated sections by
<!-- readme-gen:start:{section} -->/<!-- readme-gen:end:{section} -->markers - Re-scan the repo and regenerate ONLY the marked sections:
- Badges (versions, build status, coverage)
- Tech stack icons
- Architecture diagram
- Health scorecard
- Directory tree
- Preserve ALL user-written sections untouched
- Add any NEW sections that the scan now justifies (e.g., project gained Docker support → add Deployment section)
- Update
.readme-gen.jsontimestamp
Strategy B: Regenerate
Used when the codebase underwent a major refactor — language migration, monorepo conversion, framework swap, directory restructure.
How to detect (any one triggers regenerate):
- Primary language changed (e.g., JavaScript → TypeScript, Python → Rust)
- Framework changed (e.g., Express → Fastify, CRA → Next.js)
- Project structure fundamentally changed (flat → monorepo, or vice versa)
- Top-level directories renamed or reorganized (>50% of src dirs changed)
- No
<!-- readme-gen:markers found (README was manually written or from another tool)
Regenerate behavior:
- Back up existing README to
README.old.md - Run the full generation pipeline from scratch (Phase 1 → 2 → 3 → 4)
- In the interactive interview (Phase 2.5), show the user what changed:
"Detected major changes: migrated from JavaScript to TypeScript, added monorepo structure. I'll regenerate the README from scratch. Your previous README is backed up at
README.old.md." - Write new README with full markers
Section Markers
All generated sections are wrapped in HTML comments for future updates:
<!-- readme-gen:start:badges -->
<!-- readme-gen:end:badges -->
<!-- readme-gen:start:tech-stack -->
<p align="center"><img src="https://skillicons.dev/..." /></p>
<!-- readme-gen:end:tech-stack -->
<!-- readme-gen:start:architecture -->
```mermaid
graph LR ...
| Category | Status | Score | ...
📦 project-root
...
...
Sections WITHOUT markers are considered user-written and are NEVER modified during merge.

## Critical Rules
1. **NEVER invent features** — only describe what the code actually does
2. **NEVER include empty sections** — if there's nothing to say, skip it
3. **NEVER dump 20+ badges** — curate. Only meaningful status indicators
4. **ALWAYS verify URLs** — test that badge URLs use correct owner/repo/workflow names
5. **ALWAYS use the detected license** — don't guess
6. **ALWAYS preserve existing user content** in update mode
7. **ALWAYS center the hero block** — use `<div align="center">`
8. **ALWAYS match capsule-render palette** between hero and footer
9. **The tagline is the most important line** — spend time on it. It must be compelling, not generic
10. **Write for humans, not search engines** — the hook paragraph should read like a great tweet, not a feature list

## Example Output Structure
For a TypeScript + React + PostgreSQL web app called "Velox":
[Capsule Render Waving Hero — vibrant gradient, "Velox", tagline]

## Automated Freshness Hooks
This skill is backed by two workspace hooks that keep READMEs from going stale:
### Hook 1: Push Counter (Activity-Based)
A `PostToolUse` hook on `Bash` fires after every command. A script at
`~/.craft-agent/workspaces/my-workspace/scripts/readme-push-counter.sh`
detects `git push` commands and increments a per-repo counter.
**After 5 pushes** (configurable via `README_PUSH_THRESHOLD` env var), the agent
receives a nudge message:
> README Update Reminder: You've pushed 5 times to "my-project" since the last
> README check. Consider running `/readme --update` to keep it fresh.
**When you see this nudge:**
1. Mention the reminder to the user naturally (don't be annoying — one mention is enough)
2. If the user says yes, run `/readme --update` on the repo
3. If the user ignores it, don't bring it up again until the next threshold
The counter resets after each nudge, so the next reminder fires after another 5 pushes.
### Hook 2: Weekly Release Check (Scheduled)
A `SchedulerTick` cron hook runs **every Monday at 10:00 AM IST**. It creates a new
session labeled `Scheduled` + `readme-check` that scans for:
- New git tags or releases since the last README update
- Tech stack changes (added/removed dependencies)
- New directories or major structural changes
- CI/CD config changes
If changes are detected, the session suggests running `/readme --update`.
### Customizing the Hooks
Users can adjust these in `~/.craft-agent/workspaces/my-workspace/hooks.json`:
- **Push threshold**: Set `README_PUSH_THRESHOLD` environment variable (default: 5)
- **Cron schedule**: Edit the cron expression (default: `0 10 * * 1` = Monday 10 AM)
- **Timezone**: Edit the timezone (default: `Asia/Kolkata`)
- **Disable**: Remove the relevant hook entry from hooks.json
