# Agent Skills
AI agent skills are reusable instruction sets that extend your assistant with domain-specific expertise, loaded on demand so they don't bloat your context. This repository covers marketing and engineering skills authored by [@samber](https://github.com/samber).
For Golang-related skills, please visit [cc-skills-golang](https://github.com/samber/cc-skills-golang).

> Bootstrapped with Claude. **Edited, tested, reviewed and reworked by a human**.
>
> **No AI slop here.** AI-made skills are useless.

## 🧩 Skills
These skills are designed as **atomic units, cross-referencing units**. A skill may reference conventions defined in another. Installing only a subset will give you a partial and potentially inconsistent view of the guidelines. For best results, install all general-purpose skills together.
Each skill lives in `skills/<name>/` with a `SKILL.md` entry point. The `SKILL.md` is kept small with internal references to advanced markdown files, so only the relevant content is loaded into context.
- **Description (tok)**: weight of the `description` field from YAML frontmatter, always loaded into Claude's context for skill triggering
- **SKILL.md (tok)**: weight of the full `SKILL.md` file loaded when the skill triggers
- **Directory (tok)**: weight of all files in the skill directory (SKILL.md + referenced markdown files)
```

## 📖 Skills description
### Engineering
#### `chrome-extension`
Chrome Extension development with Manifest V3. Covers architecture, messaging, CSP, storage, permissions, content scripts, service workers, and Chrome Web Store publishing.
#### `conventional-git`
Conventional Commits v1.0.0 for branch naming, worktree naming, and commit messages. Keeps git history parseable for auto-changelogs, SemVer bumps, and issue closing.
#### `crxjs`
CRXJS Chrome extension development with Vite. True HMR for popup/options/content scripts/side panels, `defineManifest` for type-safe manifests, dynamic content script imports.
#### `frontend-design-deslop`
Strategy-first UI design for web frontends, apps, dashboards, and landing pages. Escapes AI-generated generic aesthetics (Inter + indigo + rounded cards) by committing to brand adjectives, then deriving a typography and color system, component state matrices, layout rhythm, motion, iconography, and dark mode. Produces a `DESIGN.md` design token contract.
#### `promql-cli`
CLI for querying Prometheus and PromQL-compatible engines (Thanos, Cortex, VictoriaMetrics, Mimir). Instant/range queries, metric discovery, table/csv/json/graph output.
### Marketing & Content
#### `copywriting-cta`
End-of-article CTA design. Interviews for objective, audience, and context, then produces copy + visual form + mechanism + A/B test plan + accessibility check.
#### `copywriting-hooks`
Opening hooks for long-form articles (blog posts, Substack, LinkedIn long-form, newsletters). Proposes 3-4 hooks with distinct psychological levers: curiosity, contrarian, scene, promise, authority.
#### `copywriting-prose-creator`
Codifies prose mechanics (lexicon, syntax, rhythm, structure) into a PROSE.md style guide. Three modes: BUILD fresh, ADAPT to new channel, AUDIT a corpus. For content factories, ghostwriting teams, house style guides.
#### `copywriting-tone-of-voice-creator`
Builds brand tone of voice guides (TONE.md) with voice attributes, modulation matrix, lexicon, and channel rules. Create from scratch or adapt to a new channel. For B2B, B2C, NGO, public sector, personal brands.
#### `humaniseur-fr`
Removes AI-writing patterns from French text. Detects and fixes 27 patterns: AI vocabulary, anglicisms, formulaic openings, em dash abuse, sycophantic tone, typographic tells.
#### `humanizer-en-asd-ste100`
Rewrites English into ASD-STE100 Simplified Technical English (Issue 9) and de-slops technical documentation — decorative emojis, conversation leftovers, Markdown residue, mixed quote styles. Enforces the 53 rules across 9 sections — approved word meanings, technical noun/verb categories, sentence-length limits, banned verb tenses, passive-voice restrictions — for maintenance manuals, equipment procedures, and any technical text read by non-native speakers or machine translation.
#### `linkedin-ghostwriting`
B2B LinkedIn ghostwriting via strategic interview, hook engineering, and post body. Turns founder stories and results into conversion-focused posts.
#### `press-release-writer`
Professional press releases for any occasion and region. Product launches, funding, partnerships, crisis, M&A, events. Region-specific conventions (Europe, Americas, Asia, etc.).
#### `site-launch-checklist`
Pre-launch checklist for shipping a website. Analytics (GA4, PostHog, GSC), legal, security headers, SEO/GEO, copywriting pass, OpenGraph, favicons, Lighthouse, accessibility. Opinionated for Cloudflare + Vercel.
### Developer Relations

#### `influence-and-negotiation`
Negotiation and influence toolkit for any interaction requiring agreement. B2B sales, salary, collective bargaining, hard 1:1s, recruitment, cross-cultural deals. Preparation, live coaching, and diplomatic drafting.
#### `training-report`
Generates structured training reports from session data. Tracks progress, skills acquired, and outcomes.
### Meta
#### `skill-progressive-disclosure-design`
Design patterns for skill progressive disclosure. Structures skill content for lazy loading so only relevant sections enter context.
#### `snyk-agent-scan-compliance`
Compliance expert for snyk-agent-scan. Validates security scan configurations and ensures compliance with organizational policies.
## 🎯 Tuning Skill Triggers
If a skill triggers too often or not often enough, please [open an issue](https://github.com/samber/cc-skills/issues) suggesting a description change. The `description` field in SKILL.md frontmatter is the primary triggering mechanism: small wording adjustments can significantly improve trigger accuracy. Some `SKILL.md` might have a `When to use` section which is another level of exclusion. Finally, `SKILL.md` is an entrypoint for lazy loading references with deep knowledge located in `references/`.
## 🔄 Overlap
If your team has its own conventions, create a company skill and declare the override explicitly near the top of its body: `This skill supersedes samber/cc-skills@git-convention skill for [company] projects.`
## ✍️ Contribute
- **100 tokens per skill description** - what? when to use this skill?
- **1.000–2.500 tokens per SKILL.md** — keep the main file focused on essentials
- **Use secondary markdown files for depth** — reference them from SKILL.md with relative links (e.g., `[Logging](./logging.md)`). Claude reads these on demand when the topic is relevant, so they don't count against the context budget until needed
- **Up to 10.000 tokens** for full skill and secondary files
- **2–4 skills loaded simultaneously** in a typical session — design skills to coexist
- **Stay below ~10k tokens of total loaded SKILL.md** anytime to avoid degrading response quality
For more guidelines, please check `CLAUDE.md`.
