## Method

- [How I use Claude](https://hl-consulting.tech/knowledge-hub/en/how-to/): CLAUDE.md + extensions, Compound Engineering, brand DNA file, Claude Chat vs Claude Code, prompt to copy.

## Guides (evergreen)

- [All guides](https://hl-consulting.tech/knowledge-hub/en/guides/): a series of clear guides to understand AI and make decisions — for merchants and business owners, readable at any level.
- [What is AI, and what's an "LLM"?](https://hl-consulting.tech/knowledge-hub/en/guides/cest-quoi-ia-llm.html): generative AI and LLMs without the jargon — the difference between AI/ML/DL/LLM, next-token prediction, the big players (OpenAI/ChatGPT, Anthropic/Claude, Google/Gemini, Meta/Llama, Mistral, DeepSeek, xAI/Grok, Microsoft/Copilot, Perplexity), and what an LLM can NOT do (hallucinations; not connected to the internet or your data by default).
- [What is Claude, and why did I build everything on it?](https://hl-consulting.tech/knowledge-hub/en/guides/cest-quoi-claude.html): Anthropic's AI assistant — the Opus/Sonnet/Haiku size tiers, why it's in the top tier (Karpathy joining Anthropic in May 2026), and everything Hugo runs on it (Cobra, Haute Fidélité, daily monitoring, this site).
- [Fable, Mythos, Glasswing: why Anthropic released two versions of the same model](https://hl-consulting.tech/knowledge-hub/en/guides/fable-mythos-glasswing.html): on June 9, 2026, Anthropic launched Claude Fable 5 — the first model in a "Mythos" class above Opus ($10/$50 per MTok, free for subscribers until June 22). The unguarded version, Mythos 5, is restricted to vetted cyberdefenders through Project Glasswing.
- [What is a "loop"? Recurring agent tasks](https://hl-consulting.tech/knowledge-hub/en/guides/cest-quoi-une-loop.html): an agent re-running the same task at a regular interval (monitor, check, alert) — Claude Code's /loop (auto-expiry after 3 days), how it differs from a durable scheduled task, and retail use cases.
- [Why AI is genuinely changing the way we work](https://hl-consulting.tech/knowledge-hub/en/guides/pourquoi-lia-change-le-travail.html): AI as a general-purpose technology ("AI is the new electricity", Andrew Ng); the signals that this isn't hype; the shift from "doing → overseeing and verifying"; what it doesn't change (judgment).
- [Chat, Cowork, or Code: which one to use (and the "terminal")](https://hl-consulting.tech/knowledge-hub/en/guides/chat-cowork-code-terminal.html): the three ways to use Claude (chat / delegate / act), the terminal demystified, installing Claude Code in one command, and why you don't need a powerful machine (all the computing happens on Anthropic's servers).
- [What is GitHub, and why is it free and magical](https://hl-consulting.tech/knowledge-hub/en/guides/cest-quoi-github.html): GitHub for non-devs — full history and rollback, free, industry standard, and automatic deployment once connected (Claude Code handles versioning).
- [What's an "MCP", and how to connect Claude to your tools](https://hl-consulting.tech/knowledge-hub/en/guides/cest-quoi-mcp-connecter-claude.html): the 4 levels of connection (copy-paste → browser → API → MCP) and MCP (Model Context Protocol, Anthropic's open standard, "USB plug") to link Claude to Shopify, Drive, Gmail.
- [What's an "AI agent"?](https://hl-consulting.tech/knowledge-hub/en/guides/cest-quoi-un-agent-ia.html): assistant (responds) vs agent (acts in a loop toward a goal); what it's for; the essential guardrails (goal, budget, frequency, success criteria); start small.
- [Writing a good CLAUDE.md (the most valuable file you'll ever make)](https://hl-consulting.tech/knowledge-hub/en/guides/ecrire-un-bon-claude-md.html): the context file (tone & format, conventions, off-limits, pitfalls→rules); short and concrete; it grows with every corrected mistake.
- [The 4 principles I apply with AI (Karpathy style)](https://hl-consulting.tech/knowledge-hub/en/guides/principes-facon-karpathy.html): who Andrej Karpathy is (joined Anthropic in May 2026) and 4 reflexes — think before you act, simplicity first, surgical edits, goal-driven execution.
- [Compound Engineering: your method improves itself](https://hl-consulting.tech/knowledge-hub/en/guides/compound-engineering.html): turning every lesson into a reusable rule (term popularized by Kieran Klaassen & Dan Shipper, Every); the compound interest effect on how you work.
- [AI in practice, for a merchant or an SME](https://hl-consulting.tech/knowledge-hub/en/guides/lia-pour-un-commercant.html): the use cases that pay off (product descriptions, SEO, cross-referencing sales, emails, market monitoring), doable without a tech team, where to start, and the traps.
- [Is my data safe with AI?](https://hl-consulting.tech/knowledge-hub/en/guides/mes-donnees-sont-elles-en-securite.html): where data goes (cloud, encrypted in transit), training (consumer vs pro/API offerings that don't train by default — check the clause), data sovereignty (Europe, Mistral, self-hosted model), and 4 reflexes (right plan, disable training, no unnecessary secrets, sovereign for sensitive data).
- [How to talk to AI properly: writing a good prompt](https://hl-consulting.tech/knowledge-hub/en/guides/ecrire-un-bon-prompt.html): a prompt = the instruction; recipe for a good prompt (context, task, format, constraints + one example); reflexes (give an example, iterate, ask AI to ask questions, role, break it down); no "magic phrase" — clarity wins.
- [Being visible in AI: GEO explained](https://hl-consulting.tech/knowledge-hub/en/guides/etre-visible-dans-lia-geo.html): SEO (being found on Google) vs GEO (being cited in an AI's answer: ChatGPT, Perplexity, Claude, AI Overviews); why it matters; how to get cited (Q&A structure, citable statements, structured data schema.org, clear entity, llms.txt); emerging field, this site as an example.
- [How much does AI cost: subscriptions, API, and keeping the bill under control](https://hl-consulting.tech/knowledge-hub/en/guides/combien-coute-lia.html): everything is counted in tokens; 4 pricing models (free, subscription ~€20/month, pay-per-use API, enterprise per seat); subscription for chatting / API for automating; controlling costs (spending caps, right model, scoped agents).

## Build in public — case studies

- [Do you still need to buy an ERP when AI lets you build your own?](https://hl-consulting.tech/knowledge-hub/en/guides/faut-il-encore-acheter-un-erp.html): HF-OS dossier — a press ERP built from scratch in 5 days / 96 PRs with Claude Code, plus Odoo extended at Cobra; CRM, ad sales, invoicing, dunning; the real build-vs-buy question.
- [A site + an AI bot in a weekend?](https://hl-consulting.tech/knowledge-hub/en/guides/site-bot-ia-en-un-week-end.html): pillar guide — how a non-developer ships a static site and a serverless AI monitoring bot in one weekend with Claude Code (need, minimal stack, separation of concerns, visual loop, guardrails).
- [Case study — Knowledge Hub](https://hl-consulting.tech/knowledge-hub/en/guides/etude-de-cas-knowledge-hub.html): from idea to production of a complete static site (vanilla HTML/CSS/JS, GitHub Pages, CSS token dark mode, GEO layer). Decisions, struggles (anti-FOUC, iOS cache), real time, zero token cost.
- [Case study — AI monitoring bot](https://hl-consulting.tech/knowledge-hub/en/guides/etude-de-cas-veille-ia.html): a serverless agent (X/Twitter + RSS → Claude API → Telegram + feed.json on the site), orchestrated by GitHub Actions. 2-repo architecture, cross-repo bridge, CI struggles, real cost ~a few cents/day.
- [Case study — Supplier invoice agent](https://hl-consulting.tech/knowledge-hub/en/guides/etude-de-cas-agent-facturation.html): an autonomous agent that reads email (Microsoft Graph), extracts invoices (OCR + Claude API), links them to the Odoo purchase order (guaranteed 3-way match, price check), and pushes them for approval in Teams. Hosted on a Scaleway instance, 15-min cron. Human drift quantified (~€2M off-chain) and a workflow that can no longer drift. What the agent doesn't do (bank reconciliation) said honestly.
- [Making-of](https://hl-consulting.tech/knowledge-hub/en/guides/making-of.html): the story, from a dinner with friends to a "beautiful thing shipped in 2 days", side by side with Claude Code.

## Journal (52 entries)

- [The invoice agent goes to production: autonomous on Scaleway](https://hl-consulting.tech/knowledge-hub/en/journal/agent-factures-prod-scaleway.html): Cobra's supplier invoice processing agent now runs on its own on a Scaleway instance: it reads email every 15 min via Microsoft Graph, extracts each invoice (OCR + Claude API), links it to its Odoo purchase order (guaranteed 3-way match) and pushes it for approval in Teams. ~9-10 hrs/week saved — and above all a workflow that can no longer drift (before: ~€2M of invoices entered off-chain, €600k of lingering unpaid).
- [Product AI agent — from one-shot script to dashboard CDC](https://hl-consulting.tech/knowledge-hub/en/journal/agent-produit-ia-cdc-dashboard.html): We created the 36 Davis variants by hand, in a Python script. Rather than starting over for every new brand, we formalized the method: a conversational AI agent on the Cobra dashboard that reads any source file and creates or updates Odoo products with no technical step.
- [Davis catalog → Odoo: price-list extraction + creation brief (Krypton & Ariane)](https://hl-consulting.tech/knowledge-hub/en/journal/davis-odoo-krypton-ariane.html): Preparing the integration of a new speaker brand (Davis, Krypton + Ariane ranges) into Odoo 18: a clean extraction of the supplier price list into 11 models / 36 variants, and a Claude Code brief — read-only first, create only after a green light. Nothing created in the database yet — deliberately.
- [HF-OS: a Next.js 16 + Payload 3 foundation deployed, admin login via Google](https://hl-consulting.tech/knowledge-hub/en/journal/hf-os-socle-deploiement.html): Bootstrapping then shipping the HF-OS technical foundation (Next.js 16 + Payload 3, Scaleway PostgreSQL, Render hosting), with admin login via Google SSO restricted to an allow-list.

- [Re-linking a Shopify product to Odoo: a LINK/RELINK wizard in cobra_shopify](https://hl-consulting.tech/knowledge-hub/en/journal/shopify-link-relink-wizard.html): Odoo↔Shopify links broke when a product was recreated with variants (orphaned history). After a script rescue (Focal Bathys MG), we made it a feature: a LINK/RELINK wizard in cobra_shopify — SKU matching, atomic swap, no script.
- [Odoo → Shopify: product archiving and re-listing finally in sync](https://hl-consulting.tech/knowledge-hub/en/journal/shopify-archivage-produits-eol.html): The connector reflected neither archiving nor re-listing of a product. 3 bugs fixed in cobra_shopify + a cleanup script (~590 stale records purged, 2 still-purchasable products made unavailable).
