Veille « droit des affaires » — agent quotidien

A headless Claude Code agent that, every morning, reads the latest Journal Officiel via the Légifrance API, summarises the items relevant to French business law, and emails you the digest. Runs free on GitHub Actions.

How it works

GitHub Actions (cron)
  └─ claude -p  (headless agent, reads CLAUDE.md + agent_prompt.md)
       └─ legifrance.py  → Légifrance JORF API (official texts, open data)
       └─ writes digest.html + subject.txt
  └─ send_email.py  → Resend  → your inbox

The agent step and the email step are separate on purpose: even if the agent fails, you still get an email (with a fallback message + a link to the logs).

Setup (about 15 minutes)

1. Légifrance / PISTE credentials (free)

1. Create an account at https://piste.gouv.fr/registration
2. Accept the Légifrance CGU: API → Consentement CGU API.
3. Create an application, then edit it and tick the Légifrance API.
4. Copy the Client ID and Client Secret (OAuth identifiers).

2. Resend (email)

1. Create an account at https://resend.com and get an API key.
2. To send from your own address, verify a domain (DNS records). For a first test you can set EMAIL_FROM to onboarding@resend.dev — but Resend will then only deliver to the email address of your own Resend account.

3. Anthropic API key

Get one from https://console.anthropic.com — this is what authenticates the headless Claude Code run. (Cost is small: a daily digest is well under a cent to a few cents per run.)

4. Push to GitHub and add secrets

Create a repo, push these files, then go to Settings → Secrets and variables → Actions → New repository secret and add:

Secret	Value
ANTHROPIC_API_KEY	your Anthropic key
PISTE_CLIENT_ID	from step 1
PISTE_CLIENT_SECRET	from step 1
RESEND_API_KEY	from step 2
EMAIL_TO	your inbox
EMAIL_FROM	e.g. Veille Juridique <veille@your-domain.fr>

5. Test it

In the repo's Actions tab, open the workflow and click Run workflow (workflow_dispatch). Check the logs and your inbox. Once happy, the daily cron takes over.

Local testing

pip install -r requirements.txt
cp .env.example .env   # fill it in
set -a; . ./.env; set +a

python legifrance.py list           # see today's JO texts as JSON
claude -p "$(cat agent_prompt.md)" --allowedTools "Bash,Read,Write"
python send_email.py

Tuning

• What counts as business law lives in CLAUDE.md — edit the scope there.
• Schedule: change the cron line in .github/workflows/daily-digest.yml (it's in UTC). Note GitHub may delay scheduled runs under load.
• Sources: this uses the official JORF only. To add commentary/context, you can give the agent web access — but keep official texts as the backbone and have it paraphrase any press source rather than reproduce it.

If a Légifrance call errors

The OAuth token call and /consult/lastNJo are stable. The script parses the jorfCont / jorf responses generically and tries several payload shapes, so it tolerates minor schema changes. If you still get a 400/404, check the current Swagger for the Légifrance API on PISTE and adjust the payloads in legifrance.py (clearly marked in cmd_list / cmd_text).
