Paperasse is a collection of skills that help AI agents handle French business bureaucracy, including accounting, taxation, invoicing, auditing, notarial law, and condominium management. It is intended for users of agents such as Claude Code, Codex, Cursor, and similar tools, and includes connectors for Qonto transactions and Stripe payments.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00302 | $0.05015 |
| Opus 5 | $0.00151 | $0.02508 |
| Sonnet 5 | $0.00060 | $0.01003 |
| Haiku 4.5 | $0.00030 | $0.00502 |
Grade A, and why
fiscaliste scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 312 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Règle Absolue
Ne jamais donner de chiffre sans expliquer la séquence de calcul.
Face à une question fiscale :
- Si l'utilisateur fournit des chiffres → calculer étape par étape en montrant chaque intermédiaire (revenu brut → RNI → quotient → impôt brut → décote → impôt net).
- Si l'utilisateur ne fournit pas de chiffres → expliquer la logique et identifier quelles valeurs il faut aller chercher.
Ne jamais inventer un barème. Utiliser exclusivement les valeurs inlinées ci-dessous pour les revenus 2025 (déclaration 2026). Pour toute autre année, renvoyer à impots.gouv.fr.

Quotient familial
- Plafond du gain par demi-part supplémentaire : 1 807 € (enfant à charge)
- Parent isolé (case T) : plafond 4 273 € pour la première part liée à l'enfant
- Veuf avec enfant à charge : plafond 4 273 €
Décote (plancher à 0)
- Célibataire : si impôt brut < 1 982 € → décote = 897 − 0,4525 × impôt brut
- Couple : si impôt brut < 3 277 € → décote = 1 483 − 0,4525 × impôt brut
Abattements
| Revenu | Case 2042 | Abattement |
|---|---|---|
| Salaires | 1AJ/1BJ | 10 % (min 509 €, max 14 555 €) ou frais réels |
| Pensions / retraites | 1AS/1BS | 10 % (min 450 €, max 4 446 €) par foyer |
| Chômage (ARE) | 1AP/1BP | 10 % — l'ARE est un revenu de remplacement imposé selon les règles des traitements et salaires (BOI-RSA-BASE-30-50-20) ; l'abattement de 10 % s'applique sur le total salaires + ARE. Se déclare en 1AP/1BP (pas en 1AJ), mais bénéficie bien de l'abattement. |

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
