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 | $0.00017 | $0.00704 |
| Opus 5.5 | $0.00007 | $0.00282 |
| Sonnet 5.5 | $0.00003 | $0.00141 |
| Haiku 4.5 | $0.00002 | $0.00070 |
Grade A, and why
dev-backend 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 1mo 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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/dev-backend — Génère le code serveur d'UNE US
⚠️ Commande interne v7.0.0 — invoquée par
/dev-runSTEP 6.a (batch 1 US). Utilisateur final : préférer/sdd-fullou/dev-run(gèrent pré-conditions, idempotence, état).
Invoque l'agent dev-backend pour matérialiser l'US
workspace/us/{n}-{m}-{Name}.md en code serveur (services, endpoints,
DTOs, entities, mappers, Program.cs, middleware). L'agent planifie
inline les fichiers à produire à partir de l'US + du stack actif.
Si l'US n'a aucune contrepartie backend (US frontend pure), l'agent
exit silencieusement avec une ligne skipped (frontend-only US).
1 invocation = 1 US = 1 build backend. Pour traiter plusieurs US,
lancer la commande plusieurs fois ou utiliser /dev-run {n}.
Usage : /dev-backend {n}-{m} — où {n}-{m} cible une US existante
(ex. /dev-backend 1-3).
STEP 1 — Valider l'argument
Argument obligatoire : {n}-{m} (deux entiers ≥ 1 séparés par un
tiret).
Si absent → demander :
Quelle est l'US à matérialiser côté backend ? (format : {n}-{m}, ex. 1-3)
Si format invalide →
ERROR: /dev-backend — argument invalide
CAUSE: [INVALID_ARG] "{argument}" ne respecte pas le format {n}-{m}
FIX: relancer /dev-backend {n}-{m} (ex. /dev-backend 1-3)
STEP 2 — Invoquer l'agent dev-backend
Lancer l'agent dev-backend (défini dans .claude/agents/dev-backend.md)
avec l'argument {n}-{m}. L'agent gère :
- la lecture sélective de l'US, du mockup HTML éventuel (passif), du stack actif
- le plan inline des fichiers serveur (ou exit silencieux si US frontend-only)
- la génération de code conforme au mapping du stack
- le build loop (max 3 itérations)
- la confirmation 1 ligne
Attendre la fin de l'agent. Relayer sa sortie telle quelle.
STEP 3 — Confirmation finale
Si l'agent réussit avec génération, ajouter UNE SEULE ligne :
Prochaine étape : si l'US a une partie frontend, lancer /dev-frontend {n}-{m}.
Si l'agent réussit en skipped ou échoue, ne rien ajouter.
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.

dev-backend is a command published in the GitHub repository zekiriabd/SDD-Pro (196 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 17 tokens to every session and 704 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
