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 | $0.00114 | $0.01439 |
| Opus 5 | $0.00057 | $0.00720 |
| Sonnet 5 | $0.00023 | $0.00288 |
| Haiku 4.5 | $0.00011 | $0.00144 |
Grade A, and why
sdd-reverse-synth 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 3d 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 — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/sdd-reverse-synth {LegacyProject} [--doc-level essentiel|complet|detaille] [--only c4,erd,soul] [--json]
Rôle
Produire la vue système que l'escalier 3a→3b→3c ne produit pas : diagrammes
C4, ERD complet et soul.md (synthèse exécutive). C'est un nouvel
étage au-dessus de 3c : un consommateur en lecture seule des artefacts
déterministes déjà présents, qui ne touche ni à l'escalier, ni au contrat
FEAT.
Pare-feu (non-cassant) : tous les artefacts sont écrits sous
workspace/old/{P}/.sys/synthesis/— jamais sousworkspace/feats/./sdd-fullne voit donc jamais un C4/ERD comme une FEAT à coder.

Pré-conditions
workspace/old/{P}/.sys/inventory.jsonprésent etschemaVersion == 1(sinon → STOP[REVERSE_NO_SOURCE]/[REVERSE_INVENTORY_SCHEMA_STALE]).- Recommandé :
/sdd-reverse-auditexécuté avant (produitdeps-graph.json→ C4 plus riche, etdb-schema.merged.json→ ERD enrichi). Dégradation gracieuse si absents : le C4 se limite au contexte, l'ERD à la base.
Actions (no-spawn — script déterministe)
Invoque le script déterministe, aucun agent :
python .sdd/python/sdd_reverse_scripts/reverse_synth.py --project workspace/old/{LegacyProject} [--doc-level ...] [--only ...] [--json]
Le script :
- Charge
inventory.json(requis),deps-graph.jsonetdb-schema.merged.json(oudb-schema.json) si présents. - Nettoie les sorties gérées de chaque catégorie régénérée (idempotence :
repasser à un
--doc-levelinférieur n'y laisse pas d'artefact périmé). - Rend, sous
.sys/synthesis/, selon le doc-level :c4-context.md,c4-containers.md,c4-components.md,erd-complete.md,soul.md. - Écrit
manifest.json(enregistrement d'observabilité dérivé — quels artefacts, depuis quelles sources, répartition de confiance). - Émet la ligne chat finale :
[REVERSE] Synthèse ({doc-level}) : {fichiers} [confiance high=.. medium=.. low=..]. (100%)
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.

sdd-reverse-synth is a command published in the GitHub repository zekiriabd/SDD-Pro (191 stars, last pushed 4d ago), licensed Apache-2.0. It adds 114 tokens to every session and 1,439 once invoked, about $0.0006 per session on Opus 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 2026-09-03.
