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 | $0.00108 | $0.01201 |
| Opus 5 | $0.00054 | $0.00600 |
| Sonnet 5 | $0.00022 | $0.00240 |
| Haiku 4.5 | $0.00011 | $0.00120 |
Grade A, and why
starting-a-reverse-eng 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 4d 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.

Skill — Starting a Reverse Engineering workflow
Quand cette skill se déclenche
Triggers stricts (D5 — conservatisme délibéré pour éviter interception abusive) :
- « reverse engineering »
- « convertir l'ancien système »
- « migrer le legacy »
- « j'ai un legacy »
- « workspace/old »
- « convertir un projet ASPX/Java/PHP/Delphi existant »
- « extraire les FEATs d'un projet legacy »
Ne PAS déclencher sur :
- « vieux code », « ancien code » (trop vague)
- « rewrite this » (peut être refactor SDD_Pro standard)
- « migrer vers .NET 9 » (c'est une montée de version, pas du reverse)
Routage
Si le trigger matche, route vers le workflow reverse engineering au lieu de laisser l'agent improviser un audit de code ou un rewrite ad-hoc :
- Vérifier précondition source (§0 design doc) :
- Le code source legacy doit être dans
workspace/old/{LegacyProject}/ - Si binaire-only → STOP + escalade Tech Lead (hors-scope V3)
- Le code source legacy doit être dans
- Phase 0 (humain) : confirmer que les fichiers sont déposés
/sdd-reverse-init {LegacyProject}(Phase 0 bootstrap)/sdd-reverse-inventory {LegacyProject}(Phase 1 cartographie)- Lire
workspace/old/{LegacyProject}/.sys/inventory.mdpour identifier les unités U-N pertinentes - Pour chaque unité voulue :
/sdd-reverse U-N(Phase 3, séquentiel) - Phase 5 (humain) : Tech Lead revue + complétion
## Project Configdes FEATs - Pré-
/sdd-full:python .sdd/python/sdd_reverse_scripts/check_reverse_feat_for_full.py --feat-path workspace/feats/{n}-*.md /sdd-full {n}(pipeline SDD_Pro standard — workflow EXISTANT inchangé)
Décisions architecturales verrouillées (D1-D7)
À rappeler au Tech Lead s'il pose des questions :
- D1 Language-agnostic : détection auto via
language_signatures.yml. 9+ langages supportés MVP. Confidence cap par langage dans le YAML, jamais hardcodé. - D2 Chunking fin : 1 FEAT = 1 unité fonctionnelle. 1-4 FEATs par page. Grid CRUD = 1 FEAT, modale confirm = 0 FEAT.
- D3 Tech audit : optionnel, skippable, informational. Hors MVP (V2).
- D4 Loader séparé :
loader.reverse.ymlautonome. Aucune édition deloader.yml. - D5 Triggers stricts : cette skill ne hijacke pas sur « vieux code » générique.
- D6 Output français : FEATs, inventory.md, tech-audit.md en FR. Commentaires evidence/confidence en EN.
- D7 DB schema Phase 1 : extraction basique en Phase 1, source de vérité entities. Si absent → entities dégradées à
confidence: medium.
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.

starting-a-reverse-eng is a skill published in the GitHub repository zekiriabd/SDD-Pro (191 stars, last pushed 5d ago), licensed Apache-2.0. It adds 108 tokens to every session and 1,201 once invoked, about $0.0005 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.
