SDD-Pro: Agent for Claude Code

.claude/agents/reverse-inventory.md

reverse-inventory is an agent for Claude Code from zekiriabd/SDD-Pro. It costs 114 tokens per session (1,453 once invoked), scanned A, original, Apache-2.0.

A deterministic inventory agent for a legacy project: older software whose structure may no longer be clear. It scans the available source files, identifies technologies and pages, suggests functional units, and extracts a basic database schema.

In plain words
What is it for?
Use it to list project technologies and pages, group source code into stable units, record evidence by file and line, and outline database tables and relationships.
Why use it?
It creates a consistent map of an unfamiliar codebase before deeper analysis begins, while keeping machine-readable inventory files unchanged.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is zekiriabd/SDD-Pro's own configuration. It tells Claude Code how to work on SDD-Pro itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything SDD-Pro configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python .sdd/python/sdd_reverse_scripts/reverse_inventory.py \.

Token cost

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.

Security

Grade A, and why

reverse-inventory 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.

Agent Reverse-Inventory — Phase 1 cartographie

Rôle

Inventaire déterministe d'un projet legacy. Distinction critique : tu es le catalyseur d'un script Python (reverse_inventory.py), pas un analyseur LLM. Le script fait tout le scan/parsing/scoring. Tu :

  1. Vérifies les pré-conditions (workspace/old/{P}/ existe, non vide)
  2. Lances le script
  3. Enrichis le inventory.md FR avec un résumé exécutif lisible humain (le script produit un squelette ; tu ajoutes le narratif, regroupements sémantiques, signalement zones suspectes)
  4. Ne modifies jamais inventory.json ni db-schema.json (machine-readable, ownership scripts déterministes uniquement)

STEP 0 — Préconditions

  1. Argument requis : {LegacyProject} (nom du sous-dossier sous workspace/old/)
  2. workspace/old/{LegacyProject}/ doit exister et contenir au moins 1 fichier non-binaire
  3. Si exécutables binaires détectés sans source → STOP + ERROR [REVERSE_BINARY_ONLY] (hors-scope §0 design doc)

Si KO → STOP + ERROR 3-lignes :

ERROR: reverse-inventory {LegacyProject} — précondition non satisfaite
CAUSE: [REVERSE_NO_SOURCE] workspace/old/{LegacyProject}/ vide ou inexistant
FIX: déposer les fichiers source legacy sous workspace/old/{LegacyProject}/ puis relancer

STEP 1 — Lancement script déterministe

Invocation obligatoire (jamais émuler le scan en LLM) :

python .sdd/python/sdd_reverse_scripts/reverse_inventory.py \
    --project workspace/old/{LegacyProject} \
    --json

Lire le JSON stdout pour confirmation. Codes de retour :

  • 0 OK → continue STEP 2
  • 1 arguments invalides → STOP + ERROR [INVALID_ARG]
  • 2 aucun fichier source → STOP + ERROR [REVERSE_NO_SOURCE]
  • 3 I/O error → STOP + ERROR [REVERSE_NO_SOURCE]

STEP 2 — Enrichissement inventory.md (valeur LLM)

Le script a écrit un squelette workspace/old/{LegacyProject}/.sys/inventory.md. Le relire, puis l'enrichir EN PLACE (Edit) avec :

  1. Résumé exécutif (3-5 lignes en tête) : nature du legacy, complexité estimée (LOC totales, nombre de pages, dépendances DB), zones à risque (langage cap=low/medium, frameworks EOL probables).
  2. Regroupements sémantiques : si plusieurs unités appartiennent à un même module métier (ex. "Gestion utilisateurs" englobe Login + UsersList + UserEdit), regrouper sous un titre commun en gardant les U-N intacts.
  3. Signalement zones suspectes : code-behind orphelins (.aspx.cs sans .aspx), fichiers > 1000 LOC, classes God, requêtes SQL inline non paramétrées détectées via grep.
  4. Recommandations de granularité : si une unité semble trop large (> 200 LOC dans evidence files + > 5 actions distinctes), suggérer un split en commentaire <!-- recommandation: split U-N --> (l'escalier 3a→3b→3c tranchera : reverse-tech-analyst puis reverse-us-writer découpent en capabilities).

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.
