+# RTK (Rust Token Killer) - Token-Optimized Commands
+
+## Golden Rule
+
+**Always prefix commands with `rtk`**. If RTK has a dedicated filter, it uses it. If not, it passes through unchanged. This means RTK is always safe to use.
+
+**Important**: Even in command chains with `&&`, use `rtk`:
+```bash
+# ❌ Wrong
+git add . && git commit -m "msg" && git push
+
+# ✅ Correct
+rtk git add . && rtk git commit -m "msg" && rtk git push
+```
+
+## RTK Commands by Workflow
+
+### Build & Compile (80-90% savings)
+```bash
+rtk cargo build         # Cargo build output
+rtk cargo check         # Cargo check output
+rtk cargo clippy        # Clippy warnings grouped by file (80%)
+rtk tsc                 # TypeScript errors grouped by file/code (83%)
+rtk lint                # ESLint/Biome violations grouped (84%)
+rtk prettier --check    # Files needing format only (70%)
+rtk next build          # Next.js build with route metrics (87%)
+```
+
+### Test (90-99% savings)
+```bash
+rtk cargo test          # Cargo test failures only (90%)
+rtk vitest run          # Vitest failures only (99.5%)
+rtk playwright test     # Playwright failures only (94%)
+rtk test <cmd>          # Generic test wrapper - failures only
+```
+
+### Git (59-80% savings)
+```bash
+rtk git status          # Compact status
+rtk git log             # Compact log (works with all git flags)
+rtk git diff            # Compact diff (80%)
+rtk git show            # Compact show (80%)
+rtk git add             # Ultra-compact confirmations (59%)
+rtk git commit          # Ultra-compact confirmations (59%)
+rtk git push            # Ultra-compact confirmations
+rtk git pull            # Ultra-compact confirmations
+rtk git branch          # Compact branch list
+rtk git fetch           # Compact fetch
+rtk git stash           # Compact stash
+rtk git worktree        # Compact worktree
+```
+
+Note: Git passthrough works for ALL subcommands, even those not explicitly listed.
+
+### GitHub (26-87% savings)
+```bash
+rtk gh pr view <num>    # Compact PR view (87%)
+rtk gh pr checks        # Compact PR checks (79%)
+rtk gh run list         # Compact workflow runs (82%)
+rtk gh issue list       # Compact issue list (80%)
+rtk gh api              # Compact API responses (26%)
+```
+
+### JavaScript/TypeScript Tooling (70-90% savings)
+```bash
+rtk pnpm list           # Compact dependency tree (70%)
+rtk pnpm outdated       # Compact outdated packages (80%)
+rtk pnpm install        # Compact install output (90%)
+rtk npm run <script>    # Compact npm script output
+rtk npx <cmd>           # Compact npx command output
+rtk prisma              # Prisma without ASCII art (88%)
+```
+
+### Files & Search (60-75% savings)
+```bash
+rtk ls <path>           # Tree format, compact (65%)
+rtk read <file>         # Code reading with filtering (60%)
+rtk grep <pattern>      # Search grouped by file (75%)
+rtk find <pattern>      # Find grouped by directory (70%)
+```
+
+### Analysis & Debug (70-90% savings)
+```bash
+rtk err <cmd>           # Filter errors only from any command
+rtk log <file>          # Deduplicated logs with counts
+rtk json <file>         # JSON structure without values
+rtk deps                # Dependency overview
+rtk env                 # Environment variables compact
+rtk summary <cmd>       # Smart summary of command output
+rtk diff                # Ultra-compact diffs
+```
+
+### Infrastructure (85% savings)
+```bash
+rtk docker ps           # Compact container list
+rtk docker images       # Compact image list
+rtk docker logs <c>     # Deduplicated logs
+rtk kubectl get         # Compact resource list
+rtk kubectl logs        # Deduplicated pod logs
+```
+
+### Network (65-70% savings)
+```bash
+rtk curl <url>          # Compact HTTP responses (70%)
+rtk wget <url>          # Compact download output (65%)
+```
+
+### Meta Commands
+```bash
+rtk gain                # View token savings statistics
+rtk gain --history      # View command history with savings
+rtk discover            # Analyze Codex sessions for missed RTK usage
+rtk proxy <cmd>         # Run command without filtering (for debugging)
+rtk init                # Add RTK instructions to AGENTS.md
+rtk init --global       # Add RTK to ~/.Codex/AGENTS.md
+```
+
+## Token Savings Overview
+
+| Category | Commands | Typical Savings |
+|----------|----------|-----------------|
+| Tests | vitest, playwright, cargo test | 90-99% |
+| Build | next, tsc, lint, prettier | 70-87% |
+| Git | status, log, diff, add, commit | 59-80% |
+| GitHub | gh pr, gh run, gh issue | 26-87% |
+| Package Managers | pnpm, npm, npx | 70-90% |
+| Files | ls, read, grep, find | 60-75% |
+| Infrastructure | docker, kubectl | 85% |
+| Network | curl, wget | 65-70% |
+
+Overall average: **60-90% token reduction** on common development operations.

-# Master Plan - Résolution Dashboard 502
+# Plan - Commit et Push des modifications locales
 
 ## Contexte
-Le dashboard affiche une erreur 502 Bad Gateway. L'API `api.ffnancy.fr` semble fonctionner de l'extérieur, mais la connexion interne depuis le conteneur Next.js échoue, probablement à cause d'URL codées en dur qui ne respectent pas les variables d'environnement.
+L'utilisateur a demandé de commiter et pusher ses modifications locales actuelles. L'analyse montre qu'il s'agit d'une implémentation majeure du chargement en streaming pour la grille de produits (11 fichiers modifiés et 2 fichiers non suivis).
 
 ## Focus Actuel
-Harmonisation des URL API dans le code source pour utiliser `FF_API_BASE_URL`.
+Validation de la compilation, staging des fichiers, création du commit et push vers le dépôt distant.
 
 ## Master Plan
-- [x] Analyser tous les appels API dans `pg-ff-client.ts` et `api-ff-client.ts`
+- [x] Analyser l'état actuel de Git et identifier les fichiers modifiés/ajoutés (Fait)
-- [x] Centraliser la constante `FF_API_BASE` dans `pg-ff-client.ts`
+- [ ] Vérifier la compilation globale avec `rtk tsc` pour s'assurer que tout est propre
-- [x] Remplacer les URL codées en dur par `${FF_API_BASE}`
+- [ ] Ajouter les fichiers à l'index Git (`rtk git add`)
-- [x] Vérifier la configuration Docker et les variables d'environnement
+- [ ] Créer le commit avec un message descriptif et professionnel (`rtk git commit`)
-
+- [ ] Envoyer les modifications sur la branche distante (`rtk git push`)
-- [x] Tester via `/api/diag` (Implémentation validée)
+- [ ] Valider le statut Git final
-
 
 ## Progress Log
-- Analyse initiale terminée : identification d'une URL codée en dur à la ligne 564 de `pg-ff-client.ts`.
+- **2026-05-26 13:31** : Analyse initiale des modifications. Identification de l'implémentation de la grille en streaming (`src/features/grid` et `/api/grid`). Initialisation du plan de commit et push.
-- Harmonisation effectuée dans `pg-ff-client.ts`.
-- Vérification des autres fichiers `src` effectuée : tous utilisent désormais `FF_API_BASE`.
