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 | $0.00818 | $0.00818 |
| Opus 5.5 | $0.00327 | $0.00327 |
| Sonnet 5.5 | $0.00164 | $0.00164 |
| Haiku 4.5 | $0.00082 | $0.00082 |
Grade A, and why
project-architect CLAUDE.md 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 2mo 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
project-architect — Plugin Claude Code
Plugin de préparation de projet de développement, de la qualification initiale à
la gate pré-dev. Une seule commande /project-architect, workflow adaptatif
S/M/L/XL.
Architecture
8 phases séquentielles :
- QUALIFIER — Taille du projet (S/M/L/XL) et Go/No-Go
- COMPRENDRE — Contexte, existant, contraintes
- STRATÉGISER — Stratégie et positionnement
- SPÉCIFIER — Cahier des charges fonctionnel
- DESIGNER — Brief UX/UI et direction artistique (24 questions, 9 blocs)
- ARCHITECTURER — Architecture technique
- PLANIFIER — Planning et budget
- VALIDER — Gate pré-dev et fichiers-pont (
CLAUDE.md,implementation-roadmap.md)
Matrice adaptative : data/adaptation-matrix.json contrôle quelles
questions et quels livrables s'appliquent selon la taille S/M/L/XL. Invariant à
préserver : les items sont monotones (S <= M <= L <= XL) pour chaque phase.

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.

project-architect CLAUDE.md is an instructions file published in the GitHub repository arnwaldn/project-architect (1 stars, last pushed 2mo ago), licensed MIT. It adds 818 tokens to every session, about $0.0033 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 2026-08-31.
