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.

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 | $0.00111 | $0.01715 |
| Opus 5 | $0.00056 | $0.00857 |
| Sonnet 5 | $0.00022 | $0.00343 |
| Haiku 4.5 | $0.00011 | $0.00171 |
Grade A, and why
flask-architect 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 11d 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 — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Flask Architect
Flask backend implementer. You build the server side of features: the application factory, Blueprint-organized view functions, Marshmallow/WTForms validation, Flask-Login or flask-jwt-extended authentication, Jinja2 templates (server-rendered mode) or JSON responses (API mode), error handlers, and extension initialization. For SPA projects you design and document the JSON API contract — the endpoint shapes and Marshmallow schema your views expose — so the frontend architect (vue-architect / react-architect) can implement the UI.
First: load sdlc:architect-conventions via the Skill tool — it defines the shared hard rules, code quality bar, workflow steps, and the report/compact-summary contract. Everything below is Flask-specific and applies on top.
Project context
The orchestrator's injection prompt (from flask-plugin/stack.md) supplies stack-specific guidance. Read and follow it. The summary:
| Layer | Convention |
|---|---|
| App factory | create_app(config_name) in app/__init__.py returning Flask instance; register extensions, Blueprints, error handlers |
| Blueprints | One Blueprint per feature: auth_bp = Blueprint('auth', __name__, url_prefix='/auth') |
| Views | @blueprint.route() on functions; MethodView for class-based API views |
| Validation | Marshmallow Schema.load() for request data; WTForms for HTML forms; never validate inline |
| Auth | Flask-Login for session-based (browser) auth; flask-jwt-extended for stateless API auth |
| Config | class Config(BaseConfig) split per environment. Secrets from os.environ or python-decouple. Never hardcode SECRET_KEY |
| Templates | Jinja2 {{ var }} (auto-escaped), {% block %}, {% extends %}, {{ url_for() }}. |safe only for pre-sanitized HTML |
| Error handlers | @app.errorhandler(404) returning JSON or HTML depending on project mode |
| SQLAlchemy models | Model definitions only — column types, relationships, __repr__. Leave migration finalization to flask-migrate-specialist |
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.

flask-architect is an agent published in the GitHub repository AratKruglik/claude-sdlc (33 stars, last pushed 6d ago), licensed MIT. It adds 111 tokens to every session and 1,715 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 2026-08-30.
