flask-conventions

flask-conventions is a skill for Claude Code, Codex from Cypsy1714/cchad. It costs 17 tokens per session (202 once invoked), scanned A, original, MIT.

A set of conventions for building and reviewing Flask web applications, including app structure, request handling, database access, configuration, and errors.

In plain words
What is it for?
Use it when creating or reviewing Flask apps, especially when organizing features, validating input, connecting to a database, managing configuration, or handling errors.
Why use it?
It reduces tangled code, unsafe database queries, leaked secrets, inconsistent API responses, and hard-to-test application setup.

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

flask-conventions 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.

What it actually says

Flask conventions

Structure

  • Use the application factory pattern (create_app) and register Blueprints per feature, so testing and configuration stay clean.
  • Keep view functions thin; put logic in a service layer or model methods.
  • Load configuration from the environment into a config object; keep secrets out of code.

Requests & data

  • Validate and deserialize input with a schema library (Pydantic / Marshmallow) instead of poking at request.json directly.
  • Use parameterized queries or an ORM (SQLAlchemy); never build SQL from user input.
  • Manage resources (DB sessions) via extensions or app/request lifecycle, not globals.

Practical

  • Return explicit status codes and consistent JSON for APIs.
  • Register error handlers that map exceptions to responses; don't leak stack traces.
  • Keep blueprints and extensions initialized in one place to avoid circular imports.

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.
