tooling-for-apps

tooling-for-apps is a cursor rule for Cursor from SyntaxArc/archipy-plugin. It costs 313 tokens per session, scanned A, original, MIT.

A project tooling guide defines how an ArchiPy app installs dependencies and runs formatting, linting, type checks, acceptance tests, and pre-commit hooks. Acceptance tests check complete user-facing behaviour; pre-commit hooks run checks before a commit is created.

In plain words
What is it for?
Use it to manage packages with uv, run Ruff and ty, execute Behave tests, and use the app's existing Makefile, task runner, or CI commands.
Why use it?
It avoids inconsistent commands and duplicate dependencies. It also encourages running the smallest relevant check during development and the full project gate before handoff.

Cursor rule for Cursor

Written for Cursor: a Cursor rule (.mdc).

Good fit Use it to manage packages with uv, run Ruff and ty, execute Behave tests, and use the app's existing Makefile, task runner, or CI commands.

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

tooling-for-apps 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 today.

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

Tooling for ArchiPy Apps

Package Management

Use uv; never install project packages with bare pip.

uv sync
uv add "archipy[redis,fastapi]"
uv add --group dev ruff ty pre-commit
  • Inspect pyproject.toml before adding dependencies; do not duplicate an existing direct/transitive requirement.
  • Install only ArchiPy extras required by the app.
  • Commit uv.lock changes when dependency changes are intentional.

Project Commands

Prefer commands already defined by the app's Makefile, pyproject.toml, task runner, or CI. Do not assume ArchiPy library Make targets exist. When no wrapper exists, typical direct checks are:

uv run ruff format .
uv run ruff check .
uv run ty check
uv run behave features/example.feature
uv run pre-commit run --all-files

Run the narrowest relevant test during iteration, then the app's complete required gate before handoff. Use Behave as the primary ArchiPy acceptance-test style; follow project-specific unit-test tooling when present.

Hooks

If the app configures pre-commit, install/run it through uv. Do not add or rewrite hook configuration unless the task requires tooling changes. Fix generated formatting/lint changes before reporting completion.

Changes

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.
