A set of rules for editing Python files. It keeps changes aligned with the project's existing formatting, documentation, imports, type hints, loops, and error handling.

Use it when modifying Python functions or classes, adding imports, handling errors, or matching the project's existing code style.

It prevents small fixes from turning into broad rewrites and avoids adding project patterns that are not already in use. It also keeps code output focused on the parts that changed.

python — Cursor rule for Cursor by inboxpraveen/Minimize-Cursor-Cost

Install

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.

Clone the repo

git clone --depth 1 https://github.com/inboxpraveen/Minimize-Cursor-Cost

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.

When invoked 224 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00224
Opus 5.5	$0.00000	$0.00090
Sonnet 5.5	$0.00000	$0.00045
Haiku 4.5	$0.00000	$0.00022

Security

Grade A, and why

python 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 1mo 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

Python-Specific Rules

Style

Match existing style: black-formatted or not, docstring style, type hint usage
Don't add type hints where none exist unless asked
Don't reformat existing code while fixing something unrelated

Output

For single-function edits: show only that function
For class edits: show only the changed method(s)
Use # ... rest of class unchanged to skip

Imports

Show only net-new import lines needed
Do not reprint the full import block

Common shortcuts

If a pattern repeats across methods, note it once: # same pattern as create_x()
Prefer list comprehensions over loops unless the existing code uses loops
Match existing error handling style (bare except vs specific exceptions)

Never

Don't add if __name__ == "__main__" unless asked
Don't add logging setup unless asked
Don't convert functions to async unless asked

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.
