check-shared-before-scoped

check-shared-before-scoped is a cursor rule for Cursor from hlalljie/agent-workflow-presets. It costs 111 tokens per session, scanned A, original, MIT.

A rule for checking shared code before adding a change for only one component or section. Shared code is logic or styling already used by multiple parts of an application.

In plain words
What is it for?
Use it before adding component-specific CSS, functions, or markup that might duplicate behavior already handled elsewhere.
Why use it?
It helps prevent duplicate fixes and unintended differences between similar components. It also prompts you to decide whether a change should apply more broadly.

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

check-shared-before-scoped 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 7d 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

Before writing a scoped override (targeting a specific component, ID, or section), check if a shared class, function, or component already handles that behavior.

If yes — ask: "This looks like it's handled by [shared thing] for all [types] — should the change apply everywhere or just here?"

Applies to CSS overrides, component-specific logic that mirrors shared logic, and markup added to one variant that others don't have.

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.
