vibe-component-reuse

vibe-component-reuse is a cursor rule for Cursor from glide-the/im-dream. It costs 207 tokens per session, scanned A, original, MIT.

A coding rule that tells agents to look for an existing component or module before creating a new one. It favours extending or refactoring suitable code instead of maintaining duplicate implementations.

In plain words
What is it for?
Use it when adding components, modules, pages, or scripts, especially during requirement changes or cleanup of duplicate code paths.
Why use it?
It reduces repeated code and prevents similar features from drifting apart as they change. When reuse is not suitable, it requires recording why a new unit is needed.

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

vibe-component-reuse 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 12d 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

Vibe Component Reuse Rules

Reuse First

  • Before adding a new component/module/page/script, search existing implementation first.
  • If an existing unit can satisfy >=70% semantics, extend or reuse it.
  • Avoid parallel implementations that overlap in behavior.

New Creation Gate

  • Create a new component/module only when reuse is clearly not viable.
  • Document why reuse is not possible in the nearest folder doc.
  • Keep new units single-purpose and composable.

Refactor Preference

  • When requirements change, prefer refactoring current modules over spawning alternates.
  • Remove dead/duplicate paths after migration to prevent overlap drift.

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.
