cursorrules

cursorrules is a cursor rule for Cursor from kruschdev/krusch-context-mcp. It costs 503 tokens per session, scanned A, original, MIT.

A set of instructions for a coding agent connected to a persistent memory and code-search system. It tells the agent how to load project state, past lessons, priorities, and relevant code before working.

In plain words
What is it for?
Use it to brief an agent on a codebase, retrieve related files, review unresolved work, and ground larger architectural edits in stored project context.
Why use it?
It reduces the need to repeat project context across sessions and helps the agent check existing decisions and code before making changes.

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

cursorrules 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.

Krusch Context Protocol for Cursor Agents

You are connected to krusch-context-mcp, a persistent working memory engine. You MUST follow this lifecycle protocol across all coding sessions:

1. Session Start: State Hydration

At the beginning of your session or before starting a new task, call krusch_context_retrieve with include_state: true:

{
  "query": "*",
  "include_state": true,
  "limit_tokens": 4000
}

Review the active project invariants, recent architectural decisions, open blockers, and decay review items before proposing edits.

2. During Work: Recording Critical Knowledge

Whenever you make a lasting architectural choice, resolve an elusive regression, or establish a non-negotiable rule, call krusch_context_remember:

{
  "category": "decision",
  "content": "<concrete explanation of the design choice or invariant>"
}

Category MUST be one of: decision | invariant | bug | lesson | blocker.

Handling Near-Duplicate Warnings

If krusch_context_remember returns a warning: 'near_duplicate', read the candidate ID. If your new knowledge updates or replaces that candidate, call krusch_context_revise:

{
  "action": "supersede",
  "target_id": <candidate_id>,
  "content": "<updated authoritative rule>",
  "category": "decision"
}

3. Retiring Stale Knowledge

If a rule, secret, endpoint, or constraint is revoked, call krusch_context_revise with action: 'invalidate' and a mandatory reason:

{
  "action": "invalidate",
  "target_id": <old_id>,
  "reason": "<why this rule or invariant is no longer valid>"
}

4. Pre-Commit / Pre-Edit Audit

Before committing code or submitting final multi-file edits, audit your changes against recorded project invariants with krusch_context_nudge:

{
  "trigger": "pre_commit",
  "code": "<diff or modified code snippet>"
}

Address any high-severity invariant violations before finishing.

5. Diagnostic Hygiene

To verify store health or check for decaying memories (>30 days), call krusch_context_health:

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.
