aiwg-regenerate-cursorrules

aiwg-regenerate-cursorrules is a skill for Claude Code, Codex from jmagly/aiwg. It costs 22 tokens per session (1,430 once invoked), scanned A, original, MIT.

A project command that rebuilds .cursorrules, the instruction file used by Cursor, from the current project while preserving selected team and organisation rules. It can keep generated context in a separate file or insert it directly.

In plain words
What is it for?
Use it to update Cursor project rules, preserve marked content, inspect what was kept, or replace the file completely when required.
Why use it?
It refreshes Cursor's instructions without discarding important existing guidance. Backups and preview mode help you verify the proposed changes first.

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

aiwg-regenerate-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 9d 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.

Regenerate .cursorrules

Regenerate the .cursorrules file for Cursor IDE integration, analyzing current project state while preserving team directives and organizational requirements.

Hook file approach (default): Generates AIWG-cursor.md and adds @AIWG-cursor.md directive to .cursorrules. Note: Cursor's @-link support in .cursorrules is partially confirmed — see #444.

Full inject (--full-inject): Embeds AIWG content inline with AIWG markers (safe fallback).

Parameters

Flag Description
--no-backup Skip creating backup file
--dry-run Preview changes without writing
--show-preserved List all detected preserved content and exit
--full Full regeneration, preserve nothing (destructive)

Execution Steps

Step 1: Create Backup

Unless --no-backup specified:

  1. Check if .cursorrules exists
  2. If exists, copy to .cursorrules.backup-{YYYYMMDD-HHMMSS}
  3. Report backup location

Step 2: Extract Preserved Content

Same preservation patterns as other platforms:

  1. Explicit Preserve Blocks: <!-- PRESERVE --> ... <!-- /PRESERVE -->
  2. Preserved Section Headings: Team *, Org *, Definition of Done, etc.
  3. Inline Directives: Lines with directive keywords

Step 3: Analyze Project

  • Languages and package managers
  • Development commands
  • Test framework
  • CI/CD configuration
  • Directory structure
  • Cursor-specific configuration in .cursor/

Step 4: Detect AIWG State

Check installed frameworks by scanning:

  • .cursor/agents/ for deployed agents
  • .cursor/rules/ for MDC rules
  • .cursor/commands/ for commands

Read registry for framework versions.

Step 5: Generate .cursorrules

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.
